This paper investigates the coordinated scheduling problem of production and transportation in a two-stage supply chain, where the actual job processing time is a linear function of its starting time. During the production stage the jobs are first processed in serial batches on a bounded serial...

In this paper, we address the problem of parallel batching of jobs on identical machines to minimize makespan. The problem is motivated from the washing step of hospital sterilization services where jobs have different sizes, different release dates and equal processing times. Machines can...

We study a scheduling problem with rejection on a single serial batching machine, where the objectives are to minimize the total completion time and the total rejection cost. We consider four different problem variations. The first is to minimize the sum of the two objectives. The second and the...
