WITNESS

I just imagine and WITNESS can do it

Kommentare: I was chief simulation engineer at a big automotive manufacturing plant and developed several projects. We initially worked with another solution (best seller) and after experiencing WITNESS we notice we could cut by half the time it takes for developing the same simulations...
I created a youtube page and now I share some experiences with my students. I am now a University professor and Consultant.

Vorteile:

The ability to handle very big simulations. 18 processes of a large warehouse including the movement of 30 trucks at the same time, people and trahsport vehicles. In addition to that, 10.000 lines of data with 60 columns were easyli processed. Another feature is 3D. I was able to simulate the exact complex movement of some transport equipment from automotive assembly line.

Nachteile:

I would like to see how to work with VIRTALIS in order to render my 3D features.

User friendly and easy to set up indeed.

Kommentare: Superb software that is not only best for simple models but also for complex ones.

Vorteile:

Witness has no doubt proved to be the outstanding simulation software and provide excellent ways of learning. It is really informative in a sense within a couple of weeks after taking help from some of its examples, I am able to make decent models myself. Effective tool that has provided engineering students with best simulation solutions so as to develop their more interest towards this awesome product. It's most fascinating feature is that it has excellent ability to compute wide range of data.

Nachteile:

I am not having much complains about this software. The only flaw of this software is that, sometimes it execution speed gets slow due to which users have to face a little bit difficulty. I would suggest, this software must have additional tools like data fitting and optimization otherwise one has to find other ways in order to get their needs fulfilled.

Simulation software with great learning curve. Definitely too buggy though.

Kommentare: I am able to use it to deliver bottle neck analysis reports to our customers, but working around and reporting bugs at the rate I do costs extra time and money

Vorteile:

The learning curve on the software is great. I was able to work through some of their examples and begin making decent models within a couple weeks. It also has deeper functionality that allows me to continue learning after 2+ years using the software. The code windows allow for complex logic for the more advanced users. The continuous flow elements have come a long way since first implemented and new features continue to be added with each release. The quantity of different types of built in elements and the number of features with each one is much greater than any other discrete simulation software I have ever used.

Nachteile:

What sets this product aside as a pro also leads to its main con. Its ease of use limits its functionality. All of its extra features lead to quite a few bugs that slip past the development team into their released product. In my 2.5 years, I have raised nearly 20 tickets with over half of them being confirmed bugs within the software. I am only one user out of a large pool using released versions of this software. I SHOULD NOT be finding this many bugs. I would urge the development team to stop over selling and under delivering on both features and schedule. Instead, set tangible targets for both schedule and features. We have been strung along on a new release for over 8 months before it was delivered. This should not happen.

Excellent with many features, from simple models to the highly complex

Vorteile:

3D functionality, support for multicycle machines and ease of initial use make this the perfect software for process modeling. New advances in 3D support also results in models that are easy for non-modelers (management) to understand and to have confidence in. The help functions and the Lanner website provide many examples and clear explanations. I should mention that I have written two books on the use of this software and teach its use at uni.

Nachteile:

While this software is pricey, it is balanced by the performance factors and ease of use. One would prefer to have more all-in-one support for the fitting of PDF's to empirical data, but there are many statistical packages that do this quite effectively.

Comprehensive and flexible analysis tool for a wide range of simulation applications

Kommentare: WITNESS has enabled me to provide a unique and valuable service to a wide range of clients

Vorteile:

Total flexibility in defining operating logic, great tools for debugging operating logic and excellent level of graphics to display model status and results

Nachteile:

Slow execution speed - would be wonderful if a user could compile a model to greatly improve execution speed
