    Imprecision in decision analysis is modeled using fuzzy-set theory. Fuzziness on the probabilities and utilities used in a decision analysis implies fuzziness on the outputs; a method is suggested for calculating imprecise, though informative, statements about the attractiveness of the different options in a decision tree, which depends on the imprecision of the inputs. A general discussion of the advantages and disadvantages of the approach is given. View full abstract»

    Second-order statistical regression models are developed for the rates of demand for different types of emergency medical services (EMS) as they relate to various socioeconomic, demographic, and other characteristics of a service area. The model parameters are estimated by the recent technique of ridge regression, which is shown to provide superior estimates to those of the ordinary least squares regression method, because of the presence of substantial multicollinearity (nonorthogonality) in the exogenous data set. The ridge results are also compared with those derived from a related Bayesian approach. The resulting models provide substantial fits to the empirical data for the EMS system of the city of Atlanta, GA. View full abstract»

    Digital techniques for detecting changes between two Landsat images were developed. A data matrix containing 16 × 16 picture elements was used for this purpose. The Landsat imagery data was corrected for sensor inconsistencies and varying sun illumination. The Kolmogorov-Smirnov test (K-S test) was performed between the two corrected data matrices. This test is based on the absolute value of the maximum difference (Dmax) between the two cumulative frequency distributions. The limiting distribution of Dmax is known; thus a statistical decision concerning changes can be evaluated for the region. The K-S test was applied to different test sites. It successfully isolated regions of change. The test was found to be relatively independent of slight misregistration. View full abstract»

    The ability of operators to detect step changes in the order of control dynamics is investigated as a joint function of a) participatory mode, whether subjects are actively controlling those dynamics or are monitoring an autopilot controlling them, and b) concurrent task workload. Five subjects either tracked or monitored the system dynamics on a two-dimensional pursuit display under single task conditions and concurrently with a "subcritical" tracking task at two difficulty levels Detection performance was faster and only slightly less accurate in the manual as opposed to the autopilot mode. Performance in each mode was derogated by the concurrent tracking requirement, but not by increases in loading task difficulty. Further analysis indicated that manual superiority was attributable to the additional proprioceptive information resulting from operator-control adaptation to the system change. View full abstract»
