Abstract The paper presents a developed computational model based on decision- random models, which allows us to develop strategy for preventive renewal of complex technical objects whose maintenance activities cover various actions. Depending the type, diversification cost and time may influence interval at should be performed. algorithm takes into account predicted proper operation probabilit...
Background & Objectives: Maintenance is an important tool for the petrochemical industries to prevent of accidents and increase operational and process safety success. The purpose of this study was to identify the possible causes of incidents caused by human error in the petrochemical maintenance activities by using Human Factors Analysis and Classification System (HFACS). Methods: This stud...
many serious accidents have happened in the world, in which systems have been large-scale and complex, and caused heavy damage and a social sense of instability. furthermore, advanced nations have almost finished public infrastructure and rushed into a maintenance period. since maintenance is more important than production and construction, then more maintenance for environmental considerations...
With the emergence of predictive maintenance in 1980, radical changes took place in maintenance planning. Predictive maintenance depends on the prediction of facilities failure which are used at present. By predicting the failures correctly in future, we can decrease the cost of maintenance to a great extent. This approach involves using multiple techniques including artificial intelligence, ...
Nowadays, the internet and social networks become more popular than ever. People in all ages use the internet and communicate by that. One of the most terrible events in our daily life is to disconnect from the internet and lose the connections. It may also influence on the economics; so the sustainability in this area is necessary. Internet service provider companies are the executors of selli...
