Task Sequence Example 1

I have two item(type1,2), and type2 is high priority.
Type2 is very important. But a Transporter only load one item.
So I do the code in "Request Transport From"


treenode ts = createemptytasksequence(centerobject(current,1),ge titemtype(item),1);
inserttask(newts,TASKTYPE_TRAVEL,current,NULL);
inserttask(newts,TASKTYPE_BREAK,NULL,NULL);
/* I want to transfer type2 priority by "break to" */
inserttask(newts,TASKTYPE_FRLOAD,item,current,port );
inserttask(newts,TASKTYPE_TRAVEL,outobject(current ,port),NULL);
inserttask(newts,TASKTYPE_FRUNLOAD,item,outobject( current,port),opipno(current,port));
dispatchtasksequence(newts);

I set "Specific Itemtype" in "break to requirement" before, but it was wrong.
Now I don't know how to set the code in "break to requirement".

Li,

have you set the capacity of your transporter to 2?

Further please read the manual and the following post: http://www.flexsim.com/community/for...read.php?t=718.

I hope it makes everything a lot clearer, because from your example I think you are thinking in the wrong direction.

Hi, Li, I tried it, use the following code:
treenode ts = createemptytasksequence(centerobject(current,1),ge titemtype(item),0);
inserttask(ts,TASKTYPE_TRAVEL,current,NULL);
inserttask(ts,TASKTYPE_FRLOAD,item,current,port);
inserttask(ts,TASKTYPE_BREAK,NULL,NULL);
inserttask(ts,TASKTYPE_TRAVEL,outobject(current,po rt),NULL);
inserttask(ts,TASKTYPE_FRUNLOAD,item,outobject(cur rent,port),opipno(current,port));
dispatchtasksequence(ts);

I found that only the first item is not correct picked(I mean it is always picked firstly despite its priority). Others will always be picked according to their priority.

The transporter's capacity only 1, it's my set.
So I think the tasksequence(Travel/Break/load/travel/Unload).
I want to do a decision in "break to".
It can transfer in priority at the active tasksequence.
Is my idea wrong? Or other methods?

Li,

I don't completely understand what you want. If you have a capacity of one, the breakto task will not work because there can only be one product in your transporter.

If the problem is that you have 2 products waiting to be taken away and 1 has a higher priority than the other, then you have to use preempting. You asked that question before: http://www.flexsim.com/community/for...read.php?t=659

So please explain better what you want.
