Fidelity management and evaluation in logistics system

This paper discusses fidelity of simulation in logistics systems. A method to manage fidelity is developed, and three standards according to which fidelity levels can be described are presented. To quantify the differences between different fidelity levels, a Book Retrieval Module in a Book Distribution Center Design Project is studied, three models with different fidelity levels are built, and a method to calculate the differences is given. A system of evaluation index is developed. Some suggestions about fidelity management and evaluation are given at last.
