I've used EA for developing programs, but now I need to use it for trying to simulate a business process and check if it's convenient or not.

My example for the business process is the following one: I need to run a service in a server and I've two possibilities:

  • Buy a server with an initial investiment, and then paying the housing;
  • Use an amazon EC2 service, and pay for hour.

I model the service as something that every day gives a number to me, I multiply the number with a custom parameter, and I obtain the money that I gain that day.

I want to model the process in order to check what's the best alternative. I'd like to run a simulation instead that make calculus by hand (real process that I want to simulate is similar but more complicated).

How can I start to model it? Which kind of diagrams I need to use? and how can I run the simulation by setting parameters (investment, cost for hour and so on) so I obtain the result that allow me to choose which alternative (and parameters) give the best gain to me?

This explains a lot, thanks.

Ok thanks for your replies.

Uml Process / Use case with optional steps
« on: December 07, 2016, 07:15:42 pm »
I want to draw an use case for closing a program.

If I select the close button, the program shows a dialog ask for confirmation and if confirmed closes. This happens when no documents are opened.

But if one or more documents are opened, I want to show before the dialog for closing the program, dialogs for saving and discarding opened documents.

Do I need to create different use cases (one for closing programs with no document opened and another one for closing program with opened document), or there's a way to define optional steps in an use case?

If you must combine different documents, it's better to create a master Word document, and then link other document to it. At the end you'll obtain a document that's the merging of them, that is automatically updated when one of child document is updated, and it's also possible to define the style in the master document

General Board / Save image with background
« on: November 15, 2016, 07:46:36 am »
I've create a new theme that I want to use for saving diagrams.
I've set a color for the background, but when I save the diagram with Publish->Save Image->Save to File, the background is white.

How can I save the diagram with the background that I've set?

Suggestions and Requests / Real-time style color change

I need to change colors of uml components for a diagram. I use the Fill Color button in the Style group of Layout tab.

Until I select the color, the uml diagram element is not updated. It will be wonderful if the color of selected element(s) can change when hovering on a color of the palette. This way I can select the right color in a more straightforward way, without the necessity to select them manually every time, saving a lot of time.

General Board / Change language of all elements of a package

I've a project where there are many uml classes inside a package. The problem is that the language is wrong for all of them. I have to change classes language from Java to C++ for all of them. How can I automate this task without changing every class manually (they are almost 500)?

Suggestions and Requests / Choose diagram theme when saving image
« on: October 30, 2016, 06:06:58 pm »
Often I need to save diagrams to a file. I use Publish->Save Image->Save to file.

The problem is that the diagram theme that I use for drawing is not the same that I want to use when I save an image, so I have to switch every time the theme. I'd like to have an options for setting the theme of a diagram when saving it, and/or the possibility to select it in the Save Image dialog (maintaining the last one chosen perhaps?).

Is it possible?

General Board / Set page color
« on: August 22, 2016, 01:37:37 am »
Hi. I want to create a cover page similar to the attached one.

In order to to this, I need to fill the entire page with a background color. I've set page margins to 0, but I cannot fill exactly the page. I've created a table with a single cell but I cannot fill the entire page with the table cell. If I try to enlarge the cell to the entire page, when the bottom border almost reaches the bottom part of the page, a new page appears.

What's the most intelligent way to set a background color for the page?


I need to export diagrams in a vectorial format, like SVG or EPS. Considering that they are not supported, I'd like to create a plugin for creating the SVG of a diagram (it should be not so difficult, considering that an SVG is a text file, and that at the moment I need only vectorial data and my diagrams don't have bitmaps).

I'd like to know how can I access in a script (i.e. javascript) to layout data of a diagram. I.e. I'd like to have the position and the dimension of every element in a diagram. Is that possible?
