Solution of Steel Pipe Splicing with Improved Invasive Weed Algorithm(IWA)

Addressing the problem that manual generation of the splicing scheme has shortcomings like wasting manpower and material resources,the improved invasive weed algorithm (IWA) method is employed to solve the issue of steel pipe splicing.After analyzing the demand for steel pipe splicing,related mathematical model is set up.Furthermore considering the drawbacks staying with actual engineering application of the IWA method such as over close connection with the initial position, and over concentrated optimization process, which fails to realize the global research,the improvement is conducted from two aspects,i.e.,the initial position and the diffusion calculation so as to simplify the issue from steel pipe splicing into a issue of constrained minimal value solution.The actual application result shows that the said improved IWA method is capable of well optimizing the steel pipe splicing.
