--- Question 3 - A paper-recycling plant processes box board, tissue paper, newsprint, and book paper into pulp that can be used to produce three grades of recycled paper (grades 1, 2 and 3). The prices per ton and the pulp contents of the four inputs are shown in Table 3. Input Cost (5) Pulp Content (%) 15 Box board 5 Tissue paper 6 20 8 30 10 40 Newsprint Book paper Table 3. Prices per ton and the pulp contents Two methods, de-inking and asphalt dispersion, can be used to process the four inputs into pulp. It costs $20 to de-ink a ton of any input. The process of de-inking removes 10% of the input's pulp. leaving 90% of the original pulp. It costs $15 to apply asphalt dispersion to a ton of material. The asphalt dispersion process removes 20% of the input's pulp. At most, 3,000 tons of input can be run through the asphalt dispersion process or the de-inking process. Grade 1 paper can only be produced with newsprint or book paper pulp: grade 2 paper, only with book paper, tissue paper, or box board pulp; and grade 3 paper, only with newsprint, tissue paper, or box board pulp. To meet its current demands, the company needs 500 tons of pulp for grade 1 paper, 500 tons of pulp for grade Z paper, and 600 tons of pulp for grade 3 paper. Minimize the cost of meeting the demands for pulp. 1. 2. Let x, be tons of raw material i purchased, for(i=1,2,3,4). Where Is box board, 2's x tissue paper, 3 s newsprint, and 4s book paper Let D, be tons of raw materal sent through de-ning for(i=1,2,3,4). Let 4, be tons of raw material i sent through asphat dispersen, for(i=1,2,3,4). Let P be type pulp produced, for(i=1,2,3,4). Let y, be tons of type ipupwed to produce grade paper, for (i=1,2,3,4 and j =1,2,3). The objective is to mmamize the cost of meeting demands for pup z =(cost of i input) (tons of input I purchased) +(cost of de-inking to any input) tons of input i sent through de-inking) +(cost of asphlat dispersion to any input) tons of input i sent through asphalt dispersion) = 5x +6x, +8x, +10x+20(D+D, +D+D.)+15(4+4+4+4) Thus, the objective fincton s.
