A work sampling study was conducted on a worker-machine system to establish the standard time for an automotive brake module assembly. The study took 3 standard 8-hour shifts to complete. The machine allowance factor is assumed to be zero. A total of 160 observations had been made and the summary of the study is listed below. Manual operation Machine controlled operation Machine idle time Average performance rating Number of modules produced Allowance for personal needs and fatigue = 14 minutes = 106 minutes = 40 minutes = 80% = 36 units = 10% (i) Determine the average task time to produce a brake module in machine-controlled operation and in manual operation. (ii) Determine the normal time to produce a brake module for the assembly operation. (iii) Determine the standard time to produce a brake module for the assembly operation
