This book is designed to offer a lively applied presentation of analytical and empirical tool for Bicriteria in flow-shop scheduling problems. It employs several pedagogical devices to help the readers to learn the new concepts quickly and absorb them fully. Classical flow shop scheduling problems mainly concerned with completion time related objects. in modern manufacturing and operation managements, the minimization of utilization time/rental cost of the machines with minimum make-span are the significant factors for the reason of upward stress of completion on the market. The Bicriteria scheduling problems are motivated by the fact that they are more meaningful from practical point of view.The concepts/illustrated examples format introduced in the text helps the readers to formulate the real world problem easily. The C++ programs under each section will enable the readers and industrial people to apply these concepts practically. The book is mainly oriented towards Bicriteria in flow-shop scheduling. However, the book can be read without any prior knowledge of scheduling theory and may be of interest to all people.
