• A state of the art review on condition assessment models developed for sewer pipelines 

      Hawari, Alaa; Alkadour, Firas; Elmasry, Mohamed; Zayed, Tarek ( Elsevier , 2020 , Article)
      In order to achieve an efficient and a successful operation and maintenance plan for assets, management personnel should have detailed information on the condition of the assets to make informed strategic decisions and ...
    • Cost benefit analysis for failure of sewer pipelines 

      Elmasry, Mohamed; Hawari, Alaa; Zayed, Tarek ( 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 

      Elmasry, Mohamed; Hawari, Alaa; Zayed, Tarek ( 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 ...
    • Discrete event simulation for sustainable batch production in food processing 

      Elmasry, Mohamed; Tarek, Fatma ( Dime University of Genoa , 2016 , Conference Paper)
      In a world faced with depleting resources and hazardous biodegradable food wastes, an efficient planning for the food processing operation is crucial to avoid the adverse potential impact of excess food production. This ...
    • Sewer Inspection Prioritization Using a Defect-Based Bayesian Belief Network Model 

      Elmasry,Mohamed; Zayed, Tarek; Hawari, Alaa ( American Society of Civil Engineers (ASCE) , 2016 , Conference Paper)
      In order to successfully implement an asset management program, an accurate and reliable deterioration model for assets should be available. Deterioration models are considered as the basis for predicting and prioritizing ...
    • Simulation-Based Condition Assessment Model for Sewer Pipelines 

      Hawari, Alaa; Alkadour, Firas; Elmasry, Mohamed; Zayed, Tarek ( American Society of Civil Engineers (ASCE) , 2017 , Article)
      Condition assessment models are considered as an evaluation tool that can be used by decision makers to accurately evaluate and assess the condition of pipes. Condition assessment of pipes helps in reaching better decisions ...
