(Solved) : Generalized Model 5 4 Text Book Two Additional Types Items Doodads Kontraptions Well Widge Q32520017 . . .
Generalized Model 5-4 (in the text book) to have two additionaltypes of items (doodads and kontraptions), as well as widgets;initially, there are 60 widgets, 50 doodads and 70 kontraptions.The customers arrive in the same pattern as before, but now eachcustomer will have a demand for doodads and kontraptions, as wellas for widgets. Widget demands are as before, doodad demands arePOIS(1,9) and kontraptions demand are POIS(2,3); assume that the acustomer’s demand for an item is independent of his or her demandsfor the other two items. There is still one inventory evaluator,who still arrives at the beginning of each day, but now has to lookat all three inventories and order according to separate (s, S)policies for each of the three inventories, you may “clone” thisinventory evaluator for this triple duty, using two tandeminstances of the separate flowchart module. For widgets (s, S) =(20, 40) as before for doodads, (s, S) = (15, 35); and forkontraptions (s, S) = (25, 45). Delivery lags for widgets are UNIF(0.5, 1.0) as before; for doodads, it is UNIF(0.4,0.8) and forkontraptions, it is UNIF(0.8,1.7); note that for kontraptions, itis possible for a delivery lag to extend beyond the time of thenext inventory evaluation, but make the order decision based ononly the inventory on hand , rather than based on the inventory onhand plus on order (even though the latter might make more sense;see Exercise 5-25). Ordering costs (both setup and incremental),holding and shortage costs for doodads and kontraptions are thesame for widgets. Run the simulation for the same length as model5-4 (that is, it is ok to fudge the ending point to avoid uselessinventory evaluation at time 120), and get the total daily cost, aswell as separate holding and shortage costs for each type of itemsin inventory. Describe how you model this if you had hundreds orthousands of different kinds of items inventory instead of justthree.
