In this paper, influencing factors and decision criteria of allocating non-safety DCS functions are analyzed and discussed. A top-to-bottom hierarchical allocation model is proposed to balance the independence while taking into account the relevance of functions, reduce the interdependence of processors as well as data exchanges, and evenly distribute workloads in a DCS, which ultimately reduces the impact on the availability of a nuclear power plant in case of a DCS failure.
