Abstract: The multilevel handlings delay occurs frequently in uncertain environments at automated container terminals (referred to as automated terminals). The delay will propagate among the multiple handlings over time, resulting a "chain" effect that will have a significant impact on the overall efficiency of the port. To improve the ability of enterprises to cope with handlings delays, a multilevel handlings hypernetwork is constructed based on the theory of hypernetwork and propagation dynamics. Combined with the topology characteristics of the small-world network theory, the propagation speed, propagation breadth, and propagation capacity of delay in multilevel handling hypernetworks are discussed and numerically simulated from three perspectives: characteristic path length, clustering coefficient, and SIS simulation. The results show that the shorter characteristic path length and larger clustering coefficient will make the delay propagated more quickly and widely, the fault nodes with smaller clustering coefficients will be restrained by clustering characteristics. The network's propagation capacity is directly proportional to the initial fault nodes' number and inversely proportional to the repair probability. This study is beneficial for enterprise managers to actively respond to the delay caused by uncertain events and improve the operation efficiency of ports.
