TECHNIQUE USED IN DETERMINING FIELD OPERATIONAL RELIABILITY.
Abstract
The report depicts several of the problems involved in conducting an investigation to determine the operational reliability of an Army radio set utilized under actual field conditions. A reporting form was distributed to the troops prior to the exercise commencement. The form was designed to require little time for its completion and yet yield sufficient information for meaningful analysis. Three different monitoring techniques were studies to determine which would provide the most accurate and informative data with the manpower and facilities available. The technique employed was to visit each operating site twice daily, checking the reporting form against the operator's daily log; in the event of a system failure occurrence, interview both the operator and maintenance man, recording all data pertinent to the failure. Due to the lack of manpower, accurate maintenance information could not be obtained after failed equipment was sent from the operating site. Analysis of the data revealed the presence of a bias. The equipment had been used regularly at least several months prior to the exercise commencement, however, approximately thirty percent of the failures occurred in the first 420 hours. Potential causes of this bias are discussed in the body of the report. (Author)
