The row deletion button 115 can be clicked by the user to delete the usage from any usage scenario. The execution button 116 can be clicked by the user to instruct the start of the area utilization planning process.

Hereinafter, the case where the area planning period and the area planning conditions shown in FIG. 10 are set will be described as an example.

Next, FIG. 11 is a flowchart illustrating an example of the area utilization planning process. FIG. 12 is a flowchart illustrating step S3 of FIG. 11 in detail. FIG. 13 is a flowchart illustrating step S5 of FIG. 11 in detail.

In the area utilization planning process of FIG. 11, for example, when the work area in the factory is tight and the production plan needs to be reviewed, it is necessary to consider how to use the empty space in the work area in the future. In some cases, the operation is started when the user sets necessary information on the input screen 110 (FIG. 10) and clicks the execute button 116.

The storage unit 200 contains the production plan information 211, the work area information 212, the area occupancy information 213, the area usage condition information 214, and the equipment power supply usage area information 215 shown in FIGS. 2 to 6 as input information 210. It is assumed that it has already been remembered.

First, the data acquisition unit 321 of the arithmetic processing unit 320 has input information 210 (production plan information) corresponding to the area planning period (in this case, "6/1" to "6/30") set on the input screen 110. 211, work area information 212, area occupancy information 213, area usage condition information 214, and equipment power supply usage area information 215) are acquired from the storage unit 200 and stored in the memory unit 310 (step S1).

Next, the planned production area extraction unit 322 extracts the work area and the period already scheduled to be used in the production plan based on the production plan information 211 and the area occupancy information 213 of the memory unit 310, and stores them in the memory unit 310 (. Step S2).

Specifically, the planned production area extraction unit 322 extracts the product code and the process from the production plan information 211 (FIG. 2) in the order of the earliest start date, and also extracts the product code and the process based on the area occupancy information 213 (FIG. 4). Extract the product code and the work area occupied when carrying out the process and the area thereof. Further, the planned production area extraction unit 322 groups the processes to be performed in the same work area on the same start date, assigns a production event number, generates production event information 3221 (FIG. 14), and generates the production event information 3221 (FIG. 14) in the memory unit 310. Store.

FIG. 14 shows an example of the production event information 3221 generated in step S2. In this case, for example, since the start date "6/1" and the work area "E10" of the "test" process of the product "P10" and the "assembly" process of the product "P11" are the same, the same production is performed. The event number "1" is given. Further, since the "shipping" process is not stored in the area occupancy information 213 (FIG. 4), it does not occupy the area of the work area. Is recorded as "0". The "shipping" process means that the product of the product "P10" disappears from the work area "E10".

Next, the available area determination unit 323 pays attention to the area use scenarios set on the input screen 110 in numerical order, and pays attention to the production event numbers in order for the area use scenarios of interest, and the memory. For the empty space of each work area for each production event in the work area information 212 (FIG. 3) of the unit 310, the availability for each period and use is determined, and the use, period, and area are assigned to the work area (step S3). ).

The detailed processing of step S3 will be described with reference to FIG.

First, the available area determination unit 323 identifies the work area corresponding to the production event number of interest in the production event information 3221 (FIG. 14) stored in the memory unit 310, and works on the size of the work area. Obtained from the area information 212 (FIG. 3), the area of each process in the production event is allocated to the work area, and the usage allocation information 2221 (FIG. 16) is generated and stored in the memory unit 310 (step S31).

Specifically, the available area determination unit 323 pays attention to the production event number "1" in the production event information 3221, and since the work area is "E10", the work area "E10" is obtained from the work area information 212. As the size of "", the vertical width "7 [m]" and the horizontal width "10 [m]" are acquired. Then, the available area determination unit 323 allocates the planned production area scheduled to be used on the start date "6/1" in the work area "E10" to the work area "E10" based on the production event information 3221 (FIG. 14). .. FIG. 15 shows a state in which the planned production area (the area of the “test” process of the product “P10” and the area of the “assembly” process of the product “P11”) to be used are allocated to the work area “E10”. ing. Then, the available area determination unit 323 generates the usage allocation information 2221 (up to the first and second lines in FIG. 16) using the allocation result as data.

Next, based on the area usage condition information 214 (FIG. 5) and the equipment power supply usage area information 215 (FIG. 6), the available area determination unit 323 pays attention to the work area in the area usage scenario. Focusing on each application in order of priority, the start point of the empty space (rectangular area having a width of 2 [m] or more in length and width) is searched (step S32), and it is determined whether or not the start point of the empty space can be searched (step S33). ). Here, when it is determined that the available area determination unit 323 has been able to search for the start point of the empty space (YES in step S33), the process proceeds to step S34. On the contrary, when the available area determination unit 323 determines that the start point of the empty space cannot be searched (NO in step S33), the process proceeds to step S37.

Specifically, in the input screen 110 (FIG. 10), the area usage scenario "ES01" of interest is set only for "assembly" use, and when the area usage condition information 214 (FIG. 5) is referred to, Since no equipment, power supply, and partition are required for "assembly" applications, the position of the equipment and power supply is not considered, and the work area "E01" is located in the Y and X directions from the upper left origin (1,1). Search for the starting point of the empty space in sequence.

In the case of the work area "E10" shown in FIG. 15, since the origin (1,1) is vacant, the available area determination unit 323 determines the origin (1,1) as the start point of the vacant space.

Next, the available area determination unit 323 searches for the end point of the widest empty space starting from the origin (1,1) (step S34). In the case of the work area "E10" shown in FIG. 15, (10, 2) is determined as the end point of the widest empty space starting from the point (1, 1). In this case, the size of the empty space is 10 × 2 [m].

Next, the available area determination unit 323 determines whether or not the empty space determined in steps S32 and S34 can be used for each purpose (step S35). Here, if the available area determination unit 323 determines that it is available, the process proceeds to step S36. On the contrary, when the available area determination unit 323 determines that the available area cannot be used, the process is returned to step S32, and the processes after step S32 are repeated for the next use.

In this case, from the area usage condition information 214 (Fig. 5), it can be seen that the minimum size of the area required for "assembly" use is 2 x 2 [m], and the empty space is 10 x 2 [m]. Therefore, the available area determination unit 323 determines that the empty space can be used for "assembly" purposes.

Next, the available area determination unit 323 allocates the usage, area, and start date to the empty space determined to be available, and updates the usage allocation information 2221 of the memory unit 310 based on the result (). Step S36). Specifically, the data in the third line of the usage allocation information 2221 shown in FIG. 16 is added.

The item of the allocation flag in the usage allocation information 2221 (FIG. 16) stores "1" when the product to be specifically produced is determined. On the contrary, when the product to be produced is not decided, that is, when the usage is an allocated empty space, "0" is stored, and the product code starting with "F" is stored as a dummy value in the product column.

After that, the process returns to step S32, and steps S32 and subsequent steps are repeated to further search and allocate an empty space in the work area "E01", and the usage allocation information 2221 4 shown in FIG. , The 5th line is added.

FIG. 17 shows the allocation state of the area in the work area “E10” corresponding to the 1st to 5th lines of the usage allocation information 2221 shown in FIG. That is, in the figure, with respect to the work area "E10", the area of the "test" process of the product code "P10" and the area of the "assembly" process of the product code "P11" are the areas of the planned production to be used. Areas that have been assigned and have not been reserved for use include the "assembly" process area of the product code "F01", the "assembly" process area of the product code "F02", and the "assembly" process of the product code "F03". The state in which the area of is allocated is shown in the figure. The rectangular area of the start point (10, 3) and the end point (10, 7) shown in the figure has a width of less than 2 [m] and is not detected as an empty space, so that it cannot be assigned to any purpose. ..

After that, the available area determination unit 323 determines whether or not the use of the area use scenario currently being focused on remains unfocused (step S37). Then, when it is determined that there is a remaining use that has not been focused (YES in step S37), the process is returned to step S32, and the next step S32 and subsequent steps are repeated focusing on the next highest priority use. Then, when it is determined that there is no use that is not of interest (NO in step S37), the available area determination unit 323 ends the detailed processing of step S3.

In this case, only the "assembly" use is set in the area use scenario "ES01", and there is no other use. Therefore, the available area determination unit 323 performs detailed processing in step S3 for the area use scenario "ES01". To finish. Then, the process proceeds to step S4 of FIG.

Next, the available area determination unit 323 determines whether or not a production event not of interest remains in step S3 (step S4), where the available area determination unit 323 does not pay attention to the production. If it is determined that an event remains (YES in step S4), the process proceeds to step S5. On the contrary, when the available area determination unit 323 determines that there are no unfocused production events remaining (NO in step S4), the process proceeds to step S6.

In this case, as is clear from the production event information 3221 (FIG. 14), the production event numbers in the area planning period (“6/1” to “6/30”) exist from “1” to “5”. Since no attention is paid to the production event number “2” or later, the process proceeds to step S5.

Next, the overlapping area determination unit 324 determines the overlap of the area and the period allocated to the empty space as the area usage scenario for the next work area and the period scheduled to be used, and the result of the overlap determination is Based on this, the usage allocation information 2221 (FIG. 16) is updated (step S5).

The detailed processing of step S5 will be described with reference to FIG.

First, the overlapping area determination unit 324 acquires the production event information 3221 (FIG. 14) and the usage allocation information 2221 (FIG. 16) from the memory unit 310 (step S51). In this case, attention is paid to the data of the production event number "2" of the production event information 3221. The data indicate that the start date of the "assembly" process for product "P12" is "6/4". Furthermore, focusing on the data of the previous production event number "1", since the end date of the "test" process and the "assembly" process is "6/8", the figure at the time of "6/4" is shown in the figure. As shown in 18, it can be seen that the products “P10” and “P11” corresponding to the production event number “1” also exist in the work area “E10”.

Therefore, the overlapping area determination unit 324 adds and updates the data in the sixth line corresponding to the data of the production event number “2” to the acquired usage allocation information 2221 (FIG. 16), thereby providing usage allocation information. 2222 (FIG. 19) is generated and stored in the memory unit 310.

FIG. 19 shows the updated usage allocation information 2222. The data in the 6th line of the usage allocation information 2222 is the period from the start date "6/4" to the end date "6/13" in the "assembly" process of the product "P12", the start point (1,5), and the end point ( It shows that it occupies the area of 4, 6).

Next, the overlapping area determination unit 324 refers to the usage allocation information 2222 (FIG. 19), and allocates the planned use area (data of the allocation flag “1”) and the allocation result of the empty space (data of the allocation flag “0”). And, and it is determined whether or not there is an overlapping area (step S52). Here, when the overlapping area determination unit 324 determines that there is an overlapping area (YES in step S52), the process proceeds to step S53. On the contrary, when the overlapping area determination unit 324 determines that there is no overlapping area (NO in step S52), the detailed processing in step S5 is terminated.

In the present case, the overlap determination in step S52 substantially compares the state of the work area “E10” shown in FIG. 17 with the state of the work area “E10” shown in FIG. .. As is clear from the comparison between FIGS. 17 and 18, the area of the “assembly” process of the product “F02” and the area of the “assembly” process of the product “P12” overlap, so that the process is performed in step S53. It can be advanced.

Next, the overlapping area determination unit 324 was blank so as not to cause duplication in the allocation result (data of the allocation flag "0") of the empty space of the overlapping usage allocation information 2222 (FIG. 19). Set the date on the end date. In this case, duplication occurs after "6/4", so "6/3" is set as the end date of the third line of the usage allocation information 2222, which is the day before the overlapping day.

Next, the overlapping area determination unit 324 determines whether or not the empty space for which the end date is set satisfies the required minimum period for each application (step S54). Here, when the overlapping area determination unit 324 determines that the required minimum period is satisfied (YES in step S54), the detailed processing in step S5 is terminated. On the contrary, when the overlapping area determination unit 324 determines that the required minimum period is not satisfied (NO in step S54), the allocation result of the empty space that does not satisfy the required minimum period is deleted (step S55).

In this case, the minimum required period for the "assembly" process of the product code "F02" for which the end date is set is "10 (day)" according to the area usage condition information 214 (FIG. 5). On the other hand, the "assembly" process of the product code "F02" can only be assigned for 3 days from the start date "6/1" to the end date "6/3", and the minimum required period is not met. Therefore, the data related to the product code "F02" on the third line from the usage allocation information 2222 (FIG. 19) is deleted.

This completes the detailed processing of step S5 corresponding to the production event number “2”. Then, the process is returned to step S3 in FIG.

Next, by repeating steps S3 to S5, the overlapping area determination unit 324 sequentially pays attention to the production event numbers "3" to "5" in the production event information 3221 (FIG. 14) and performs detailed processing in step S5. Run. As a result, the allocation state in the work area "E10" changes as shown in FIG. The usage allocation information 2222 (FIG. 19) is also updated by the overlapping area determination unit 324, and the data corresponding to the usage scenario "ES01" in the area usage layout information 222 (FIG. 8) (lines 1 to 10 in FIG. 8). (Eye data) is generated and stored in the memory unit 310.

For example, in the state corresponding to the production event number “3” in FIG. 20, the area of the start point (5,5) and the end point (10,7) is temporarily allocated to the “assembly” use of the product “F05”. Since it overlaps with the area of the "test" process of the product "P12" in the next production event number "4" and does not meet the required minimum period, the corresponding data is from the area usage layout information 222 (FIG. 8). It has been deleted.

After that, the available area determination unit 323 determines that the production event number “6” in the production event information 3221 (FIG. 14) has a start date after the area planning period, so that no production event not focused on in step S3 remains. (NO in step S4), and the process proceeds to step S6.

Next, the available area determination unit 323 determines whether or not an unfocused area use scenario remains among all the area planning conditions set on the input screen 110 (step S6). Here, when the available area determination unit 323 determines that there is an area utilization scenario that is not of interest (YES in step S6), the process is returned to step S3.

In this case, the area usage scenario "ES01" is focused on, and the area usage scenarios "ES02" to "ES04" remain without attention. Therefore, the available area determination unit 323 next determines the area usage scenario "ES02". Focusing on "ES02", steps S3 to S6 are executed.

In the case of the area use scenario "ES02", according to the input screen 110 (FIG. 10), it can be seen that the priority order of the "test" use and the "assembly" use is set. The detailed processing of step S3 when focusing on the area usage scenario “ES02” will be described with reference to the flowchart of FIG.

First, the available area determination unit 323 identifies the work area "E10" corresponding to the production event number "1" of interest from the production event information 3221 (FIG. 14), and from the work area information 212, the work area " The size (10 × 7 [m]) of “E10” is acquired. Then, the available area determination unit 323 allocates the planned production area scheduled to be used on the start date "6/1" in the work area "E10" to the work area "E10" based on the production event information 3221 (FIG. 14). (Step S31).

Next, based on the area usage condition information 214 (FIG. 5) and the equipment power supply usage area information 215 (FIG. 6), the available area determination unit 323 pays attention to the work area in the area usage scenario. Focusing on each application in order of priority, the starting point of the empty space is searched for (step S32).

Specifically, in the case of the area use scenario "ES02", the area use plan is formulated in the order of "test" use and "assembly" use, but according to the area use condition information 214 (Fig. 5), "test". The application requires a "400V" power supply. Therefore, the available area determination unit 323 refers to the equipment power supply usage area information 215 (FIG. 6), and the start point (4, 2) and the end point (9, 2,) in which the "400V" power supply can be used in the work area "E10". Specify the range of 7) and allocate free space for "test" use only to this range. The state of the work area "E10" at this point is as shown in FIG. 21, and the inside of the thick broken line is the area that can be used for "test", that is, the range in which the "400V" power supply can be used. The start point (4, 2) of the range is determined as the start point of the empty space for the "test" use (YES in step S33). Then, the end point (5, 7) that can secure the maximum free space with respect to the start point (4, 2) of the empty space is searched for and determined (steps S33, S34).

Next, the available area determination unit 323 refers to the area usage condition information 214 (FIG. 5), and the required minimum size (2 × 2 [m]) for the “test” application and the size of the empty space (2 ×). 6 [m]) is compared to determine that the empty space is available for "test" use (YES in step S35). Next, as shown in FIG. 22, the available area determination unit 323 uses the use “test”, the start point (4, 2), and the end point (5, 7) areas for the empty space determined to be available. And the start date "6/1" is assigned, and the usage allocation information (not shown) is generated and stored in the memory unit 310.

After that, the process returns to step S32, and steps S32 to S36 are repeated. However, since there is no more free space available for the "test" application, the process proceeds to step S37, and the available area determination unit 323 determines. Among the uses of the area use scenario "ES02" of interest, it is determined whether or not there are still uses of interest that are not of interest (step S37). In this case, since there are still "assembly" applications that are not of interest (YES in step S37), the process is returned to step S32, and by focusing on the "assembly" application and repeating steps S32 and subsequent steps, FIG. 22 shows. For the indicated work area "E01", the "assembly" use area of the product "F02", the "assembly" use area of the product "F03", and the "assembly" use area of the product "F04". The allocation is added, and the allocation state of the work area "E01" is as shown in FIG. 23. Then, the usage allocation information 2223 shown in FIG. 24 is generated and stored in the memory unit 310. Then, the process proceeds to step S4 of FIG.

Next, the available area determination unit 323 determines that there are still production events not of interest in step S3 (YES in step S4), and the process returns to step S3 via step S5.

After that, the available area determination unit 323 pays attention to the production event numbers “2” to “5” in order, and steps S3 to S5 are repeated. As a result, the state of allocation to the work area "E10" changes as shown in FIG. 25. The usage allocation information 2223 (FIG. 24) is also updated by the overlapping area determination unit 324, and the data corresponding to the usage scenario "ES02" of the area usage layout information 222 (FIG. 8) (data on the 11th to 22nd lines). ) Is generated and stored in the memory unit 310.

After that, the available area determination unit 323 determines that there are no production events not of interest in step S3 (NO in step S4), and the process proceeds to step S6.

Next, the available area determination unit 323 determines that there is an area utilization scenario that is not of interest (YES in step S6), and the process is returned to step S3.

In this case, the area usage scenario "ES02" is attracting attention, and the area usage scenarios "ES03" and "ES04" remain. Therefore, next, the available area determination unit 323 determines the area usage scenario "ES03", Focusing on "ES04" in sequence, steps S3 to S6 are executed.

As a result of the available area determination unit 323 paying attention to the area use scenario "ES03" and executing steps S3 to S6, the state of allocation to the work area "E10" changes as shown in FIG. 26. The usage allocation information 2223 (FIG. 24) is also updated by the overlapping area determination unit 324, and the data corresponding to the usage scenario "ES03" of the area usage layout information 225 shown in FIG. 28 (lines 1 to 12). Data) is generated.

Next, as a result of the available area determination unit 323 paying attention to the area use scenario "ES04" and executing steps S3 to S6, the state of allocation to the work area "E10" changes as shown in FIG. 27. The usage allocation information 2223 (FIG. 24) is also updated by the overlapping area determination unit 324, and the data corresponding to the usage scenario "ES04" of the area usage layout information 225 shown in FIG. 28 (lines 13 to 23). Data) is generated.

Next, the area utilization plan generation unit 325 generates the area utilization plan information 221 (FIG. 7) based on the area utilization layout information 222 and 2225 generated so far, and stores the area utilization plan information 221 (FIG. 7) in the memory unit 310 (step S7).

Specifically, in this case, the area usage plan generation unit 325 has the area usage layout information 222 (FIG. 8) corresponding to the area usage scenarios "ES01" and "ES02", and the area usage scenarios "ES03" and "ES04". The area usage layout information 2225 (FIG. 28) corresponding to the above is acquired from the memory unit 310. Then, the area utilization plan generation unit 325 extracts the data whose allocation flag is "0" from the data of the area utilization layout information 222, 2225, and determines the size of the available area based on the start point and the end point of each data. By calculating, the area utilization plan intermediate information 2211 shown in FIG. 29 is generated.

Further, the area utilization plan generation unit 325 aggregates the available areas in chronological order according to the work area, usage scenario, and usage of the area utilization plan intermediate information 2211 (FIG. 29), so that the area utilization plan information 221 (FIG. 7) is obtained. To generate.

For example, in the "assembly" application of the work area "E10" in the area utilization plan intermediate information 2211 (FIG. 29) and the area utilization scenario "ES01", the period from "6/1" to "6/8" is the product "F01". , The available area of "F03" can be totaled, and the totaled result "26 [m ² ]" is described in the first line of the area usage plan information 221 (FIG. 7). In addition, in the "assembly" use of the work area "E10" and the area usage scenario "ES01", the products "F01", "F03", and "F04" can be used during the period from "6/9" to "6/13". Areas can be aggregated, and the aggregation result "30 [m ² ]" is described in the second line of the area utilization plan information 221 (FIG. 7). Furthermore, in the "assembly" application of the work area "E10" and the area usage scenario "ES01", the products "F01", "F03", "F04", "F06" are used during the period from "6/14" to "6/20". The available area of "" can be totaled, and the totaled result "45 [m ² ]" is described in the third line of the area usage plan information 221 (FIG. 7). Furthermore, in the "assembly" use of the work area "E10" and the area usage scenario "ES01", the products "F01", "F03", "F04", "F04", "F01" during the period from "6/21" to "6/30" The usable areas of "F06" and "F07" can be totaled, and the totaled result "55 [m ² ]" is described in the fourth line of the area usage plan information 221 (FIG. 7).

Next, the area utilization rate calculation unit 326 is time-series for each work area based on the area utilization plan information 221 (FIG. 7) and the area utilization layout information 222 (FIG. 8) and 2225 (FIG. 28) generated in step S7. The area utilization area is calculated, and the area utilization rate information 223 (FIG. 9) is generated based on the work area information 212 (FIG. 3) and stored in the memory unit 310 (step S8).

Specifically, in this case, the area utilization plan generation unit 325 extracts the data whose allocation flag is "1" from the data of the area utilization layout information 222, 2225, and is based on the start point and the end point of each data. By calculating the size of the available area, the area utilization plan intermediate information 2212 shown in FIG. 30 is generated. At this time, for data having the same work area, product, use, start date, and end date but different usage scenarios, only one data is left and the other data is deleted.

Further, the area utilization plan generation unit 325 calculates the time-series area utilization area for each area utilization scenario based on the area utilization plan intermediate information 2212 (FIG. 30) and the area utilization plan information 221 (FIG. 7). Area utilization rate intermediate information 2231 (FIG. 31) is generated.

For example, for the area usage scenario "ES01", the usable area of "6/1" to "6/3" is "24 (= 20 + 4) [m ² ]" from the area usage plan intermediate information 2212 (FIG. 30). From the area usage plan information 221 (Fig. 7), it can be seen that the usable area of "6/1" to "6/3" is "26 [m ² ]", so this total value. “56 [m ² ]” is described in the first line of the area utilization intermediate information 2231 (FIG. 31). Further, from the area utilization plan intermediate information 2212 (FIG. 30), it was found that the usable area of "6/4" to "6/8" is "32 (= 20 + 4 + 8) [m ² ]", and the area utilization plan From the information 221 (FIG. 7), it can be seen that the usable area of "6/4" to "6/8" is "26 [m ² ]", so this total value "58 [m ² ]" is used as the area. It is described in the second line of the utilization rate intermediate information 2231 (FIG. 31). Further, from the area utilization plan intermediate information 2212 (FIG. 30), it was found that the usable area of "6/9" to "6/13" is "16 (= 8 + 8) [m ² ]", and the area utilization plan From the information 221 (FIG. 7), it can be seen that the usable area of "6/9" to "6/13" is "30 [m ² ]", so this total value "46 [m ² ]" is used as the area. It is described in the third line of the utilization rate intermediate information 2231 (FIG. 31).

Furthermore, the area utilization plan generation unit 325 aggregates the area utilization area of the area utilization rate intermediate information 2231 (FIG. 31) for each area utilization scenario, and the work area "E10" that can be seen from the work area information 212 (FIG. 3). By dividing by the area (70 [m ² ]) × the area planning period (30 days (6/1 to 6/30)), the area utilization rate is calculated and the area utilization rate information 223 (FIG. 9) is generated.

For example, for the area usage scenario "ES01", when the area usage area of the area usage scenario "ES01" is totaled from the area usage rate intermediate information 2231 (FIG. 31), 1795 (= 50 x 3 + 58 x 5 + 46 x 5 + 65 x 7 + 67 x 10). ) [M ² ], and when divided by 2100 (= 70 × 30) [m ² ], it becomes 0.855.

Further, for example, for the area usage scenario "ES02", when the area usage area of the area usage scenario "ES02" is totaled from the area utilization rate intermediate information 2231 (FIG. 31), 1719 (= 46 × 3 + 54 × 5 + 44 × 5 + 63 × 7 + 65 × 10) It is [m ² ], and when divided by 2100 (= 70 × 30) [m ² ], it becomes 0.819.

Finally, the display control unit 327 stores the area utilization plan information 221 (FIG. 7), the area utilization layout information 222 (FIG. 8), and the area utilization rate information 223 (FIG. 9) stored in the memory unit 310. Is output to and stored as output information 220. Further, the display control unit 327 generates an output screen 120 (FIG. 32) based on the area usage plan information 221 and the area usage layout information 222, and the area utilization rate information 223, outputs the output screen 120 (FIG. 32), outputs the output to the input / output unit 100, and inputs / outputs. It is displayed on the display of the unit 100 (step S9). This completes the area usage planning process.

Next, FIG. 32 shows a display example of the output screen 120. The output screen 120 is provided with a planning period display column 121, an area utilization plan display column 122, an area utilization rate display column 123, and an area utilization layout display column 124.

In the planning period display field 121, the area planning period input by the user to the input screen 110 is displayed. In the area usage plan display column 122, a schedule table showing the area of the available area in each period and the planning table for each work area, usage scenario, and usage based on the area usage plan information 221 (FIG. 7) are displayed. .. As a result, the user can grasp the area of the usable area for each usage for the period of each usage scenario, and can consider the usage scenario for the shortage of the area of each process.

In the area utilization rate display column 123, the area utilization rate for each usage scenario based on the area utilization rate information 223 (FIG. 9) is displayed. As a result, the user can grasp the area utilization rate for each usage scenario, and can consider the usage scenario for efficiently using the area.

In the area usage layout display field 124, the usage layout of the work area based on the area usage layout information 222 (FIG. 8) is displayed. In the area usage layout display field 124, the user can select or input a work area, a usage scenario, and a date on which the usage layout is displayed. In addition, the user can select a use and highlight the area allocated to the selected use.

In the case of the figure, the area usage layout display column 124 displays the usage layout corresponding to the work area "E01", the usage scenario "ES02", and the date "6/21", and the area for "test" is displayed. It is highlighted. This enables the user to formulate a concrete execution measure for an area shortage or the like.

<Summary>
According to the area utilization planning process explained above, in a factory that produces large-scale products that require a work area, the empty space over time in the future can be used for actual manufacturing, testing, area rental, etc. It becomes possible to make an area utilization plan. As a result, even in a situation where the work area becomes a bottleneck in production planning, efficient product production can be efficiently planned and executed, so that the production lead time can be shortened. Furthermore, since it is possible to confirm the feasibility of external lending of the work area in the future without affecting the production plan in the factory, it is possible to effectively utilize the work area in the factory.
