- Question 1 A factory can produce four products denoted by X1, X2, X3 and X4. Each product must be processed in each of two workshops. The processing times (in hours per unit produced) are given in the following table: X1 X2 X3 X4 |Workshop 1 Workshop 2 3 4 8 2 5 8 There are 400 hours of labour available in each workshop. The profit margins are R48, R72, R120 and R108 per unit of X1, X2, X3 and X4 produced respec- tively. Everything that is produced can be sold. Thus, maximising profits, the following linear program can be used: Маx Z = 48X1 + 72X2 120X3 108X4, subject to 3X1 4X2 8X3 6X4 400 6X1 2X2 5X3 8X4 400 X1,X2,X3 2 0.

Two Architectural Companies have provided building plans and technical schematics for the project. Management are happy with the proposals of both Standard apartment and Deluxe apartment. After investigating the steps involved in construction, management determined that each apartment complex built will require some resources. Management analysed each of the bids and concluded that if the plans of Standard apartment are built, it requires 0.7 days in foundation works, 0.5 days in the masonry, 1 day in finishing, and 0.1 days in painting works. Deluxe apartment will require 1 day in foundation works, 0.83 days in the masonry, 0.67 days in finishing, and 0.25 days in the painting works. Management estimate that, 630 days for foundation works, 600 days for masonry, 708 days for finishing and 135 days for painting works…arrow_forwardQUESTION THREE A) Use the simplex method to solve the following LP problem.
