Description

[Technical field]

[0001] The present invention relates to a process plan creation device, a process plan creation system, a process plan creation method, and a program for creating a process plan for pipeline construction. [Background technology]

[0002] In general, in pipeline construction such as water pipe construction, a process plan is created, and work is carried out according to the created process plan. As a process plan creation system for pipeline construction, for example, as disclosed in Patent Document 1, a process plan creation system for water pipe construction is known that has an information acquisition unit that acquires water pipe related information, a process time calculation unit that calculates a process time based on the water pipe related information, and a process plan creation unit that creates a process plan for water pipe construction using the process time.

[0003] The above-mentioned Patent Document 1 discloses that when calculating the process time, water pipe construction related information including information related to site conditions is used. The above-mentioned Patent Document 1 also discloses that the information related to site conditions includes information on parallel work and information on parallel use of work machines. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2023-094996 A Summary of the Invention [Problem to be solved by the invention]

[0005] As described above, Patent Document 1 discloses that the information related to the site conditions includes information on parallel work and information on the parallel use of work machines. However, Patent Document 1 does not disclose the specific details of how to reflect the parallel work carried out at an actual pipeline construction site in the creation of a process plan.

[0006] At pipeline construction sites, work progresses in various patterns, including parallel work. The progress of pipeline construction varies greatly depending on the pattern of work progress. Therefore, it is necessary to create accurate pipeline construction schedules according to the various work progress patterns.

[0007] An object of the present invention is to realize a process plan creation device that can create a pipeline construction process plan with high accuracy in accordance with various work progress patterns. [Means for solving the problem]

[0008] A process plan creation device for pipeline construction according to one embodiment of the present invention is a device for creating a process plan for pipeline construction. The process plan creation device has a data storage unit in which basic data used for creating the process plan is stored, an information acquisition unit that acquires information on a work progress pattern in the pipeline construction and construction information required for creating the process plan, a work time calculation unit that calculates a work time according to the work progress pattern using the basic data stored in the data storage unit and the information acquired by the information acquisition unit, and a process plan creation unit that creates the process plan based on the work time calculated by the work time calculation unit (first configuration).

[0009] This makes it possible to calculate the work time according to the work progress pattern in the pipeline construction and to create a process plan according to the work progress pattern. The work progress pattern includes, for example, a single work pattern in which each process of excavation, piping, and backfilling is performed in sequence by one team, a partial parallel work pattern in which some of the processes are performed in parallel by multiple teams while the remaining processes are performed by all the teams, and a parallel work pattern in which all of the processes are performed in parallel by multiple teams.

[0010] With the above-mentioned configuration, a process plan can be created according to the above-mentioned single operation pattern, partial parallel operation pattern, and parallel operation pattern, so that the process plan can be created with high accuracy. Moreover, the process plan can be easily created using the basic data stored in the data storage unit, the information related to the work progress pattern acquired by the information acquisition unit, and the construction information required for creating the process plan.

[0011] In the first configuration, the basic data stored in the data storage unit includes data on a standard work time for each process in the pipeline construction. The work time calculation unit calculates the work time for each process according to the work progress pattern using the data on the standard work time (second configuration).

[0012] This makes it possible to easily calculate the work time for each process of the pipeline construction, and therefore the work time according to the work progress pattern can also be easily calculated.

[0013] In the second configuration, the operation time calculation unit calculates a plurality of operation times according to the operation progress pattern using data on the standard operation time. The process plan creation unit creates the process plan using the longest operation time among the plurality of operation times calculated by the operation time calculation unit (third configuration).

[0014] This makes it possible to prevent the work time calculated by the process plan creation device from being shorter than the work time for the actual pipeline construction work, and therefore makes it possible to create a process plan for the pipeline construction work that can be carried out with ample time to spare in relation to the progress of the actual pipeline construction work.

[0015] In the first configuration, the work time calculation unit increases the number of pipes on which the pipeline work is to be performed within a predetermined period and calculates the work time for each number of pipes. When the total work time calculated by the work time calculation unit exceeds a specified value, the process plan creation unit creates the process plan based on the work time when the number of pipes on which the pipeline work is to be performed within the predetermined period is reduced by one (fourth configuration).

[0016] This makes it possible to easily calculate the process period according to the number of pipes that can be worked on within a given period (for example, one day), thereby enabling the process plan to be created with greater accuracy.

[0017] In any one of the first to fourth configurations, the work progress pattern includes a work pattern in which each of the excavation, piping and backfilling processes in the pipeline construction is carried out independently or at least some of these processes are carried out in parallel (fifth configuration).

[0018] This makes it possible to calculate the work time and create a process plan taking into consideration the work progress pattern in each process of excavation, piping, and backfilling in the pipeline construction, thereby making it possible to create the process plan with higher accuracy.

[0019] A pipeline construction process plan creation system according to one embodiment of the present invention is a system for creating a pipeline construction process plan, comprising an input terminal and a server capable of communicating with the input terminal. The input terminal has an input unit for inputting information on the work progress pattern in the pipeline construction and construction information required for creating the process plan, and a terminal-side communication unit capable of transmitting the information input to the input unit to the server. The server has a server-side communication unit for receiving the information transmitted from the terminal-side communication unit, a data storage unit in which basic data used for creating the process plan is stored and the information received by the server-side communication unit is stored, a work time calculation unit for calculating a work time according to the work progress pattern using the basic data and the information stored in the data storage unit, and a work plan creation unit for creating the process plan based on the work time calculated by the work time calculation unit (sixth configuration).

[0020] This makes it possible to realize a system that can calculate work time according to the work progress pattern in pipeline construction and create a process plan according to the work progress pattern. This system makes it possible to create a process plan with high accuracy. Moreover, the system makes it possible to easily create a process plan using basic data stored in the data storage unit, information related to the work progress pattern acquired by the information acquisition unit, and construction information required for creating the process plan.

[0021] A method for creating a process plan for pipeline construction according to one embodiment of the present invention is a method for creating a process plan for pipeline construction by the above-mentioned process plan creation device. The process plan creation method includes a data acquisition step in which a work time calculation unit of the process plan creation device acquires basic data used for creating the process plan from a data storage unit of the process plan creation device, an information acquisition step in which an information acquisition unit of the process plan creation device acquires information on a work progress pattern in the pipeline construction and construction information required for creating the process plan, a work time calculation step in which the work time calculation unit calculates a work time according to the work progress pattern using the basic data acquired in the data acquisition step and the information acquired in the information acquisition step, and a process plan creation step in which the process plan creation unit of the process plan creation device creates the process plan based on the work time calculated in the work time calculation step (first method).

[0022] This realizes a method for calculating work time according to a work progress pattern in pipeline construction and creating a process plan according to the work progress pattern. This method allows the process plan to be created with high accuracy. Moreover, this method allows the process plan to be easily created using the basic data acquired in the data acquisition step, the information related to the work progress pattern acquired in the information acquisition step, and the construction information required for creating the process plan.

[0023] A program for creating a pipeline construction process plan in one embodiment of the present invention causes a computer to acquire basic data to be used in creating the process plan from a data storage unit, acquire information relating to the work progress pattern in the pipeline construction and construction information necessary for creating the process plan, calculate work time according to the work progress pattern using the basic data and the acquired information, and create the process plan based on the calculated work time (first program).

[0024] This makes it possible to realize a program that can calculate work time according to the work progress pattern in pipeline construction and create a process plan according to the work progress pattern. By executing this program, a process plan can be created with high accuracy. Moreover, the program makes it possible to easily create a process plan using basic data, information related to the work progress pattern, and construction information required for creating the process plan. Effect of the Invention

[0025] A pipeline construction process plan creation device according to one embodiment of the present invention acquires information regarding work progress patterns in pipeline construction and construction information necessary for creating a process plan, calculates work time according to the work progress pattern using basic data stored in a data storage unit and the information acquired by an information acquisition unit, and creates a process plan based on the work time.

[0026] This makes it possible to calculate the work time according to the work progress pattern in the pipeline construction and to create a process plan according to the work progress pattern. Therefore, it is possible to realize a process plan creation device that can create a pipeline construction process plan with high accuracy according to various work progress patterns.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0028] Each embodiment will be described below with reference to the drawings. In each drawing, the same parts are given the same reference numerals, and the description of the same parts will not be repeated. Note that the dimensions of the components in each drawing do not faithfully represent the actual dimensions of the components and the dimensional ratios of each component.

[0029] In the following description, the terms "fix," "connect," and "attach" (hereinafter referred to as "fixing") include not only cases where members are directly fixed to each other, but also cases where members are fixed to each other via other members. In other words, in the following description, the terms "fixing" include the meanings of direct and indirect fixing of members to each other.

[0030] [Embodiment 1] (Pipeline construction process planning device) Fig. 1 is a functional block diagram showing a schematic configuration of a process plan creation device 1 according to a first embodiment of the present invention. The process plan creation device 1 creates a process plan for pipeline construction and outputs it, for example, as shown in Fig. 2. Fig. 2 is a diagram showing an example of an output of a process plan. The process plan output from the process plan creation device 1 may be displayed, for example, by numerical values, characters, etc., or may be displayed by a graph or diagram. Furthermore, the process plan creation device 1 may output only data as the process plan.

[0031] The pipeline construction includes, for example, construction for forming pipelines such as water pipe construction, sewer pipe construction, agricultural water piping construction, etc. The following will explain the case of water pipe construction, but the invention can be similarly applied to construction for forming other pipelines.

[0032] The process plan creation device 1 may be realized, for example, by a computer device capable of executing a program, or may be realized by a dedicated device.

[0033] The process plan creation device 1 includes an information acquisition unit 11, a task time calculation unit 12, a process plan creation unit 13, and a data storage unit .

[0034] The information acquisition unit 11 acquires a portion of information necessary for the process plan. Specifically, the information acquisition unit 11 acquires work progress information, which is information about the work progress pattern in water pipe construction work, and construction information necessary for creating the process plan.

[0035] The work progress pattern means a pattern of how each process is carried out when constructing a plurality of water pipes. Specifically, the work progress pattern includes an all-process parallel work pattern in which each process is carried out in parallel, a partial parallel work pattern in which some of the processes are carried out in parallel, an independent work pattern in which the processes are carried out independently, etc. The work progress pattern also includes patterns in which the work time of each process is different in the all-process parallel work pattern, the partial parallel work pattern, and the independent work pattern.

[0036] Examples of each work pattern are shown in Figs. 3 to 5. Fig. 3 is a diagram showing an example of a timetable for each process in an independent work pattern. Fig. 4 is a diagram showing an example of a timetable for each process in a partially parallel work pattern. Fig. 5 is a diagram showing an example of a timetable for each process in an all-process parallel work pattern. Note that Figs. 3 to 5 show timetables for a construction project to lay two water pipes underground on a paved road.

[0037] First, each process shown in FIG. 3 to FIG. 5 will be described. The processes of water pipe construction include a pavement excavation process, an excavation process, a piping process, a backfilling process, a surveying process, a photo management process, and the like. The pavement excavation process is a process of excavating a pavement plate of a road or the like. The excavation process is a process of excavating the ground to form a trench in which a water pipe can be installed underground. The piping process is a process of connecting the water pipes to each other after carrying them into the trench. The backfilling process is a process of backfilling the water pipes connected in the trench and paving the surface to return the road to its original paved state. The surveying process is a process of measuring various dimensions after the water pipes are installed. The photo management process is a process of taking and managing photos of the installed state of the water pipes.

[0038] As shown in FIG. 3, in the independent work pattern, when laying multiple water pipes, the pavement excavation process and the excavation process each excavate an area in which multiple water pipes can be laid. That is, in the pavement excavation process, first, the pavement slab is excavated in an area in which the multiple water pipes can be laid. After the pavement excavation process is completed, in the excavation process, the ground is excavated in an area in which the multiple water pipes can be laid to form a trench. Then, in the piping process, the multiple water pipes are carried into the trench and joined together. In this state, the multiple water pipes are subjected to dimensional measurements in a surveying process and photographed in a photo management process. Then, in a backfilling process, the multiple water pipes are backfilled and the surface is paved.

[0039] In this way, in the independent work pattern shown in Fig. 3, each process is performed sequentially without overlapping. That is, in the independent work pattern, all the workers in one team work on each process together.

[0040] Even in the partially parallel work pattern shown in FIG. 4, when laying multiple water pipes, the pavement excavation process and the excavation process each excavate a range in which multiple water pipes can be laid. When the excavation of the trench is completed to a range in which the first water pipe can be laid in the excavation process, a worker from another team performs the piping work of the first water pipe in the trench while excavation for laying the second water pipe is being performed. That is, the timing of the excavation process for laying the second water pipe and the piping process for piping the first water pipe overlap. The piping work of the second water pipe is performed after the excavation of the trench is completed to a range in which the second water pipe can be laid in the excavation process. In the example shown in FIG. 4, the subsequent processes are the same as those in the example shown in FIG. 3.

[0041] In the all-process parallel work pattern shown in Fig. 5, when laying multiple water pipes, after the pavement slab is excavated in an area where the first water pipe can be laid in the pavement excavation process, while the pavement slab is being excavated to lay the second water pipe, another team of workers excavates the ground in an area where the first water pipe can be laid in the excavation process. That is, the pavement excavation process for laying the second water pipe and the excavation process for laying the first water pipe overlap in timing. The excavation process for laying the second water pipe is performed after the pavement excavation process is completed in an area where the second water pipe can be laid.

[0042] In the excavation process, the ground is excavated to a range where the first water pipe can be laid to form a trench, and then, as a piping process, the first water pipe is carried into the trench and joined to another water pipe. At this time, the ground is excavated to a range where the second water pipe can be laid at the same time. That is, the excavation process for laying the second water pipe and the piping process for laying the first water pipe overlap in timing. The piping process for laying the second water pipe is performed after the excavation of the ground to a range where the second water pipe can be laid is completed in the excavation process.

[0043] After the first water pipe is laid in the trench in the piping process, the first water pipe is backfilled in the backfilling process. At this time, the second water pipe is laid in the trench formed in the excavation process at the same time. That is, the piping process for laying the second water pipe and the backfilling process for backfilling the first water pipe overlap in timing. The backfilling process for backfilling the second water pipe is performed after the second water pipe is laid in the trench in the piping process.

[0044] In this way, in the partial parallel operation pattern shown in Fig. 4 and the all-process parallel operation pattern shown in Fig. 5, the timing of at least some of the processes overlap. That is, in the partial parallel operation pattern and the all-process parallel operation pattern, workers in multiple teams work on at least some of the processes simultaneously in parallel.

[0045] In the example shown in Fig. 5, for the sake of simplicity, the work is described without including the surveying process and the photo management process. The all-process parallel work pattern shown in Fig. 5 may include the surveying process and the photo management process.

[0046] The work progress information includes information such as which work progress pattern the worker creating the process plan has selected from among the above-mentioned work progress patterns.

[0047] The construction information includes information on the design and environment of the water pipe construction work, among the information required for creating a process plan. More specifically, the construction information includes construction design information and environmental information.

[0048] The construction design information includes information obtained by designing the water pipe construction. Specifically, the construction design information includes design information such as the width and depth of the trench to be excavated, the structure of the pavement (the thickness of each layer that constitutes the pavement), the type, size, and length of the water pipe, etc. The construction design information is obtained based on a designed pipeline diagram.

[0049] The environmental information includes information on the environment of the site where the water pipe construction work is carried out, and information on site conditions such as the number of workers and the work machines to be used. Specifically, the environmental information includes information on the ground such as soil and groundwater at the site where the water pipe is to be laid, information on underground buried objects such as pipes that cross the ground, information on the number of workers, information on the number of earth-transporting vehicles and work machines, etc.

[0050] The data storage unit 14 stores basic data used for creating a construction plan. The basic data includes basic data for construction planning and basic material data.

[0051] The basic data for construction planning includes basic data on work time according to each work content. Specifically, the basic data for construction planning includes data on work time according to excavation depth, data on piping work time according to the type and length of water pipe, data on backfill work time according to the size of water pipe, etc. The work time is a standard work time per unit work amount, which is a standard unit of work amount. The work time may be a standard work time, a work time that differs by region, or a work time that differs depending on the number and characteristics of construction workers.

[0052] The basic material data includes data on water pipes and piping parts. Specifically, the basic material data includes, for example, information on the type, size, length, etc. of the water pipes, and data on the type of valves, etc., which are the piping parts.

[0053] The work time calculation unit 12 calculates the work time for each type of work in each process based on the work progress information and the construction information acquired by the information acquisition unit 11 and the basic data stored in the data storage unit 14. In detail, the work time calculation unit 12 uses the construction information and the basic data to calculate the amount of work expected for each type of work in each process, and multiplies the calculated amount of work by the work time per unit amount of work to calculate the work time for each type of work. For example, the work time calculation unit 12 calculates the amount of excavation work from the result of multiplying the width of the excavation by the length of the water pipe, and calculates the excavation work time by multiplying the amount of work by the work time per unit amount of excavation work. The type of work means the type of work performed in each process. The type of work includes, for example, pavement slab demolition and loading work in which a pavement slab is demolished and loaded, pipe laying work, etc.

[0054] The work time calculation unit 12 calculates the work time as described above for each work type according to the work progress pattern in the work progress information. The work time calculation unit 12 outputs the work time for each work type according to the work progress pattern.

[0055] The process plan creation unit 13 creates a process plan using the work time calculated by the work time calculation unit 12. Specifically, the process plan creation unit 13 creates a process plan for water pipe construction by accumulating the work time calculated for each type of work according to the work progress pattern in the work progress information.

[0056] When laying a plurality of water pipes using a partial parallel work pattern or an all-process parallel work pattern, the process plan creation unit 13 creates a process plan by distinguishing between the work time of the process for the Nth water pipe and the work time of the process for the N-1th water pipe which is performed at the same time as the Nth water pipe, whichever is longer. For example, the process plan creation unit 13 creates a process plan by distinguishing between the time of the excavation process for laying the Nth water pipe and the time of the piping process for the N-1th water pipe, whichever is longer. Figure 6 is a diagram showing an example of a timetable when the work time of the piping process for the first water pipe is longer than the work time of the excavation process for the second water pipe in the partial parallel work pattern shown in Figure 4.

[0057] In this way, the process plan creation device 1 separates the work progress patterns when the process timings overlap, and also separates the work progress patterns according to the length of the work time of the process. This makes it possible to realize a process plan creation device 1 that can create a process plan according to various work progress patterns performed at a water pipe construction site.

[0058] When laying multiple water pipes using a partial parallel work pattern or an all-process parallel work pattern as described above, the process plan creation unit 13 determines whether the total work time in the created process plan (the work time for laying N water pipes) falls within a reference time.

[0059] If the total work time falls within the reference time, the process plan creation unit 13 increases the number of water pipes to be laid by one, causes the work time calculation unit 12 to calculate the laying work time, and uses the result to calculate the total work time for N+1 pipes. If the total work time does not fall within the reference time, the process plan creation unit 13 creates and outputs a process plan for laying water pipes that are one less (N-1 pipes) than the N pipes for which the total work time was calculated. This makes it possible to create a process plan for laying the maximum number of water pipes that can be laid within the reference time.

[0060] The reference time may be, for example, the amount of time that work can be done in one day, a portion of the work time in one day, or the amount of time that work can be done in a predetermined period that is longer than one day.

[0061] Fig. 7 is a diagram showing an example of a timetable when three water pipes are laid using a partially parallel work pattern (an excavation process and a piping process are performed in parallel). As shown in Fig. 7, laying three water pipes using a partially parallel work pattern exceeds the reference time (the range shown by the thick line in Fig. 7). In this case, the process plan creation unit 13 creates a process plan according to the timetable for laying two water pipes, for example, as shown in Fig. 4.

[0062] The process plan creation device 1 according to this embodiment is a device that creates a process plan for water pipe construction. The process plan creation device 1 has a data storage unit 14 that stores basic data used to create the process plan, an information acquisition unit 11 that acquires information on the work progress pattern in the water pipe construction and construction information required to create the process plan, a work time calculation unit 12 that calculates a work time according to the work progress pattern using the basic data stored in the data storage unit 14 and the information acquired by the information acquisition unit 11, and a process plan creation unit 13 that creates the process plan based on the work time calculated by the work time calculation unit 12.

[0063] This makes it possible to calculate the work time according to the work progress pattern in water pipe construction and to create a process plan according to the work progress pattern. The work progress pattern includes, for example, a single work pattern in which one team performs each process of excavation, piping, and backfilling in order, a partial parallel work pattern in which multiple teams perform the excavation and piping processes in parallel among the above processes, while all the teams perform the backfilling, and a parallel work pattern in which multiple teams perform all the above processes in parallel.

[0064] With the above-mentioned configuration, a process plan can be created according to the above-mentioned single operation pattern, partial parallel operation pattern, and parallel operation pattern, so that the process plan can be created with high accuracy. Moreover, the process plan can be easily created using the basic data stored in the data storage unit 14, the information on the work progress pattern acquired by the information acquisition unit 11, and the construction information required for creating the process plan.

[0065] In this embodiment, the basic data stored in the data storage unit 14 includes data on standard work time for each process in the water pipe construction work. The work time calculation unit 12 calculates the work time for each process according to the work progress pattern using the data on standard work time.

[0066] This makes it possible to easily calculate the work time for each process of water pipe construction, and therefore the work time according to the work progress pattern can also be easily calculated.

[0067] In this embodiment, the operation time calculation unit 12 calculates a plurality of operation times according to the operation progress pattern using data on the standard operation time. The process plan creation unit 13 creates the process plan using the longest operation time among the plurality of operation times calculated by the operation time calculation unit 12.

[0068] This makes it possible to prevent the work time calculated by the work plan creation device 1 from being shorter than the work time for the actual water pipe construction work. Therefore, it is possible to create a work plan for the water pipe construction work that is feasible with ample time to spare for the progress of the actual water pipe construction work.

[0069] In this embodiment, the work time calculation unit 12 increases the number of water pipes on which the water pipe construction work is to be performed within a predetermined period and calculates the work time for each number of pipes. When the total work time calculated by the work time calculation unit 12 exceeds a specified value, the process plan creation unit 13 creates the process plan based on the work time when the number of water pipes on which the water pipe construction work is to be performed within the predetermined period is reduced by one.

[0070] This makes it possible to easily calculate the process period according to the number of water pipes that can be worked on within a given period (for example, one day), thereby enabling the process plan to be created with greater accuracy.

[0071] In addition, in this embodiment, the work progress pattern includes a work pattern in which each process of excavation, piping, and backfilling in the pipeline construction is carried out independently or at least some of these processes are carried out in parallel.

[0072] This makes it possible to calculate the work time and create a process plan taking into consideration the work progress pattern in each process of excavation, piping, and backfilling in the pipeline construction, thereby making it possible to create the process plan with higher accuracy.

[0073] (Process planning calculation method) Next, a process plan creating method realized by the process plan creating device 1 having the above-mentioned configuration will be described with reference to Fig. 8. Fig. 8 is a flowchart showing an example of the process plan creating method.

[0074] 8 starts, first, the information acquisition unit 11 of the process plan creation device 1 acquires construction information (step S1). The information acquisition unit 11 outputs the acquired construction information to the work time calculation unit 12. The information acquisition unit 11 may acquire the construction information from a design device (not shown), or may acquire the construction information based on an input operation to an input device (not shown).

[0075] Next, the work time calculation unit 12 reads out basic data from the data storage unit 14 (step S2). This basic data includes basic data for construction planning and basic data for materials. In the following step S3, the work time calculation unit 12 calculates the work time for each type of work using the construction information and the basic data.

[0076] Thereafter, in step S4, the information acquisition unit 11 acquires information on the selected work progress pattern. The selection of the work pattern may be performed, for example, by an input operation by a worker, or may be included in the construction information in advance. The work progress patterns include an all-process parallel work pattern, a partial parallel work pattern, and an independent work pattern. The work progress patterns also include patterns in which the lengths of work times for processes are different in the all-process parallel work pattern, the partial parallel work pattern, and the independent work pattern.

[0077] The process plan creation unit 13 accumulates the work time calculated by the work time calculation unit 12 according to the selected work progress pattern (step S5). At this time, the process plan creation unit 13 accumulates the work time for laying one water pipe to create a process plan.

[0078] In the next step S6, the process plan creation unit 13 judges whether the accumulated total work time is within the reference time. If the total work time is within the reference time (YES in step S6), the process proceeds to step S7, and the number of water pipes to be laid is increased by one to make it two. Then, in step S5, the work time calculation unit 12 calculates the work time of each process when laying two water pipes, and the process plan creation unit 13 accumulates the work times according to the selected work progress pattern to obtain the total work time. This flow of steps S6, S7, and S5 is performed until it is judged in step S6 that the total work time has exceeded the reference time (NO in step S6).

[0079] If it is determined in step S6 that the total work time has exceeded the reference time (NO in step S6), the process proceeds to step S8, where the process plan creation unit 13 creates a process plan by reducing the number of water pipes to be laid by 1. Then, in step S9, the created process plan is output, and this flow ends (END).

[0080] Here, step S2 corresponds to a data acquisition step, steps S1 and S4 correspond to information acquisition steps, steps S3 and S5 correspond to work time calculation steps, and step S8 corresponds to a process plan creation step.

[0081] The process plan creation method of this embodiment is a method for creating a process plan for water pipe construction by the process plan creation device 1. The process plan creation method includes a data acquisition step (step S2) in which the work time calculation unit 12 of the process plan creation device 1 acquires basic data used for creating the process plan from the data storage unit 14 of the process plan creation device 1, an information acquisition step (steps S1, S4) in which the information acquisition unit 11 of the process plan creation device 1 acquires information on the work progress pattern in the water pipe construction and construction information necessary for creating the process plan, a work time calculation step (steps S3, S5) in which the work time calculation unit 12 calculates a work time according to the work progress pattern using the basic data acquired in the data acquisition step and the information acquired in the information acquisition step, and a process plan creation step (step S8) in which the process plan creation unit 13 of the process plan creation device 1 creates the process plan based on the work time calculated in the work time calculation step.

[0082] This realizes a method for calculating work time according to a work progress pattern in water pipe construction and creating a process plan according to the work progress pattern. This method allows the process plan to be created with high accuracy. Moreover, this method allows the process plan to be easily created using the basic data acquired in the data acquisition step, the information related to the work progress pattern acquired in the information acquisition step, and the construction information required for creating the process plan.

[0083] (A program for creating process plans) The program in the embodiment of the present invention may be a program that causes a computer constituting the process plan creation device 1 to execute steps S1 to S9 shown in Fig. 8. The process plan creation device 1 and the process plan creation method in this embodiment can be realized by executing this program by the computer of the process plan creation device 1. In this case, the computer constituting the process plan creation device 1 may be a general-purpose computer or a dedicated computer. The computer is equipped with, for example, a CPU, and performs arithmetic processing by the CPU (Central Processing Unit).

[0084] In this embodiment, the data acquired by the process plan creation device 1 and the calculation results are stored in a data storage unit 14. When the process plan creation device 1 performs calculations using the data stored in the data storage unit 14, the process plan creation device 1 reads the data and performs calculation processing. The data storage unit 14 is configured with a storage medium including a storage device such as a memory, a hard disk, etc.

[0085] The program for creating a process plan for water pipe construction according to this embodiment is a program for creating a process plan for water pipe construction. This program causes a computer to obtain basic data used for creating the process plan from the data storage unit 14, obtain information on the work progress pattern in the water pipe construction and construction information required for creating the process plan, calculate a work time according to the work progress pattern using the basic data and the obtained information, and create the process plan based on the calculated work time.

[0086] This makes it possible to realize a program that can calculate work time according to the work progress pattern in pipeline construction and create a process plan according to the work progress pattern. By executing this program, a process plan can be created with high accuracy. Moreover, the program makes it possible to easily create a process plan using basic data, information related to the work progress pattern, and construction information required for creating the process plan.

[0087] [Embodiment 2] (Water pipe construction process planning system) 9 is a functional block diagram showing a schematic configuration of a process plan creation system 100 according to a second embodiment of the present invention. The process plan creation system 100 creates and outputs a process plan for water pipe construction. The process plan creation system 100 includes a server 101 and an input terminal 102.

[0088] The server 101 is configured to be able to communicate with the input terminal 102, and creates a process plan based on information input to the input terminal 102. In detail, the server 101 has an operation time calculation unit 112, a process plan creation unit 113, a data storage unit 114, and a server-side communication unit 115. Note that the operation time calculation unit 112 and the process plan creation unit 113 have the same functions as the operation time calculation unit 12 and the process plan creation unit 13 of the first embodiment, respectively, and therefore detailed description thereof will be omitted.

[0089] The data storage unit 114 stores the same basic data as in the first embodiment, and also stores information acquired from the terminal side communication unit 123 of the input terminal 102 by the server side communication unit 115. The information includes, for example, work progress information and construction information.

[0090] The server-side communication unit 115 is configured to be able to transmit and receive information to and from the terminal-side communication unit 123 of the input terminal 102. Specifically, the server-side communication unit 115 receives work progress information and construction information from the terminal-side communication unit 123 of the input terminal 102, while transmitting process plan information related to the process plan to the terminal-side communication unit 123 of the input terminal 102.

[0091] The input terminal 102 has an input unit 121, a control unit 122, and a terminal side communication unit 123. The input unit 121 acquires information through an input operation by an operator. The input unit 121 may be, for example, a device capable of input operation such as a keyboard, a device that acquires information stored in a medium, or a device that acquires information from the outside through communication or the like. The information acquired by the input unit 121 is input to the control unit 122. The input unit 121 may have any configuration as long as it is capable of inputting information to the control unit 122 of the input terminal 102.

[0092] The control unit 122 transmits the information input to the input unit 121 to the server side communication unit 115 of the server 101 via the terminal side communication unit 123. The control unit 122 also processes the information transmitted from the server side communication unit 115 to the terminal side communication unit 123. The control unit 122 may, for example, output the information received by the terminal side communication unit 123 to an output device (not shown).

[0093] The terminal-side communication unit 123 is configured to be able to transmit and receive information to and from the server-side communication unit 115 of the server 101. Specifically, the terminal-side communication unit 123 transmits work progress information and construction information to the server-side communication unit 115 of the server 101, while receiving process plan information related to the process plan from the server-side communication unit 115 of the server 101.

[0094] As described above, the water pipe construction work schedule creation system 100 according to the present embodiment includes an input terminal 102 and a server 101 capable of communicating with the input terminal 102, and is a system for creating a water pipe construction work schedule. The input terminal 102 includes an input unit 121 for inputting information on the work progress pattern in the water pipe construction work and construction information required for creating the work plan, and a terminal side communication unit 123 for transmitting the information input to the input unit 121 to the server 101. The server 101 includes a server side communication unit 115 for receiving the information transmitted from the terminal side communication unit 123, a data storage unit 114 in which basic data used for creating the work plan is stored and in which the information received by the server side communication unit 115 is stored, a work time calculation unit 112 for calculating a work time according to the work progress pattern using the basic data and the information stored in the data storage unit 114, and a work plan creation unit 113 for creating the work plan based on the work time calculated by the work time calculation unit 112.

[0095] This makes it possible to calculate the work time according to the work progress pattern in water pipe construction and to create a process plan according to the work progress pattern. The work progress pattern includes, for example, a single work pattern in which one team performs each process of excavation, piping, and backfilling in order, a partial parallel work pattern in which multiple teams perform the excavation and piping processes in parallel among the above processes, while all the teams perform the backfilling, and a parallel work pattern in which multiple teams perform all the above processes in parallel.

[0096] With the above-mentioned configuration, a process plan can be created according to the above-mentioned single operation pattern, partial parallel operation pattern, and parallel operation pattern, so that the process plan can be created with high accuracy. Moreover, the process plan can be easily created using the basic data stored in the data storage unit 114, information related to the work progress pattern, and construction information required for creating the process plan.

[0097] In this embodiment, the basic data stored in the data storage unit 114 includes data on standard work time for each process in the water pipe construction work. The work time calculation unit 112 uses the data on standard work time to calculate the work time for each process according to the work progress pattern.

[0098] This makes it possible to easily calculate the work time for each process of water pipe construction, and therefore the work time according to the work progress pattern can also be easily calculated.

[0099] (Other embodiments) Although the embodiment of the present invention has been described above, the above-mentioned embodiment is merely an example for carrying out the present invention. Therefore, the present invention is not limited to the above-mentioned embodiment, and it is possible to carry out the above-mentioned embodiment by appropriately modifying it within the scope of the gist of the present invention.

[0100] In the first embodiment, if the total work time falls within the reference time, the process plan creation unit 13 increases the number of water pipes to be laid by one, causes the work time calculation unit 12 to calculate the laying work time, and calculates the total work time for N+1 pipes using the result. If the total work time does not fall within the reference time, the process plan creation unit 13 creates and outputs a process plan for laying water pipes that are one less (N-1 pipes) than the N pipes for which the total work time was calculated.

[0101] However, the process plan creation unit may calculate the total work time for a predetermined number of N water pipes, and if the total work time is not within the reference time, reduce the number of water pipes until the total work time falls within the reference time. In this case, the process plan creation unit creates and outputs a process plan for laying a number of water pipes corresponding to the total work time falling within the reference time.

[0102] In the first embodiment, the information acquisition unit 11 acquires work progress information and construction information. However, the information acquisition unit may acquire information other than the work progress information and construction information.

[0103] In the first embodiment, the data storage unit 14 stores basic data. However, the data storage unit may store information acquired by the information acquisition unit, or may store data other than the basic data. The data storage unit may store data on the operation time calculated by the operation time calculation unit, data on the total operation time calculated by the process plan creation unit, or data on the process plan created by the process plan creation unit.

[0104] In the second embodiment, the input unit 121 of the input terminal 102 acquires work progress information and construction information. However, the input unit may acquire information other than the work progress information and construction information.

[0105] In the second embodiment, the server 101 has the data storage unit 114. However, the input terminal may have the data storage unit. In this case, the basic data and the like stored in the data storage unit are transmitted from the terminal-side communication unit of the input terminal to the server-side communication unit of the server.

[0106] In each of the above-described embodiments, the work progress patterns include an all-process-parallel work pattern, a partially parallel work pattern, an independent work pattern, and the like, and also include patterns in which the work time of each process is different in the all-process-parallel work pattern, the partially parallel work pattern, and the independent work pattern. However, the work progress patterns may also include patterns in which the order of processes is changed. [Industrial Applicability]
