Professor Zeephongsekul's research interests are broad, encompassing diverse areas such as stochastic processes, information theory, software reliability analysis, capability analysis, sequential analysis and stochastic modelling of communications networks and tourist movements.
Some fundamental research contributions Professor Zeephongsekul has made are to:
- generalised existing software failure models by incorporating practical concepts such as learning, imperfect debugging and generation of new errors;
- pioneered the use of game theory to problems such as software release policies, management of environmental pollution, seller-buyer supply chains and many others;
- pioneered the application of Fuzzy sets into assessment of software debugging process;
- introduced and analysed the notion of point processes with random fuzzy marks with application to reliability problems; and
- utilised nonparametric methodology based on kernels to estimate well known reliability functions.
Since 2001, he has successfully supervised/co-supervised 10 PhD students. Professor Zeephongsekul am currently supervising 2 PhD students
