Production planning systems with AI philosophy

摘要

In this article we present our experience with the development of several systems for computer-aided production planning. The real life production planning tasks can be decomposed into two steps. The latter is the scheduling task, including resource allocation, which must conform to rules, created in the former step. They describe technological conditions that are specific for the manufacturing domain and the factory organization. Thus, the production plan may be viewed as a set of rules that may be considered as constraints for the scheduling task. We focus our analysis on the problem of how to specify these rules. We also show how these plans as manufacturing instruction sequences are structured for diverse production goals. A brief survey of the systems the authors have developed is given as well.
