In order to properly address the topic, a reference framework is proposed. The framework provides a context analysis of major industrial and societal challenges which affect grand challenges as identified by the European ‘2020’ strategy. Knowledge exploitation of Key Enabling Technologies and Sustainable Urban Development are considered major industrial and societal challenges which, in turn, are significant opportunity of growth for industry. Major gaps between industry needs and competence provided by Industrial Engineering (IE) curricula are identified. A multi-university collaborative network could be the appropriate answer to bridge educational gaps and pursue a unifying view of IE in the EU, respecting educational and industrial traditions of different Countries of the European Higher Educational Area (EHEA).

However, for many years the influence of human behavior on production system performance has been underestimated and a lot of unrealistic assumptions have been used to simplify the human component modeling. Nowadays, population aging is acknowledged as a global trend. Among individual factors impacting on workers' performance, high attention is being paid to the age from scientific community, policy-makers and business leaders. The aim of this paper is to provide some highlights about the main scientific literature findings, regarding aging effects, in a quickly consultable and synthetic form; the elements characterizing human performance could then be included in models and ergonomic evaluation tools. In the initial part of the paper, demographic aspects and their implications on workforce composition are illustrated; successively, a state of the art of human behavior modeling is provided and main findings on age-related performance characteristics are summarized.

Constant voltage and frequency are obtained only by controlling the generator appropriately. The control system is supposed to be optimised so that the system operates at the highest efficiency. In order to improve the total efficiency even further, a gear-box to vary the gear transmission ratio between the turbine and the generator has been considered. A "Monte Carlo" type simulation has been used to analyse the operation of that system over a one year period. The model is based on a probability density function of the wind speed derived by statistical data concerning a given location and on the probabilistic curve of the load required by an isolated location. The cost per kW h for different dimensions of the main components has been evaluated and the optimum configuration has been identified. 0 1997 Elsevier Science Ltd.

In actual logistic systems, transport costs play a key role, and in case of stochastic variability of product demand and/or supply lead time, a safety stock is required. Transport and safety stock costs affect the solution of the lot size problem. Recently, wide attention is being paid to sustainable manufacturing and in particular on negative effects of transport. Transports are the main source of air pollutant emissions in EU and are expected to increase in magnitude in the future. Costs evaluations of transport emissions are defined in EU documents based on Kyoto protocol. When transport environmental costs are considered in the logistic cost function a new lot-sizing problem can be defined. In [1], the Sustainable Order Quantity (SOQ) analytical model is proposed aiming at identifying optimal lot-size and transport means which minimize the logistic and environmental costs in case of a deterministic product demand. In this paper, the authors propose an SOQ model in case of stochastic variability of product demand. Analytical model solutions rely on sustainable (in terms of both logistic and environmental costs) order size, transport means and safety stocks. Results obtained in a full case study from automotive supply chain case study are presented.

In the view of a urban sustainable development, a strategic role in the governance of the smart City is played by waste integrated management systems (IWMS). The raising complexity of a IWMS relies on the high number of design and management variables and relationships related to collection, treatments and disposal phases. Waste management practices can affect greenhouse gas emission by influencing energy consumption, methane generation, carbon sequestration and non-energy related manufacturing emission. A decision support system can be modelled aiming to evaluate and minimize the carbon footprint of a IWMS. The model proposed goes beyond the existing technical and organizational solutions outlining the different options in a much broader view concerning both waste collection and treatments.

In the last decade urban planning and management had accomplished, or will do it, innovations in order to meet the challenges posed by sustainable development. Reduction of 20% of GHG emission, the achievement of 20% energy demand by renewable energy together with an increase of 20% of energy efficiency are targets foreseen by EU. In this scenario a strategic role is played by municipal waste integrated management system (MWIMS). The matter is becoming increasingly important as a results of the growth of urbanization rate: the raising complexity of a MWIMS relies on the high number of design and management variables and relationships pertaining to collection, treatments and disposal phases. Waste management practices can sway greenhouse gas emission by affecting energy consumption, methane generation, carbon sequestration and non-energy related manufacturing emission. In this context, a sustainable waste management system allows a reduction of negative impacts on environment. The purpose of such a study is to propose a decision-making framework aiming to minimize the carbon footprint of a MWIMS. The model goes beyond the existing technical and organizational solutions outlining the different options in a much broader view concerning both waste collection and treatments. A mixed integer linear programming model , has been applied to a full case study concerning Bari. The study is carried out within the research project RES NOVAE (Reti, Edifici, Strade ‐ Nuovi Obiettivi Virtuosi per l’Ambiente e l’Energia). The strength of the framework results in supporting public decision making, a complex process due to the number of decision variables and their implications on economic performance. Results exhibit the effectiveness of the model also in pointing out opportunities non yet evaluated.

Source reduction, generation, recovery, and disposal constitute interactive elements of an integrated MSW management systems. The chapter aims to support both technicians and public authorities in order to design a sustainable integrated MSW management system. Starting from literature review about the application of sustainability concepts in MSW management, a comparison between strategies for more sustainable MSW management has been compared in order to point out common features and differences. Collection services have been evaluated as the most critical activity in the both context. Next, integrated MSW management systems that are the operational way for applying sustainability concept in MSW management have been deeply analyzed. Finally, a reference model for designing sustainable collection and recovery services is detailed.
