The M/G/K queueing system is one of the oldest models for multiserver systems and has been the topic of performance papers for almost half a century. However, even now, only coarse approximations exist for its mean waiting time. All the closed-form (nonnumerical) approximations in the literature...

It is well known that scheduling jobs according to the Shortest-Remaining-Processing-Time (SRPT) policy is optimal for minimizing mean response time in a single-server system with online arrivals. Unfortunately, SRPT scheduling requires users to reveal their job size (service requirement), which...

Marketing scholars question the ability of the 4Ps to explain higher order phenomena in modern marketing. Scholars contend that marketing's historical framework, based in product centric economic theory, constrains the 4Ps ability to form a foundation for a general theory of marketing. The focus...

The purpose of this research is to develop a comprehensive, IS assessment framework using existing IS assessment theory as a base and incorporating suggestions from other disciplines. To validate the framework and to begin the investigation of current IS assessment practice, a survey instrument...
