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...
