ExtendSim AT is designed for modeling and analysis of complex systems. Adds advanced discrete event and discrete rate modeling technologies to ExtendSim OR, such as:

bullet Scenario Management - a highly flexible framework for experimentation and analysis. Create best-, worst-, and typical-case assumptions for input values. Then recall each of these scenarios to see how the model behaves under different conditions.
bullet Advanced Resource Management (ARM) - an integrated system for organizing resources, distinguishing between them, and allocating them throughout a model. ARM is a method for defining complex resource requirements that incorporates a flexible set of rules for how resources get allocated.
bullet Rate-based functionality for modeling bulk systems, such as packaging lines, chemical processes, or network traffic. Use it to specify rates of flow for any high volume or high speed system, then delay and route the flow using attributes, constraints, and rules.
bullet Query Equation capability for ranking database records is indispensable when a database holds information that is required for making decisions in a model. For example, use this sophisticated tool to search a database table for the best record.
bullet An Add-In for Excel that allows you to completely specify a new ExtendSim database in Excel, including parent/child relationships, cell randomization, named distributions, and more, then export the database for use in ExtendSim models.
bullet Import fitted distributions directly from the included Stat::Fit distribution fitting package from Geer Mountain Software.
bullet Plus, all the features and capabilities of ExtendSim OR


"I looked closely at the ExtendSim discrete rate blocks and documentation. I find this to be a phenomenal piece of development. I don’t think it is an exaggeration to say that the discrete rate block set will be the best extension of the ExtendSim environment ever released by anyone and it is exciting to think about utilizing this capability in future models for my clients.
The ExtendSim Rate library is such a complete (approaching perfect) implementation that I feel compelled to be detailed in my review. It simply meets and exceeds all of (my) expected standards of ExtendSim blocks . . .

The architecture is truly elegant. From residence blocks defining rate sections, unit groups and unit conversion, basic (reasonable) flow rules that clearly define movement and recalculation, and of course the use of LP. I think you will find many users quickly grasping how cool this is and will be building it into models just because it is cool. The architectural vision behind this capability is just amazing. I love software elegance. I wish I could figure out how to do it in my custom blocks, and I have a deep respect for those who can actually pull it off.
It appears that all user levels of ExtendSim will be able to leverage it. A basic rate-based model can be built with only a minimal, intuitive understanding of the blocks, but there appears to be no limit to the depth/complexity/detail of a system that can be built in this construct (see elegance above). I think user diversity is one of the best measures for whether a block set is successful (useful) and discrete rate clearly meets this standard.
Even the icon animation is thoughtful in detail and usefulness. Thank you for not minimizing this in the development. 

My congratulations to Cecile and the rest of the ITI group for understanding the need and executing the capability absolutely right."
