Aeritalia's experience pertaining to carbon composite structures going back to the early 70's when curing of lab.scale carbon composites was started followed by experimental G 222 spoilers. Aeritalia's knowledge was built-up on several programs. An important step came from the participation to the Boeing B 767 program. Aeritalia's involvement in the development work was ample and essential to the utilization of carbon/epoxy in the program. The production phase, which is still going on, gave Aeritalia a deep experience in the area of large C./EP. components fabrication and assembly and contributed to the development of both engineering and production knowledge that, combined with internal research activity, have given Aeritalia a leading position in the area of advanced composite structures. This experience was completed and further enhanced through the development of Aeritalia ATR 42 program and participation to the MD 80 and Rohr CFM 56-5 programs, which have given Aeritalia a widely recognized knowledge of the state of the art technology for C./EP. aerospace structures.

The study task was to develop a methodology for evaluating the relative utility of Naval shipyards in terms of cost and effectiveness. Phase I was a review of existing models and data, and selection of a model. The conclusion of Phase I is that no model can be found which will satisfy the requirement. Four possible models were investigated. The first two, a scheduling-cost model and a linear programming model were rejected because an essential element, a measure of shipyard productivity, is not available. LMI does not believe the construction of a measure of productivity for detailed models is practicable for several reasons: (1) the nature of overhaul and repair work (that is, it is large and complex, few jobs recur regularly and, when they do, work content varies widely); (2) the many constraints on shipyard operation; and (3) the differences among the shipyards themselves. The 3rd and 4th models, total cost comparison and fixed cost analysis, assume invariant productivity. The total cost model was found to discriminate inadequately between costs of new construction in private and Naval shipyards. The difficulty in finding comparable work packages in overhaul and repair work, the primary mission of Naval shipyards, suggests that that model would be even less useful. The fixed cost analysis assumes that there are fixed costs of operating a shipyard that would be avoided by closing a yard. However, LMI can find little to support that assumption. There is no clear evidence that fixed costs are large enough to offset the costs of closing a yard.

This thesis presents a non-technical analysis of the utility and validity of modern war gaming procedures for evaluating military plans and operational concepts. Selective contemporary applications of war gaming methodologies are investigated and their capabilities and limitations are identified and examined. The conclusion is reached that the war gaming process provides a meaningful and viable method for combining military expertise with modern analytic techniques to assist defense planners and decisionmakers in making rational choices among complex alternatives. Recommendations for improvements in the state of the war gaming art are made. (Author)

As part of the on-going research program in 'Decision Control Models in Operation Research', this paper has investigated the behavior of multi-person organizations facing risky investment decisions, such as expenditures on research and development. The path-breaking analysis examines the impact of several different organizational designs, with their implied means of decentralization. The work also focusses on the impact of limited information and the way that it is shared among decision makers. The mathematical approach adapted in the paper enables one to determine fundamental insights about organizational structure within a general framework that permits comparative analyses.

The present report explores the organizational development uses of survey data. In form, the problem is one of testing the feasibility of developing an instrumented prescriptive capability for organizational development activities in the Navy. The strategy involved: (1) Determining whether there are relatively few 'pure' types of groups present in the civilian data bank which accompanies the Survey of Organizations questionnaire (the parent instrument of the Navy's Human Resource Management Survey); (2) determining (from the Navy data collected in the course of this Present contract) the extent to which these pure types exist in the Navy as well; and (3) examining the effect of different development activities upon the pure types thus identified.

Thhe Administrator of the National program and Space Administration has established a technology utilization program for "the rapid dissemination of information . . . on technological developments. . . which appear to be useful for general industrial application." From a variety of sources, including NASA Research Centers and NASA contractors, space-related technology is collected and screened; and that which has potential industrial use is made generally available. Information from the nation's space program is thus made available to American industry, including the latest developments in materials, processes, products, techniques, management systems, and analytical and design procedures. The tooling concepts described herein are a direct result of techniques developed within the Astrionics Laboratory of the George C. Marshall Space Flight Center.

Volume four of a five volume series on recreation at reservoirs presents a general methodology for determining the number and type of facilities needed to serve a given number of reservoir recreation days of use. It is a method synthesizing planner judgment, existing recreation use data, and the concepts of estimating annual recreational use employed by the Corps of Engineers. The data utilized were collected at 52 reservoirs over the period 1966 through 1969. (Modified author abstract), See also Volume 5, AD/A-000 652.

Volume five of a five volume report presents refined procedural guidelines for estimating reservoir recreation use and benefits for planning of water resources developments. The general planning model described and tested consists of the development of regional estimators for predicting recreation use at proposed reservoir projects and the operation on these estimators to derive the individual project demand schedules for estimating recreation benefits. The methodology presented is theoretically and empirically more precise than estimating procedures currently employed and is consistent with other existing and proposed authoritative standards for evaluating water resource developments.

Volume two of a five volume report on recreational water use presents methodology for estimating the initial use at prospective Corps of Engineers reservoirs. The procedure described utilizes the most similar project concept; i.e., an existing reservoir that is most comparable in size, operation, and anticipated recreation-use characteristics. Relating recreation-use information from an existing reservoir to a reservoir under study provides the basis for the use estimating technique.

The report covers the evaluation of the Omega Navigation System for aircraft utilization on routes traversing the North Atlantic from the East coast of the United States to Europe. The user equipment was a commercial version of the AN/ARN-99 which is an automatic computerized Omega receiver designed for airborne use and was installed on a DC-8 type aircraft. The principal areas of interest in this evaluation were operational utility, signal reliability and track comparison with other aids available. The Omega system demonstrated its ability to provide smooth bounded position information in a varying and somewhat limited signal environment due to a transitional transmitter configuration.

A small (0.2 inch diameter), fast-response pressure transducer has been developed for measuring shock-interaction induced transient pressures. Transducer design incorporates the Pressure Bar principle to minimize reflections at the boundaries of the sensing element and a unique orifice-cavity method to isolate the sensing element from the external disturbances. Calibration and wind-tunnel shock-interaction data show that this type of transducer is suitable for measuring pressures of 1/20- to 100-psi magnitude and of 1- to 17-microsecond duration. Transducer performance, design and construction are described. (Author)
