D. Dewerra et al., SCHEDULING PERIODIC JOBS COMPACTLY WITHIN A FIXED TIME PERIOD IN OPENSHOPS, INFOR. Information systems and operational research, 32(2), 1994, pp. 110-120
A graph-theoretical model for a periodic scheduling problem in an open
shop is described; a given production requirement must be satisfied f
or each period of k time units. Necessary and sufficient conditions fo
r the existence of such a schedule are given under some compact new co
nditions (each Production job must be processed without any waiting ti
me ana processors must work continuously during a production phase).
