Please answer number 5 with information from question 1
- A worker-machine cycle is direct time studied using the continuous timing method. One part is produced each cycle. The cycle consists of five elements: a, b, c, d, and e. Elements a, c, d, and e are manual elements, external to machine element b. Every 16 cycles the worker must replace the parts container, which was observed to take 2.0 min during the time study. All worker elements were performance rated at 80%. The PFD allowance is 16%, and the machine allowance = 20%. Determine (a) the normalized time for the cycle, (b) the standard time per part. (c) If the worker completes 220 parts in an 8-hour during which he works 7 hours and 12 min, what is the workers efficiency? (20pt)
| Element | Description | Cumulative observed time(min) | |
| a | Worker loads machine and starts automatic cycle. | 0.25 | |
| b | Machine automatic cycle | 1.50 | |
| c | Worker unloads machine. | 1.75 | |
| d | Worker files part to size. | 2.30 | |
| e | Worker deposits part in container. | 2.40 |
5. In the preceding problem, a recommendation has been submitted for elements d and e to be performed as internal elements (accomplished simultaneously) with machine element b. The worker would file the part from the previous cycle and deposit it in the container while the current part is being processed in the machine automatic cycle. Performance rating and allowances are the same as in the previous problem. Determine (a) the normal time for the cycle, (b) the standard time per part. (c) If the workers efficiency is 115% and he works a total of 7 hours and 12 min during an 8-hour shift, how many parts will be produced?
