Planning and managing the task allocation process in offshore software development outsourcing environment plays an important role in order to develop the good quality software with in time and budget. In this study we investigate the berries that negatively affect the task allocation process in geographically distributed development environment. A literature review and questionnaire survey approach was adopted in order to investigate the barriers of task allocation process. The investigated barriers were further classified into four core categories i.e. team, coordination, project administration and technology. A total of 14 barriers were identified from the literature and validated with organizational experts by using questionnaire survey. The findings revolved that all the survey respondents are agree with the findings of literature review. We further analyze the investigated barriers based on organizations size, to check the significant difference between the barriers with respect to organization size (small, medium and large). Moreover the categorization of the investigated barriers indicate that the project administration is the most significant category of investigated barriers of task allocation process. The findings of this study may helpful for researcher and practitioners to consider the most significant barriers of task allocation process in the context of offshore software development outsourcing environment.
This research presented a holistic approach in determining the trade-off optimized Proportional-Integral-Derivative (PID) tunings for both servo and regulatory controls of the cascade control loop by using Genetic Algorithm (GA). Performance of GA-based PID tunings was significantly compared with the IMC-based single loop tunings and conventional cascade control tunings. GA-based PID tunings eliminated the complicated mathematic calculations in obtaining the correlation PID tuning values and also reduce the dependency on engineering knowledge, experience, and skills. The performance of transient and steady-state responses was compared through time domain specification, performance index, and process response curve. It is concluded that the GA-based PID tunings for the cascade control loop had produced the best result for both servo and regulatory control objectives, which is eventually determined.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
