Using Electronic Faculty Course Portfolios To Showcase Classroom Practices And Student Learning, Paul Savory, Amy M. Goodburn
Using Electronic Faculty Course Portfolios To Showcase Classroom Practices And Student Learning, Paul Savory, Amy M. Goodburn
Department of Industrial and Management Systems Engineering: Faculty Publications
Faculty course portfolios are a valuable medium for documenting and making visible the serious intellectual work of teaching. Developing a faculty course portfolio follows the same process one uses to explore a research question. Faculty members inquire, analyze, and document their teaching practices and the resulting student learning and then make the results accessible for use, review, and assessment by one’s peers. In this article, we introduce four types of electronic course portfolios that sponsor different forms of inquiry into student learning. We highlight the major components of each type, offer advice in developing them, and share examples of each. …

Optimisation Methods In Supply Chain Applications: A Review, Amr Arisha, Waleed Abo Hamad
Conference papers
The competitiveness and dynamic nature of today’s marketplace is due to rapid advances in information technology, short product life cycles and the continuing trend in global outsourcing. Managing the resulting supply chain networks effectively is a complex and challenging task which is imputable to high level of uncertainty in supply-demand, conflict objectives, vagueness of information, numerous decision variables and constraints. With such level of complexity in the environment, supply chain optimisation has a potential to make a significant contribution to resolve the challenges. In this paper, a literature review – based on more than one hundred peer-reviewed articles – of …

Teaming Multi-Level Classes On Industry Projects, Lizabeth Schlemer, Jose Macedo
Teaming Multi-Level Classes On Industry Projects, Lizabeth Schlemer, Jose Macedo
Industrial and Manufacturing Engineering
For the past few years we experimented with teaming students from a sophomore-level class and a senior-level class to work on industry projects. The classes are “work design” and “facilities design.” Projects are selected to require the application of knowledge from both disciplines. In addition, the projects are selected from small local companies. The intent of this paper is to describe the benefits and difficulties associated with this methodology. While specific classes in this experience are typical of an industrial engineering curriculum, the lessons learned and benefits could translate to other disciplines.
Optimization Of Engineering Tolerance Design Using Revised Loss Functions, Jeh-Nan Pan, Jianbiao Pan
Optimization Of Engineering Tolerance Design Using Revised Loss Functions, Jeh-Nan Pan, Jianbiao Pan
Industrial and Manufacturing Engineering
Engineering tolerance design plays an important role in modern manufacturing. Both symmetric and asymmetric tolerances are common in many manufacturing processes. Recently, various revised loss functions have been proposed for overcoming the drawbacks of Taguchi's loss function. In this article, Kapur's economic tolerance design model is modified and the economic specification limits for both symmetric and asymmetric losses are established. Three different loss functions are compared in the optimal symmetric and asymmetric tolerance design: a revised Taguchi quadratic loss function, an inverted normal loss function and a revised inverted normal loss function. The relationships among the three loss functions and …

Our tool is targeted at home and small business owners in the Pioneer Valley. We begin with the development of two prototype tools. The first was created for the Hitchcock Center for the Environment, and is an Excel-based tool that allows users to select various combinations of technologies and instantly see the financial, environmental, and educational impacts of their choice. The second examines only two technologies, solar photovoltaics and combined heat and power, and uses a cost minimization approach. These …
Finding And Optimising The Key Factors For The Multiple-Response Manufacturing Process, Jeh-Nan Pan, Jianbiao Pan, Chun-Yi Lee
Finding And Optimising The Key Factors For The Multiple-Response Manufacturing Process, Jeh-Nan Pan, Jianbiao Pan, Chun-Yi Lee
Industrial and Manufacturing Engineering
With the advent of modern technology, manufacturing processes became so sophisticated that a single quality characteristic cannot reflect the true product quality. Thus, it is essential to perform the key factor analysis for the manufacturing process with multiple-input (factors) and multiple-output (responses). In this paper, an integrated approach of using the desirability function in conjunction with the Mahalanobis-Taguchi-Gram Schmit (MTGS) system is proposed in order to find and optimise the key factors for a multiple-response manufacturing process. The aim of using the MTGS method is to standardise and orthogonalise the multiple responses so that the Mahalanobis distance for each run …

Automated Fixture Design For A Rapid Machining Process, Wutthigrai Boonsuk, Matthew C. Frank
Automated Fixture Design For A Rapid Machining Process, Wutthigrai Boonsuk, Matthew C. Frank
Faculty Research & Creative Activity
Rapid prototyping techniques for CNC machining have been developed in an effort to produce functional prototypes in appropriate materials. One of the major challenges for rapid machining is to develop an automatic fixturing system for securing the part during the machining process. The method proposed in this paper is the use of sacrificial fixturing, similar to the support structures in existing rapid processes like Stereolithography. During the machining process, sacrificial supports emerge incrementally and, at the end of the process, are the only entities connecting the part to the stock material. This paper presents methodologies for the design of sacrificial …
