Tiivistelmä
One of the most in infuential factors when talking about industrial products are quality and reliability of the products. As company grows, grows also need for reliability plan. Purpose of this thesis was to present a variety of different reliability tools, and give examples of utilizing these tools.
First tools revolved around Design for Reliability methodology. Its fundamental idea is to implement the reliability in the design process. Methods from the Design for Reliability consists of many different tools, while concentrating on preventive design with di erent analysis and simulations, and by using iterative design methods for testing, and redesign. Second set of tools was presented as a computer aided design.
These tools takes advantage on developing computers, and digitalization, which can be utilized throughout the design process. Simulation for mechanical, electrical, and thermal phenomena can increase the reliability during the design process and in the meantime decrease time to market.Third part consists the important part for every design process, an analysis and selection of the components used. Errors on choosing the right component can have effects seen at long after the production process is over. It is important to know how to control the components reliability parameters, and also be aware the different ways of giving the reliability information. Also tolerances, parameter degradation and rating of components are discussed over the third part of this thesis.
At each tool sets, the possible use is discussed during the presentation of the tools with the proper and right timed use. Also the possible impact the proper use of these tools might have to the new product development process is discussed.
