DETAILED DESCRIPTION OF THE INVENTION

[0010] Hereinafter, a work efficiency improvement support method and a work efficiency improvement support program according to an embodiment of the present invention will be described with reference to the drawings.

[0011] The work efficiency improvement support method and work efficiency support program according to the embodiments of the present invention are support tools for improving work efficiency in construction work, and for example, calculate the work status of construction work when constructing a structure 1 such as that shown in FIG. 1 in accordance with preset conditions.

[0012] The following describes, with reference to Figures 1 to 13, a case in which construction work for which the work status is calculated by the work efficiency improvement support method and work efficiency support program is the installation of formwork for a concrete structure 1 as shown in Figure 1, for example, when constructing the foundation skeleton of a building. Figure 2 is a flowchart showing the steps executed by the work efficiency improvement support method, Figures 3 to 12 are diagrams for explaining the conditions that are set in advance, and Figure 13 is a diagram showing an example of a simulation performed by the work efficiency improvement support method.

[0013] The structure 1 is not limited to a concrete foundation skeleton, which has a relatively simple shape, but may be, for example, a building such as an apartment house, or a structure such as a dam or a bridge. In the following description, three mutually orthogonal axes X, Y, and Z shown in Fig. 1 are set, with the X axis being horizontal and extending in the direction in which the pair of walls 2a and 2b extend, the Y axis being horizontal and extending in the direction orthogonal to the X axis (the direction in which the pair of walls 2c and 2d extend), and the Z axis being vertical.

[0014] The work efficiency improvement support method is executed in accordance with the control flow shown in Figure 2 by starting a work efficiency improvement support program that has been stored in advance in a ROM or the like in a computer (not shown) having general computing functions and including a CPU (Central Processing Unit), ROM (Read Only Memory), RAM (Random Access Memory), and an I / O interface (Input / Output Interface).

[0015] When the work efficiency improvement support program is started, first, in step S11, design data of the structure 1 that is the target of the construction work is acquired (target data acquisition step).

[0016] Specifically, three-dimensional shape data of the structure 1 in a three-dimensional coordinate system with the above-mentioned X-axis, Y-axis, and Z-axis as coordinate axes is acquired as design data. The design data of the structure 1 may be acquired by downloading BIM (Building Information Modeling) or CIM (Construction Information Modeling), which is three-dimensional shape data of a building, via a network such as the Internet. Note that the design data of the structure 1 acquired in step S11 is not limited to three-dimensional shape data and may be two-dimensional shape data, in which case the three-dimensional shape data is generated from the acquired two-dimensional shape data of the structure 1.

[0017] Once the three-dimensional shape data of the structure 1 has been acquired, in the following step S12, area conditions relating to the work area where the work of constructing the structure 1 will be carried out are acquired (area condition acquisition step).

[0018] Specifically, as area conditions, no-entry areas NE1 and NE2 where workers are prohibited from entering and passages ST1 and ST2 through which workers can move are set in advance within the work area, as shown in Fig. 3. The no-entry areas NE1 and NE2 are, for example, areas where construction machinery and vehicles pass through or are placed, or areas where a material storage area M (described later) is set up, and the passages ST1 and ST2 are, for example, temporary stairs for climbing over walls 2a and 2b to move around.

[0019] As shown in FIG. 4, a plurality of work locations A to H where construction work for constructing the structure 1 is carried out are set within the work area as area conditions.

[0020] In the example shown in FIG. 4, a plurality of work locations A to H are set up where work of installing panels (formwork) to be used when constructing the concrete structure 1 is carried out.

[0021] Specifically, a plurality of work positions A1-A7 are set on the inside of the first wall 2a where panels that form the inner surface of the first wall 2a are installed, and a plurality of work positions E1-E7 are set on the outside of the first wall 2a opposite to these where panels that form the outer surface of the first wall 2a are installed. Similarly, a plurality of work positions B1-B7, F1-F7 are set on the inside and outside of the second wall 2b, a plurality of work positions C1-C7, G1-G7 are set on the inside and outside of the third wall 2c, and a plurality of work positions D1-D7, H1-H7 are set on the inside and outside of the fourth wall 2d.

[0022] A work order in which work content (described later) is performed and a distribution order in which materials (described later) are distributed are set for the multiple work locations A to H set up in this way. These orders are set, for example, starting from the left end of the first wall 2a shown in Fig. 4, in the order of the third wall 2c, the second wall 2b, and the fourth wall 2d in a counterclockwise direction from the first wall 2a. Note that these orders can be set arbitrarily, and may be set, for example, in alphabetical order of the symbols assigned to each work location and in ascending numerical order, or the work order and the distribution order may be set separately.

[0023] Furthermore, a coordinate position is set for each of the work locations A to H, and information such as the length and area in each axis direction is also set.

[0024] 4 is an example, and is not limited to this setting. Opposite work areas, for example, work areas A1 to A7 and work areas E1 to E7, may be integrated into one work area, or one work area A1 may be further divided into multiple work areas. Furthermore, the work areas may be divided not only in the horizontal direction (X-axis direction and Y-axis direction) but also in the vertical direction (Z-axis direction).

[0025] Once area conditions are acquired, including multiple work locations where construction work will be performed by workers, passageways through which workers can move, areas where workers are prohibited from entering, etc., work conditions relating to the work process to be carried out at the work locations are acquired in the following step S13 (work condition acquisition step).

[0026] The work conditions include the work content that constitutes the work process performed at each work location, the materials required for the work content, the conditions under which the work content is started, and the work rate for the work content.

[0027] Specifically, as shown in Figure 5, for example, in the "laying battens" task of laying battens that form the base of a panel, battens are set as a required material, and the distribution of the battens is set as a start condition for the task. The number of workers required to perform the "laying batten" task and the work rate P1 are set as work conditions. The work rate P is generally a numerical representation of the amount of work required depending on the type of work, etc., and indicates the amount of work that one worker can perform in a unit of time (e.g., one second, one minute, one hour, one day (8 hours), etc.) in units of one man-hour. In other words, a smaller value for the work rate P indicates a relatively difficult task, i.e., a task with relatively poor workability, while a larger value for the work rate P indicates a relatively easy task, i.e., a task with relatively good workability. The work rate P1 set for the "laying battens" work is the range of battens that one worker can lay per unit time (for example, 1 second, 1 minute, 1 hour, 1 day (8 hours), etc.), and can be expressed as, for example, length (m) or area (m 2 ) is shown.

[0028] Similarly, for work tasks such as "panel installation," "form tie (registered trademark, omitted hereafter) installation," "vertical batten installation," "horizontal batten installation," and "form tie fixing" that are required in general formwork installation work, the necessary materials, the conditions for starting the work task, the number of workers required to perform the work, and the work rates P2 to P6 that indicate the amount of work that one worker can perform in a unit of time (for example, one second, one minute, one hour, one day (8 hours), etc.) are set as work conditions.

[0029] For example, in the panel installation process, if the installation of separators is included (process 2-1), the panels and separators are the required materials, so the conditions for starting work are that process 1 is completed and the panels and separators have been distributed; and if the installation of separators is not included (process 2-2), only the panels are the required materials, so the conditions for starting work are that process 1 is completed and the installation of panels (process 2-1), including the installation of separators, has been completed at the opposite work location and the panels have been distributed.

[0030] Furthermore, since the form tie fixing process generally requires that the distance between opposing panels be a specified size, the condition for starting work is that once the work of installing the horizontal battens is completed, it becomes possible to simultaneously carry out the form tie fixing work at the opposing work location, i.e., workers must also be stationed at the opposing work location.

[0031] By combining the preset work contents in this way, a work process to be performed at each of the work locations A, B, C, D, E, F, G, and H is set, as shown in Fig. 6. In the example shown in Fig. 6, at the work locations A, B, C, and D set inside each wall 2, the work contents shown in Fig. 5 are performed in the order of step 1, step 2-1, step 3, step 4, step 5, and step 6, and at the work locations E, F, G, and H set outside each wall 2, the work contents shown in Fig. 5 are performed in the order of step 1, step 2-2, step 3, step 4, step 5, and step 6. Note that the work contents that make up a work process are not limited to these, and other work contents may be added as appropriate. Furthermore, the order in which the work contents are performed is merely an example and is not limited to the above order.

[0032] After the work conditions are acquired in step S13, material conditions relating to materials to be used in the work process are acquired in the following step S14 (material condition acquisition step).

[0033] The material conditions include the location of the material storage area where the material is stored, the conditions under which the material is transported, and the rate of transportation of the material.

[0034] 7, the material storage areas M are set up as a primary material storage area M1 located relatively far from the work location, i.e., the structure 1, and multiple secondary material storage areas M2-M4 located relatively close to the work location and for temporarily receiving materials transported from the primary material storage area M1. The coordinates of the installation location and the maximum storage capacity for each material are set for each of these material storage areas M1-M4.

[0035] As shown in Figure 8, the means for transporting materials from the primary material storage area M1 to the secondary material storage areas M2 to M4 and the means for transporting materials from the secondary material storage areas M2 to M4 to each work location A, B, C, D, E, F, G, and H are also set in advance.

[0036] 7 and 8, among the secondary material storage areas M2-M4, materials are transported by workers from the inner storage area M2 located inside each wall 2 to work areas A, B, C, and D inside each wall 2, materials are transported by workers from the first outer storage area M3 located outside each wall 2 to work areas E and G outside each wall 2, and materials are transported by workers from the second outer storage area M4 located outside each wall 2 to work areas F and H outside each wall 2, and materials are transported by a delivery machine or workers from the primary material storage area M1 to each of the secondary material storage areas M2-M4. Note that, as described above, the installation of separators is set to be performed at work areas A, B, C, and D inside each wall 2, so that separators are transported from the primary material storage area M1 only to the inner storage area M2 located inside each wall 2.

[0037] The material storage areas are not limited to those consisting of a primary material storage area M1 and secondary material storage areas M2 to M4, and only the primary material storage area M1 may be provided and materials may be transported directly from the primary material storage area M1 to each work location, or an intermediate material storage area may be provided between the primary material storage area M1 and the secondary material storage areas M2 to M4. Furthermore, the locations of the secondary material storage areas M2 to M4 do not need to be always the same, and may be set to change as the work progresses.

[0038] The delivery machines that transport materials from the primary material storage area M1 to the secondary material storage areas M2 to M4 are, for example, cranes and forklifts. A crane is set as the delivery machine for transporting materials to a material storage area that is located in a place where vehicles cannot enter from the outside, such as the inner storage area M2, and a crane or forklift is set as the delivery machine for transporting materials to material storage areas that are located on the same plane as the primary material storage area M1, such as the first outer storage area M3 and the second outer storage area M4. Note that the delivery machines are not limited to cranes and forklifts, and may be any type of work machine that is capable of transporting the above-mentioned materials. Furthermore, relatively small materials such as separators and form ties may be transported by workers.

[0039] The conditions under which materials are transported and the rate of transport of materials are set according to the transport route and transport means, as shown in FIGS.

[0040] 9 shows the transport quantity, transport rate, and transport conditions (first transport conditions) when each material is transported by a delivery machine from the primary material storage area M1 to each of the secondary material storage areas M2 to M4. Note that when relatively small materials such as separators and form ties are transported by workers from the primary material storage area M1 to each of the secondary material storage areas M2 to M4, the transport quantity, number of transporters, transport rate, and transport conditions for these materials are set separately.

[0041] Specifically, the amount of slats that can be transported by a single delivery operation of a delivery machine is the transport quantity N1, and the distance (m) that one delivery machine can transport this transport quantity N1 in a unit of time (for example, 1 second, 1 minute, 1 hour, 1 day (8 hours), etc.) is set as the transport unit rate TPM1. Similarly, transport quantities N2 to N6 and transport units TPM2 to TPM6 are set for other materials, respectively. Furthermore, for materials other than slats that are initially transported to each of the secondary material storage areas M2 to M4, conditions are set for permitting the transport of materials to each of the secondary material storage areas M2 to M4; for example, panels are permitted to be transported when the progress of work on process 1 (laying slats) at the work site exceeds a predetermined value X1% (for example, 20%).

[0042] In addition, which of the multiple secondary material storage areas M2 to M4 will be given priority for transportation is set according to the work locations A to H corresponding to each secondary material storage area M2 to M4, and specifically, is set in accordance with the distribution order of materials to the work locations A to H included in the area conditions obtained in step S12 above.

[0043] In addition, if a crane is set up on the delivery machine, the condition for starting transportation is that workers with the skills of rigging workers have arrived at both the primary material storage area M1 from which the materials are being delivered and the secondary material storage areas M2 to M4 where the materials are being delivered.

[0044] FIG. 10 shows the transport quantity, number of transporters, transport rate, and transport conditions (second transport conditions) when each material is transported by workers from each secondary material storage area M2 to M4 to each work location A to H.

[0045] Specifically, two battens are transported by one worker, and the distance (m) that one worker can transport this number of battens per unit of time (e.g., one second, one minute, one hour, one day (8 hours), etc.) is set as the transport rate TP1. Similarly, the transport rate, number of workers, and transport rates TP2 to TP6 are set for the other materials. In addition, for materials other than the battens that are first transported to each of the work locations A to H, conditions are set for allowing the material to be transported to each of the work locations A to H. For example, panels are permitted to be transported when the progress of work on process 1 (laying battens) at the work location exceeds a predetermined value Y1% (e.g., 50%). The order of the work locations A to H to which the workers transport the materials is included in the area conditions acquired in step S12 above.

[0046] Since the transportation of materials from each secondary material storage area M2 to M4 to each work location A to H is premised on the materials being in stock at each secondary material storage area M2 to M4, in order to ensure that materials are brought in from the primary material storage area M1 to each secondary material storage area M2 to M4 before materials are brought out from each secondary material storage area M2 to M4 to each work location A to H, the progress rate (X1 to X4%) of each process 1 to 4, which serves as the criterion for determining whether materials are needed to be transported from the primary material storage area M1 to each secondary material storage area M2 to M4, is set to a smaller value than the progress rate (Y1 to Y4%) of each process 1 to 4, which serves as the criterion for determining whether materials are needed to be transported from each secondary material storage area M2 to M4 to each work location A to H.

[0047] After the material conditions are acquired in step S14, worker conditions relating to the workers who will be working in the work area are acquired in the following step S15 (worker condition acquisition step).

[0048] The worker conditions include the number of workers who will be working in the work area, the level of proficiency of each worker in the work content, and the skills possessed by each worker.

[0049] For each worker, the coordinate position of the worker at the start of work is set as the initial position, and the skills possessed by each worker are also set, as shown in Fig. 11. The possessed skills are qualifications related to the work, such as a rigging worker, a formwork construction technician, or a forklift driver qualification.

[0050] Furthermore, a proficiency level is set for each worker for the above-mentioned work content (steps 1 to 6). The proficiency level is based on the unit rate for each work content included in the work conditions acquired in step S13 above. A proficiency level greater than 1 means that more work can be done than the set unit rate, while a proficiency level less than 1 means that the amount of work that can be performed is less than the set unit rate. When a task is performed by multiple people, such as installing horizontal battens (step 5), workers are selected from among those who are capable of the task, with an arbitrary range of proficiency levels. It is also possible to set the movement speed and material transport speed for each worker as worker conditions, but the movement speed and transport speed of all workers are set to the same value.

[0051] The worker conditions also include extraction conditions for which workers are selected from among those on standby to perform the work. As shown in Figure 12, multiple extraction conditions are set, and priorities are assigned to these conditions. Changing these conditions and priorities enables various simulations.

[0052] Specifically, workers who have the skills required for the target work process are first hired from among the workers on standby. For example, if the work involves carrying materials into the secondary material storage areas M2 to M4 using a carrying-in machine (crane), a worker with the skills of a rigging worker will be hired.

[0053] If the task does not require specific skills, the process moves to the next extraction condition, where the proficiency levels of the target work process are compared and a worker with high proficiency is hired. By giving priority to workers with high proficiency in this way, it is possible to simulate a situation in which work is performed more efficiently. Note that, in order to simulate a case in which work efficiency is low, hiring a worker with low proficiency may be set as a relatively preferential condition in the extraction conditions.

[0054] In addition, by prioritizing the use of workers with fewer other skills for work and keeping workers with more other skills on standby, it is possible to be in a state where a quick response can be made when work that requires a specific skill arises.

[0055] Furthermore, by prioritizing the use of workers with low total proficiency levels for work and keeping workers with high total proficiency levels on standby, it is possible to ensure that a rapid response can be made when work that requires a small amount of work and is relatively difficult to carry out arises.

[0056] If a worker cannot be selected using these extraction conditions, for example, if the work does not require specific skills and the number of skills and proficiency of the waiting worker are the same, a worker who is closest to the work location of the target work process will be hired.

[0057] The above-mentioned extraction conditions are merely examples and are not limiting. Furthermore, extraction conditions may be set for each process.

[0058] In step S15, worker conditions are acquired, and once all conditions required for executing a simulation have been acquired, in the following step S16, a simulation of the work situation in the work area is carried out (simulation step).

[0059] The simulation of the work situation is performed based on the area conditions, work conditions, material conditions, and worker conditions acquired in steps S12 to S15.

[0060] Specifically, when the simulation begins, first, in order to start process 1 at work location A1, the necessary materials (battens) are transported by a delivery machine from the primary material storage area M1 to the inner storage area M2. Based on the above-mentioned worker conditions, workers with rigging skills are moved in advance between the primary material storage area M1 and the inner storage area M2.

[0061] Next, the necessary materials (battens) are transported (distributed) from the inner storage area M2 to the work area A1. The workers who transport the necessary materials from the inner storage area M2 are set based on the worker conditions described above. At the same time, other workers also transport (distribute) the necessary materials to other work areas, which is a start condition for process 1.

[0062] The shortest route for workers to travel to each of the work locations A-H, secondary material storage locations M2-M4, and primary material storage location M1 is calculated as needed based on the no-entry areas NE1, NE2, etc., set in the area conditions described above. The time required for transportation is calculated by dividing the calculated shortest route by the transportation rate TP, and as a result, the time when work can begin at each work location is determined. For example, if the transportation rate TP is 2.0 m / sec and the shortest route is 100 m, the time required for transportation is 50 seconds.

[0063] Then, when the progress of process 1 at work location A1 exceeds a predetermined value Y1% (e.g., 50%), the transport of necessary materials (panels and separators), which is a start condition for the next process 2-1, is permitted, and if there are workers waiting, the necessary materials are transported (distributed) from the inner storage area M2. Similarly, when the progress of process 1 at other work locations exceeds a predetermined value X%, the necessary materials are transported (distributed) to the other work locations. The work time for process 1 at work location A1 is calculated by dividing the length of work location A1 in the X-axis direction, i.e., the work area, by the work rate P1 for process 1. Note that when the progress of process 1 at work location A1 exceeds a predetermined value X1% (e.g., 20%), panels and separators are transported from the primary material storage area M1 to the inner storage area M2.

[0064] Furthermore, if there are no workers available to distribute the necessary materials (panels and separators) to work location A1, process 2-1 cannot be started at work location A1, so the workers working at work location A1 will move to another work location where process 1 has not yet begun, if there are other work locations where process 1 has not yet begun, and will continue working there, or if there are no other work locations where process 1 has not yet begun, they will move to inner storage area M2 and transport (distribute) the necessary materials (panels and separators) to work location A1.

[0065] In this way, based on the area conditions, work conditions, material conditions, and worker conditions, the necessary materials are transported from the primary material storage area M1 via the secondary material storage areas M2 to M4 to each work location at the required time, and work is carried out sequentially at each work location. The simulation ends when all work processes are completed at all work locations.

[0066] The simulation of the work situation is executed by the CPU of a computer (not shown), and as shown in FIG. 13, the progress can also be displayed as an animation on a monitor screen (not shown).

[0067] Figure 13 shows a situation in which the number of workers is set to six, with the first worker W1 and the second worker W2 working together, the third worker W3 working alone, the fourth worker W4 performing distribution work, the fifth worker W5 performing transport work, and the sixth worker W6 on standby.

[0068] In this way, by visually checking the situation through animation, it is possible to consider the optimal layout of secondary material storage areas M2 to M4 and aisle ST. Also, if work does not progress or is interrupted midway, it is possible to identify any deficiencies in the conditions set for the various conditions mentioned above.

[0069] When the simulation is finished, the work time required to complete all the work is output as the simulation result, and the work breakdown (work, movement, transport, distribution, waiting) of each worker W1 to W6 is also output as shown in Figure 14.

[0070] In this way, by comparing the work breakdowns of the workers W1 to W6, it is possible to grasp the variations in workload in advance, and to consider measures to equalize the workload.

[0071] Also, as shown in FIG. 15, it is possible to compare the results of simulations performed by changing the number of workers, for example.

[0072] In the example shown in Figure 15, changes in task duration, standby rate, and standby time width are graphed when the number of workers is changed. The standby rate is calculated by dividing the total standby time of all workers by the task duration, and a higher value indicates that the worker is in standby mode, i.e., not working. The standby time width is the difference in standby time between workers with long standby times and workers with short standby times, and the larger this difference, the more likely it is that some workers are unable to concentrate on their tasks due to long gaps between tasks.

[0073] Looking at the work period, it becomes shorter as the number of workers increases, but this tendency slows down once a certain number of workers is reached. Looking at the waiting rate and waiting time, it changes depending on the number of workers, and both tend to increase even if the number of workers is increased. Looking at these trends together, it is clear that there is an optimal number of workers.

[0074] In this way, by changing the number of workers and performing a simulation, the optimal number of workers can be determined in advance. Note that the parameters that can be changed are not limited to the number of workers, but may also be, for example, the proficiency and skills of the workers, the number and locations of material storage areas, and the type and number of delivery machines.

[0075] After the above steps, the simulation results are output, and the control flow ends. Note that the order in which the conditions are acquired in steps S12 to S15 is not limited to the above order, and the conditions acquired in steps S12 to S15 may be acquired all at once.

[0076] By simulating the work situation under predetermined conditions in this way, it is possible to predict the work situation and optimize the number of workers and the number and location of material storage areas. Also, by simulating construction work that has already been completed, it is possible to verify whether there were any areas that needed improvement.

[0077] According to the above embodiment, the following effects are achieved.

[0078] According to the above-described work efficiency improvement support method and work efficiency support program, the work situation within the work area is simulated in the simulation step based on the area conditions related to the work area acquired in the area condition acquisition step, the work conditions related to the work process acquired in the work condition acquisition step, the material conditions related to the materials acquired in the material condition acquisition step, and the worker conditions related to the workers acquired in the worker condition acquisition step.

[0079] The work conditions include the work content that makes up the work process, the materials required for the work content, the conditions under which the work content will begin, and the unit rate for the work content; the material conditions include the location of the material storage area where the materials will be placed, the conditions under which the materials will be transported, and the unit rate for transporting the materials; and the worker conditions include the number of workers, so that the work situation within the work area can be accurately simulated.

[0080] This makes it possible to determine the optimal combination of factors such as the number of workers and the location of material storage areas before construction work actually begins, thereby improving work efficiency during construction work.

[0081] Furthermore, by accurately simulating the work situation for construction work that has already been completed, it is possible to compare the actual work situation with the work situation predicted by the simulation and verify whether there are any areas that need improvement, and the verification results obtained can be reflected in future construction work.

[0082] The following modified examples are also within the scope of the present invention, and it is possible to combine the configuration shown in the modified example with the configuration described in the above embodiment, or to combine the configurations described in the different modified examples below.

[0083] In the above embodiment, the construction work to be simulated is the installation of formwork, but the construction work to be simulated is not limited to this and may be, for example, the assembly of scaffolding or shoring, the removal of formwork, or the installation of interior fittings.

[0084] Although the embodiments of the present invention have been described above, the above embodiments merely illustrate some of the application examples of the present invention, and it is not intended that the technical scope of the present invention be limited to the specific configurations of the above embodiments.
