A robot is used for loading and unloading of parts to automated flexible machines. Loading time is 1 minute; unloading time is 1.5 minutes; machining time 15 minutes; Robot travel time between the machines including the inspection time is 3 minutes. Cost of robot C,=30 TL/Hour; cost of machines C2=40 TL/Hour. How many machines (integer number) should be assigned to the robot so that the total robot and machine costs per cycle are minimized? 8 - 176 a) 4 b) 3 c) 2 d) e) 6.

The BOM for product A is shown in Figure 11.40, and datafrom the inventory records are shown in Table 11.9. In theMPS for product A, the MPS start row has 100 units in week 3and 200 in week 6. Develop the material requirements planfor the next 6 weeks for items C, D, and E.a. Develop the material requirements plan for the next6 weeks for items C, D, and E.b. What specific managerial actions are required inweek 1?

A batch of 35 parts is ordered by a customer about every six months. The parts are currently processed sequentially through five conventional machines, listed in the following table with setup times and work cycle times per piece. These machines all require an operator to be in attendance during the work cycle. There is a delay of 10 hr/machine dueto transport between machines and waiting in queues of other parts processed by thesemachines. A recommendation has been made to process the parts on a new multitaskingmachine that would complete the batch in one setup, which would involve a simple fixtureand a setup time of 2.0 hr. The work cycle on the multitasking machine consists of thesame operations that are accomplished by the five machines, but the cycle time would beless than the sum of the five cycle times by one-half because of tool path improvementsand reduced part handling. Determine the manufacturing lead time (how long it takes tocomplete the batch of 35 parts, including…

A toy manufacturing uses 51030 rubber wheels per year for its popular dump truck series. The firm makes its own wheels, which it can can produce at a rate of 800 per day. The toy trucks are assembled uniformly ( at a constant rate ) over the entire year. Carrying cost is $ 1.50 per wheel per year. setup cost for the production run of the wheel is $ 47. The firm operatyes 243 days per year. Determine each of the following: 1-Optimal run size 2-Use your final answer from part 1 to determine minimum total annual cost for carrying and setup 3-Cycle time for the optimal run size 4-Run time

A very special manufacturing operation is being designed as an assembly line. Table 1 shows the tasks that need to be performed, their task time, and preceding tasks. The goal is to produce 5760 products per month. The company has an operation pattern of 24 days per month with 8 hours per day.   Draw a precedence diagram. Determine the cycle time. Using the largest work element-time rule, assign tasks to the workstations in order to have appropriate line balancing. Identify the idle time for workstation 1, 2 and 6. Identify the number of workstations for the balanced line. Calculate the balanced line effieciency to 2 decimal places (Example 0.78).

Using the information in the task list, calculate the duration of the project.  Station 1 Processing time:5 min--> station 2 processing time 3 min--> station 3 processing time 2 min --> station 4 processing time 6 min
