An Analytical Approach to Reliability, Failure Forecasting and Product Quality Free

Gas turbines and many other products can suffer from poor quality at different times in their life cycles. The cause may vary from mistakes in the manufacturing process to a design that does not meet the rigors of the actual usage environment. In many cases there is a huge negative impact on the cost of the warranty and hence on the bottom line of the producer as well as the user. The most logical place to start curing the problem lies not in an immediate redesign effort, but in quantifying the failure problem. This paper shows how a typical problem of failures impacting quality and the resulting warranty difficulty, can be solved by quantifying the future failure frequency, or failure forecasting. Once this is done it is possible to simply quantify the degree of improvement required and to control the costs in making the needed fixes. Since the failure forecasting solution can be done entirely on a desktop PC it is not a complicated or long drawn out process. Every engineer or analyst within the smallest to the largest company can make all of the required analyses in minutes for a simple problem and in an hour or so for many complex problems. Almost any conceivable product can be treated in this manner using the software available once the simple procedure is learned.
