IBM ILOG CPLEX Assignment

Word count 500.

• All optimisation analyses should be undertaken using IBM ILOG CPLEX. You can include screenshots from the software package, tables and charts to the report. These will not contribute to the word count.

Part B: Use of IBM ILOG CPLEX to solve a Minimum Cost Flow Problem instance.

Network picture files: This is the folder containing the network pictures, tailored and assigned to each student according to the table below. ( I sent you a document of it)

• Consider your individual data-sheet describing the scheme of a Minimum Cost Flow problem, including details on a Supply Network structure, costs, supply and demand data;
• Identify the appropriate model to be used among the examples of the IBM ILOG CPLEX optimisation suite and briefly recall its characteristics;
• Translate the provided individual datasheet into a dataset to feed this model (dataset to be included in your report as appendix A);
• Execute the optimisation process and export the results (results to be included in your report as appendix B);
• Provide a qualitative description of the optimal solution and the characteristics of the computational process;
• Based on the outcomes of the optimisation process, perform a managerial analysis to identify where to invest resources in order to improve the performance.

As regards supply/demand data for nodes, the following values will hold for all networks/data:

Note that on each arc you can read the labels representing: 

• UB/Arc capacity (black label)
• Unit Cost (orange label)
