Question: Students arrive at the Administrative Services Office at an average of one every 15 minutes, and their requests take on average 10 minutes to be processed. The service counter is staffed by only one clerk, Judy Gumshoes, who works eight hours per day. Assume Poisson arrivals and exponential service times.
b. How much time, on average, does a student spend waiting in line?
Understanding waiting in line or lines and learning how to oversee them is one of the most critical ranges in operations administration. It is essential to create the plan, work plan, inventory levels, etc. Each day, we hold up in line in our benefit economy, from driving to work to checking out at the general store. In brief, holding up lines is unavoidable.
Step 1: Waiting time
A student spends the following amount of waiting time on an average can be calculated using the following formula:
Step 2: Students spend an average time
is the average number of students waiting in line is 1.33
is the average waiting time in line?
Refer to Example 14.1 as the basis for this problem. Meritor hires a team of consultants. The consultants suggest partial robotic automation as well as an increase in safety stock to 12.5 percent. Meritor implements these suggestions. The result is an increase in efficiency in both the fabrication of muffler assembly and the making of catalytic converters. The muffler assembly fabrication cell now averages 16 assemblies per hour and the lead time has been decreased to two hours’ response time for a batch of 10 catalytic converters. How many kanban cards are now needed?
