TY - JOUR A1 - Steglich, Mike T1 - LogisticsLab: An academic software for decision-making in logistics JF - Anwendungen und Konzepte der Wirtschaftsinformatik N2 - Logistical decision problems are a part of many courses in the field of logistics, management and operations research. It makes sense to illustrate these optimisation problems using case studies, which can be reproduced by students using suitable software. Often, solver add-ins in spreadsheets programs or general optimisation software are used, which on the one hand requires a high level of knowledge in Operations Research and on the other hand does not always allow an intuitive approach. This article describes the academic software LogisticsLab with which the distributors tie in with the idea of interactive decision support systems to systematically combine the experiences and intuitions of human decision-makers with the possibilities of computer-assisted modelling and optimisation of a wide range of logistical decisions.

The CMPL syntax is similar in formulation to the the original mathematical model but also includes syntactic elements from modern programming languages. CMPL is intended to combine the clarity of mathematical models with the flexibility of programming languages. CMPL transforms the mathematical problem into MPS, Free-MPS or OSiL (see https://projects.coin-or.org/OS or http://www.optimizationservices.org) files which can be used with certain solvers. CMPL is also a part of Coliop3 which is an IDE (Integrated Development Environment) intended to solve LP and MIP problems. CMPL is an open source project licensed under GPL. It is written in C and is available for all relevant operating systems. CMPL and Coliop3 are projects of the Technical University of Applied Sciences Wildau and the Institute for Operations Research and Business Management at the Martin Luther University Halle-Wittenberg.
