On the basis of the specific complexity, ambiguity and uncertainty of the selection of construction scheme for multi-attribute decision making system, a new evaluation method based on catastrophe theory is proposed and applied to the decision making for Construction Scheme. Firstly, the multi-layer assessment objects are analyzed with this method and property values of evaluation indexes are quantified. Then, the ultimate catastrophe function is obtained through different catastrophe models. In order to calculate, integrate and obtain the total value of Catastrophe, the decision making can be carried out. The outcome from concrete application of construction scheme optimization indicates that it is reasonable and has avoided the problem of calculating coefficient of weight subjectively with clear thread and simple calculation.
