This study proposes a two-step game theory model framework for the purpose of scheduling police patrol shifts. In the first step, the three important factors of interaction between criminals and police are modeled as a zero-sum non-cooperative game, and the risk value of each patrol area is obtained by calculating the mixed strategy Nash equilibrium. In the second step, the Shapley values of three different threat levels are calculated according to the rates of criminal events within three time periods. Finally, the Shapley value is derived based on the three criminal threat levels for each district. A fair allocation of police personnel based on the Shapley value is made with a minimum set of personnel deployment costs. This study used the 2016 San Francisco Public Security Bureau's open data for consolidation and calculations to validate the model. The experimental results show that police planners can use this framework to quantitatively evaluate the criminal threat in each district when deciding upon the deployment of patrol officers for three shifts per day.
