GA optimization

Hey,

 

I hope someone can help me with my problem.

 

I want to use GA to find a good sequence for the final assembly of cars.

I have about 1200 cars and 400 stations.

As chormosomes i want to use the car sequence (about 1200 cars).

 

I add a table with some intial sequences.

I have a method to compare the sequences. I use this for the fitness calculation.

 

For the fitness calculation i need the new car sequence as input for my methed. Where are the new sequence stored?

 

Is this the best approach or how would you apply GA on this problem.

 

thnx for your help

the GA changes the order (of rows) in your sequence-table, so you can read the new sequence directly from your table

Thanks for your answer Steffen.

 

I made a mistake, it is working as you told now.

 

I use the GA wizzard at the moment. How can I see how the new sequence (offspring) is created?

What kind of mutations, inversions, and/or crossovers are used in this process?

look in the wizzard - Objects - GA Control --> Selection

Dear Steffen

       I want to know do you have any approach to prevent < GA changes the order (of rows) in my sequence-table>.I just want to keep my table formal.

  

Thank you!

this will not work; it is just what the GA Sequence optimization does, it changes the order of your table and check the changes, based on the last order a new order will be created; so the GA needs some additional columns in the table to store e.g. the Information about the Chromosoms.

Thanks for your reply.I have another question about GAWizard.I can't keep the parameter in the GAWizard basic target.( GAWizard-Objects - GA Control --> Set->basic target),when I reset the GAWizard ,this set will be resetted " GAWizard.Seqloc.GASequence ."(or inform me 1 uesr have setted....),I don't know what shoud I do?

you need to define your parameters in the dialog of the GAWizard (tab define, minimum, maximum -- fitness values), the GAControl will take the data from the main menu.

Dear Steffen

      I'm sorry ,I don't make it clearly for my question.If I want to use GAWizard, GASequence and a processing table. I want to use this GASequence as my "optimise target ", optimize this table.But  (Object -> GA control-> GAtable)will be reset. picture1 is right,if I reset it become picture2 .I want keep this setting.What should I do?
