IMGT 8541 - Business Statistics
Statistics is one of the most important analytical tools business people use to solve everyday business problems. Many areas of business are becoming increasingly dependent on data. Learn how to get information from data and interpret statistical results, and you will be able to make informed decisions. This course is designed so that all major topics in introductory applied statistics can be covered in a single semester. Areas covered include data analysis and acquisition, descriptive and numerical methods, statistical inference, regression analysis and statistical process control. Following American Statistical Association guidelines on making statistics more effective in schools of business, the course focuses on fostering statistical thinking, not just teach methods. Attention is given to the analysis of business data and interpretation of the results, with less emphasis on calculations. Because of the important role software packages play in the computation and presentation of statistical results, the course shows how to perform statistical analysis with
Microsoft Excel, a modern spreadsheet.

MBAG 8540 / IMGT 8540 - QuantitatvAnlysis for Business
Making good business decisions is rarely an easy task. The problems faced by decision makers in today’s competitive, fast-paced business environment are often extremely complex and cannot be solved by intuition and subjective judgment alone. This course is about the use of quantitative methods for making better management decisions. It introduces key mathematical models from the fields of statistics, decision analysis, and management science, describes the purpose of a particular model, explains how to formulate and solve the model, and discusses how managers can interpret the use of the solutions to improve their decision making. The real-world application and managerial orientation of the course is designed to motivate students apply analytical approaches and to help them decide which quantitative tools to use in support of specific decision making situations. Topics covered include cost/revenue models and breakeven analysis, probability and probability distributions, decision analysis, forecasting, regression analysis, linear programming, distribution and network models, project scheduling: PERT/CPM, and waiting line models.

MBAG 8648 - Supply Chain Management
Supply chain management is unique and, to some degree, represents a paradox because it is concerned with one of the oldest and also the most newly discovered activities of business. Supply chain system activities – communication, inventory management, warehousing, transportation, and facility location – have been performed since the start of commercial activity. It is difficult to visualize any product that could reach a customer without logistical support. Yet it is only over the last few years that firms have started focusing on logistics and supply chain management as a source of competitive advantage. There is a realization that no company can do any better than its supply chain. This becomes even more important given that product life cycles are shrinking and competition is intense. Supply chain management today represents a great challenge as well as a tremendous opportunity for most firms. In this course we will present and explain concepts, insights, practical tools and decision support systems important for the effective management of the supply chain. Our goal is to understand how supply chain decisions impact the performance of the firm as well as the entire supply chain. The key will be to understand the link between supply chain structures and logistical capabilities in a firm or supply chain.
