The paper summarizes the results of an ergonomic analysis of firearms with regard to anthropometric dimensions of selected populations. For evaluation 3D digital human models, which represent currently the best technology, have been used. Analyses are performed for three major population groups (Americans, Europeans and Asians). Ranges to controls (e.g. lock, trigger, etc.) are critically evaluated. The grip of the firearm according to the position of shooters wrist is also a subject to critical analysis. At the end of the paper the deficiencies found are discussed as well as a bad situation regarding the availability and timeliness of anthropometric dimensions of Czech population. Further work that is described will be focused on the creation of national anthropometric database. The database shall include the dimensions of the hand and will be created according to the rules of EN ISO 15535. The data will be suitable for the design of other hand tools from various sectors.
In this time of globalization, when every company needs to stay competitive to survive in the market, it is still more necessary to reduce costs, streamline production, innovate the product or whole production systems etc. This contribution is focused on using the concept of digital factory in the planning phase, specifically on setting operation times in a packing workplace. Times are set by two methods, MTM1 and UAS. After this planning phase, the process is simulated in a virtual environment. After simulations and experiments with virtual workplace, we created a real workplace, and conducted real experiments. At the end of the paper is a comparison between real and virtual workplaces.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
