Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a scheduling / arranging management system for managing the scheduling and arrangement of various products. This is a manufacturing factory for products that are difficult, expensive, and made up of fairly complex parts configurations. Setting and specifying the ordering and delivery times for purchased parts of the product, and the schedule of work process units for various products in the factory The present invention relates to technology that is effective when applied to a schedule planning / arrangement management system used in the work of creating and modifying a plan.

[0002]

2. Description of the Related Art In the conventional business of managing schedule planning and ordering, generally, a parts list showing parts arrangements for parts arrangement for each model is created by design, and the schedule planning is performed based on the parts list of this design. The manufacturing side separately creates a bill of materials including the shop configuration of the work process, registers the lead time of each work process unit in the manufacture bill of materials, and uses the information of the manufacture bill of material to determine the item configuration (PN) and work process. Parts configuration including shop configuration (P
S) is created and registered on a computer.

[0003] Therefore, when creating a component configuration, a lead time for schedule development is registered for each component and each work process, and each product has an overall manufacturing lead time.

[0004]

Conventionally, as a master of schedule planning and ordering for each model, there is a configuration master in which both the ordered component configuration and the work configuration are combined in one bill of material finally produced by manufacturing. (However, the configuration master is composed of the component configuration and the item configuration), and the schedule planning and arrangement are performed using the item configuration and the component configuration.

[0005] In this case, however, there is a problem that it takes a long time to register the work process and the lead time in the parts table created by the design before the registration to the computer.

[0006] In addition, the conventional schedule planning is performed in a part configuration for each product model, but the component configuration is hierarchically deep and detailed like a work process unit. , When the delivery date is changed by the customer and the delivery time is short, etc.
It takes time to consider which work process lead time should be changed, and it takes time to change and correct the schedule.

An object of the present invention is to solve the above-mentioned problems and to provide a technique capable of easily creating, modifying and changing a schedule.

Another object of the present invention is to provide a technique capable of reducing the processing time of MRP expansion.

[0009]

SUMMARY OF THE INVENTION The present invention relates to a schedule planning / arrangement management system for managing a schedule for manufacturing a product and arranging a purchased product and an outsourced processed product. From the component configuration master showing the configuration and the shop configuration master showing the configuration of each work process that manufactures the product, create a model-specific schedule deployment master that shows the lead time aggregated for each work process, The necessary delivery date of the subunit is determined, the schedule of each component in each subunit is developed, the order date of each component is determined, and the ordering process is performed.

Conventionally, as a master of schedule planning and arrangement, 1
It has as one configuration master, and schedules and arrangements are made using its item configuration and component configuration. In this case, since the item indicating the component configuration for the schedule planning is formed hierarchically and deeply as described above, it takes time to change and correct the schedule.

Therefore, in the present invention, a schedule for each type of work, which is a master for schedule development for each work place, which is tabulated for each work process, is provided, and the schedule plan is modified with a somewhat large schedule for master for each model. To

In the master registration processing unit of the present invention, a material requirement plan (MRP: Material Requirements)
As a component configuration master for arranging and procurement of deployment of nts (planning), a product name, an item code, a quantity, and a lead time of the entire subunit, which indicate a component configuration at each level of the subunit, and an association between the subunit and the work process are shown. By registering in advance the shop code necessary for the execution, each subunit is configured to be associated with a certain serial number using the shop code.

[0013] Here, the MRP performs a development calculation for each product, consolidates the required amount for each part and raw material, and determines the types and quantities of parts and raw materials necessary for manufacturing a certain product such as inventory allocation and ordering. Refers to the process of calculating.

Next, the master registration processing section classifies the factory into work units, for example, work processes such as inspection, assembly, parts assembly and machining, as a shop configuration master for schedule development, and classifies each work process at a level. An association structure is established, and a shop code for associating each work process with a subunit is registered.

Next, when a schedule planning process is performed by the schedule planning processing unit, a shop configuration master for schedule development and a component configuration master of a subunit are linked in advance and the lead time for each work process is determined for each product model. And register it as a model-specific schedule development master.

Further, in the schedule planning process of the build-to-order manufacturing, a shop configuration master for schedule development is created each time, the subunit is associated with the component configuration master each time, and the lead time is totaled for each work process, and the order model is obtained. Register the unit-specific schedule development master for each unit.

Note that the lead time of each work process of the model-specific schedule development master is created by summing up the lead times of the component configuration master at the time of association between the component configuration master and the shop configuration master.

Next, the arranging processing unit determines the required delivery date of each subunit from the lead time of each work process of the model-specific schedule development master, and performs MRP development of the component configuration master for each subunit. The order date and delivery date of each part are determined so that the parts constituting the subunit are delivered by the required delivery date.

The schedule change processing unit changes the schedule by changing the lead time of the model-specific schedule development master at the time of the normally occurring schedule change, and only when the subunit itself is changed at the time of design change or the like. Change shop configuration master.

As described above, according to the present invention, the detailed lead time contents for each work process are held as a model-specific schedule development master, and when it is necessary to create a schedule or to modify or change the schedule, usually, Since the lead time of each work process in the model-specific schedule development master is used, there is an advantage that the schedule plan can be easily modified and changed.

Further, since the MRP development can be performed only by the component configuration master in units of subunits, the processing time of the MRP development is reduced. In addition, when work is performed in a work process that is not included in the parts list of the design, there is a merit that it can be easily handled by changing and adding only the shop configuration master of schedule development.

As described above, according to the schedule planning / arrangement management system of the present invention, a schedule is created by using the lead time totalized for each work process in the model-specific schedule development master and the component configuration master for each subunit. , Corrections and changes, it is possible to easily create, correct and change the schedule.
