In the Maintenance Planning tool, choose the Inspection Replacement plot type on the control panel, and then enter the estimated costs.

Find the optimal inspection interval and the optimal scheduled replacement interval for minimizing the cost in one replacement cycle.

Find the optimal inspection interval and the optimal scheduled replacement interval for minimizing the cost in the long term.

The cost for each inspection is $10, and the fraction of the failure time for detecting an oncoming failure is 0.9. For an unplanned replacement, the cost is $500. The Weibull distribution has parameters beta,! = 2.847494 and eta,! = 108.420135.ДЄssume that the average cost for a planned replacement of the device is $20. The following picture shows the Weibull++ standard folio that contains the data and distribution. The failure times of the device are recorded and a Weibull distribution is used to model the data. Assume that we are going to use the Maintenance Planning tool in Weibull++ to analyze a device that is assembled as part of a system.

The theory behind this strategy is discussed in the Systems Reliability Analysis Reference book, but we will provide a brief explanation here.ДЇor an item that is replaced either at the time of failure or at the time of the scheduled maintenance interval x,!, the expected cycle length is:Д®(text Example Reliasoft Software Minimizing the long term maintenance cost per unit time is the most popular objective for adopting a preventive replacement strategy.

In this section, we will discuss how to find the optimal maintenance and inspection intervals in order to minimize the long-term and short-term maintenance costs. Inspections can also be used to minimize either the long-term or short-term costs. Similarly, periodic inspections are done to detect oncoming failures and replace the component before a failure occurs. A replacement cycle is defined as the time when a failure occurs or the time of the scheduled replacement when no failure occurs. An optimal time interval exists if the failure rate increases with time and the cost of failure is much higher than the cost of a scheduled replacement.ДЄnother alternative is to minimize the short term cost per unit time, such as in one replacement cycle. For example, the commonly used preventive maintenance strategy is to replace an aged item at a given time interval in order to minimize the long term cost per unit time.

Index Additional Reliability Analysis Tools A shape factor of 2.0 is a Raleigh distribution, while a Weibull shape factor of about 3.0 or above represents an approximately normal distribution. For example, a Weibull shape factor of 1.0 represents an exponential distribution. In other words, the Weibull routine reveals, rather than masks, the correct shape of the data's density curve.
