Imagine that you have been hired as a consultant to assist in streamlining the data processing of an international based organization that sells high-end electronics. The organization has various departments such as payroll, human resources, finance, marketing, sales, and operations. The sales department is the only department where employees are paid a commission in addition to their yearly salary and benefits. All other departments compensate their employees with a yearly salary and benefits only. Commission is paid by multiplying the employee’s commission rate by the total amount of product units sold. You have access to the following data sets: • Employee (EmpNumber, EmpFirstName, EmpLastName, CommissionRate, YrlySalary, DepartmentID, JobID) • Invoice (InvNumber, InvDate, EmpNumber, InvAmount) • InvoiceLine (InvLineNumber, InvNumber, ProductNumber, Quantity) • Product (ProductNumber, ProductDescription, ProductCost) • Department (DepartmentID, DepartmentDescription) • Job...

...MGSC 372 Fall 2014 Assignment 1 Prof. B. Smith Due Oct 4, QUESTION 1 The Pareto distribution, named after the Italian economist Vilfredo Pareto, is a probability distribution that may be used to describe social, scientific, geophysical, actuarial, and many other types of observable phenomena. Pareto originally used this distribution to describe the allocation of wealth among individuals since it seemed to show rather well the way that a larger portion of the wealth of any society is owned by a smaller percentage of the people in that society. He also used it to describe distribution of income.[8] This idea is sometimes expressed more simply as the Pareto principle or the "80-20 rule" which says that 20% of the population controls 80% of the wealth. This distribution is not limited to describing wealth or income, but to many situations in which an equilibrium is found in the distribution of the "small" to the "large". The following examples, among others, are sometimes seen as approximately Pareto-distributed: * The sizes of human settlements (few cities, many hamlets/villages. * File size distribution of Internet traffic which uses the TCP protocol (many smaller files, few larger ones) * Hard disk drive error rates The Pareto distribution function may be given as follows: fxx0,θ= θx0θx-θ-1 , ...

...The Nonsynonymous/Synonymous Substitution Rate Ratio versus the Radical/ Conservative Replacement Rate Ratio in the Evolution of Mammalian Genes Kousuke Hanada,* Shin-Han Shiu, and Wen-Hsiung Li* *Department of Ecology and Evolution, University of Chicago; and Department of Plant Biology, Michigan State University There are 2 ways to infer selection pressures in the evolution of protein-coding genes, the nonsynonymous and synonymous substitution rate ratio (KA/KS) and the radical and conservative amino acid replacement rate ratio (KR/KC). Because the KR/KC ratio depends on the definition of radical and conservative changes in the classification of amino acids, we develop an amino acid classification that maximizes the correlation between KA/KS and KR/KC. An analysis of 3,375 orthologous gene groups among 5 mammalian species shows that our classification gives a significantly higher correlation coefficient between the 2 ratios than those of existing classifications. However, there are many orthologous gene groups with a low KA/KS but a high KR/KC ratio. Examining the functions of these genes, we found an overrepresentation of functional categories related to development. To determine if the overrepresentation is stage specific, we examined the expression patterns of these genes at different developmental stages of the mouse. Interestingly, these genes are highly expressed in the early middle stage of development (blastocyst to amnion). It is commonly thought that developmental genes...

...Vijay V. Vazirani College of Computing Georgia Institute of Technology Copyright c 2001 Approximation Algorithms Springer Berlin Heidelberg NewYork Barcelona Hong Kong London Milan Paris Singapore Tokyo To my parents Preface Although this may seem a paradox, all exact science is dominated by the idea of approximation. Bertrand Russell (1872–1970) Most natural optimization problems, including those arising in important application areas, are NP-hard. Therefore, under the widely believed conjecture that P = NP, their exact solution is prohibitively time consuming. Charting the landscape of approximability of these problems, via polynomial time algorithms, therefore becomes a compelling subject of scientific inquiry in computer science and mathematics. This book presents the theory of approximation algorithms as it stands today. It is reasonable to expect the picture to change with time. The book is divided into three parts. In Part I we cover a combinatorial algorithms for a number of important problems, using a wide variety of algorithm design techniques. The latter may give Part I a non-cohesive appearance. However, this is to be expected – nature is very rich, and we cannot expect a few tricks to help solve the diverse collection of NP-hard problems. Indeed, in this part, we have purposely refrained from tightly categorizing algorithmic techniques so as not to trivialize matters. Instead, we have attempted to capture, as accurately as possible, the individual character...

...Decision Making,” by Kennard T. Wing, Management Accounting Quarterly (Winter 2000), pp. 1-9. This article points out that oversimplifications of fixed and variable costs can result in the standard costing system not being used or, if used, can lead to bad decisions. That is, misclassifications of cost behavior patterns make variance analyses “paper tigers.” For variance reporting to be useful, financial managers need to develop cost models that reflect how costs actually behave. Discussion Questions: 1. Describe the implications for variance analysis of analyzing a semi-variable cost as either a variable or fixed cost. 2. Describe the implications for variance analysis of analyzing a step-fixed cost as either a variable or fixed cost. 3. Describe the implications on operating decisions of analyzing an operation with mixed costs as either a variable or fixed cost. 15-2: “Variance Analysis Refines Overhead Cost Control,” by J. C. Cooper and J. D. Suver, Healthcare Financial Management (February 1992). This article attempts to analyze the full costs of selected medical procedures using examples from a healthcare organization. A key feature of the analysis is how the overhead variances are handled, and in...

I was teaching Production Engineering subjects till 1972. In the year 1972 I have registered my name for the Industrial Engineering examination at National Institution of Industrial Engineering, Bombay. Since then, I have shifted my field for interest to Industrial Engineering subjects and started teaching related subjects. One such subject is OPERATIONS RESEARCH. After teaching these subjects till my retirement in the year 2002, it is my responsibility to help the students with a book on Operations research. The first volume of the book is LINEAR PORGRAMMING MODELS. This was published in the year 2003. Now I am giving this book OPERATIONS RESEARCH, with other chapters to students, with a hope that it will help them to understand...

...data sets that have both a cross-sectional and time dimension. I spend almost an entire lecture talking about the problems inherent in drawing causal inferences in the social sciences. I do this mostly through the agricultural yield, return to education, and crime examples. These examples also contrast experimental and nonexperimental data. Students studying business and finance tend to find the term structure of interest rates example more relevant, although the issue there is testing the implication of a simple theory, as opposed to inferring causality. I have found that spending time talking about these examples, in place of a formal review of probability and statistics, is more successful (and more enjoyable for the students and me). 3 CHAPTER 2 TEACHING NOTES This is the chapter where I expect students to follow most, if not all, of the algebraic derivations. In class I like to derive at least the unbiasedness of the OLS slope coefficient, and usually I derive the variance. At a minimum, I talk about the factors affecting the variance. To simplify the notation, after I emphasize the assumptions in the population model, and assume random sampling, I just condition on the values of the explanatory variables in the sample. Technically, this is justified by random...

...Chapter 1 [pic] Introduction 1.1 Background Of The Report As being one of the biggest hospitals in Bangladesh, Apollo Hospitals Dhaka is at the forefront of medical technology and expertise and provides a complete range of the latest diagnostic, medical and surgical facilities for the care of its patients. The hospital is having all the characteristics of a world-class hospital with wide range of services and specialists, equipment, & technology, ambience and service quality. But the quality of a hospital service is not defined by the appearance of its facility. Rather the service quality depends more on the sincerity of the hospital and its human resources to serve the patients. In Bangladesh, the health care sector is not yet developed. A large number of people go abroad for treatment due to low quality of medical facilities in Bangladesh. And the main target market of Apollo Hospitals Dhaka is the people who want to get world class treatment inside the country with affordable cost. To ensure the proper customer satisfaction, the hospital management has to employ the right people in right place. Prior to this a detailed job Analysis is almost essential. With Job Descriptions and a sophisticated Job Evaluation system, management will be able to recruit and determine pay levels better, determine the types of training the hospital staff should go on and have a basis to appraise them. Job Descriptions furnished by business units are current and accurate...

...C h a p t e r 1 Prewriting GETTING STARTED (OR SOUP-CAN LABELS CAN BE FASCINATING) For many writers, getting started is the hardest part. You may have noticed that when it is time to begin a writing assignment, you suddenly develop an enormous desire to straighten your books, water your plants, or sharpen your pencils for the fifth time. If this situation sounds familiar, you may find it reassuring to know that many professionals undergo these same strange compulsions before they begin writing. Jean Kerr, author of Please Don’t Eat the Daisies, admits that she often finds herself in the kitchen reading soup-can labels—or anything—in order to prolong the moments before taking pen in hand. John C. Calhoun, vice president under Andrew Jackson, insisted he had to plow his fields before he could write, and Joseph Conrad, author of Lord Jim and other novels, is said to have cried on occasion from the sheer dread of sitting down to compose his stories. To spare you as much hand-wringing as possible, this chapter presents some practical suggestions on how to begin writing your short essay. Although all writers must find the methods that work best for them, you may find some of the following ideas helpful. But no matter how you actually begin putting words on paper, it is absolutely essential to maintain two basic ideas concerning your writing task. Before you write a single sentence, you should always remind yourself that 1. You have some valuable ideas to tell your reader,...
