Question

A firm is designing an assembly line to manufacturing its new product. The following tasks must be performed in the sequence and time specified in the following table, for a successful production of the new product. The production line will operate for 480 minutes (8 hours) per day and the forecasted demand is 600 units per day.

Task	Task Time (Seconds)	Immediate Predecessor
A	32	None
B	30	None
C	10	A
D	42	B, C
E	25	C
F	20	D, E
G	15	E
H	25	F, G

Draw a precedence diagram for this set of tasks.

Calculate the cycle time for this production line.

Calculate the theoretical minimum number of workstations required.

Balance the line by completing the following table. When assigning tasks to workstations, use “with most followers” as your primary rule and
“with longest task time” as your secondary rule to break any ties.

Note: the table above does not indicate in any way the number of workstations the right answer should have. It is just to provide you with the overall format of the table necessary to solve the problem.

Calculate the efficiency of your line balance.

(Please like the answer it will encourage me. Do comment if any correction required before disliking.)

A firm is considers introducing a new production line for its new product the Squeaky Clean. The production start-up costs are estimated to be £30,000 while the cash revenues are estimated at £20,000 per year. Cash costs (including taxes) will be £14,000 per year. Production will be wound down in eight years’ time and the salvage value at this time will be £2,000. The discount rate on similar projects is 15%. The objective of the firm is to maximize shareholder...

Digital Eye must design an assembly line to produce a new line of slim digital cameras. Assembling a single camera requires the completion of nine distinct tasks, and information about each of these tasks is provided below: Task Immediate Predecessors Task Duration (Seconds) A None 20 B A 15 C A 20 D B 12 E B 8 F B 15 G D,E 30 H C,F 25 I G,H 9 This assembly line will operate 8 hours a day to...

You are designing a process for the assembly of a consumer electronics product with a labor content of nine minutes. You are trying to decide whether to use (1) a single machine-paced line with eight workers or (2) eight separate single-worker “cells”. Each of the eight single-operator “cells” would perform exactly the same collection of assembly tasks as the single line, using the same tools, technologies and equipment. On the assembly line, each worker would be assigned to a single...

Sue Helms Appliances wants to establish an assembly line to manufacture its new product, the Micro Popcorn Popper. The goal is to produce five poppers per hour.

Woodbridge Manufacturing is also considering developing a new assembly line on which to build another new product (not covered in the text). In what category should the costs listed below be placed: Initial investment outlay (time0) Supplemental annual cash flows (time1 through timeN) Terminal value (timeN), or Disregarded? Also state your reasoning for choosing that classification. Consider each element individually. This product has been developed over the past three years, at a total cost of $125,000. The building that Woodbridge...

Jamaica Corp. is adding a new assembly line at a cost of $8.5 million. The firm expects the project to generate cash flows of $2 million, $3 million, $4 million, and $5 million over the next four years. Its cost of capital is 16 percent. What is the internal rate of return (IRR) that Jamaica can earn on this project and should the project be accepted? (Round to the nearest percent)? A. 18 percent, yes because IRR > r B....

The company is considering a new assembly line to replace the existing assembly line. The existing assembly line was installed 3 years ago at a cost of $90,000; it was being depreciated under the straight-line method. The existing assembly line is expected to have a usable life of 6 more years. The new assembly line costs $120,000; requires $9,000 in installation costs and $5,000 in training fees; it has a 6-year usable life and would be depreciated under the straight-line...
