Spread model and application of shortage of supplies for emergency logistics network
Aim at the problem for how to analyze the propensity to spread of shortage of supplies in emergency logistics decision support system， this paper proposed a new model to study the propensity to spread of shortage of supplies for emergency logistics network. This paper， by the mechanism of viral spreading and introducing the parameter of time "t"， it constructed SI-SIRS (susceptible infective and susceptible infective recover susceptible) model to analyze the scale-free network which included 61 nodes. Case analysis shows that SIRS effectively depicts the spread behavior of shortage of supplies in emergency logistics network. Propensities to spread of shortage of supplies are effected by node self-spread ability， network topology， individual nodes differences and responding mechanism of emergency logistics.
