Deutchlander Machine Company (DMC) makes two types of printing presses: a four-color litho and a two-color litho. Demand for both products is booming and exceeds DMC’s ability to satisfy it. Most raw materials are plentiful, but production is limited by three factors: a shortage of steel rollers, gear cutting capacity, and roller polishing capacity. Each four-color press requires 16 rollers, and each two-color press requires 8 rollers. The four-color presses require 30 hours of gear cutting and 8 hours of polishing time, and the two-color presses require 12 hours of gear cutting and 3 hours of polishing time. DMC is able to buy 100 rollers per week, and it has 160 hours of gear cutting time and 40 hours of polishing time available per week. To avoid harming long-term sales, DMC does not want to raise prices. At current prices DMC will earn a profit of 24,000 on each four-color press made and 10,000 on each two-color press made. So as not to abandon either product market, DMC also wants to produce at least two units of each press each week.   b.  Solve the LP Problem above using the Simplex method.

Question

Deutchlander Machine Company (DMC) makes two types of printing presses: a four-color litho and a two-color litho. Demand for both products is booming and exceeds DMC’s ability to satisfy it. Most raw materials are plentiful, but production is limited by three factors: a shortage of steel rollers, gear cutting capacity, and roller polishing capacity.
Each four-color press requires 16 rollers, and each two-color press requires 8 rollers. The four-color presses require 30 hours of gear cutting and 8 hours of polishing time, and the two-color presses require 12 hours of gear cutting and 3 hours of polishing time. DMC is able to buy 100 rollers per week, and it has 160 hours of gear cutting time and 40 hours of polishing time available per week.
To avoid harming long-term sales, DMC does not want to raise prices. At current prices DMC will earn a profit of 24,000 on each four-color press made and 10,000 on each two-color press made. So as not to abandon either product market, DMC also wants to produce at least two units of each press each week.
