The optimization routine requires the designation of seven types of optimization data, viz.:

•Pipe Grouping

•Cost Functions

•Cost Function Assignments

•Candidate Sizes

•Load Cases

•Pressure Constraints

•Pareto Optimal Parameters

Some of the optimization data are directly associated with elements of the system model, and are also saved as part of the system data. This includes:

- The group no. that each pipe belongs to (Pipes not to be seized belong to Group O).

- The cost function each pipe is assigned to.

- The load cases (outputs) up to 5 at each node for which the system has to be designed/optimized.

- The minimum pressures – up to 5 at each node, which the system has to comply with.

- The efficiency of each pump, for purposes of energy cost calculations.

- The % of time each pump runs under the up to 5 different load cases.

- Information related to tank sizing.

Other optimization data that cannot be directly linked to system elements are saved separately in an optimization file, and includes:

- The candidate pipe sizes for each group.

- The Pareto Optimal tolerances for cost and pressure.

- Information related to tank sizing.

Both the system related and optimization specific data can be edited in the spreadsheet editors provided. The system related data can also be entered/edited in the Albion environment, either individually for each link/node, or by using the selection options available.

Cost functions for pipe installation, pumping energy and storage tanks are entered/edited/saved in the Cost Data module of the program, and also form an integral part of the data requirements for optimization.
