Model:

int nbJobs = ...;

int nbMchs = ...;

range Jobs = 0..nbJobs-1;
range Mchs = 0..nbMchs-1; 
// Mchs is used both to index machines and operation position in job

tuple Operation {
  int mch; // Machine
  int pt;  // Processing time
};

Operation Ops[j in Jobs][m in Mchs] = ...;

Data:

nbJobs = 6;
nbMchs = 6;
//<Machine,Processing_time>
Ops=[
[<2,1>,<0,3>,<1,6>,<3,7>,<5,3>,<4,6>],
[<1,8>,<2,5>,<4,10>,<5,10>,<0,10>,<3,4>],
[<2,5>,<3,4>,<5,8>,<0,9>,<1,1>,<4,7>],
[<1,5>,<0,5>,<2,5>,<3,3>,<4,8>,<5,9>], 
[<2,9>,<1,3>,<4,5>,<5,4>,<0,3>,<3,1>],
[<1,3>,<3,3>,<5,9>,<0,10>,<4,4>,<2,1>],
];

But, I want to input this data  from Excel,  You can help me, please!

You may want to take a look at this and this chapter in the user manual. They explain how to input data from Excel. The big question will probably be how to organize your data in Excel so that it represents tuples. Since Excel does not have a tuple data type, you will have to find something else, for example two rows that define the (machine,processint_time) pairs (a pair is formed by the two values that are in the same column).
