Optymalizacja planowania wykonawczego przezbrajalnych linii produkcyjnych w zintegrowanym systemie zarządzania klasy MRP II

It is common opinion that MRP II production control systems are good for manufacturing of discrete type whereas the Just-In-Time method is better for repetitive production. This opinion is based on many qualitative analyses but direct quantitative comparison of their performances, based on simulation of both production control systems applied to the same complex process, is not possible because their decision variables are different. To enable comparison of MRP II with JIT an extension of MRP II system is necessary. An executive planning algorithm is needed to process work orders from MRP II system to execution orders with the same formal Structure as orders coming from JIT system have. It should be an optimal algorithm to be certain that it does not deteriorate MRP II decisions. The paper shows an optimization model of the problem for a repetitive production process in a complex manufacturing system which is composed of production lines. The total cost of setups and inventory holding is minimized.
