摘要

An analytical method for predicting thc optimum number, location, and signal sound level of auditory warning devices is proposed. Factors which influence the perception of alarm signals, namely, ambient sound level, machining workstations(locations and their generated sound levels), workers' locations, and recommended signal sound level reaching workers are considered in the development of the objective function and constraints. Solving the multiple alarm location problem with a nonlinear programming technique yields the minimum number of auditory warning devices, their locations, and the minimum required sound level of warning signals. Two examples are given to demonstrate the applications of the predictive model.
