IBP Optimizer capacity

Hello,

I have a location and inside two ressources. each ressoruce can produce 280 pc.

Now I have a consensous demand of 350. If I run now the optimizer, the result is, that the kf CAPACITY UTILIZATION show me a utilization of 96 % for each ressoruce.

This is not that, what I expect.

How can I controll this? Perhaps I used the wrong KF. I want to see, that ressoruce 1 produce 280 pc and ressoruce 2 produce 70 pc. How can I see this and control the ressoruce sourcing ?

Thanks

Oliver

Hi Oliver,

I would suggest to turn off Time Independent Penalty Cost and use the cost what you have maintained in the Key Figure. Also, make sure you are not using any Discretization. Turning these off will reduce the complexity of the Optimizer solve and will get better results which you can understand easily.

Share the results what you get.

Hi Oliver - Presuming you are referring to time series Opt, you may very well achieve this by maintaining low production cost rate for the machine 1 and relatively higher cost rate for machine 2. That way, machine 1 is 100% utilised first and then machine 2 will be considered.

Thanks,

Hello,

I can't find a kf or customizing to managed the cost for each machine

Hi Oliver Richter,

I faced this issue earlier.

May I know which optimization mode is being used (profit maximization, delivery maximization).

Maintain global cost parameters default to 1.

Time-independent penalty cost to 1.

Discretization to 0.

Fair share distribution uncheck.

Other - optimizer runtime 60- 120.

PRODUCTIONCOSTRATE for machine 1 is 1 and the second machine is 10000. After these settings run the optimizer and check the results log.

Best Regards,

Hi Ankur,

thanks for the answer.

But what do you mean with Discretization ? And how can I turning this off ? 🙂

Thanks in advance

Hi Guru,

give it perhaps a time series indicator for prodcution cost rate that I have to acitvate in the MD ?

Hello,

I'm a little further with the optimizer. Now both machines will be used.

both machines has the same settings for costs and master data types. But the utilization of both is different . sometimes machine A has 100 % and machine B has 29 % and vice versa.

I expect 50 % and 50 % but this is not the result.

Can you explanin me why?

Thanks in advance

Hi Guru,

I attached a screen shot first with the result, that I don't understand optimizer-infint-result.png

than the cost settings optimizer-finit-cost.png

and the optimizer settings otimizer-finit-opt-setting.png

for my perspective, the machine 1 have to use for 100% but this is not the situation.

Can you say me why ?

Regards

Oliver

Hi Oliver -

I apologise, couldn't check your comments earlier. Hope you were able to find the reason? Frankly, it's not easy for me to comment on the behavior of Opt by just looking at it in one angle, master data needs to be checked, overall cost needs to be analysed. I don't think I could be of more help to you than giving the hint of going with PRODUCTIONCOSTRATE.

Thanks,

Hi Guru,

the situation is, that I first one ressoruce (Machine 1) with supply and a consensous demand from 280.

Now we want simulate and the consensous will be 500 pc.

Now I managed a new ressoruce with the same supply. (280 pc).

Now I managed the production cost. Maschine 1 is 1 € and Machine 2 is 100 €. All other cost are the same or for both not managed.

If I now let run the optimizer the first three periods, machine 1 will used by 100 % and the ret will be produced in the second machine. but then, it will be changed. Although the cost are higher for machine 2, the optimizer will use the machine 2 for 100 % and the rest will be produce in machine 2.

The forcast consumpton rate in the "Production Source Ressoruce" is for machine 1 = 1 and for machine 2 also 1

Hi Oliver - Somehow, I am not able to comment on your comments, hence posting it as an answer, my apologies.

So, you added production cost rate for both source ids, you added 1 for machine 1 and 500 for machine 2 but you say Opt is considering machine 2 ?? Opt is constrained planning and if you have a capacity of 280pc as you stated in your original post, it can't go beyond that. In addition, please note Opt considers the 'overall' cost, not just the production cost rate. So, if Opt is considering machine 2, it means the overall cost of getting it done from machine 2 and supplying it back to the DCs is somehow cheaper as per Opt. Please check what all other costs you had maintained - like Transportation cost (Rate), inventory holding cost etc.

Thanks,

Regards - Guru

Hi Oliver -

PRODUCTIONCOSTRATE is the key-figure which should be seen at PROD/LOC/SRCID level. Each SRCID corresponds to different machine, so you maintain the cost on this KF for a source id which relates to the corresponding machine.

Thanks,

Hi Guru,

thanks for this very good point. I have done this.

For the first machine, my production cost rate is 1 and for the second machine is 500. But If I start now the optimizer, he consider only the machine 2. I have changed the cost rate, but the result was the same.

Yes, I will use the TS Optimizer.

But I can't a key figure or a find a customizing point to managed the prodcution cost for machine 1 and machine 2.

If I use production cost kf, it is general production costs.

Hi Olaf,

Which Optimizer are you using? Is it the Time Series Optimizer?

kind regards

yes is a TS Optimizer.
