So how to show that interactions may happen in parallel ? For representing parallelism, you would use a combined fragment introduced by the operator par. Graphically (see link), the combined fragment is represented as a boxed region in your sequence diagram, parallel sequences being separated by horizontal dashed lines (each of the slices would ...

The parallel combination fragment element needs to be used when creating a sequence diagram that shows parallel processing activities. The parallel combination fragment is drawn using a frame, and you place the text "par" in the frame's namebox.

I am new to UML sequence diagrams. I saw a few YouTube videos and a few tutorials such as this one. I have a system with multiple inputs, that can interact with the system asynchronously. For example, first the input 4 (out of 5), secondly the input 1 (out of 5), etc. How do I represent them in a UML Sequence diagram?

The parallel combination fragment element should be used when creating a sequence diagram that shows parallel processing activities. The parallel combination fragment is drawn using a frame, and you place the text “par” in the frame’s namebox. You then break up the frame’s content section into horizontal operands separated by a dashed line.

UML and Concurrency UML supports concurrency, and makes it possible to represent the concept in different kinds of diagrams. This article covers the three most commonly used – the activity diagram, sequence diagram, and state machine diagram. Note that the OCUP 2 Foundation level examination covers concurrency only in the activity diagram; concurrency in sequence and state machine diagrams ...

I would like to represent parallel messages in my sequence diagram. Typically, I would use a frame, then split it up with multiple operands, where each represents a concurrent operation. I can add a frame and rename it to “par”, but can’t figure out how to add the operand! I have searched in the forum here but came up empty-handed.

The parallel combination fragment element should be used when creating a sequence diagram that shows parallel processing activities. The parallel combination fragment is drawn using a frame, and you place the text “par” in the frame's namebox.

The basic notation for concurrency in sequence diagrams involves using parallel and concurrent regions. A parallel region is represented by a diagonal line that separates the sequence diagram into two or more parallel paths.

Parallel Actions When two actions happen at the very same time, you can make use of parallel actions. In your diagram, you first need to fork the flow. This is done with a thick black bar. Then, once the parallel actions have ceased, you merge your flow again with a similar bar.

I have a desire to illustrate parallelism in some sequence diagrams. When I try to do this EA shifts messages of other things around so I cannot get the illustration of parallelism in the diagram. It also breaks the activation boxes. Is there a way to illustrate parallelism in a sequence diagram with EA or is it inappropriate for parallelism to be in a sequence diagram? Thanks for any help on ...

I want to model an activity that involves processing several items in parallel. So to speak, I want to find a Activity Diagram representation for something like the following snippet / pseudocode: ...

The sequence diagram below is very similar to the activity diagram shown above, but now we see that the entire 3 phase analysis is eligible to run in parallel (as the ‘par’ Operator indicates), which consequently rules that DomeCameraAgent and its parts must be thread-safe, and so does the Gateway (we already suspected that it should after ...

How do you show parallel process in sequence diagram? In principle, the sequence of the interactions with your object is indicated by the vertical order of the messages. So how to show that interactions may happen in parallel ? For representing parallelism, you would use a combined fragment introduced by the operator par .

Flow Representation: Activity diagrams depict the sequence of activities, decisions, and parallel processes. Focus on Processes: They emphasize the overall flow rather than specific interactions between objects.

An Event-Driven Process Chain diagram or EPC diagram is a structured visual representation used to map out business processes in a clear and logical sequence. It helps organizations document, analyze, and optimize workflows by illustrating the relationships between key process elements such as events, functions (tasks), decision points, and ...

A PERT chart, also known as a PERT diagram, is a project management tool that helps plan and visualize the tasks involved in a project. It’s used to better understand and schedule the sequence of tasks, especially in projects with uncertain timelines.

This specialized ...

The problem is that I don't know how I can use UML diagrams for some distributed tasks. Firstly, I want to use Sequence diagrams and show the distributed components as actors.

Together, our findings indicate that during offline periods there are two parallel processes occurring: conserving of past memories through reactivation, and preparation for upcoming ones through ...

Imagine that a program spawns multiple threads to do the same kind of sequences interacting with different versions of objects. How do I model this in a sequence diagram? Say a thread is being replicated n number of times and this thread then performs some operations with objects A,B and C n number of times. How does one show it in a sequence diagram?
