Abstract:

This paper considers two agent scheduling problems with fixed time windows on a single machine. The jobs of the first agent might be preemptive. There exists agreeable condition with release time and due data. The objective function is to minimize the total tardiness. The focus is to find an optimal sequence that minimizes the objective of the first agent, while keeping all jobs of the second agent schedule within fixed time windows. By block principle, we present a pseudo-polynomial time dynamic programming algorithm when fixed time window equals the processing time. If the fixed time windows is larger than the processing time, we give the time complexity of the proposed problem.

Key words: single scheduling, two-agent, total tardiness, fixed time windows
