Abstract

Merchant operations is an approach to manage commodity and energy conversion assets modeled as real options. Firms operate networks of such assets, e.g., multiple wind or solar farms that generate electricity at different geographical locations, may be coupled with local grid-level energy storage facilities, and are connected to various wholesale power markets via capacitated transmission lines. The corresponding models are typically intractable. This work describes methods to compute approximate operating policies and assess their optimality gaps for such models. These approximations extend techniques developed for models of single commodity and energy conversion assets.

Integrated Risk Management in Supply Chains

Integrated Risk Management in Supply Chains examines supply chain risk management. The increased interest in the topic is due to a number of factors including the increased volatility of commodity prices and exchange rates, recent natural disasters, and the increased importance of multinational corporations. The motivation for risk management comes from a variety of sources: financial distress costs, managerial incentives, and other important reasons discussed in the remainder of this book. Understanding the motives is important because they provide insights into which risks should be managed and how a firm’s risk management operations should be organized.

The first part examines Buffering Supply Chain Risk with Operational Flexibility and deals with uncertainty in the form of routine variability, which includes fluctuations in demand. Part 2 reviews Supply Disruption. Both the preponderance of natural disasters and huge economic swings can cause extreme challenges across the supply chains. Although these types of risks are rare, they are highly consequential and buffering is insufficient to mitigate them. Instead, firms facing these risks must engage in contingency planning and must maintain redundancies in the system. This is why contingency planning is on the interface of operations and finance. Part 3 looks at Commodity Price Risks, which includes five papers on managing price risks – the first three papers are fundamental in that they ask “when” and “how” firms should manage price risks with hedging and how hedging affects operating policy and the remaining two papers examine the best practices in specific industries.
