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.

ILLUSTRATION 2: An operator manufactures 50 jobs in 6 hours and 30 minutes. If this time includes the time for setting his machine. Standard time allowed for the job was: Setting time = 35 min Production time per piece = 8 min %3D

Q1. A power-shift crawler tractor is excavating hard materials of earth (clay) and pushing it a distance of 100 ft. The hourly cost of a power-shift crawler tractor is $200. Maximum reverse speeds are: first range, 6 mph; second range, 9 mph; and third range, 11 mph. Rated blade capacity is 18 LCY. Estimate dozer production if the job efficiency factor is 50 min/hr and what is the expected unit cost for dozer work ($/BCY)?

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 production process at Kenneth Day Manufacturing is shown in the figure below. The drilling operation occurs separately from, and simultaneously with, the sawing and sanding, which are independent sequential operations. A product needs to go through only one of the three assembly operations (the operations are in parallel). 2.1 units/hr Sawing 7 units/hr Sanding Drilling 6 units/hr Welding 2.5 units/hr a) Sawing is the bottleneck. b) The bottleneck time is 28.57 minutes per unit (round your response to two decimal places). c) The throughput time of the overall system is minutes (round your response to two decimal places). Assembly 0.8 units/hr Assembly 0.8 units/hr Assembly 0.8 units/hr

Task 1: 1. The quantity of sandwiches, Q, made in a small coffee shop is given by the equation Q = -2L³ +12L? where L is the number of labour-hours hired. (a) Write down the equations for the marginal product of labour (MP1) and average product of labour (APL). Give a verbal description of MP1 and APL at L = 1.5. (b) Calculate the units of labour at which MP1 and APL are maximised, and plot both graphs on the same diagram. Confirm algebraically that MPL and APL are equal when APL is at a maximum. (c) Find the turning points and point of inflection for the production function. Plot the pro- duction function. (d) Use the graphs and any other results calculated in (a) and (b) to describe how productivity (Q= number of sandwiches) and the rate of change in productivity as the number of labour units employed (L) increase. Is there any relationship between the turning points and points of inflection in the graphs plotted in (b) and (c)?
