Simulating Transportation over a Wide Area During a Regional Crisis
No full textThe paper proposes the use of simulation as support for evaluating crisis over wide areas; this demonstration is focusing on a single layer of operations (road transportation) for a whole state, simulating in details each single operation; despite the dimension of this scenario this study demonstrates the potential of Modelling & Simulation in this context as well as the capability of integrating complex aspects (i.e. logistics, human flows, regular activities, emergency conditions, inter relations with other layers such as air transportation)
Simulation as Decision Support System for Managing Power Plants Pool Maintenance
No full textThis work is focusing on advanced techniques, including artificial intelligence, applied on a simulation model used as a DSS for supporting management and decision making in complex planning of maintenance for power plants pool
Potential of Simulation in Nanosurfaces Formation
No full textMontecarlo simulation allows to analyze
diffusion-limited surface deconstruction; in
this paper this approch is presente in a three
dimensional approach. The model include the
possibility to consider the influence of an
external force field to be combined with the
Brownian and deterministic components of
the etchant particle motion. The results
highlight the the time trend of the surface hull
variance; the paper include the analysis of
several solid substrate dimensions in relation
to different values of the force field
parameters affecting etchant particle
trajectories; the model results are validated,
verified and compared with the analytic
approaches related to surface growth
dynamics

No full textThis paper regards the analysis of the development of a logistics and transportation network concerning a steel plant. The main goal is to search for the best scenario that allows to supply the plant and to
distribute all the finished products to final customers in the most efficient way. To this aim, a proper simulation model has been developed and implemented utilizing Logistics Re Designer (Lo. R. D.) software
tool. More specifically, three different transportation networks have been created: two “single” modal choice scenarios - by road or by rail – and an “intermodal” one. Another system variable regards the production capacity of the steel plant: three different types of capacity have been considered; so in total nine scenarios have been taken into consideration. The results obtained indicate that the intermodal solution is the most suitable to be adopted both in terms of total time – and consequently costs - and resources required to perform all the necessary operations. Future research will focus on the improvement of the solution found and on the development of an economical analysis
Using a System Dynamics Approach for Designing and Simulation of Short Life-Cycle Products Supply Chain
No full textThis work is part of an Italian National Research Project embracing different aspects of a short life-cycle
products supply chains: its modeling, its resiliency and its competitiveness. In fact, this particular kind of
products, like fashion goods, toys or electronic devices, have different characteristics compared with
long-medium life cycle products and this implies a quite different management as well as competitiveness
factors to take into account. Starting from the modeling of a supply chain of this kind, utilizing the Powersim
Studio Software implementing the System Dynamics methodology, with the goal of showing its
behavior under specific scenarios, some vulnerability causes have been considered in order to make the
supply chain more resilient. Finally, the competitiveness dynamics between two companies producing
short life cycle items has been modeled and analyzed
