There are very few books out about how to model problems in linear and integer programming. Hugh Williams book “Model Building in Mathematical Programming” is one. The documentation that comes with commercial software is another resource. Dash Optimization has made their “Applications of Optimization with Xpress-MP” available for free download. This book goes beyond the standard “3 variable 2 constraint” models found in so many textbooks.
Thank You for the info. I am a student of OR and all the courses are too theoretical and modeling isn’t taught at all. I received the Hugh Williams book from Amazon and so far it is very interesting.
