Il risparmio energetico nei regolamenti edilizi comunali
No full textLa Direttiva 2002/91CE introduce la certificazione energetica. Quale paese membro della Comunità l'Italia e' tenuta ad adeguare la propria normativa. Il Regolamento Edilizio potrebbe essere lo strumento adeguato ad inquadrare correttamente le procedure di certificazione nel rispetto di una griglia comune al territorio nazionale,, che lascia spazio alle caratterizzazioni locali
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Analysing reusable and disposable containers costs in food catering supply chain networks using optimization
Full text linkNowadays, strategies to minimize environmental impacts throughout food supply chains (FSC) are hotspots for academics and practitioners. A relevant portion of such impact results from food primary and secondary packaging. Food Catering Supply Chain (FCSC), made of multi-stage logistic networks, represents a challenging scenario for minimizing packaging disposal. Indeed, the booming widespread of reusable plastic containers (RPCs) in the FSC suggests the adoption of such containers to foster reuse and prevent material waste with respect to disposables. This paper explores the application of RPCs in the context of FCSC by proposing a MILP model that aids supplier and package choices considering the reusable package-pooler and the catering system networks. This model minimizes operational and logistic costs whilst optimizing the packaged product’s flows. A case study provides the model’s validation and offers insights for future research investigations. Results show that increasing the numbers of supply chain actors and the size of the logistic network make the adoption of RPCs economically convenient
A support-design framework for Cooperative Robots systems in labor-intensive manufacturing processes
Full text linkManufacturing processes and industrial systems gradually change their traditional layouts and configurations, preparing to introduce novel integrated human-robot technologies as collaborative robots and exoskeletons. Whether mass customization of lot size and the production mix discourages the adoption of capital-intensive automation, collaborative robots become affordable and effective and a hotspot of the debate on manufacturing systems. This paper provides a novel support-design framework for the cooperative robot system in labor-intensive manufacturing processes to aid layout and task scheduling design. Through an iterative closed-loop methodology, this framework explores the impact of a cooperative robot in a labour-intensive manufacturing system like the production facility of a food service company. The framework leads the designer through the re-layout of the end-of-line, the economic and technical feasibility analyses, using simulation to estimate payback and ergonomics benefits for workers. Within the proposed layout, we state that adopting a cooperative cobot for the end-of-line is affordable and ergonomically convenient without representing a safety threat for workers. The testbed confirms the framework as an enabling tool for human-robot technologies integration in current manufacturing systems under budget and workers-driven constraints
