  • product life cycle cost analysis state of the art review
    International Journal of Production Research, 1998
    Co-Authors: Yetunde Asiedu, P. Gu
    Abstract:

    In an attempt to improve the Design of products and reduce Design changes, cost, and time to market, concurrent engineering or life cycle engineering has emerged as an effective approach to addressing these issues in today's competitive global market. As over 70% of the total life cycle cost of a product is committed at the early Design stage, Designers are in a position to substantially reduce the life cycle cost of the products they Design, by giving due consideration to life cycle cost implications of their Design decisions. Increasing recognition of cost competition has spurred the development of methodologies such as Design for manufacturability, Design for assembly (DFA), Design for producibility, Design for Maintainability and Design for quality, in the Design for 'X' realm. Although these methodologies have for the most part proven successful in reducing cost, the Design evaluation criterion in most of these methodologies is not cost. Therefore methodologies and tools are needed to directly provid...

Therefore methodologies and tools are needed to directly provide cost information to Designers. Life Cycle Cost (LCC) analysis provides a framework for specifying the estimated total incremental cost of developing, producing, using, and retiring a particular item. This paper looks at the issues of LCC analysis and the tools that have been developed to provide engineers with cost information to guide them in Design.

  • Military digital avionics fiber-optic network Design for Maintainability and supportability
    IEEE Aerospace and Electronic Systems Magazine, 2006
    Co-Authors: M.w. Beranek, A.r. Avak, R.l. Van Deven
    Abstract:

    The use of avionics fiber optics technology is becoming more prevalent. Optical fiber is immune to electromagnetic interference, gives increased bandwidth, saves space, and reduces weight. If used smartly, fiber optics technology can effectively "future-proof" avionics networks. The Boeing 777 PlaneNet program provided a textbook example of "how to" build and deploy fiber optic networks on commercial aircraft (Anderson and Beranek, 1998). Tactical aircraft, however, do not yet have history to draw upon for operational readiness, particularly in the area of aircraft squadron fiber optic network Maintainability and supportability. Military aircraft fiber optic network Designs must not only consider the harsh operational and maintenance environment, but also need to be deployed in a maintainable and supportable manner. The term Maintainability defines how quickly, easily, and cost effectively an avionics fiber optic network Design can return to operational status (whether by preventive or corrective maintenance). Mean time to repair (MTTR) is used to quantify and measure Maintainability. Supportability, on the other hand, is the degree to which the avionics fiber optic network Design characteristics minimize the logistics resources (people, skill levels, parts, publications, tools, test equipment, space) required to sustain the system's operational availability (AO) at an affordable cost throughout the life of the system

  • Military digital avionics fiber-optic network Design for Maintainability and supportability
    24th Digital Avionics Systems Conference, 2005
    Co-Authors: M.w. Beranek, R.l. Van Deven
    Abstract:

    The Boeing 777 PlaneNet program provides a textbook example of "how to" build and deploy a fiber optic based avionics local area network on commercial aircraft (Anderson and Beranek, 1998). Tactical aircraft, however, does not yet have a time-tested process to draw upon for operational readiness lessons learned, particularly in the area of aircraft squadron fiber optic network Maintainability and supportability. The tactical aircraft fiber optic network Design team must consider both the harsh avionics operational environment and the harsh avionics maintenance environment - as many fiber optic components from the commercial sector are not adequate for the tactical aircraft mission environment; and many fiber optic maintenance support equipment options available from the commercial sector are not adequate for use on an aircraft carrier or expeditionary airfield. In this paper we attempt to define items necessary to ensure military avionics fiber optic network Design interfaces are deployed in a maintainable and supportable manner. The term Maintainability defines how quickly, easily, and cost effectively an avionics fiber optic network Design facilitates its' return to operational status (whether by preventive or corrective maintenance). Mean Time To Repair (MTTR) is used to quantify and measure Maintainability. Supportability, on the other hand, is the degree to which the avionics fiber optic network Design characteristics minimize the logistics resources (people, skill levels, parts, publications, tools, test equipment, space, etc.) required to sustain the system's Operational Availability (A/sub 0/) at an affordable cost throughout the intended life of the system.

  • a structural model for cost effective building maintenance through Design for Maintainability
    2016
    Co-Authors: Shubashini Ganisen
    Abstract:

    Building Maintainability is renowned in the lack of integration with building Design. This has been seen as one of the major factors contributing to various problems facing the building industry, precisely the increasing building maintenance costs. Initial study and critical reviews on literatures reveals that there is a need to identify a comprehensive building Design for Maintainability criteria and indicators to reduce the overwhelming cost of building maintenance through mitigation of defects. To address the above issues, this research was carried to establish an exhaustive building Design for Maintainability criteria and indicators to achieve cost effective building maintenance. Total of nine Design for Maintainability criteria, thirty-eight indicators and eighteen cost effective building maintenance indicators were identified and validated in two phases of survey and analysis. In the first phase, Delphi survey was conducted and in the second phase Structural Equation Modeling (SEM) technique was used to validate, develop and determine the structural model of building Design for Maintainability for cost effective building maintenance. This research aims to address the long pending quest of incorporating Maintainability during the building Design phase and form as basis to promote facility management practices in the building Design phase. The results of this research firmly established the structural relationship model among building Design Maintainability criteria and indicators to achieve cost effective building maintenance. The structural model developed through this research can greatly benefits and being a useful reference in the construction industry particularly for the architects and Designers to incorporate Maintainability during the building Design phase to achieve cost effective building maintenance.

  • the identification of Design for Maintainability imperatives to achieve cost effective building maintenance a delphi study
    Jurnal Teknologi, 2015
    Co-Authors: Shubashini Ganisen, Izran Sarrazin Mohammad, Jawahar L Nesan, Abdul Hakim Mohammed, Gunavathy Kanniyapan
    Abstract:

    Incorporating Maintainability during the building Design is essential to increase overall performance of the building including quality and cost as; the management and operation process of facilities can have a significant impact on cost, health and safety, energy and quality. As a result, a more effective and efficient building facility will be turned over during the post occupancy stage. Literature review reveals that there is a need to implement Maintainability during the building Design phase; mainly due to the increasing life-cycle cost of the building facilities. A critical review of the literature has been carried out to explore the consideration of Maintainability during the building Design and subsequently identifies a set of criteria and indicators to be applied during the building Design phase to achieve cost effective building maintenance. Thus, this paper opted a four-round Delphi questionnaire survey to identify the relevant Design for Maintainability criteria and indicators to achieve cost effective building maintenance. 8 Designs for Maintainability criteria along with the indicators for each of the criterion have been identified. These Design for Maintainability indicators help the building architects to incorporate Maintainability practice during the building Design phase and thus help to achieve cost effective maintenance. This paper aims to address the long pending quest of incorporating Maintainability during the building Design phase and consequently achieve cost effective building maintenance.
