Solving Real World Complex Answer Questions

  1. Solving real world complex problems using either traditional optimization techniques or modern heuristic techniques would make interesting work. What do the terms heuristic and optimization (or optimal) mean? What is a quantitative application for each? Some independent research is needed. What was your source(s) for addressing this question? Provide a URL address(s) if applicable. Don’t hesitate to use outside sources in addressing questions in this course, and apply your understanding as it relates to your prior knowledge and experience where appropriate.
  2. What is implementation, and why is it important?

  6. Jan Gentry is the owner of a small company that produces electric scissors used to cut fabric. The annual demand is for 8,000 scissors, and Jan produces the scissors in batches. On the average, Jan can produce 150 scissors per day, and during the production process, demand for scissors has been about 40 scissors per day. The cost to set up the production process is $100, and it costs Jan 30 cents to carry one pair of scissors for one year. How many scissors should Jan produce in each batch?
  7. The EOQ model has a number of assumptions. List them and explain whether they are readily attainable. For example, will the adjustment for quantity discounts easily work?
