摘要: This paper is devoted to the calculation of stability radius an optimal schedule for a general shop scheduling problem, where objective minimize mean flow time. The denotes largest quantity independent variations processing times operations such that problem remains optimal. We derive formulas calculating radius, and necessary sufficient conditions when it equal zero. Moreover, computational results on randomly generated job problems are discussed.
