Architecture-centric" is viewed as the main longitude line, basic agent logic is the latitude assembly realization element, which is to build deep organization model about software business process. To achieve this goal, this paper puts forward helix-increased model's polarization concept.About layer-layer's transparent increment requirement and the existing automatic analogy character among layers, here finishes deeply formal position from the perspective of agent's Belief, Decision-making and Ability, then achieves Agent-0's evolution, and realizes agent architecture system's business process.

SUMMARYSelf-adaptive software is a closed-loop system, since it continuously monitors its context (i.e. environment) and/or self (i.e. software entities) in order to adapt itself properly to changes. We believe that representing adaptation goals explicitly and tracing them at run time are helpful in decision-making for adaptation. While goal-driven models are used in requirements engineering, they have not been utilized systematically yet for run-time adaptation. To address this research gap, this article focuses on the deciding process in selfadaptive software, and proposes the Goal-Action-Attribute Model (GAAM). An action selection mechanism, based on cooperative decision-making, is also proposed, which uses GAAM to select the appropriate adaptation action(s). The emphasis is on building a light-weight and scalable run-time model which needs less design and tuning effort comparing with a typical rule-based approach. The GAAM and action selection mechanism are evaluated using a set of experiments on a simulated multi-tier enterprise application, and two sample ordinal and cardinal preference lists. The evaluation is accomplished based on a systematic design of experiment and a detailed statistical analysis with ANOVA in order to investigate several research questions. The findings are promising, considering the obtained results, and other impacts of the approach on engineering self-adaptive software. Although, one case study is not enough to generalize the findings, and the proposed mechanism does not always outperform a typical rule-based approach, less effort, scalability and flexibility of GAAM are remarkable.
