Failure mode and reliability analysis is particularly important for robot manipulators to be deployed in remote environments, where inspection and repair are di cult, and reliability is of prime importance. This is particularly true for manipulators involved in hazardous waste management operations, where failure could be both expensive and highly dangerous. In this paper, we describe a Fault T...

Fault Tree Analysis (FTA) has become a popular tool for use in the Space Industry for the System Safety Engineer. The fault tree is used for everything from tracking hazard reports to investigating accidents, as well as presentations to management. Yet, experience in the space industry has shown the fault tree is used most often for purposes other than its original intent, namely for evaluating...

This paper illustrates how Chittaro’s methods of modelling functions and goals can be applied to a reliability procedure known as Failure Modes and Effects. The use of functional models links structure to purpose and the central theme of this paper is to show how the design objectives of a system can be linked to the structure using functional models as an intermediary. The models are demonstra...
