Abstract

It is assumed that the input data for scheduling a set of customers are given as a bipartite graph in some system of units. We consider the problem of composing a schedule of smallest length under the condition of continuous work with no downtime of each unit and their simultaneous actuation. Conditions are obtained for a partition of the edge set of a graph into matchings to form a schedule of the required form.
