Basic Situation 6 S(3,p)/M/1
Image of page 6
We assume that each customer has a probability of p of showing up, and if he shows up he does so exactly at his scheduled arrival time. The objective is to determine a schedule for a fixed number of customers, minimizing the sum of expected customers’ waiting costs and expected server’s availability cost. There is a single server to provide a Markovian service who remains available until the last customer leaves the system. The server has no prior knowledge of which customers will show up; hence, he has to remain available at least until the time the last customer is scheduled to arrive. Customers are served in the order of their scheduled appointments. Denote the scheduled arrival of the kth customer by tk, then if ti =tj, i<j, and both customers i and j show up, customer i is served before customer j.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
