This book consists of five chapters. Chapter (1) presents a literature review on the theory, softwares and applications of multiple criteria decision making problems. In chapter (2), we extend TOPSIS (Technique for Order Preference by Similarity Ideal Solution) for solving Large Scale Multiple Objective Decision Making (LSMODM) problems. In Chapter (3), we extend TOPSIS for solving LSMODM problems with fuzzy parameters in the right hand side of the independent constraints. In chapter (4), we extend TOPSIS for solving Interactive Large Scale Multiple Objective Programming problems with...
