A General Framework for Modeling Production
提出一个通用框架，帮助管理科学家构建确定性的生产流程模型，并重新表述线性规划约束以更准确处理生产提前期，支持非整数提前期和不等长计划期，同时将MRP和CPM纳入框架以揭示其与线性规划的关系。
We introduce a general framework that guides the management scientist's formulation of deterministic models of production processes. Using the framework, we reformulate the constraints of familiar linear programming-based planning models to specifically treat components of production lead time, thereby realizing a more accurate representation of the production process. In addition, the reformulation accommodates noninteger values for lead times as well as unequal-length planning periods. Manufacturing Resources Planning (MRP) and the Critical Path Method (CPM) are recast in terms of the framework, revealing opportunities for model generalization and extension, and their relationship to linear programming models.
