Chapter 3

A flow line mass production operation consists of eight manual workstations. Work units are moved synchronously and automatically between stations, with a transfer time of 15 sec. The manual processing operations performed at the eight stations take 40 sec, 52 sec, 43 sec, 48 sec, 30 sec, 57 sec, 53 sec, and 49 sec, respectively. Determine (a) cycle time for the line, (b) time to process one work unit through the eight workstations, (c) time to produce 10,000 units.

Solve for:

a: Determine the longest processing operation time: ? seconds

b: Time to process one work unit through the eight workstations = ? minutes

c: Time to produce 10,000 units = ? hours

Typical cycle time for a production operation: T_c= T_o + T_h + T_t

where T_c = cycle time,

T_o = processing time for the operation

T_h= handling time (e.g., loading and unloading the production machine)

T_th = tool handling time (e.g., time to change tools)

Group of answer choices

a= 1.2 min b= 12.6 min c= 40 seconds

a= 2.2 min b= 13.6 min c = 40 seconds

a= 1.2 min b= 12.6 min c = 40 seconds

a= 1.2 min b= 9.6 min c = 50 seconds
