Cone Quasi-Concave Multi-Objective Programming Theory and Dominance Cone Constructions.
Abstract : Some basic theory of cone quasi-concave multi-objective programming is developed. This new class of vector extremal problems with quasi-concave multiple objective employs ideas of nondominated solutions associated with dominance cones. Necessary as well as sufficient conditions for optimal solutions to such problems are provided. A simple example illustrates the concepts involved. In addition, for general applications in economics, it is shown how to establish dominance cones to realize producer priorities, consumer preferences, and other concerns exogenously determined. Keywords: Mathematical programming, Generalized cone concavity; Vector extremal problems; Multi objective programming, nondominated solutions. (jhd)
US Government organizations are creating value for their citizens and businesses by improving their public service delivery through good websites. Our study examined leadership and IT quality, and their effect on positive delivery outcomes in an e-government environment. We first developed a theoretically based model using elements of the model developed for the Malcolm Baldrige National Quality Award (MBNQA) and DeLone and McLean's IS Success model. To test this model, we conducted a field survey at a municipal city government. The results supported our hypothesis that the MBNQA leadership triad (leadership, strategic planning, and customer/market focus) had a positive impact on the IT quality triad (information, system, and service quality). We also found that both leadership and IT quality increased the benefits.
