Unformatted text preview: P 1 , P 2 , B excess > 0 (nonnegativity constraint) Homework 7 Solutions Fall 2010 7. Winston, page 116, Problem 20 Decision Variables: Let X 1 = Acres invested in tract 1 for Spruce X 2 = Acres invested in tract 1 for Hunting X 3 = Acres invested in tract 1 for Both X 4 = Acres invested in tract 2 for Spruce X 5 = Acres invested in tract 2 for Camping X 6 = Acres invested in tract 2 for Both Objective Function: max z = .2*X 1 + .4*X 2 + .5*X 3 + .06*X 4 + .09*X 5 + 1.1*X 6 (in thousands of dollars) Constraints: X 1 + X 2 + X 3 < 300 (allocation constraint for tract 1) X 4 + X 5 + X 6 < 100 (allocation constraint for tract 2) 3*X 1 + 3*X 2 + 4*X 3 + X 4 + 30*X 5 + 10*X 6 < 1,500 (capital constraint in hundreds of dollars) .1*X 1 + .2*X 2 + .2*X 3 + .05*X 4 + 5*X 5 + 1.01*X 6 < 200 (labor constraint in workerdays) X 1 , X 2 , X 3 , X 4 , X 5 , X 6 > 0 (nonnegativity constraint)...
