Simulation is the best tool used to predict the behavior of real world systems. For the analysis of complex systems, simulation is often used prior to the operation of the system as a mediator for a dynamic situation. This chapter presents the issue of complex systems simulation through Discrete Event Simulation (DES) and System Dynamics (SD)...

In this paper, the authors, consistent with the philosophy of Sustainable Manufacturing, propose a generalized methodology for replacing/supplementing traditional energy sources with renewable energy sources (RES). The methodology, developed stochastically, makes extensive use of Discrete Event Simulation and the Monte Carlo method to optimize,...

The redesign of the operational procedures of a multi-product line, which came into being to operate from a just-in-Time/pure pull perspective, involves a few points of uncertainty and points for management to reflect on. In particular, the unexpected existence of stochasticity linked to certain exogenous (demand becoming unstable) and...

Starting in the second half of last century, researchers and managers have gradually paid more attention to that chapter of decision-making sciences that goes by the name of "Demand Analysis." In the literature today, there are a wide range of templates to allow you to predict future demand for goods and services, with the obvious ultimate goal...

Over the last few years, manufacturing companies have been facing various challenges particularly related to volatile demand and changing requirements from customers and suppliers, requiring new technological roadmaps and interventions in manufacturing systems. In this proactive context, innovative technologies support the creation of...

This paper proposes an innovative system for transporting natural gas from a site of extraction to a site of consumption, through the employ of drone airships. The airships contain slightly compressed methane within the hull volume and employ hydrogen as lift gas. In the paper the authors carry out a comparison between the proposed solution and...

This paper describes an application of the cutting stock problem where great part of the complexity of the problem was actively addressed by mean of a definition of a suitable ontology. It deals with the realization of a series of concentric rings starting from a raw circular flange. The goal is to minimize the scrap and satisfy the customers...

This paper presents a scheduler built around a set of Commercial Off of the Shelf (COTS) functions where the overall complexity have been reduced by a set of pre-processing and post-processing functions. This approach offers many advantages compared to design-for purpose heuristics in term of time to market as well as in term of design and...
