List of discrete event simulation software Puns

Title. Beginning the process soon for a DES role I just dont know if I would like it. The one class I had over this was just not a good experience (for many people including myself), though it seemed interesting.

Anyone have experience that they could talk about? I'll be at a auto company

How much would I be expected to know when I start? I'm not too sure if I would enjoy an excessive amount of stats...

I am looking for tools/programming libraries/systems to allow me to flexibly carry out discrete event simulations for complex dataflow designs. Ideally, I'd be looking for:

• Ability to quickly and accurately model components, in particular: FIFOs, busses, and pieces of processing IP in terms of widths, depths, latency through the IP etc (standard protocols such as AXI-s even more desirable)
• Framework for connecting these primitives together to create a representation of a data flow design
• Ability to simulate data through the system
• Ability to carry out per-clock based modeling and update of the system's state
• Ability to easily collect per-clock point-in-time and aggregate statistics at the per-component level.

I have no issue with writing code and am happy to consider frameworks where I need to write some (or a lot of) code to do so. Ideally, a scripting approach via python or similar would be preferred as it's quicker to develop.

I've personally looked at SystemC and considered writing abstractions in Python but I thought I'd check with the subreddit in case there are obvious tools to do this sort of thing.

Help needed... Kindly comment your discord.

Are there any free discrete manufacturing simulators? I've looked at Simul8 and some others, but they come with a hefty price tag. There's also OpenModelica, but I can't make any sense of it and certainty can't find any examples for discrete manufacturing.

I'm on the verge of using sim.py or SimSharp to write my own simulations, but don't want to reinvent the wheel if I don't have to...

Hi Everyone,

I am new to this group and is very excited to learn about simulations from you guys. I am particularly interested in discrete event simulations and would like to know the proper theory behind it before i do the simulations. I am planning to use matlab for most of my simulation testing. Is there good discrete event simulation course(edx or udemy?) that you guys can recommend? Also, is Matlab a good idea or would any other programming language is more suitable?

Looking forward for your inputs and experience on this subject.

Hi Everyone, there was a post a few days ago about interviewing an IE or ISE. I took those questions and was requested to share answers (below). If you have any other questions feel free to ask them, and Ill get back to you. AMA theme etc...

Q: What are your main responsibilities as a Everyone wants to improve patient satisfaction ...?

A: I am a Discrete Event Simulation Advisor (my background is Industrial and Systems Engineering). My main responsibilities are to lead process improvement projects for the hospital I work at (from start to end). These projects responsibilities including creating a simulated model that predicts outcome to change in the system, pulling data for such models, and using project management skills to implement the change if its good.

Q: What is a typical day (or week) like for you?

A: A typical week consists of project meetings (giving updates, brain storming new ideas for improvement, working with others on the projects to develop process maps), doing observations of a process, setting some time to create the simulated models, and writing some SQL code to pull data or timestamps that are needed.

Q: What do you like most about your work?

A: The people – I feel as though hospitals typically employ rather caring people, and its very nice to work with people who have empathy as well as a common mindset. Everyone, whom I work with, wants to improve patient satisfactions – which means improving optimization, efficiency and utilization of doctors, nurses and other staff members’ time.

Q: What do you like least about your work?

A: Waking up- I’m not a morning person. Meetings with doctors are hard for me, bc they have a strict surgical schedule (often times starting at 7). This means that when meeting with docs, either it has to be a 6AM meeting or after surgeries/clinics around 5PM. Coffee helps a lot.

Q: What kinds of problems do you deal with?

A: I will sort my problems into two buckets, personal and broad. My personal problems are that I am not the best at coding – so often times when I write SQL code or scripts there is a lot of debugging and takes some time to do. The broad problems that I face, that are most transparent to someone wondering about the field is that people resent change. If you want to improve efficiencies or utilizations a change is often needed at a system level, thus the front line workers are often resistant. Its your job to empathize with their thoughts and persuade and sho

I am trying to model our companies supply chain to help argue the fact that the way some of our products are set up could be vastly improved. From experience I know that X number of computers that we receive from our supplier needs to be reworked, this is something simple like removing a 64gb hard drive and adding a larger 128gb hard drive. This is simply because we have more of the computers with the 64gb hard drive than the 128gb hard drive and it would take too long to wait for more of the computers with 128gb hard drive to come in so we find it better to rework it.

I am trying to model this under two different scenarios, 1) we receive both products as they are, track the rework costs and the additional inventory needed to perform the rework along with inventory levels of both. We always seem to have a lot more of the computers with 64gb hard drive in house due to more of these being forecasted. And 2) the product we receive in has no hard drive and we add it in just before we ship it out to the customer. Theory I have is average inventory levels would be lower due to a "safety valve" effect this would have on inventory.

With all this being thrown out there, is modeling this using the DES package, simmer, appropriate? Or are there simpler ways to skin this cat?

Hello everyone,

I'm aiming to do a less sophisticated python version of this: https://en.wikipedia.org/wiki/FlexSim

I'm thinking of using pygame for the 2D modelling, regarding to the 3D modelling I was thinking use blender but I found this: https://www.youtube.com/watch?v=aLr9TQOukcs the author recommend using panda3D or Unity instead of maya.

Google-ling around I found Unreal Engine is an option too.

I was looking for recommendations of someone with experience in Python animations so I could start working using the best tool.
Thanks!

I have a feeling that Clojure would be good for discrete event simulation, but even though I have had a good look around, I can't find some example code to get my (beginner!) head around. Can anyone point me towards some examples?

Hi all,

I was wondering if anybody knows of any generic frameworks for continuous time discrete event simulation that supports semi-Markov processes (gamma, Weibull, log-logistic) distributions on dwell times between state transitions. Are there any APIs for libraries in fast languages that can support this type of simulation? I've seen a bit in the stochastic petri-net literature but nothing that can handle non-exponential dwell times.

Thanks!
