yard oepration

[Shahin Gelareh]

suppose there is only one vessel calling port on monday, then after the operation stopped from Mondat to sunday we do a relocation inside the yard.
we use as transport resources the same Trucks which was dispatched by TruckGang to relocate the boxes from the import area to the export area.
(does nto need to be logical but just excercise!)

Then there is an error like the following which is hard to understand. Moreover, the containers are stacked somewhere very irrelevant along an straight line.

First, my question is how to interpret the error message and how to do the oepration?

I attached the model to this post.1513

There seems to be a problem with specifying an Area as the "To Block" in the Relocate Operation.

To fix this error, you should use multiple relocate operations, one for each block in the area you want to move to.

Thanks, I tried your suggestion.
There seems to problem still.
I set from Monday 7 to sunday do the relocation from export"i" to import"i". Also ading Gang as transport resource.

the error says "NULL was given a task sequence but is not a Dispatcher".

Well, the problem is that I cannot udnerstand the error message otherwise I would try to solve it by myself.

It would be much easier to tell you what is wrong if you would post the model.

[Shahin Gelareh]

Thanks I attached it here.
I would very much like to learn how to interpret and understand the errors if possible.is that documented anywhere?

regards,

[Shahin Gelareh]

any hope for support? :)

You didn't specify a "Transport Resource" on one of the Relocate operations in your yard planner.

Hence, "NULL" (an unspecified resource) was given a task sequence (the relocate operation).

Also in your model, you are having exceptions thrown because you didn't specify an "Unstacking resource" in many of your Relocate operations.

You need to specify the required information in the GUI for the relocate operations if you want them to work.

[Shahin Gelareh]

Thanks for support.
It is solved. but according to the page 133 of manual, even if leaving the unstacking blank still the default values are supposed to be considered.

[Phil BoBo]

Thanks for pointing that out. We'll look into it.
