I recently came across a book on Abstract Algebra by Charles Pinter. I am surprised by its simplicity to explain the concepts.
I am very interested in OR problems in supply chain management. I can imagine that there are a lot of OR problems at every stage of the supply chain, e.g., inventory management, order fulfilment, pricing, matching, etc. I am wondering if there are books that can help me learn supply chain management and mathematical formulation of these problems.
