Note—On “A New Look at Production Switching Heuristics for the Aggregate Planning Problem”
指出，先前关于聚合规划问题的简化模型在成本比较时使用了包含大量固定成本的不恰当基准，若仅比较可控的可变成本，这些模型的实际成本比最优解高出20%至30%。
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 that those cost comparisons have been made against inappropriate base costs which include a large fixed cost element. When these models are compared using only the controllable variable costs, costs that appeared to be only one or two percent over minimum turn out to be as much as twenty to thirty percent over the costs resulting from optimal solutions.
