Q1.
Variable definition :
Number of non-smoking Deluxe villas = NSD
Number of smoking Deluxe villas = SD
Number of non-smoking premier villas = NSP
Number of smoking premier villas = SP
Objective function:
Revenue per night for Smoking Deluxe = 130 + 15 = 145
Revenue per night for Smoking Premier = 175 + 15 = 190
As consultant for Adventures & Vacations LLC, we'd like to maximize revenue for the client.
Total revenue per day = 130*NSD + 145*SD + 175*NSP + 190*SP
Constraints:
SD + SP > 50%*(NSD + NSP)
SD + SP > 0.5*(NSD + NSP) .......Constraint as villas that allow smoking should be more more than 50% of the number of non-smoking rooms
SD + NSD >=100 .......Constraint as there should be at least 100 deluxe rooms
SD + NSD <=180 .......Constraint as there should be no more than 180 deluxe rooms
Cost for Smoking Deluxe villa= 12000 + 3000 = 15000
Cost for Smoking Premier villa= 15000 + 3000 = 18000
NSD*12000 + SD*15000 + NSP*15000 + SP*18000 <= 6300000 ........Contraint as budget constraint of $6.3 Million
SD + NSD >= 1.5*(SP + NSP) .......Constraint as number of deluxe rooms be at least 1.5 times the number of the premier rooms
SD + NSD <= 2.5*(SP + NSP) .......Constraint as number of deluxe rooms be no more than 2.5 times the number of the premier rooms
SD, NSD, SP, NSP >=0 .........Non-negativity constraint as number of villas cannot be negative
