Background: The reliability and safety of gas refineries are strongly associated with the reliability of other parts of the system. Defect and failure in one part of a system can cause total system breakdown or accident. The failure and damage in these equipment such as transformers and boilers results in not only the equipment damage and human injuries but also productivity reduction. The purp...

OBJECTIVE To investigate the nature of process failures in postoperative care, to assess their frequency and preventability, and to explore their relationship to adverse events. BACKGROUND Adverse events are common and are frequently caused by failures in the process of care. These processes are often evaluated independently using clinical audit. There is little understanding of process failu...

This paper examines lessons from the operating experience in India’s nuclear facilities about factors influencing the risk of potential accidents. Different perspectives on safety in hazardous facilities have identified organizational factors coincident with reliable and accident-free operations; these include functional redundancy and compensation for failures, the importance of organizational...

Expected lifetime and reliability of multilayer ceramic actuators were considered. 5 · 5 · 5 mm sized multilayer ceramic actuators with 60 ceramic sheet layers embedded internal electrodes were selected in this experimental analysis. Specially selected rectified AC bias was applied to the multilayer ceramic actuators to remove heating during charging and discharging process. Sixteen sets of mul...

One of the ultimate targets of lean manufacturing paradigm is to balance production and produce at takt time in production cells. This paper investigates the performance of a lean cell that implements the previous lean goals under uncertainty. The investigation is based on a system dynamics approach to model a dynamic lean cell. Backlog is used as a performance metric that reflects the cell’s r...
