AGV utilization with FCFS dispatching
Assuming the transfer station in Figure 10.59 b is labeled station 9, consider the zone defined by stations \{1,6,7,8,9\}. Suppose two job types (labeled A and B) are handled through this zone. Assuming that stations 1 and 9 serve as I/O stations for the zone, suppose the average hourly production volume and the production route for the two job types are given as follows: job A: 6 jobs per hour (1-7-9); job B: 9 jobs per hour (9-6-8-1). The resulting from-to flow chart (including the \Lambda and \lambda values) is shown in Figure 10.60 a.
