【摘要】：针对产品多学科多目标的设计决策问题,给出了一种融合博弈论和柔性机制进行建模和求解的方法。通过混合博弈来表征学科之间及目标之间的耦合关系,提出了混合博弈模型框架及求解方法。考虑到不确定性和变化的影响,为使产品设计决策具有柔性,引入性能水平满意度函数来柔性表达设计要求,并寻求设计变量的柔性范围解来替代固定值的点解,从而增加产品的柔性;柔性范围解处于可行设计空间内,使各学科性能处于满意水平并靠近期望值,且具有较好的稳定性。利用概率分布对相应的性能变化进行建模,引入设计偏好指数对柔性设计方案进行评价。最后通过减速器算例的设计来验证该方法的可行性和有效性。
[Abstract]:Aiming at the design decision problem of multi-disciplinary and multi-objective products, a method of modeling and solving by combining game theory and flexible mechanism is presented. This paper presents a hybrid game model framework and its solution method by using mixed game to represent the coupling relationship between disciplines and objectives. Considering the influence of uncertainty and change, in order to make the product design decision flexible, the performance level satisfaction function is introduced to express the design requirements flexibly, and the flexible range solution of the design variable is sought to replace the point solution of fixed value. Thus the flexibility of the product is increased and the flexible range solution is in the feasible design space, which makes the performance of various disciplines at the satisfactory level and close to the expected value, and has good stability. The probability distribution is used to model the corresponding performance changes and the design preference index is introduced to evaluate the flexible design scheme. Finally, the feasibility and effectiveness of the method are verified by the design of a reducer.
