You use linear programming to develop a management strategy that includes a number of different constraints to address a variety of objectives. Your objective function is to minimize use of herbicides. In five different LP trials you use different sets of constraints (Table 2). The resulting level of herbicide application through time is illustrated for each in Figure 2. Using only the information provided here, enter in Table 2 the letter of the herbicide profile from Figure 1 most likely resulting from each flow constraint setting. Table 2. Flow Constraints non-declining flow for total volume (all species & products combined) even flow for total volume (all species & products combined) even flow hardwood volume (all products combined) AND even flow softwood volume (all products combined) none even flow hardwood volume (all products combined) AND even flow softwood volume (all products combined) non-declining area of old forest after year 2050 Herbicide Application Profile (ABCDE) E D A B Data For Figure 1 Yrs in A B C D E Future 0 20 27 1 40 7 569NN 211 60 7 6 2 80 7 6 2 100 1 8 38 68 6 4 21 30 15 25 123 45 4 4 6 33 3 32 Application ABCDE) 5 0 8765 A --B ----CDE E Area 4 O C (k ha) 3 A 2 D 1 A 0 0 20 40 60 80 100 Years From Now B Fig 1.
