Line Balancing-Sequencing for Mixed-Model Assembly

TLDR

Mixed‑model assembly occurs when multiple models of the same product are intermingled on a single line, and the varying work requirements per model create uneven flow. This paper aims to adapt single‑model line‑balancing techniques to mixed‑model schedules. It introduces a sequencing procedure that determines the order in which models flow down the line. The resulting line‑balancing and sequencing procedures, which account for many factors, are applicable to a wide range of assembly lines.

Abstract

Mixed-model assembly occurs when more than one model of the same general product are intermixed on one assembly line. The amount of work required to assemble units can vary from model to model, creating an uneven flow of work along the line. This paper describes a procedure of adapting single-model line balancing techniques to mixed-model schedules. The paper also introduces a sequencing procedure for determining the order in which models are to flow down the line. Because the line balancing and sequencing procedures consider a wide variety of factors, they are applicable to many types of assembly lines.
