Some models of risk pooling
One of the primary challenges in supply chain management is matching demand with supply. Having too much supply leads to high inventory related costs, while insufficient supply reduces sales. This challenge has increased over the last few decades, mainly as a result of increasing product variety while product life-time has been decreasing. This dissertation addresses this challenge, and is structured as follows. In Chapter 1, we discuss the different aspects of managing product variety. One way to mitigate the effects of product variety is through the use of risk pooling, which is the common theme of the research. This concept is then discussed and different examples of risk pooling in Operations Management are given. Chapter 2 analyzes different models of inventory management when different products share common components in an assemble-to-order environment. The concept of assemble-to-order (using local assembly) is combined with cheaper, but less flexible, make-to-stock (using assembly in a low cost country) in Chapter 3. Another form of risk pooling is to share inventory among different retail outlets. The concept of lateral transshipment with local decision making is analyzed in a game theoretic setting in Chapter 4. A new method of taking derivatives of the expectation of positive terms, which is utilized in all previously described models is illustrated in Chapter 5. Finally, Chapter 6 outlines recent and current research building on this thesis.
