Filed: 2001-07-24
Abstract: PROBLEM TO BE SOLVED: To make a conveyance vehicle reach an arrival point in a short time while taking the movement of other conveyance vehicles into consideration when a movement route of a conveyance device making the conveyance vehicles move on network conveyance paths. SOLUTION: As for each route candidate, the stroke time when a conveyance path constituting the route is passed through and the turning time when a branch device is passed through are found (steps S103, S104). Then an ideal arrival time is found (step S107) by summing up stroke times and turning times up to each branch device and an actual arrival time is found (S108) by further adding a total standby time up to there. The difference between the found actual arrival time and a reservation cancel time of a branch device is found as the standby time at the branch device and added to the total standby time. Thus, the total stroke time, total turning time, and total standby time up to the end of each route candidate are found and then totaled to find a conveyance time.
