Question 1 1 A project has 62 activities but only nine of them are discussed in this problem. Activity E, duration = 10 days, IP = unknown Activity F, duration = 24 days, IP = unknown Activity G, duration = 14 days, IP = unknown Activity N, duration = 18 days, IP = E, F Activity P, duration = 11 days, IP = F Activity Q, duration = 18 days, IP = G Activity Y, duration = 11 days, IP = N Activity Z, duration = 23 days, IP = P, Q Activity A, duration = 10 days, IP = P, Q If ES of E = 23, ES of F = 18, and ES of G = 21, the earliest finish of A is at the end of day Question 2 A project has 62 activities but only nine of them are discussed in this problem. Activity E, duration = 18 days, IP = unknown Activity F, duration = 12 days, IP = unknown Activity G, duration = 24 days, IP = unknown Activity N, duration = 24 days, IP = E, F Activity P, duration = 19 days, IP = F Activity Q, duration = 25 days, IP = G Activity Y, duration = 19 days, IP = N Activity Z, duration = 15 days, IP = P, Q Activity A, duration = 25 days, IP = P, Q If LF of Y = 102, LF of Z = 144, and LF of A = 102, the latest start of F is at the end of day A Question 3 A company wants to launch a promotional campaign. It has an advertising budget of $135,000. There are two types of advertising media: (1) ads on newspaper and (2) television spots during afternoon hours. Each television spots costs $11,500 and each newspaper ads costs $2,200. The expected exposure is 53,000 viewers for each television spot and 18,000 readers for each newspaper ad. There are opportunity to purchase a maximum of 18 television spots and 40 newspaper ads. Based on past experiences, the company prefers to put at least five television spots and at least 10 newspaper ads. You must help the company to find the best mix of advertising media using a LP model. Assume the company wants to reach the highest possible viewers and readers. Decision variables are: N = number of newspaper ad T = number of TV spots Show clearly the mathematical expression of the constraint associated with the lower limit for the number of newspaper ads
