- ItemA mixed integer programming model of the logistics of sulfuric acid in chile(1998) Maturana Valderrama, Sergio; Contesse Becker, LuisThe logistics of sulfuric acid in Chile have become increasingly important as stricter environmental laws are enacted and enforced. Large copper companies are very concerned about this problem since they are both producers and consumers of sulfuric acid. Since storing, shipping and disposing of sulfuric acid is relatively expensive, there is a strong incentive for optimizing its logistics. This paper describes a model developed for the largest copper producer in Chile to analyze, at a strategic level, the problem of the logistics of sulfuric acid in Chile. © 1998 Blackwell Publishing Ltd.
- ItemA Mixed-Integer Programming Model for Gas Purchase and Transportation(2005) Contesse Becker, Luis; Ferrer Ortiz, Juan Carlos; Maturana Valderrama, SergioThe natural gas supply chain involves three main agents: producers, transportation companies, and local distribution companies (LDCs). We present a MIP model that is the basis for a decision support system developed for a Chilean LDC. This model takes into account many of the complexities of the purchasing and transportation contracts to help optimize daily purchase and transportation decisions in the absence of local storage facilities. The model was solved to optimality within a reasonable time. We show how the model handles several contractual issues and give some insights for the case when demand scenarios are used to deal with uncertainty.
