A fuzzy decision support system for equipment repair under battle conditions

Dynamic power management with fuzzy decision support system

“…Note that although we have used a two-state HDD, the proposed algorithm however can be applied to multi-state systems. We compare the objective functions for different algorithms in different situations using (5). The goal is to reduce the power consumption, delay, switching rate, and computation.…”

“…The developed fuzzy number is a triangular number whose core is the number generated by the estimation approach, and whose support is the interval produced by the minimum and the maximum of the performance measure of the approach in the N preceding moments. The Support of a fuzzy set F is the crisp set of all points in the Universe of Discourse [5]. In the initial states of the system, due to lack of an interval of N moments, crisp numbers are converted to fuzzy singletons (a fuzzy set whose support is a single point).…”

“…We use only one algorithm in each time slot and hence the extra overhead of the new approach, compared to using the algorithm itself, is the overhead due to the decision making process. The decision making may be characterized as a process of choosing 'sufficiently good' alternative(s) or course(s) of action, from a set of alternatives, to attain a goal or goals [5]. The decision making deals with a set of conflicting goals that usually are difficult to achieve simultaneously.…”

Incorporating fuzzy approaches for production planning in complex industrial environments: the roll shop case

“…Fuzzy systems are a widely used approach to solving production planning problems in different environments (Guiffrida and Nagi, 1998), such as finding an optimal scheduling for coordinating delivery activities (Xue et al, 2001), just-in-time planning of manufacturing systems (Wang et al, 1999), job dispatching in flexible manufacturing systems (Lee et al, 2001) or job scheduling in workshops (Sakawa and Mori, 1999;Sakawa and Kubota, 2000;Simoes-Marques et al, 2000).…”

Towards the Development of a Capability Assessment System for Flood Risk Management

“…VIRTS enables an end-user to design and modify various risk scenarios, however it does not provide risk scenarios related to natural disasters such as flood and earthquake scenarios. Another study proposed an IT system for detecting and evaluating problems in the equipment capability during operational use [4]. A proposed IT system for mass evacuation [6], which aims to aid decision-makers in understanding complexity within the pre-alert situation and evaluates the adequacy of evacuation plans for areas, however the system has not been tested and validated.…”
