One of themachines on the line is a drill press that has a single assembly line feeding into it. A partially completed unit arrives at the press to be worked on every 8 minutes, onaverage, according to an exponential distribution. Themachine operator can process an average of 10 parts perhour (Poisson distributed). Determine the average numberof parts waiting to be worked on, the percentage of timethe operator is working, and the percentage of time themachine is idle.
- Explain in what kind of situations is queuing analysis is most important under waiting line models ? It's from operations management domain don't sent it to other subjects plz !In a waiting line situation, arrivals occur at a rate of 2 per minute, and the service times average 18 seconds. Assume the Poisson and exponential distributions. a. What is λ? b. What is μ? c. Find probability of no units in the system. d. Find average number of units in the system. e. Find average time in the waiting line. f. Find average time in the system. g. Find probability that there is one person waiting. h. Find probability an arrival will have to wait.

- The Draper Clinic has two general practitioners who seepatients daily. An average of 6.5 patients arrive at the clinicper hour (Poisson distributed). Each doctor spends an average of 15 minutes (exponentially distributed) with a patient.The patients wait in a waiting area until one of the two doctors is able to see them. However, since patients typically donot feel well when they come to the clinic, the doctors do notbelieve it is good practice to have a patient wait longer thanan average of 20 minutes. Should this clinic add a thirddoctor, and, if so, will this alleviate the waiting problem?One field representative services 5 customers for a computer manufacturer. Customers request assistance at an average (Poisson-distributed) rate of once every 3.1 working days. The field representative can handle an average (Poisson-distributed) of 1.0 call per day. Determine: Use Table 1. a. The expected number of customers waiting. (Round "X" value to 2 decimal places. Round your answer to 3 decimal places.) Expected number of customers waiting b. The average length of time customers must wait from the initial request for service until the service has been completed. (Round your answer to 2 decimal places.) Average length of time days c. The percentage of time the service rep will be idle. (Round your answer to 1 decimal place.) Percentage of Idle time d. By how much would your answer to part a be reduced if a second field rep were added? (Round your answer to 3 decimal places.) Reduced number of customer(s).1.An operator handles adjustments for a group of 8 machines. Adjustment time is exponentiallydistributed and has a mean of 12 minutes per machine.
