Question is for my Indistrial Engineering course.

For a new product, the top management of an assembly plant decided to set up TWO new assembly lines with identical workstations. 103000 products are required every year. The assembly plant works 235 working days per year, 3 shifts per day, and 7.5 hours per shift. 14% of total time is lost due to inefficiencies. The required operations, their precedence relationships, average times, and standard deviations are in Table 1. 1aDle 1 Uperations, precedence, average assemby mmes ans sarnuatu ucvistum Operation Lrequires the use of a testing machine, Operations M,N,O,P must be done while the product is on the machine and can be done simultaneously with L. Due to this, operations L,M,N,O, and P must be assigned to the same station. To design the lines and workstations, the company decided to use the operator saturation as: the main indicator when assigning tasks to workstations. For each workstation, the following criteria must be satisfied: 0.78
