It realizes valid and dynamic route finding in openTCS 5.0.0.
有几位网友关于拙作《改造OpenTCS之如何避免无效路由of基于OpenTCS的二次开发实践》、《改造OpenTCS之动态更新路由of基于OpenTCS的二次开发实践》留了言，笔者以本文、已上传到github的项目openTCS-5.0.0-ValidDynamicRoute，以及视频《有效路由的动态生成与更新体验》作为回应.
笔者的相关开发在以下环境中进行.

注：加载tn-demo-lb-1234.xml、持久化到内核并进入操作模式后，可以执行分四种情形测试：
始终预订车辆：
./2-tn-demo-lb-1234-create-to-part1.sh
./3-tn-demo-lb-1234-create-to-part2.sh
始终不预订车辆：
./4-tn-demo-lb-1234-create-to-nv-part1.sh
./5-tn-demo-lb-1234-create-to-nv-part2.sh
先预订车辆后不预订车辆：
./6-tn-demo-lb-1234-create-to-part1.sh
./7-tn-demo-lb-1234-create-to-nv-part2.sh
先不预订车辆后预订车辆：
./8-tn-demo-lb-1234-create-to-nv-part1.sh
./9-tn-demo-lb-1234-create-to-part2.sh
以下对相关文件逐一描述.
这是测试用的交通运输网模型文件，其改编自openTCS官方自带的0.0.3版的Demo-01.xml；其中，车4辆、进货位3个、出货位2个、储货位2个、工作站3个、充电兼泊车位4个.
以下是对车辆Ve0001的主要描述:
<vehicle name="Ve0001"

energyLevelGood="90"
energyLevelFullyRecharged="95"
energyLevelSufficientlyRecharged="45"

<property name="loopback:initialPosition" value="2"/>
<property name="loopback:loadOperation" value="Load cargo"/>
<property name="loopback:unloadOperation" value="Unload cargo"/>

<property name="tcs:preferredParkingPosition" value="2"/>
<property name="tcs:preferredRechargePosition" value="Re01"/>
</vehicle>
派发器配置中, 为重新寻路触发器加入相关配置项.
