Description

[Technical Field]

[0001] The present disclosure relates to a logistics and process management device, a logistics and process management method, and a program. [Background technology]

[0002] At construction sites, etc., methods of managing materials using tags are being considered. For example, Patent Document 1 considers a method of efficiently managing materials using multiple types of tags. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2006-176281 Summary of the Invention [Problem to be solved by the invention]

[0004] However, materials used in the construction of buildings may require management not only at the manufacturing site but also at the preparation stage. In particular, when buildings are made to order, stricter management may be required.

[0005] The present disclosure has been made in consideration of the above, and aims to provide a technology that enables more appropriate management of materials used in buildings. [Means for solving the problem]

[0006] In order to achieve the above-mentioned object, a logistics and process management device according to one embodiment of the present disclosure is a logistics and process management device that manages the manufacture and logistics of materials used in the construction of a building, and has a tag reading information acquisition unit that acquires tag reading information by reading identification information from multiple different types of tags attached to materials at different stages among multiple work process stages to be managed, and a memory unit that stores, from the tag reading information, each of the identification information of multiple types of tags attached to a specific material in association with the specific material.

[0007] According to the above-described logistics and process management device, materials used in the construction of a building are appropriately managed at different stages among a plurality of work process stages in which work related to the materials is carried out, using different types of tags corresponding to the work process stage. Meanwhile, the memory unit stores the identification information of each of the multiple types of tags attached to a specific material in association with the specific material. Therefore, the management status of a specific material at different work process stages can be appropriately grasped based on the information read from the multiple types of tags. In this way, materials used in the construction can be more appropriately managed.

[0008] The tag reading information may include information specifying the date, time, and location at which the tag was read. When the tag reading information includes information specifying the date, time, and location at which the tag was read, the progress of the work process steps can be grasped in more detail by using the information relating to the date, time, and location at which the tag was read.

[0009] The tag reading information may include information in which identification information of multiple types of tags attached to the material is associated with information specifying a single date and time. As described above, when the tag reading information includes information in which identification information of multiple types of tags attached to the material is associated with information specifying a single date and time, this information can be used to associate tags with each other, making it possible to associate tags with each other easily and reliably, and managing materials appropriately.

[0010] The plurality of work process stages may include a stage for manufacturing the material and a stage for managing the material after manufacturing. When materials are used in a building, it is necessary to properly understand the management status of the material in both the stage related to the manufacturing of the material and the stage for managing the material after manufacturing. By adopting the above configuration, it becomes possible to more appropriately manage the materials used in the building.

[0011] The building may be made to order. When a building is made to order, the number and variety of materials required is large, and the reuse of materials for other buildings is restricted due to the individual orders. Therefore, in order to shorten the construction period and achieve greater profits, more meticulous management is required. Therefore, by using the above-described logistics and process management device, materials can be more appropriately managed, and the manufacturing process of the building itself can also be more appropriately managed. Typical examples of made-to-order buildings include ships, large buildings, and plants. These buildings require a particularly large number of processes, from the stage of manufacturing materials to the stage of installing them in the building. Furthermore, the number and variety of materials required are large, so more meticulous management is required. Therefore, the above-described method is considered to be particularly useful.

[0012] A logistics and process management method according to one embodiment of the present disclosure is a logistics and process management method for managing the manufacture and logistics of materials used in the construction of a building, and includes obtaining tag reading information by reading identification information from multiple different types of tags attached to materials at different stages to be managed, and storing, from the tag reading information, each of the identification information from multiple types of tags attached to a specific material in association with the specific material.

[0013] According to the above-described logistics and process management method, at each of the different stages among the multiple work process stages in which work related to materials for constructing a building is performed, materials are appropriately managed using different types of tags corresponding to the work process stage. Meanwhile, among the tag read information, each of the identification information of the multiple types of tags attached to a specific material is stored in association with the specific material. Therefore, the management status of a specific material at each of the different work process stages can be appropriately grasped based on the information read from the multiple types of tags. In this way, materials used in a building can be more appropriately managed.

[0014] A logistics and process management program according to one embodiment of the present disclosure is a logistics and process management program for causing a computer to function as a logistics and process management device for managing the manufacture and logistics of materials used in the construction of a building, and includes a tag reading information acquisition function for acquiring tag reading information by reading identification information from multiple different types of tags attached to materials at different work process stages to be managed, and a storage function for storing, from the tag reading information, each of the identification information from multiple types of tags attached to a specific material in association with the specific material.

[0015] According to the above-described logistics and process management program, materials are appropriately managed at each of the different stages among the multiple work process stages where work related to materials for constructing a building is performed, using different types of tags depending on the work process stage. Furthermore, among the acquired tag read information, each of the identification information of the multiple types of tags attached to a specific material is stored in association with the specific material. Therefore, the management status of a specific material at each of the different work process stages can be appropriately grasped based on the information read from the multiple types of tags. In this way, the management of materials used in a building can be more appropriately performed. [Effects of the Invention]

[0016] According to the present disclosure, a technology is provided that enables more appropriate management of materials used in construction. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0018] Hereinafter, the embodiments will be described in detail with reference to the drawings. In the description, the same elements or elements having the same functions are denoted by the same reference numerals, and redundant description will be omitted.

[0019] (Logistics / process control equipment) FIG. 1 is a diagram schematically illustrating the use of a logistics and process control device 1 according to one embodiment. The logistics and process control device 1 shown in FIG. 1 is a device for managing materials used in, for example, the manufacture of a building. All elements related to logistics and processes included in the entire supply chain, from the procurement of materials to the manufacture of a building using those materials, can be managed. Specifically, the logistics and process control device 1 can manage, for example, procurement logistics related to the procurement of materials from suppliers, etc.; manufacturing logistics related to the management of procured materials and the flow of materials at the manufacturing site of the building, etc.; the manufacture of the materials themselves; the manufacture of the building; and various work processes that occur in connection with logistics. There are no particular limitations on the type of building. The logistics and process control device 1 is particularly useful for managing materials related to the manufacture of custom-made buildings, such as ships, large buildings, and plants. Custom-made buildings are not intended to be built in multiples, but are individually designed and constructed in response to individual orders. Therefore, it is often considered that the reuse of materials for other buildings is restricted.

[0020] Among individually made-to-order structures, large structures such as ships often use a wide variety of materials. Furthermore, materials that have already been partially processed, for example, at a parts manufacturing factory, are often brought to such sites. However, the materials used at such sites are generally so-called custom-made products ordered individually based on specifications or blueprints, and each must be managed individually. At manufacturing sites that handle such a wide variety of materials, delays in the procurement of some materials can affect the manufacturing process of structures such as ships. In response to this, the logistics and process management system 1 is a system that performs centralized management, for example, from the design stage to the installation of materials on the structure, when manufacturing a structure that handles a wide variety of materials. Furthermore, the logistics and process management system 1 can also manage when each manufacturing process that may occur from the design stage to the installation stage on the structure is completed. Therefore, various analyses can be performed based on this information.

[0021] For example, Figure 1 shows piping material X to be installed on a ship as one of the materials. Figure 1 also shows a series of steps involved in the manufacturing process of piping material X and the process of installing it on a ship. In Figure 1, the manufacturing process of piping material X involves, for example, manufacturing steel pipe X1 based on design specification X0, and then galvanizing it to create plated pipe X2. This plated plated pipe X2 is delivered to a shipyard and stored after inspection. When piping material X (plated pipe X2) is actually used in shipbuilding, the piping material is removed from a storage location such as a warehouse, and the piping materials are sorted onto management material pallets for each installation location. The management material pallets are then transported to a predetermined location, where the piping materials are removed from the management material pallets and installed in the predetermined installation locations. This completes the installation of the piping material on the ship.

[0022] This series of steps can be performed for each of a plurality of materials. However, conventionally, there has been a problem in that the manufacturing process of materials and the process of installation on a ship have not been managed in an integrated manner. In response to this, the logistics and process management device 1 can realize a function of managing the entire process from the design stage to installation of materials in an integrated manner, while acquiring information on the progress and required time of each process.

[0023] Next, each unit of the logistics / process control device 1 will be described with reference to Fig. 2. The logistics / process control device 1 has an information registration unit 10, an analysis / output unit 20, and a storage unit 30. The information registration unit 10 is configured to include a tag information acquisition unit 11 and a tag reading information acquisition unit 12, and the analysis / output unit 20 is configured to include an output instruction acquisition unit 21 and an output unit 22.

[0024] The information registration unit 10 has a function of acquiring and registering information related to materials from an external device or the like. In FIG. 2, a terminal device 5 held by a material handler is shown as an example of an external device. The terminal device 5 may be, for example, a smartphone or a tablet terminal device. As an example, FIG. 2 shows three terminal devices 5, but this number can be changed depending on the number of processes for the material, etc.

[0025] The terminal device 5 is configured to be able to read tags attached to materials and transmit the information to the logistics / process management device 1. Therefore, the terminal device 5 may include, for example, a tag reading unit 51 and a communication unit 52. Note that "reading a tag" corresponds to reading identification information that can individually identify a tag. By reading a tag, the identification information of the tag can be obtained. In other words, reading a tag corresponds to identifying an individual tag.

[0026] As will be described in detail later, different types of tags are used for each management stage of materials. The method for reading identification information often differs depending on the type of tag. Therefore, the function of the tag reader 51 may differ depending on the use situation of the terminal device 5. The communication unit 52 is not particularly limited as long as it can transmit information to the logistics and process management device 1. For example, the communication unit 52 may have a function that enables wireless communication. As an example, the terminal device 5 may be configured as a different terminal when the management stage of materials is different. In this case, a tag reading operation performed by a specific terminal device 5 can be treated as the material to which the tag is attached having passed through a specific management stage. However, the present invention is not limited to this configuration.

[0027] The tag information acquisition unit 11 of the information registration unit 10 has a function of acquiring identification information of tags attached to materials from the terminal device 5 or the like. As will be described in detail later, tags are attached to individual materials (each material). Different types of tags may be attached to some of the processes to be managed for the materials (e.g., processes from material manufacturing to material attachment). The tag information acquisition unit 11 acquires in advance the types of tags to be attached to the materials in each process to be managed and stores them in the memory unit 30. At this time, information specifying the timing of the tag reading operation (e.g., reading the tag when the material is inspected) may also be acquired. In this case, by determining the timing of the tag reading operation, information regarding the timing of a specific operation performed on the material can be obtained. The information acquired by the tag information acquisition unit 11 may be provided from a device or the like handled by a person other than the material handler. For example, if the tags to be used for the materials are predetermined, the tag information acquisition unit 11 of the information registration unit 10 may acquire the tag information in advance and register it in the logistics / process management device 1.

[0028] The tag reading information acquisition unit 12 of the information registration unit 10 has a function of updating the information stored in the storage unit 30 when, for example, information (identification information) read from a tag is acquired from the terminal device 5. The terminal device 5 is used when a material handler attaches a tag to a material, removes the tag, or performs a specific process on the material. Specifically, the tag is read by the tag reading unit 51 of the terminal device 5, and the information read by the communication unit 52 is transmitted to the logistics and process management device 1, where it is received. When the tag reading information acquisition unit 12 of the information registration unit 10 acquires information transmitted from the terminal device 5 by reading the tag, it updates the tag reading result. In other words, it updates the information stored in the storage unit 30.

[0029] The analysis and output unit 20 has a function of performing analysis based on the information stored in the memory unit 30 or taking action related to the output of the information stored in the memory unit 30. The output instruction acquisition unit 21 of the analysis and output unit 20 has a function of acquiring output instructions from an external device, etc. The instructions acquired by the output instruction acquisition unit 21 may include instructions related to analysis. The output unit 22 of the analysis and output unit 20 has a function of preparing and outputting information to be output in accordance with the instructions acquired by the output instruction acquisition unit 21. The output destination of the output unit 22 is not particularly limited, and one example is output to a device that sent the output instruction acquired by the output instruction acquisition unit 21. Alternatively, for example, the logistics and process management device 1 may be configured to output based on the output instruction to a display device (monitor), printing device (printer), etc. connected to the logistics and process management device 1.

[0030] The storage unit 30 has a function of storing information acquired by the information registration unit 10. The storage unit 30 is cloud-based on the Internet, and has a function of being readable anytime, anywhere.

[0031] The functions of the logistics and process control device 1 for achieving the above configuration will now be described with reference to FIG. 3. Similar to FIG. 1, FIG. 3 also illustrates the process of manufacturing pipes and installing them on a ship. In the example shown in FIG. 2, eight stages can occur when preparing a design specification for manufacturing pipes, manufacturing the pipes based on the design specification, and installing the manufactured pipes on a ship. Specifically, these stages include T1 (when the design specification (pipe individual product drawing) is created), T2 (when the steel pipe is completed), T3 (when the pipe is received at the plating factory), T4 (when the plating is completed), T5 (when the shipyard inspects and receives the pipes), T6 (when the sorting in the warehouse is completed), T7 (when the pipes are transported to the site), and T8 (when the pipes are installed). By reading tags attached to the design specification, steel pipes, plated pipes, baskets, work ledgers, etc. at these stages, information regarding the current stage of the process (whether the pipes are currently being manufactured or have already been installed on a ship) is sent to the logistics and process control device 1.

[0032] Furthermore, in the example shown in FIG. 3, different tags may be used at different stages of the work process. For example, a barcode is used for the design document X0, a perforated tag is used for the steel pipe X1, and an RFID (Radio Frequency Identification) tag is used for the plated pipe X2 after plating. Thus, even when managing specific materials, different types of tags may be used throughout the process. The reason for adopting this configuration is that tags suitable for different tasks may vary depending on the material manufacturing stage and the work process stage. For example, tags highly resistant to heat and chemical treatments may be used in the steel pipe manufacturing and plating stages. When multiple types of tags are used for a single material, it is possible to obtain the relationship between tags used in the previous and subsequent processes while the same tag is attached. Therefore, a process may be defined as one in which both tags used in the previous and subsequent processes are present, such as elapsed times T2 and T4. By obtaining the identification information of both types of tags attached to a specific material, the process may be associated. At elapsed times T2 and T4, the tag from the previous process is removed and the tag from the next process is attached, respectively. At this time, both tags can be read.

[0033] It is not necessary for multiple types of tags to be attached to a particular material at the same time; it is sufficient that tags are attached to a particular material to the extent that different tags used in multiple processes can be identified.

[0034] Note that Figure 3 shows a tagger (a person who attaches / removes tags, reads tags, etc.). As shown in Figure 3, the tagger may change depending on the production stage of the material. Therefore, each tagger may have a different terminal device 5. Furthermore, each terminal device 5 may have some different functions.

[0035] Fig. 4 shows an example of tag-related information D1, which is information stored in storage unit 30 when work is performed according to the above-mentioned flow. In Fig. 4, one line of tag-related information D1 is used for one material, and when a tag is read at each timing of elapsed time T1, T2, ..., the ID of the read tag and the date and time of tag reading are stored in association with each other in storage unit 30.

[0036] For example, for material No. 1, it is shown that at elapsed time T1, a tag with an ID of DD500 was read. Furthermore, at elapsed time T2, it is shown that two tags, a tag with an ID of DD500 and a tag with an ID of TT01, were read. Of these, the tag with the ID of DD terminal device 500 is, for example, a tag (barcode) linked to a design document, and the tag with the ID of TT01 is, for example, a perforated tag used for steel pipes. In this way, at elapsed time T2, both tags for the previous process and the next process are read. Therefore, the tags for these two processes are stored in the memory unit 30 in an associated state.

[0037] Furthermore, in the example shown in FIG. 4, since the tag with ID D1 corresponds to material No. 1, the tag with ID TT01 is also associated with material No. 1. As shown in FIG. 4, by accumulating tag information for each process as the process progresses, tags related to the same material can be stored in an associated state in the storage unit 30. Furthermore, when stored in this state, it is possible to extract, for example, the required time between processes for a specific material. For example, for material No. 1, tags are read up to elapsed time T5, so it is possible to extract the time required for a specific elapsed time up to elapsed time T5. While the example shown in FIG. 4 is merely an example, by storing tags that are changed depending on the progress of the process in the storage unit 30 in an associated state, it is possible to perform material-related aggregation, etc. Furthermore, depending on the material aggregation method, it is possible to determine the amount of material that has progressed (is progressing) in a process within a specified time period and the extent of stagnation (the state in which materials are stagnating at a specific work stage).

[0038] (Logistics and Process Management Program) An information program for causing a computer to function as the logistics and process management device 1 of this embodiment will be described. Fig. 5 is a diagram showing the configuration of the logistics and process management program P1. In other words, the logistics and process management program P1 is a logistics and process management program for causing a computer to function as a logistics and process management device that manages the production and logistics of materials used in the construction of a building, and includes a tag read information acquisition function that acquires tag read information by reading identification information from multiple different types of tags attached to materials at different stages among multiple work process stages to be managed, and a storage function that stores, from the tag read information, each piece of identification information from multiple types of tags attached to a specific material in a state associated with the specific material.

[0039] The logistics and process control program P1 includes a main module m10 that controls the overall processing of the logistics and process control apparatus 1, an information registration module m11, an analysis and output module m12, and a storage module m13. The main module m10 to the storage module m13 implement the functions of the information registration unit 10, the analysis and output unit 20, and the storage unit 30 in the logistics and process control apparatus 1. The logistics and process control program P1 may be transmitted via a transmission medium such as a communication line, or may be stored in a storage medium M1 as shown in FIG. 5.

[0040] (Hardware configuration) The logistics and process control device 1 is realized by any combination of hardware and / or software. Each function may be realized by a single device that is physically and / or logically coupled, or may be realized by two or more devices that are physically and / or logically separated and directly and / or indirectly connected to each other.

[0041] 6 is a diagram showing an example of the hardware configuration of the logistics / process control apparatus 1. The logistics / process control apparatus 1 may be physically configured as a computer device including a processor 1001, a memory 1002, a storage 1003, a communication device 1004, an input device 1005, an output device 1006, a bus 1007, etc.

[0042] The processor 1001 controls the entire computer by running, for example, an operating system. The processor 1001 may be configured as a central processing unit (CPU). For example, various processes of the logistics and process control apparatus 1 may be implemented by the processor 1001. The processor 1001 also reads programs (program codes), software modules, and data from the storage 1003 and / or the communication device 1004 into the memory 1002 and executes various processes in accordance with these. The functions of executing various processes of the logistics and process control apparatus 1 may be implemented by a control program stored in the memory 1002 and running on the processor 1001, or may be similarly implemented for other functional blocks. Note that various processes in the logistics and process control apparatus 1 may be executed by one processor 1001, or may be executed simultaneously or sequentially by two or more processors 1001.

[0043] The memory 1002 is a computer-readable recording medium and may be composed of at least one of, for example, a ROM (Read Only Memory), an EPROM (Erasable Programmable ROM), an EEPROM (Electrically Erasable Programmable ROM), a RAM (Random Access Memory), etc.

[0044] The storage 1003 is a computer-readable recording medium. The storage 1003 may be, for example, at least one of a hard disk drive, a flexible disk, a magneto-optical disk, an optical disk such as a CD-ROM (Compact Disc ROM), etc. The storage medium may be, for example, a database including the memory 1002 and / or the storage 1003, a server, or other suitable medium.

[0045] The communication device 1004 is a device for communicating between computers via a wired and / or wireless network. For example, some of the various processes of the logistics and process control device 1 may be realized by the communication device 1004.

[0046] The input device 1005 is an input device (for example, a keyboard) that receives input from the outside. The output device 1006 is an output device (for example, a display) that outputs to the outside.

[0047] The above devices are connected by a bus 1007 for communicating information. The bus 1007 may be configured as a single bus or may be configured as different buses between the devices.

[0048] (Logistics / process control method) Next, with reference to FIG. 7, a method of accumulating the results of reading tags will be described as part of the logistics and process management method using the logistics and process management device 1.

[0049] 7, the logistics / process management device 1 first executes step S01. In step S01, the tag information acquisition unit 11 of the information registration unit 10 acquires tag information (such as what kind of tag is used) provided from an external device and stores it in the memory unit 30. Next, the logistics / process management device 1 executes steps S02 and S03. In step S02, the tag reading information acquisition unit 12 of the information registration unit 10 acquires tag reading information sent from the terminal device 5 or the like.

[0050] In step S03, the information stored in the storage unit 30 is updated based on the information acquired by the tag reading information acquisition unit 12 of the information registration unit 10. Note that, if necessary, the logistics / process management device 1 may also execute step S04. In step S04, tags are associated with each other. Depending on the method of managing information in the storage unit 30, tags of the preceding process and the following process may be associated with each other to associate information stored in the storage unit 30.

[0051] Next, a method for accumulating tag read results in the logistics and process management method using the logistics and process management device 1 will be described with reference to Fig. 7. Step S01 in the method shown in Fig. 7 is performed when starting management of a specific material. Step S01 can also be performed when the material management method changes. Steps S02 to S04 are repeatedly performed from the time when a design document for the material to be managed is created until the material is installed in the target building.

[0052] Next, a method for outputting information stored in the storage unit 30 in the logistics and process management method using the logistics and process management device 1 will be described with reference to FIG.

[0053] 8, the logistics and process control device 1 first executes step S11. In step S11, the output instruction acquisition unit 21 of the analysis and output unit 20 acquires an output instruction provided from an external device. Next, the logistics and process control device 1 executes steps S02 and S03. In step S12, the output unit 22 of the analysis and output unit 20 extracts necessary information from the information stored in the memory unit 30 based on the instruction content included in the output instruction.

[0054] In step S13, the output unit 22 of the analysis and output unit 20 performs calculations as needed based on the information extracted and acquired from the memory unit 30. This calculation is performed when a calculation is required in the output instruction (for example, when calculation of total time is required). An example of analysis is the evaluation of work time related to the production of materials. In this case, it is conceivable to calculate the difference between adjacent elapsed times in order to identify the work time. In this way, further numerical calculations, etc. may be performed on the information extracted from the memory unit 30 depending on the subject of analysis.

[0055] By performing various calculations in step S13, various information can be obtained. Furthermore, this information can be used to manage material movement and adjust processes. For example, analyzing the work time at each stage of a work process can enable the establishment of standard work times for each process, which has been a challenge in the custom-made manufacturing industry. Work time analysis can also be performed for these purposes. Furthermore, analyzing work time allows for the timing and amount of material supply to a specific work site, etc., and time management at each work process stage (e.g., time management taking into account the relationship with the previous process and the design drawing issuance process), enabling consideration of just-in-time management for materials or design drawings. Furthermore, in the construction of buildings and the manufacturing of materials, reducing CO2 emissions, a greenhouse gas, can be an issue. Since the movement of materials can be extracted from the above calculations, the information on the movement of materials can be used to calculate the amount of CO2 consumed at each work process stage. It is also possible to build an inventory database of various information such as materials, time, and CO2 emissions.

[0056] In step S14, the output unit 22 of the analysis and output unit 20 outputs the results. The output contents and output destination are based on the output instruction acquired by the output instruction acquisition unit 21. Note that each of steps S11 to S14 is triggered by, for example, transmission of an output instruction from an external device to the logistics and process control apparatus 1 (i.e., reception of an output instruction by the logistics and process control apparatus 1).

[0057] (Effects of the embodiment) According to the logistics and process control device 1, logistics and process control method, and logistics and process control program described in the above embodiments, different types of tags are used at different stages among multiple work process stages in which work related to materials used in the construction of a building is performed. Therefore, materials are appropriately managed regardless of the work process stage. Meanwhile, the storage unit 30 of the logistics and process control device 1 stores identification information for multiple types of tags attached to specific materials in association with the specific materials. Therefore, the management status of a specific material at different work process stages can be appropriately grasped based on information read from multiple types of tags, thereby more appropriately managing materials used in a building.

[0058] Conventionally, materials have been managed at specific locations and quantities have been managed using tags when managing the transport of materials. However, at construction sites of large buildings, if an event occurs in which the procurement of some of the materials used for construction does not proceed as planned, not only can the construction of the building itself be disrupted as planned, but it may also affect the inventory management of other materials. Therefore, for example, in addition to material inventory management at construction sites, management of the material preparation status (manufacturing status) may also be required. In response to this, the above-mentioned logistics and process management device 1 is configured to manage materials using different types of tags at multiple work process stages, thereby enabling management of materials not only at specific locations but also at the stage of manufacturing the materials, for example. Furthermore, by configuring the device to associate information related to tags attached to specific materials with the specific materials and manage them, appropriate management can be performed for each material. Since the status of materials at different work process stages in multiple work process stages can be individually grasped, comprehensive management of materials related to the construction of a building is possible in addition to management of specific materials.

[0059] Furthermore, as in the above embodiment, when the tag reading information includes information specifying the date, time, and location of tag reading, the progress of the work process can be grasped in more detail by using the date, time, and location of tag reading. Note that the same effect as above can be achieved even if at least part of the date, time, and location of tag reading is managed, for example, only general information about the date and location of tag reading. However, in an environment where it is also necessary to understand the management of materials by time period, more detailed management can be achieved by specifying the details of the time and location of tag reading.

[0060] The tag read information may also include information in which identification information for multiple types of tags attached to materials is associated with information specifying a single date and time. In this case, the associated identification information can be used to associate tags related to a specific material, making it possible to associate tags easily and reliably. This allows for appropriate management of materials.

[0061] The multiple work process stages may include a stage for manufacturing materials and a stage for managing materials after manufacturing. When materials are used in a building, it is necessary to properly understand the management status of the materials in both the stage related to the manufacturing of the materials and the stage for managing the materials after manufacturing. In such an environment, the above configuration makes it possible to more appropriately manage materials used in the building.

[0062] The building may also be made to order. When the building is made to order, the number and variety of materials will be large, and the reuse of these materials for other buildings will be restricted due to the individual orders. Therefore, in order to shorten the construction period in order to gain greater profits, more detailed management may be required. Therefore, by using the above-mentioned logistics and process management device for management, materials can be more appropriately managed, and the manufacturing of the building itself can also be more appropriately managed. Note that the building is not limited to made to order buildings, but the above method is effective for large buildings where many different types of materials are used in large quantities.

[0063] (Variation) Although the embodiments have been described above, the present invention is not necessarily limited to the exemplified embodiments, and can be modified as appropriate within the scope of the gist thereof.

[0064] For example, the device configuration of the logistics / process management device 1 is an example and can be changed as appropriate. Also, while Fig. 2 shows an example in which the components of the logistics / process management device 1 are integrally configured, this configuration is not particularly limited. For example, the storage unit 30 may be provided in a cloud or the like.

[0065] In the above embodiment, a configuration for collectively managing tags attached to materials has been described. However, for example, tags for tools, parts, etc. that are used at the same time as a specific material may also be associated and managed. For example, in FIG. 3, a tag is also attached to a container (basket) that stores piping. With such a configuration, the tag-related information D1 stored in the memory unit 30 may be information that makes it possible to identify the storage location of the piping.

[0066] The tag combinations in the above embodiment are merely examples and may be changed as appropriate depending on the materials used. Therefore, the tag information acquired by the tag information acquisition unit 11 of the information registration unit 10 may also be changed depending on the materials. [Explanation of symbols]
