板翅式换热器模糊优化设计

应用结构模糊优化理论对板翅式换热器进行多目标优化设计；给出了构造隶属函数及确定目标函数权重的方法，通过线性加权法将多目标化为单目标求解。应用此软件设计了一台换热器，其实际使用结果表明完全达到设计要求。

FUZZY OPTIMUN DESIGN OF PLATE-FIN HEAT EXCHANGERS

Multi-objective optimum design of plate-fin heat exchangers by fuzzy optinum theory was developed. A reasonable procedure of making the grade of membership function and identifying the weight value of objective function was propsed. Based on the method of linear weighting, it was easy to solve the multi-objectics optimization. The software compiled by themethod had been used to design a plate-fin heat exchanger. The practical use results showed it satisfied the request of the design.
