Table 3 below shows an example of information on whether or not the tank and the drum filling machine can be connected and the amount of the end cutting oil.

In the table, Edge indicates the amount of cut oil (unit: L). M1 indicates a No. 1 drum filling machine. M2 indicates a No. 2 drum filling machine. M3 indicates a No. 3 drum filling machine. M4 indicates a No. 4 drum filling machine. M5 indicates a No. 5 drum filling machine. M6 indicates a No. 6 drum filling machine. M7 indicates a No. 7 drum filling machine. M8 indicates a No. 8 drum filling machine. “0” indicates that connection is not possible, and “1” indicates that connection is possible.

  The end cutting information DB 43 is a database that stores information relating to the amount of end cutting oil (end cutting amount). The amount of end cutting oil is the amount of non-standard lubricating oil that is discharged in the end cutting operation and is not shipped as a product. For example, as shown in Table 3 above, it is stored in association with a product tank.

Table 4 below shows an example of information on the relationship between the lubricating oil (FILLING_OIL) and the front oil (BEFORE_OIL) filled as a product, and the amount (unit: L) of the end cutting oil (EDGE_LIMIT). The types of the lubricating oil and the front oil are indicated by codes (001, 002,...). The pre-oil is a lubricating oil processed immediately before changing the oil type.

The product information DB 44 is a database that stores information related to products (brands, varieties), and includes product ID, (product) oil type, inspection time, filling time, cleaning time, amount of cleaning fluid used (flow rate of cleaning oil) X information on the cleaning time) is stored. The product information DB 44 is a data database that stores information related to product groupings (lubricating oil groups).
The cleaning time and the amount of cleaning fluid used are set so that the product test of the product to be filled after the end cutting operation passes. Here, as a unique problem when filling a product of lubricating oil, when a product different from the target product is mixed (contaminated) with the target product, the characteristics and stability of the target product may change. Can be mentioned. Therefore, for each combination of the target product and the different product, an acceptable range of the mixing amount for passing the product test of the target product is found, for example, the order of products to be filled (product type in advance) It is preferable to obtain the minimum required amount of cleaning fluid used for each product combination before and after switching, and store it in the product information DB 44 as product information. As an example, if the same type of product is continuously processed, the amount of cleaning fluid used can be greatly reduced. Therefore, the amount of cleaning fluid used is reduced by determining the order of products to be processed in consideration of the data related to the lubricant group and products.

Table 5 below shows an example of information related to the lubricant group.

The break time DB 45 is a database that stores information related to a break time during which a worker does not execute a work item, and stores data related to a break start time and a break end time.
Table 6 below shows an example of information related to the break time.

  The labor cost DB 46 is a database that stores information on labor costs.

  The parameter DB 47 is a database that stores information on SA parameters. The SA parameter uses an annealing method for optimization calculation and adjusts the priority used for the calculation. In the annealing method, transition probabilities corresponding to the goodness of the solution are set for each solution in the neighborhood (the better solution is more likely to be transferred), and the next solution is randomly selected according to the probability. The transition probability is adjusted by a parameter called temperature. (Reference: "Numerical calculation" by Ichiro Kawakami, Iwanami Shoten 1989)

Table 7 below shows an example of information related to the SA parameter.

  The optimization information DB 48 is a database that stores information related to work plan optimization. The information regarding the optimization of the work plan includes a program for creating a work plan that satisfies the following optimization items.

Table 8 below shows an example of information on optimization items. Minimizing the number of workers means that the number of people operating the filling machine can be reduced by using only the minimum required filling machine. Further, to eliminate the useless waiting time in consideration of the product test passing time means to eliminate the waiting time due to the waiting for the test result (the time when there is nothing that can be worked on).

  The electronic control unit 20 creates a work plan based on information on the constraint conditions by executing the program stored in the storage unit 23. The electronic control unit 20 includes a calculation unit 21 that creates a work plan.

  The calculation unit 21 determines the order of products to be filled and the execution time of work items when filling each type of product, and creates a work plan for one day. FIG. 2 is a diagram illustrating an example of a work plan created by the filling plan creation support device.

  The calculation unit 21 creates a work plan including a break time in which the work item is not performed in consideration of the information regarding the break time stored in the break time DB 45. In FIG. 2, the break time is indicated as “B”.

  The computing unit 21 creates a work plan in consideration of information on worker assignment and information on overtime. The calculation unit 21 creates a work plan so that one worker is responsible for a plurality of filling machines 3 of the same type. In addition, when overtime occurs, the calculation unit 21 creates a work plan so that the work is concentrated on a specific worker so that fewer workers work overtime. Moreover, the calculating part 21 can aim at the optimization of the whole filling operation by comparing the overtime fee and the loss cost of the cleaning fluid.

  The computing unit 21 determines the filling order for each type of container in the filling operation based on the information related to the priority of the filling order according to the packing form. For example, the priority of the filling order is set higher for a container having a smaller capacity than a container having a larger capacity. The calculation unit 21 creates a work plan so that the container with the smallest capacity is not set as the container to be filled last.

  The computing unit 21 determines the order of the lubricating oil products to be filled so that the amount of cleaning oil used and the amount of end cutting oil discharged are minimized. And the start time of the work item corresponding to every product of lubricating oil is determined, and a work plan is created. The calculation unit 21 may create a work plan based on the information stored in the storage unit 23 so as to minimize the amount of cleaning oil and end cutting oil, and the device information stored in the storage unit 23 is stored. The cleaning oil amount and the end cutting oil amount may be calculated based on the information related to the pipe length.

  The calculation unit 21 allocates a series of work items so that a plurality of (for example, two to three) filling machines are assigned to the same worker, and creates the same work plan for the plurality of filling machines 3. For example, in FIG. 3, the same work plan is set for the No1 drum filling machine and the No2 drum filling machine. Similarly, the same work plan is set for the No. 4 drum filling machine and the No. 5 drum filling machine, and the same work plan is set for the No. 6 to No. 8 drum filling machines.

  The computing unit 21 performs recalculation based on the created work plan, and creates a new work plan in consideration of the optimization items shown in Table 8 above.

  The electronic control unit 20 includes a data update unit 22 that updates information stored in the storage unit 23 (information on constraint conditions). The filling plan creation support apparatus 10 can input new data from the input unit 11 and rewrite old data with new data.

  As described above, the filling plan creation support apparatus 10 according to the present embodiment includes a plan creation unit that supports creation of a work plan in the filling facility 2 capable of filling a variety of products into each container. The unit 21 can determine the order of products to be filled and the execution time of work items when filling each type of product as a daily work plan. In creating the daily work plan, the calculation unit 21 of the plan creation unit considers the information regarding the packing state of the container, the information regarding the filling request of the day, and the facility information regarding the filling facility 2 as a constraint condition. A work plan can be created. This determines the order of products to be filled so that the amount of cleaning fluid is reduced. In addition, since the execution time of the basic work items cleaning work, cutting work, and filling work are determined so that the work by the workers is made more efficient, the portion depending on the planner is reduced, Reasonable efficiency can be achieved.

(Experimental result)
In this example, the filling plan creation support device 10 according to the embodiment of the present invention is applied to the filling equipment of a lubricating oil production plant in the case of 10 filling machines and 500 types of total production items (brands). An experiment was conducted to evaluate the validity. The creation of a work plan using the filling plan creation support apparatus 10 was compared with the creation of a conventional manual work plan. As a result, in the work plan created by the filling plan creation support device 10, it is possible to plan the optimal filling machine allocation, and when the conventional standard cleaning oil usage is 100%, the usage is reduced to 85%. We were able to. The calculation time required to create the work plan was about 1 minute using a Pentium (product name) 1 GHz computer. Assuming that the planned time based on the conventional standard is 100%, the work time of 5% can be planned, and the work time of the plan creator can be greatly reduced.

  As mentioned above, although this invention was concretely demonstrated based on the embodiment, this invention is not limited to the said embodiment. In the above-described embodiment, the filling plan creation support apparatus is applied to create a work plan in a filling facility for filling lubricating oil, but may be used to create work plans for other filling apparatuses. For example, the filling plan creation support apparatus of the present invention may be applied to plan creation in a filling facility that fills containers with other beverages, medicines, and the like as a variety of products.
