In the oil industry, productivity of wells depends on performance sub-surface equipment system. These systems often have problems stemming from sand, corrosion, internal pressure variation, or other factors. order to ensure high and avoid high-cost losses, it is essential identify source possible failures in early stage. However, this requires additional maintenance fees human power. Moreover, ...

In this study the equipment lease contract, where two players, lessor, to user (lessee), if fails exceed tolerance agreed by both players during period and needs be repaired, it is considered detrimental lessee, because results in a loss of potential revenue will received from leased equipment. Therefore, total income lessor contract may incur penalty costs as consequence for failure maintain m...

The rarity of equipment failures results in a high level imbalance between failure data and normal operation data, which makes the effective classification prediction such difficult. Furthermore, many are dominated by mixed model unable to adapt this type problem. Second, replacement cycle production increases difficulty collecting data. In paper, an diagnosis method is proposed solve problem p...

Integrated Intelligent Equipment Health Management System (IIEHMS) is a systematic engineering design Framework that includes multi-functional disciplines (such as mechanical, electrical, optical and software engineering, quality assurance, and manufacturing) with their partners and suppliers works together to achieve a green topology plant with respect to life cycle cost. The proposed structur...

This study explores the role of global and local warming on indoor thermal environments of representative buildings in two warm climate cities in the U.S. (Chicago IL, and Houston TX). It uses downscaled climate change scenarios to drive whole-building model simulations of representative apartment buildings. Simulations were conducted under (a) current conditions; (b) conditions that include a ...
