Mission Statement

Our History

The NKD-Group is dedicated to the design, manufacture and distribution of analytical software to support quantitative decision makers.  We focus primarily on providing support to the academic teaching community. As financial modeling becomes more quantitatively demanding, The NKD-Group  has produced WinORS that excels in user-friendliness and educational user support.  Our goal is to make it straightforward for you, the application engineer, to use the WinORS product to investigate, apply, and interpret solutions to complex decision models in finance, financial engineering, and operations research.

The history of our commitment to software development dates back to the early 1980s under the DOS operating system.  Today we embrace  agile development principles in our consulting and software development .  The NKD-Group now specializes in developing business models in finance that integrate multivariate statistics, machine learning algorithms, artificial neural networks, data mining, and more to “big data.”




Nina Kajiji is an adjunct associate professor in the Computer Science and Statistics Department at the University of Rhode Island.  She has been conferred the title of Accredited Professional Statistician™ from the American Statistical Association. Her principal research interests are in the fields of applied optimization, volatility modeling, and artificial intelligence. Application fields include: socially responsible investing, neuroscience-based modeling for the development of smart cities, neuroeconomics-based analysis of intra-day municipal bond yield curves, and obtaining complex educational assessment elasticity metrics. Recently, her research interests have expanded to include “big data” analytics featuring both visualization and high-performance computing to assist in complex data mining. Dr. Kajiji’s academic research has been published in several operational research journals, finance journals, and most recently in Neuroscience. 

When not actively working, her personal interests center on container gardening and volunteering with non-profit organizations. She is the co-chair of the European Working Group on Operational Research for Development. For her volunteer work, Nina has been awarded The President’s Volunteer Service Award (Gold Level) from the President’s Council on Service and Civic Participation.  Nina was also honored with the 2013-14 Woman of the Year Award from National Association of Professional Women.
