<p>PURPOSE:To perform stable production by predicting work piece input turn causing jig shortage and wait for jig mounting/dismounting work thereby and changing the work input turn to another input turn not causing such shortage or wait thereby and by rearranging work pieces for other products so ae to keep the conditions of fixed production rate. CONSTITUTION:In a production line for various kinds of products wherein jigs and work pieces are mounted/dismounted at work stations in a fixed order, a work piece input order plan is made to fix the production rate of each product to the quantity given by each production plan. When work piece input turns causing jig shortage and wait for jig mounting/dismounting work thereby for this work piece input order plan is predicted, the turn is changed for work pieces of another turn not causing jig shortage thereby, or the input turn causing the wait for mounting/dis-mounting thereby and the input turn just before the turn causing the wait for mounting/dismounting work are interchanged with each other, and the turns of other products are rearranged not to break the conditions whereunder a production rate is fixed as far as possible. In such manner the occurrence of jig shortage and wait for operators are prevented, and a stable and efficient production line can be operated.</p> |
