Assembly Line Balancing 4.16 The letters in the table below represent work elements in an assembly precedence diagram. (a) Construct the precedence diagram and (b) determine the total work content time. (c) Use the largest candidate rule to assign work elements to stations using a service time (T_s) of 1.5 min, and (d) compute the balance delay for your solution. Work element or tasks A B C D E F G H I J Time (min) 0.5 0.3 0.8 1.1 0.6 0.2 0.7 1.0 0.9 0.4 Preceding — A A A B, C D E F F G, H, I 4.17 Solve the previous problem but use the Kilbridge and Wester method in part (c).

Step 1
The work elements are represented by letters and each has a specific time associated with it. The preceding tasks are the tasks that need to be completed before a certain task can begin. (a) The precedence diagram would look something like this: ``` B - C | Show more…

PROBLEM 2B: AN ASSEMBLY LINE BALANCING PROBLEM The shop works a 400-minute day. The manager of the shop wants an output of 200 units per day for the assembly line that has the elemental tasks shown in the table: Do the following: 1. Construct the precedence diagram: Assign tasks using the most-following-tasks rule as the primary rule and the greatest-positional-weight rule as the secondary rule. 2. Compute the balance delay and the efficiency of your balance.

The desired daily output for an assembly line is 420 units. This assembly line will operate 546 minutes per day. The following table contains information on this product's task times and precedence relationships: TASK TASK TIME (SECONDS) IMMEDIATE PREDECESSOR A 35 — B 25 A C 18 B D 67 B E 36 A F 32 E G 42 C, D H 27 F, G b. What is the workstation cycle time? Cycle time seconds c. Balance this line using the largest number of following tasks. Use the longest task time as a secondary criterion. (Leave no cells blank - be certain to enter "0" wherever required.) Workstation Task Idle Time I II III IV d. What is the efficiency of your line balance? (Round your answer to 2 decimal places.)

Suppose the times for the individual operations for the in-line skate assembly are as follows: Task Description Time (sec) 1 Assemble wheels, bearings, and axle hardware 11 2 Assemble brake housing and pad 7 3 Complete wheel assembly 10 4 Inspect wheel assembly 10 5 Assemble boot 16 6 Join boot and wheel subassemblies 8 7 Add line and final assembly 7 8 Perform final inspection 11 Consider the production line achieving an output rate of 200 per hour below. Using the proposed design, calculate the total time and idle time for each workstation. If your answer is zero, enter "0". Round your answers to the nearest whole number. Station Tasks Total Time, seconds Idle Time, seconds A 1 and 2 B 3 C 5 D 4 and 6 E 7 and 8 Total What is the assembly line efficiency? Round your answer to one decimal place.
