Goodmorning Hans,
Is it possible to mail me a copy of the Kanban game.We are on our way to implement Kanban.Maybe this simulatian can take away scepsis by some people.
Thanx in advance,
Bernard
PS Hans seems a Dutch name to me. Where are you from?
 

Andy, This is very much appreciated. I’ll get in touch with them. Bernard

Hi SB
I use a rule of thumb to have at least 25 data point to make an estimation about the kind of distribution. Think this work wel for correlation and regression.

Hi Hero,
OK so far.Need some more detailed info to solve the problem.- kind of operation per station- personel per station- ect.If you want, you can mail me a flowchart, floorplan ect. to [email protected]
 

Hi Hero,
Alway’s nice to solve this kind of puzzles!
Please answer the following question before I start:
Did I understand that:- for stations 1-3 and 5-9 the average operation time is 90 sec. per station?- for station 4 it’s 204 sec?- when you have an “one piece flow”, and when station 4 was also 90 sec., your takt time will be 90 sec, in…[Read more]

Hi Vidya,
Take a look at http://hal.lamar.edu/~ie_dept/underdown/Work_Design/INEN_3380.htm
Let me know if it is helpfull

Peter,
Are you familiar with the Kaizen 5S concept?
Your team can create an Audit Form and use the periodical outcome as your metric.Mail me if you need some support.

Hi Pepe,
Thank you for responding.When it’s indeed 98% we can live with that.Has it to do with paralel or serial flows, just as with currency?
Is it possible to explain to me why the chance to make an end assembly is 98% and not less?I will be grateful when you could explain it to me.
Best regards,
Bernard
 

Hi Andy and Peppe,
Thanx for your replies.
Maybe I have to formulate things in an other way:
300 types end assemblies .Each type end assembly consist of a different combination of 40 parts out of a pool of 500 part numbers.Per part number is the chance that it is available 98%.So, what is the chance that I can assemble a random chosen end…[Read more]

Hi Andy,
stddev is related to the part usage in the end assemblies over the last year.For examp.:
week 1         45 partsweek 2        200 partsweek 3         20 partsect.stddev = 98assume MCT = 2 weeksSafety stock = 98 x 2 x  2^0.7 = 318With this 318 parts safety stock you make sure that for 98% (+/- 2 sdtdev under the normal curve) parts are…[Read more]

Hi Andy,

Hi Andy,
stddev is related to the part usage in the end assemblies over the last year .
For examp:
week 1  

Hi Andy,
Safety stock is calculated as follow:
Sdtdev (historcal orders) * service level * (manuf. cycle time)^0.7
So, a service level of  2 wil give an availability of 98%But what happens when I have 40 parts in my assembly?
45% chance that I can assemble my finished good??
Best regards,Bernard
 

Hi Stevo,
Who said Jessica is female?All those guys are just offering help.

Hi Jessica,
I think the the big Y is your cycle time an de X’s are the knobs you can turn to decrease you Y:
– work in progress (queue)- process (machine) failures- non value added oprerations in your process- first pass yield (do the tings right the first times)- amount of process steps- ect.
Very curious about your process and the project…[Read more]

Thanks Adam,
Waste in design is a good hint!!
We have already made the statistics (that’s why we start the project).Here some rough data:- tubes (end parts, scrap..) – 10% = 273T- chips (steel/cast iron) – 50% = 1240T- sheet metal (stamping waste) – 44% = 237T
Total amount of waste = 1750T = 1.300.000 euro/yr
With best regards,
Bernard
