Human Resources Sensitivity to System Design Tradeoff Alternatives: Feasibility Test with Jet Engine Data.
Abstract
The feasibility of developing design option decision trees to a level of detail which shows hardware involved in 'on-aircraft' maintenance, and the feasibility of measuring the sensitivity of human resources data to design tradeoff problems depicted in these trees were investigated. The approach included expanding a portion of an earlier developed aircraft jet engine tree, selecting tradeoff problems from the expanded tree for sensitivity analysis, and collecting psychometric data from experienced jet engine mechanics regarding this sensitivity. Five design option decision trees were developed for turbofan jet engines. Eight turbofan tradeoff problems were evaluated for affect on human resources. The factors of training and experience, and amount of troubleshooting time are affected by choice of design option in six of the eight tradeoff problems. Ease of maintenance is affected in five problems, and complexity of tools and equipment is affected in two problems. Crew size and job specialty are each affected in one problem. (Author)
