  When the update button 506 is clicked by the user via the input unit 209, the progress information input to the work progress 502 is acquired, the progress of the work information table is updated, and the arrangement information display screen 300 is returned.

  When the user clicks a cancel button 508 via the input unit 209, the user returns to the arrangement information display screen 300 without updating.

  FIG. 11 shows the configuration of the workload display screen. The workload display screen 600 is a screen that displays the workload of the entire plan after creation of the work plan in time series, and includes a process selection tab 602 and a display. A time selection combo box 604 and a work load display unit 606 are provided.

  When the user clicks on the process selection tab 602 via the input unit 209, the corresponding process at the clicked position is acquired and the workload display unit 606 is updated.

  When the selection item of the display time selection combo box 604 is switched by the user via the input unit 209, the display time of the selection item is acquired and the workload display unit 606 is updated.

  When updating the workload display unit 606, information on the arrangement of the members for a predetermined time interval in the time selected in the display time selection combo box 604 is acquired from the corresponding time of the start-up input, and the information on the arrangement of each time For each work in progress in the information, the process load of the process selected in the process selection tab 602 is acquired from the work process table (FIG. 13), and the work load of the corresponding process is accumulated and calculated. The calculation result is graphed and displayed on the work load display unit 606.

  In step S100, the client terminal 102 acquires the plan start time 304 and the end time 310 displayed on the arrangement information display screen 300 shown in FIG. 8, and sets the time acquired by the plan start time 304 as the plan start time. .

  In step S102, the client terminal 102 constructs an arrangement information object at the planned time acquired in step S100. Detailed processing relating to the construction of the placement information object will be described with reference to the flowchart shown in FIG.

  In addition, in the arrangement information display screen 300, when the information regarding the arrangement of the member displayed on the arrangement information display unit 312 is changed, the changed content is the information regarding the arrangement of the member at the planned time.

  In this step, the constructed arrangement information object is added to the planning arrangement information set.

  In step S104, the client terminal 102 adds 1 to the planned time set in step S102. In the embodiment of the present invention, 1 is added. However, it is not particularly limited to this value, and an appropriate value can be set when referring to the arrangement information.

  For example, when the plan start time 304 and the end time 310 are set in days, when the simulation is performed at intervals of one day, it is possible to take a mode in which 1 is set. When simulation is performed, 2 can be set.

  Moreover, when the plan start time 304 and the end time 310 are set by the date and time, when the simulation is performed at an interval of 1 hour, it is possible to take an aspect of setting 1 but at the interval of 2 hours When simulation is performed, 2 can be set.

  Next, the processing from step S106 to step S118 is executed for each placement information object included in the planning placement information set added in step S102.

  In step S106, the client terminal 102 sets the planned time set in step S100 in the arrangement information object included in the planning arrangement information set.

  In step S108, the client terminal 102 updates the progress of the corresponding work, and detailed processing regarding the update of the work progress will be described later with reference to the flowchart shown in FIG.

  In step S110, the data server 104 acquires the product type and the member ID from the scheduled work start information table (FIG. 13) having the scheduled start time, using the planned time used in step S106 as the scheduled start time. All information is acquired from the member work condition table having the type and member ID.

  In this step, after acquiring new work information, the progress included in the new work information is added to the current arrangement information as unstarted information.

  In step S112, the client terminal 102 sets planning parameters. The planning parameters indicate a random number seed, a distribution threshold, and the like.

  In step S114, the client terminal 102 copies the arrangement information object acquired in step S106 to form an arrangement information copy object. In step S116, the client terminal 102 changes the arrangement information copy object obtained by copying in step S114. On the other hand, processing related to the work member placement plan, such as movement of each member and update of placement information, is executed. Detailed processing relating to the work member arrangement plan will be described with reference to FIG.

  In step S118, the client terminal 102 adds the arrangement information object for which the member arrangement plan has been completed in step 116 to the planning arrangement information set. However, the arrangement information object added here is not the target of steps S106 to S116 at the current plan time.

  In step S120, the client terminal 102 sorts the planning arrangement information set after completing the processing from step S106 to step S118, that is, the planning arrangement information set set in step S118.

  At this time, the plan evaluation value of the sort standard is also calculated. In this embodiment, this evaluation value is a sum of delays in work progress and a linear sum of the number of irregular movements. The irregular movement will be described in detail with reference to FIG.

  In step S122, the client terminal 102 determines whether or not the number of pieces of placement information stored in the plan placement information set exceeds the upper limit value of the internal parameter specification. If so, the process proceeds to step S124. If not, the process proceeds to step S126.

  In step S124, the client terminal 102 narrows down the number of planning arrangement information sets to the holding number of planning arrangement information sets designated by internal parameters. At this time, the higher evaluation value in step S120 is preferentially left.

  In step S126, the client terminal 102 determines whether or not the planned time set in step S104 is before the end time acquired in step S100. If not, the process proceeds to step S102, and the end time If so, the arrangement information included in the arrangement information set for planning is displayed on the arrangement information display unit 312 of the arrangement information display screen 300, and the process ends.

  In the above-described processing in the present embodiment, the evaluation value of the arrangement plan is defined by the linear sum of the work progress delay and the irregular number of movements, but this may be changed to another evaluation value. For example, it is possible to set an evaluation value in consideration of efficiency in use of the work place (occupation ratio of the work place) and minimization of the idling work (number of idling work).

  Next, detailed processing relating to construction of information relating to arrangement will be described using the flowchart shown in FIG.

  Note that this process is executed when the CPU 201 of the client terminal 102 detects that the user has pressed the display button 306 of the arrangement information display screen 300 shown in FIG. 8, or executes step S102 in the process shown in FIG. It corresponds to the process when doing.

In step S200, the client terminal 102 acquires the time input as the plan start time 304 of the arrangement information display screen 300 and sets it as the set time. In step S202, the data server 104
In the work plan creation system 100, information about the factory that is the target of the work plan simulation is acquired from the factory section table (FIG. 12).

  The factory partition table includes a factory ID that uniquely identifies the factory, and includes information indicating the size and shape of the factory corresponding to the factory ID.

  When the screen displayed on the display unit 210 of each client terminal 102 includes a rectangular display area, for example, the lower left corner of the rectangle is the origin, the X axis is positive from the origin to the right, and the upward direction is positive. The shape of the factory is drawn using the coordinates composed of the X axis and the Y axis.

  Therefore, as information indicating the size and shape of the factory, the size X indicating the width of the factory, the size Y indicating the vertical width of the factory, the origin position X indicating the lower left X coordinate that is the end point of the factory shape, the factory Is provided with an origin position Y indicating the lower left Y coordinate which is the end point thereof.

  Before the process shown in FIG. 3 is executed, the user uses a screen (not shown) displayed on the display unit 210 of the client terminal 102 to display a list of factories to be an execution target of the work plan simulation. By selecting from a plurality of factories, the factories in this step are specified. At this time, a factory ID is attached to each factory displayed in the list, and the factory information in the factory partition table is acquired using the factory ID.

  In step S204, the data server 104 acquires the arrangement information and work information registered in the work information table (see FIG. 13).

The work information table includes a work ID for uniquely identifying a work, a product ID for uniquely identifying a product, a member ID for uniquely identifying a member, a work type indicating a work type, a time at which the work is performed, a work Scheduled start date and time, work period, scheduled completion date and time indicating the end of the work, start time indicating the actual start time of the work, progress of the current work, work place ID uniquely indicating the work place, position of the member with respect to the work place An arrangement position indicating information,
A rotation indicating a rotation angle used when the member shape registered in the work plan creation system 100 is rotated and arranged at the work place is provided.

  The work information table is composed of a work ID, a product ID, a member ID, a work place ID, and a time as main key items, and any work is performed on any product member at any location and time. Is stored as information.

  Among these items, a work ID, a product ID, a product type (a product type is uniquely identified from the product ID. It can be acquired from a correspondence table (not shown) used for identification, the same applies hereinafter), It is defined as work information having a configuration including member ID, work type, scheduled start date and time, work period, scheduled completion date and time, start time, progress, work place ID, arrangement position, and rotation, and further relates to a set of work information at a predetermined time. It is defined as placement information.

  Thereafter, the processes in steps S206 and S208 are executed for each work place registered in advance in the work plan creation system 100.

  In step S206, the data server 104 acquires information regarding the workplace registered in the workplace table (see FIG. 12), and determines whether the workplace is included in the factory. If the workshop is included in the factory, the process proceeds to step S208.

  The workplace table includes a workplace ID that uniquely indicates the workplace, a factory that indicates the factory ID of the factory where the workplace is installed, a workplace name, a type that indicates the type of the workplace, information that indicates the shape of the workplace with respect to the factory, and a maximum in the workplace. It has a weight upper limit that indicates the possible weight.

  When the screen displayed on the display unit 210 of each client terminal 102 includes a rectangular display area, for example, the lower left corner of the rectangle is the origin, the X axis is positive from the origin to the right, and the upward direction is positive. The Y axis is defined, and the shape of the workplace with respect to the factory is drawn using coordinates composed of the X axis and the Y axis.

  Therefore, as information indicating the shape of the workplace with respect to the factory, with respect to the shape of the workplace with respect to the factory, the coordinate X indicating the lower left X coordinate that is the end point, and the coordinate indicating the lower left Y coordinate that is the end point with respect to the shape of the workplace with respect to the factory Y, size X indicating the length in the positive direction of the X axis with respect to the coordinate X (workplace horizontal width), size Y indicating the length of the Y axis in the positive direction with respect to the coordinate Y (workplace vertical width), with respect to the origin The size Z (workplace height limit) indicating the length in the positive direction of the Z-axis from the origin is provided with respect to the Z-axis with the vertical upward direction being positive.

  In this step, in order to determine whether or not it is included in the corresponding factory, it is determined whether or not the factory ID used in step S202 matches the factory provided in the workplace table. The process proceeds to step S208, and if it is determined that they do not match, the process of step S106 is executed on the information regarding the work place registered in the next work place table.

  In step S208, the client terminal 102 creates an object indicating the shape of the workplace using the information about the factory acquired in step S202, the placement information acquired in step S204, and the information about the workplace acquired in step S206. Add to object.

  Thereafter, Steps S210 to S216 are executed for each work included in the work information acquired in Step S204.

  In step S210, the client terminal 102 determines whether or not the work is performed at the target factory. When it is determined that the work is performed at the target factory, the process proceeds to step S212, and is determined not to be performed at the target factory. If so, the process proceeds to step S212.

  This determination is made by using the work place ID included in the work information and the work place ID corresponding to the factory ID determined to be matched in step S206. The process proceeds to S212, and if it is determined that they do not match, the process of step S210 is performed on the next work information.

  In step S212, the client terminal 102 determines whether it is working at the set time set in step S200. If it is determined that it is working, the process proceeds to step S214, and it is determined that it is not working. If so, the process of step S210 is performed on the next work information.

  As a method of determining whether or not the work is in progress, if the set time set in step S200 is after the start time included in the work information and the progress is less than the work period, it is determined that the work is in progress. If the set time is before the start time or the progress is equal to or longer than the work period, it is determined that the work is not in progress.

  In step S214, the client terminal 102 specifies the work site of the target work at the set time acquired in step S200 from the work place ID of the work information, and specifies the placement position of the member of the target work from the work information placement position.

  In step S216, the client terminal 102 creates an object indicating the arrangement and progress of the member with respect to the work place from the arrangement position specified in step S214 and the progress included in the work information, and adds the object to the arrangement information object.

  In step S218, the client terminal 102 adds the arrangement information object created in step S216 to the planning arrangement information set.

  In FIG. 5, a detailed process related to the update of work progress will be described. In the process related to the update of work progress, steps S300 to S304 are executed for each work included in the arrangement information object.

  In step S300, the client terminal 102 determines whether the target work has been completed from the work information included in the arrangement information object acquired in step S106.

  In this determination in this step, when the work progress included in the work information is outside the range of the work period, it is determined that the target work has been completed, the target is set as the next work, and the process returns to step S300. If it is within the period, it is determined that the target work has not been completed, and the process proceeds to step S302.

  In step S <b> 302, the client terminal 102 determines whether or not the target work can be performed in the work place from the work information included in the arrangement information object acquired in step S <b> 106.

  In step S302, the client terminal 102 determines the product type and member ID of the work information included in the arrangement information object acquired in step S106, the product type and member ID of the member work condition table (FIG. 12) corresponding to the work type, And the work location corresponding to the work type is acquired, it is determined whether the acquired work location and the work location ID included in the work information match, and the work location cannot be obtained or the work location in the member work condition table If the work place ID included in the work information matches, it is determined that the work can be performed, and the process proceeds to step S304. Otherwise, the target is the next work, and the process returns to step S300.

  The member work condition table shows the members constituting the structure to be built, what kind of work is performed on the members, the time required for the work, the factory where the work is performed, the work place in the factory, the weight of the member, the work It has a subsequent work type indicating information such as order dependency, and stores and manages information for determining whether or not the work target member is to perform work in an appropriate work place.

  In step S304, the client terminal 102 determines that the target work is workable, and adds 1 to the progress included in the work information of the target work.

  In FIG. 6, the process regarding the arrangement plan of members will be described.

  First, step S400 to step S414 are executed for each work of the arrangement information object which is the current target, that is, the arrangement information copy object obtained by copying in step S114.

  In step S400, the client terminal 102 determines whether the target work has been completed from the work information included in the arrangement information copy object acquired in step S114.

  This determination in this step determines that the target work is completed when the work progress of the work information is out of the work period, sets the target as the next work, and if the work progress is within the work period, It is determined that the target work has not been completed, and the process proceeds to step S402.

  In the embodiment of the present invention, even when the work progress matches the work period, it is determined that the target work is completed.

  In step S402, the client terminal 102 determines whether there is a subsequent work in the target work. As a method for determining subsequent work in this step, work is performed on the product type, member ID, and product type, member ID, and subsequent work type corresponding to the work type corresponding to the work type included in the work information. A determination is made based on whether or not the seed is set. If the subsequent work is set, the process proceeds to step S404. If the subsequent work is not set, the process proceeds to step S406.

  In step S <b> 404, the client terminal 102 starts subsequent work on the corresponding member of the target work. In step S404, the work type included in the work information corresponds to the work type set in the subsequent work type in step S402, the product type of the work information, the member ID, and the work type assigned in this step. Work information to be acquired is used as subsequent work information.

  Other information such as the work period and work place corresponding to the product type, member ID, and work type of the member work condition table is acquired.

  For the subsequent work information, other information acquired from the member work condition table is set, and the time and start time are the planned time in step S106, and the scheduled end date and time are the work time of the work information added to the start time. The value and the work place ID are set to blank, and the progress is set to 0. For the work place ID, the arrangement position, and the rotation, the work information value of the corresponding work (not the subsequent work information) in this step is set. Set. Thereafter, the corresponding work (not the subsequent work) is deleted from the work information set of the arrangement information.

  Then, the target work is set as the next work, and the process returns to step S400.

  In step S406, the client terminal 102 executes the movement of the work completed member. Detailed processing regarding the movement of the members will be described in detail with reference to FIG.

After completing the processes from step S400 to step S406, the processes related to steps S408 to S414 are executed again for each work.

  In step S408, the client terminal 102 determines whether the target work has been completed in the same procedure as in step S400, using the same method as that in step S400. If the operation is not completed, the process proceeds to step S410.

  In step S410, the client terminal 102 determines whether it is possible to work in the current arrangement work place by the same procedure as in step S302. If work is possible, the process proceeds to step S412. The process proceeds to S414.

  In step S412, the client terminal 102 determines whether a movement condition is set at the current location. For example, when the work place is a work place of a conveyor type (work place type is a conveyer type), there is a flow in a certain direction, and movement of the matching member should occur accordingly.

  If there is a movement condition, the process proceeds to step S414; otherwise, the target is the next operation, and the process returns to step S400.

  In step S414, the client terminal 102 executes movement of a member to be moved. The process related to the movement of the members will be described in detail with reference to FIG.

  In FIG. 7, the detailed process regarding the movement of a member is demonstrated.

  In step S500, the client terminal 102 determines whether the work has been completed by the same method as in step S400. If the work has been completed, the process proceeds to step S502. If the work has not been completed, the process proceeds to step S504. Proceed.

  In step S <b> 502, the client terminal 102 sets a movement destination of a member for which work has been completed. At this time, the completed item storage is set as the destination. The completed item storage area indicates a preset work place, and sets the work place ID of the work place.

  In step S504, the client terminal 102 determines whether or not a movement condition is set at the current location in the same procedure as in step S412. If the movement condition is not set, the process proceeds to step S506. If the movement condition is set, the process proceeds to step S508.

  In step S <b> 506, the client terminal 102 sets a movement destination of a member for which work has not been completed and for which the movement condition of the workplace is not set. At this time, the moving destination is selected at random from a work place where this member work can be performed.

  In step S <b> 508, the client terminal 102 sets the movement destination of a member for which the work condition has not been completed and for which the movement conditions of the workplace are set. At this time, the destination is the current workplace.

  After setting the movement destination in step S502, step S506, and step S508, whether or not the member can be moved is determined in steps S510 to S514.

  In step S510, the client terminal 102 determines whether there is sufficient space in the destination workplace. That is, it is determined whether the size and weight upper limit of the workplace are larger than the size and weight of the target member. If there is sufficient space, the process proceeds to step S512. If there is not enough space, the process proceeds to step S518. Proceed.

  In step S <b> 512, the client terminal 102 determines whether it is possible to secure transport means to the destination. If there is a heavy machine or the like that carries the target member from the movement source to the movement destination and is operable, it is determined with reference to the conveyance machine table (FIG. 12), and if the conveyance means can be secured, the process proceeds to step S514. If the transfer means cannot be secured, the process proceeds to step S516.

  The carrier table uses a carrier ID that uniquely identifies the carrier, the factory ID of the factory where the carrier is installed, the name of the carrier, the information indicating the range in which the member can be conveyed, and the member. Consists of the limit weight possible.

  As described above, the information indicating the range in which the member can be conveyed is, as described above, when the screen displayed on the display unit 210 of each client terminal 102 includes a rectangular display area, It is defined as an X-axis that is positive from the origin to the right, a Y-axis that is positive from the top, and a Z-axis that is positive upward from the origin, and consists of the X, Y, and Z axes. The range that can be transported is shown using the coordinates.

  For the movable range X, coordinate values that can be transported in the positive direction of the X axis, for the movable range Y, coordinate values that can be transported in the positive direction of the Y axis, and for the movable range Z, the positive value of the Z axis The coordinate value which can be conveyed with respect to the direction is shown.

  In step S514, the client terminal 102 determines whether or not it interferes with another member or the factory wall when the member is placed at the destination. The coordinate position calculation when the member is arranged in the work place of the movement destination is performed, and it is determined whether or not the interference between the members occurs from the size of the target member and the size of the member already arranged in the work place.

  Similarly, after calculating the movement destination coordinate position of the target member, it is determined whether or not interference with the factory wall occurs. If interference occurs, the process proceeds to step S518. If interference does not occur, step S516 is performed. Proceed to the process.

  In step S516, the client terminal 102 allows the target member to be placed at the destination, moves the member to the position calculated in step S514, and updates the work information and placement information of the member.

  In step S518, the client terminal 102 determines whether or not the current target member stays in the current work place for a long time. Specifically, if the difference between the current set time set in step S200 and the time set in the current work place exceeds the value specified by the system, it is determined to stay for a long time.

  At the same time, the movement destination that is the current target is not allowed to move, and the corresponding movement destination is stored. If it has stayed for a long time, the process proceeds to step S520. If it has not stayed for a long time, the member movement is terminated.

  In step S520, the client terminal 102 finds an empty work place (a work place other than the current work place) and moves the member that has stayed for a long time. As a result, there is a possibility that a member that cannot move to the current work site at a later stage can be moved.

  As a method for selecting a vacant place, it is possible to select from a factory and a work place ID in the work place table that do not correspond to the factory ID designated by the user and the work place ID of the work information.

  In step S518, the work areas except for the non-movable work place and the empty work place are set as movement candidates, and one of the movement candidates is selected at random and set as the movement destination. The process proceeds to S510.

  The movement process set via step S520 is called irregular movement in this embodiment, and the number of irregular movements in the evaluation value in step S120 is the number of movements generated in the work member arrangement plan. That is.
