Unformatted text preview: i be the available supply of resource R i . Let a ij be the amount of resource R i used in operating activity A j . Let c j be the net value to the company of operating activity A j . The problem is to choose the activities that maximize the value of the output to the company subject to the given resources. Keep in mind you are choosing activities. a) There is a dependency requirement in choosing the activities: activity A 3 can only be chosen if activity A 5 is already employed. How do you mathematically incorporate it in your model? b) What if there is a conflict between two activities such that activity A 1 and activity A 6 have conflict and should not be selected together. (i.e. only one of them can be selected at the same time) 3. a) Write a mathematical program for problem 15 of your textbook and solve it with AMPL. b) Linearize your model and solve it in AMPL....
