Fuel consumption of cars and light-duty trucks is one of the most vigorously debated issues in the U.S. While impressive gains have been made in terms of both fuel efficiency and individual vehicle fuel economy in the past two decades, the overall fuel consumption of the U.S. light-duty vehicle fleet continues to grow. Although concerns about the effect of emissions from the vehicles and a significant reliance on imported oil provide legitimate reasons for government action to manage fuel consumption, the economic and societal impacts of such intervention assume multiple dimensions. This research finds that there exists no silver bullet for reducing the fuel consumption of motor vehicles in the U.S. However, there are several different policy measures available to affect the production and purchase of more fuel efficient vehicles as well as reduce the amount of driving. Qualitative and quantitative analysis of individual of policy options reveals the potential for combination of policies. A fleet model helps understand the time delay between the introduction of new fuel efficient vehicles and the reduction in fuel consumption of the fleet. Analysis of political and institutional obstacles enables an evaluation of the feasibility of a comprehensive policy package. A reinforcing combination of different policies can increase the overall effectiveness of the proposed strategy. Such an approach aims at exploiting synergies between different measures...

Manufacturing facilities ramping up a new production process are faced with critical decisions, which determine the ability of that process to be cost efficient. Without quantitative analyses, these decisions are made with limited data and may cause manufacturing problems. Two critical decisions are examined in this research: what level of structured training to provide to employees and what cycle time to run when compared with the long-term optimal cycle time. By examining these decisions and their impact on two production metrics, unplanned equipment downtime and reject rate, a series of analyses are presented. A framework for conducting analyses is developed using Process Based Cost Modeling. This framework is applied to various automobile part manufacturing processes. The results indicate that production experience is critical for reducing the two performance metrics of unplanned downtime and reject rate. Additional analyses indicate that to achieve the best cycle times, a significant investment in structured training should be provided. Analytically determining the optimal cycle time is critical to improving production ramp-up because costs increase when running other cycle times. Future work would apply this framework to other manufacturing processes and gather additional data on the processes examined here.; by Colleen Beth Akehurst.; Thesis (S.M.)--Massachusetts Institute of Technology...

In this dissertation, I trace methods for organizing skilled workers engaged in creative, limited-term projects in the United States between the nineteenth century and the 1950s. Examining eras of system building in technical fields-civil engineering in the nineteenth century, laboratory administration in the 1910s and 1920s, aircraft design in the 1930s, and electronics in the 1950s-I show that recent discourse on the management of innovation and change is a manifestation of a cyclically recurring conversation. This story complicates prevalent views of management theory and practice before World War II by recovering a thread obscured by emphasis on the organization of integrated, divisional companies and operative labor within them. Applying ideas from recent work in organization studies to distill common aspects of the management problems and labor processes individuals have confronted and theorized, I find common patterns: managers of construction firms, engineering departments, and research laboratories have again and again theorized the fast-moving, knowledge-intensive, relational organization, doing so long before these terms were available. Such thinking has been driven both by practical needs and because external pressures have forced explanation of seemingly uncontrolled...
