outsourcing to keep up. Currently‚ we outsource only coarse and medium-sized yarn‚ but we believe that it would be more efficient to look at outsourcing all types. There are so many potential suppliers and constraints to consider that we constructed a linear programming model to identify our best option and check our solution’s sensitivity to changes in our situation. We’ve analyzed our potential suppliers for each gauge‚ taking into account their capacity‚ cost of production for each plant‚ and transportation

Economic inequality encompasses two very concerning issues that negatively affect the citizens of the United States as well as those in other countries. The first is income inequality; "This describes the gap in how much individuals earn from the work they do and the investments they make." Secondly‚ there is wealth inequality which "measures the difference in how much money and other assets individuals have accumulated." (Matthews‚ 2014). There are a variety of opinions on how to address these

Analytical Essay: "The Riddle of Inequality" The riddle of inequality‚ as Tillich explains‚ "...Cannot be solved." This inequality is the divider of people‚ of the have’s and have-nots. It seems that this riddle has confused people since the beginning of time and was even discussed in the bible. People always wonder why some have more than others do; they wonder why this happens and how it can change. I believe that this riddle is natural and cannot be changed despite he best efforts of people

Linear Programming Concept Paper There are two types of linear programming: 1. Linear Programming- involves no more than 2 variables‚ linear programming problems can be structured to minimize costs as well as maximize profits. Due to the increasing complexity of business organizations‚ the role of the management executive as a decision maker is becoming more and more difficult. Linear programming is a useful technique to solve such problems. The necessary condition is that the data must be

Linear Least Squares Suppose we are given a set of data points {(xi ‚ fi )}‚ i = 1‚ . . . ‚ n. These could be measurements from an experiment or obtained simply by evaluating a function at some points. You have seen that we can interpolate these points‚ i.e.‚ either find a polynomial of degree ≤ (n − 1) which passes through all n points or we can use a continuous piecewise interpolant of the data which is usually a better approach. How‚ it might be the case that we know that these data points should
