Two-Agent Single Machine Scheduling with Deteriorating Jobs and Rejection

We consider two two-agent scheduling problems with deteriorating jobs and rejection. Two agents A and B compete for the usage of a single machine. The actual processing time of job JjX is pjX=bjXa+bt, X∈A,B, where bjX is the normal processing time of JjX, a≥0, b≥0 and t denotes the starting time of...

Zusammenfassung:We consider two two-agent scheduling problems with deteriorating jobs and rejection. Two agents A and B compete for the usage of a single machine. The actual processing time of job JjX is pjX=bjXa+bt, X∈A,B, where bjX is the normal processing time of JjX, a≥0, b≥0 and t denotes the starting time of JjX. A job is either rejected by paying a rejection penalty, or accepted and processed on the machine. The objective is to minimize the sum of the completion time of the accepted A-jobs and total rejection penalty of the rejected A-jobs subject to an upper bound on the sum of the given objective function fB of the accepted B-jobs and total rejection penalty of the rejected B-jobs, where fB∈CmaxB,∑CjB. We give dynamic programming algorithms for them, respectively. When fB=CmaxB, we present a fully polynomial-time approximation scheme (FPTAS) for the case a=0 and b=1. When fB=∑CjB, a fully polynomial-time approximation scheme is also presented.
