| Research Abstract |
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.
