Mathematical Model and Optimal Solution in Asphaltum Transportation Logistics

According to fact that unify to dispense the Sinopec's asphaltum railway tank car transportation it establishes the mathematical model which includes the minimal objective function such as total car and day, supply Excel electrical form to solve the linear programming and establishes the model of transportation problem. Simulating the tensional situiation of car supplying in midseason it establishes expansional model of transportion linear programming. According to the result of solution to adjust the tensional condition and then use quadratic programming to get the strongest traasportion ability. Based on the electrical form to set up the model and beg the solution, the author points out that it has very strong and actual extension application value.
