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.

In this paper we present stylized facts of the Greek economy that characterize the causes and the consequences of its ongoing crisis. Then, we offer an explanation that can account for those causes and consequences. This explanation is based on the view of Greek society as consisting of two...

The wage premium in the public sector, as measured by the ratio of the average wage rate in the public sector relative to the average wage rate in the private sector, varies considerably across developed economies. And, varies in some developed economies over large periods of time. Further, this...

This paper focuses on the performance of the Greek economy during the period 1979–2001. Following the work of Cole and Ohanian (1999) and Kehoe and Prescott (2002, 2007) this twenty year episode can be characterized as a great depression. We use this methodology and ask whether, given the...

This paper presents the theoretical foundations and dynamic properties of a dynamic stochastic general equilibrium (DSGE) model designed for quantitative policy analysis and counterfactual exercises. The approach of the paper can be summarized as follows. First, we present the model’s...

In this paper, we study the aggregate and distributional implications of a smaller public sector in the euro area. By a smaller public sector, we mean a reduction in public debt and/or cuts in public spending, when such changes in fiscal policy are accommodated by adjustment in various taxes....
