The proposal is a partial market design in that it does not address the transportation...

In [9], De Wolf and Smeers consider the problem of the optimal dimensioning of a gas transmission network when the topology of the network is known. The pipe diameters must been chosen to minimize the sum of the investment and operating costs. This two stage problem was solved by application of the bundle method for nonsmooth optimization. This model does not reflect any more the current situat...
