In this paper, we put forward a novel human computer cooperation system the scheme producing and evaluation system for the Hall for Workshop of Metasynthetic Engineering (HWME).The proposed system can produce schemes automatically and evaluate schemes effectively whose functions are implemented by the cooperation of human and computers. The system mainly consists of three parts: the scheme framework model, the scheme forming model and the scheme evaluation model. Firstly, the scheme framework model is adopted for group experts to produce a scheme framework to write scheme contents; secondly, the scheme forming model is applied for group experts to write scheme contents and then the computer combine the similar contents to form optional schemes; finally, the scheme evaluation model is introduced to evaluate the optional schemes to obtain the optimal scheme. Experimental results demonstrate that the proposed system is feasible and effective for experts in HWME to solve complex problem which provides a good tool for experts to make decisions and schemes.
