如何在CPLEX OPL中輸入3索引參數的數據？

Question

我在我的問題中有一個變量X [i] [j] [k]。如何在CPLEX的.dat文件中爲此輸入數據？

允許假設我= 2，J = 2，K = 3

供應商1（I）分量1（j）的20 30 40 組分2 50 20 10 供應商2組分1（j）的20 80 40 組件2 10 20 10

Answer 1

你可以看一下例子

CPLEX_Studio127\opl\examples\opl\models\YieldStochastic 

在那裏你會在看到的.mod

{string} classes = {"First", "Business", "Economy"}; 
int capacity[classes] = [37, 38, 47]; 

// Planned periods 
range periods = 1..3; 

// 3 scenarios are studied with their corresponding probability 
range scenarios = 1..3; 
float probaScenarios[scenarios] = [0.1, 0.7, 0.2]; 

// 3 pricing options for each class and period 
range options = 1..3; 
int priceOptions[periods][classes][options] = ...; 

然後在.DAT

priceOptions = 
    [[[1200,1000,950], 
    [900,800,600], 
    [500,300,200]], 
    [[1400,1300,1150], 
    [1100,900,750], 
    [700,400,350]], 
    [[1500,900,850], 
    [820,800,500], 
    [480,470,450]]];
