- In digital human modelling (DHM), ergonomics evaluations are typically done with few human models. However, humans vary a lot in sizes and shapes. Therefore, few manikins can rarely ensure accommodation of an entire target population. Different approaches exist on how to consider anthropometric diversity. This paper reviews current DHM tools and clarify problems and opportunities when working with anthropometric diversity. The aim is to suggest functionality for a state of the art DHM module and work process for considering anthropometric diversity. The study is done by an analysis of some of the current DHM systems and by interviews of personnel at car companies about their way of working with anthropometric diversity. The study confirmed that critical production simulations are often done in early development stages with only one or a few human models. The reason for this is claimed to be time consuming processes, both at the creation of the human model but mainly when correctly positioning the model in the CAD environment. The development of a new method and work process for considering anthropometric diversity is suggested. Necessary features for such a module are that it shall be easy to use and not require expert knowledge about the consideration of anthropometric diversity. It shall also be configurable and transparent, in a sense that it should be possible to work with own anthropometric data and ergonomics evaluation standards. The module has to be flexible and have different entrances depending on the type of anthropometric problem being analyzed. An improved work method is expected to lead to faster and more correct analyses.

- Modern manufacturing information systems allow fast distribution of, and access to, information. One of the main purposes with an information system within manual assembly is to improve product quality, i.e. to ensure that assembly errors are as few as possible. Not only must an information system contain the right information, it must also provide it at the right time and in the right place. The paper highlights some of the concerns related to the design and use of information systems in manual assembly. The paper describes a study that focuses on the correlation between active information seeking behaviour and assembly errors. The results are founded on both quantitative and qualitative methods. The study indicates that by using simplified information carriers, with certain characteristics, the assembly personnel more easily could interpret the information, could to a higher degree be prompted (triggered) about product variants and could also be able to prepare physically and mentally for approaching products arriving along the assembly line. These conditions had positive influence on quality, i.e. gave a reduction of assembly errors.

- The overall rationale and assumption for the research project presented in this paper is that a fast, easy to use, and reliable procedure to predict and validate manual assembly tasks is of major importance in product and production development processes to ensure high and robust product quality and process performance. A basic condition for the research is the belief that tools with such functionality are currently not available for companies to utilise in their development processes. Hence more research and development is needed in the area. This paper describes the basic concepts and initial steps taken in the recently commenced research project IMMA - Intelligently Moving Manikin.

- Digital Human Modeling (DHM) tools are useful for simulating human work and proactively evaluating ergonomic conditions. IMMA (Intelligently Moving Manikin) is a project that aims to develop software that combines digital human modeling and path planning. The work in the IMMA project is divided into a number of work packages that gradually increases the complexity of the problem. This poster paper regards both the functionality for ergonomics assessment and consideration of anthropometric diversity in the DHM tool being developed. Reviews of current DHM tools and interviews with DHM users and ergonomics specialists were done to clarify problems, needs and opportunities when working with anthropometrics and ergonomics evaluations. Interviews showed that simulations and following evaluations are almost solely based on static postures and with few human models. The main reason for this is claimed to be complex and time consuming processes when creating and evaluating simulations. Both the review of current DHM tools and the interviews confirmed that there is an evident need for more time-dependant evaluation methods and a better coverage of the intended users’ diversity. Attained knowledge from the analysis of current DHM tools and interviews are used to create work processes and two specific modules intended to be implemented in the new IMMA DHM tool. Key issues for the modules are ease of use and flexibility. The overall objective with the IMMA DHM system is to offer a tool that support faster and more correct ergonomics analyses.

- This paper presents an experimental study made on the use of different kinds of information sources in manual assembly. The general idea is that only the necessary information should be presented to the worker and it should be presented where and when the worker needs it as this is believed to both save time and unload cognitive strain. To account for the latter two aspects of this thought, where and when, this paper investigates the use of a handheld unit as an information source in manual assembly. Having a mobile information system, such as a Personal Digital Assistant (PDA), that can be carried with you at all times, as opposed to a stationary one, such as a computer terminal, is hypothesized to greatly improve productivity and quality. Experimental results show that the use of a PDA significantly improves quality whereas productivity does not significantly improve.
