In order to fulfill all challenges related to design, management, evaluation and reconfiguration of new or existing facilities, the development of a new, integrated and holistic factory framework is required. In this context, a new requirements model is proposed in the context of the innovative framework called Virtual Factory Framework. Using this approach in factory planning it is expected to...

We propose a life cycle optimization framework for the design of sustainable product systems and supply chains considering the concept of “functional unit” under economic and environmental criteria. This general modeling framework integrates the life cycle analysis methodology with multiobjective optimization and measures both the economic and environmental performances based on a standard quan...

life cycle assessment (lca) is one of the decision support systems which can be considered for assessing the different approaches of waste management. however, it only considers environmental effects and ignores other decision making options such as economic and social effects of solid waste management. in this research, we consider a combination of three decision making options including en...

effect of five soybean varieties (sahar, jk, bp, williams and l17) on life cycle and fecundity of the beet armyworm, spodoptera exigua (hã¼bner) was evaluated at temperature of 25 â± 1â°c, 60 â± 5% r.h. and a photoperiod of 16: 8 (l: d) h. the preimaginal development period of males and females was longest on l17 (30.17 â± 0.28 and 29.63 â± 0.23 days) and shortest on bp and sahar. the adult lon...

This article describes a framework for managing the life cycle of knowledge in organizations. The framework emerges from years of work with the laboratories and facilities that are under the direction of the United States Department of Energy (DOE). The article begins by describing the background of the work from which the framework emerged; this is followed by describing the problem of identif...

This Article presents the analysis– of the Zachman Framework for enterprise Architecture and its mapping onto the Generalised Enterprise Reference Architecture and Methodology (GERAM) framework / ISO IS15704:2000 requirements. Aspects covered concern the ability of the Zachman Framework to cover the complete scope of the GERAM meta-mode, such as life cycle / life history concepts, modelling fra...

The life-cycle model is a standard theoretical framework for studying savings and wealth inequality. This paper shows that life-cycle models have di¢ culties accounting for the empirical relationship between lifetime earnings and household wealth. Quantitative life-cycle models imply a far tighter relationship between earnings and wealth than is observed in U.S. data. As a result, life-cycle mo...

escalating development of tourism and petroleum industries in small islands such as lavan-iranrequires sound solid waste management. in the present investigation, three scenarios which consist of thecombination of landfill, recycling, incineration and composting and their environmental impacts have beenevaluated for 7514 kg/day of waste generation in lavan island. for this purpose, life cycle a...

in this study a pseudo comprehensive carbon footprint model for fossil fuel power plants is presented. parameters which their effects are considered in this study include: plant type, fuel type, fuel transmission type, internal consumption of the plant, degradation, site ambient condition, transmission and distribution losses. investigating internal consumption, degradation and site ambient con...
