SeweCad V8i can perform an Constraint based Automatic Design. It uses a design algorithm that attempts to minimize pipe size and excavation, which is typically the most expensive part of installing sewer piping and structures. My question is, What kind of algorithm does SewerCad use for to perform an Automatic Design?, I mean, what is the name? Is heuristic? Where can I find information about it? literature, books, etc.
Thank you for your answers.
It looks like this question was already answered in this previous post:

Was there something else that you still had a question about?

thank you for your answer,
yes, I need more information about it, the last time, they sent me a topic called "Design Priorities", and in this document don't talk about design algorithm that SewerCad uses for to perform an Automatic Design. I want to know specifically about the algorithm used in this program.
Thanks again
Mark,
I read the document again, I understand the priorities that the algorithm used, also you tell me that the design problem is solved with an iterative process. I mean, the design alghorithm is an heuristic method that solves the problem throught an interactive process, using the priorities are in the document.
I will try to find more information about the heuristic method used.
Thanks for your answer and for you time.

Jesus,
You aren't likely to find more information. It is just a set of checks and adjustments that mimic what a practicing engineer would do when laying out a gravity conduit.
It is not a formal optimization method like GA or dynamic programming and doesn't explicitly consider costs but we are confident that it gives a reasonable set of pipe sizes and invert elevations.
An experienced engineer can probably make some adjustments to come up with an even better solution but it gives you a good starting point. With our visualization tools, it's easy to make adjustments and simulate.

Thank you for your answer Dr Walski,
In the SewerCad v8i User guide says that the design algorithm attempts to minimize pipe size and excavation, which is typically the most expensive part of installing sewer piping and structures, that somehow is a method of optimization.
You told me in a last post, that SewerCad uses an heuristic method, for that reason I was curious about this method and algorithm.
This is the forum where I manifest what I said above:
If I'm not the right thing I appreciate is corrected.
Thank you again.
Regards
someone has another review?
I think we have given you as much information about the method as we can. The design priorities document that I uploaded for you above is what we have that describes heuristic design algorithm that SewerCAD uses. As Dr. Walski stated, "It is just a set of checks and adjustments that mimic what a practicing engineer would do when laying out a gravity conduit.".
thanks for your answers.
This information is very useful for me.
