قابليت اطمينان چيست، مهندس اطمينان كيست؟

What is the reliability engineering and who is a reliability engineer?

ما در اين مقاله، براي اولين بار، مي خواهيم به بررسي چيستي قابليت اطمينان و نيز كيستي مهندسين اطمينان با نگرشي جديد بپردازيم. درواقع، اين بررسي بدنبال پاسخ به چند سوال زير است: 1)آيا قابليت اطمينان مفهومي رشته-محور است يعني به رشته تخصصي خاصي مانند برق، مكانيك، صنايع و سازه بستگي دارد؟ 2)آيا قابليت اطمينان مفهومي تجهيز-محور است يعني به نوع دستگاه مورد بررسي بستگي دارد؟ 3)آيا قابليت اطمينان مفهومي متعلق به ماشين است (چه بصورت سخت افزاري و يا نرم افزاري) يا براي سيستم هاي انسان-ماشين و نيز انساني هم قابل محاسبه است؟ 4)آيا قابليت اطمينان مفهومي متعلق به فاز طراحي و ساخت سيستم هااست يا به فاز بهره برداري و نگهداري و تعميرات مربوط مي شود؟ 5) آيا براي درك بهتر مهندسي قابليت اطمينان مي توان آن را به دو بخش مهندسي نرم و مهندسي سخت تقسيم كرد؟

In this paper, we attempt to investigate the concept of reliability engineering and who could be entitled as a reliability engineer from a novel perspective. In fact, we address the following questions: 1) Is there a universal definition for the reliability engineering or in fact we are facing a domain specific concept, i.e. different in fields of power engineering, mechanical, etc.? 2) Should we define the reliability engineering as a concept which is dependent upon the type of component, equipment, or system? 3) Is the reliability of a hardware based system different from a software based system? What about human-machine systems manifested in organization or human body reliability? All are covered? 4) Is reliability a concept belongs to the different phases of design, manufacturing, operations, maintenance? 5) Could be classify the reliability engineering into the soft and hard engineering? These are the types of questions that we are addressing, for the time, in this paper aiming to help to come up with a more universal concepts and techniques in reliability engineering domain.
