Rapid mathematical programming The thesis deals with the implementation and application of out of the box tools in linear and mixed integer programming. It documents the lessons learned and conclusions drawn from five years of implementing maintaining extending and using several computer codes to solve real life industrial problems. By means of several examples it is demonstrated how to apply algebraic modeling languages to rapidly devise mathematical models of real world problems. It is shown that todays MIP solvers are capable of solving the resulting mixed integer programs leading to an approach that delivers results very quickly. Even though problems are tackled that not long ago required the implementation of specialized branch and cut algorithms. In the first part of the thesis the modeling language Zimpl is introduced. Chapter 2 contains a complete description of the language. In the subsequent chapter details of the implementation are described. Both theoretical and practical considerations are discussed. Aspects of software engineering error prevention and detection are addressed. In the second part several real world projects are examined that employed the methodology and the tools developed in the first part ...
