One important issue in using the industrial and manufacturing facilities is to consider their impacts on the environment. Many of these equipment have negative effects on the environment when operated for sometimes. In this research the probabilistic logistic times and the destructive effects for maintenance are studied and appropriate model is suggested and evaluated. The aim of the proposed m...

In general, handling centrifuges is a safe process, as long as high quality equipment is used, such as anodized or PTFE coated aluminum rotors for instance, and the following conditions are met: the centrifuges and their equipment are used properly, are in an undamaged condition and maintained as recommended here. Prevention from long-term exposure to residues like salts or aggressive chemicals...

After 1994, highway bridges are maintained under the Special Law on Structure Safety in Korea. To keep a structure good condition, inspection of the structure has to be performed periodically. The inspection is hard work and needs a lot of time and many inspectors to inspect the structure that is important or damaged. Generally, This contains subjectivity of inspector, and so the result of insp...

As the core part of power grid, substation must carry out regular patrol inspection to ensure normal operation equipment. In recent years, with continuous increase load, area has gradually expanded, which makes its operating environment more complex, intensity increased, and manual method cannot meet needs inspection. Therefore, it is necessary introduce high-tech equipment use robots conduct i...

No matter how well they are designed, all civil engineering structures will deteriorate over time and a program of lifetime inspection, maintenance and repair represents a substantial portion of the total lifetime cost of most structures. An optimized inspection program is the key to making appropriate repairs at the right time to minimize cost and maintain an appropriate level of safety in a s...
