Abstract: This paper studies a bicriteria scheduling problem on a parallel-batching machine to minimizemaximum cost andmakespan simultaneously. Each job has two components: standard component and specific component. Standard components are processed in batches. Specific components are processed individually. The processing order of two components of a job has no constraint. A job is completed only when its two components are completed. For the simultaneous optimization scheduling problem, we design an O(n4)-time algorithm.

Key words: Bicriteria scheduling, Two-component, Makespan, Maximum cost, Pareto optimal schedules
