For Problem 17.24, determine the variable rate launching intervals for models A and B.
Problem 17.24
Two product models, A and B, arc to be produced on a mixed model assembly line. Hourly production rate and work content time for model A are 12 units/hr and 32.0 min, respectively; and for model B are 20 units/hr and 21.0 min. Line efficiency E = 0.95, balance efficiency Eb = 0.93, repositioning time Tr = 0.10 min. and manning level Al = 1. Determine how many workers and workstations must be on the production line to produce this workload.
