由以上数据的分析得知

(1)如Qpark(Average=3.94 ,Util=0.986, Av_Time=3916.32 , Av_Wait=26675.88)，效率

上还可以继续提高

(2)以本模式snap3的报表为例，AGV01的Vehicles的Delivering（载Loads到目的地）的

时间花了45%，平均每一趟的时间为49.74sec,Retrieving(到Loads的所在去载货)的时间

花了49.5%的时间，平均每一趟的时间为54.66sec,Going To Park(准备要去停车)的时间花

了5.3%的时间，平均每一趟去停车的时间为11.17sec,而真正停车的时间(Parking)占了

0.2%的时间。由Vehicle Statistics的资料可大略看出Vehicle使用的状况，Retrieving

的时间很长，改善的方式为改变Vehicles数量或改变Layout的设置.

改变数量以后的数据为

由以上数据的分析得知：以本模式snap3的报表为例，AGV01的Vehicles的Delivering（载

Loads到目的地）的时间花了30.1%，平均每一趟的时间为49.89sec,Retrieving(到Loads

的所在去载货)的时间花了43.7%的时间，平均每一趟的时间为72.42sec,Going To Park(准

备要去停车)的时间花了17.7%的时间，平均每一趟去停车的时间为22.34sec,而真正停车的

时间(Parking)占了8.5%的时间。由Vehicle Statistics的资料可大略看出Vehicle使用

的状况，如AGV01，Retrieving的时间略有缩短，系统有所优化。
