Double speed single production line
This paper presents a hybrid push and pull production management approach called double speed single production line (DSSPL), developed for industries that produce a large variety of slightly different items subject to highly variable demand. Because of this framework, only mediocre lead times for all their products can be guaranteed. The DSSPL system suggests improving their logistic performances by splitting products into A- and B-classes, according to a market oriented policy, then by producing, on a single line, but at different speeds, the A- (fast) and the B-products (slow), thus leading to a better allocation of production resources. A discrete event simulator has been developed in order to evaluate performances of the DSSPL approach to pure push and pull systems. First results are presented and the performance of the DSSPL system is discussed.
