The "Painting Trades" include commercial and industrial painters and drywall finishers, which are normally represented by the same labor union for collective bargaining purposes. They are also members of the same construction trade organization, the Finishing Contractors Association (FCA). Labor is the greatest variable cost of performance for these trades and so, labor productivity is a...
Stud Framing, Drywall, and Tape and Finishing trade-work is a major component of every building project. Labor productivity is the largest single variable affecting of the Framing and Drywall contractors' cost of performance. In spite of these facts, no major study of labor productivity in this major construction trade has previously been done. This study was undertaken to fill this gap in the literature;...
Selecting medical hardware can be a difficult and permanent decision for patients that they are often unprepared for. The authors explore the use of pairwise comparison techniques to better inform medical decision making in an application of choosing between three major cochlear implant manufacturers. This paper appears to be the first study to apply a pairwise comparison decision making approach...
Technology forecasting using data envelopment analysis (TFDEA) captures technological advancement from the evolution of the state-of-the-art (SOA) frontier. Within this process, TFDEA combines rates of changes (RoC) from past technologies that have been superseded by superior technologies. However, it was occasionally observed in previous applications that forecasting based on a single aggregated...
Technology Forecasting using Data Envelopment Analysis (TFDEA) has been employed to a wide range of applications because of its ability to model complex tradeoffs. The very name indicates that it is based on Data Envelopment Analysis (DEA) which has strength that it doesn't require fixed a priori weighting scheme. Instead, it adopts dynamic weighting scheme that each data point can choose their best...
The Toyota Prius was introduced in Japan fifteen years ago and over 60 additional hybrid electric vehicles automobiles and redesigns have been brought to the market around the world since that time. There is major interest in future of the electric cars as using “the alternative fuel” can significantly decrease the environmental and fuel dependency concerns. This work has used data envelopment analysis...
This study presents a formal comparison of TFDEA with regression model to forecast wireless communication technology. In addition to the data set from the former research, up-to-2011 4G network technologies are added and analyzed. The research was designed to set the point of forecasting in 2001 so that technologies between 2001 and 2011 are to be forecasted using data set between 1979 and 2001. The...
This paper describes an Excel add-in program that can run TFDEA (Technology Forecasting using Data Envelopment Anlaysis) within the spreadsheet. It utilizes freely available statistical software R and its packages developed by Statconn. This add-in allows access to both user-friendly tools for data manipulation in spreadsheet available and the power and precision of the results via R.
Tech Mining can help ascertain whats happening in Management of Technology (MOT). Previous analyses of PICMET and IAMOT content helped identify the emergence of hot topics in the field and the leading research centers associated with those. The present profile helps assess research priorities and opportunities in MOT. This can help you position your work; identify leaders on particular topics, perhaps...
U.S. academic research institutions spent public and private funds of 54 billion dollars solely in 2009. This is a significant investment considering recent harsh economic downturn. While there exists public acknowledgement of importance of unremitting investment on research and development, U.S. research institutions still struggle to validate their performance and get reliable support from public...
A set of 49 elementary, middle, and high schools from a single school district are examined using five existing metrics and compared with the data envelopment analysis, DEA, benchmarking tool. The DEA results are then decomposed to examine the impact of scale efficiency and the results are compared to another a study of buildings in Taiwan.
In many business sectors today, focus on quality as a competitive tool is being replaced by a focus on innovation. Research exploring connections between quality management, innovation, and company performance suggests that quality is ‘necessary but insufficient’ in business today. In short, managers need to know how to adapt their quality management practices to achieve innovation performance in...
Technology Forecasting with Data Envelopment Analysis (TFDEA) offers an effective means to determine technological capability over time without the burden of fixed a-priori weighting schemes. However, a commonly used extension of TFDEA can create situations where there are multiple feasible solutions. This can introduce challenges in reproducing results for practitioners. This paper resolves this...
Due to the limitation in the availability of resources (time, money and researchers) for research projects, it is always a policy and decision maker's challenge to decide on appropriate research projects or programs to support as well as how much money should be spent and how the funding should be managed in order to achieve the research goals. Thus, it would be helpful to provide the information...
<para> The question, <emphasis emphasistype="italic">“How to assign projects to project managers?” </emphasis> is considered to be one of the most important questions in project management. Nevertheless, methods to answer this question have not yet been sufficiently addressed in the literature. In practice, even though the question is rather common, practitioners still...
