Automation in manufacturing processes

The term automation refers to the technique through which the creation of an apparatus takes place using an automatic process or a system. Let us try to understand this with an example.

Question

In a manufacturing company, the routing of part A is started from machine X, and
continued by machine Y, and then machine Z, and 23,000 parts must be produced per
month. The routing of part B is machine Y, Z, and X, respectively, and 31,000 parts
must be produced per month. Set up time for machine X, Y, and Z are 35, 55, and 45
minutes, respectively. If the company works 6 days a week, four weeks a month, 10
hours a day, with 45 minutes lunch break and two breaks of 20 minutes, and given the

A very special manufacturing operation is being designed as an assembly line. Table 1 shows the tasks that need to be performed, their task time, and preceding tasks. The goal is to produce 5760 products per month. The company has an operation pattern of 24 days per month with 8 hours per day. Draw a precedence diagram. Determine the cycle time. Using the largest work element-time rule, assign tasks to the workstations in order to have appropriate line balancing. Identify the idle time for workstation 1, 2 and 6. Identify the number of workstations for the balanced line. Calculate the balanced line effieciency to 2 decimal places (Example 0.78).
