Prediction Model Using Probabilistic Neural Network for Serviceability Deterioration of Stormwater Pipes

Circumferential failures in grey cast iron pipes

A stochastic deterioration process for time-dependent reliability analysis

The paper presents a stochastic gamma process model to account for both population (i.e., sampling) and temporal variability associated with a degradation process that typically increases the probability of failure with the aging of a structure. The proposed method is more versatile than the random-variable degradation rate model commonly used in the structural reliability literature. The reaso...

Gas explosion model for grey cast iron pipes in Amsterdam

This thesis concerns grey cast iron gas pipelines in Amsterdam managed by the regional gas and electricity grid operator Liander. Due to brittle nature and aging process of grey cast iron, probability of explosion in this type of pipelines seems to be increasing. A model for the gas explosion probability is proposed. Multiple factors are taken into consideration, including pipe’s age, length, w...

assessment of the efficiency of s.p.g.c refineries using network dea

data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
