Design of an Information Carrier Device for a Decision Support System
Independent thesis Basic level (degree of Bachelor), 15 credits / 22,5 HE creditsStudent thesis
Automation in manufacturing leads to produce faster but it also increases level of information and relationship between parts. That makes more dificult to manage the work of operators in the manufacture chain to keep productivity high. Furthermore, manual assembly still plays a vital role in most of the factories all over the world. Hence the importance of implementing an efficient Decision Support System which helps operators to make right decisions. This project approaches to the design of a device to get information to operators. The project belongs to the University of Skövde and it is carried out in cooperation with Volvo Cars. In the first stages of the project diverse information is gathered through the literature review and market research. Literature review approaches to manufacturing organization, mobile information in manual assembly and ergonomics. Market research inquire about handheld devices. Also requirements from operators and environment are adressed. Next stages focus on the generation of ideas to hand in the information to operators. Diverse methodology was used such as brainwriting or morphological chart, leading to three different concepts. The PNI method was employed to select the best one. It consists of using handheld devices against paper sheets or wider screens. Then, three kind of handheld devices were thought. Moodboards and brainwritings were employed to explore shapes and functions. They were presented to coordinators in the factory and one of them was selected to be further developed. Mockups of different sizes were constructed and more drawings specified the dimensions in order to build a CAD model. The final product is small to be easily carried with a wide screen and a stylus to facilitate interaction. Battery ensures withstanding work shifts and components are designed to favor maintenance tasks. The final product was built using CAD software and printed on 3D. Materials, manufacturing methods and technology have been reviewed to ensure viability. Finally, last chapters discuss about diverse topics concerning this project such as ethical, enviromental or economical issues. Further work is proposed, too.
