We present a new network aggregation/disaggregation approach for solving a multiperiod, network model with bundle (Generalized Upper Bounding) side constraints. The model describes production planning and distribution problems. Instead of solving the original multicommodity problem, we transform...

This investigation considers certain issues regarding the optimal design of unpaced production lines with variable processing times. Under certain assumptions, including an equal allocation of buffer storage space between the respective pairs of stations, it is known that the optimal allocation...

This note develops a fathoming procedure for the Dynamic Plant Layout Problem (DPLP) discussed by Rosenblatt (1986) in this journal. This procedure can be used to reduce the number of candidate static layouts to be examined. An important feature of our procedure is that a feasible dynamic...

A mixed-model manufacturing facility running under a Just-in-Time (JIT) production system is controlled by setting the production sequence of the final assembly process. This sequence is set to achieve the primary goal of an organization operating under a JIT system, which is to maintain a...

The facility layout problem is important in the modern manufacturing environment because increased machine flexibility and product diversification create additional complexities in scheduling and material handling. An important first step in facility layout is the determination of which machines...

In this paper a branch-and-bound procedure is described for scheduling the activities of a project of the PERT/CPM variety subject to precedence and resource constraints where the objective is to minimize project duration. The procedure is based on a depth-first solution strategy in which nodes...
