Many real world applications consist of finding optimal inputs (design variables) to the system that yields in desirable values for stochastic outputs (Responses). Several studies in the literature have suggested approaches addressing these problems but most of them ...

Abstract Time, cost and quality are crucial aspects of each project and tradeoff among them is important for improvement of the overall performance of industrial and construction projects. In this paper we suggest that the quality is added into the traditional time-cost trade-off problem (TCTP) and develop a three dimensional time, cost and quality trade-off problem (TCQTP) with some realistic assumptions. To the best of our knowledge this problem has not been extensively treated in literature yet. In order to deal with the suggested stochastic ...

Abstract Setting of process variables to meet a required specification of quality characteristic (or response variable) in a process is one of common problems in the process quality control. But generally there are more than one quality characteristics in the process. In ...
