The invention discloses a tank field oil transportation operation scheduling optimization method and belongs to the computer auxiliary manufacturing field. The method comprises steps that a, the information of a crude oil tank field and the product oil tank field equipment is collected, and basic tank, valve, pump and pipeline attribute configuration is carried out; b, the production data is written into a remote terminal unit, the data is read by a data acquisition server from the remote terminal unit, and the data is written into a database; c, the real-time production data is read, each tank, valve, pump and pipeline use state is determined, and the information is written into the database; d, a connection relationship of the tank field equipment is taken as a base, in combination with an available state of each equipment and constraint conditions, multiple optimized operation lines are acquired through automatic inference; and e, a proper scheduling operation line is selected by scheduling staff, the selected scheduling operation line is submitted to management staff for check, after an operation flow is checked by the management staff, the operation flow is carried out online. The method is advantaged in that a tank field oil transportation operation scheduling instruction can be optimized, oil transportation operation scheduling errors can be further reduced, and work efficiency is improved.
