I am working on a project where I need to calculate the Erlang C.
In excel it is easy but in qlikview it is more difficult.
I managed to do it using variables but I cant get it to work in a table.
Here are the variables I created to calculate the Erlang C:
let vDen = 0;
let vNC = 360;//Number of calls
Let vP = 900;//Period length
Let vT = 120;//Average call duration
let m = 55;//Number of agent
let tt = 30;//Target answer time
Let u = num((($(vNC)/$(vP))*$(vT)),'#0 ');//traffic intensity
Let vOCC = $(u)/$(m);
Let vNUM = num(pow($(u),$(m))/fact($(m)),'#0 ');
for i=0 to $(m)-1
let vDen = $(vDen)+ (pow($(u),$(i))/fact($(i)));
let vErlang = Num(vNUM/(vNUM+((1-vOCC)*vDen)),'# ##0.00%');
In the table I am not able to calculate the vDen as I cannot create the loop in the expression tab.
