Optimization problems with uncertain parameters are a kind of familiar and complicated optimization ones in practice.Considering the case that constraints and objective functions both contain interval parameters,the efficient chance solution and a deterministic optimization proposition on the above problems are proposed based on the definition P-reliability measure.With this method,decision makers can obtain satisfaction solutions by specifying relative parameters of the deterministic optimization problems ...
