A Mechanistic Analysis Based Decision Support System for Scheduling Optimal Pipeline Replacement
Failure of pipes in water distribution systems is a common occurrence especially in large cities. The failure of a pipe results in: loss of water; property damage; interruption of service; decreased system performance; and the financial cost of restoring the failed pipe. The cost of replacement and …

Partially Observable Markov Process Decision Modeling for the Optimal Maintenance of Oil and Gas Pipelines
… of POMDP for maintaining oil and gas pipelines. Pipeline maintenance operations comprise several uncertain elements, especially when addressing deteriorations caused by corrosion. These include the deterioration rate, the effectiveness of maintenance operations, and the accuracy of …
