flow shop scheduling problem using genetic algorithm in MATLAB

I tried a flow shop scheduling problem using genetic algorithm in MATLAB optimization tool box. I tried on a sample of 5 jobs, 3 machines flow shop scheduling problem using genetic algorithm. I am getting the right answer for the best indidual in the population . But I am not getting convergence even after 100 generations. I used the following data of processing times.[8,10,6,7,11;5,6,2,3,4;4,9,8,6,5].I am getting the Cmax(make span) as 51. I used the permutation crossover and permutation mutation operators and creation_permutation.m data type. please guide me.If I get convergence for small problems like this one, I can extend my work to a practical real world problem. please guide me.

Yes,I can guide you.
Instead of using the optimization tool box,you use my codes.As I have done for pure flowshop problem.
i have searched your Genetic algorithm matlab code for permutation flowshop scheduling but i didn't find it.

@fathi zahou: The nature of this forum is sharing problems and solutions. Contacting persons by email is not useful for this purpose. Publishing your email address here will increase the number of spams you get. So I recommend to delete your comment and post a new question.
@Jan thank you a lot.
i post my quesion
can you help me to solve my problem!
@fathi zahou: Maybe I can help you. You mention, that you have posted a question. So I assume it would be of your interest to post a link to your question.
I am a beginner, however I am sure I have not modified anything, Originally I put one question and nothing more
and this this is its link:

@fathi zahou: Sorry, this was my mistake. I've confused "fathi" with "faith". I've removed my explaination about removing questions.
okay,no problem
i'm really want someone to help me;could u help me and see my quesion,
it's about job shop problem using genetic algorithm on matlab.
I am nervous because I did not find a solution
I need halp my problem is scheduling parallel flow shop using genetic algorithem
