JP 2000-305616 A

  When planning a work plan for manufacturing large-scale products and construction work, it is necessary to carefully set up where the work procedures included in each work process are performed in the factory or construction site. Specifically, where the raw materials and components are carried in, where the processing and assembly are performed, where the work machines used for processing, assembly, and transportation are located, where the work machines are placed If other things already exist, it will not be completed as a feasible plan without deciding where to move it. In addition, attention must be paid to the location of multiple work processes that run in parallel.

  In order to set up such a place, it is common to use CAD (Computer Aided Design) to generate a layout drawing in which materials, members, work machines and the like are arranged. For example, in an operation having the process A including the procedure α1-α2-α3 and the process B including the procedure β1-β2-β3, it is assumed that the procedure β1 of the process B is started when the procedure α1 of the process A is completed. Actual layout drawings of the time when the process proceeds, the time when the procedure α2 and the process β1 proceed in parallel, the time when the procedure α3 and the process β2 proceed in parallel, and the time when the procedure β3 proceed are actually created, It is visually confirmed whether or not there is any interaction, and the plan is explained to related persons (persons in charge of each work process, etc.), and opinions regarding workability are heard.

  With the conventional method of manually creating the layout drawings for each period, a lot of time is consumed in drafting the work plan itself. The reason for this is that there is a space between processes, so the start of process B is delayed, or conversely, the start of process B is moved forward in order to reduce the overall construction schedule. It is necessary to create a plan and hold a plan briefing each time. However, the consistency of the relationship between the work plan and the layout must be managed by the designer based on the knowledge and experience of the designer, and a great deal of man-hours are required. This is because it requires a check man-hour. In addition, there is a great problem that a work plan cannot be made unless the designer has the expertise and experience.

  The present invention, which has been made in consideration of the above, intends to realize a system that facilitates planning or changing a work plan by linking time management and place management of work processes.

  The present invention supports the planning of a work plan that allows a plurality of work processes to proceed in parallel in the same work space, and is arranged in the work space when each work process is performed. An object information storage unit that stores object information that is information defining the outline of a virtual object that imitates an occupied resource, a time required for one or a plurality of work procedures included in each work process, and any resource in the work procedure A work procedure information receiving unit for receiving work procedure information which is information for designating a movement path, a moving means, and an operation at the time of movement. The work procedure information storage unit that stores the work procedure information received in step S4, and from which time point (usually, time and / or date) each work process starts. A work plan information receiving unit that receives work plan information that is information to be determined, a work plan information storage unit that stores work plan information received by the work plan information information receiving unit, and work plan information from the work plan information storage unit Read out the work procedure information from the work procedure information storage unit, and what work procedure each work process has reached at a certain time based on the start time of each work process and the time required for the work procedure included in each work process. And a work situation determination unit that knows the resource required in the work procedure and the location of the resource, and the object information is read from the object information storage unit, and the necessary information obtained by the work situation judgment unit is obtained. A virtual image corresponding to the resource is placed in the virtual space simulating the work space and the resulting image is placed in the location corresponding to the location of the resource. To constitute a work schedule planning support system comprising an object display control unit for displaying on the display. Here, the “work space” corresponds to, for example, a factory site, a construction site, the inside of a relatively large store or warehouse, and the like. “Resources” is a concept that encompasses raw materials and parts, intermediate products or final products, machines or equipment used for work, personnel required for work, space required for work, pathways representing the movement path of resources, etc. It is. An “object” may represent the size or shape of a tangible object, the size or shape of a space occupied during work, a three-dimensional spatial range in which work instructions can be transmitted, a worker's visual field range, etc. It may also express “Accept information” means acceptance of manual input via an operation input device, reading from a storage device, or reception via a telecommunication line. Further, “time” and “time point” are not limited to the hour / minute unit, and may be a day unit, a week unit, a month unit, or a second unit.

  In this work plan planning support system, time management and place management of work processes are linked through link of object information, work procedure information, and work plan information. The user arbitrarily designates the start time of each work process as work plan information, and confirms the linked work procedure information and object information, so that the work space can be confirmed (as a result of designation of the start time of each work process). What resources are placed at which locations, which space is used to move resources, and where there is a place between one work process and another work process or between work paths You can visually check if it does not occur. This not only relieves the user of the trouble of manually creating a large number of layout drawings when drafting or changing a work plan, but also delays or advances any process through the input, change, and update of work plan information. The work plan that is not established as a work space is eliminated, and a wasteful waiting time during which no work process is progressing while maintaining the spatial feasibility of the work plan is eliminated. It becomes possible to make a reduced work plan. In addition, it is reasonable to explain the spatial logical feasibility of the work plan to relevant parties, explain the validity of the plan, and further compile and improve the plan by gathering the opinions of the parties on the spot. Therefore, it is possible to improve the efficiency of planning, and it is not necessary to convene related parties over and over, and it is possible to facilitate communication within the project.

  In order to meet practical requirements, the work plan information is read from the work plan information storage unit, the work procedure information is read from the work procedure information storage unit, the start time of each work process and the work procedure included in each work process It is desirable that the system further includes a schedule display control unit that displays a list of the start time and end time of each work process on the display based on the required time. Typically, a list of each work process is displayed on the display as a task / gant chart.

  The work status judging unit determines the location of the resource, the movement route, and the use space required for the work procedure of another work process in which the resource placement location required for the work procedure of one work process is performed at the same time. The object display control unit or the schedule display control unit determines that the work status determination unit interferes with the resource location, movement route, and usage space. If a warning to that effect is displayed on the display, the burden on the person in charge of work planning can be further reduced.

  ADVANTAGE OF THE INVENTION According to this invention, cooperation with time management and place management of a work process can be aimed at, and a work plan can be drawn up or changed easily.

Embodiments of the present invention will be described with reference to the drawings. First, a specific example of work that can be planned using the work planning support system of this embodiment will be described. What is handled here is the assembly process of the product 2, and an outline thereof is shown in FIGS. For the assembly process of product 2,
(1) First process of bending and welding the material steel plate 21 to create a cylinder 22 (2) Second process of welding a plurality of cylinders 22 in the axial direction (3) Openings on both sides of the cylinder 22 The third process of welding the lid 23 to (4) a process such as a paint finish is included. In addition, in order to actually manufacture in the factory as a work space,
(A) Loading of the steel plate 21 into the steel plate loading location 31 (B) Loading of the lid 23 into the second and third machining locations 34 (C) Material steel plate 21 from the steel plate loading location 31 to the first machining location 32 (D) Transport of the cylindrical body 22 from the first processing place 32 to the cylindrical body storage place 33 (E) Transport of the cylindrical body 22 from the cylindrical body storage place 33 to the second and third processing places 34 (F) Transport of assembled finished product from second / third processing place 34 to painting place 35 (G) Transportation of product 2 from painting place 35 to inventory place 36 is also required. Overall, the order is (A)-(B)-(C)-(1)-(D)-(E)-(2)-(3)-(F)-(4)-(G). Then, the production of the plurality of products 2 based on the manufacturing process is advanced by one or more lines in the factory with a time difference. Although the work in the above example is a process in which similar processes are performed in parallel, it is naturally possible to use the work plan planning support system of the present embodiment for planning a work plan having a plurality of processes having different contents. It is.

  The work planning support system of this embodiment will be described in detail. The system of this embodiment is mainly composed of a computer 1, a so-called personal computer, a workstation, a server, and the like. For example, as shown in FIG. 3, the computer 1 includes hardware resources such as a processor 1a, a main memory 1b, an auxiliary storage device 1c, a display control device 1d, an operation input device 1f, and a communication interface 1g. (Controller, I / O controller, etc.) The auxiliary storage device 1c is an optical disk drive, a hard disk drive, a flash memory, or the like. The display control device 1d includes, as elements, a graphics processor that generates image data to be displayed based on a drawing command received from the processor 1a and sends the image data to the display 1e, a video memory that temporarily stores image data and the like. To do. The operation input device 1f is a pointing device such as a keyboard, a mouse, a track pad, and a touch panel (which may be superimposed on the display 1e) that can be operated with fingers. The communication interface 1g is a device for performing data communication via a telecommunication line, and is typified by a NIC (Network Interface Card) or a wireless transceiver, but in addition to this, an interface such as a USB (Universal Serial Bus) is adopted. You can also

  A program to be executed by the processor 1a is stored in the auxiliary storage device 1c. When the program is executed, the program is read from the auxiliary storage device 1c to the main memory 1b and decoded by the processor 1a. In this embodiment, a known OS (Operating System) program and various device driver programs attached thereto are installed in advance to mediate use of hardware resources by other programs. In addition, the programs necessary for configuring the work plan planning support system according to the present invention are installed, and the hardware resources are operated according to these programs, and the object information storage unit 101 shown in FIG. Functions as the work procedure information receiving unit 102, work procedure information storage unit 103, work plan information receiving unit 104, work plan information storage unit 105, work status determination unit 106, object display control unit 107, and schedule display control unit 108 To do.

  The object information storage unit 101 stores object information. Object information is information used to display objects that simulate various resources necessary for work in a three-dimensional virtual space that simulates the work space, and is usually described according to a known data format. 3D model data. As shown in FIG. 5, the object information storage unit 101 uses the storage area of the main memory 1b or the auxiliary storage device 1c to associate the object information with a type identifier that identifies the type of resource represented by the object information. Remember. When applied to the above example, the material steel plate 21, the cylinder 22, a member such as a lid, a forklift 41 necessary for transporting the member, a work machine such as a crane 42 necessary for transporting the assembled product, a steel plate loading place 31, a second Spaces such as one processing place 32, second / third processing place 34, painting place 35, inventory place 36 are necessary resources, and object information for each resource (material steel plate 21, forklift 41, first processing place) (Such as 32) and associated with a type identifier representing a resource type.

The work procedure information receiving unit 102 receives input of work procedure information. The work procedure information is information that designates the time required for the work procedure included in the work process and which location in the work space to arrange which resource. More specifically, commands that place objects in the virtual space or operate objects that are already set in the virtual space are arranged in the order of execution, and each work procedure is expressed by one or more commands. Yes. One command includes an individual identifier for identifying a target object individual, a type identifier for identifying a resource type of the target object, a command type, and accompanying parameters. Supplementing the difference between the individual identifier and the type identifier, for example, when a plurality of forklifts 41 are arranged in the factory, the individual identifiers are different (No. 01 car, No. 02 car,...) Is the same (forklift). The following types of commands exist.
<Attach> A command to move the target object in the virtual space and attach it to the target. As an accompanying parameter, target (coordinate values (x, y, z) specifying a place in the virtual space, or individual identifier specifying an existing individual object in the virtual space), from which direction to attach to the target ( x, -x, y, -y, z or -z), movement trajectory (an object representing a transit point, an object representing a movement path such as a rail, and a straight line, a parabola, a function curve, etc. when attaching) Set the time required for execution). The attach command is used for newly setting an object and for operating an existing object. In order to install an object corresponding to a space provided in a factory, for example, a dummy process (for space object installation, not an actual process) is provided at the beginning of work, and the work procedure information related to the process is provided. What is necessary is just to describe the attach command of the required time 0 which attaches a space object to a required coordinate value. A work procedure for carrying or moving a member into a required space can be expressed by a command for attaching a target member object to the required space object. Further, when an object is attached to another object, the other follows the one movement unless the following detach command is used. In other words, both objects are integrated. If this is utilized, the conveyance of the member using a work machine, the connection of members, etc. can be expressed. Also, by defining how much offset value to attach the moving means such as tools and forklifts used in the work procedure, it is possible to simultaneously express the influence of the tools and moving means attached to the member object. it can.
<Detach> A command to move the target object alone in the virtual space and attach it to the target. The accompanying parameters are based on the attach command. If you attach an object to another object and then attach either object to another target, both objects move together toward the target, but if you detach one object to another target Only the target object moves towards the target. If this is utilized, the unloading of the member from a work machine, the cutting | disconnection of members, etc. can be expressed.
<Wait> A command to wait for the target object at the same place in the virtual space. The time required for execution is set as an accompanying parameter. This can be used to express work procedures that do not involve movement of members, work machines, etc., shape processing, painting, and the like. For example, for a material steel plate object 21 attached to or detached from the first machining location object 32, a weight command with the type identifier cylinder 22 is described (without changing the individual identifier). Processing of the material steel plate 21 into the cylindrical body 22 is expressed.
<Walk attach> A command for moving a target object in a virtual space along a route and attaching it to a target. As an accompanying parameter, the target, from which direction to attach to the target, the trajectory of movement (straight line, parabola, function curve, etc.), and one or more control points (coordinate values (x , Y, z), or an individual identifier for designating an existing object individual in the virtual space. In the walk attach command, since the time required for execution is calculated on the computer 1 side, the required time is not an accompanying parameter. The other points are the same as the attach command.
<Walk Detach> A command for moving the target object alone in the virtual space along the route and attaching it to the target. The accompanying parameters are based on the walk attach command. In the walk detach command, since the time required for execution is calculated on the computer 1 side, the required time is not an accompanying parameter. The other points are the same as the detach command.
The work procedure information receiving unit 102 receives manual input of work procedure information using the operation input device 1f. The work procedure information receiving unit 102 can also read the work procedure information stored in advance in the auxiliary storage device 1c, or can receive work procedure information transmitted from the outside via the communication interface 1g. it can.
In addition to the above-described commands (for moving an object, assembling, etc.), there may be a processing command for processing an object. In the processing command, the object is deformed from the original shape to the shape corresponding to the designated parameter by designating parameters such as bending, cutting, and punching the member at the designated position. Alternatively, it is possible to prepare a pre-processed and post-processed object model, and replace the pre-processed object model with the processed object so as to express the processed model. When a part is expanded into multiple parts with processing, it is possible to specify the main part and keep it alive, and also add a new individual identifier to the sub part and use it in the subsequent process. Alternatively, the subparts can be left in the process and exist as waste parts, and can be used for examination of waste part management given an identifier for collection management of the waste parts.

  The work procedure information storage unit 103 stores the work procedure information received by the work procedure information receiving unit 102. As shown in FIG. 6, the work procedure information storage unit 103 uses the storage area of the main memory 1b or the auxiliary storage device 1c to identify the work procedure represented by the work procedure information in the work procedure information. Store it in association with. When applied to the above example, each of the plurality of lines for assembling the gas tank 2 is one work process, and work procedure information is stored in association with an individual process identifier for each assembly line.

  The work plan information receiving unit 104 receives input of work plan information. The work plan information is information that designates from which point the work process starts. The work procedure information receiving unit 102 receives manual input of work procedure information using the operation input device 1f. The work procedure information receiving unit 102 can also read the work procedure information stored in advance in the auxiliary storage device 1c, or can receive work procedure information transmitted from the outside via the communication interface 1g. it can.

  The work plan information storage unit 105 stores the work plan information received by the work plan information receiving unit 104. As shown in FIG. 7, the work plan information storage unit 105 uses the storage area of the main memory 1b or the auxiliary storage device 1c to convert work plan information into a work process whose start point is specified by the work plan information. It is stored in association with the process identifier to be identified. When applied to the above example, work plan information is stored in association with individual process identifiers for each assembly line.

  FIG. 13 shows a conceptual diagram of a data structure constructed by a link of work plan information, work procedure information, and object information. The data structure has a three-layer structure including a schedule layer related to the schedule of the work process, a work layer related to a specific work command included in the work process, and a space layer related to an object installed or operated in accordance with the execution of the work command. The schedule layer and the working layer are symbolically linked through process identifiers as symbols. The working layer and the space layer are symbolically linked through individual identifiers that are symbols. The schedule layer, work layer, and space layer can be edited and processed independently of each other, and even if correction is made for myopic purposes without being aware of the data relationship of each layer, the global relationship is grasped by symbolic links And overall linkage is maintained. As a secondary effect, it is possible to supplement the influence of partial modification of data on the definition of other data (such as work space and equipment used).

  The work status determination unit 106 reads out the work plan information from the work plan information storage unit 105 and the work procedure information from the work plan information, and determines which work procedure each work process has reached at the time based on the information. At the same time, the resource required in the work procedure, the location of the resource, the movement route, the movement occupation space corresponding to the movement operation, the movement equipment, and the occupation space of the work area are acquired. The work plan information describes the start time of the work process, and the work procedure information describes a command simulating a work procedure that is sequentially executed from the start time of the work process and the time required for the command. Therefore, by comparing the time difference from the start time of the work process to the determination reference time with the accumulated value of the required time of the command, it is possible to know the command being executed at the determination reference time. In addition, the work status determination unit 106 determines that the location and movement route of resources necessary for the work procedure of one work process, the movement occupation space corresponding to the movement operation, the movement equipment and the occupation space of the work area are the same period. Judgment is also made as to whether or not there is interference with the location and movement route of resources required for the work procedures of other work processes carried out in, movement occupation space corresponding to movement operation, movement equipment and occupation area occupation space To do. For example, if the time difference from the start of the first assembly line to the start of the second assembly line is sufficiently small, the second line member is brought in even though the first line member remains at the processing location. There is a risk of inconveniences such as being lost. The work status determination unit 106 determines whether or not such a location interaction has occurred.

  The determination processing procedure by the program will be described with reference to the flowchart of FIG. For convenience of explanation, a counter variable indicating one point on the time axis is c, a variable indicating how many steps the work process m has reached is n [m], and an arrangement location of the object individual o in the virtual space Let p [o] be the variable shown. These c, n, and p are temporarily stored in the register of the processor 1a or the main memory 1b. The initial value n = 0 and the initial value p is empty.

  First, at the time point c, it is investigated what number of commands each work process has reached, and where each object is located in the virtual space. For one work process m, the work procedure information associated with the process identifier of the process m is referred to, and the time required for the n [m] -th commands included in the process m is accumulated (step S1). When the n [m] -th command includes a walk attach command or a walk detach command, the path of the object defined as an accompanying parameter is divided by a predetermined moving speed value. Calculate the time required for the command. Before and after this, the work plan information associated with the process identifier of the process m is referred to, and the elapsed time from the start time of the process m to the time c is calculated (step S2). Then, the accumulated total time required for the n [m] -th command is compared with the elapsed time from the start time point to the c time point (step S3). If the accumulated time required for the n [m] th command is equal to or greater than the elapsed time from the start time to the c time point, the n [m] th command is still being executed at the c time point, and step S7 is executed. Transition to. Conversely, if the total time required for the n [m] -th command is less than the elapsed time from the start time to the c time, the n [m] -th command is completed at the c time, and n [M] The execution of the first command is started. Therefore, for the object o set or operated by the n [m] -th command, the target of the command and the direction of attachment to the target are temporarily set as p [o] indicating the arrangement location of the object o at time c. Store (step S4). In addition, n [m] is incremented (+1 increased) (step S5). Subsequently, if the incremented n [m] exceeds the total number of commands included in the process m (step S6), the process m has already ended at time c, and the process proceeds to step S7. Otherwise, it returns to step S1. The above steps S1 to S6 are executed for all work steps m (steps S7 and S8). In step S4, the state after the execution of the n [m] -th command is evaluated, but the state during the execution of the command may be evaluated. In that case, a method of obtaining a state by temporally interpolating a movement operation or a work operation based on a command can be adopted.

  Next, it is determined whether or not resources (particularly, space, movement space occupation space, work machine, work machine operation space, etc.) are being exchanged between a plurality of work processes at time point c (step S9). In step S9, for example, when p [o] ≈p [o ′] is established for different object individuals o and o ′, it is determined that these objects o and o ′ have the same arrangement location. At this time, the spatial relationship between the objects o and o ′ may be evaluated and determined by logical product, or collision (collision) determination based on the work operation may be executed. In the collision determination, the object information associated with the type identifier of each object o, o ′ is read from the object information storage unit 101, the work operation is executed with reference to this, and the outer shape of the objects o, o ′ is the virtual space. To determine if they are interfering with each other. Further, regarding different work steps m and m ′, the arrangement is also performed when the target and attach direction of the n [m] -th command match the target and attach direction of the n [m ′]-th command. Judge that they are meeting each other. In addition, when the object individual targeted by the n [m] -th command matches the object individual targeted by the n [m ′]-th command, it is determined that the object is held. If it is determined in step S9 that a resource conflict has occurred, information indicating that a resource conflict has occurred at time c is stored in the main memory 1b or the auxiliary storage device 1c (step S10). This information includes individual identifiers of object individuals o and o ′, p [o] and p [o ′], process identifiers of work processes m and m ′, n [m] and n [m ′], and the like. Can do.

  Thus, the above steps S1 to S10 are repeatedly executed while incrementing the time counter c (steps S11 and S12).

  The object display control unit 107 reads out the object information from the object information storage unit 101, and arranges the virtual object corresponding to the necessary resource acquired by the work situation determination unit 106 in the virtual space imitating the work space. An image as a result of being arranged at a location corresponding to is displayed on the display 1e. Through the above-described determination processing, information on the arrangement location p [o] of the object individual o at the time point c is already known. Based on this information, the object display control unit 107 generates an image in which each object individual o is arranged in the virtual space, and sends it to the display 1e. When rendering the object o, the object information associated with the type identifier of the object o is read from the object information storage unit 101 and processed by the graphics processor. A screen display example is shown in FIG. When a plurality of processes are progressing in parallel at the time point c, objects related to the procedure of each process executed at the time point c are displayed at the same time. Further, if the process of generating and sending the image at the time point c based on p [o] obtained through the determination process is repeatedly executed while incrementing the time counter c, the commands of the respective work steps are executed in parallel in the virtual space. Thus, it is possible to display an animation that is executed sequentially. Of course, it is also possible to display a still image at a specific time point, for example, the current time point designated by the user via the operation input device 1 f or acquired from the time measuring circuit of the computer 1.

  In addition, if it is determined in the determination process in the work status determination unit 106 that resource sharing among a plurality of work processes has occurred, a warning to that effect is displayed on the display. be able to. An example of the screen display is shown in FIG. The warning text includes the time when the resource conflict occurs, the process identifiers of the multiple work processes that are engaged in the resource, the order of the commands being executed at that time, and the object objects that are interfering in the virtual space. Any individual identifier or the like can be included. These pieces of information are stored in the above step S10.

  The schedule display control unit 108 reads the work plan information from the work plan information storage unit 105 and the work procedure information from the work procedure information storage unit 103, and displays a list of the start time and end time of each work process on the display. The schedule display control unit 108 adds up the time required for all commands described in the work procedure information for each work process, and sets the time when the total time has elapsed from the start of the work process as the work process end time. calculate. When the command includes a walk attach command or a walk detach command, the travel time of the command is calculated by dividing the distance of the movement path of the object defined as the accompanying parameter by a predetermined movement speed value. Then, for example, a task Gantt chart in which the process identifier, the start time point, and the end time point are written for each work process is generated and sent to the display 1e. An example of screen display is shown in FIG. On the Gantt chart, it is preferable to draw a line indicating the current time point obtained from the timing circuit of the computer 1.

  Further, in the determination process in the work status determination unit 106, when it is determined that there is a resource conflict between a plurality of work processes, a warning to that effect is displayed on the display. Can do. A screen display example is shown in FIG.

  According to the present embodiment, a work plan for supporting a plurality of work processes in parallel in the same work space is supported, and is arranged in the work space when each work process is performed. An object information storage unit 101 that stores object information that is information defining the external shape of a virtual object that imitates a resource that occupies a partial area, a time required for one or a plurality of work procedures included in each work process, and the work procedure thereof The work procedure information receiving unit 102 that receives work procedure information that is information for designating which resource is to be placed in the work space, and the work procedure information received by the work procedure information receiving unit 102 are stored. A work procedure information storage unit 103 and a work plan information that is information for designating from which point each work process starts. The plan information receiving unit 104, the work plan information storage unit 105 for storing the work plan information received by the work plan information information receiving unit, the work plan information from the work plan information storage unit 105, and the work procedure information storage unit The work procedure information is read from 103, and it is determined which work procedure has reached each work process at a certain time based on the start time of each work process and the time required for the work procedure included in each work process. The work status determination unit 106 that knows the resources required in the procedure and the location of the resource, and the object information is read from the object information storage unit 101 and corresponds to the necessary resources acquired by the work status determination unit 106. An image obtained as a result of arranging the virtual object in a location corresponding to the location of the resource in the virtual space simulating the work space is displayed. To constitute a work schedule planning support system comprising an object display control section 107 to be displayed on the play. In this system, time management and location management of work processes are linked through link of object information, work procedure information, and work plan information. In this way, the user can arbitrarily designate the start time of each work process, and what resource is arranged in which place in the work space as a result of the designation, and one work process and other work processes. It is possible to visually check whether or not there is a place conflict. This not only relieves the user of the trouble of manually creating a large number of layout drawings when drafting or changing a work plan, but also delays or advances any process through the input, change, and update of work plan information. The work plan that is not established as a work space is eliminated, and a wasteful waiting time during which no work process is progressing while maintaining the spatial feasibility of the work plan is eliminated. It becomes possible to make a reduced work plan. In addition, it is reasonable to explain the spatial logical feasibility of the work plan to relevant parties, explain the validity of the plan, and further compile and improve the plan by gathering the opinions of the parties on the spot. Therefore, it is possible to improve the efficiency of planning, and it is not necessary to convene related parties over and over, and it is possible to facilitate communication within the project.

  The work plan information is read from the work plan information storage unit 105 and the work procedure information is read from the work procedure information storage unit 103, and each work is determined based on the start time of each work process and the time required for the work procedure included in each work process. Since the system further includes a schedule display control unit 108 that displays a list of process start and end times on the display, it is possible to meet practical demands for simply checking the start to end schedule of each process. .

  Whether the work situation determination unit 106 interferes with the location of resources required in the work procedure of another work process performed at the same time as the location of resources required in the work procedure of one work process If the object display control unit 107 or the schedule display control unit 108 determines that the work location determination unit 106 interferes with the location of the resource, a warning to that effect is displayed on the display. Since it is displayed, the burden on the person in charge of work planning can be further reduced.

  The present invention is not limited to the embodiment described in detail above. For example, in the above embodiment, the virtual space and the object are three-dimensionally modeled. However, a two-dimensional (planar) model that does not take the height direction into consideration may be used.

  The schedule display control unit 108 may draw or display a list of the start time and end time of each process in a format other than the task / gant chart.

  Moreover, the function of each part shown in FIG. 4 is disperse | distributed to the some computer 1, and the aspect which establishes the work planning support system which concerns on this invention by those cooperation is not prevented.

  In addition, the specific configuration of each unit, the processing procedure, and the like can be variously modified without departing from the spirit of the present invention.
