WebMay 1, 2008 · Section snippets Problem definition. We consider a toolgroup of m identical machines in parallel denoted by Pm.Each of the machines can process only one job at a time. There are a total of n jobs arriving at different times to the toolgroup. Each job j has a processing time p j, arrival time or ready time r j, due date d j, and a weight, w j.When a … WebAug 1, 2011 · This paper considers a different version of the parallel machines scheduling problem in which the parallel jobs simultaneously require a pre-specifiedjob-dependent number of machines when being processed, and proposes a semi-definite relaxation algorithm and uses the rounding algorithm for graph coloring.
