This paper describes a new maintenance selection and scheduling approach for bulk transmission equipment that is based on the cumulative long-term risk caused by failure of each piece of equipment. This approach not only accounts for equipment failure probability and equipment damage, as do reliability centered maintenance (RCM) approaches, but it also accounts for the outage consequence in ter...

We study a cement transportation problem with asset-management (equipment selection) for strategic planning scenarios involving multiple forms of transportation and network expansion. A deterministic mixed integer programming approach is difficult due to the underlying capacitated multi-commodity network flow model and the need to consider a time-space network to ensure operational feasibility....

This paper reports the application of an evidential reasoning (ER) approach, to deal with the evaluation of a contractor, from among different fabrication options of aero-engine equipment. This is followed by a review of current evaluation practices, which begins by highlighting their limitations and then goes on to justify the use of an evidential reasoning approach. The evaluation model is di...

The paper draws on the theory of complex networks, puts forward an evolutionary model to solve the evolutionary problem of equipment maintenance support force systems, whose partial information are only known in the reality. Firstly, we abstract equipment maintenance support force systems into complex networks, and then define six network parameters. Secondly, we describe the network evolutiona...

Construction accidents that involve cranes often relate to struck-by incidents, when the crane or its load is in too close contact with personnel, objects, and/or other equipment. In these incidents, limited or poor visibility of resources in the surrounding work space is often the cause of the problem. The result is often the death, serious injury of worker(s), and/or significant collateral da...

Goal. aim video systems, reduce cost time required choose a by developing mathematical models choosing cameras. object research process selecting elements system. subj...

As the capacity of optical transport networks increases, rapid fault identification and localization become increasingly important. These problems are more challenging than in traditional electronic networks because of optical transparency. In a transparent optical network which does not regenerate optical signals, a fault may propagate to various parts of the network from the origin, and multi...

We present a hands-on outdoor activity coupled with classroom discussion to teach students about wildlife habitat selection, the process by which animals choose where to live. By selecting locations or habitats with many benefits (e.g., food, shelter, mates) and few costs (e.g., predators), animals improve their ability to survive and reproduce. Biologists track animal movement using radio tele...

Selecting the incorrect control during the operation of underground bolting and drilling equipment causes serious injuries. Shape coding and the layout of dual control banks are two aspects of control design which require further examination. The aims of this research were: (i) to determine whether arbitrary shape coding was effective in reducing selection error rates in a virtual analogy of ro...
