An Agvs Will Be Used To Satisfy Material Flows Indicated In The From To Chart In

An AGVS will be used to satisfy material flows indicated in the from-to Chart in the table below, which shows deliveries per hour between stations (above the slash) and distances in meters between stations (below the slash). Moves indicated by “L” are trips in which the vehicle is loaded, while “E” indicates moves in which the vehicle is empty. It is assumed that availability = 0.90, traffic factor = 0.85, and efficiency = 1.0. Speed of an AGV = 0.9 m/s. If load handling time per delivery cycle = 1.0 min, determine the number of vehicles needed to satisfy the indicated deliveries per hour? Assume that availability = 0.90.
