CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): This paper presents a novel and simple approach to reliability analysis of phased-mission systems. The technique presented in this paper transforms a phased-mission system into several non-phased-mission systems, and thus allows each phase to be modeled separately. The mission succeeds as long as every phase.

    This paper proposes a new simulation model for evaluating phased mission systems reliability. The model simulates the components’ process of failure within mission life depend upon a modularized a phased mission system model. With the Monte Carlo method together, the reliability of phased mission and mission phases can be analyzed. Downloadable (with restrictions)! A phased-mission system (PMS) involves multiple, consecutive, non-overlapping phases of operation. The system structure function and component failure behavior in a PMS can change from phase to phase, posing big challenges to the system reliability analysis. Further complicating the problem is the functional dependence (FDEP) .

    that the systems being analyzed perform a single phased-mission. With the increased use of automation in industries such as aerospace, chemical, communication networks, electronics, transportation and nuclear, phased-mission system (PMS) analysis is being recognized as an appropriate reliability analysis method for a large number of problems [1].

A fast and efficient phased mission reliability analysis can be used to support the decision making process of autonomous vehicles.

Phased mission modelling. Phased missions are used to define the behaviour of a system during different parts of the mission and to perform the analysis. The following characteristics determine a phased mission: •Cited by: from book Handbook of Performability Engineering A method is proposed for the phased-mission reliability analysis of the studied systems based on.

1. Introduction. A phased mission system (PMS) is one that performs several different tasks or functions in sequence. The periods in which each of these successive tasks or functions takes place are known as phases.Examples of PMSs can be found in many practical applications, such as electric power systems, aerospace systems, weapon systems and Cited by: 5.

Reliability Analysis of Phased-Mission System in Irrelevancy Coverage Model Abstract: In a phased-mission system (PMS), an uncovered component fault may lead to a mission failure regardless of the status of other components, and the reliability can be analyzed with traditional imperfect fault coverage model (IFCM).

In a phased mission the relevant system configuration (block diagram or fault tree) changes during consecutive time periods (phases).

Many systems are required to perform phased missions. A classic example is a space vehicle. In this chapter, a state-of-the-art review of various analytical modeling techniques for reliability analysis of phased-mission systems (PMS) is presented.

The analysis approaches can be broadly classified into three categories: combinatorial, state-space oriented, and modular. At the RAMS Conference, a paper entitled Reliability analysis of phased-mission systems: a practical approach was presented.

At the RAMS Conference, a paper entitled Reliability analysis of phased-mission systems: a practical approach was presented. This paper established an alleged novel and simple approach to reliability analysis of phased-mission systems.

The technique presented in that paper transformed a phased-mission system into several nonphased systems, thus allowing for each phase. Phased mission systems are frequently encountered in industrial fields, and many approaches have been proposed in the literature to compute their reliability.

After a short review of the existing literature, this paper aims to illustrate the use of two reliability analysis methods applied to a simple, but not trivial, problem.

Many systems are required to perform phased missions. A classic example is a space vehicle. A reliability analysis for a phased mission encounters complexities not present with just one phase, but can be transformed into an analysis of a synthetic single phase : betweenthereliabilityof(redundant)systemsandthereliabilityof ility inthe sense used here isthe "probabi- lity ofa deviceperforming its purposeadequately forthe period of.

This paper presents a novel and simple approach to reliability analysis of phased-mission systems. The technique presented in this paper transforms a phased-mission system into several non-phased-mission systems, and thus allows each phase to be modeled separately.

The mission succeeds as long as every phase successively executes its requirements, and failed component(s) of any phase. Abstract: A method for automated analysis of phased mission reliability which considers the problem in terms of the construction of a continuous-time discrete-state Markov model and uses a standard Markov-chain solution technique that is adapted to the problem of phased missions is presented.

The resulting state space is the union of the states in each independent phase. phased missions. uses a serial connection for all the reliability blocks of each phased mission and then suppose the solving of the system’s reliability at the end of each phase.

But, it is a conservative approach. A more exact approach suppose to build a block diagram for an equivalent system in the following way: in the block.In a phased mission the relevant system configuration (block diagram or fault tree) changes during consecutive time periods (phases).

Many systems are required to perform phased missions. A classic example is a space vehicle. A reliability analysis for a phased mission encounters complexities not present with just one phase, but can be transformed into an analysis of a synthetic single phase .We consider the reliability analysis of phased-mission systems with dependent common-cause failures in this paper.

A phased-mission system (PMS) is a system supporting a mission characterized by multiple, consecutive, and non-overlapping phases of operation.
