Ray: I will use a CPM technique to develop the plan.

Patricia: That sounds great. We will be using the new gates starting from 6 AM to 10 PM every day of the week. As you know, all our employees work two shifts, morning shift from 6 AM to 2 PM and the afternoon shift from 2 PM to 10 PM. I need to tell David about the number of new customer service people we need to hire for the additional gates. I promised to get back to him in a week.

Ray: From the passenger forecast, I can use our regular rule of one agent for every hundred passengers. I will also make sure that every employee gets two consecutive days off. I will also add the usual 10% additional staff to cover vacations, sick-days, and absenteeism.

Patricia: You seem to be a quick learner and your knowledge of our operations is a definite plus. One last thing which you may be able to help me with this week is responding to Paul, our V.P. of communications, about delays in our flights. Typically, in our industry, three to fifteen percent of the flights are late. Paul wanted to know how we are doing compared to the industry. I had asked flight operations to send the sample data about flight delays.
