Assistant Professor Education Management Used the software for: 1-2 years ### "Great looking and advanced simulations" June 20, 2019 5.0 I am a teacher in university. I had never worked with simulation software before, so it was my first software of such type. FlexSim is just a whole universe, with it's own logic and rules. If you want to do BIG things with it - you have to understand all of these rules, accept them and change your own thinking to follow that rules (to think like FlexSim would think). I am a very advanced user of Excel, and Excel is a large universe as well. But now I am wondering which of them is bigger. Pros Great visualization makes it very pleasant to start learning; Lots of built-in features, Data import-export; Different modes (3D, ProcessFlow), where you can work simultaneously or independently; Strong statistics (distributions), that can be integrated on the models, collecting and presenting data; Anything you lack regarding the model or actor logic can be added as code snippets; Really basic models can be made in minutes Cons It becomes difficult to learn it when you go in deep. The really basic actions are easy and intuitive, like for kids. But when you get to something just little more complex - it requires a lot of additional knowledge. Little community tutorials. There are not many community samples and tutorials on youtube or in the web. Most of them are over basic functions - you probably will need to enroll a training. Review Source Response from Autodesk June 25, 2019 Thank you for your review, Dr. Sheludko! We're pleased to hear that you've enjoyed FlexSim's wide range of features and capabilities. It's true that complex systems can be challenging to model in any simulation analysis platform -- we try to make it as simply as we can, and welcome any additional feedback you have in helping us reach this goal. KL Kavan L. Engineer Food Production Used the software for: 1-2 years ### "FlexSim is a Great Tool" June 14, 2019 4.0 At the moment I use FlexSim to simulation the possibilities within a given confined space. I build models to represent a few different scenarios and demonstrate them to the team, so that leadership can make a decision on particular go/no-go criteria for a project. I use FlexSim to demonstrate possibilities that people in the viewing group might not have even considered, and generate new conversations regarding what's possible and which direction to go. Pros What I like most about FlexSim is the software's ease of use. I did trials on several other simulation software and FlexSim came out on top for me. It was intuitive and just simply made sense when building models. After the initial training I built a simulation model to represent one of our biggest production plants. Having that 3D visual was key in explaining processes to the rest of the team, and I could make real time changes in the model to work through those "what if" scenarios. The intricate details and the ability to allow viewers to see a different perspectives is actually very eye opening. Cons What I like least about the software is the lack of floor levels that are representative of actual buildings. This might be minor, but I wished there were options for prebuilt stairs and different floor levels. Stairs and floor levels are common in plants, hospitals, airport, etc., so why not give the user those items in the toolbox. For example, if I wanted to simulate a building with three floors, with people walking from one floor to the other (not necessarily one above the other, otherwise we wouldn't be able to see the operation on the other floors), using a second and third elevated floor plan. Hopefully that makes sense. Alternatives considered [AnyLogic](https://www.capterra.com/p/95940/AnyLogic/)[Simio](https://www.capterra.com/p/110473/Simio/) Reason for choosing FlexSim It was more intuitive, more powerful, and provided me what I needed to simulation the systems within my industry with relative ease and accuracy. The other products got confusing very quickly and was time consuming. Review Source Response from Autodesk June 18, 2019 Thanks for your review, Kavan! We're glad that FlexSim came out on top in your evaluation, and the ease of use and visuals have been helpful. I have some good news for you -- the latest version of FlexSim (19.1) has multi-floor support and elevator banks! Let's talk offline and I can share some videos with you. Kate G. Senior Process Improvement Specialist Hospital & Health Care Used the software for: 1-2 years ### "Very pretty, but too hard to use if not in it often" December 15, 2025 3.0 I really wanted to try like it but ended up not choosing it for the simulation software my company uses. Pros It was a very pretty way to show simulations that have real potential to be useful to show off to champions and project sponsors. Cons I tried very hard and have a lot of background in simulation and couldn't get to a point where it made sense for our company to use it, I wasn't confident in the mathematical rigor of the simulations, and couldn't train my coworkers to use it, Review Source DC Dhuey C. Principal Engineer Food & Beverages Used the software for: 6-12 months ### "Long time Simulation practitioner" June 20, 2019 5.0 We are using FlexSim to evaluate a new production line, everything from equipment capability, line control logic and staffing. The data from the simulations has enabled us to reduce staffing, and equipment requirements. Pros Very easy to build a simple model with the 3D Objects. The 3D objects have enough hooks in place to deal with more complex situations as well. There is no need to know programing language. The software is a tool that can be used by both the novice and experienced modeler. Cons The users manual is a bit hard to follow, and missing some information. I would like more options for flow item shapes and shapes for resources. Reason for choosing FlexSim I did not make the decision Switched from [ExtendSim CP](https://www.capterra.com/p/124174/ExtendSim/) Better 3d visualization of the process, data has the ability to be better tied to the asset, vs putting everything in tables. Review Source Response from Autodesk June 26, 2019 Thank you for your review, Dhuey! We're glad to hear that you've found FlexSim capable of both simple and complex simulation models. Let's connect offline and discuss some of your suggestions for item shapes -- I'm sure our developers would appreciate the info. VB Vincent B. Analytical Decision Specialist Management Consulting Used the software for: 2+ years ### "All purpose simulation software" June 13, 2019 5.0 I simulate mining sites (surface and underground), mine-to-port logistics, food and beverage plants, airport baggage handling systems, mechanical workshops, manufacturing assembly lines, distribution centers, distribution networks, supply chains, rail and road transport systems. Very visual although visual can be turned off or ignored, very efficient flexscript language, I can simulate a wide range of industries with a single tool. Pros Stunning interactive 3D graphics, full programming capabilities (no external compiler needed), links with Excel and SQL databases, ability to customize anything and develop reusable libraries Cons Limited cloud interactivity, too many new important features appearing, company focus seems to be on Process Flow module which is more complicated to use by programmers and less object-oriented Switched from [AnyLogic](https://www.capterra.com/p/95940/AnyLogic/) I used Flexsim before, changed job and learned Anylogic, changed job again to become consultant. Now I have the freedom to choose, I prefer Flexsim!! Review Source Response from Autodesk June 14, 2019 Thank you for your review, Vincent! We're glad that you're enjoying our visuals, database connectivity, and customization options. Can we find a time to connect offline and discuss some of your feedback on our Process Flow module? pL pierre-yves L. software engineer Transportation/Trucking/Railroad Used the software for: 2+ years ### "The real possibility to simulate anything" June 14, 2019 4.0 We use Flexsim to develop automatic train traffic regulation algorithm. We are now extending the trains flow to the passengers flows because we want to improve the quality of service. Pros Flexsim offers a wide range of predefined simple object that can act independently. Each object can easily be modified. These concepts allow the user to build any simulation project by putting these objects together. Cons The variety of objects and the abundance of options for each object may be a drag on efficiency of the project development. You need to have almost a complete skill with Flexsim to find the easiest way to achieve your goal. Alternatives considered [Simio](https://www.capterra.com/p/110473/Simio/) Reason for choosing FlexSim FlexSim appears to be the best choice in term of easy to use, cost and capacity to develop a full custom simulation. Review Source Response from Autodesk June 18, 2019 Thank you for your review, Pierre-Yves! We're glad to hear that you've made good use of our standard object library in your models. We do pride ourselves on being as easy-to-use as possible, but you are correct -- simulation can sometimes be difficult and require additional experience in the software. PD Patrick D. Senior Project Engineer Electrical/Electronic Manufacturing Used the software for: Less than 6 months ### "Cool Visuals But Not Sure on Implementation " December 20, 2022 4.0 My overall experience with FlexSim has been basically of uncertainty with it being a new software that I do not find easy to use and has not been implemented with my company. The training was disappointing as there were technical issues and we “hit the ground sprinting” from my experience of not knowing how to start a new project and then too large of a group to get the specialized assistance needed. Pros What I liked most about this software was what I saw in a presentation that was able to simulate a logistics warehouse and was very helpful and informative for future clients to see actual 3D modeling showing more than be stated just in words. Cons What I liked least about this software was that the training seemed to not be directed at my industry as the first few days were very random and there was not a good introduction on how to use the software from a very basic understanding. Alternatives considered [AutoCAD](https://www.capterra.com/p/265024/AutoCAD/)[AutoCAD LT](https://www.capterra.com/p/2011/AutoCAD-LT/) Reason for choosing FlexSim From my understanding, we chose FlexSim over alternative projects as we were impressed with their presentation and abilities with a new modern product that offered free training as well. Review Source SM Samuel M. Research Assitant Education Management Used the software for: 2+ years ### "Simulation made easy and intuitive with FlexSim" June 13, 2019 5.0 Great software to introduce Simulation and show-off 3D models. Pros Not only does FlexSim has great 3D graphics potential compared to other software applications in the market, but also its simplicity and intuitive modeling structure gives it an edge from the rest. Cons While FlexSim is mostly built for an easy point and click modeling approach, modeling complex decisions that require deep programming conditions is not very straight forward as compared to other applications. Switched from [Arena PLM](https://www.capterra.com/p/6101/Arena-PLM/) FlexSim has more learning support for education, its simple and very visual, making it attractive for undergraduate students. Review Source Response from Autodesk June 17, 2019 Thank you for your review, Samuel! I'm glad you enjoy our graphics and intuitive modeling structure.

HP Hill P. Managing Director, Supply Chain Practice Food & Beverages Used the software for: 2+ years ### "Extraordinary tool and support" June 13, 2019 5.0 Truly excellent in every dimension of technology, service and accounting. Pros Versatility. There is almost no scenario that we haven't been able to support... But it goes beyond the tool; the can-do attitude and creativity of the FlexSim consultants is critical as well. I can't say enough good things about their willingness to find ways to model the variety of scenarios we encounter. FlexSim has something for both sides of the brain--visuals are spectacular--almost beautiful. Rigorous performance quantification of complex systems completes the picture. Cons It's the flip side of versatility--complexity. The tool is so incredibly complex that it is hard to envision every being independent. I don't know if this is a criticism or just a reality. Review Source Response from Autodesk June 18, 2019 Thank you for your review, Hill! We really appreciate the kind words about our support, capability, and visuals. You're absolutely right -- simulation modeling can get complicated! (But we're always trying to make it as easy as possible.) IK Igor K.
