Multi-product discrete multi-level supply chain optimization models are critically important to almost any type of industry and especially to retail industry. Investments in raw materials, qualitative goods, spare parts, major and setup costs, inventory holding cost, allowing costs for preservation technology of the perishable multi-products, high operating costs, and decreased production efficiency if these are not controlled. This book is a modest attempt to provide the means of improving one's skill in the field of multi-product discrete multi-level supply chain models with different integrated supply chain models. It also examines comparative analysis, comparative analysis and critically reviews of their performances with integrated strategy under preservation technology. This book is designed as a text on "Multi-product Discrete Supply Chain Models: Aligning Integrated Strategy under Preservation Technology" for post graduate students pursuing courses in Management, Engineering, Commerce, Mathematics, Statistics, and is also suitable for all those studying for professional qualifications such as MBA, MCA, MFC, CA, ICWA, B.Tech, M.Tech, IMBA and CS.
