Production Switching Heuristics for the Aggregate Planning Problem
Mellichamp, Joseph M.; Love, Robert M. - In: Management Science 24 (1978) 12, pp. 1242-1251
A number of approaches to the aggregate planning problem have been proposed in the literature, yet experience suggests … that industrial concerns seldom use these models in actual planning situations. This paper describes a modified random walk …

Exact and Approximate Cost Functions for Product Aggregates
Zipkin, Paul - In: Management Science 28 (1982) 9, pp. 1002-1012
We show that certain large, multiproduct problems can be well approximated by smaller models of the same form, representing only one aggregate product (or a few such products). This reduction follows from a new technique to approximate the minimal cost of a special allocation or "disaggregation"...

The Two-Product, Single-Machine, Static Demand, Infinite Horizon Lot Scheduling Problem
Boctor, Fayez Fouad - In: Management Science 28 (1982) 7, pp. 798-807
In this paper, we deal with the two-product, single-machine, static demand, infinite horizon lot scheduling problem. After a quick review of the literature, the necessary and sufficient conditions for feasibility are derived without imposing any preliminary requirements. Then, an optimal...
