7. SALPS for Stochastic Assembly Line

Numerous studies based on a deterministic or stochastic approach have examined ALSs. However, no stochastic models have yet been found that are able to deal with the simultaneous determination of cycle time and buffers. We have already presented a two stage design method for the simultaneous determination using an SCA. This chapter therefore develops SALPS for the stopper/no-stopper type using the two-stage design method. SALPS consists of (area) line balancing, buffer design (items/time), and a pair strategy map. This Matsui–Yamada method can adjust strategically to follow demand changes according to the pair strategy map consisting of cycle times (input) and the number of stations (output). A numerical example for SALPS performance is given and the ellipse theory in the pair strategy map is discussed.
