These master’s theses present the review of design support methods. Mechanical part design plays an important role whether company will succeed in market or will fail.

In the first part I describe some systematical design support methods and tools, such like axiomatic design and group technology. From my point of view there are three measures of the design process: cost, quality and time, which are pivotal in design process. Regardless of the product being designed – whether it is an entire system or some small subpart of a larger product – the customer and management always want it cheaper, better and faster. Design decisions directly determine the materials used, the goods purchased, the time when it should be purchased, the part to be assembled, the shape of those parts, the product sold, and, in the end, the scope of management.

In the next parts I describe main CIM (computer integrated manufacturing) elements and DFX (design for X) methods, and importance to use these systems and methods in factories. The development of the DFX strategies arose from the need to understand what is important after the design stage. Since design typically will set 70% of the cost of a product, it is very important to make sure designs are made with the correct objective in mind.

In the case study I’m describing production of bikes. I propose some of the possibilities to make easier manufacturing, using DFX methodology. During this work I tried to apply theoretical knowledge about design process and to use design support methods.

Work on this project gave me impulse to search more information about the design process. And moreover, it gave me opportunity straight to apply my theoretical knowledge in practice. Also it enabled me to find out other problems in our industry: such as cost calculation, communication problem between different departments.
