[0002]

2. Description of the Related Art When allocating a large variety of small quantity processed parts (hereinafter abbreviated as parts) to each processing facility / worker to perform processing on the parts, the parts can be created by various methods such as creating a Gantt chart. Is assigned to each processing facility / worker.

However, in these allocation methods,
If an urgent item enters the processing shop (site) or parts are out of sync, the production plan will be disrupted. For this reason, it is very difficult to apply various allocation methods to such a processing shop, and moreover, it becomes more difficult under flextime because a flexible processing time zone condition is added.

The above-mentioned various methods can be applied only under the condition that the order of allocating the parts to the processing equipment is limited. However, it is very difficult to apply because the processing shop to be applied has many conditions as follows. That is, (a) there is a component allocation priority condition that prioritizes components that are likely to be delayed.

(B) There is a component allocation priority condition that prioritizes delayed components. (c) There is a component allocation priority condition that prioritizes emergency products. (d) There are conditions such as parts synchronization and delivery priority.

(E) There is a condition that a worker has a large number of units. (f) There are conditions to improve the operating rate by grouping similar parts. (g) There are conditions for load leveling.

(H) Under flextime, there are flexible processing time zones (by equipment and worker). (i) There are conditions for down equipment and adjustment of processing capacity for absentee workers.

(J) There are conditions for adjusting the processing capacity of the processing equipment / workers when the production load is over (adjusting the capacity frame due to an increase in the number of equipment / workers, overtime, postponing delivery). On the other hand, there is a method of expanding the limited conditions of the above method, but since this is a method of extracting the order satisfying the conditions from all combinations of the allocation order, a huge amount of time is required for the calculation using the EWS and the personal computer.

For this reason, the calculation cannot keep up with the changes in the above-mentioned conditions of the processing shop, which makes it difficult to apply. Because of this, the allocation (mounting) of parts to the first processing equipment that limits conditions such as parts synchronization and delivery priority has been automated, but reallocation including many conditions (mountain collapse: scheduling) , I hold a process meeting and do it manually. This precludes accurate and timely scheduling that matches the capabilities of the processing shop.

[0010]

As described above, according to the conventional method, it is very difficult to satisfy many conditions and schedule in a short time. Therefore, in order to prevent the production plan from collapsing, it is necessary to manually adjust the plan, that is, to perform rescheduling: mountain collapse.

Further, due to human labor, highly accurate and timely scheduling corresponding to the capability of the processing shop cannot be performed. Unable to perform timely scheduling under flextime.

[0012] Therefore, an object of the present invention is to provide a high-speed, high-accuracy, highly flexible load leveling scheduling apparatus that prevents plan collapse. Another object of the present invention is to provide a scheduling device that can automate rescheduling. Another object of the present invention is to provide a scheduling device capable of setting a flexible processing capacity corresponding to flextime.

(A) to (n) indicate the order of expansion of processing capacity (small to large). [Case 1] and [Case 2] in the menu represent a triple processing capability adjustment loop (repeating range) when the level equalization is specified. The right side loop is meant to be included on the right side. From this loop, the expansion order of the processing capabilities (on the right side of the figure) is calculated.

The machining load allocating unit 8 for a component (hereinafter, abbreviated as "multi-machine allocating unit") 8 having a large number of units is in charge of the worker according to the capability of the worker in the processing facility / worker capability data D4. It has a function that allocates the processing load to multiple general-purpose machines that enable it to have multiple processing facilities.

For example, as shown in FIG. 11, workers A and B
Both take charge of the lathe EL and the milling machine VM, if the load of the lathe EL is higher than that of the milling machine VM, the worker A
The load on the lathe EL of No. 1 is transferred to the load of the lathe EL of the worker B to equalize the machining load.

Uses the processing load data for each equipment / worker assigned to the processing time frame, which is the frame of the processing capacity for each equipment / worker.
It has a function of outputting and displaying the schedule data Q1 and the processing equipment / worker load data Q2 on a data display device.

The schedule data Q1 is machining load data assigned in time series according to the machining order of the parts in units, and the machining equipment / worker load data Q2 is a plurality of parts assigned to each machining equipment / worker. This is the processing load data for the same equipment / operator.

After execution of the scheduling, the rescheduling unit 10 performs the actual machining work according to the planned machining start date and the planned machining end date in the schedule data Q1. If the actual processing end date is entered and the actual processing start date is not entered even if the scheduled start processing date has passed, or if the actual processing end date has not been entered even after the expected processing end date has passed, the Judging that some parts are late,
It has a function of assigning the highest priority re-partition to the part, that is, re-scheduling.

The rescheduling unit 10 has a function of allocating parts in order of earliest delivery date when there are a plurality of parts whose machining start and machining end dates have passed. Further, the rescheduling unit 10 has a function of displaying a warning on the data display device of the terminal for each part for which the delivery date is exceeded.

Next, the operation of the device configured as described above will be described. The scheduling engine 1 uses the data input device to assign the component allocation priority order data D1, the component machining load data D3, and the machining capability adjustment priority order data D.
6. Input the processing equipment / worker capability data D4, etc., arrange multiple parts according to the part allocation priority order and grouping classification, and specify the processing load from the first part in that order according to the part delivery date or start date. The data is allocated at allocation intervals, and as a result, the schedule data Q1 and the processing equipment / worker load data Q2 are output and displayed on the data display device.

The operation of the scheduling engine 1 will be described below. The priority order setting unit 2 creates a menu using the start-of-work rule, urgent goods rule, control process rule, other section passing rule, and other rules as part allocation priority order rule data, and displays and outputs the menu on the data display device.

FIG. 13 is a diagram showing selection of a scheduling rule using a menu displayed and output on the data display device. Therefore, the operator selects the displayed menus in order to set the priority order of component allocation according to the selection order of the menus.

As a result, the priority order setting unit 2 uses the parts allocation priority order data D1 which is the rule data for keeping the delivery date of the parts, and sequentially arranges the parts group within the designated schedule period. And set the allocation order of parts.

Further, the priority order setting unit 2 allocates the equipment / worker-specific machining load of the parts to the machining equipment / workers according to their capabilities according to the setting order of the priority order of the parts allocation.
The assigning unit 4 of the set interval sets the processing load for each equipment / worker.
Allocate to the equipment and workers according to their capabilities.

At this time, the allocating unit 4 of the set interval displays the allocating interval between the equipment and the worker as a menu shown in FIG. 13 and indicates the interval selected by the menu, that is, the component allocating interval D5. So, 1/1 day: 1 day is 8 hours, once every 8 hours, 1/2 day: 1 day is 8 hours, once every 4 hours, 1/4 day: 1 day is 8 hours Allocate once every 2 hours, 1/8 day: 1 hour as 8 hours and once every hour.

For example, even in the case of overtime work, 2 shifts (16 hours), and 3 shifts (24 hours), the set interval with one day as 8 hours is applied. For example, in the case of 3 shifts, the set interval is 1
/ On the 8th day, allocate 24 times every 24 hours (once every hour).

The machining time allocating unit 5 allocates the machining load by equipment / worker to the machining time zone of the machining equipment / worker according to the allocation interval data D5 between the equipment / workers, and performs appropriate scheduling.

The processing time allocating section 5 holds a frame of 1 day / maximum of 24 hours as the processing time zone when setting the frame of the processing capability corresponding to the processing time zone, as shown in FIG.
It has a machining load allocation location that corresponds to the hour of the hour, and allocates the machining load to the arbitrary machining time zone of the machining equipment / worker in the hour unit.

For example, when the working capacity frame of the worker and the general-purpose machine with a worker efficiency of 75% is set in the working time zone from 13:00 to 17 hours on a certain day, five work hours corresponding to the hour are displayed. The processing load allocation location is used, and the processing capacity of each location is a maximum value of 1 hour multiplied by 75% (0.75 hours).

As described above, the processing capacity corresponding to the processing time zone can be arbitrarily set according to the work system of the processing site. Further, the machining time allocating unit 5 allocates the machining load for each equipment / worker to the machining time zone, that is, the machining load allocation according to the allocation interval data D5 between the equipment / workers as shown in FIG. Scheduling is performed by load leveling by evenly allocating to locations.

For example, when the equipment / worker-specific machining load of the part P with an allocation interval of 1/2 day is allocated to two equipment / worker-specific machining capacity frames, the magnitudes of the machining loads (a) to (d) Switch the allocation method by.

(A) Size to be included in the machining capacity frame for each location First, in the machining capacity frames of the locations "1" to "4", allocation is made to the frame of the minimum machining capacity of the integrated value of the machining load,
Next, similarly, the processing capacity frames of the locations "5" to "8" are allocated to the target. If there is no free capacity in the four locations, shift to the next four locations and allocate them.

(B) Size within the allocation interval (locations "1" to "4", "5" to "8") First, within the machining capacity frame of locations "1" to "4", continuous Allocation is made to the machining capacity frame having a vacancy in the total of the locations to be processed, and then the machining capacity frames from the locations "5" to "8" are similarly allocated.

If there is a vacancy in the capacity of the four locations but no vacancy in the continuous locations, the existing machining load is shifted forward in units of location within the allocation interval and vacant. Make and allocate the vacancy.

(C) Size exceeding the allocation interval, but within the frame of one day (8 hours) Allocation is made to the frame of machining capacity with which the capacity of continuous locations is free. If there is no vacancy in the ability, it is sequentially shifted in units of allocation intervals to search for vacancy and allocation.

(D) Size exceeding the frame of one day Allocate to the frame of the machining capacity that has the vacancy in the capacity of continuous locations. If there is no vacancy in the ability, it is sequentially shifted in units of allocation intervals to search for vacancy and allocation.

The ascending / descending order allocating section 6 outputs and outputs as a menu either the ascending order allocation with an emphasis on component tuning or the descending order with an emphasis on parts delivery, and displays either one of the displayed menus. Are selected by the worker to be assigned in ascending or descending order.

The ascending / descending order allocating section 6 allocates in the direction in which time elapses on the basis of the component start date or the scheduled component delivery date, whichever is later, when the ascending order "later" is designated. , When descending order "advanced" is specified, the parts are delivered in the reverse direction based on the delivery date of the parts.

As described above, this allocation method is divided into the following four, based on the relationship between the scheduling start date, the part start date and the part delivery scheduled date, whichever is later, or the part delivery date. (a) Descending order “Advance” a-1: Normal case As shown in FIG.
Allocates in the descending order "advanced" at the specified allocation interval. If the parts start date is exceeded, the allocation interval is shifted by one step and allocated.

A-2: When the scheduling start date is after the parts start date and the scheduled parts delivery date As shown in FIG. 7, from the parts delivery date to the scheduling start date, descending order "advanced" at the specified allocation interval Allocate.

(B) Ascending order "Postponement" b-1: Normal case As shown in FIG. 8, the parts are designated from the later of the date when the parts are started and the day after the parts are scheduled to be delivered, toward the parts deadline. Allocate in ascending order "later" at the allocation interval.

B-2: When the scheduling start date has passed the parts start date and the scheduled parts delivery date, as shown in FIG. 9, from the scheduling start date to the parts delivery date, in ascending order at the designated allocation interval, "postponed" Assign to.

When the equipment / worker-specific machining load of parts exceeds the machining capacity, the machining capacity adjusting unit 7 uses the machining capacity adjustment priority order data D6 to perform the following three capacity adjustments. (a) Expand the capacity from the current worker group to other worker groups with priority 3 according to the degree of processing load.

(B) Overtime work expands the daily capacity. (c) To extend the capacity by extending the period while leveling the processing load. That is, the processing capacity adjustment unit 7 displays the processing capacity adjustment priority order shown in FIG. 10 as a menu on the data display device of the terminal, and receives the menu selection to perform the capacity adjustment.

The processing capacity adjusting section 7 has three methods as the capacity adjusting method, namely, the leveling of work groups (to another work group), the expansion of capacity limits (overtime), and the leveling of periods (delay of delivery date). And gradually expand the capacity by combining these methods.

Among these, the priority of the capability adjustment for leveling the work groups and expanding the capability frame is high, and when one has the first priority, the other has the second priority. Period leveling has the lowest priority.

The processing capacity adjusting unit 7 automatically adjusts the capacity at the final stage by the period leveling when the capacity adjustment up to the previous stage is insufficient regardless of whether the processing capacity adjustment priority order is selected or not. To implement.

Further, the machining capacity adjusting section 7 has three levels of capacity adjusting capacity for leveling the work groups, and the first priority work group to the third priority work group are selected according to the degree of the processing load. Capacity will be expanded sequentially.

The multi-machine allocating section 8 allocates a machining load to a plurality of general-purpose machines in charge of the worker according to the capability of the worker in the processing facility / operator capability data D4. For example, when the workers A and B are both in charge of the lathe EL and the milling machine VM as shown in FIG. 11, if the load of the lathe EL is higher than that of the milling machine VM, the load of the worker A on the lathe EL of the worker B is larger than that of the worker B. Shift to the load of the lathe EL to equalize the processing load.

Further, as shown in FIG. 12, when the load on the milling machine VM by the worker B is large, this load is transferred to the worker A to equalize the machining load. Data output section 9
Uses the processing load data for each equipment / worker assigned to the processing time frame, which is the frame of the processing capacity for each equipment / worker.
The schedule data Q1 and the processing equipment / worker load data Q2 are output and displayed on the data display device.

Of these, the schedule data Q1 is the machining load data assigned in time series according to the machining order of the parts in units, and the machining facility / worker load data Q2.
Is the processing load data for the same equipment / worker of a plurality of parts allocated to each processing equipment / worker.

That is, FIG. 14 shows a small schedule scheduling table (unit of parts). This small schedule scheduling table can be displayed and output for each processing facility and worker. In addition, in the figure, selection indicates all properties to be processed in the work group, and display classification indicates each component. The uniform number is the serial number of the product, the model is the model of the product, the order code is the drawing number, the product name is the name of the part, the number is the number of parts, and the routine is the machining process (machine process, sheet metal / welding, pressing, plating), The man-hours are processing man-hours (including the number of parts and setup change man-hours), the flag distinguishes between emergency products and outsourced products, and the parts machining period is displayed in the columns of October and November, for example.

FIG. 15 shows a load graph (January) using the processing equipment / worker load data. The processing equipment / worker load data can be displayed and output as one day's worth. In the figure, m is a capacity frame and n is a load graph.

After the execution of the scheduling, the rescheduling unit 10 performs the actual machining work according to the planned machining start date and the planned machining end date in the schedule data Q1. If the actual processing end date is entered and the actual processing start date is not entered even if the scheduled start processing date has passed, or if the actual processing end date has not been entered even after the expected processing end date has passed, the Judging that some parts are late,
The component is assigned the highest priority, and the component is reassigned, that is, rescheduling is performed.

When there are a plurality of parts whose machining start and machining end dates have passed, the rescheduling unit 10 allocates the parts with the earliest delivery date in order. Further, the rescheduling unit 10 displays a warning on the data display device of the terminal for each part of which the delivery date is exceeded.

As described above, in the above-mentioned one embodiment,
Parts allocation priority order data D1 and parts processing load data D
3 、 Processing capability adjustment priority data D6, processing equipment / worker capability data D4, etc. are input, multiple parts are arranged according to the parts allocation priority order and grouping classification, and the processing load is calculated from the first part in that order, and the parts delivery date. Or, it is allocated at the specified allocation interval according to the start date, and as a result, schedule data Q1 and processing equipment / worker load data Q
Since the scheduling engine 1 that outputs 2 is provided, high-speed, high-accuracy, highly flexible load leveling that prevents plan collapse can be performed, re-scheduling can be automated, and flexible processing capacity that corresponds to flextime can be set.

In this way, the schedule data Q1 and the processing equipment / worker load data Q2 are simultaneously displayed and output, so that the delivery deadline can be immediately answered to the customer, for example.

The specific effects will be described below. (1) It is possible to prevent the production plan from collapsing due to an urgent item, a component out-of-sync, or the like. (2) It is possible to automate load leveling manually by assigning parts to processing equipment and setting the priority order such as processing capacity adjustment when the production load is over into a system (apparatus).

For example, average processed parts per month, 10,000 points,
Average processing equipment per part ・ A scale of 4 units requires a scheduling (calculation only) time of about 10 minutes. As a result, human-system scheduling (all operations), which currently requires, for example, about 4 to 5 people x 8 hours / week, including about 1 person x 2 hours / week, including data preparation and confirmation. Scheduling becomes possible. (3) It becomes possible to apply it more effectively to the processing shop (on-site) by enabling the scheduling with the condition of having many operators. (4) By selecting the allocation interval of the parts processing load to the operator / equipment, multiple processing lead times can be set at the same time according to the degree of urgency, and it can be applied more effectively to the field. That is, the part allocation interval data D is used as a measure for emergency products.
5, for example, 1/1 day: One day is set as 8 hours and is assigned once every 8 hours. By shortening the set interval, the processing lead time can be shortened. (5) Within the allocation interval based on the component allocation interval data D5, there is no restriction on the processing order of the parts, so that the modified allocation of individual parts can be performed independently in a short time independently of other parts. This is very effective as a measure to adjust the collapse of the plan, which is a bottleneck.

Since the intervals for allocating the parts to the respective equipments / people are ruled in this way, it is possible to eliminate the parts interference between the processes making use of the advantages of the batch processing and to carry out the minimum necessary processing by the modularization processing. As a result, it is possible to simultaneously implement emergency processing measures, lead time reduction processing measures, improvement of operating rate, and reduction of processing time. (6) By making the allocation interval based on the parts allocation interval data D5 the same as the interval at which parts can be transported on site, it is possible to guarantee a certain amount of parts to be flowed and prevent plan collapse. (7) By setting flexible processing capacity (time zone) corresponding to flextime, it is possible to respond to “time saving” shops that employ flextime, which is expected to increase in the future. (8) In addition, as a method of capacity adjustment, by leveling work groups (to other work groups), expanding capacity quotas (overtime), leveling periods (delaying delivery dates), and by using alternative equipment / outsourced equipment , It is possible to give an immediate answer to the customer's delivery time, which is directly related to the manufacturing load, and to level the load for variable and variable production.

That is, it is possible to automate the flexible capacity adjustment adopting the rule for the production load, that is, to grasp and adjust the neck product / part / equipment in a short time. further,
The leveling accuracy of production load can be increased.

In addition, necessary information for each department, such as man-hours and progress, can be viewed and adjusted to manage and adjust the right person in the right place. The present invention is not limited to the above-mentioned one embodiment, and may be modified as follows.

For example, when a plurality of objects, slips, drawings, circulations, instruction information (computers) and people pass through different processes with different lead times and with many priority conditions and processing capacity adjustment conditions, Enables highly efficient scheduling under flextime. For example, scheduling of production process other than machining (inspection), inspection process, scheduling of design process (instruction, drawing), scheduling of logistics department (product), scheduling of clerical process department (slip), appointment medical treatment for patients Scheduling of scheduling (person) and circulation / instruction information (computer information).
