文摘A reliability model of packaged products in transportation has been built in terms of a generalized shock assumption. Shocks acting on products are assumed to come from an unexpected source following Poisson stochastic process in which each shock has a standard normal distributed response acceleration, and the transportation package reliability is defined as the probability that within a given time period, the maximal response acceleration on the packaged products does not exceed a specified value, i.e. fragility of the products. A formula of the transportation package reliability is deduced and a numerical example is presented to illustrate the results. If packaging designers could follow the results given in the paper, packaged products could achieve minimum packaging cost while guarantee delivery safety without causing damage or quality Ices.
