We analyse the problem of executing periodic operations on a minimum number of identical processors under different constraints. The analysis is based on a reformulation of the problem in terms of graph colouring. It is shown that different constraints result in colouring problems defined on different classes of graphs, viz. interval graphs, circular-arc graphs and periodic-interval graphs. We discuss the complexity of these colouring problems in detail.
