Quantitative approaches to physical ergonomic issues encountered while assessing workplace designs

摘要: Ergonomic and design practitioners routinely make assessments of the appropriateness a workspace. For example, must answer questions such as: “will user be at risk injury, is space high enough, wide enough deep to accommodate intended users, does facilitate performance”? Such include examination characteristics both work that performed users’ capabilities preferences in order conclusions regarding safety facilitation performance. The nature these varies. They may subjective; as an practitioner feel requires too much repetitive motion or small all users. based on tools appear quantitative, for checklists related musculoskeletal disorders, reference tables anthropometric percentile data reviews appropriate technical literature. All assessment methds require conclusion design; however, quantitative basis often unknown unreliable. predictive validity checklist not known limited force combine percentiles by addition subtraction, practice lead error. In this dissertation, methods suitable use are developed address issues. A method dynamically calculating introduced, more accurately combining when only available. Finally determining performance analogous “fitting trial” used quantitatively resolve situation where previous research suggests contradictory criteria.
