Manufacturing Re-insourcing in the Textile Industry: A Case Study
No full textThis article aims to suggest to managers involved in re-engineering projects a method to assess the feasibility of manufacturing re-insourcing.
At first, an analysis of the textile sector is carried out.
Subsequently, a methodology is described, able to assess the feasibility of manufacturing re-insourcing. As a case study, a high production shop is then proposed and sized for the quick response requirements of a company producing young apparel lines on behalf of third parties. Finally,
an economic evaluation is carried out in order to assess the profitability of the re-insourcing strategy
Fault Tree Analysis for Risk Assessment in the Borexino Experiment
No full textThis paper outlines a methodological approach utilizing quantitative risk analyses and cost– benefits evaluation in order to select the most cost-effective options for risk reduction in industrial plants including structural changes and preventive maintenance. The methodology is based on quantification of top events resorting to fault trees, a sensitivity analysis of the probability of occurrence of top events, and a comparison of corrective measures based on cost and effectiveness criteria. The method is applied to a case study represented by the pseudocumene purification plant of the Borexino experiment in order to show its capability. The experiment is located in the Gran Sasso National Laboratory operated by the Italian National Institute for Nuclear Physics
Perspectives of RDF use in Decentralized Areas: Comparing Power and Cogeneration Solutions
No full textPresent EU trends strive to maximize the resources recovery from municipal solid waste thus minimizing the waste amount to be disposed off. Refuse-derived fuel (RDF) production is considered in some countries to be a priority solution even if current market scenarios and consumers scepticism at present limit its widespread utilization. In this work, a comparison has been carried out of two possible RDF utilization alternatives, with particular reference to territorial districts with low population density. After a brief introduction, in which current RDF combustion technologies are illustrated, two possible plant configurations are considered, one concerning only electric power production; the other one combined heat and power production (CHP), using heat for district heating purposes, resorting to two different architectures: single pass-out condensing turbine and back-pressure turbine. Possible application of these technologies to a case study is then proposed, referring to a central Italy mountain territory characterized by a low population density. Then, an economic evaluation has been carried out. Finally, a parametric study was performed in order to define acceptable values for the sale price of thermal energy and the effect on profitability of the incremental investment needed for the construction of a district heating network
