Epsilon Airlines services predeminately the eastern and southeastern United States, A vast majerity of Epsilon's customers make reservations through Epsilon's website, but a small percentage of customers make reservations via phone. Epsilon empioys callcenter personnel to handie these reservations along with any problems with the website reservation system and for the rebocking of filghts for customers if their plans change or their travel is disnupted. Staffing the call center appropelately is a chalienge for Epsibn's management team, Hoving too many employees on hand is a waste of money, but having too few results in very poor customer service and the potential loss of customers.

These estimates are given in the following table. The call-center emplovees work five consecutive days and then have two consecutive days off. An employee may start work any day of the week. Each call-center employee receives the same salary, Assume that the schedule cycles and ignore start-up and stopping of the schedule. Develop a model that wil minimize the total number of cal-center employees needed to meet the minimum requirements, \{Let xj= the number of call-center employees who start work on day i where i=1 = Monday. i=2= Tuesday, etc).
