Answer:
Balance delay is the percentage of wasted time calculated as 100% - efficiency. on the line is 0.085 or 8.5%
Step-by-step explanation:
Given details
numbers of workstations (n)= 25
manning level = 1.0
work content time (Twc) = 29.5 min
production rate = 40 units/hr
proportion uptime = 96% = 0.96
repositioning time = 9 sec.
balance delay = ?
Solution
Cycle time (Tc) = 60(0.96)/40 = 1.44 min
Ts = 1.44 – 0.15 = 1.29 min
Line balance efficiency (Eb) = Twc/(n*Ts) = 29.5/25(1.29) = 0.915
Balance delay (d) is the percentage of wasted time calculated as 100% - efficiency.
d = 1 – 0.915 = 0.085 = 8.5%
