The book "Multicriteria Analysis in Engineering" provides a comprehensive introduction to the optimization methods used in engineering. It highlights the challenges professionals face when formulating optimization problems, particularly in defining feasible solutions and the associated constraints. To overcome these difficulties, the Parameter Space Investigation (PSI) method is introduced, which has been specifically developed for the correct formulation and solution of engineering optimization problems. This method is supported by the MOVI 1.0 software package, with a tutorial version included in the book. The PSI method is applicable in a variety of fields, including design, identification, prototype development, and the analysis of large systems. The book is aimed at researchers, students, and engineers engaged in mathematical modeling and industrial mathematics.
