Given its wide spectrum of applications, the classical problem all-terminal network reliability evaluation remains a highly relevant in design. The associated optimization -- to find with best possible under multiple constraints presents an even more complex challenge, which has been addressed scientific literature but usually strong assumptions over failures probabilities and/or topology. In t...

Many cities in the Global South are structurally different from Northern, particularly American, on which much of urban sociology’s conceptual apparatus has been based. Thus, depicting them terms a standard vocabulary risks imposing an inappropriate way seeing. We need that is able to accommodate their experience. This special issue contributes work building vocabulary. select five keywords soc...

Servo-actuation system is one of the key executing subsystems of the flight control system of an aircraft. With the development of fly-by-wire control systems, redundant servo-actuation systems have been extensively applied. A servo-actuation system has a long life and high reliability, which results in the lack of failure information. In the mean time, available data is insufficient and imprec...

Introduction Recently, the author attempted to calculate the failure rate (FR) of a series/parallel (active redundant, without repair) reliability network using the Reliability Toolkit: Commercial Practices Edition published by the System Reliability Center as a guide. The Toolkit’s approach for FR calculation for a single branch seemed to be very thorough. So the FR for each individual branch ...

Today’s manufacturing companies are facing multiple and dynamic customer-supplier-relationships embedded in nonhierarchical production networks. This complex environment leads to problems with delivery reliability and wasteful turbulences throughout the entire network. This paper describes an operational model based on a theoretical framework which improves delivery reliability of each individu...
