Could someone explain how to reach EUR3700 on the project managamenet question c please? Its obvious that A is crashed first but then I am unsure as there are 3 other possible paths
So youre right, you start ith A since it has the lowest costs. You can never take C (since it is shorter than B (it is not on the citical path) and B cannot be crashed, so crashing C wouldnt impact your finishing time; same for F). Go along your critical path, you can crash G twice (2x1000) which is the best option. Now youre still missing one week. Therefore, crash week H (1200).
500+1000+1000+1200=3700
Hey guys,
there was a question with forecasting regarding pessimistic scenario and confidence interval for forecast.
Could someone please explain how to do those based on regression output?
Why do we put:
IuM + IaM + PuM + PaM - IuTu - IaTu = 3?
I do not get why the PuM + PaM part also needs to be equal to 3, since we have to order for Monday - Tuesday and Wednesday?
Thank you!
Q1 was about minimax and maximin, forgot the subject
Q2 was with linear programming and the different wines
Q3 was setting up the chase plan and and level plan with different values
Q4 was the LP with delivering papers
I got a decrease of -5780 (rounded), I didn't do anything with the $10 increase since it's lower then the reduced cost.
I don't know if that's correct..
the page numbers don't refer to any book but to the summary "Management of operations and product development EXAM FOLDER" which also had an index but it was a bit small
For problem 21 assignment 20, are you sure it's right? Shouldn't it first be calculated the new ROP point with the fixed-interval method (as I understand they're asking us for) and after calculate the new z value?
for a fixed interval model there is no ROP, as you are always ordering in fixed intervals

Thanks Julie. And Anonymous Knife, I realized I miswrote it, I meant that as in that part we are supposed to not do the ROP but to calculate a new order size with the fixed interval method
z-score for 94% (100-6 because of 1% increase) is equal to=1,56
so the new safety stock is equal to = 156
old one was 165
165-156=9
9/165=0.0545=5.45%

Does somebody know how much in detail we need to go for Chapter 13 (Tutorial 10 about Inventory management?) Do we need to be familiar with all of the examples, of just those seen in the tutorial? It's because personally i don't understand some of the examples given in the book. Thanks!
For open-ended question on Inventory management on Safety stock, where do i find Appendix B as mentioned in the book to find the correct z score? thanks
in the file it's 14.400, and here it's just changed to 15.000, why arent the labor costs just the hours required * $25? because it doesn't say anywhere that they cannot work parttime I guess?
Can someone explain how to find overtime here ? I know we are suppose to start with the biggest forecast and calculate it from there but I forgot how ! Thankkssss
