A Knowledge Based Decision Support System for Setup Reduction
针对企业换模时间缩减投资决策的复杂性问题，开发了一个结合启发式与程序化知识的决策支持系统，帮助管理者避免过度或不足投资，提升制造效率。
ABSTRACT The issue of setup reduction is important for firms seeking to incorporate advanced procedures and concepts such as flexible manufacturing systems (FMS) and just‐in‐time (JIT) manufacturing to improve manufacturing productivity. Investing adequate amounts in setup reduction is a complex decision affected by many factors including the existing level of automation, worker characteristics, product features, and the manufacturing environment. The consequences of improper investment (i.e., over‐ and underinvestment) includes possible disruption of manufacturing operations as well as wasted resources. Much of the knowledge involved in the investment decision is heuristic and experience‐based, and takes on greater significance when the form of the setup reduction function is not known a priori. This paper describes the development of a knowledge‐based decision support system (KBDSS) that combines both heuristic and procedural knowledge to provide support for the setup reduction investment decision. The system uses codified manufacturing expertise to improve both the accuracy and effectiveness of setup‐reduction decision making. Use of the KBDSS is illustrated by two examples based on disparate manufacturing contexts.
