Abstract: To ensure safety for process systems, a safety resource allocation and optimization method based on dynamic planning was proposed. Firstly, by analyzing system safety, the feature parameters for safety evaluation and the computation methods for the parameters were determined. Then, the process of the resource allocation and optimization was performed by taking the inherent network structural model of process system as the investigation object and introducing the safety feature parameters as well as adopting the optimal principles of stepwise refinement of dynamic programming. This proposed method could satisfy the constraints of the limited investment quantity and the maximize safety improvement; and then, the weaker sections were prior allocated. Finally, an example on the resource allocation and optimization for process system safety was used to reveal its feasibility and effectiveness.
