TL;DR

Mixed‑model assembly lines produce diverse products without large inventories, and effective operation requires scheduling that maintains a constant part usage rate, a goal known as levelling or balancing in JIT systems. This paper seeks to establish a theoretical foundation for scheduling such JIT mixed‑model lines. It introduces new scheduling algorithms and heuristics derived from that theory.

Abstract

Mixed-model assembly lines are used to produce many different products without carrying large inventories. The effective utilization of these lines requires that a schedule for assembling the different products be determined. For Just-In-Time (JIT) production systems, which require producing only the necessary products in the necessary quantities at the necessary times, the objective is to keep a constant rate of usage of all parts used by the line. This is called levelling or balancing the schedule. This paper develops a theoretical basis for scheduling these systems, and presents new scheduling algorithms and heuristics.
