Modeling and Simulation of Logistics Flows 3 
Discrete and Continuous Flows in 2D/3D

Volume 3 begins with an introduction to which are added four chapters focused on modeling and flow simulation in an environment in 2 or 3 dimensions (2D or 3D). They deal with different cases taken from situations found in the field. A conclusion comes close this third book:

* The different software used in this third volume

* Computer simulation of discrete flows

* Mixed flow simulation

* Flows in 3D and the evacuation simulation

* Flows in 3D for conveying and storage

The conclusion discusses the future developments of the software and their integration into society. At the end of each volume is a bibliography and a list of web links. There is also a glossary explaining some abbreviations, acronyms and some very specific terminology of logistics and operations research.
