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

Can someone explain how to get to the result for Q3E? I'm not sure how to get to the number after the cost increase (from $35 to $45)
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..

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?
View 1 more comment
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
Can someone explain how to get to those values?

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

I am actually saying that one answer possibility is missing, since the real assignment gives ABCDE
I think that D should then be B&C
shouldnt we round down here?
