Presently, no uniform methodology of identification of optimal costs of construction of gas distribution networks is available. The amount of work, and, hence, its cost, are identified empirically; therefore, they are insufficiently substantiated by feasibility studies. At best, the problem of optimization is reduced to simple examination of various options.
The problem to be resolved by the method of search optimization may be stated in the following manner:
Two consumers are to obtain access to the gas supply. Their positions in the arbitrary coordinate system are available (; ). The high pressure gas distribution line of a gas distribution network is located at some distance from the aforementioned consumers. It can be represented as follows: = +. Gas control unit installation is required to assure gas pressure reduction.
Goal 1: positioning of a gas control unit to assure the lowest possible cost of the gas distribution network construction.
Goal 2: solution to the above problem turns more complicated, if the line of the gas distribution network required to connect the designed gas pipeline extension is long. In this case, besides the identification of the optimal coordinates of a gas control unit, it is also necessary to find the point of connection to the gas control unit, for the cost of the gas distribution network to be as low as possible.
Goal 3: some sections of gas distribution networks pass through or over natural or artificial barriers. In the event of such restrictions, the search for the optimal point of connection to the gas control unit turns more labor-intensive and challenging.
To sum up the above statements, the authors demonstrate that rational design of gas distribution networks brings essential economic benefits.
