Sensitivity analysis is the study of how the uncertainty in the output of a mathematical model or system (numerical or otherwise) can be divided and allocated to different sources of uncertainty in its inputs. [1] [2] This involves estimating sensitivity indices that quantify the influence of an input or group of inputs on the output.
Analysis of Competing Hypotheses (ACH) is an open-source ACH implementation. [22] ACH Template [23] is an Excel sheet that implements the scoring and weighting methodology of ACH, more specifically the weighted inconsistency counting algorithm.
Sources for failure rate and failure mode data; Fault detection coverage that system built-in test will realize; Whether the analysis will be functional or piece-part; Criteria to be considered (mission abort, safety, maintenance, etc.) System for uniquely identifying parts or functions; Severity category definitions
Failure mode and effects analysis (FMEA; often written with "failure modes" in plural) is the process of reviewing as many components, assemblies, and subsystems as possible to identify potential failure modes in a system and their causes and effects. For each component, the failure modes and their resulting effects on the rest of the system ...
[24] [25] Examples of initiatives made by NIOSH to prevent the negative effects of noise exposure include the Buy Quiet program, which encourages employers to purchase machinery that produces lower noise levels, and the Safe-In-Sound Award, which was created to recognize organizations that excel in noise control.
An insurance company conducted several studies on the effects of stress prevention programs in hospital settings. Program activities included (1) employee and management education on job stress, (2) changes in hospital policies and procedures to reduce organizational sources of stress, and (3) the establishment of employee assistance programs.
The diathesis-stress model, also known as the vulnerability–stress model, is a psychological theory that attempts to explain a disorder, or its trajectory, as the result of an interaction between a predispositional vulnerability, the diathesis, and stress caused by life experiences.
The Perceived Stress Scale was developed to measure the degree to which situations in one’s life are appraised as stressful. Psychological stress has been defined as the extent to which persons perceive (appraise) that their demands exceed their ability to cope .
