Increasing numbers of companies in the manufacturing industry have identified market potential for implementing sustainable and green manufacturing. Yet, current sustainability assessment tools for companies are complicated, requiring vast amounts of data and technical expertise to use them. Value Stream Mapping (VSM) is founded on lean practices, and it uses a simple method to analyze various types...
Rapid development in the semiconductor industry requires close collaboration between the design and manufacturing teams in order to increase performance, reduce cost and improve the quality of the electronic products manufactured. The current development process is mainly chip-driven design flow that regards package design as a small add-on. This paper proposes the concurrent design concept of chip...
The goal of the paper is to provide RFID based management methodologies for the production and distribution processes in the life cycle management of home appliances. Major hardware components and software functions of the process management systems are described as a combination case of closed-loop and open-loop applications. For the closed-loop application in factories, HF RFID tray tags, workstation...
The product carbon footprint (PCF) of a mainstream Dell laptop, including raw materials consumption, manufacturing, logistics, product use and end-of-life management was assessed in order to determine environmental “hot spots” across the life cycle. Product bill of material (BOM), supply chain logistics, product energy use and end-of-life scenario data were utilized to model the carbon footprint using...
This paper proposes a PDM design based on the clothing plate-type, and integrates the various different tools and software used in the stages of the product life cycle. So that the data can be used unhindered by the designers, producers, managers and marketers at all stages. It solved the problem that date can only be used in a phase-specific. In this paper, we construct the two three-tier structure...
Material flow analysis (MFA) becomes more and more an important instrument to support environmental protection and sustainable development. Often, a special approach, life-cycle assessment (LCA), is put on the same level with material flow analysis. Based on the industrial ecology or industrial metabolism paradigm (Fischer-Kowalski 1998, Fischer-Kowalski and Hu??ttler 1999), we interpret material...
Along with the rapid development of the computer industry environment, the contradiction between desktop computers and environments is increasingly prominent. The text analyze the whole life cycle of the desktop computer starting from the concept of sustainable development and the basic concept of life cycle. When finish the matrix of life cycle assessment method according to factors which make effect...
Over the past twenty years, environmental issues have gained greater public recognition. The general public has become more aware that the consumption of manufactured products and marketing services, as well as the daily activities of our societies, adversely affect supplies of natural resources and the quality of the environment. These effects occur at all stages of the life cycle of a product, beginning...
Nowadays, manufacturers are facing great challenges with regard to the production of green products due to the emerging issue of hazardous substance management (HSM). In particular, environmental legislation pressures have yielded to increased risk, manufacturing complexity and green components demands. The green principles were expanded to many departments within organization, including supply chain...
The energy consumed to produce and purify a kilogram of laser vaporization SWCNTs at the laboratory scale was found to be 0.13-0.19 GWh/kg under standard production conditions, with 0.114 GWh/kg coming from electrical energy. Most of the energy consumption results from thermal and resistive losses of the laser and single zone furnace in use. The time and temperature of final oxidation of the material...
This paper uses economic value metrics to evaluate the retention of value of secondary materials and provides a framework for characterizing value throughout a material and product life-cycle. These economic value metrics are compared with analogous life cycle assessment metrics in order to determine the conditions under which economic value effectively represents environmental impact for EoL material...
Due to their unique electrical, thermal, and mechanical properties, single wall carbon nanotubes (SWCNTs) have attracted considerable interest for use in a number of applications such as lithium ion batteries, fuel cells, and conductive wiring. However, the energy required to synthesize and purify SWCNTs in the manufacturing phase must be considered in order to fully realize the benefits in the use...
Existing Life Cycle Assessment does not take into account the relative temporal differences in inventory data. The lack of such considerations could lead to an inaccurate analysis of impacts and to incorrect conclusions in the comparative studies of products with comparable inventories but different life cycle times. In this paper, we report on our research of the investigation of the embedded temporal...
To improve manufacturing capability of national defense industry, the paper brings forward cutting tool life-cycle management problem. And then studies its key technology, including cutting tool resource classification and code technology, etc.. Further more, The paper lastly analysis and designs cutting tools life-cycle management system through IDEF methodology and then gives the key page of TLMS...
When it comes to understanding the Cost of Test, we all tend to start philosophizing on the multitude of factors that must go into such an equation. In fact, the Office of the Secretary of Defense, Cost Analysis Improvement Group took over 149 pages to layout all the attributes and assumptions in 1992. This paper explores a different way of approaching the problem. Instead of developing algorithms...
An improved method for the measurement of innovation and innovative activity across long life cycles, especially where patentable technology plays a part in the innovation is studied in this article. In a previous publication we were able to distinguish four stages of a long life cycle. In this article we examine whether the patent life cycle and the production activity life cycle are related. Two...
The work shows a case study where LCA (Life Cycle Assessment) was used as a tool-driven in the development of a Brazilian vehicle, namely a Buggy. It analyzed the environmental advantages to employ vegetal fibers in development products by LCA focus using the software SIMAPRO V7.1 based on stages of vehicle, from raw material extraction to production. The results are presented by means of confrontation...
