Popis: In this paper we consider the problem of minimizing the mean flow time of jobs to be processed on two non-identical parallel machines. The jobs have a predetermined order, perhaps reflecting their order of arrival and each job has a known processing time (which depends on the machine). The problem is to assign the jobs to machines so as to minimize the mean flow time, with the constraint that the original order must be preserved within the subset of jobs assigned to each machine. It is shown that the problem can be formulated as finding a maximum cut on a structured graph. An efficient procedure for finding this cut is developed and a class of graphs on which the maximum cut problem can be solved efficiently is identified.
