“…In some other cases, the issue was one of how much human strength and/or endurance was required to perform a manual exertion, with special concern that the final design comply with U.S. NIOSH or DOT policies. This latter use of DHM technology is illustrated in a case study reported by Feyen, Liu, Chaffin, Jimmerson, and Joseph (2000), wherein the University of Michigan's 3DSSPP software was used in an AutoCad application to suggest job design changes to accommodate a larger worker population. Finally, in a few cases, the authors in Chaffin (2001) believed one of the most important features of a DHM was that the human simulations and associated graphics allowed both product and process designers to understand better the potential problems and associated risks a particular population subgroup could have when operating or servicing a proposed design.…”

Digital Human Models (DHMs) are fast becoming an effective tool for performing proactive ergonomics analysis and design. DHM software, such as Jack, SAFEWORK, RAMSIS, SAMMIE, and the UM 3DSSP, are meant to assist a designer early in a product development process, when he or she is attempting to improve the physical design of vehicle interiors and manufacturing workplaces. To become even more effective in meeting such a goal, it is proposed that future DHMs must include valid posture and motion prediction models for various populations. It is argued in this article that existing posture and motion prediction models now used in DHMs must be based on real motion data to assure validity for complex dynamic task simulations. It is further proposed that if valid human posture and motion prediction models are developed, these can be combined with psychophysical and biomechanical models to provide a very powerful tool for predicting dynamic human performance and population specific limitations.

“…However, motions are not simulated but have to be completely directed by the system user, and forces are not computed [9]. Using commercial simulation packages such as LifeModeler [10] and Anybody [11], designers can bring together geometric models of humans and products to compute muscle forces and interaction forces during the use process.…”

This article presents a new methodology that enables designers to include in simulations not only the physics aspects of artifact behavior, but also human actions. The motivation for this research came from the fact that none of the conventional approaches to engineering simulations includes manipulative control of products by users as foreseen by designers. By implementing control over physics simulations, changes in parameters can be introduced that alter the course of the simulated process. As a means to do this, we propose to use scenario bundles, with which designers can operationalize their conjectures of how human users interact with products as a series of interconnected simulations. For the imaginary use process described in a scenario bundle, the designer can specify various product designs, user characteristics and environments, which may in each case lead to different concatenations of simulation actions. The proposal facilitates the exploration of possible mismatches and anomalies in use processes. In this article we have described the theoretical fundamentals and the overall concept of the proposed methodology, as well as its realization as a proof-of-concept implementation. This implementation can be used as a tool to specify scenario bundles and to perform controlled simulations of human-product interaction. The use of the tool is demonstrated through a practical example. Although the implementation has proven to be successful in terms of executing scenario bundles, two bottlenecks need further attention: (i) devising stable algorithms for large deformations in physical interaction simulation and (ii) incorporation of already existing algorithms for simulation of low-level human motion control.

“…On the other hand, the relationships between ergonomic measures and objectives, such as decreasing risk of injury or improving working conditions, are much less clearer. This might be one reason why many papers in the area of workstation design focus on a single ergonomic aspect of the human operator, such as biomechanical strength, metabolic rate, reach assessment, or time predictions (Feyen et al, 2000). This limitation has been discussed in the literature.…”

The increasing use of computerized tools for virtual manufacturing in workstation design has two main advantages over traditional methods; ®rst, it enables the designer to examine a large number of design solutions; and second, simulation of the work task may be performed in order to obtain the values of various performance measures. In this paper a new structural methodology for the workstation design is presented. Factorial experiments and the response surface methodology are integrated in order to reduce the number of examined design solutions and obtain an estimate for the best design con®guration with respect to multi-objective requirements.
