摘要
A statistical model to estimate the probability of slip and fall incidents is presented. In estimating such an event, the available friction is usually compared with the required friction for the activities. In the models available in the literature, only mean values were compared or a minimum threshold was used to represent the required friction. In the current model, it is assumed that both the available and required friction coefficients have stochastic distributions. Formulations for a general distribution were developed and are presented. The results generated with the current model are compared with those based on other models using a normal distribution. The results indicate that there could be significant differences between the current model and the existing models in estimating the probability of a slip incident. (C) 2004 Elsevier Ltd.
