摘要：Centralized business process execution in the Service Oriented Architecture (SOA) suffers from lack of scalability. Decentralization of business processes is introduced as an alternative approach to address this shortcoming. However, decentralization methods do not consider adaptability of created fragments with runtime environment. The Adaptable and Decentralized Workflow Execution Framework (ADWEF) introduces frequent-path and proportional-fragment adaptability aspects along with two architectures Type-1 and Type-2 and two decentralization methods HPD and HIPD. The ADWEF has been tested for several boundary-condition and one complex business processes; nonetheless, the behavior of prominent activities of business processes has not been studied yet. This paper introduces If-process, While-process and Flow-process as three basic business processes to study the behavior of their central activities from frequent-path adaptability point of view in terms of response-time and throughput running on architecture Type-1. Evaluations of the basic processes show that considering the frequent-path adaptability provides a range of improvements in response-time and throughput with variable-request-rate/constant-message-size and constant-request-rate/variable-message-size configurations.
