Abstract: Business process is a hot topic in enterprise management, application and integration, and business process modeling is one of the key points in the application of business process. The paper presented a lane-based optimization modeling to the low degree of automation for process modeling and the lack of effective evaluation. hhis method can automatically model the whole business process graph according to the activities' extrapolation on the premise that the description of activities in every process is given. Then a lane process graph levelly for the possible process was made. At last, the execution cost and lane equilibrium were integrated, the best one from the leveled lane models was selected as the final business process. Combining the genetic algorithm, the author modeled the container business process. The applications show that the business process built using this modeling can effectively balance the business load and improve the operational efficiency.
