"Very easy to use and learn. Anyone can learn in a few days."

5/5

What do you like best about ExtendSim?

The documentation of this software is so complete and detailed. There is more than 1000 pages of pdf file explaining every bit of how the software works with tutorials. Everyone can start using it immediately by just looking at documentation and example model files. Much better than Arena! You can create a relational database unlike Arena and model really complex systems easily. Can also simpThis is a very underrated software since they don't do much advertising.

What do you dislike about ExtendSim?

Almost no 3D capabilities. But if you don't need 3D animation this is the best software to use. Other than that nothing much to complain. It can be hard to model warehouse models. Review collected by and hosted on G2.com.

"ExtendSim review"

3.5/5

What do you like best about ExtendSim?

It has great capability both for academic and professional purposes. Review collected by and hosted on G2.com.

What do you dislike about ExtendSim?

The UI/UX isn't quite modern and intuitive. Review collected by and hosted on G2.com.

Recommendations to others considering ExtendSim:

It was a great tool to work with, hence I do recommend it. Review collected by and hosted on G2.com.

What problems is ExtendSim solving and how is that benefiting you?

I used ExtendSim in an academic environment, so basically, it was used to reinforce the concepts of Production Planning and Control. One of the projects consisted of evaluating the Assembly efficiency with the simulation of the whole factory layout in a realistic ExtendSim model. If the assembly operations continue to run smoothly without any problems like the unavailability of parts operators, tools, machines, fasteners, etc, then the production system can produce the required quantity.

"Satisfied with simulation and results"

4/5

What do you like best about ExtendSim?

Alloting each operation as a block and making changes to its properties to get the final result. Also various features like conveyor and transport blocks help to give better understanding of the flow Review collected by and hosted on G2.com.

What do you dislike about ExtendSim?

Can become complex sometimes on searching for specific requirement like how to batch parts up before simulation, but can be sorted if searched through. Review collected by and hosted on G2.com.

Recommendations to others considering ExtendSim:

A good initial simulation tool to understand the processes and make further decisions while working in a project or shop floor. Review collected by and hosted on G2.com.

What problems is ExtendSim solving and how is that benefiting you?

It's helping me with a group project on studying a production line in a factory, and how each factor can relate to a final result. Review collected by and hosted on G2.com.

"ExtendSim is an interesting tool for analysis. But more tutorials should be published for learning."

2.5/5

What do you like best about ExtendSim?

ExtendSim is very flexible to use. The guidance is very useful. Review collected by and hosted on G2.com.

What do you dislike about ExtendSim?

The license time for students is too short. The students can only use it in the university after it expires. There is less tutorial on the internet and less courses. Review collected by and hosted on G2.com.

"Event time-based solver"

4.5/5

What do you like best about ExtendSim?

Many solvers for all the post processing problems. Discrete event, continuous, agent-based, and discrete rate processes can be solved with ease. Review collected by and hosted on G2.com.

What do you dislike about ExtendSim?

Sometimes, specific to a task like event based and time based solvers doesn't fare well as opposed to all in one solutions by other industry leaders. Review collected by and hosted on G2.com.
