The Texas Consolidated Electronics Company is contemplating a research and development program
encompassing eight research projects. The company is constrained from embarking on all projects by
the number of available management scientists (40) and the budget available for R&D projects
($300,000). Further, if project 2 is selected, project 5 must also be selected (but not vice versa). Table
below lists the resource requirements and the estimated profit for each project. The company wants
to decide which of those projects need to be taken on to maximize the total profit for the company.
Formulate an integer programming model for this problem. Define x₁, where i=1, 2, 3, 8 such that
if x=1, project i would be taken on; and if x=0, project i would not. Define Z as the total profit
($1,000,000). Which of the following objective function is correct?
