Enterprise Eco-watching and Appraisal: Asset Modelling and Sustainability Assessment

AbstractAt the millennium turnover, the ecology globalisation shows the impeding threats of over-depletion/pollution: the sustainable growth requires supply-chain visibility, resource bookkeeping and renovation planning. The lifecycle starts when the idea of a product is born and lasts until complete disposal after realisation and operation. In the musts’ specification/analysis, the basic design (global plan, detailed design, assembly design, etc.) are followed by manufacturing, assembly, testing, diagnostics and operation, advertising, service, maintenance, etc.; then, disassembly and firing are scheduled, requiring reclamation and recovery, by re-cycling (material reprocessing) or re-using (part refurbishing). The present paper provides pilot clues for understanding the product-process agendas, using the TYPUS metrics and the KILT model, developed by the authors, in previous works

Influence of Start-up Management on the Residual Life of a Large Steam Turbine Shaft

The liberalization of electricity market in Europe led to a growing competition between energy producers, making crucial the ability to optimize the management strategies of power plants. Combined Cycle Power Plants (CCPP) have to operate in a flexible way, with frequent and rapid variations of the power produced, in order to quickly adapt to the frequent changes in load imposed by the demand. Nowadays, they typically operate in cycling mode with daily start-up and shut-down. The components of the plant are subjected to great cyclical variations in temperature, which induce stresses on materials, especially during the start-up phases. The present activity concerns the assessment of life consumption -caused by these operations- on the rotor of the steam turbine of the CCPP (800 MW) inside the Tirreno Power thermal plant located in Vado Ligure, Italy. The aim is to draw a set of curves representing the percent life expended per cycle as a function of rate of steam temperature change and magnitude of the overall temperature increase. These curves are called Cyclic Life Expenditure curves (CLE). In the future, the developed methodology will be used to reduce the start-up times, keeping under control the life consumption of the rotor and optimizing the maneuvers that generate thermal transients

ESDA2008-59395 LIFECYCLE MONITORING FOR THE AUTOMOTIVE ECO-SUSTAINABILITY

ABSTRACT The growth sustainability requires dramatic changes to lower the natural resources consumption and the surroundings pollution, by recovery/remediation processes. The EU policy aims at the extended producers/suppliers responsibility, with effective charges on the products allowed to be put on the market, used and called-back, in view of the properly small impact and transparent lifecycle acknowledgement. This leads to «extensions» in designing the new offers with integrated monitoring and service functions. The design for the lifecycle eco-effectiveness is accomplishment, better qualifying the far-seeing companies according to the EU eco-policy. The idea is to reach the duty visibility, by the extended plug-and-play concept, based on series of integrated design options, assigning the structural and functional modules, for the operation monitoring, the reliability assessment and the impact appraisal. This instrumental setting includes intangible information/communication aids, to confer ambient intelligence abilities. This way, the on-process visibility is assured, and exploited for on-duty servicing and end-of-life processing. The example case chosen deals with the critical situation of the parts manufactured in plastics, which are deemed to represent most relevant portion in the cars to come. The following recovery options are possible: -the reuse of the reconditioned items, according to suitably assessed life-extension opportunities; -the recycling of the warn-out components, with the regeneration and reusing of the materials; -the thermal recovery of residual stuffs, within careful handling and pollution-safe warnings ; -the reduction to registered ASR, automobile shredding residue, within the EU directives limits. The on-board information system includes, as innovative feature, the resort to identifying tags or labels, to be read and written through wireless links. The technology exploits cheap and compact supports, allowing the labelling of the component, from production, to lifecycle, with an identifying code. The RFID, Radio Frequency Identification Device, is privileged, as ideal means for the component traceability and the history, use modes/styles and cumulated issues storing.

Progress Continuance Sustainability

The \u201cprogress\u201d is the outcome of the intentional alteration of the wild surrounds to establish enhanced friendly life conditions for men. The swop entails the earth inhabitants, matching extant peoples by the \u201csocial breakthrough\u201d, leading to \u201ccollective orders\u201d or human civilization political endings. This identifies as the public range relational setup, by which the men enable planned progress, via culture/ethics artifacts, inventing authority, legality and management, to support trade and business, in view of plus-value arrangements. This \u201csocial breakthrough\u201d entails hierarchic arts to assign sovereignty rules, with acknowledged leadership. In basic construal, the survey links cosmos\u2019 destiny to men\u2019s wherewithal, that is, the ability of agentive and rational choice of controlled life-quality behavioural traits occurs because of suited \u201canthropic principles\u201d. The legality arts, on the political endings, here, confine into split-sovereignty outfits

Understanding the Growth by KILT Model and TYPUS Metrics

The goal of the study is investigating the odd claim of the human civilisation, which modifies the wild natural surrounds by synthetic alterations, defined improvements, bestowing «value added». Indeed, the history seems sanctioning that the «life-quality» on the earth has been expanding, with enhanced chances and increased resources, compared to the native prospects of the wilderness. Only at the millennium turnover, the ecology globalisation shows the impeding threats of over-depletion/pollution, exceeding the extant recovery and reclamation capabilities of the environment. The new imperative turns to be the «sustainable growth», with caginess in defining if the trends can be positive, being conditioned by the empowered recycling, retrieval and renovation measures. In fact, sustainability requires lifecycle supply-chain visibility, resource bookkeeping and revamp planning. The lifecycle starts when the idea of a product is born and lasts until complete disposal after realisation and operation. In the musts' specification/analysis, the crucial policy (global plans, detailed design, assembly plots, etc.) are followed by manufacturing, testing, delivery, diagnostics and operation, advertising, service, maintenance, etc.; then, disassembly and firing are scheduled, requiring reclamation and recovery, via re-cycling (material reprocessing) or re-using (part refurbishing). The present study summarises pilot cues for understanding the product-process agendas, using the TYPUS metrics and the KILT model, prospected by the authors, in previous works

Design and Development of a Landmines Removal Robot

Humanitarian demining is a calamity of war affecting many third world countries. Mines are cheap weapons, built to sustain horrible injuries that target active people with a knock-on effect upon economic growth. The clearing is time consuming and expensive. Clearing is an engineering duty and the humanitarian goal is a technical challenge. Advanced robotics fulfils this task cleanly and reliably on the condition that upgrades and cost are met, meaning that they lose third-world appropriateness. The challenge is to turn local machines and awareness into effective robotic aids, willingly used by the local people, and to enhance the on-going outcomes. The solution to the demining problem shall be a low cost robotic outfit with resort to nearby available resources and competences (e.g., drawn from the local agricultural machinery and know-how). This paper discusses an ongoing project that aims to develop a low-cost robot with intelligent remote-command abilities, as a cheap productivity upgrading, assembled from standard farming devices, through the shared know-how and commitment of locally involved operators. During the study, the authors have developed a low-cost robot capable of removing mines. The robot consists of modified agricultural components including its mobile carrier and the mine effector
