Using Availability Analysis to Reduce Total Cost of Ownership
Due to a Printer error, the hardcopy of the 2Q 2010 RIAC Journal contains an error in Table 2 of the article "Using Availability Analysis to Reduce Total Cost of Ownership" by Mr. Bill Lycette of Agilent Technologies. The PDF version of the article is correct, and can be downloaded here. The RIAC apologizes to our readers for any inconvenience that this may cause, and we are working with the Printer to resolve the error in the hardcopy of the Journal. |
Reliability Modeling The RIAC Guide to Reliability Prediction, Assessment and Estimation
|
Few engineering techniques have caused as much controversy in the last several decades as the topic of reliability prediction. One of the primary reasons for this is the stochastic nature of reliability. Whereas many engineering disciplines are governed by deterministic processes, reliability is governed by a complex interaction of stochastic processes. As a result, the metrics of interest in other engineering disciplines are generally much more quantifiable by their very nature. While there is always a stochastic element in any engineering model, the topic of reliability quantification must address its extreme stochastic nature. The intent of this book is to provide guidance on reliability modeling techniques that can be used to quantify the reliability of a product or system. In this context, reliability modeling is the process of constructing a mathematical model that is used to estimate the reliability characteristics of an item. This book reviews possible approaches, summarizes their advantages and disadvantages, and provides guidance on selecting an appropriate methodology based on specific goals and constraints. |

Photonic Component Reliability Technical Report
|
This report summarizes the final results of the Photonic Component and Subsystem Reliability Modeling effort that was performed by Quanterion Solutions Incorporated for the Pennsylvania State University Electro Optics Center (EOC). The work was sponsored by the Naval Air Systems Command (NASC). Due to the environments in which they operate, military/aerospace optical communication systems need more assembly flexibility, fault tolerance, and ability to self-heal. The focus of this project was to develop a method for measurement of reliability levels for photonic components and assemblies that is compatible with MIL-HDBK-217, so that system level designers can efficiently evaluate reliability of systems using fiber optics and photonics. Two types of model forms were developed, one compatible with the Reliability Information Analysis Center (RIAC) 217Plus methodology, and the other with MIL-HDBK-217. |

On 29 August 2009, the US DoD officially adopted ANSI/GEIA-STD-0009, "Reliability Program Standard for Systems Design, Development and Manufacturing" as the replacement for MIL-STD-785, "Reliability Program for Systems and Equipment Development and Production" which was cancelled in 1998. |

AMSAA Reliability Growth Tools and Scorecard
|
The U.S. Army Materiel Systems Analysis Activity (AMSAA) has recently developed a set of Reliability Growth tools and a Reliability Program Scorecard. The tools are available at no charge for US government personnel and government contractors. The reliability growth tools are the latest evolution of the AMSAA reliability growth suite and include the new PM2 reliability growth planning model. The reliability growth planning, tracking, and projection models are easy to use and help the user by performing multiple data checks. The AMSAA reliability scorecard can be applied to assess a system's reliability program. The reliability scorecard provides a quantitative risk score and identifies strengths and weaknesses across eight categories and 40 elements. If you are interested in obtaining the reliability growth models and the reliability scorecard, please click on the link below and enter the requested information. |

U.S Department of Commerce Bureau of Industry and Security Office of Technology Evaluation
|
In June 2007, the U.S. Department of the Navy, Naval Air Systems Command (NAVAIR) asked the Bureau of Industry and Security's (BIS) Office of Technology Evaluation (OTE) to conduct a defense industrial base assessment of counterfeit electronics. NAVAIR suspected that an increasing number of counterfeit/defective electronics were infiltrating the DoD supply chain and affecting weapon system reliability. This study provides (1) statistics on the extent of the infiltration of counterfeits into U.S. defense and industrial supply chains, (2) an understanding of industry and government practices that contribute to the problem, and (3) identification of best practices and recommendations for handling and preventing counterfeit electronics. |

Department of Defense Reliability, Availability, Maintainability, and Cost Rationale Report Manual
|
The Office of the Secretary of Defense and the Joint Staff collaborated on the Reliability, Availability, Maintainability-Cost (RAM-C) Report Manual to assist combat developers, project managers, and engineers to design RAM into systems early in a program. The manual supports life cycle implementation of the Sustainment metric, for which the Chairman of the Joint Chiefs of Staff (CJCS) issued new guidance in May 2007. The Sustainment metric consists of an Availability Key Performance Parameter (KPP) and two supporting Key Systems Attributes (KSAs): Reliability and Ownership Cost. The CJCS guidance requires programs under development to create a balance between RAM performance in the field and the related costs of providing that performance - a distinct paradigm shift within the acquisition community that, once fully implemented, should result in improved value for major acquisition programs. |

SELECT - A Methodology for Acquiring Reliable COTS Equipment
|
“Too often COTS which do not meet the application requirements are used. This leads to higher than anticipated failure rates and poor system mission reliability. Program managers must ensure that COTS components are able to operate satisfactorily in military mission environments. Two excellent detailed guidance manuals for the use of COTS items are:

Bookmarked Version of the Defense Acquisition Guidebook PDF Available for Download from RIAC
|
The purpose of the DoD Defense Acquisition Guidebook is to provide members of the DoD Acquisition Community and its industry partners with a reference to DoD policy and discretionary best practice. The RIAC has enhanced the November 2006 PDF Version of the Guidebook, currently available from the Defense Acquisition University (DAU) website, by adding a comprehensive bookmarked outline to aid in navigation. The RIAC-enhanced version can be downloaded from here. The enhanced version retains all of the hyperlinks incorporated into the DAU PDF versions. It should be noted that, effective 8 December 2008, a new DoD Instruction 5000.02 was issued that cancels DoD Instruction 5000.2, dated 12 May 2003. The Defense Acquisition Guidebook is currently in revision to reflect the new DoDI 5000.02. For the interim, all links in the Guidebook to the cancelled DoDI 5000.2 are redirected to the PDF Version of the DoDI 5000.02. Upon its release, the revised Guidebook will include updated links to the correct sections and specific pages of the new DoDI 5000.02. When the revised Guidebook is released, RIAC will make it available for download. |

Report of the Defense Science Board Task Force on Developmental Test and Evaluation - May 2008
|
The Defense Science Board (DSB) Task Force was asked to assess, from a Test and Evaluation (T&E) perspective, OSD organizational roles and responsibilities; policy and practices in oversight of acquisition programs; assess changes required to establish statutory authority for OSD DT&E oversight; and assess Initial Operational Test and Evaluation (IOT&E) failures due to lack of Operational Suitability. The Final Report provides finding and recommendations addressing broader programmatic issues stemming from systemic changes to the acquisition process. The report also presents findings and recommendations on program structure, requirements definition, contractual performance requirements, alignment of DoD terminology with systems engineering procedures, Commercial Off-the-Shelf (COTS) products, and Systems of Systems (SoS). The RIAC "Selection of Equipment to Leverage Commercial Technology" (SELECT) work was cited as 'excellent detailed guidance' for the use of COTS items. |
