The conversion of a functional layout into a cellular manufacturing system involves the partitioning of several multiserver work centers. The loss of pooling synergy in this process can be significant, and this paper investigates the impact of several measures to overcome the adverse effects on...

In this paper we consider a certain aggregate production planning model. This model permits regular and overtime production and allows for backordering of goods for a number of periods. Although the discussed model can be formulated as a linear programming problem a special (noniterative) method...

An embedded network within a linear program is, roughly speaking, a subset of constraints that represent conservation of flow. We examine three broad classes of heuristic techniques---row-scanning deletion, column-scanning deletion, and row-scanning addition---for the extraction of large...

Successive Linear Programming (SLP) has been used extensively in the refining and petrochemical industries for over 20 years. This paper concentrates on some recent work at Exxon to unify the treatment of nonlinear terms in "mostly linear" models. We first discuss the source of nonlinearities in...
