can you write the code for the opl model and data file for this:

The constraints ensure proper allocation $of$ resources: $d$

tonnes, maximum $50$ tonnes$(x_{ij}^{\text{r}\text{a}\text{i}\text{l}}),(10x_{ij}^{\text{r}\text{a}\text{i}\text{l}}50).$

Non$-$negativity:

$(x_{ij}^{\text{m}\text{o}\text{d}\text{e}}0).$ Minimize $Z=12x_{D1,C1}^{\text{r}\text{o}\text{a}\text{d}}+11x_{D1,C2}^{\text{r}\text{o}\text{a}\text{d}}+12x_{D2,C1}^{\text{r}\text{a}\text{i}\text{l}}+14x_{D2,C1}^{\text{r}\text{o}\text{a}\text{d}}+9x_{D3,C2}^{\text{r}\text{o}\text{a}\text{d}}+10x_{D3,C3}^{\text{r}\text{a}\text{i}\text{l}}+5x_{D3,C3}^{\text{r}\text{o}\text{a}\text{d}}+11x_{D4,C2}^{\text{r}\text{a}\text{i}\text{l}}+14x_{D4,C2}^{\text{r}\text{o}\text{a}\text{d}}$

Constraints

Flow Balance:

Total supply equals total demand: ${\displaystyle \underset{?}{\overset{?}{}}}{x}_{ij}=190$

The objective function $isto$ minimize the total transportation cost $by$ summing the product $of$ tonnes transported and theit

$cost$ across all routes and transport modes. This ensures the company achieves the lowest $logistics$ expense while meeting

constraints.

Depot Capacities:

$=(x_{D1,C1}^{\text{r}\text{o}\text{a}\text{d}}+x_{D1,C2}^{\text{r}\text{o}\text{a}\text{d}}50)$

$=(x_{D2,C1}^{\text{r}\text{a}\text{i}\text{l}}+x_{D2,C1}^{\text{r}\text{o}\text{a}\text{d}}40)$

$=(x_{D3,C2}^{\text{r}\text{o}\text{a}\text{d}}+x_{D3,C3}^{\text{r}\text{a}\text{i}\text{l}}+x_{D3,C3}^{\text{r}\text{o}\text{a}\text{d}}35)$

$=(x_{D4,C2}^{\text{r}\text{a}\text{i}\text{l}}+x_{D4,C2}^{\text{r}\text{o}\text{a}\text{d}}+x_{D4,C3}^{\text{r}\text{a}\text{i}\text{l}}+x_{D4,C3}^{\text{r}\text{o}\text{a}\text{d}}65)$
