What is an appropriate objective function and constraints for this vacation?

What will be an ideal response?

Answer: Using the scheme of location (J, C, or G) and excursion (S, P, H, L, Te or Tu), the model should be expressed as:
Max Z = 3JS + 1JP + 2JH + 3JL + 2CS + 3CP + 1CH + 2CL + 3CTe + 1GS + 2GP + 3GH + 1GL + 3GTu
subject to:
100JS + 95JP + 120JH + 60JL + 110CS + 55CP + 70CH + 90CL + 130CTe + 90GS + 60GP + 110GH + 130GL + 95GTu <= 250
JS + JP + JH + JL ≤ 1
CS + CP + CH + CL + CTe ≤ 1
GS + GP + GH + GL + GTu ≤ 1
JS + CS + GS ≤ 1
JP + CP + GP <= 1
JH + CH + GH <= 1
JL + CL + GL <= 1
JS, JP, JH, JL, CS, CP, CH, CL, CTe, GS, GP, GH, GL, GTu are 0,1
