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 production-inventory heuristic for the problem which...

A rolling schedule is formed by solving a multi-period problem and implementing only the first period's decisions; one period later the multi-period model is updated and the process repeated. In this paper, we provide a general framework for analyzing rolling schedules, and we examine...

Several papers have been published which present simplified models for the aggregate planning problem which do not yield optimal schedules. They are typically supported with computations that suggest that the resulting schedules produce costs within a few percent of optimum. This note suggests...
