Transportation Reliability Model of Package Products

摘要

A reliability model of packaged products in transportation has been built in ter ms of a generalized shock assumption. Shocks acting on products are assumed to c ome from an unexpected source following Poisson stochastic process in which each shock has a standard normal distributed response acceleration, and the transpor tation package reliability is defined as the probability that within a given tim e period, the maximal response acceleration on the packaged products does not ex ceed a specified value, i.e. fragility of the products. A formula of the transpo rtation package reliability is deduced and a numerical example is presented to i llustrate the results. If packaging designers could follow the results given in the paper, packaged products could achieve minimum packaging cost while guarante e delivery safety without causing damage or quality loss.
