Problem 2: (10 Points) Suppose there is an order for 200 of gear shaft SG 123. The due date is day 158. The route sheet, shown in Figure 1. gives information about the operations to be performed and the setup and run times. The work center file, shown in Figure 2 gives lead time data for each work center. Calculate the start and finish dates for each operation. Use the following scheduling rules. a. Operation times are rounded up to the nearest 8 hours and expressed as days on a one-shift basis. That is, if an operation takes 6.5 standard hours, round it up to 8 hours, which represents one day. b. Assume an order starts at the beginning of the day and finishes at the end of a day. For example, if an order starts on day 1 and is finished on day 5, it has taken 5 days to complete. If move time is 1 day, the order will be available to the next workstation at the start of day 7.
