Hello,

I tried to combine MIP and CP using a hybrid model that combine both CP and CPLEX models together and it worked for small sized problems of vehicle routing problem.

Now, I am trying to combine both MIP and CP in one model ( relating MIP variables to CP variables such as:

1.relating x(i)(j)(k) which is a boolean variable which give value 1 if  j immediately  precedes i, to the interval variable tvisit[d in Demands][t in 1..m] optional (101>d.id>=1) size d.s which ) 

2. relating sequence variable to z(i)(k) which is a boolean variable which gives value 1 if client i is served using vehicle k)

so I want to solve the combination of CP and Cplex in one model ( using cplex or CP)

how can I do that?
