摘要:
Embodiments of the present invention provide a production planning method and system. Where a manufacturing apparatus is shared by a plurality of products in a production line, if a manufacturing (production) availability number is changed, a cause parameter is automatically investigated so that a production plan with high precision can be prepared in a short time. With respect to a production plan as the previous/current comparison objects, a production process used in the production plan in which a change occurs, is extracted. From the production process, a parameter item to be used in the production capacity evaluation is extracted for all products, a difference comparison is made between the value of the previous parameter and the value of the current parameter, so that the parameter item as the cause is specified. The combination of the cause parameter items is calculated, and a cause parameter list is prepared. Next, from the specified parameter list, the parameter item is sequentially changed, and the manufacturing (production) availability number is recalculated. An influence index given to the manufacturing (production) unavailability number by the cause parameter, is calculated.
摘要:
A system and method for generating disassembly, procurement and production plans dealing with recyclable parts and products are provided. Production demand information on products to be manufactured, collection schedule information on individual used products and recyclable part table on recyclable parts contained in the used products are stored in memory; recyclable part availability information is generated by referring to the collection schedule information and the recyclable part table; and by referring to the production demand information and the recyclable part availability information, a disassembly plan on the recyclable parts is created based on the production demand. Further, the production demand information and the recyclable part availability information are referenced to generate a procurement plan on parts and materials that cannot be fully supplied from available, recyclable parts alone. Based on the disassembly and procurement plans, a production plan is created.
