某城区有 36 个垃圾集中点，每天都要从垃圾处理厂（第 37 号节点）出发将垃圾运回。现有一种载重 6 吨的运输车。每个垃圾点需要用 10 分钟的时间装车，运输车平均速度为 40 公里／小时（夜里运输，不考虑塞车现象）；每台车每日平均工作 4 小时。运输车重载运费 1.8 元 / 吨公里；运输车和装垃圾用的铲车空载费用 0.4 元 / 公里；并且假定街道方向均平行于坐标轴。请你给出满意的运输调度方案以及计算程序。-City have a focal point 36 of refuse every day from the waste disposal plant (node No. 37) returned from the litter. A current load of 6 tons truck.
