Lean Energy Analysis: Identifying, Discovering And Tracking Energy Savings Potential, J. Kelly Kissock, John Seryak
Lean Energy Analysis: Identifying, Discovering And Tracking Energy Savings Potential, J. Kelly Kissock, John Seryak
J. Kelly Kissock
Energy in manufacturing facilities is used for direct production of goods, space conditioning, and general facility support such as lighting. This paper presents a methodology, called lean energy analysis, LEA, for graphically and statistically analyzing plant energy use in terms of these major end uses.
The LEA methodology uses as few as 60 easily obtainable data points. Multivariable change-point models of electricity and natural gas use as functions of outdoor air temperature and production data are developed. The statistical models are used to subdivide plant energy use into facility, space-conditioning and production-related components.
These breakdowns suggest the savings potential from …

Improving Compressed Air Energy Efficiency In Automotive Plants: Practical Examples And Implementation, Nasr Alkadi, J. Kelly Kissock
J. Kelly Kissock
The automotive industry is the largest industry in the United States in terms of the dollar value of production [1]. U.S. automakers face tremendous pressure from foreign competitors, which have an increasing manufacturing presence in this country. The Big Three North American Original Equipment Manufacturers (OEMs)-General Motors, Ford, and Chrysler-are reacting to declining sales figures and economic strain by working more efficiently and seeking out opportunities to reduce production costs without negatively affecting the production volume or the quality of the product. Successful, cost-effective investment and implementation of the energy efficiency technologies and practices meet the challenge of maintaining the …

Optimally locating new bank branches is a strategic decision in banking industry in order to stay competitive. The importance of this issue is primarily due to the fact that locating branches in appropriate sites is one of the main factors in absorbing and satisfying bank customers. This results in a core benefit for banks, particularly in a vibrant competition. In addition, without a set of well-chosen selection criteria and their prominence, the goal of locating suitable sites for bank branches would not be efficiently achieved. In this research, six most widely used criteria for bank branch location consideration are obtained …

With increasing usage of cellular phones, providing optimum communication service systems becomes a strategic decision to increase subscriber satisfaction. In order to respond to this growing demand it is essential to have a proper design of mobile networks by optimally locating facilities such as Base Transceiver Stations (BTS), switches, etc. In this study, a kind of honeybee-inspired algorithm called Artificial Bee Colony (ABC) algorithm is utilized to solve the problem of assigning cells to switches in the Personal Communication Services (PCS) networks. The model is mathematically developed as a binary non-linear problem with the objective of minimizing cost, which includes …
Data And Analytics For Neighborhood Development: Smart Shrinkage Decision Modeling In Baltimore, Maryland, Michael P. Johnson Jr., Justin Hollander, Eliza D. Whiteman
Data And Analytics For Neighborhood Development: Smart Shrinkage Decision Modeling In Baltimore, Maryland, Michael P. Johnson Jr., Justin Hollander, Eliza D. Whiteman
Michael P. Johnson
Many older cities in the United States confront the problem of long-term decline in population and economic activity resulting in blighted conditions that make conventional revitalization initiatives unlikely to succeed. Smart shrinkage, a planning approach that emphasizes alternative land uses while preserving quality of life, offers a way for cities to remain desirable places to live and work. However, there is little research on empirical methods to support planning decisions consistent with smart shrinkage. We present results from two studies with planners from the City of Baltimore that provide novel insights regarding ways in which planners can perform vacant property …

An Integrated Gray-Fuzzy Cause And Effect Approach To Determine The Most Significant Categories Of Project Risks, Amin Vafadarnikjoo, Mohammadsadegh Mobin, Christian Salmon, Nikbakhsh Javadian
Mohammadsadegh Mobin
Identifying critical risks in projects has become a core step in project risk management process; however, the nature of this step can be complex and unstructured, suggesting a benefit in research towards prioritizing project risks on the basis of a cogent method. This paper presents a Gray Decision Making Trial and Evaluation Laboratory (GDEMATEL) method for prioritizing sources of project risk within a multi-criteria decision making (MCDM) framework. The framework categorizes sources of risk via the Project Management Institutes’ (PMI) Risk Breakdown Structure (RBS). For this study, project expert judgments and preferences are the source of knowledge about project risk. …

The development of commercial maintenance and overhaul manuals for aerospace engines is requisite for certification by the Federal Aviation Administration (FAA). Robust content management systems are used for authoring, publishing, and maintaining these manuals which must meet general industry standards as well as unique company requirements. Therefore, system selection is complex, requiring review of numerous criteria of both quantitative and qualitative nature and is highly dependent on expert judgment which includes uncertainty. In this paper, a major aerospace company was used as a case study for an integrated Fuzzy-Grey Multi-Criteria Decision Making (MCDM) methodology for the selection of a technical …
