Rail transit passenger flow control and large and small intersection opening scheme collaborative optimization method

The invention relates to a rail transit passenger flow control and large and small intersection opening scheme collaborative optimization method, and belongs to the technical field of supply chain management. The method comprises the following steps: step 1, proposing three hypotheses according to a problem: hypothesis 1: the train types and marshalling modes are the same, and large and small cross-road trains stop in a cross-road range; assumption 2: the passenger service process follows the principles of'first-in first-out 'and'first-down first-up'; assumption 3: under the condition that the large and small intersections are opened, passengers take the train which arrives at the station first; step 2, collecting, processing and counting basic input data; step 3, establishing a rail transit passenger flow control and large and small intersection opening scheme collaborative optimization model; step 4, processing a nonlinear relational expression in the optimization model; and step 5, solving the proposed rai
