A Model for Interoperable Performance Assessment: for Infrastructure Evaluation

Canadian infrastructure is deteriorating at an alarming rate, and accruing an expensivebill in rehabilitation expenses. Various infrastructure systems are attempting to assessperformance in order to allocate resources accordingly. However, there is a lack ofinteroperable means for sharing information about infrastructure performance. Thisresearch presents a concept for a generic and comprehensive performance assessmentmodel that may be applied to infrastructure systems in order to assess performance andidentify needs more precisely in an interoperable fashion. The model focuses ontransportation, water, wastewater and power supply systems. Five main unifiedperformance measures were selected for the systems and served as categories for thevarious performance indicators. The model was improved through input from domainexperts. An XML schema was developed for the model, which will promote systeminteroperability and enhance system compatibility. An interactive user interface wasdeveloped to support the education of the model users.
