This methodology consists of modifying a base reliability estimate with process grading factors for the following failure causes: parts; design; manufacturing; system management; induced; and no defect found. These process grades correspond to the degree to which actions have been taken to mitigate the occurrence of system failure due to these failure categories. Once the base estimate is modified with the process grades, the reliability is further modified by empirical data taken throughout system development and testing. This modification is accomplished using Bayesian techniques which apply the appropriate weights for the different data elements. Advantages of this new methodology are that it: uses all available information to form the best estimate of field reliability; is tailorable; has quantifiable confidence bounds; and has sensitivity to the predominant system reliability drivers.","PeriodicalId":275301,"journal":{"name":"Annual Reliability and Maintainability Symposium. 1998 Proceedings.

This problem can be solved by utilizing the methods of decomposition and aggregation. That is, dividing the system into smaller subsystems, solving the subsystems separately, and then synthesizing these results to produce the larger systems' solution. In this paper, we demonstrate a decomposition scheme where independent subtrees of a fault tree are detected and solved hierarchically, a subtree is replaced by a single event in the parent tree whose probability of occurrence represents the probability of the occurrence of the subtree. The decomposition and hierarchical solution can be more useful in case of fault trees with dependencies. Instead of solving the whole system as a Markov model only the appropriate subsystem needs to be analyzed as a Markov model.","PeriodicalId":275301,"journal":{"name":"Annual Reliability and Maintainability Symposium. 1998 Proceedings.

Reliability prediction tool has two aspects. First it is used in a priori fashion to scale an initial reliability prediction based upon which development process initiatives are used.

One feature is that the new model introduces a variance measure into the MTBF prediction. The CAE presentation focuses on the a priori part of the model since that is deemed to operationalize a concurrent engineering focus in a timely manner for new product development.","PeriodicalId":275301,"journal":{"name":"Annual Reliability and Maintainability Symposium. 1998 Proceedings.

However, CAD systems do not analyze the product design for disassemblability, a significant part of maintenance. This paper presents a new methodology for performing disassembly evaluation of CAD models of designs for maintenance. This methodology involves analyzing the product for disassemblability utilizing several disassembly techniques, such as selective disassembly and destructive disassembly, to assess: (i) the ease of product disassembly for maintenance, (ii) disassembly sequencing to maintain a selected set of components and (iii) disassembly cost for maintenance. The methodology utilizes a metric for quantitative assessment of the product in order to arrive at an acceptable design and to compare alternate designs for maintenance. Moreover, the disassembly methodology presented in this paper can serve as a basis for identifying an efficient product design for maintenance.","PeriodicalId":275301,"journal":{"name":"Annual Reliability and Maintainability Symposium. 1998 Proceedings.

This is because the consideration of all possible combinations of failures in a system is impractical for any but the very simplest example systems. Even if simulation is used to automate the work of producing an FMEA report, consideration of all possible combinations of failures is not possible, and even if it was possible, an engineer could not be expected to spend the time needed in order to read, understand and act on all of the results. This paper shows how to use approximate failure rates for components to select the most likely combinations of failures for simulation, and how to prune the resulting report to such an extent that it is practical for an engineer to study and act on the results. The strategy outlined in the paper has been applied to a number of automotive electrical subsystems, and the results have confirmed that the strategy described works well for realistically complex subsystems.","PeriodicalId":275301,"journal":{"name":"Annual Reliability and Maintainability Symposium. 1998 Proceedings.

With such a software tool, maintainability issues can be considered from the early stages of the design process, and possible maintainability problems can be identified early and avoided without costly design modifications. In current product design and development, maintainability activities are required according to maintainability related standards, and the applicable methods are also specified in standards. The primary objective of CAMDA is computerizing these methods. In addition to standard methods, some other technologies such as stochastic network technologies, artificial neural network technologies and computer animation technologies are also applied to maintainability prediction and analysis. It must be emphasized that CAMDA is not only a computer technology application research, but also an effective and practical software tool applicable to most product design and development programs, and it meets engineers' needs. So, the development of CAMDA is engineering-oriented. It will relieve designers and maintainability engineers from miscellaneous business, and improve product quality without significant increase in design cost.","PeriodicalId":275301,"journal":{"name":"Annual Reliability and Maintainability Symposium. 1998 Proceedings.

The survey provides a common language across disciplines within an organization, as well as between that organization and an external consulting group. What is more, the toolkit acts as a staffing filter, ensuring that the most suitable staff resources address the most urgent priorities. This approach serves to shape and challenge the common assumptions and attitudes that often thwart long term business success. Brief comments on the typical limits of corporate strategic planning illustrate the benefits of a constructive skepticism in reconsidering widely held perceptions. Considering overall responses from nearly 200 participants with 98 corporate divisions, the participants generally rate themselves highly for competitive strategic planning, followed by process management and organizational approaches.

Three equally significant hurdles have been overcome during the development of this software, with the following results: state-of-the-art algorithms have been developed to find part-removal paths, create swept volumes, and decimate large models for interactive visualization. A powerful yet easy-to-use application has been developed that can efficiently manipulate large databases. The application has been integrated into many aspects of a large industrial design cycle. The application, Galileo, is being actively used by GE Aircraft Engines (GEAE). The visualization and maintainability analysis technology embedded in this software has eliminated the need for costly physical mockups and pushed maintenance issues to the earliest stages of the design cycle. The tool has facilitated concurrent engineering through visually enhanced communications.
