We study the facial structure of a polyhedron associated with the single node relaxation of network ow problems with additive variable upper bounds. This type of structure arises for example in network design/expansion problems, in production planning problems with setup times. We rst derive two classes of valid inequalities for this polyhedron and give the conditions under which they are facet...

We study the facial structure of a polyhedron associated with the single node relaxation of network flow problems with additive variable upper bounds. This type of structure arises, for example, in production planning problems with setup times and in network certain expansion problems. We derive several classes of valid inequalities for this polyhedron and give conditions under which they are f...

This paper proposes a mathematical model for transmission expansion employing optimization method with scenario analysis approach. Economic transmission planning, on the other hand, seeks investment opportunities so that network expansions can generate more economic benefits than the costs. This approach can be used as a decision model for building new transmission lines added to the existing t...

In network investments, much of the real options value may reside “in” identifying the proper configuration to develop, in terms of the timing and sizing of its deployment. A longer-term perspective, with a treatment of uncertainty that moves beyond simply increasing deterministic specifications, has the potential to improve the design of networked infrastructures, such as power transmission ne...
