The study presented derives from the request of the management of an Italian important pediatric hospital to reorganize the patient acceptance service. The authors to address the analysis had built a stochastic discrete event simulation model through which it was possible to study the behavior of the system under consideration in the different...

Optimization of maintenance services of a company working in the gas metering sector is investigated. In particular, daily tasks of operators are optimized by exploiting the paradigm of vehicle routing problems with a set of predefined time windows that overlap one with the others and four competing objectives to take into account. First, an...

Construction projects are characterized by great uncertainty. Appropriate risk analysis techniques are required to estimate the adequate coverage level against the occurrence of extra costs to increase the progress of the project in the tenders. The project margin increases when an excessive provision leads to a more comprehensive coverage of...

The cost contingency estimation is an essential phase in the risk management, especially when the regime of performance is stochastic. This research proposes a probabilistic model to estimate project cost contingency by considering the fact that any risk can occur on a variety of values in terms of economic impact. The impact of risks on the...

The proposed application is related to an Italian small factory that produces, assembles, and sells mechanical components for awnings. In such factories BPR (Business Process Engineering) usually takes place without the support of Modeling & Simulation although such methodologies have proved to be very effective and helpful. Main reasons for...
