Component Obsolescence Risk Assessment, Craig Josais, Janis P. Terpenny, Kenneth J. Mclean
Component Obsolescence Risk Assessment, Craig Josais, Janis P. Terpenny, Kenneth J. Mclean
Janis P. Terpenny
Custom low volume products and systems, such as those utilized by military and avionics applications; often make use of commercial high-tech components. In the past decade, technology has advanced very rapidly causing such components to have a shortened life span. Newer and better technologies are being introduced frequently, rendering components obsolete. Yet, custom low volume products and systems such as ships, submarines and aircraft can be in use for decades. Being proactive about obsolescence is critical to maintaining fully capable products and systems and satisfied customers. This paper presents an obsolescence risk measurement tool that is being developed to better …
The Engineering Economics Of Energy Use And Capital Investment, Janis P. Terpenny, Lawrence L. Ambs, John R. Dixon, Julia L. Sullivan, William G. Sullivan

A potential capital investment involving energy use or energy conservation is always in competition with other possible uses of the same available capital. The competition may come from other energy related projects, or from proposals for, say new production equipment. The situation of “Pay Now - Save Later” is common for energy related decision problems. The comparison of competing energy-related projects is often complicated with unequal useful lives and typically includes substantial initial investments and a variety of recurring costs. Methods of comparison that are frequently used include payback period, return on investment (ROI), and net present value. Further, unit …
K-12 And University Collaboration: A Vehicle To Improve Curriculum And Female Enrollment In Engineering And Technology, Janis P. Terpenny, Thomas Gralinski
K-12 And University Collaboration: A Vehicle To Improve Curriculum And Female Enrollment In Engineering And Technology, Janis P. Terpenny, Thomas Gralinski

In 1993, the State of Massachusetts enacted the Educational Reform Act to improve student performance and to increase school accountability. One of the curriculum frameworks of this initiative is titled Science and Technology/Engineering. One of the strands within that framework, Technology/Engineering, outlines standards in seven curriculum areas to be assessed at the high school level on the Massachusetts Comprehensive Assessment System (MCAS). This framework is somewhat controversial but supported by numerous surveys focusing on national needs. The movement of traditional Industrial Arts programs to a Technology/Engineering approach in both delivery and content has created a new set of problems with …
Utilizing The Internet To Improve Student Learning In A First Course In Engineering Economy With Real-World Unsolved Problems In Collaboration With Industry, Janis P. Terpenny, William G. Sullivan, Harpreet Singh, Kimberly Sward
Utilizing The Internet To Improve Student Learning In A First Course In Engineering Economy With Real-World Unsolved Problems In Collaboration With Industry, Janis P. Terpenny, William G. Sullivan, Harpreet Singh, Kimberly Sward

This paper reports on results of an experiment to investigate whether technology and the Internet facilitate student learning of Engineering Economy through real world problems in collaboration with industry. An overview of the organization and administration of the collaborative projects is presented. Learning aids and Internet tools are included in this discussion. Assessment results of student performance and perception are also presented. It was found using a bootstrap sample, at a significance level of 0.05, that the grade point average (GPA) of students working on projects in collaboration with industry administered through a variety of tools over the Internet (Experimental …
Virtual Classroom For Teaching The Economics Of Engineering Design, Janis P. Terpenny, Kimberly Sward
Virtual Classroom For Teaching The Economics Of Engineering Design, Janis P. Terpenny, Kimberly Sward
Janis P. Terpenny
As decision-makers, engineers must be knowledgeable and competent in multiple aspects of design. Engineering is more than a problem solving activity focusing on simply the expected performance of designed artifacts. Consideration must also be given to the economic consequences of design decisions on life-cycle issues. A major challenge to undergraduate engineering education is to increase student competency in the economic elements that are such a critical part of the engineering process. Many believe that success in this endeavor requires new methods and materials that actively engage students in learning, are more closely aligned with engineering decision-making, and include real-world problems …

A new two-semester capstone senior design course sequence in the area of assistive technology has been developed and integrated within the established curriculum of the Department of Mechanical and Industrial Engineering (MIE) at the University of Massachusetts (UMass) Amherst. Entitled “Senior Design Projects to Aid the Disabled,” the capstone sequence includes close collaborations with the Lemelson Assistive Technology Development Center (LATDC) at Hampshire College and Adaptive Design Services (ADS) under the Massachusetts Department of Mental Retardation (DMR). The new design course allows students to work directly with collaborators and disabled clients to solve specific assistive technology design problems. Through these …
Blending Top-Down And Bottom-Up Approaches In Conceptual Design, Janis P. Terpenny, Bartholomew O. Nnaji, Jan Helge Bøhn
Blending Top-Down And Bottom-Up Approaches In Conceptual Design, Janis P. Terpenny, Bartholomew O. Nnaji, Jan Helge Bøhn

In recent years, there has been significant attention given to improved methods and tools for engineering design. While advances for the latter stages of design have been impressive, this has not been the case for the early stages of design. In general, advances have provided for either a top-down or a bottom-up approach to design; ignoring the requirements for both abstraction and detail in a concurrently engineered development process. This paper describes an integrated conceptual modeling framework for a blended methodology. The utility and extensibility of this framework are considered in discussion and by way of examples.
