Strategic container flow planning: computational test implementation of a model.
Report 93.3.LT.4101, Transport Technology, Logistic Engineering.
This report has been written as sequel to the preceding report "Strategic
container flow planning: a concept for simultaneously optimizing
flows of full and empty containers" [Report 93.3.LT.4029,
Transport Technology / Logistic Engineering, Mechanical Eingineering and Marine
Technology, Delft University of Technology]. It entirely focuses on the
computational implementation of the model as it has been developed in the
before mentioned report. The mathematical formulation of this model is briefly
The primary objective of the implementation is to gain insight in the
actual computation times corresponding to several possible optimization
strategies, when applied to network problems with varying characteristics.
Most of the testing was conducted, using the IBM Optimization Subroutine
Commercial optimization software usually supports input in a special industry
format, commonly known as the MPS-format. The procedure of generating test data
in this special format is discussed in this report.
An analysis of the results is presented, as weIl as a brief comparison between
several optimization software packages and different platforms.
