LP model for Product Mix Example: Decision variables: X_TV= the number of TV sets assembled, X_STEREO= the number of stereos, and X_SPEAKER= the number of speakers Objective Function: Our goal is to maximize the total gross profit. Maximize 75 x_TV + 50 x_STEREO + 35 x_SPEAKER (Profit) Constraints: Subject to: 1 x_TV + 1 x_STEREO + 0 x_SPEAKER <= 450 (Chassis) 1 x_TV + 0 x_STEREO + 0 x_SPEAKER <= 250 (Picture tubes) 2 x_TV + 2 x_STEREO + 1 x_SPEAKER <= 800 (Speaker cones) 1 x_TV + 1 x_STEREO + 0 x_SPEAKER <= 450 (Power supplies) 2 x_TV + 1 x_STEREO + 1 x_SPEAKER <= 600 (Electronics) x _TV >=0, x _STEREO >=0, x _SPEAKER >=0 (No negativity)
