Inventory management issues Inventory is the lifeblood of the supply chain. It is what flows from node to node. And at each node its critical to figure out that perfect balance of supply and demand or else suffer dire consequences, if you have too little inventory, you risk lost sales and customers from out of stock. If you have too much inventory, you will need more of everything, ore spaces, handling, transportation, money and labor. There are several companies that have inventory problems;

PRINCIPLES AND APPLICATIONS OF OPERATIONS RESEARCH * Jayant Rajgopal Department of Industrial Engineering, University of Pittsburgh, Pittsburgh, Pennsylvania ABSTRACT This chapter will provide an overview of Operations Research (O.R.) from the perspective of an industrial engineer. The focus of the chapter is on the basic philosophy behind O.R. and the so-called “O.R. approach” to solving design and operational problems that industrial engineers commonly encounter. In its most basic form, O.R. may

1 Mathematical Programming The Mathematical Programming Add-in constructs models that can be solved using the Solver Add-in or one of the solution add-ins provided in the collection. When the Math Programming add-in is installed, several new command lines are added to the OR_MM menu. The menu items under the title Math Programming create models of the different types. Selecting an item from this list causes a dialog box to be presented which constructs a mathematical programming model. The models

Optimization in Production Operations Optimal “Lean Operations” in Manufacturing By Carlos W. Moreno © 2005-06 Ultramax Corporation Oct. 5, 2006 Introduction This essay deals with production / manufacturing operations: with their economic impact (or other metrics) while making product with the existing process, usually driven to satisfy: • market demand (delivered: volume, quality) • • economics (incurred: cost savings, resource utilization); and safety (safeguarding equipment, personnel and

involves the use of mathematical modeling to find the best solutions to problems. This can be applied to a variety of workplace challenges, ranging from making decisions during product development to resolving employee conflicts. It is also known as operations research, and involves a more objective, structured approach to problems or solutions. Many industries can be suited to this management philosophy. One important component of the quantitative management approach is an ability to objectively collect

World War II was most certainly a pivotal event in not only America’s history, but the entire world. It demonstrated that if left unchecked, one man with a desire for world domination can come extremely close to his goals and perform inhumane acts of genocide too. Although there were many significant battles and political maneuvering that strengthened Hitler’s power during the course of World War II, the crucial event that led to the toppling of Hitler’s regime was the stopping of Germany’s advance

LINEAR PROGRAMMING II 1 Linear Programming II: Minimization © 2006 Samuel L. Baker Assignment 11 is on page 16. Introduction A minimization problem minimizes the value of the objective function rather than maximizing it. Minimization problems generally involve finding the least-cost way to meet a set of requirements. Classic example -- feeding farm animals. Animals need: 14 units of nutrient A, 12 units of nutrient B, and 18 units of nutrient C. Learning Objective 1: Recognize problems that
