This study aims to select optimal maintenance strategy for components of an electric motor of the National Iranian Oil Refining and Distribution Company. In this regard, a method based on revised multi choice goal programming and analytic hierarchy process (AHP) is presented. Since improving the equipment reliability is an important issue, reliability centered maintenance (RCM) strategies are i...

Reliability and availability have long been considered twin system properties that could be enhanced by distribution. Paradoxically, the traditional de nitions of these properties do not recognize the positive impact of recovery|as distinct from simple repair and restart|on reliability, nor the negative e ect of recovery, and of internetworking of clients and servers, on availability. As a resu...

Abstract: This paper proposes a decision model for when to repair a multi-state system from the collective viewpoint of the system designer/engineer as well as the system users (customers). Most systems normally deteriorate stochastically over time, and have several levels of performance. This degradation of performance causes the utility loss for customers and forces them to consider repairing...

Introduction: The patient-centered clinical method allows the biopsychosocial model to be implemented in practice. It is critical look at use of method, which has been shown benefit both patients and clinicians, particularly primary care. Measure Patient-Centered Communication (MPPC) a theory-based instrument for assessment patient-physician interaction. aim this research investigate inter- int...

Radical Maintenance (RM) takes the root causes of failures as executive objects to make maintenance decisions. A Root Cause Analysis (RCA) is carried out on the function failure of equipment to performRMand to create a maintenance plan using the combined methods of Failure Mode, Effects and Criticality Analysis (FMECA), and Fault Tree Analysis (FTA). Evaluation criteria andmatrixes of criticali...
