“…Equation ( 1) is a generalized formulation for FOM proposed by Ferris [129]. Table 5 includes the equation, which was found in a second publication by Ferris [130], as well as the mathematical approaches used to tackle system resilience.…”

“…This benefit is not exclusive to one sector of the industry or to a particular field. FOM is conveniently fitting to any system in any greenfield (i.e., building new systems in a new climate) or brownfield (i.e., modifying existent systems) development project [130]. It must be clarified that FOMs, in turn, can convert into measures of resilience when they signal the value outputted by the system, or v ij , where i tallies performance attributes up to n in the trade-space analysis, and j truncates the system's lifecycle into m equal timeslots at t = 0.…”

The pressures of an everchanging world have impacted the ways in which service-based systems operate, along with their forms and boundaries. Resilience and survivability have been treated interchangeably when readying a system to remain true to its functions despite disturbances. Some situations prove the concepts may not always be the equivalent of the other, not even the consequence of the other. There may come scenarios where system components fail to adhere to certain predefined thresholds and cross a breaking point. It is therefore proposed in this study that systems can be survivable, instead of resilient, when they comply in time with the resurgence property. This property signifies the systematic behavior of overcoming a certain stagnation period and, after a time range, return as a transformed system with new functions and challenges. Through this study, it was detected that the symmetries between resilience and survivability are only superficial if systems suffer breakages after misconceiving the true causes of failure. Still, a lack of consensus among scientists and practitioners remains an issue when applying resilience and survivability in their own problems. Although workful, pushing to achieve a greater consensus would signify optimal performance in multifaceted systems involving technical, social, and economic challenges.

“…Further, there have been arguments made to use resilience in analysis of alternatives for military systems [44] and from a mission engineering perspective [45]. Our proposed measure is similar to the value-oriented measure described by Ferris [46,47], except we provide a means to define value as mission impact, whereas Ferris presented a general framework.…”

This article develops a method to model, analyze, and design military microgrids with the objective to improve their resilience in the face of disconnections from the larger electrical grid. Military microgrids provide power to installation and base facilities to enable base mission objective accomplishments that are related to national security. Previous research, tools, and methods for microgrid design and assessment do not adequately address resilience in terms of accomplishing mission objectives and instead primarily focus on economic outcomes. This article proposes a novel metric to quantify microgrid resilience in terms of its ability to minimize the impact of power disruption on missions supported by the microgrid. The metric is used in a novel design method to ensure an islanded military microgrid can continue operations while disconnected for a two-week duration. Our model examines the ability to continue mission operations subject to various microgrid disruptions as well as equipment reliability.
