Consider a graph G in which each vertex is either a supply vertex or a demand vertex and is assigned a supply or a demand. Such a graph G is called a power supply network. All the supplies and demands are nonnegative constant numbers in an ordinary network, called a steady network [1].This thesis introduces a parametric power supply network, in which all the supplies and demands are functions o...

We study the price competition of two supply chains with demand uncertainty. Each supply chain consists of one risk-averse manufacturer and one risk-averse retailer. We consider two cases: two competing decentralized supply chains and two competing integrated supply chains. We analyze the effects of the demand uncertainty on the supply chains’ expected profits. In the first case, we find that t...

Coordination is very important in supply chain management and it is one of the main factors in supply chain profitability. Bullwhip effect is one of the basic obstacles to achieve coordination in supply chains and reduction of this phenomenon has an important role in supply chain harmony. The other side, costs of supply chain can be mitigated and customer service level can be increased by reduc...

Nowadays, utilization of renewable energies for satisfying electricity demand has received more interest, and renewable electricity generation has been growing in the world. This study addresses the operational planning of a renewable electricity supply chain over a multi-period planning horizon. The purpose of this study is to maximize total profit and to optimize the operational decisions rel...
