Selected AbstractsImplementing life cycle assessment in product developmentENVIRONMENTAL PROGRESS & SUSTAINABLE ENERGY, Issue 4 2003Gurbakhash Singh Bhander The overall aim of this paper is to provide an understanding of the environmental issues involved in the early stages of product development, and the capacity of Life Cycle Assessment (LCA) techniques to address these issues. The paper aims to outline the problems for the designer in evaluating the environmental benignity of a product from the outset, and to provide a framework for decision support based on the performance evaluation at different stages of the design process. The barriers that prevent product developers from using LCA are presented, as well as opportunities for introducing environmental criteria in the design process by meeting the designer's information requirements at the different life cycle stages. This can lead to an in-depth understanding of the attitudes of product developers towards the subject area, and an understanding of possible future directions for product development. This paper introduces an Environmentally Conscious Design method, and presents trade-offs between design degrees of freedom and environmental solutions. Life cycle design frameworks and strategies are also addressed. The paper collects experiences and ideas around the state-of-the-art in eco-design, from literature and personal experience, and provides eco-design life cycle assessment strategies. The end result of this presentation is to define the requirements for performance measurement techniques, and the environment needed to support life cycle evaluation throughout the evaluation of early stages of a product system. [source] Product Technology Transfer in the Upstream Supply ChainTHE JOURNAL OF PRODUCT INNOVATION MANAGEMENT, Issue 6 2003Mohan V. Tatikonda This article addresses the transfer of new product technologies from outside the firm for integration into a new product system as part of a product development effort. Product technology transfer is a key activity in the complex process of new product development and is the fundamental link in the technology supply chain. Product technology transfer too often is dealt with in an ad-hoc fashion. Purposeful management of the product technology transfer process leads to more effective transfers in terms of timeliness, cost, functional performance, and competence building. Better management of product technology transfer gives firms access to a greater variety of new technology options, improves a firm's ability to offer significantly differentiated products, deepens the firm's competitive competencies, and positively influences sustained product development success. The central objective of this article is to gain insight into product technology transfer so that companies can manage this process more successfully and so that researchers can investigate this critical activity further. This article describes the technology supply chain as a unique form of a supply chain that poses a set of managerial challenges and requirements distinguishing it from the more traditional component supply chain. Because a single product technology transfer project is the fundamental piece in the technology supply chain, understanding this piece well is key to leveraging the extended technology supply chain and to improving overall product development performance. This article integrates literatures on new product development, supply chain management, and technology management and builds on organizational theory to present a conceptual model of determinants of product technology transfer success. The core proposition is that product technology transfer effectiveness is greatest when companies carefully match (or "fit") the type of technology to be transferred (the "technology uncertainty") with the type of relationship between the technology supplier and recipient (the "interorganizational interaction"). A quite detailed framework characterizing technology uncertainty along the dimensions of technology novelty, complexity, and tacitness is presented to help in assessing the challenges associated with transferring a particular product technology. This article also considers detailed elements characterizing the interorganizational interactions between the technology source and recipient firms. This helps firms consider the appropriate means to facilitate the interfirm process of technology transfer. Overall, this article provides practical insight into characterizing technologies and into improving the product technology transfer process. This article also provides a strong theoretical foundation to aid future research on product technology transfer in the technology supply chain. [source] Characterizing, Propagating, and Analyzing Uncertainty in Life-Cycle Assessment: A Survey of Quantitative ApproachesJOURNAL OF INDUSTRIAL ECOLOGY, Issue 1 2007Shannon M. Lloyd Summary Life-cycle assessment (LCA) practitioners build models to quantify resource consumption, environmental releases, and potential environmental and human health impacts of product systems. Most often, practitioners define a model structure, assign a single value to each parameter, and build deterministic models to approximate environmental outcomes. This approach fails to capture the variability and uncertainty inherent in LCA. To make good decisions, decision makers need to understand the uncertainty in and divergence between LCA outcomes for different product systems. Several approaches for conducting LCA under uncertainty have been proposed and implemented. For example, Monte Carlo simulation and fuzzy set theory have been applied in a limited number of LCA studies. These approaches are well understood and are generally accepted in quantitative decision analysis. But they do not guarantee reliable outcomes. A survey of approaches used to incorporate quantitative uncertainty analysis into LCA is presented. The suitability of each approach for providing reliable outcomes and enabling better decisions is discussed. Approaches that may lead to overconfident or unreliable results are discussed and guidance for improving uncertainty analysis in LCA is provided. [source] Measurement and analysis of ,small' packages in next-day air shipmentsPACKAGING TECHNOLOGY AND SCIENCE, Issue 1 2010S. P. Singh Abstract Packaged goods are shipped globally using various means of transportation. Over the past two decades, there has been a continuous increase in studies that measure and analyse dynamic events that occur to packages during transportation and handling. These data offer useful information to design and test packages, and provide protection from potential hazards like drops and impacts. However, none of the past studies are directed towards single packages regarded as ,smalls'. ,Smalls' or small-package product systems are defined as those with volume of less than 0.013,m3, a longest dimension of 0.356,m and a weight of 4.54,kg or less. Packages that qualify for these specifications are often mixed together in a large carrying bag and handled with other single parcel shipments. This study measured and analysed the effect of moving this category of single packages through expedited shipments in the USA. The results showed that these packages experienced as many as 27 events comprising of drops or tosses in a one-way shipment, and a maximum of 5.01,m of near-zero G travel distance representing long ,tosses'.
