INDUSTRIAL ENGINEER – VOLUME 45, NUMBER 3

BY RONALD ASKIN AND THOMAS O. BOUCHER

Researchers from Qatar University (K.N.Al-khalifa, A.M.S. Hamounda and X. Liu) and Rutgres University (j. Li, D. Coit abd E. Elsayed) have been cooperating with leading liquefied natural gas (LNG) processing companies in Qatar with support from Qatar National Research Fund to investigate effective modeling approaches for condition – based maintenance for continuously monitored degrading systems that exhibit multiple failure modes, such as most of the mechanical components of generator and compressors. Since determine the distribution of the time when the degradation reaches the maintenance time. A case in point is the recent recall by General Motor of more than 40,000 cars sold in warm – weather states (Arizona, California, Nevada, Florida and Texas) because a plastic part connected to the fuel pump could crack and cause a fuel leak. This presents a challenge for degradation modeling of pipelines that traverse several countries with different pollution control regulations and climate. Product consistency and repeatability in the face of environmental variations repeatability is one of the most desired features of any engineering product. Insemuconductor manufacturing, lot sizes are often small and high product mixes need to be accommodated.

Conclusion:
They define the problem with researchers from Qatar University (K.N.Al-khalifa, A.M.S. Hamounda and X. Liu) and Rutgres University (j. Li, D. Coit abd E. Elsayed). The problem is that this system has a number of failure modes such as most of the mechanical components of generators and compressors. In this case, maintenance is initiated only when the degradation is a stochastic process and the degradation path varies, it is important to determine the distribution of the time when the degradation path reaches the threshold. More importantly, since units can exhibit sudden failures before degradation reaches the threshold, it is important to consider these situations to provide a realistic estimate of the maintenance time.  This article was included in design for products and sustainability because systems that exhibit multiple failure in the compressor of a generator and mechanical component. That might endanger the user safety as fuel leak. That mistakes make that product become reject product and not fit for use.
