Pachira macrocarpa was the most cultivated foliage plants in Taiwan. The appearances were variable and with high plasticity. Pachira macrocarpa had a large output for export every year. However, braiding work was still in artificial, and it wasted a great deal of manpower. The standard work was not easy to quantify, and long-term work also caused occupational injury in hand. The related machinery development in this industry was lack. With changes of agricultural society structure, the braiding artificial became less with the labor shortage problem.

中文摘要马拉巴栗目前是台湾栽培最多的观叶植物，其植株造型变化多可塑性高，每年外销产量庞大，目前在编辫仍以人工方式进行，需耗费大量人力，长时间编辫亦会造成手部职业伤害，且作业标准不易量化，随著农业社会人口结构改变可进行编辫的人力也逐渐变少，常面临人力不足的情况。

The system implemented forest fire model selection automatically and intelligently. BP artificial neural network model of forest fire model selection was build by treating forest fire environment data as inputting variable and treating appropriate forest fire model as outputting variable. At the same time, we studied the methods of acquiring and calculating data of inputting and outputting. The system implemented machine of model selection automatically based on dynamic data driven technology. We selected 72 items experimental data from historical forest fire records in Beijing to experiment and confirm the validity of model selection. It turned out that the reliability of model selection is more than 80 percent.
