QUESTION 2 Your company plans to produce a toy with a total of 296,000 units per year. As an engineer, you are required to design the assembly line which operates at 8 hours per shift, 2 shifts per day, 5 days per week and 50 weeks per year. Assume 98.66% of uptime efficiency. The assembly line operates with a mechanized conveyor. The repositioning time is 6 sec. Fourteen (14) work elements must be accomplished to complete the assembly. The element times and precedence requirements are listed in the Table Q2.
