Abstract

This paper presents a logistic algorithm that improves traffic conditions in a network-like automated material handling system (AMHS). The algorithm uses a lookahead procedure and series of nodal parameters in order to balance the flow of traffic to and from load/unload nodes. In doing so, it helps manage, distribute and allocate free AMHS vehicles more efficiently. A simulation model of the algorithm, material control system and the AMHS was developed and tested on various types of semiconductor manufacturing facility layouts. The results of the simulated algorithm demonstrate up to 30% improvement in the AMHS lot delivery time
