The number of piecewise linear function in a OPL model

    Hello,

    I am Bobby. 

    I am familiar with OPL CPLEX for IP and MIP, but not CP Optimizer.

    Currently I will build a inventory model and it will involve several piecewise function in a model (i.e. one period has one nique function). My model will be large (minimum 12 periods). My question is: is there any limitation that CPLEX can handle regarding the number of piecewise functions can solve in a model since I can not get any information in CPLEX manual.

     

    Thank you very much for your kindness.

     

    best regards,

    Bobby

    Hi,

    you have some piecewise example in https://www.linkedin.com/pulse/how-opl-alex-fleischer/

    In the past I have used pwl with 1000 breakpoints

    regards
