A Structural Equation Model of Information Systems Development and Supply Chain Management
This paper employees structural equation modeling to analyze the effects of information system development and supply chain management on manufacturing objective and organizational performance. Survey data of middle managers from Taiwan s computer and electronics industries was used to test the relationships between the constructs in the model. In general, the survey results supported the proposed structural equation model. It is observed that information system development facilitates supply chain management practice and manufacturing objective attainment. In addition, there are significant relationships between supply chain management and manufacturing objective, as well as between manufacturing objective and organizational performance. However, the impacts of information system development and supply chain management on organizational performance were not supported by the data. The study concludes that information system development and supply chain management does not lead to better organizational performance directly. Introducing supply chain management through information system development helps to achieve manufacturing objective, and finally improves organizational performance
A Decision Support System for Improving Doctors' Prescribing Behavior
The study adopts a well-defined game theory with a decision support system (DSS) to embed the critical factors involved in coordination game equilibrium. A data-warehouse-based DSS is used as a coordinating instrument along with the disclosure of quality report cards. Feedback on prescribing, giving information on aggregated data, along with the DSS, could be sufficient to improve prescribing behavior. The aim of this study was to apply a DSS with pre-play communication of the coordination game theory to the improvement of doctors' antibiotic prescribing behavior. We examined whether the DSS improved the prescribing behavior, and assessed how well the participating doctors improved quality of care. We found the group using the system had a greater decrease in antibiotic prescription than the non-DSS group. This study concluded that the DSS with game-theory modeling has made significant contributions for improving the doctors' prescribing behavior. Future research directions and managerial implications are addressed as well
