For the safety of coal production, base on fundamental principle of Fuzzy-AHP comprehensive evaluation method, taking all influencing factors of coal mine safety into consideration, index system of safety evaluation was given, weights of mine safety estimation factor were determined using the Analytical Hierarchy Process, the evaluation model was set based on Fuzzy-AHP comprehensive evaluation method,...
With the increasing complexity in civil engineering projects, the multi-program group has become a large-scale system problem. Three analysis models for safety evaluation are discussed in this paper: safety comprehensive analysis model, safety performance analysis model and safety contribution-rate model. Then the safety indexes of these models are deduced and build up respectively. Furthermore, the...
Due to the serious condition of safety production in hydropower construction project on the whole, it is an urgent need to evaluate hydropower engineering construction safety. But the problem of the mapping relationship between evaluation index and accidents, fixed and variable weight, randomness and fuzziness and so on, can't be solved through the traditional safety evaluation method for hydraulic...
The construction is the high risk profession so that the security situation is unoptimistic. The safety evaluation technology can raise the enterprise's safety control level, causing the safety control transferring from the prevention transformation to the self-contained guidance, which sharpened the enterprise against the accident's ability enormously. Therefore, this article analyzed the evaluation...
Coal mine safety evaluation analyses mine's existent dangerous and harmful factors, and judges mine's potential risks. The evaluation result is propitious to guard against accidents and make management decisions. This paper analyses all kinds of influence elements on coal mine safety, constructs evaluation indexes system, measures weights using AHP, and applies dynamic fuzzy theory in mine safety...
Hazard is evaluated for electrical design of a major system upgrade of Thailand oil & gas production plant. The primary technique for the hazard evaluation was a hazard and operability (HAZOP) study; this is a brainstorming approach conducted by a multidisciplinary team. The approach simulates creativity of the team members to generate new ideas. As a result of this study, numerous, qualitative...
