I look for an undergraduate-level textbook on procurement and supply management that is largely organized around (reasonably simple) mathematical models. The texts I have reviewed so far are all description/discussion-based, with minimal to no mathematical content.
To illustrate the idea, the type of text I have in mind would be similar to Cachon/Terwiesch, Operations Management (the undergraduate book), in the level of math, but covers more procurement and supply management topics, e.g., strategic sourcing, supplier selection, and supplier development. That said, any relevant recommendation are appreciated.
