Abstract: Embodiments provide functionality to assess dynamic ergonomic risk. One such example embodiment receives process planning data for an operator performing a task. Based on the received process planning data, parameters for a time analysis are defined and a time analysis of the operator performing the task is performed using the defined parameters. In turn, static ergonomic risk is determined based on the received process planning data. Then, an indication of dynamic ergonomic risk is provided based on (i) results of performing the time analysis and (ii) the determined static ergonomic risk.

Abstract: Embodiments assess ergonomic risk of causing harm to a worker in a workplace. One such embodiment receives an indication of posture risk level for each of a plurality of digital human models performing a task. In turn, a weighted average of the received indications of posture risk level is determined. This determined weighted average is indicative of ergonomic risk to a real-world worker performing the task in a workplace. Embodiments consider consecutive risk through modifications to weights used in the determining the weighted average.

Abstract: Embodiments assess ergonomic risk in environments, such as factories and workstations. One such embodiment begins by receiving process planning data for an operator performing a task. In turn, the received process planning data is used to generate a posture for the operator to perform the task in a certain real-world environment. The generated posture is processed using a hierarchical decision tree to determine ergonomic risk of the posture in the certain real-world environment. Output includes an indication of the determined ergonomic risk.

Abstract: Embodiments determine manikin posture for simulations of real-world environments. An embodiment automatically generates a phrase by performing a hierarchical analysis using data regarding the real-world environment. According to an embodiment, the generated phrase describes a task, to be simulated, performed by a manikin in an environment. In turn, one or more posture engine inputs are determined based on the generated phrase. The posture for the manikin in a simulation of the manikin performing the task in the environment is then automatically determined based on the determined one or more posture engine inputs.
