摘要：	The Texas Department of Transportation (TxDOT) owns and maintains an active fleet inventory of over 17,100 units, replacing about ten percent of the fleet annually. Any methodology that can improve the replacement procedures currently used at TxDOT has the potential of savings millions of dollars. This report describes a replacement methodology developed to assist equipment replacement at TxDOT that includes life-cycle cost history as one of the replacement criteria. This new method takes full advantage of the comprehensive TxDOTs Equipment Operating System (EOS) database. It automatically outputs prioritized replacement lists based on ranking the condition of each unit with respect to the condition of all other units within its class. The research objectives were to develop, test and implement a computerized system capable of updating the analysis data sets, processing and comparing the life cycle cost profiles for all equipment units in TxDOTs inventory, supporting equipment replacement decisions with life cycle cost based replacement criteria, and generating reports in tabular and graphical formats in order to simplify the analysis of the results by TxDOT decision makers. This report, the second of the 4941 series, describes the development of this methodology and the framework of the computer program for its implementation. The third report of this series is the software manual.
