摘要:
The production of semiconductor devices manufactured through a plurality of manufacturing sites is unitarily managed and an appropriate production plan is instructed. A computer projects a production plan of an entire company based on various information. The production plan is provided to each manufacturing site as a production instruction and provided to each business person or customer as a storing reply or an order accepting period reply. If the projected production plan (possible production volume) does not coincide with a production plan (necessary production volume), parameters obtained by correcting production allocation, production capability, lead time, yield and the like are re-input from a parameter input terminal. Based on the corrected parameters, the computer re-projects the production plan and projects an optimum production plan.

A seat according to this invention comprises a seat part and a backrest attached to a rear side of the seat part. The seat part comprises a cushion attached to a pair of side supporting frame members connected with each other. The backrest comprises a cushion attached to an inverse U shaped back frame. Each end of the inverse U shaped back frame is connected to each rear end of the side supporting frame members of the seat part. The inverse U shaped back frame comprises side supporting parts that are positioned in parallel and a top supporting part that connects top ends of the side supporting parts. Lower ends of side supporting parts are connected to rear ends of the side supporting frame members of the seat part via lower attaching parts, respectively. Each lower attaching part has an ear part that projects frontward. Supporting members connect between the side supporting parts and the ear parts of the lower attaching parts, respectively. According to this invention, a rearward tilting of its backrest can be restrained and absorb impact energy when a rear impact acts on the seat.
