Ports, as well as other important transportation infrastructures like railways, motorways and airports, play a great role in the economy of a nation, because, if properly managed, they can strongly affect the Country competitiveness and its economic development; this is true especially for Italy, which can take great advantage from its geographic position of peninsula. In fact Italy can heavily exploit seas using the so-called "Seas Highways" system - a series of alternative links between Northern and Southern Italy, and also Mediterranean Countries - devoted to lighten vehicular traffic on the most important Italian motorways (like the Milan-Naples or the Adriatic Motorway, just to quote two of the busiest), but also to reduce atmospheric pollution and to guarantee a cheaper way of transportation, especially for goods which are not perishable. Although also European Union is strongly recommending this solution, even inserting Seas Highways inside the Pan European Corridors (as "Corridor 21"), the Italian ports have many difficulties to face the international competition, especially with Northern Europe ports, despite their privileged position on the routes coming from the Far East, because of different reasons, first of all the inadequacy of the infrastructures internal and external to the ports (especially railroads, exploited a little respect to other European Countries), the high fragmentation of the Italian port realities (every Port has in Italy its own Port Authority), that causes fund dispersion and organizational problems, and a regulation out to date. All this problems are also amplified by the actual international economical crisis, which contributes to increase competition among the ports. For these reasons the authors are presenting a project proposal, in cooperation with the Italian University and Scientific Research Ministry, devoted to analyze the current situation of Italian ports and logistic facilities, underlining points of strength, points of weakness, opportunities and criticalities and analyzing the common factors of behavior of the ports considered. This is a prerequisite to define a simulation model implemented using the System Dynamics methodology, which is suitable for the study of high uncertain scenarios, as the Italian port reality is, allowing the formulation of so-called "What if" analysis. The aim of this model is to simulate the effects of the infrastructural, organizational and normative changes on the Italian port system, acting as a powerful Decision Support System (DSS) for all the stakeholders involved in the system, in order to identify a common solution devoted to improve Italian ports competitiveness. Moreover, the authors provided a deep literature review on works concerning port competitiveness worldwide, analyzing what has been done in the Far East, in India and in Europe, in order to find interesting starting points for the research proposed.

This paper discusses about methodologies for governing and managing projects of system integration, providing a new way of considering such projects' lifecycle avoiding common pitfalls. In this work Authors provide an overview of common issues in complex IT projects, focusing in particular on criticalities derived from such projects and proposing simple solutions on the basis of experiences and studies led on big System Integration projects involving international companies.

The paper describes shortly the architecture of a complex system for managing back office activities and store management including MRP, Demand forecasting, stock evaluation system from the logistics and financial point of view, integrated in a company ERP. Simulation was the way to properly define the most suitable algorithm for demand forecasting among the many complex combinations proposed by default in the ERP Central Component plus the ones proposed by key users. This architecture was applied in a complex retail chain involving different classes/clusters of point of sales and selling many different sorts of goods (grocery, food, clothing, electronics, home goods etc.).

Maintenance is an important aspect in order to guarantee the efficiency of industrial facilities. For power plants the high availability ratios can be obtained only with preventive maintenance but the result costs increases rapidly. In order to reduce the cost level of the maintenance activity, on-condition maintenance is carried out on an increasing subset of components. Only using appropriate reliability models can identify the optimal mix between preventive and on-condition maintenance. Some time the data required by such models are inadequate or missing and the performances of the implemented system can fall quite rapidly. The authors propose an innovative approach based on a hierarchical Montecarlo simulator able to estimate properly the power plant reliability and, at the same time, improve its performances by a fine-tuning of its parameters. A real life case study is than presented and discussed, even with economical consideration.
