Abstract

A bicriterion objective for levelling the schedule of a mixed-model, Just-In-Time assembly process is examined. The two objectives considered are: minimizing the sum of deviations from a perfectly level schedule (min-sum), and minimizing the maximum deviation (min-max). This bicriterion approach combines the desirable properties of both criteria. It is shown that several Pareto optimal solutions may be efficiently determined. Furthermore, the in-core storage required to solve the bicriterion objective subject to a constraint on the maximum deviation is shown to be significantly lower than the storage required for the 'standard' min-sum problem, because there are fewer edges in the associated graph.
