Weak Site

A component with multiple weak sites is widely used in practical engineering and the existence of multiple weak sites can significantly decrease the component reliability. On the other hand, only a few components bear static loading and most components bear dynamic loading. In this paper, a reliability model of isomorphic component with multiple weak sites is built based on an order statistics model and the influences of strength decentrality and loading decentrality on isomorphic component with multiple weak sites are discussed. Furthermore the influence of loading times is studied in detail. The results show that unlike a component with only one weak site, not only does the failure of a component with multiple weak sites have a relationship with the safety margin, but there also exist relationships with the number of weak sites, the loading roughness, and loading times. The work in this paper is of some guiding significance in reliability design and assessment of a component with multiple weak sites under complex loading.

Smart Distribution Network

Electric power should deliver a predicable per condition for the technological, economic, and political development of any countries and it is vital for each individual. Power outage is series problem in Ethiopia at the hole of distribution network. This is due to frequent interruptions and much time service restoration. That is why most customers of Ethiopia have their day-to-day activities highly affected and they are strongly complaining to Ethiopia electric utility daily. But this power outage affected customer cost and the Ethiopian utility. In most developing countries including Ethiopia, distribution systems have received considerably less of the attention to reliability modeling and evaluation than have generating and transmitting systems. Life is directly or indirectly dependent on electric power so a utility should deliver reliable power every day for 24 hours and each year for 8,760 hours to satisfy human needs and to perform their works as much as possible with less economy.

Planning Decisions

Throughout the developed world the problem of how best to manage aging assets is being faced. It is particularly critical in distribution systems such as mains water reticulation, sewage networks and electricity supply lines. In many towns, some underground water and sewer pipelines are more than 50 years old. It is already prohibitive on cost grounds to replace all these deteriorating assets, so a cost-effective replacement/repair strategy must be used. Reliability modeling-based solutions to this problem are discussed, together with issues related to the quality of the available data. Some of the outcomes for industry are improved monitoring and record keeping, objective evaluation of alternative management options, and reliability prediction to enable sound planning decisions to be made. The applicability of these methods to other distribution systems is also discussed.
