Please help A manual assembly line is to be designed to make a small consumer product. The work ele-ments, their times, and precedence constraints are given in the table below. The workers willoperate the line for 400 min per day and must produce 300 products per day. A mechanizedbelt, moving at a speed of 1.25 m/min, will transport the products between stations. Becauseof the variability in the time required to perform the assembly operations, it has been deter-mined that the tolerance time should be 1.5 times the cycle time of the line. (a) Determinethe ideal minimum number of workers on the line. (b) Use the Kilbridge and Wester methodto balance the line. (c) Compute the balance delay for your solution in part (b).Element12345Time Te0.4 min0.7 min0.5 min0.8 min1.0 minPreceded by22,3Element678910Time Te0.2 min0.3 min0.9 min0.3 min0.5 minPreceded by34) aver4,95,67,8

An assembly line with 17 tasks is to be balanced. The longest task is 2.4 minutes, and the totaltime for all tasks is 18 minutes. The line will operate for 450 minutes per day.a. What are the minimum and maximum cycle times?
Mr. Aris Benn manages an assembly line that produces a piece of equipment that is used to clean floors. The process to produce this piece of equipment consists of 10 steps. Determine what other information is needed in order to balance this assembly line. Also, set up a numerical example of the line balancing problem at hand. Using this example, demonstrate how to balance the line and how to calculate its efficiency.

You have just determined the actual number of workstations that will be used on an assembly line to be 6 using the assembly-line balancing procedure. The cycle time of the line is 5 minutes and the sum of all that tasks required on the line is 25 minutes. What is the resulting line's efficiency?
given information: which step is in bottleneck=30 min for tan leather 60/30=2 briefcases per hr are processed at the bottleneck workstation per hour throughput time of the overall process Throughput = 75 minutes PLEASE answer the following 3 questions: If the manufacturing facility operates 8 hours per day, 250 days a year, what is the annual capacity of this manufacturing process. Assume the company decides to hire additional workers in order to duplicate the bottleneck step identified in part a so that there are 3 of these workstations instead of 1. Redraw the diagram showing the flow of the revised process. Answer parts a through d again based on the new process created in part e?
Dr. Lori Baker, operations manager at Nesa Electronics, prides herself on excellent assembly line balancing. She has been told that the firm needs to complete 96 instruments per 24-hour day. The assembly-line tasks for the production of the instrument are: Task Time (minutes) Predecessors A 3 ---- B 6 ---- C 7 A D 5 A, B E 2 B F 4 C G 5 F H 7 D, E I 1 H J 6 E K 4 G, I, J Draw the precedence diagram If the daily production (24-hour) production rate is 96 units, what is the highest allowable cycle time? If the cycle time after allowances is given as 12 minutes, what is the daily (24-hour) production rate? With a 12-minute cycle time, what is the theoretical minimum number of stations with which the line can be balanced? Assign task to workstations. Use the following decision rules (heuristics): longest task first, break ties by assigning the task with the most followers. What are the efficiency and the balance delay of the assembly line?
