“…The probability of occurring accident when a rupture takes action is different for each consequence. This value for jet fire, fireball and explosion is 0.5, 0.3 and 0.2, respectively (Han and Weng 2011). Figure 8 shows individual risk for all of consequences by considering the probability of occurring accidents.…”

“…The quantitative method consists of a probability assessment, a consequence analysis and a risk evaluation. The outcome of this method is individual and societal risk (Han and Weng 2011). Generally, risk is defined as a mathematical function that calculates probability of a pipeline rupture and the magnitude of death .…”

“…A comparison between quantitative and qualitative risk analysis has been done and implemented on small and large urban regions. In the quantitative approach many consequences are considered so the outcome has a high precision and in the qualitative method many reasons of failure considered and it is more effective (Han and Weng 2011). Ma et al focused on a new method of quantitative risk assessment for urban natural gas pipeline networks based on grid difference of pipeline sections (GDPSs).…”

ABSTRACT:Natural gas is considered an important source of energy in the world. By increasing growth of urbanization, urban gas pipelines which transmit natural gas from transmission pipelines to consumers, will become a dense network. The increase in the density of urban pipelines will influence probability of occurring bad accidents in urban areas. These accidents have a catastrophic effect on people and their property. Within the next few years, risk mapping will become an important component in urban planning and management of large cities in order to decrease the probability of accident and to control them. Therefore, it is important to assess risk values and determine their location on urban map using an appropriate method. In the history of risk analysis of urban natural gas pipeline networks, the pipelines has always been considered one by one and their density in urban area has not been considered. The aim of this study is to determine the effect of several pipelines on the risk value of a specific grid point. This paper outlines a quantitative risk assessment method for analysing the risk of urban natural gas pipeline networks. It consists of two main parts: failure rate calculation where the EGIG historical data are used and fatal length calculation that involves calculation of gas release and fatality rate of consequences. We consider jet fire, fireball and explosion for investigating the consequences of gas pipeline failure. The outcome of this method is an individual risk and is shown as a risk map.

“…The fuzzy logic principles are also applicable while evaluating estate houses and engineering constructions for potential hazard (Hao-Tien Liu & Yieh-lin Tsai, 2012;Malinowska, 2011;Rusek, 2009). In water network problems they are mainly used for evaluating damage hazard (Bonvicini et al, 1998;Dong Yuhua & Yu Datao, 2005;Esayed, 2009;Han & Weng, 2011;Markowski & Mannan, 2009;Shahriar et al, 2012;Xingquan Liu et al, 2011). The results of over 30 year research have proved that in many engineering situations application of fuzzy models enables integrate and inference form ambiguity information.…”

The research presented in this paper is basically focused on two objectives. Firstly, the selection of parameters affecting the water supply network damage. The causes of failures were selected from a population of tens of breakdown cases and then classified in view of their importance. Secondly, attention was paid to the selection of the most suitable linguistic model which could be commonly used for selecting factors which generate failures. Finally a Mamdani-based model could be worked out as a system possessing best generalization qualities. This model can create bases for an adaptative decision system which can show the type of water supply-sewage network, depending on continuous surface strains due to the mining activity.

Natural gas pipeline has been regarded as the most cost effective and safest channel of gas transportation and has extraordinary strategic significance for the country. There is a need to control the risks during the operation so as to operate the pipeline safely and smoothly under the complicated business environment. In order to evaluate the risk of natural gas pipeline operation management, this paper proposed an approach to evaluate the risk of natural gas pipeline operation management in intuitionistic fuzzy linguistic environments. Firstly, the evaluation criteria of the risk of natural gas pipeline operation management are established from the strategic risk, market risk, financial risk, operation risk, and legal risk aspects. Then experts are invited to evaluate the risk level and the weight of criteria using the linguistic terms. Rating values with regard to the criteria are in linguistic forms; the linguistic terms are modeled with the intuitionistic fuzzy linguistic model. The linguistic ratings are aggregated as the final results. Finally, the example is given to illustrate the feasibility and practicability of the proposed method.
