This paper breaks new ground by modelling lot sizing and scheduling in a flexible flow line (FFL) simultaneously instead of separately. This problem, called the ‘General Lot sizing and Scheduling Problem in a Flexible Flow Line’ (GLSP-FFL), optimizes the lot sizing and scheduling of multiple products at multiple stages, each stage having multiple machines in parallel. The objective is to satisf...

We consider the problem of how to run a workload of multiple parallel jobs on a single parallel machine. Jobs are assumed to be data-parallel with large degrees of parallelism, and the machine is assumed to have an MIMD architecture. We identify a spectrum of scheduling policies between the two extremes of time-slicing, in which jobs take turns to use the whole machine, and space-slicing, in wh...

this paper gives a new application of dea to evaluate the scheduling solutions of parallel processing. it evaluates the scheduling solutions of parallel processing using the non-convex dea model, fdh model. by introducing each solution of parallel processing scheduling as a dmu with some relevant inputs and outputs this paper shows that how the most efficient schedule(s) can be identified.

This paper studies the parallel machine scheduling problem subject to machine and job deterioration in a batched delivery system. By the machine deterioration effect, we mean that each machine deteriorates over time, at a different rate. Moreover, job processing times are increasing functions of their starting times and follow a simple linear deterioration. The objective functions are minimizin...

Parallel-machine scheduling research is one of the active fields in the past decade due to its increasing application. Due to the problem complexity, it is a general practice to find an appropriate heuristic rather than an optimal solution for the parallel-machine scheduling problem. The wirebonding workstation is the bottleneck in integrated-circuit packaging manufacturing. Effective schedulin...
