Using cost-based mathematical model and principle 80/20 to improve decision making for risk priority at FMEA

Producing in quality is often hard and time- consuming job, with many risks and problems. One of these risks and problems can be defect (failure) appearance. These problems can be controlled with various tools, techniques, and methods. One of them frequently used in industry is Failure Mode and Effect Analysis wider known as FMEA. FMEA has both many advantages and also many disadvantages. One of these various disadvantages is that cost is not included into decision making during risk prioritization. Cost is one of very important factors during the risk evaluation phase, especially the external cost which can affect customer directly. Therefore, this research is mainly oriented to finding solution for integration of costs into traditional way of risk prioritization. Study is extension of previously conducted study by Banduka et al. (2016) with using of principle 80/20 to define risk prioritization by adding coefficient of product (which failure affects) value into traditional pattern for RPN. In this research, that new pattern for RPN was extended by new coefficient for profitability of corrections and new RPNK was achieved. At last, comparation of previous state with traditional RPN and new RPNK prioritization was presented.
