We provide a new formulation and solution procedure to sequence a mixed model just-in-time (JIT) assembly system. Mixed model JIT assembly systems are a fundamental part of the well-known "Toyota Production System." The underlying idea in sequencing these systems is to maintain a constant usage...

Scheduling of multistage serial production systems under constant demand and infinite horizon is considered. The production stages operate with periodic shut-downs and startups. An integer nonlinear programming formulation is presented for determining a stationary, cyclic schedule with no...

This paper deals with mixed-model line balancing; i.e., the problem of combining line balancing with lot sizing in a multi-product environment. Recent developments in the area of multi-echelon production/inventory systems are applied, and algorithms are developed which determine the number of...

We study the problem of using information about the type of machine failures to control production. When each station in a two stage flowline has a single machine, the processing time distributions are Erlang, and the time to fail as well repair a machine are exponentially distributed; we show...
