Analysis Of A New Vehicle Scheduling And Location Problem, Ebru K. Bish, Thin Yin Leong, Chun-Lun Li, Jonathan W. C. Ng, David Simchi-Levi

We consider a container terminal discharging containers from a ship and locating them in the terminal yard. Each container has a number of potential locations in the yard where it can be stored. Containers are moved from the ship to the yard using a fleet of vehicles, each of which can carry one container at a time. The problem is to assign each container to a yard location and dispatch vehicles to the containers so as to minimize the time it takes to download all the containers from the ship. We show that the problem is NP-hard and develop a ...


Effect Of Tactile Feedback On Performance, Darren Paul Wilson Jul 2001

Effect Of Tactile Feedback On Performance, Darren Paul Wilson

Theses - Daytona Beach

Humans interact with their environment by obtaining information from various modalities of sensing. These various modalities of sensing combine to facilitate manipulation and interaction with objects and the environment. The way humans interact with computers mirrors this environmental interaction with the absence of feedback from the tactile channel. The majority of computer operation is completed visually because currently, the primary feedback humans receive from computers is through the eyes. This strong dependence on the visual modality can cause visual fatigue and fixation on displays, resulting in errors and a decrease in performance. Distributing tasks and information across sensory modalities could ...


A Process Theory Of Competency Rallying In Engineering Projects, Bernhard R. Katzy, Kevin Crowston Jan 2001

A Process Theory Of Competency Rallying In Engineering Projects, Bernhard R. Katzy, Kevin Crowston

School of Information Studies - Faculty Scholarship

Firms face an environment changing at an increasingly rapid pace. Market opportunities in particular can arise and disappear in a short time. Unfortunately, the speed with which organizations can adapt their strategies and competencies to meet these opportunities remains limited. We argue that firms can address these individual limitations by cooperating with others for access to market opportunities and needed competencies. In this paper, we present a process theory of how a network of firms can reliably engineering and deliver products in the face of rapid market changes. In this theory, the success of the network is predicated on 1 ...


Senior Design Projects To Aid The Disabled, Janis P. Terpenny, Robert Gao, John Ritter, Donald Fisher, Sundar Krishnamurty Jan 2001

Senior Design Projects To Aid The Disabled, Janis P. Terpenny, Robert Gao, John Ritter, Donald Fisher, Sundar Krishnamurty

Janis P. Terpenny

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 ...


Generation Planning For Electric Power Utilities Under Market Uncertainties: A Real Options Approach , Chung-Hsiao Wang Jan 2001

Generation Planning For Electric Power Utilities Under Market Uncertainties: A Real Options Approach , Chung-Hsiao Wang

Retrospective Theses and Dissertations

The generation business in the U.S. is currently undergoing a transition from a regulated monopoly toward an uncertain, competitive market. Under the competitive market, the price of electric power as well as the corresponding revenue may be much less certain than before. These market uncertainties have increased the significance of two critical factors in generation planning. These factors are financial risks and managerial flexibilities.;In order to quantitatively and objectively address these two factors in generation planning, in this dissertation, we design and analyze a series of mathematical models based on the real options approach for generation planning. Hence ...


Retention Of Female Faculty Members, Susan L. Murray, Mariesa Crow, Suzanna M. Rose Jan 2001

Retention Of Female Faculty Members, Susan L. Murray, Mariesa Crow, Suzanna M. Rose

Engineering Management and Systems Engineering Faculty Research & Creative Works

The recruitment and the retention of female undergraduate and graduate students into engineering courses is discussed. A similar challenge lies in recruiting female faculty member from the limited pool of candidates in several fields at most universities. It is found that about half the females who were hired did not stay at the university. It is suggested that programs should be introduced to encourage mentoring and career development as such improvements would benefit all faculty members both female and male.
