It aims at finding the program that economically meets the technology requirement. However, the system engineering needs enormous calculations and works. The use of software can not only highly raise the efficiency, but also calculate the parameter accurately in intuitionistic way, consequently achieve the optimization of pipeline. This paper first gives a overall summary of mathematical models of optimal design, optimumseeking techniques and their development trends and the optimization researches in pipeline project. According to the theory of hydromechanics and heat transfor, the author build the mathematical model for the optimal design of pipeline system transporting hot waxy crudes, then design the software for optimezation of pipeline base on the mathematical model in visual basic language. The software use Microsoft Office Access as datebase, which was linked by ADO control, then dates were showed in the form by date grid main functions of the software are date inputing, calculating temperature and pressure and drawing their graphs, calculating time of halt and optimal parameter. The calculations of the pipeline which is from Bai bao to Hua che indicate that the results accord with practical parameter, consequently achieve the optimezation of , the reliability and practicability of the software is is especially significant for improving the design and management arts of petroleum pipeline to the solution of the problem.
