Mann Enterprises is a Houston manufacturer of tables and accessories for personal computers. The company is caught in a vicious cross fire between rapidly dropping market prices from competitors worldwide for its products and stable domestic costs for its materials. The 15 different products noted below must be scheduled to maximize profits or there will be no jobs and no firm in another 3 months. Your job as the new OM graduate is to address the issues raised this morning by Laura Mann, the president, in an emergency meeting in her office. Without being told so explicitly, you conclude that if you don’t get the schedule done accurately and in a timely manner, you will be history. To your relief, the industrial engineers and accountants have provided the data shown below. The issues, as recorded in your notes, are indented in (a) through (f). Steel Alloy Required (Lb.)
