Modeling of Computer-Based Decisions and Optimization in Design Process

设计的一个重要方面是将相互冲突的目标平衡为一个统一的目标。因此，设计者可以被视为负责确定最符合总体设计目标的备选方案的决策者。这项研究的重点是以一种可操作的形式表示设计目标的方法，适合于标准的优化公式。这项研究的目的是帮助理解设计中的决策以及这一过程在计算中的形式化。研究将集中在决策过程正规化的三个方面：为聚集设计目标和表示偏好结构构建业务模型；将决策模型和优化算法纳入独特的计算过程；以及在基于规则的计算环境中管理这些信息。该方法依赖于设计评价准则的模糊集表示，并利用敏感度和约束活动信息来促进优化和决策之间的沟通。在计算环境中实施这些想法将促进和组织对设计决策过程的理解。

An important aspect of design is the balancing of conflicting objectives into a unified goal. Thus, the designer can be viewed as a decision maker charged with identifying alternatives that best match the overall design objectives. This research focuses on methods to represent design goals in an operational form, suitable for standard optimization formulations. The goal of the research is to contribute to the understanding of decision making in design and the formalization of this process in computations. The research will focus on three aspects of the formalization of the decision process: the construction of operational models for the aggregation of design objectives and the representation of preference structures; the incorporation of decision making models and optimization algorithms into a unique computational process; and the management of this information in a rule-based, computational environment. The methodology relies on fuzzy set representation of criteria for design evaluation and on the exploitation of sensitivity and constraint activity information to facilitate the communication between optimization and decision making. The implementation of these ideas in a computational environment will promote and organize the understanding of the process of decision making in design.
