The Optimization Of Drip Pipe Network In Different Shapes Field

The paper mainly researches the optimization of drip field network of different shapes block. Firstly, it adopts orthogonal principle, partition method, making-up method and experience to arrange the network with reasonable layout; and then it uses Genetic Algorithm which based on integer coding to optimize the pipeline's diameter. And programs for the optimization of the pipeline's diameter with C++, it achieved design experience and computer technology's combination and avoided the limitations caused by a single method. The article not only optimized the familiar terrain's (rectangular) field network, but also simplified the irregular terrain which often encountered, and then optimized it, resolved the optimization problems of drip pipe network in different shapes field. It mainly includes some parts content as follows:1. It puts forward the optimized layout methods for drip field network of different shapes block. Combines the network optimization principle for drip field of regular terrain, and then puts forward network layout methods for irregular terrain and bases on which set up model for drip field network.2. We adopt hydraulic knowledge to set up model for different shapes block. When we set up model for irregular block, firstly, we simplified it to terrace which we familiar, and then combined the rectangular optimization method, using partition method and making-up method to optimized it separately, educed the cheapest one finally.3. Genetic Algorithm which based on integer coding to code the pipeline's diameter, it will often lead to redundant encodings. In order to avoid the defects effectively, the paper adopt GA , which based on integer coding.4. Programmed computer program based on integer coding GA and combined the former methods about field network layout, such as orthogonal principle, typical layout plan, partition method and making-up method. It achieved design experience and computer technology's combination and avoided the limitations caused by a single method.
