Lab Assignment A manual assembly line is to be designed to make a small product. The work elements, their time and the precedence constraints are as follows: Element Time(min) Preceded by 1 0.4 2 0.7 3 0.5 4 0.8 2 5 1 2,3 6 0.2 3 7 0.3 4 8 0.9 4,9 9 0.3 5,6 10 0.5 7,8 1- Using the smallest cycle time possible, what is the optimal number of workstations? 2- What is the optimal assignment of work elements to work stations? 3- What is the resultant takt time and neck time? 4- Find the line efficiency and balanced delay 5- If it is only possible to have three work stations a- What is the optimal assignment of work elements to work stations? b- Find the line efficiency and balanced delay, did it improve
