In production systems modelling usually acts to system simulation by discrete events. The present paper exemplifies this, using the Queuing System Simulation module of the WinQSB software.

Extensive research is now under way around the world to develop advanced technologies to enhance the performances of infrastructure systems. While these technological advances are incremental in nature, they will eventually lead to structures which are distinctly different from the actual...

The CRAFT Method was at the basis of the development of the heuris-tic commuting models, in which one starts from an initial emplacement of units that is successively improved, through the successive commut-ing of units among them on the basis of some criteria. In the present paper we have...

With the help of the simulated process, it could be realized all kind of experiments on a model. It could be tested lots of ideas, a returning in time to make possible remaking of manipulation scripts of some key variables with the purpose of observation based on experiments the effect above...

The paper brings up many explanations regarding the understanding of connections between causes and effects, through simulated models. It wishes to establish and simulate some scripts witch concur to the development of a business.

The article analyses recent developments in business investment for a large group of EU countries, using a broad set of analytical tools and data sources. We find that the assessment of whether or not investment is currently low varies across benchmarks and countries. At the euro area level and...
