Question

DO NOT COPY THE ANSWER FROM ANOTHER SIMILAR QUESTION!!! IT IS INCORRECT!!!!

A new electrical device is to be assembled in the new facility.The line will be operated 250 day/yr, 15 hr/day. The work content has been divided into work elements as defined in the table below. Also given are the element times and precedence requirements. Annual production is to be 400,000 units. It is anticipated that the line efficiency (proportion uptime) E = 0.97. The repositioning time for each worker is 0.06 min. With an average hourly production rate of 106.67 units, cycle time of 0.5456 mins, service time is 0.4856, and theoretical minimum number of workers is 17.48 rounded to 18.Balance the line and determine the efficiency (balance) and overall labor efficiency of the line. Use the Ranked Positional Weight Method.

Again, DO NOT COPY THE WRONG ANSWER, when making the workstations you sum of telemnet times cant go over the service time 0f 0.4856. Meaning Workstation 1 does not have element 1, 2, 4, and 3 suming up to 0.94 becuase that is over 0.4856 and is THE WRONG ANSWER!!!!!!

Element # Time (mins) Preceded by | 0.15 0.37 0.21 0.21 0.58 0.12 0.29 0.12 0.30 0.45 0.18 0.20 | Element # Time (mins) Preceded by 0.65 0.72 0.25 0.35 0.16 0.12 0.10 0.23 0.40 0.33 0.25 1.75 6,7,8,9 10,12 16 17 18 19 20 21 1,2 15,16 18,19 17,20 21 4,5 10 23 24 12 23
