A systems approach to improving fleet policy compliance within the US Federal Government

Refueling Behavior of Flexible Fuel Vehicle Drivers in the Federal Fleet

“…These findings are consistent with findings from Nicholas (2010) and Kitamura and Sperling (1987) that most drivers want to fuel near a trip's origin, frequently refuel on commuting routes, do not necessarily refuel close to home, and have a low distance/time threshold to deviate from those paths. These findings contradict the methodology used to determine "access to alternative fuel" based on a garage location (Helwig and Deason 2007;and Deason and Jefferson 2010; DOE 2011)-which serves as a proxy for "home" when driving a work vehicle.…”

“…An extensive body of academic literature has dealt with various aspects of EPAct and related federal statutes, while only a few have focused specifically on implementation of these requirements within the federal fleet. Helwig and Deason (2007), and Deason and Jefferson (2010) focused their attention on the suboptimal vehicle acquisition strategies that left many federal FFVs without access to alternative fuel. Their basic premise is that smarter placement of FFVs, near existing alternative fuel infrastructure, will lead to significant improvements in alternative fuel consumption.…”

Optimizing Federal Fleet Vehicle Acquisitions: An Eleven-Agency FY 2012 Analysis

“…Using the NREL Optimal Vehicle Acquisition (NOVA) analysis, the study produced specific, individual vehicle recommendations determined by integer optimization models for each agency, in consideration of the wide array of competing acquisition requirements for these fleets. Development and use of the NOVA analysis expands on previous work by Helwig and Deason (2007) and Deason and Jefferson (2010).…”

Applying the Analytic Hierarchy Process to Oil Sands Environmental Compliance Risk Management

“…Therefore, the quantitative ranking of environmental risks and mitigation strategies ruled out the potential lack of trustworthiness and rigor of a qualitative design (Schwandt, Lincoln, & Guba, 2007). AHP was especially appropriate for the research design because it is often used in the study of risk management and decision-making processes (Briggs, 2010;Deason & Jefferson 2010;Varma, Wadhwa, & Deshmukh, 2008). For example, environmentalists use AHP for environmental sustainability assessments and environmental decisionmaking (Kara & Köne, 2013;Steele, Carmel, Cross, & Wilcox, 2009;Tegou, Polatidis, & Haralambopoulos, 2010).…”
