Source Produce items at the start of each weekday..

Hi everyone

I m building a model in which I want the source to produce some quantity of items at the start of each day ( I have used the shift calender & in my model simulation starts at 8.00 am on all weekdays)

Now I want the source to create some quantity ( which I give it in a table ) of items at 8.00 am every day... Saturday & sunday are downtime in the model..

I dont know how to control the source by shift calender timings ..the quantity of items varies every day.

Any suggestion will be of great help..

Thanks in advance

Hi,

perhaps you don't use a source, you use a User Event, build a new box in your model and move this box to a queue. In the On Entry trigger you write a code to duplicate this box as often as you need it.

/**Create Box in User Event*/
createcopy(node("/1/2/1/1",model()),model()); // copy a box to your model
moveobject(last(model()),node("/Objectname",model()));
// last(model()) is your new box

Thanks a lot Jorg...

I have tried your suggestion.. I have two more question now..

1. If I use a User event and set the repeat time as 1440 mins ( 24hr * 60 ) it is creating items at 8.00 am every day.. but I dont want items to be created on saturday & Sunday.. any help on how to do that..

2. Is it easy to set itemtypes by this approach as I have 4 itemtypes and each come on a particular day.

Thanks once again Jorg..

Hi,

you can divert your items on saturday and sunday direct to a sink.

You can change the itemtypes on every trigger. To find the right itemtype build a counter, which counts the days, and set the itemtypes from a table.
I use the modulo operator in a switch-structure to repeat settings.

switch((counted_days % 7))
{
case 1:
{ ...
break;}
case 2:
{ ...
break;}
..
default: // the seventh day
{ ...
;}
}

Maybe a different approach:
Use a source with an arrival schedule to generate an item every morning but not on saturday and sunday. This product goes throug a seperator that generates the right amount of items based on table or distribution (use the "split or unpack quantity trigger")

Hi Jorg & Steve

I tried both the approaches and both works fine..

It was good learning from you guys..

Thanks a lot Jorg & Steve
