Conceptual design and initial planning of civil engineering systems which are extremely subjective to the decision maker's discretionary powers,require a methodology of overall decision making to perform the balancing act in a multi-criteria objective situation.In the first step of this study,a method of breaking down the decision making process into different analytical models and their proper evaluation using the fuzzy theory has been established.The model forces,however,the perpetual threat of an inexperienced decision maker superimposing the same item more than once during the decision making process and thus degrading the actual purpose of the model.The same situation arises even when the decision maker fails to achieve the best tradeoffs available in a particular situation.Therefore,in the next step,we have tried to correlate the different items and to establish the degree of agreement between the interacting factors,in order to find a process of regenerating the proper judgments through a repeated decision making process.The evaluation problems of an intercity transportation system have been taken as examples to demonstrate the applicability of the proposed method.

土木工程系统的概念设计和初步规划对于决策者的自由裁量权来说是非常主观的，需要一种全面决策的方法来在多标准客观情况下执行平衡行为。在本研究的第一步，建立了一种将决策过程分解为不同的分析模型并利用模糊理论对其进行适当评价的方法。然而，模型强迫一个没有经验的决策者在决策过程中不止一次地叠加相同的项目，从而降低了模型的实际目的。即使决策者未能在特定情况下实现最佳权衡，也会出现同样的情况。因此，在下一步中，我们试图将不同的项目联系起来，并建立相互作用因素之间的一致程度，以便通过重复的决策过程找到再生适当判断的过程。以城际交通系统评价问题为例，验证了该方法的适用性。
