摘要
Maximizing the total weight of just-in-time jobs under multi-slot conditions was proven recently to be NP hard. We consider a heuristic algorithm for this problem. First, we compute a schedule that minimizes the number of time slots. Next, we make a new set of jobs by merging existing jobs in the schedule. Then, we compute a minimum cost flow for the network constructed from this new set of jobs. Finally, we obtain a feasible schedule from the flow. Moreover, we implement the heuristic algorithm, and consider its features and performance from the computational experimentation.
