Life Cycle Environmental and Cost Evaluation of Bioenergy Systems
… from a life cycle perspective, environmental and cost implications of near-term bioenergy applications in the transportation and electricity sectors. Key tradeoffs related to the attributes of the systems are elucidated. Three case studies are conducted to consider the site-specific nature of …

Capital cost evaluation of advanced reactor designs under uncertainty and risk
… in global nuclear generation. High capital costs and the risk of overruns and delays may prevent the industry from realizing this new potential. Recent nuclear projects in the U.S. and Europe have averaged cost overruns more than 2x the original estimate. However, new reactor architectures …

A Comprehensive Decision Support System(CDSS) for Optimal Pipe Renewal using Trenchless Technologies
… within a main. The increasing repair and damage costs and degrading services demand that a deteriorating water main be replaced at an optimal time instead of continuing to repair it. In addition, expanding business districts, indirect costs, and interruptions including protected areas, waterways …

Assessing the effect of design for producibility on repairable product life-cycle cost
A life-cycle cost evaluation model is presented to assess the effect of design decisions (made in an attempt to induce higher degrees of producibility) upon a product's life-cycle cost. The model provides a measure of effectiveness in terms of an expected annual equivalent total system life-cycle …

Traffic flow management under emergency conditions in and around the Virginia Tidewater area tunnels
… A microcomputer model called Queue and User Cost Evaluation of Work Zones(QUEWZ) was employed in studying lane closure scenarios for the Virginia Tidewater Area Tunnels. In case of significant capacity reductions or complete blockages of directions of travel, it is desired to know beforehand …

A bi-level system dynamics modeling framework to evaluate costs and benefits of implementing Controller Pilot Data Link Communications and Decision Support Tools in a non-integrated and integrated scenario
A modeling framework to evaluate the costs and benefits of implementation of Controller Pilot Data Link Communication (CPDLC), and Air Traffic Management (ATM) decision support tools is proposed in this paper. The benefit/cost evaluation is carried out for four key alternatives namely alternative …
