Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an input planning support system, and more particularly to management of operations for determining an input product and an input quantity of a product manufactured by passing through a plurality of processes of a plurality of plants. Regarding the input planning support system to be performed.

[0002]

2. Description of the Related Art Conventionally, as shown in Japanese Patent Laid-Open No. 02-311250, a production plan has been established by determining a work order based on the in-process status of equipment in each process.

Further, conventionally, as shown in the business flow chart of FIG. 5, it is necessary to receive the input target product information 100, the frontmost factory input quota information 103, and the possessed material information 102 from the higher-level production plan creating system 500, which is necessary for production. Whether you have materials, whether there is any remaining in the factory's input slot, decide the input item while searching multiple ledgers, and you can select different products that require the same material in multiple plans. When making an input target, the input plan was created after grasping the original holding material information and the usage status of the material according to another plan.

[0004] In addition, in the conventional introduction plan of the product to be manufactured through a plurality of processes of a plurality of factories, the front-end factory has the materials necessary for production, and the input frame of the front-end factory and the next factory of the next factory. There is no idea of creating a loading plan for the frontmost factory so as not to exceed both the capacity of the equipment for each charging date at the same time. While investigating this, he was preparing the input plan for the frontmost factory.

[0005]

However, in the above-described conventional input plan preparation method that cannot grasp the plurality of judgment indexes in a unified manner, the time required for information retrieval and information collection increases, and it takes a lot of time to prepare the plan. In addition, if the information collection is omitted, there is a problem that the plan cannot be created based on accurate information and the reliability of the plan is deteriorated. There is also a problem in that the items to be considered when creating a plan may change, and it is not possible to maintain uniform planning.

[0006] Further, in consideration of only the items to be considered in the production planning of the product which is manufactured through the plural processes of the conventional plural factories described above, the process having the process facility capacity lower than the front process exists as the process after the front process. In this case, it becomes a neck process in which it is impossible to fully process the work-in-process that has flowed from the front-end process in the subsequent process, increasing the work-in-process between processes, which in turn increases the manufacturing lead time for all processes. There is a problem of doing.

An object of the present invention is to realize an efficient product flow through a plurality of factories in the production of a product manufactured through a plurality of processes at a plurality of factories, and information on a target product to be used in a business for preparing a plan for supply. By centrally managing the possessed material information and equipment capability information, the above information can be easily judged,
It is to provide an input plan creation support system that enables efficient input plan creation.

[0008]

According to the input plan creation support system of the present invention, there is an input target for which the planned process has not been input, based on the input target product information and the input reserved product information created by the higher-level production plan creation system. Check whether or not to do so, and if it exists, delete the first function from the input target, the factory input frame of multiple factories, the process in process of the frontmost factory, and the next factory input of the input target for which the planned process has not been input. Date, the load quantity of the work-in-process load target for the next factory load day, and the load quantity of the load target of the planned process that has not been input by the first function and is deleted from the load target information. It is necessary to sort the second function that calculates the equipment availability frame by the next factory launch day of the possible next factory and the loading target determined by the first function according to the priority key, and in the descending order of priority, by loading. Whether the number of materials to be used does not exceed the possessed number, whether the input number exceeds the factory input quota of the frontmost factory calculated by the second function, and the input number is calculated by the second function. Check to see if the number of equipment that can be put into the next factory at the next factory is exceeded.
If the above three items are satisfied, the third function that repeats the work to be input until the end of the priority, the target name of the input target, the input quantity, the necessary material possession number, and the factory of the front factory on the GUI The remaining number of input slots and the remaining number of input slots for equipment at the next factory by the next factory input date are displayed, and when the input volume of the input target is changed, the required number of required materials and the front The fourth function to change and re-display the remaining number of the factory input slots of the factory and the remaining number of the equipment inputable slots by the next factory input date of the next factory, and the target not included in the input target, the target of the target By inputting the name and the input quantity from the GUI, a fifth function of searching for other information necessary for the input target is included.

[0009]

The present invention will be described in detail with reference to the drawings.

It is composed of

FIG. 2 is an information correlation diagram showing an embodiment of the invention of claim 2.

As shown in FIG. 2, the production plan creation support system 50 which receives the input target product information 100 and the input reserved product information 101 created by the higher-level production plan creation system 500.
The item 1 compares the input reservation product information 101 and the input target product information 100 to search for a matching input target. If they match,
The input target is determined to be the input target for which the planned process has not been input, and is deleted from the input target.

FIG. 3 is a conceptual diagram of the invention of claim 3.

From the process capability information created by the higher-level production plan creating system 500, the daily factory input slot 11 of each factory is calculated.

Next, according to the process in-process information, from the position of the process in the front factory to which the process in-process is input and the remaining manufacturing period in the front factory, the date when the process is input to the front process of the next factory, Calculate the factory entry date 4.

Further, the number of the process-target input targets is added for each next factory input date, and the process-process load 30 for each next factory input date is piled up.

Next, with respect to the input target which has been deleted from the input target product information by the function of claim 2 and for which the planned process has not been input, the next factory input from the construction period at the frontmost factory and the input date to the frontmost process. Calculate day 4.

Further, the quantity of the planned process-uninjected input objects is added every day when the next factory is input, and the planned process-uninput load 40 for each next factory input date is piled up.

From the daily factory input frame 12 of the next factory in the daily factory input frame 11 of each factory, the process in-process load 30 according to the next factory input date and the next factory input date plan The rest of the completed process non-input load 40 and the rest are set as the facility input possible frame 7 for the next factory input date.

FIG. 4 is a processing flow chart showing an embodiment of the invention of claim 4.

The first step is to sort the input target product information 100 created by the higher-level production plan creation system in ascending order using the latest process availability date 20 calculated by back-calculating the manufacturing lead time from the delivery date as a priority key. And

It is checked that the number of required materials does not exceed the number of possessed items among the input objects having the highest priority among the input objects sorted in the first step, and if they exceed, the next priority order is determined. The process of setting the input target as the input candidate is the second step.

It is checked that the input quantity of the above-mentioned input candidates does not exceed the daily factory input slot 13 of the above-mentioned factory, of the daily factory input slots 11 of each factory. The process of returning to the second step is the third step.

It is checked that the input quantity of the input candidate does not exceed the facility input possible frame 7 for the next factory input date. If it does not exceed, the input plan is set, and if it exceeds the second step. The process of returning to is the fourth step.

When there are no more objects to be sorted that have been sorted according to the priority key, the second and third steps are performed again in the order of priority with respect to the objects to be input which have not been decided to be re-created, to create a projecting plan.

Next, as shown in FIG. 1, as a GUI,
Next factory name and product type name 1 in the next factory, input target name 2, front factory input date 3, previous factory input date 4, input target number 5, input decision number 6, and next factory input date The equipment available frame 7, the number of required materials held 8, the total number of input of the frontmost factory 9 and the factory input frame 10 of the frontmost factory are displayed.

When the number of inputs is determined for each input target name 2 and input is made in the input determination number input field 6, the factory input frame 10 of the forefront factory and the equipment input for each process by the next factory input date are accordingly input. The possible frame 7 and the required number of possessed materials 8 are changed and displayed again.

Further, if the target name and the number of targets that are not included in the input target name 2 on the GUI are entered, the
Change of the input target name 2, the addition of the target to the input target number 5, the factory input frame 10 of the frontmost factory, the facility inputable frame 7 by the next factory input date, and the necessary material possession number 8 Then redisplay.

The input plan 200 is created as described above.

[0031]

As described above, in the input plan creation support system of the present invention, the input target for which the planned process has not been input, which has already been reserved as the input plan but has not been input to the process, is changed from the input target. Each factory input frame that was deleted and calculated from the process in-process information and the process equipment information, and the load on the next factory input date of the process in-process input target and the planned process non-input input target that has already been input to the process Deleted from the factory input frame of the next factory of each factory input frame, calculate the next factory equipment inputable frame that can be actually input, sorted according to the input target item and the priority key, in the sorted priority order, Whether there is a required number of materials in the manufacturing of the input target,
By checking whether or not the capacity of the frontmost factory and the capacity of the next factory that can be used by the next factory for the next factory have been exceeded, it is planned to set the target of input that satisfies all requirements. In the production of products that are manufactured through multiple processes, by realizing an efficient product flow through multiple plants, it is possible to reduce work in process between processes and shorten the manufacturing lead time for all processes. , Again, GUI
