tailieunhanh - Handbook of Reliability, Availability, Maintainability and Safety in Engineering Design - Part 61

Handbook of Reliability, Availability, Maintainability and Safety in Engineering Design - Part 61 studies the combination of various methods of designing for reliability, availability, maintainability and safety, as well as the latest techniques in probability and possibility modelling, mathematical algorithmic modelling, evolutionary algorithmic modelling, symbolic logic modelling, artificial intelligence modelling, and object-oriented computer modelling, in a logically structured approach to determining the integrity of engineering design. . | 584 5 Safety and Risk in Engineering Design - the estimated reportable hazard frequency arising from functional failure of the item - the estimated physical condition of the item related to its safety. The actual degree of safety. This is measured according to the contribution of - the actual disabling injury frequency arising from functional failure of the item - the actual reportable hazard frequency arising from functional failure of the item - the actual physical condition of the item related to its safety. The assessment of estimated disabling injury frequency considers severity criteria such as Life risk when the occurrence of critical functional failures can be expected to result in a risk of loss of life every time. Loss risk when the occurrence of critical functional failures can be expected to result in a risk of loss of limb every time. Health risk when the occurrence of critical functional failures is expected to result in the risk of a health hazard every time. The assessment of estimated reportable hazard frequency considers severity criteria such as People risk when the occurrence of critical functional failures can be expected to result in the risk of an accident affecting people working in the area every time. Environment risk when the occurrence of critical functional failures can be expected to result in the risk of an accident affecting the environment every time. Process risk when the occurrence of critical functional failures can be expected to result in the risk of an accident affecting the production process every time. Product risk when the occurrence of critical functional failures can be expected to result in the risk of an accident affecting the related product every time. The assessment of estimated physical condition considers severity criteria such as Loss risk when the item s physical condition can be expected to result in process losses in the system that will result in critical functional failures becoming imminent.
