Abstract: The objective of this project is to develop a Network Level Management System for the maintenance and rehabilitation of the US Army Corps of Engineers civil works. The Management System is based on a life-cycle analysis of the performance and costs of facilities through some analysis period, as affected by REMR policy. The implementation of life-cycle analyses of facilities requires a new approach to looking at facility performance and the factors which influence costs throughout its service life. This approach is referred to as "demand responsive" in that maintenance and rehabilitation are viewed as responses to the demand for repair or renewal of the facility. Treating REMR actions as demand-responsive activities requires that three additional elements be introduced within existing planning and management models: (A.) Estimates of future resource requirements and costs of managing facilities based on predictions of structural and operational deficiencies caused by use, environment, and age. (B.) Clear statements of REMR policies themselves, defining the types of preventive or corrective actions to be taken, and when and where they are to commence. (C.) Relationships between the as-maintained state of the civil facility, and the impacts on both the Corps and the users of the facility (in terms of preservation of facility investment, the costs, time, and reliability of transportation service provided, safety, etc.), providing a measure of the benefits (or disbenefits) of each policy at the costs computed above. This report explains the concepts involved in applying life-cycle costing to analyses of REMR policies. Considering locks specifically, it then develops example models of facility performance for lock gates, walls, and mechanical equipment, relates this performance to the costs and the impacts of different REMR policies, and builds these models within a prototype version of a microcomputer-based REMR Management System. The prototype system is then applied to several examples to demonstrate the application of demand responsive maintenance concepts to realistic problems, to illustrate the system features and procedures, and to explain the results and their interpretation.
