Integrating Communication And Engineering Skills In An Industrial Engineering Curriculum Based On Outcome Assessment Results, Leslie A. Potter, John K. Jackman, K. Jo Min, Matt Search Jan 2008

Integrating Communication And Engineering Skills In An Industrial Engineering Curriculum Based On Outcome Assessment Results, Leslie A. Potter, John K. Jackman, K. Jo Min, Matt Search

Industrial and Manufacturing Systems Engineering Conference Proceedings and Posters

To bridge the gap between technical and communication skills of industrial engineering students at Iowa State University, faculty have focused assessment-driven continuous improvement in the curriculum on the integration of communication and engineering skills. Written, verbal, and non-verbal communication skills are addressed through the core communication process (Analysis, Formulation, Creation, Delivery, and Assessment): the focus of a new engineering communications course. This paper describes the creation of this course, including the impetus for inception, course content, structure, and outcome-based learning activities. Student growth and survey results are examined. Long term impact expectations and assessment plans are described.


Working On An Assignment With People You'll Never Meet! Case Study On Learning Operations Management In International Teams, Peter D. Ball, Hilary J. Grierson, Kyung J. Min, John K. Jackman, Patrick Patterson Jan 2007

Working On An Assignment With People You'll Never Meet! Case Study On Learning Operations Management In International Teams, Peter D. Ball, Hilary J. Grierson, Kyung J. Min, John K. Jackman, Patrick Patterson

Industrial and Manufacturing Systems Engineering Publications

This paper examines the results of an international team-based operations management assignment that runs between two universities. The work shows the benefits of giving students a taste of real-life operations management problems both from a technical point of view as well as the challenges faced when working to short timescales, with unfamiliar team players and across time zones. The work has generated valuable understanding of the approach required to set up such inter-institution assignments. It has enabled a process model to be developed to allow others to extract the key stages required for setting up and running them.


Market-Based Electric Power Generation Planning With Emission Control, Shantha Daniel, K. Jo Min Jan 2006

Market-Based Electric Power Generation Planning With Emission Control, Shantha Daniel, K. Jo Min

Industrial and Manufacturing Systems Engineering Conference Proceedings and Posters

Recently, there has been an increasing emphasis on environmental concerns in the electric power industry, especially air pollution. Under this circumstance, we formulate a generation planning model that considers not only the conventional production costs, but also the costs related to air pollution. In particular, we will focus on sulfur dioxide emission which is heavily regulated by Environmental Protection Agency via emission permits. For this particular type of pollutant, we present a generation planning model consisting of an annual strategic model and a weekly tactical model. An illustrative numerical example is provided.


Selection Of Products And Prices In Manufacturing And Remanufacturing Environment, Sasidhar Malladi, K. Jo Min Jan 2005

Selection Of Products And Prices In Manufacturing And Remanufacturing Environment, Sasidhar Malladi, K. Jo Min

Industrial and Manufacturing Systems Engineering Conference Proceedings and Posters

In this paper, we consider a manufacturer who produces both new and remanufactured products facing a group of heterogeneous customers who self-select their optimal choices of products. Under such circumstances, we formulate a mathematical programming model that determines the products, prices, and acquisition prices for used products. Based on this model, we will discuss conditions under which remanufacturing can be encouraged.


Coordinating Forward And Reverse Flows Of Products For A Manufacturer-Retailer Supply Chain Model, Jie Li, K. Jo Min Jan 2005

Coordinating Forward And Reverse Flows Of Products For A Manufacturer-Retailer Supply Chain Model, Jie Li, K. Jo Min

Industrial and Manufacturing Systems Engineering Conference Proceedings and Posters

In this paper, we formulate and analyze a manufacturer-retailer supply chain model with product remanufacturing. This model takes into account both forward flow of the new product as well as reverse flow of the used product. Specifically, we assume that the manufacturer can control the wholesale price of the new product as well the transfer price of the used product from the retailer while the retailer can control the retail price of the new product and the collecting price of the used product. Under this assumption, we compare and contrast the coordinated scenario vs. the uncoordinated scenario. Managerial insights and ...


The Use Of Sacrificial Support Structures In A Rapid Machining Process, Wutthigrai Boonsuk, Matthew C. Frank Jan 2005

The Use Of Sacrificial Support Structures In A Rapid Machining Process, Wutthigrai Boonsuk, Matthew C. Frank

Industrial and Manufacturing Systems Engineering Conference Proceedings and Posters

Rapid prototyping techniques for CNC machining have been developed in an effort to produce functional prototypes in appropriate materials. One of the major challenges is to develop an automatic fixturing system for the part during the milling process. The current proposed method, sacrificial support fixturing, is similar to the support structures used in existing rapid processes, such as Stereolithography. During the machining process, the sacrificial supports emerge incrementally and, at the end of the process, are the only entities connecting the part to the stock material. In this paper, we propose methodologies for the design of sacrificial support structures for ...


Detecting Inconsistency In Functional Software Requirements, Gboyega Sanni, John K. Jackman Jan 2005

Detecting Inconsistency In Functional Software Requirements, Gboyega Sanni, John K. Jackman

Industrial and Manufacturing Systems Engineering Conference Proceedings and Posters

Success in software development depends on the availability of complete, consistent, and unambiguous functional software requirements. Inconsistencies in software requirements can propagate problems throughout the development cycle. We introduce the concept of a quantitative measure for detecting inconsistencies, namely, Potential Structural Inconsistency (PSI). This measure is derived from a structural model for a given set of requirements. We show how this measure can be determined using a case study with known inconsistencies.


Visibility From A Slice File For Rapid Cnc Machining, Matthew C. Frank, Richard A. Wysk, Sanjay B. Joshi Jan 2004

Visibility From A Slice File For Rapid Cnc Machining, Matthew C. Frank, Richard A. Wysk, Sanjay B. Joshi

Industrial and Manufacturing Systems Engineering Conference Proceedings and Posters

A methodology for using CNC machining as a rapid prototyping process is being developed. The method involves cutting complex parts using layer-based machining operations from a plurality of orientations about one axis of rotation. A critical step is to determine the number of and location of those orientations. This paper presents an approach to mapping the visibility of a model about an axis of rotation using a set of model slices taken orthogonal to the axis of rotation.


Data Mining For Production Scheduling, Sigurdur Olafsson Jan 2003

Data Mining For Production Scheduling, Sigurdur Olafsson

Industrial and Manufacturing Systems Engineering Conference Proceedings and Posters

Data mining is a fast growing field and many industrial engineering applications generate large amounts of data to which data mining techniques can be applied. In this paper we develop a data mining framework for production scheduling. This involves preprocessing of historic schedules into an appropriate data file, discovery of key scheduling concepts, and representation of the data mining results in a way that enables its use for job scheduling.


Allocation And Inventory Policies For Reels In Printed Circuit Board Assemblies, Abhishek Bandyopadhyay, Sachin Sulakhe, Sasidhar Malladi, Viveck Rao, Krishna Lakshminarasimhan, K. Jo Min Jan 2003

Allocation And Inventory Policies For Reels In Printed Circuit Board Assemblies, Abhishek Bandyopadhyay, Sachin Sulakhe, Sasidhar Malladi, Viveck Rao, Krishna Lakshminarasimhan, K. Jo Min

Industrial and Manufacturing Systems Engineering Conference Proceedings and Posters

In Printed Circuit Board (PCB) assemblies, various types of reels loaded with different components are extensively utilized. We examine the inventory and allocation policies across assembly lines when the number and size of the reels substantially affect the assembly efficiency (e.g., when the number of available slots in a chip shooter is relatively limited). Critical features of the policies are illustrated via numerical examples.
