(International Research Conference on Smart Computing and Systems Engineering - SCSE 2018, 2018) Senanayake, J.M.D.; Wijayanayake, J.
Traffic is one of the most significant problem in Sri Lanka. Valuable time can be saved if there is a proper way to predict the traffic and recommend the best route considering the time factor and the people’s satisfaction on various transportation methods. Therefore, in this research using crowdsourcing together with data mining techniques, data related to user mobility were collected and studied and based on the observations, an algorithm has been developed to overcome the problem. By using developed techniques, the best transportation method can be predicted. Therefore, people can choose what will be the best time slots & transportation methods when planning journeys. The algorithm correctly predict the best traffic-less traveling method for the studied area of each given day & the given time. Throughout this research it has been proven that to determine the best transportation method in Sri Lankan context, data mining concepts together with crowdsourcing can be applied. Based on a thorough analysis by extending the data set of the collection stage, it was shown that this research can be extended to predict the best transportation method with consideration of existing traffic in all the areas.
An approach to coexistence analysis between agility and ERP implementation
(International Research Conference on Smart Computing and Systems Engineering - SCSE 2018, 2018) Rajakaruna, R.J.P.K.; Wijayanayake, J.
Business organizations tend to re-engineer their business processes by adopting Enterprise Resource Planning (ERP) systems in order to gain a competitive advantage. ERPs offer countless benefits by enabling an enterprise to operate as an integrated, process oriented and real time enterprise. But the issue is re-engineering with ERP ranks among slow-moving, costly and challenging processes of an organization. Many ERP specialists regard agile approaches positively, to mitigate the common ERP implementation challenges. Agile implementation of ERPs is still under research area. This research discusses on the need of agile approaches in ERP implementations and how agility and ERP implementations can coexist. In this case our research question is “Can the common ERP implementation challenges be solved by using agile approaches?” and if so, “How these challenges can be solved?” This study also seeking for uplift the level of awareness on the applicability of agility for ERP implementation projects and these findings can be effectively used by ERP Implementers, Vendors, Consultants, Project Managers and Researchers in their respective projects.
Coordination and control in virtual teams in software industry
(International Research Conference on Smart Computing and Systems Engineering - SCSE 2018, 2018) Koggalahewa, L.; Wijayanayake, J.
The last couple of decades has witnessed a steady, irreversible trend towards globalization. Economic forces have relentlessly turned national markets into global markets while emerging competition and corporations reach across national boundaries. More than a decade ago, seeking lower costs and access to skilled resources, many organizations began to experiment with remotely located manufacturing and service facilities. The ready availability of skilled IT personnel at very competitive prices in developing nations like India, and the rapid infrastructure development in these countries made it a ready industry to make this transition. With this trend, emerged the concept of virtual teams. Virtual teams are work arrangements where team members are geographically dispersed and work interdependently through the use of electronic communication media to achieve common goals. There is a difficulty in developing strategies for various team processes in virtual teams. The objective of this research was to identify the factors influencing working of virtual teams and strategies to facilitate better coordination and control among them in the context of software development. Literature revealed the factors that affect the coordination process of virtual teams in software development. The factors identified include level of authority of team members, leadership style, media synchronicity of the team, distribution of information within the team and experience in working together. Then a conceptual model was developed to analyze the impact of each factor in virtual team coordination. A detailed questionnaire was used to obtain views of industrial experts. The results concluded that the developed model is significant and it explains sixty-six percent of the working of virtual teams. It was shown that, level of authority and media synchronicity are the most significant of the factors. The applicability of the model was verified by conducting interviews with software industry personnel. The study also focused on finding reasons for using virtual teams, pros, cons and problems faced by virtual teams in Sri Lankan context. The findings can be used to better coordinate software projects with the use of virtual teams.

(Institute of Electrical and Electronics Engineers (IEEE), 2024) Perera, K. G. D. K.; Wijayanayake, J.; Prasadika, J.
In today's era, technology has become pervasive worldwide, significantly facilitating access to learning resources. Notably, the emergence of Generative Artificial Intelligence (AI) has garnered rapid attention and interest in a short period with the introduction of ChatGPT. Many individuals have extensively discussed and evaluated this AI-powered language model, from researchers to casual internet users. Importantly, Generative AI applications are increasingly recognized for their potential in educational contexts. In the realm of education, AI has the potential to significantly broaden and improve teaching and learning in higher education. However, while numerous studies have explored the effectiveness of Generative AI applications in programming language learning, an absence of research examining their impact comprehensively exists. Hence, this study aims to identify the factors that affect the successful utilization of Generative AI applications in the context of undergraduate programming language learning, with a particular emphasis on the viewpoints of university students. A systematic literature review was undertaken to obtain the research objectives, adhering to the Prisma 2020 guidelines, which involved selecting and analyzing 47 prior studies. Mainly this study utilized a systematic literature review to comprehend the factors influencing the effective utilization of Generative AI apps by undergraduate students in their programming learning experiences. Furthermore, the study discusses the advantages and challenges university students face when learning programming using generative AI applications.
The Impact of Teleworking on Sri Lankan University Internship Programs: Systematic Review of Literature
(Institute of Electrical and Electronics Engineers (IEEE), 2024) Abeygunawardhana, D.; Wijayanayake, J.; Prasadika, J.
The popularity of the Work from Home paradigm has seen a significant surge in relevance and importance, due to the COVID-19 pandemic and its associated quarantine measures. This shift towards teleworking has influenced the landscape of internships also. While some aspects of teaching and learning have smoothly transitioned into online environments, Others face several challenges. Identifying the specific strategies, skills, and practices required for effective online learning, especially in the context of an online internship course, remains a less defined domain specially in Sri Lanka. The pandemic-induced transition to remote work and education has been a global phenomenon, yet its impact on internships remains relatively unexplored. Moreover, the existing literature on new Information and Communication Technologies (ICT) and teleworking is frequently outdated due to the rapidly changing technological landscape. This systematic literature review tries to identify the impact of this shift towards teleworking on university internship programs in Sri Lanka. Internships are essential for an undergraduate to find future career opportunities. Also, to strengthen their self-confidence and self-satisfaction in the lifelong learning process. When considering the major drawbacks, there's a big gap in communication between interns and their supervisors, harder to establish and maintain work relationships when interns can't be physically present or meet their supervisors face-to-face. There are identified positive sides also. Big companies and smaller ones alike can benefit from virtual internships. They're good for both students and employers because they're flexible, cost-effective, and easy to access. Plus, virtual internships can be especially helpful for differently abled students. This benefits both the employer and the student. Also mentoring is identified as a key factor for the success of virtual internships.
