Integrated Optimization of Procurement, Processing and Trade of Commodities in a Network Environment

Book Description
We consider the integrated optimization problem of procurement, processing and trade of commodities over a network in a multiperiod setting. Motivated by the operations of a prominent commodity processing firm, we model a firm that operates a star network with multiple locations at which it can procure an input commodity and has processing capacity at a central location to convert the input into a processed commodity. The processed commodity is sold using forward contracts, while the input itself can be traded at the end of the horizon. We show that the single-node version of this problem can be solved optimally when the procurement cost for the input is piecewise linear and convex, and derive closed form expressions for the marginal value of input and output inventory. However, these marginal values are hard to compute because of high dimensionality of the state space and we develop an efficient heuristic to compute approximate marginal values. We also show that the star network problem can be approximated as an equivalent single node problem and propose heuristics for solving the network problem. We conduct numerical studies to evaluate the performance of both the single node and network heuristics. We find that the single node heuristics are near-optimal, capturing close to 90% of the value of an upper bound on the optimal expected profits. Approximating the star network by a single node is effective, with the gap between the heuristic and upper bound ranging from 7% to 14% for longer planning horizons.

Book Description
This dissertation deals with three issues that are important to many firms, namely, volatile commodity prices, environmental regulations, and globalization. In the first essay I study the benefit and the coordination of inventory sharing when there are two existing channels for procurement, i.e., the spot and forward markets. I propose a method for sharing inventory such that the decentralized firms get the same benefit per unit of the sharing transactions regardless of whether the firm is borrowing or lending. The procurement cost gap between the centralized and decentralized cases is dramatically small by using this method. In the second essay, I analyze whether imposing carbon costs to retailers and consumers changes the supply chain design or social welfare. I consider three types of players who want to maximize different objectives and three kinds of competitive settings. Different from previous studies, I show that the supply chain design is changed significantly by imposing carbon costs especially when market competition is medium to high. In the third essay, I consider long-term / short-term strategies of multi-national corporations. For the long-term strategy, I show that the correlation between the exchange rate and the market demand in a foreign country affects plant location. For the short-term strategy, I show that manufacturers increase the inventory levels as the exchange rate of the country where the plant is located grows weaker. I confirm these results empirically using plant-level data of Korean multi-national corporations provided by the Export-Import Bank of Korea.

Poverty and Famines
Author: Amartya SenPublisher: OUP Oxford
ISBN: 0191037435
Category : Social Science
Languages : en
Pages : 270
Book Description
The main focus of this book is on the causation of starvation in general and of famines in particular. The author develops the alternative method of analysis—the 'entitlement approach'—concentrating on ownership and exchange, not on food supply. The book also provides a general analysis of the characterization and measurement of poverty. Various approaches used in economics, sociology, and political theory are critically examined. The predominance of distributional issues, including distribution between different occupation groups, links up the problem of conceptualizing poverty with that of analyzing starvation.
Commodities in Crisis
Author: Alfred MaizelsPublisher: Oxford University Press, USA
ISBN:
Category : Business & Economics
Languages : en
Pages : 336
Book Description
With the dramatic changes in the global political scene, many developing countries are re-evaluating their economic and political priorities. This reappraisal scrutinizes their dependence on specific commodities and the crisis into which this market has been thrown in the last decade. This work relates the main theoretical and empirical issues in the collapse in commodity prices since 1980--a major cause of the Third World economic crises--to perceived conflicts of interest between developed and developing countries. Maizels continues his study by discussing the elements of a new approach to an effective commodity policy for the future. He includes coverage of such major problems as the impact of commodity instability on the global economy, market structure, as well as synthetics and diversification. This study will be of interest to academics and students of development economics and international trade as well as to policymakers in developing countries.
