Industry with a high level of investment, such as the oil and gas industry, needs a high level of availability. Product support and its related issues such as spare parts play an important role in maintaining a system at a desired level of availability. Reliability performance is a critical factor for product support and spare parts planning which can be influenced by operational environment. T...

This paper copes with a joint Location-Allocation-Inventory problem in three-echelon base-level spare part support system epistemic uncertainty uncertain demands of bases. The aim the is to propose an optimization model under theory minimize total cost, which integrates crucial characterizations inventory control decisions and location-allocation scheme arrangement periodic review order-up-to-S...

In this paper, we present a real-time fault-tolerant design for a d-dimensional hypercube multiprocessor with two modes of operations and examine its reconfigurability. The augmented hypercube, at stage one, has a spare node connected to each node of a subcube of dimension i, and the spare nodes are also connected as a (d i)-dimensional hypercube. At stage two, the process is repeated by assign...

We discuss SPaRe: selective partial replication, a methodology for concurrent fault detection in finite state machine (FSMs). The proposed method is similar to duplication, wherein a replica of the circuit acts as a predictor that immediately detects errors by comparison to the original FSM. However, instead of duplicating the FSM, SPaRe selects a few prediction functions which only partially r...

This is a study of the relationship between aircraft readiness and spares usage at the squadron level, specifically for the F-4B, CH-53, and TA-4F. The study determines the best combination of aircraft, maintenance man-hours, and spare parts for various budgets. Since the availability of spare parts is a big factor in aircraft readiness, a detailed examination was made of the spare parts resupp...
