Uhura Enterprises provides consulting services for customers. Consultants are brought
in for two-hour shifts. A consultant will spend one full hour with a customer. The
customers remain for that hour and then leaves. Each consultant is paid $25 per hour.
Let Xirepresent the number of consultants starting their shift at hour i, (i = 1,2,3,4). The
firm wishes to minimize salary costs while satisfying demand. Customer demand is as
follows.
Suppose that if consultants start shifts at both 1:00 and 2:00, then the firm will incur an
additional fixed cost of $100 (for secretarial support). Let Y be a binary (0-1) variable
that equals 1 if this event occurs, and 0 otherwise. Which of the following would
‘activate’ Y (i.e., which would force Y to equal 1 when it is supposed to)? (In the options
below, Y and qiare binary (0-1) variables.)
