Entire Problem and figure 7.13 is attached.
Integer Linear Programming
Use problem 21 to answer part a and b.
Figure 7.13 from the text is included on page 2 of this document.
21. The Bayside Art Gallery is considering installing a video camera security system to reduce its insurance premiums. A diagram of the eight display rooms that Bayside uses for exhibitions is shown below in figure 7.13 (below); the openings between the rooms are numbered 1 through 13. A security firm proposed that two-way cameras be installed at some room openings. Each camera has the ability to monitor the two rooms between which the camera is located. For example, if a camera were located at opening number 4, rooms 1 and 4 would be covered; if a camera were located at opening 11, rooms 7 and 8 would be covered; and so on. Management decided not to locate a camera system at the entrance to the display rooms. The objective is to provide security coverage for all eight rooms using the minimum number of two-way cameras.
a. Formulate a 0-1 integer linear programming model that will enable Bayside’s management to determine the locations for the camera systems.
b. Solve the model formulated in part (a) to determine how many two-way cameras to purchase and where they should be located.
