In the paper, a PESTLE (political, economic, social, technical, legal, and environmental) analysis is used to conduct an initial evaluation for electric vehicles (EV) and gasoline cars. Furthermore, two cash flow models are created to describe the scenarios of both gasoline and electric car respectively. Based upon the proposed models, the equivalent uniform annual cost (EUAC) methodology is used to calculate the cost during the period of car ownership. Four compact EVs and five compact gasoline cars are selected in the analysis. The results expose that the actual return of federal tax credit impacts the EUAC value. The 50% return …

Technological innovation and the information age have increased patrons’ expectations of the services and resources that academic libraries provide. Libraries are responding to patrons’ needs by providing digital resources and services, and collaborative spaces that invite communication and knowledge sharing. In order to effectively meet patrons’ needs, libraries are striving to efficiently manage their human, materials, and fiscal resources. Libraries have traditionally measured efficiency by developing single factor productivity indexes. However, these qualitative methods do not adequately address the efficiency aspect which measures the transformation of resources (inputs) into services (outputs). Data envelopment analysis (DEA) measures the relative efficiencies of …
Multiple Objective Evolution Strategies Using Data Envelopment Analysis, James V. Lill, Timothy R. Anderson
Multiple Objective Evolution Strategies Using Data Envelopment Analysis, James V. Lill, Timothy R. Anderson

Often in science and engineering we are faced with complicated nonlinear problems in optimization that involve simultaneously minimizing or maximizing various non-commensurate quantities. For example, a basic task in design engineering or technology management is to balance suitable measures of performance against the cost. We present a simplified approach for performing multiple objective optimization by combining standard single objective Evolution Strategies with Data Envelopment Analysis. This latter method employs linear programming to compute an L1 distance of a given solution from the Pareto frontier defined by the evolving population of solutions, or from a related frontier defined by DEA. This …

The Toyota Prius was first introduced in 1997 and since then over 150 hybrid electric vehicles (HEVs) have been brought to the automobile market around the world. This was spurred by a major interest in the future of vehicles using ‘alternative fuel’ for addressing environmental and fuel dependency concerns. Based upon previous work1, which identified an input-output model that could successfully explain the progress of HEV technologies, this study evaluates and compares the technological advancement observed in different HEV market segments over the past 15 years. The results indicate that the introduction of a wide range of midsize HEVs is …
