Maximizing system availability through joint decision on component redundancy and spares inventory

To describe the self-adaptive character of combat unit (CU), which may not be able to give precise explanation by conventional mission measurement, we present a measurement method orienting to unsuccess prevention for CU mission. Firstly, the task characteristics of multi-phase and multi-level of CU are explained. On this basis, a hierarchical measuring system including measure of capability deviation, relating to basic task unsuccess and composite task is given by quantifying the disturbance. Based on unified measurement, the basic task unsuccess according to presumable domain from required domain is quantified, and the composite task unsuccess is also quantified. Finally, a case of capability deviation measurement and its impact on overall unsuccess are presented for check.

The study discusses how some challenges from a small sample fatigue test can be analysed statistically and resolved. In terms of data dispersion, fatigue data are initially processed by confidence, and then, the fatigue life curve is replaced by the parabolic reliability approximation. Fatigue data under various reliability levels are obtained. Instead of the traditional single S–N curve, the mean value curve and mean square deviation curve of the S–N curve are computed based on the processed fatigue data. The S–N curve with reliability is deduced by applying quantile theory. The S–N curve is improved by considering the effects of low‐amplitude load strengthening. The benefits of the modification are visible in the comparison of the fatigue life before and after low‐amplitude load strengthening. Copyright © 2016 John Wiley & Sons, Ltd.

“…Wang et al [19] present a multi-objective model for safety-based design and maintenance optimization of large marine engineering systems. In other capital-intensive industries, several works consider the implementation of build-in redundancy for critical components (i.e., having a number of identical parts in parallel) and investigate the trade-off between the increase 8 in the initial system cost and the decrease in maintenance and downtime costs during the life cycle (see, e.g., [20,21,22]). Some other works consider the impact of different component reliability levels on the total system LCC (see, e.g., [23,39]).…”
