| Summary: | This paper is concerned with the dynamic evolution analysis and quantitative
measurement of primary factors that cause service inconsistency in service-oriented
distributed simulation applications (SODSA). Traditional methods are mostly qualitative
and empirical, and they do not consider the dynamic disturbances among factors in service’s evolution
behaviors such as producing, publishing, calling, and maintenance. Moreover,
SODSA are rapidly evolving in terms of large-scale, reusable, compositional, pervasive, and flexible features,
which presents difficulties in the usage of traditional analysis methods. To resolve these problems, a novel dynamic
evolution model extended hierarchical service-finite state automata (EHS-FSA) is constructed based on finite state
automata (FSA), which formally depict overall changing processes of service consistency states. And also the service
consistency evolution algorithms (SCEAs) based on EHS-FSA are developed to quantitatively assess
these impact factors. Experimental results show that the bad reusability (17.93% on average) is
the biggest influential factor, the noncomposition of atomic services (13.12%) is
the second biggest one, and the service version’s confusion (1.2%) is
the smallest one. Compared with previous qualitative analysis, SCEAs present good effectiveness
and feasibility. This research can guide the engineers of service consistency technologies toward obtaining a higher level of consistency in SODSA. |
