Abstract

A production/purchase management processing system is provided which includes a master production schedule which describes a production planning of each of a plurality of kinds of products independently for each period. A product construction/item master is provided in the system for describing information related to parts which form the product for each of the products. A stock/remaining order information source of the system describes stock quantity and remaining orders for the items which represent the product or the part. A production planning processor reads the contents of the master production schedule, the product construction/item master and the stock/remaining order information source and outputs a purchase planning order and a production planning order which are generated based on the read contents. The system further includes a reorganization processor which outputs a reorganization production planning order for at least one item which is included in the production planning order based on processes carried out in the production planning processor and the reorganization processor.

Claims

1. A production/purchase management processing system comprising:

a master production schedule which describes a production planning of each of a plurality of kinds of products independently for each period;

a product construction/item master which describes information related to parts which form the product for each of the products;

a stock/remaining order information source which describes stock quantity and remaining orders for items, said items respectively representing the product or the part;

a production planning processor for reading the contents of said master production schedule, said product construction/item master and said stock/remaining order information source, and for outputting a purchase planning order and a production planning order which are generated based on the read contents, said purchase planning order satisfying a required number of an arbitrary item by purchase, said production planning order satisfying a required number of an arbitrary item by production; and

a reorganization processor for outputting a reorganization production planning order for each of the products having as a constituent element thereof an item for which the production planning order is output from said production planning processor, wherein said reorganization production planning order is output for at least on item which is included in the production planning order based on processes carried out in said production planning processor and said reorganization processor.

2. The production/purchase management processing system as claimed in claim 1, wherein said reorganization processor generates a processing planning order which includes at least an item number of a concerned item, a delivery time, a production number and additional information received from said product construction/item master, said additional information including at least an arrangement classification which instructs whether or not the reorganization production planning order is to be output, said reorganization processor carrying out the process with respect to those items for which the arrangement classification is given and generating the reorganization production planning order based on the processing planning order.

3. The production/purchase management processing system as claimed in claim 2, wherein said processing planning order further includes an order number which is uniquely assigned in one-to-one correspondence with the item number and a starting time.

4. The production/purchase management processing system as claimed in claim 1, wherein said reorganization processor generates a processing planning order which includes at least an item number of a concerned item, a delivery time, a production number and additional information received from said product construction/item master, said additional information including at least a low level code which indicates a lowest level associated with a concerned item in a hierarchical structure of the product which is formed by parts in one or a plurality of levels of the hierarchical structure and an arrangement classification which instructs whether or not the reorganization production planning order is to be output, said reorganization processor carrying out the process with respect to those items for which the arrangement classification is given in a sequence starting from the item in a highest level of the hierarchical structure and generating the reorganization production planning order based on the processing planning order.

5. The production/purchase management processing system as claimed in claim 4, wherein said processing planning order further includes an order number which is uniquely assigned in one-to-one correspondence with the item number and a starting time.

6. The production/purchase management processing system as claimed in claim 1, wherein said reorganization processor generates a processing planning order which includes at least additional information received form said product construction/item master, said additional information including at least a low level code which indicates a lowest level associated with a concerned item in a hierarchical structure of the product which is formed by parts in one or a plurality of levels of the hierarchical structure, said reorganization processor carrying out the process with respect to those items in a sequence starting from the item in a highest level of the hierarchical structure and generating the reorganization production planning order based on the processing planning order.

7. A production/purchase management processing method comprising the steps of:

(a) reading the contents of a master production schedule, a product construction/item master and a stock/remaining order information source so as to generate a purchase planning order and a production planning order based on the read contents, said master production schedule describing a production planning of each of a plurality of kinds of products independently for each period, said product construction/item master describing information related to parts which form the product for each of the products, said stock/remaining order information source describing stock quantity and remaining orders for items, said items respectively representing the product or the part, said purchase planning order satisfying a required number of an arbitrary item by purchase, said production planning order satisfying a required number of an arbitrary item by production; and

(b) generating a reorganization production planning order for each of the products having as a constituent element thereof an item for which the production planning order is generated,

said reorganization production planning order being generated for at least one item which is included in the production planning order based on processes carried out in said steps (a) and (b).

8. The production/purchase management processing method as claimed in claim 7, wherein said step (b) generates a processing planning order which includes at least an item number of a concerned item, a delivery time, a production number and additional information read from said product construction/item master, said additional information including at least an arrangement classification which instructs whether or not the reorganization production planning order is to be generated, said step (b) carrying out the process with respect to those items for which the arrangement classification is given and generating the reorganization production planning order based on the processing planning order.

9. The production/purchase management processing method as claimed in claim 8, wherein said processing planning order further includes an order number which is uniquely assigned in one-to-one correspondence with the item number and a starting time.

10. The production/purchase management processing method as claimed in claim 7, wherein said step (b) generates a processing planning order which includes at least an item number of a concerned item, a delivery time, a production number and additional information read from said product construction/item master, said additional information including at least a low level code which indicates a lowest level associated with a concerned item in a hierarchical structure of the product which is form ed by parts in one or a plurality of levels of the hierarchical structure and an arrangement classification which instructs whether or not the reorganization production planning order is to be generated, said step (b) carrying out the process with respect to those items for which the arrangement classification is given in a sequence starting from the item in a highest level of the hierarchical structure and generating the reorganization production planning order based on the processing planning order.

11. The production/purchase management processing method as claimed in claim 10, wherein said processing planning order further includes an order number which is uniquely assigned in one-to-one correspondence with the item number and a starting time.

12. The production/purchase management processing method as claimed in claim 7, wherein said step (b) generates a planning order which includes at least additional information read from said product construction/item master, said additional information including at least a low lever code which indicates a lowest level associated with a concerned item in a hierarchical structure of the product which is formed by parts in one or a plurality of levels of the hierarchical structure, said step (b) carrying out the process with respect to the items in a sequence starting from the item in a highest level of the hierarchical structure and generating the reorganization production planning order based on the processing planning order.
