Added demands on natural resources and proposed environmental regulations could potentially have a significant impact on the production and operational costs of information technology (IT). In this paper, we utilize an Economic Input-Output Life-Cycle Assessment (EIO-LCA) framework to model projected changes in the cost structure of a portfolio of IT products due to increased electricity prices...

daniels, porteny and urrutia et al make a good case for the idea that that public decisions ought to be made not only “in the light of” evidence but also “on the basis of” budget impact, financial protection and equity. health technology assessment (hta) should, they say, be accordingly expanded to consider matters additional to safety and cost-effectiveness. they also complain that most hta re...

the index is excellent by the malmquist index as extended to productivity measurement. the index developed here is defined in terms of input cost rather than input quantity distance functions in supply chain. therefore, we propose productivity change is decomposed into overall efficiency and cost technical change. these decompositions provide a clearer situation of the root sources of supply ch...

Statistically constrained economic design for profiles usually refers to the selection of some parameters such as the sample size, sampling interval, smoothing constant, and control limit for minimizing the total implementation cost while the designed profiles demonstrate a proper statistical performance. In this paper, the Lorenzen-Vance function is first used to model the implementation...
