Processor Brake Down c emperical

Hello,


i would like to setup my processor (process time 6 seconds) with a c emperical down time function.

Means, i would like the processor to be down for 5% of the total runtime (so 95% is uptime there is no setup time).

For this 5 % of downtime i would like to set up a c emeprical ditribution.

i Setted up a table "ReturnBReakDown" which looks something like this: (so for 15% of the downtimes the downtime duration is 60 seconds a.s.o)

Percents Values
15 60
22 65
25 70
10 80
10 90
8 100


And this is what i inserted to run this:


But i have no idea how to tell te system that the downtime should be 5% and the rest 95% should be uptime?

PLease help =)

br

Paul

@paul.sf,

To receive a more accurate solution, please post your model or something similar that demonstrates your question. Proprietary models can be posted as a private question for FlexSim U.S. support only.

Also, one thing to mention when using a cempirical distribution. The numbers in the first column MUST add up to 100 (100%). In your post of what's in your model, it adds up to only 90%.

From the User Manual:

cempirical (str/node/num table[, num stream])

Returns a random sample from a continuous empirical distribution

Description

A continuous empirical distribution with percentages and values defined in the table specified.

Empirical distributions reference tables created by the user that contain a list of values and probability percentages associated with each value. Probability percentages must be entered in column 1 starting with row 1 of the table, and the associated values are entered in column 2. The table may have as many rows as needed to define as many values as desired. The percents are entered as numbers between 0 and 100, and should add up to a total of 100 percent; otherwise any values defined after a cumulative percentage of 100 is reached will never be returned.

Thanks.
