Learning Outcomes

After the successful completion of this course, the students will

  • have acquired an overview of components, designs, and operating modes of intralogistic and interplant logistics systems,
  • be familiar with the basic modeling, analysis, and planning approaches of mathematical programming, discrete event simulation, and queueing theory,
  • be able to apply these to facility location and layout planning problems as well as to the design of production and material flow systems, and
  • be prepared to design real-world systems in inbound, manufacturing, and outbound logistics, following the model-based design approach.

GAMS Models

The following table compiles models and sample data for different planning problems and solution methods that are dealt with during the course. The model and example files contain source code written in the algebraic modeling language GAMS, which can be executed using the GAMS system. The GAMS system includes a greater number of state-of-the-art solvers for several types of mathematical programs, providing optimal or locally optimal solutions.

By modifying the example files, new instances can easily be generated for scenario analyses or when preparing the final course exam. A free demo version of the current GAMS system can be downloaded and installed from the web pages of GAMS Development Corp. You need a demo license for the installation, which can be requested using the form provided on the download web page. By return you will receive an email with the license, which must be added to the system during the installation process following the description in the email. The GAMS models can be edited and solved using a simple text editor called GAMS IDE or the with development environment GAMS Studio. In both environments, the comprehensive documentation of the entire GAMS system is available under the "Help" tab.
