The problem of maximizing the weighted number of on-time jobs on a single machine with time windows (STW) is shown to be strongly NP-hard. An efficient. heuristic is presented for STW. Computational experiments indicate that the performance of the heuristic is quite good.

We study the problem of minimizing the weighted number of late jobs to be scheduled on a single machine when processing times are equal. In this paper, we show that this problem, as well as its preemptive variant, are strongly polynomial. When preemption is not allowed ( 1"p H "p, r H " w H ; H ), t
