Using the diagram below, do the following:
a. Draw a tree diagram for the scissors.
b. Prepare an MRP plan for scissors. Lead times are one day for each component and final scissor assembly, but two days for the plastic grips. Six hundred pairs of scissors are needed on day 6.
Note: There are 200 straight blades and 350 bent blades on hand, and 40 top blade assemblies on hand. Use lot- for- lot ordering for all items.
