Why don't we round up from 163.30 to 164? Since we are talking about real items?

The Efficiency Formula doesn't work.
why is it 1.1 and not 1.4 *6
do not forget to send comments tomorrow for the exam, thanks

There are several mistakes in this file. Including in the formula for 'efficient capacity'; no of orders placed yearly; forecast only for 7 days; and more that I won't disclose. I'd suggest not to use it.
why do you use 4 instead of 2 or 6?

Because we are looking for the forecast average error over a number of periods, n symbols your periods and you have 4 periods (7, 8, 9 and 10).
thank you and thank you for uploading this it really is amazing. <3
Could you explain what the theory behind this is?
Maximum Capacity means for how many persons per hour the operations are designed for under ideal conditions. And its d) because the sink can take up to 120 persons per hour
I don't think so they're asking for the design capacity of the operation with the max capacity (which is 75), the handdryer, which has a design capacity of 100 so the answer should be A right?

Hey, for the Resit Exam 2018 Question 14.) this solver doesn't give the correct answer. However I don't think it is the solvers problem. Does someone know what is going on here? Please help, otherwise I am dying
What is the correct way to get to 60%? And in which chapter do i find takt time + efficiency calculations?
It is in chapter 5 and the correct way is 18/2*15= 0.6 The reason for this is you have to add the time of all workstations=18 Thn allocate the activities to the workstations which result in 2 workstations and then takt time was given in this case
but how do you get 2 wokstations when they stated to use the theoretical one? if we use the formula for # of workstations, we get a 1.2

Does someone know how to calculate the Total Transportation Cost for question 50?
how to do this
No area was marked for this question
Why did you circle both E & F together and not E by itself only?
View 1 more comment
Because as said before it is about the theoretical number of workstations so Total number of minutes required/takt time. Which mean sin this case 18/15=1.2 and for workststations you always have to round up so 2
Hey Guys, so how do we now that the planned order receipts/releases here are 200? The Quantity is 200 because of the FOQ, but why exactly in these Weeks(Periods)?
Because the lead time is one week so you need to release the orders in week 1 so you can receive them in week 2. It is just because you cannot order in week 0 but have to take the first week possible
the actual answer is 1414.21 , So why we do not round up?
You have to round down and not up because for EOQ you only have to roud to next intger number but with the normal rounding rules
Are all mathematical questions of 2018 past papers and beyond relevant?
in the question it's written for every 1 Decoration it needs 2 Sugar. So you take the planned order releases from Table D and multiply them by 2 and directly put them in Table B gross requirements in the same week they occurred in Table D

What if there are more weeks/days tho ?
The planned order releases do not influence the rest of your table, so you can just adjust them yourself. I.e. if you have a lead time of 1 week the POreleases of week 1 are the POReceipts of week 2. If you have a 2 week lead time, the POreleases is week 1 are the POReceipts of week 3
Could someone maybe explain how you get this 490 and not -10 (500 - 270 -240)?
There is a mistake in the table becaaue in week 2 you also have 500 plannes order receipts so then you have 230+500-240 which results in 490 available invenotry :)

can you make it longer cause its usually 8 weeks/days thanks

If you go on the student portal and then on examination material you can see it under the resit and firstsit called e.g "MRS+MRP banana split"

Why sometimes you found a number like 120 for safety stock and you wrote 119 in the cell ?

That’s not correct cause it would be 425.2 and you need to round up. I think you made a mistake with the z-score from the table.
yea the z score is 0.28 sry didn't correct on the previous line but it's 400+0.28x90 = 425.2

I realised 4 cells turned to 0. The formulas that should be in them are the following: D43: =(C43 + D45 - D41 + D42) D44: =(D41 + B35 - C43 - D42) E43: =(D43 + E45 - E41 + E42) E44: = (E41 + B35 - D43 - E42)

I think there is a mistake in the Solution of Problem nr 16. In the MRP Record of Wafer the net requirements of week 3 should be -64.
NR can never be zero it is always either 0 or more and this is the correct solution from the student portal
No this is actually correct, as you have to caluclate 0(GR)+300(SS)-164(IT) and then you end up with 136
Because you have to caluclate the new EOQ for the dicsount which is 13,693 and as this is bigger than the minimum order quantitiy therefore you have to calculate the TAC with 13,683 instead of 2000 :)
Where does this belong to? Help is much appreciated!
How do you calculate this?
From the text they say "forty claims need to be processed" so 40 is the output needed to meet the customer demand

For Question 23, you need to calculate the MAD, which concludes about the accuracy of the forecasting bias, so its (347.38+122.12+(880+590)+(1100-603.67)+(1340-712)+(1660-974.67)≈428.193 -> so A)
True but there is a typo in your calculation should be 880-590 and it should be all divided by 6
