This book was released on 1976 with total page 107 pages. Available in PDF, EPUB and Kindle. Book excerpt: The reliability improvement warranty (RIW) is a relatively new procurement concept which may potentially make a significant contribution to the Department of Defense (DOD) goal of lowering the life cycle costs of weapons systems. A major factor delaying full scale application of the RIW concept is uncertainty concerning the impact that widespread usage would have on competition for DOD procurements. This study was limited to a comparison of the six existing military RIW contracts for avionics units with a sample of contracts for similar items without the RIW provisions, to determine if any difference in the degree of competition existed. The variables used to measure the degree of competition were the number of contractors vying for the contract award and the variability of the proposed prices. The results of the study indicated that the degree of competition for contracts containing RIW clauses did not differ significantly from that of the contracts without RIW clauses. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Examines the Reliability Improvement Warranty (RIW). Consumer and commercial warranty experience does not alone justify optimistic expectations for RIWs; the effect of RIWs in completed Department of Defense (DOD) programs is inconclusive; and as a result of inadequate research design the expectation of drawing meaningful conclusions from the ongoing RIW experiment may be over-optimistic. Examination of completed RIW programs, however, suggests the importance of (1) modification after operational use or testing, (2) schedule flexibility, (3) contractor involvement in initial overhaul and repair, and (4) avoidance of RIWs in programs subject to extreme quantity or utilization uncertainty. The design of the DOD's ongoing RIW experiment can be improved by (1) reducing the variation in contractual terms, (2) developing better controlled conditions, and (3) establishing defined limits for the experiment. In addition, the DOD must recognize the multiple objectives of the RIW and establish priority among them to facilitate evaluation.

Lemke and published by . This book was released on 1985 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis examined the effects a reliability improvement warranty (RIW) had on the actual operational reliability of the warranted avionics equipment. To accomplish this, the most comprehensive DOD application of RIW to date, the F-16 RIW, was investigated. This study was designed to answer the question of whether or not a warranted weapons system was significantly more reliable than it would have been without the warranty. Specifically, the observed mean flight hours between failures (MFHBFs) and the observed reliability growths of the warranted F-16 equipment were compared to those of functionally similar non-warranted F-15 equipment. Also, the reliability growth of the F-16 warranted equipment was compared to that of other non-warranted F-16 equipment. The AMSAA Reliability Growth Model was used as a basis for the reliability growth analyses. Comparable life cycle time periods for each aircraft were studied, using AFM 66-1 D056 failure and flight time data. The results of the investigation indicated that, in general, the observed MFHBFs of the F-16 warranted equipment were statistically greater than the MFHBFs of the equivalent F-15 equipment. The same could not be concluded for the reliability growths of the F-16 and equivalent F-15 equipment. However, the reliability growth of the warranted F-16 equipment was found to be statistically greater than the reliability growth of the non-warranted F-16 equipment. Keywords: Air Force Planning.

Available in PDF, EPUB and Kindle. Book excerpt: The existence of a goal conflict in the buyer/seller relationship is inherent under a profit motivated system where conventional procurement techniques are used. The buyer seeks maximum performance at minimum life cycle cost and the seller seeks to maximize profit which may translate to minimizing reliability improvement costs. Experience of military and commercial procurement activities with the use of Reliability Improvement Warranties (RIW's) has led to the conclusion that the RIW may be a valuable tool in bringing buyer/seller goals into agreement by transferring the management of costs to the seller. Background material on DoD and commercial warranty experience is used to form the framework for an evaluation criteria developed by ARINC Research Corporation to test the applicability of RIW to a particular acquisition.

Available in PDF, EPUB and Kindle. Book excerpt: The Department of Defense (DOD) has only had three completed warranty programs, and data on current programs will not be complete until the early 1980s. This paper explores the reliability improvement warranty (RIW) concept by evaluating commercial analogs, past DOD warranty experience, and the current tri-service RIW trial. Examination of the completed programs does not show conclusive evidence that warranties were a major factor in observed improvement, but certain observations regarding reliability were apparent: (1) Modification after testing is needed to take advantage of field experience and can be promoted without a warranty. (2) Scheduling should be flexible to allow incorporation of test data in subsequent development and production. (3) The contractor should be involved in initial overhaul and repair. (4) RIWs should not be applied to programs subject to extreme quantity or utilization uncertainty. The authors point out that current RIW trials have terms and penalties that vary widely and diminish the likelihood that they will yield conclusive evidence on the value of warranties.

This book was released on 1979 with total page 101 pages. Available in PDF, EPUB and Kindle. Book excerpt: The reliability improvement warranty is a relatively new acquisition technique in government contracting. To encourage effective use of the technique, HQ USAF Directorate of Procurement Policy (LGP) published the pamphlet entitled Interim Guidelines Reliability Improvement Warranty (RIW) in July, 1974. This pamphlet provided guidance in the areas of application criteria, funding, provisions, determination of cost effectiveness, and general implementation and administrative information. Since the guidelines had not been revised since publication, the researchers' objectives were to determine if the guidelines were adequate and to obtain recommendations for improving those guidelines, if necessary. To meet those objectives, 24 individuals knowledgeable in the area of RIW were interviewed. Their perceptions were gathered through ten scaled response questions that addressed main areas within the guidelines. The distribution of responses were tested via the Kolmogorov-Smirnov two sample test to determine the adequacy of the area. Interviewees also recommended changes to correct perceived problem areas via open ended response questions. The researchers concluded the guidelines were inadequate in a number of areas, e.g., evaluation of candidates, example clauses, administrative concerns and cost-benefit analysis among others. Suggestions for increased detail, more examples, deeper rationale and organization into a regulation were made. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Reliability Improvement Warranty (RIW) is a type of contract that makes a contractor responsible for field-induced failures over an extended period of time. Its express purpose is to provide a vehicle for product improvement. This report presents selection criteria for RIW candidates and techniques for risk and economic analyses are developed. Three contracts are analyzed in detail with respect to RIW impact on item procurement and management. The cost effectiveness of two RIW contracts is discussed to indicate areas of probable life-cycle-cost savings to the Navy.

This book was released on 1975 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Reliability Improvement Warranty (RIW) concept is a procurement methodology which is rapidly being implemented in the United States Air Force. Effective use of this concept is contingent on expeditious movement of RIW components between Air Force bases and the contractor. Several reparable processing procedures have been used with varying degrees of success, but there is currently no established technique to aid in determining the optimum processing procedures. The authors conclude that a simulation model has been constructed which can be of assistance to the material manager and procurement officer in selecting an optimum reparable processing procedure.

Parkinson and published by . This book was released on 1983 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reliability Improvement Warranties (RIWs) were implemented by the U.S. Air Force in 1974, as the beginning of a RIW trial period. Six major Air Force programs have used RIWs since the trail period began. The Air Force Director of Contracting and Manufacturing Policy (HQ USAF/RDC) requested that the RIW trial period be concluded and that the effectiveness of the Air Force's use of RIWs during the trial period be evaluated. This research effort was an attempt to evaluate the effectiveness of RIWs during the trail period and to provide recommendations for the future use by the Air Force of the RIW concept. RIW experts involved with each of the six Air Force RIW programs were interviewed and asked to rate eleven RIW effectiveness criteria, and to provide recommendations for the future use of the RIW concept. In addition, the RIW experts were asked to respond to open-ended questions of interest to the research effort. The research team concluded from the nonparametric statistical tests the RIW experts perceived effective, and that the experts recommend continued use by the Air Force of the RIW concept. (Author).
