Industrial Engineering methods have been extensively developed during recent years. Thus all mathematical Models have been extended in different directions. The purpose of this book is to provide some discussion about some well-known topics of industrial engineering. The book presents clear and applied concepts and results about different techniques of industrial engineering, with particular emphasis on discussing the merits of such models. First basic description on the methodologies are discussed and more recent developments in optimization models are presented in several cases.The text concentrates on mathematical details and formulations and it is tried to present the theoretical results in a precise manner to make it consistent with the overall level of the book.Prerequisites for the book are some familiarity with concept of optimization and quality control in industrial engineering.
