After more than 25 years working in a wide variety of computer related areas, I have a broad range of experience:
I have experience using a number of modeling tools, both simulation and queuing theory, such as SES/Workbench and SES/Strategizer (HyPerformix, formerly SES), Simul8 (Simul8 Corporation, formerly Visual Thinking International Ltd), QASE (AST Engineering Services), SPEED (PES) and Best/1 (BMC, formerly BGS ). I have lead several extensive modeling efforts and published the results both as company internal documents and at conferences.
My most recent planning experience has been technology planning; the analysis of the suitability of computer technology to the current and future needs of both the applications and the support organizations.
I have done capacity planning for very large, large and small environments, which included projecting application growth and predicting the required resources to maintain the business objectives for those applications.
I have a large number of publications in both national magazines and conference proceedings. Many of these papers have also been presented at regional, national and international conferences. Although I specialize in performance and capacity modeling topics, I have also written in a variety of other areas.
I have developed applications using a number of techniques and environments, including batch systems, transaction systems (such as IMS and CICS), interactive systems (such as TSO and ISPF), operating systems, and PC systems using Microsoft Windows and Visual Basic.
My experience with hardware includes supporting configuration changes for both large and small MVS environments. I have also been responsible for the operating system changes to implement the new hardware configurations.
I specialize in modeling for performance analysis and capacity planning using both simulation and queuing theory techniques.
