The materials used for this lab were filter papers‚ a choice chamber‚ eight pill bugs‚ water‚ and tin foil. The first step of the process is to trace and cut the filter paper so it fits neatly within each side of the choice chamber. Then‚ put water each filter paper and place the damp filter paper into the choice chamber. The damped filter paper causes the pill bugs to not be able to crawl under the paper and therefore disrupting the results. Four pill bugs should be placed on either side and one

Working with only a few variables at a time they allow operations managers to compare projected demand to existing capacity. The graphical method is a trial and error approach that can be easily done by a manager or even a clerical staff. Since it is trial and error though‚ it does not necessarily generate the optimal plan. One downside of this
