In this paper, we present a branch-and-bound approach for solving a two-machine flow shop scheduling problem, in which the objective is to minimize a weighted combination of job flowtime and schedule ...

In this paper we propose an efficient method for this problem, based on a Lagrangian heuristic within a branch-and-bound framework. The Lagrangian heuristic uses a Lagrangian relaxation to obtain ...

Example 5.18: Branch and Bound Trees This example illustrates a nonstandard use of PROC NETDRAW. The TREE option in PROC NETDRAW is used to draw a branch and bound tree such as one that you obtain in ...
