I. Averbakh et O. Berman, A simple heuristic for m-machine flow-shop and its applications in routing-scheduling problems, OPERAT RES, 47(1), 1999, pp. 165-170
We consider the routing-scheduling version of the flow-shop problem, where
n jobs located at different nodes of a transportation network must be execu
ted by m machines (servers) travelling between the jobs,The objective is to
minimize the makespan. For this problem, we present a simple heuristic and
analyze its worst-case performance.
