Which is the best location of a production and/or distribution center? What about the stock inventory capacity and its geographical location? What about the allocation of demand of products from the final customers level to the source/production level passing from the wholesalers, the regional distribution centers level, central distribution centers, etc.? Logistics and supply chain management need models, methods and tools to face these issues simultaneously and eventually sequentially in agreement with a top-down modelling approach, which measures the level of interdependency between the very large number of involved decisions when the complexity is prohibitive. This paper deals with effective tools developed and applied by the Department of Industrial Engineering to support strategic, tactical and operating decisions in logistics and with a focus on feasibility in real application

The globalization of the food trade has bridged the barriers between production and consumption without respecting the balance of natural resources, resulting in enlarged gaps between developed and developing countries. In the food sector many issues affect the three dimensions of sustainability: economic, environmental, and social. These include land-use change and deforestation to widen farms, pastures, and biofuel cultivations, land grabbing to establish intensive agriculture, clean water consumption, soil and air pollution, lack of supply chain infrastructures, volatile prices, and climate change. Together these issues make current food supply chains (FSCs) unsustainable over the long term and challenge the future of the food industries and society as well. Such issues also reveal the lack of connections and coordination among actors involved in FSCs and open debate about the neglected role of the physical and logistic/distribution infrastructures in addressing long-term sustainability targets. This chapter illustrates a hierarchical framework aimed at modeling production and distribution food ecosystems through a set of interdisciplinary parameters and decision variables. The decision levers identified in this framework describe how the food ecosystem behaves according to an input-output flow analysis. The framework formulates a set of planning decision problems via mixed linear programming. The definition of the inclusive food ecosystem inspires collecting multidisciplinary parameters that impose collaboration between decision-makers. Furthermore, as part of the ecosystem, logistics and distribution processes are involved in the planning issues beyond the common perception that sees an FSC as a sequence of independent stages.

Thus, production systems must be extremely flexible. Companies typically exploit assembly lines to manufacture produces in great volumes. The development of assembly lines distinguished by mixed or multi models increases their flexibility concerning the number of product variants able to be manufactured. However, few scientific contributions deal with customizable products, i.e., produces which can be designed and ordered requiring or not a large set of available accessories.This manuscript proposes an original two-step procedure to deal with the multi-manned assembly lines for customized product manufacturing. The first step of the procedure groups the accessories together in clusters according to a specific similarity index. The accessories belonging to a cluster are typically requested together by customers and necessitate a significant mounting time. Thus, this procedure aims to split accessorie...

Their use, in lab tests and analyses, allows to study the effect of solar radiation on both materials and components. This paper focuses on the effective design of the ellipsoidal reflector for concentrating solar simulators. A Monte Carlo ray-tracing approach is proposed to study the reflector geometric configuration maximizing the target incident radiation and optimizing the radiative incident flux distribution. Developed raytracing model includes the main physical and optic phenomena affecting light rays from the source to the target area, e.g. absorption, deviation, reflection, distortion, etc. Proposed model is integrated to a Monte Carlo simulation to properly design the ellipsoidal mirror reflector of a small scale solar simulator based on an OSRAM XBO® 3000W/HTC OFR Xenon short arc lamp as light emitting source. Several scenarios are tested and the main obtained evidences ...
