Lecture Resources

This Lecture Resource provides the derivation for the flow dominance measure. It was developed by Uday Venkatadri. The flow dominance measure is used by facilities designers to decide whether a given from-to matrix (process to process flow matrix) has a few dominant flows or nearly all equal flows.

This lecture resource covers the basics of creating an initial block layout design of a facility. The slide set initially presents From-To, Flow-Between and Relationship charts. It then introduces adjacency and layout scoring and the construction of activity and space relationship diagrams. The CORELAP algorithm is then introduced along with an example for selecting and placing departments. A heuristic procedure for developing a layout is then presented. Finally, a general procedure for graph based layout construction is presented and discussed.

This lecture resource covers basic models and efficient techniques for facility location. The slide set first introduces the problem of facility location along with the broader topic of logistics management. It then presents appropriate distance measures and a classification of planar facility location problems based on these measures. Four types of planar single facility location models are studied in detail. These models consider two different objective functions (minimizing the total travel distance and minimizing the maximum travel distance) and two distance measures (rectilinear distance and Euclidean distance). Lastly, the planar multi-facility location problem with rectilinear distance and the objective of minimizing the total travel distance is studied. Examples and solutions for all five location problems considered in this module are also provided.

This model introduces the vehicle calculation problem in automated material handling systems. The presentation starts by introducing the major factors which affect this problem such as unit load size, flow path network and P/D station location and how they relate to each other. The model then introduces the basic vehicle calculation formula which is based on quantifying the different states the vehicles may be in. Next the model presents and classifies the different calculation methods according to simple versus complex methods, one dimensional versus multi dimensional methods and analytical based versus simulation base methods. Finally the model presents a numerical example and solution.

This lecture resource provides an introduction to Automatic Identification (AutoID). It covers linear bar codes (Universal Product Code (UPC), Interleaved 2 of 5, Code 39, and Code 128), 2D barcodes (PDF417, DataMatrix, Maxicode), and bar code readers. Also included are magnetic stripe cards, smart cards, RFID, contact memory, and voice identification. Sample applications of AutoItechnologies are described.

This module covers flow analysis techniques that are helpful for the efficient design of a facility. The slide set initially provides some of the factors that affect material flow and examines various types of flow patterns. It then presents different procedures for measuring and planning flow. Five general types of layout types are introduced, and advantages and disadvantages of each type are given. A relevant flow dominance measure to determine the most appropriate type of layout for a facility is described. At the end, special attention is given to the group layout, and techniques to construct part families and machine cells are described.

This Lecture Resource explains the basics of RFID, how the system works, and compares RFID to bar codes. It discusses limitations of the technology and the cost. The operational frequencies are given, as well as a description of active and passive tags. The electronic product code is explained. The presentation gives a brief history of RFID and numerous applications. Importantly, it discusses the current controversy (circa July 16, 2005) concerning the technology.

This lecture resource on Warehouse Management Systems (WMS) provides an overview of WMS purpose, features and functions. It begins with a short overview of Supply Chain Execution (SCE) systems and the role of WMS within an entire suite of SCE applications. The presentation then concentrates on the information flows and data that are vital to successful implementation. Finally, costs, justification, important measures and trends are presented.

This lecture covers warehouse design and control at a high level. The author begins with a review of basic warehouse operations, then covers the warehouse design methodology proposed by Yoon & Sharp (1996). A few slides cover warehouse activity profiling, then the final portion presents Rouwenhorst's (2000) strategic, tactical, and operational design and control methodology.

How to configure a fast-pick area in a warehouse. The lecture covers Bartholdi & Hackman's theoretical fluid model, which shows how to determine (1) which items to include in a fast pick area, and (2) in what quantities. The author also presents a similar model for case picking from pallets, including the Law of "None, One, or All."

This lecture covers several topics in configuring storage areas, including the concepts of random, dedicated, and class-based storage. The author gives several related models and shows how to locate I/O points, how to size random and dedicated storage areas, and how to compute optimal lane depth for randomized block stacking lanes.

This lecture covers analytical models for order picking, including constructing picking tours and batching orders. The author covers the pick sequencing algorithm of Bartholdi and Platzmann and the order batching procedure of De Koster. He also includes an addendum of Ratliff and Rosenthal's special case polynomial-time algorithm for constructing picking tours. Slides include many graphics and illustrations!

This lecture resource is provided as an accompaniment to the paper by Eric Johnson and Russell Meller on Split-Case Sorting Systems (M&SOM, 2002). Split-case sorting systems are used by many large retailers (amazon.com, L. L. Bean, Sears, etc.) to efficiently handle high volumes of small orders. The presentation covers the main points of the paper, including a model for the throughput of the system. There is a good deal of material to introduce split-case sorting systems for those not familiar with them. The material is most suitable for graduate students in industrial engineering or logistics (although the general results are appropriate for undergraduate students as well).
