An optimization model for maintenance of engineering structures

With the recognition that the engineering structures maintenance and repair needs far exceed the resources available to address these needs, many firms have turned to the development of ESMS (engineering structures management system) as a method to improve the allocation of these limited resources and the condition of their engineering structures. The paper provides an overview of the need for ESMS. The concepts of level-of-service goals for functional adequacy, deterioration modeling and the relation of structural adequacy and optimization strategies for resource allocation.
