Rationality and Problem Structuring in Design

先前研究的主要目的是使用基于约束的规划策略来描述建筑设计问题的重构。本项目旨在研究设计者在结构设计特别是结构设计问题中的行为合理性。这项研究将分五个步骤进行。首先，利用最优化方法建立空间规划问题结构模型。为了克服空间规划中固有的问题，如值的连续性和问题空间的大小，将利用动态规划技术。利用第一步建立的模型，确定给定问题结构的最优解路径。将使用受试者的协议数据和先前研究的模拟程序HeGeL来显示解释受试者行为的因素，无论是最优，帕累托最优还是非最优。作为黑格尔的新版本，黑格尔- ii将结合早期开发的动态规划功能进行开发。受试者使用的路径和解决方案中的最优性、帕累托最优性或其他形式的“合理性”将与初始建模步骤中获得的结果进行比较，使用黑格尔- II。最后，提出了空间规划的有限理性技术和策略，这些技术和策略可以融入到设计师的过程中。

The primary aim of previous research has been to describe, using a constraint based planning strategy, the restructuring of architectural design problems. The present project aims to study the rationality of designer' behavior in structuring and especially restructuring design problems. The research will be performed in five steps. First, a model of problem structuring in space planning will be developed using optimization. To overcome problems inherent in space planning, such as, continuity of values and size of problem space, dynamic programming techniques will be exploited. Using model developed in the first step, optimal solution paths for the given problem structures will be determined. Protocol data of subjects and simulation program called HeGeL, from previous research, will be used to show factors that explain subjects' behavior, whether it be optimal, pareto optimal or non- optimal. A new version of HeGeL, HeGeL-II will be developed incorporating dynamic programming capabilities developed earlier. The optimality, Pareto optimality or other forms of "rationality" in the paths and solutions used by subjects will be compared against results obtained in the initial modeling step, using HeGeL- II. Finally, bounded rationality techniques and strategies for space planning which can be integrated into the designers' process will be proposed.
