Abstract

In this study we try to explore the concept of Abandonment Analysis in a holistic context. The main focus of the research is on Abandonment Analysis and its relation with Replacement Analysis. The research also analyzes many aspects of Abandonment Analysis and tries to gauge its effect on Replacement Analysis. Finally the research describes various factors which are responsible for Abandonment Analysis and tries to describe the overall effect of Abandonment Analysis on Replacement Analysis.

Abandonment Analysis

According to this joint study, a solar power satellite (SPS) was like a flat-panel, whose dimension was about 5 kilometers by 10 kilometers by 0.5 kilometers, and the diameter of whose transmission antenna was about one kilometer. Each satellite could generate about 5 to 10 GW electric power continuously. The study envisioned that 60 such satellites would be deployed on-orbit, and asserted that reusable space transportation vehicles such as two-stage-to-orbit launchers were necessary to reduce costs to launch materials to low earth orbit.The costs for nonrecurring research and development, including the cost of the first SPS, for procuring a single SPS, and for the maintenance of a single SPS were estimated in 1979 dollars to be $102.4 billion, $11.3 billion and $204.4 million, respectively.As a final verdict, the U.S. National Research Council (NRC) and the then U.S. Congressional Office of Technology Assessment (OTA) concluded that the DOE-NASA concept, while technically feasible, could not be programmatically and economically achievable. However, space solar power concepts were studied in the United States in the 1990s and the 2000s.If launch costs were lowered, access to space could become easier; thereby, spacecraft design-life and reliability requirements might become lesser, and spacecraft development costs could be lowered. If lightweight and small satellites with thin-film or formation-flight technologies applied were realized, satellites with functions similar to bigger ones might be deployed with less launch costs. While a current spacecraft is to become space debris after its mission ends, a future spacecraft might be returned to Earth for reuse, or on-orbit maintenance, repair and improvement might be realized if launch costs could become lower drastically. Service level and ASA are interesting because they give us good operational productivity measures. But those of us who have taken care to research the correlation between service level and customer satisfaction, usually find that there is only a very weak correlation between the two. Some of us have concluded that service level doesn't matter nearly as much as we had anticipated (although we continue to set our company goals using service level).

Abandon rate is the only true metric that can judge, directly, some form ...
