- 23:58, 16 March 2023 Lisa Hacker talk contribs created page Two Level Fractional Factorial Designs (Created page with "{{Template:Doebook|8.1}} ==Two Level Fractional Factorial Designs== As the number of factors in a two level factorial design increases, the number of runs for even a single replicate of the <math>{2}^{k}\,\!</math> design becomes very large. For example, a single replicate of an eight factor two level experiment would require 256 runs. Fractional factorial designs can be used in these cases to draw out valuable conclusions from fewer runs. The basis of fractional factor...")

- 18:48, 10 March 2023 Lisa Hacker talk contribs created page Using Maintenance Tasks (Created page with "{{Template:bsbook|7.3}} {{TU}} =Using Maintenance Tasks= One of the most important benefits of simulation is the ability to define how and when actions are performed. In our case, the actions of interest are part repairs/replacements. This is accomplished in BlockSim through the use of maintenance tasks. Specifically, four different types of tasks can be defined for maintenance actions: corrective maintenance, preventive maintenance, on condition maintenance and inspe...")

In the prior examples, we used a repair distribution to identify how long it takes to restore a component. The factors that one chooses to consider in this time may include the time it takes to do the repair and/or the time it takes to get a cr...")

Note that there are closed-form solutions for both the normal and lognormal reliability that can be obtained without the use of the Fisher information matrix. However, these closed-form solutions only apply to complete data. To achieve consistent application across all possible data types, Weibull+...")
