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 …


Multiple Objective Evolution Strategies Using Data Envelopment Analysis, James V. Lill, Timothy R. Anderson Aug 2015

Multiple Objective Evolution Strategies Using Data Envelopment Analysis, James V. Lill, Timothy R. Anderson

Engineering and Technology Management Faculty Publications and Presentations

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 …


Improving Library Efficiency To Meet Patron's Needs: A Data Envelopment Analysis Benchmarking Model, Michael Clark Aug 2015

Improving Library Efficiency To Meet Patron's Needs: A Data Envelopment Analysis Benchmarking Model, Michael Clark

Engineering and Technology Management Faculty Publications and Presentations

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 …
