Abstract

In many realistic production environments, jobs will take longer time if they begin later. This phenomenon is known as deteriorating jobs which have widely been studied. In this paper, the piecewise linear deterioration is discussed in a single machine scheduling problem of minimizing the maximum tardiness. After proving the NP-hardness of problem, a Branch and Bound and a heuristic algorithm with O(n2) are proposed for solving the large scale problems to near optimal solutions. The heuristic approach is also used to determine an upper bound on the solution of B&B algorithm. The computational results for evaluating performance of the two algorithms confirm the excellent performance of B&B algorithm as it is able to solve the problems with at least 32 jobs within a reasonable time. Notably, the heuristic approach is quite accurate and efficient with an average error percentage of less than 0.3%.
