QUESTION V. The demand for product X produced by a firm has been 100 units. This X product consists of 3 sub-parts ( A,B,C), and the product tree is given in the figure below. The values given in parentheses in the figure represent the required part quantities for 1X product. The route information, error rates (\%), preparation and processing times of the 3 pieces seen in the product tree are given in the table below. When the production of parts A, B and C is completed, these three parts are assembled. Table. Route and time information for parts of product X In the workshop of the company, there are 2 planers, drilling benches and 1 cutting, turning, milling and bending machines with the same features. Although there is no difference according to the type of part in the planer bench, a maximum of 55 parts can be produced at a time. When the production of 55 pieces of any piece is completed, the preparation processes are carried out again on the planing bench. Transport times between machines are neglected. A piece is not sent to another machine until the entire production (lot) on one machine is completed. In cases where the capacity is insufficient, a maximum of 4 hours of overtime is allowed for all benches in one shift. According to the principle of finite capacity loading, calculate the total production time of each part of the product X in each workbench, and make a scheduling study in a way that does not exceed the workload of all benches according to the working style of 2 shifts ( 8 hours per shift). Find the total overtime hours required to complete 100 pieces of X products in 5 days
