Study on TOPSIS CCMOP Decision Model and Algorithm

In view of uncertainty or unascertained of attribute value, three tasks were accomplished with technique for order preference by similarity to an ideal solution (TOPSIS) based on credibility theory: (1)A weigh calculation model on credibility measure maximum chance-constrained multiple objective programming (CCMOP) was worked out, then it was changed into single objective decision model for calculating weight easily, (2) Considering unascertained of attribute value, a optimistic critical values ordering method based on chance was put forward, (3)A simulation hybrid algorithm of decision model on TOPSIS based on chance constrained was built.
