Abstract:
This paper applies Bayesian network tecbnique to
model and inference tbe uncertain relationsbips among cost
factors and benefit factors in E-services. A cost-benefit
factor-relation modelproposed in our previous study is considered
as domain knowledgeand tbe data collectedtbrougb a survey is as
evidence to conduct inference. Tbrough calculating conditional
probability distribution among factors and conducting inference,
this paper identifies tbat certain cost factors are significantly
more important tban others to certain benefit factors. In
particular, this study found tbat 'increased investment in
maintaining E-services' would significantly contribute to
'enbancing perceived company image' and 'gaining competitive
advantages', and 'increased investment in staff training' would
significant contribute to 'realizing business strategies'. These
results bave the potential to improve the strategic planning of
companies by determining more effective investment areas and
adopting more suitable development activities wbere &services
are concerned.
