【摘要】 鉴于多目标优化决策中目标优先级确定的困难,本文尝试用专家系统(ES)来辅助决策者确定优先级顺序.系统以企业经营决策,计划编制为对象,构造了一个目标规划模型的优先级排列ES,文中较详细阐述了系统的设计思想,结构,原理及具体实施.系统使用TURBO PROLOG语言开发,用户界面采用全屏幕多窗口下拉菜单.该系统在带有CH卡的IBM-pC兼容机上实现,操作系统为GWBIOS.由于能在一屏幕上显示25行汉字和十分友好的用户界面,使用该系统非常方便.更多还原

【Abstract】 Most research papers on MODM (Multiobjective Decision Making) failed to take into consideration the fact that the objectives are often in conflict with each other and that the problem of assigning priorities to objectives is an ill-structured problem. The problem generally requires a great amount of specialized knowlege of a particular field, which includes both the relevant theoretical knowlege and the valuable judgements of experts that come from years of practical experience. It is believed that Yang in 1990 was the first to explore the possibility of storing such a specialized knowlege in a knowlege base [4]. This paper presents MOPSES as the embodiment of Yang’s idea by applying knowlege engineering and artifical intelligence to MODM. MOPSES, employing TURBO PROLOG (2.0) as its language, has in its knowlege base rules formalized from relevant specialized knowlege, and has a program that can simulate the thought process of experts, i.e., the process of analysis, inference and judgement. Even though objectives are often in conflict, MOPSES can deal with such ill-structured problem and assign priorities to objectives. MOPSES has the following features: 1. It can assign priority ranks to objectives through combining "pair comparison"dialogue appropriately with "question and answer" dialogue. 2. MOPSES is flexible. The objectives (data), rules (knowlege), and question sentences (language) can be revised if desired. 3. All the modules of MOPSES are intergrated. The screen of MOPSES consists of many windows and pull-down menus. Thus it is easy to operate MOPSES. MOPSES has been applied to working out production plan of a factory. In this particular case, there are 9 objectives, 14 rules and 20 question sentences. It takes just a few minutes for MOPSES to get approximately the same result that requires human expert conversant with relevant specialized knowlege to take hours or even days to obtain.更多还原
