Some Results from Applying a Cost-Effectiveness Model for Evaluating Aviation Weather Dissemination Techniques.

摘要

Some results were obtained from a cost-effectiveness model which was developed for evaluating the performance of various combinations of aviation weather dissemination techniques. Basic data on which the model operates consist of distributions of registered general aviation aircraft,air traffic activity and total flight services,FAA forecasts of growth in general aviation during the next decade,and the cost of various dissemination techniques and facilities. These data are used to generate estimates of demand in a 26 x 60matrix of 1degree squares covering the 48states. Dissemination technique effectiveness values are arrived at largely through two factors--accessibility and usefulness--which were obtained via a Delphi approach. As part of the model's output,measures of system performance are given in terms of percentage of demand satisfied by the total system,each technique,and each portion of the flight profile. Computations give cost-per-demand served,cost of the total system plus overhead,and the cost of each technique in terms of capital,operating,and personnel costs. (Modified author abstract)
