为控制蘑菇种植过程中尖眼蕈蚊数量,利用线虫和尖眼蕈蚊数量变化的动态关系模型,应用分布估计算法对控制干涉次数和控制数量进行优化处理,将其与遗传算法结果进行比较。结果表明:该算法在控制次数略有增加情况下,可以取得较小目标函数值,并且算法稳定收敛,该结果可以作为一种理想的控制优化方案。分布估计算法可以用来处理此类动态关系模型的优化问题。

This paper presents an analytical approach for estimating frictional resistance to pipe movement at soil and external pipe surface of buried coated pressurized steel pipes relative to the internal thrust *** proposed analytical method was developed based on 36 experiments,which involved three coating types(cement mortar(CM),polyurethane type-I(PT-I),prefabricated plastic tape(PPT))on pipes’surfaces,three different soils(pea-gravel(PG),sand(S),silty-clay(SC)),and four simulated over burden depths above the pipe’s *** showed frictional resistance decreased with increasing over burden depth above the pipe’s *** degree of frictional resistance at the pipe-soil interface was found to be in the order of PG>SC>S for all coating variations and overburden *** coated pipe buried in all three types of soil produced significantly higher frictional resistance as compared to other coating *** on experimental data,the developed analytical introduced a dimensionless factor“Z”,which included effects of types of coatings,soil,and overburden depths for simplified rapid *** showed that the method provided a better prediction of frictional resistance forces,in comparison to previous analytical methods,which were barely close in predicting friction resistance for different coating variations,soil types,and overburden *** resistance force values reported herein could be considered conservative.
