RE: [SysML Forum] Ports and (Internal) block diagrams

wadlerdan...@hotmail.com (Daniel Wadler) — Sun, 08 Nov 2009 06:11:09 UT

i would use a single port on A and a single port on B.
However, for the provided and required interfaces i would use the interfaces of ports p_B1 and p_B2 as superclasses for the interface of p_B (iow i_B1 and i_B2 are superclasses of i_B). the same for ports p_A, p_A1, p_A2\i_A, i_A1 and i_A2.

RE: [SysML Forum] Target of CallOperationAction

dobre.dra...@gmail.com (Dragos DOBRE) — Fri, 06 Nov 2009 15:56:55 UT

Hello,

I think you can do that by adding a parameter to your operation with the
wheel type. When you call your operation you give the rigthFrontWheel part
value to your parameter.

Ralph
Many thanks for your help here. Hopefully you will see my other post where I
have submitted a worked example of this in MagicDraw, and a write up also.
I would have liked, and still would like, to try this with Artisan also.
Unfortunately the free Uno edition is not really supported, so I couldn¹t

Hi all
I am, for my night job, working on a dissertation aimed at creating a
Network Design Modelling Language (NDML). Some of you have seen my earlier
posts about instances, and no doubt enjoyed the related discussions :-)
I felt that it would be useful to anchor such discussions with an "real
world" example, so I have created one using MagicDraw and attached it, and a

Hello,
I am a little bit new on sysML, I hope you'll forgive me to query on a
basic question.

I try to modelize a system, allocated on several centres. Centre A and
centre B.
Centre A is divided into 2 parts : Part A1 and Part A2
Centre B is divided into 2 parts : Part B1 and Part B2

On a logical point of view, A1 communicates with B1 and A2

Target of CallOperationAction

Hi,

i modelled a procedure of my system through an activity diagram. i use
a callAperationAction and as target, i want to chose an instance of
block of my model. i explain:
Example: my system is a car with four wheels ( rigthFrontWheel,
rigthBackWheel, leftbackwheel, leftFrontWheel), to model this, i draw

Block Definition Diagram query

thedemonlov...@gmail.com (Vikas) — Tue, 27 Oct 2009 23:38:19 UT

Hi,
In my Block Definition Diagram, the input parameters and the return
type of a Operation must be XML. The input parameters and the return
type may have different XML structure (i.e they use different XML
schema).

What is the best way to model this ? If I use primitive type "String"
for input and return type this doesn't capture the structure of the

You can use a SysML Use Case diagram and use the actor element with

to model stakeholder's in SysML.

Laurent,

If you didn't understand my previous comments or the SysML FAQ regarding
this topic, I recommend that you carefully read Russell Peak's 22
October response to this thread, in which he recognizes "the need to
support instances explicitly" and notes that "the OMG SysML Revision

I also would be interested to know more about why this is a huge "design
flaw". Can you please elaborate Cris?

The assertion in this thread that "you cannot assign value to constraint
blocks because there is not instance semantics" is actually not correct.

In this case, SysML replaces the need for instances by the concept of

Actually, it's more ironic than odd. During the time when the two SysML submission teams were actively competing Instance syntax/semantics was a key design issue on which they seemed to agree at a high level. Indeed, the SysML Partners planned to incorporate Instance syntax/semantics in the next (beta) version of their specification.

Hello Ray,

As a matter of fact what you want to do is possible with Artisan Studio (see
Artisan Studio Uno for a free version). You should read the SysML tutorial
from Artisan

Nathan, it seems to me that we are running into the same problem - in your
case with ports and in mine with composite parts. The question seems to be
if these aspects of a block are treated as part of the block (class)
definition and, therefore, are included when an instance is created. It
seems to me to be a significant flaw if this is not how it works.
