An integrated ANP and er condition assessment model for sewer pipelines
( International Society for Trenchless Technology , 2015 , Conference Paper)As sewer networks age, the need for their maintenance arises. Simultaneously, inadequate rehabilitation of sewer pipelines might cause catastrophic failures. Thus, municipalities worldwide must have a detailed knowledge ... -
Automated detection of anomalies in sewer closed circuit television videos using proportional data modeling
( International Society for Trenchless Technology , 2016 , Conference Paper)Sewer pipeline condition information is usually collected using closed circuit television (CCTV). Moreover, in order to evaluate the condition of pipeline, data should be processed by a certified operator, which is time ... -
BIM-based facility management models for existing buildings
( Kuwait University , 2021 , Article)Building Information Modeling (BIM) is mainly used for the design and construction of new buildings. However, one of the main challenges facing BIM adoption for existing or old buildings constructed without consideration ... -
Condition assessment of sewer pipelines using multi attribute utility theory (MAUT)
( International Society for Trenchless Technology , 2016 , Conference Paper)Many municipalities rely on the interpretation of Closed Circuit Television (CCTV) inspection reports to arrive to a condition assessment grade for the inspected sewer pipelines. The grades stand as a key for decision ... -
Cost benefit analysis for failure of sewer pipelines
( EDP Sciences , 2017 , Conference Paper)Sewer pipelines failure in sewage networks can have adverse potential impacts on socio-economic aspects in any community. Due to the fact that it's difficult to capture the relationship between the physical and economical ... -
Defect based deterioration model for sewer pipelines using bayesian belief networks
( Canadian Science Publishing , 2017 , Article)A defect based deterioration model to determine the condition ratings in a probabilistic manner for sewer pipelines is presented in this paper. Bayesian belief network (BBN) is used to develop a static model using probabilities ... -
Defect-Based Condition Assessment Model for Sewer Pipelines Using Fuzzy Hierarchical Evidential Reasoning
( American Society of Civil Engineers (ASCE) , 2021 , Article)Assessing the condition of sewer pipelines is essential for addressing associated problems as a result of deterioration to maintain functionality and avoid additional social costs. This paper presents the development of a ... -
Evidential Reasoning–Based Condition Assessment Model for Offshore Gas Pipelines
( American Society of Civil Engineers (ASCE) , 2016 , Article)Condition assessment of oil and gas pipelines is a significant component in pipeline operations and maintenance. Such assessments are used to ensure better decisions for repair and/or replacement to reduce pipelines’ failure ... -
Integrated performance assessment model for water distribution networks
( Taylor and Francis Ltd. , 2016 , Article)The American infrastructure report card in 2013 rated the US water system infrastructure with grade of ‘D’. The Canadian infrastructure report card in 2012 stated that around 15.4% of Canada’s water infrastructure has a ... -
