The rapid growth of e-commerce in Sri Lanka has resulted in an increase in the number of e- customers and e-retailers. To sustain this growth, e-commerce players must differentiate their offerings and operations to meet the evolving needs of customers, with customer satisfaction being a crucial factor in achieving a competitive advantage. Delivery logistics plays a critical role in ensuring customer satisfaction. A systematic literature review, following the PRISMA framework, identified the most impactful delivery logistics factors on customer satisfaction as delivery time, cost, and quality. Building upon this, the study utilized the mental accounting theory (MAT) to develop a conceptual framework. The objective of this study was to examine the relationship between delivery logistics factors and customer satisfaction and to explore the moderating effect of geographical variations and product categories on this relationship. Data was collected from a sample of 272 respondents living in rural and urban areas, using a structured questionnaire. The data were analyzed using partial least squares structural equation modelling (PLS-SEM). The findings suggest that delivery logistics factors have a positive impact on customer satisfaction and that the geographical location of customers, and the product category moderate this relationship. Specifically, for econsumers from rural areas, delivery cost was found to be a significant predictor of customer satisfaction. Furthermore, delivery logistics factors positively influenced customer satisfaction for shopping and special goods, but not for convenience goods. Overall, this study emphasizes the importance of delivery logistics in e-commerce, particularly in a developing country like Sri Lanka. It provides valuable insights for e-commerce players to enhance their operations and offerings, meet customers' needs, and improve their competitiveness.

ERP implementation failure can be one of the most expensive errors a business can make. It is critical to understand the success factors behind the effective usage of an ERP system in order to reduce the risk of failure. A large quantity of literature and research are available on factors behind a successful ERP initial implementation, but it lacks studies on post implementation. Moreover, there’s no such work has been done concerning the moderation implication of organizational culture and economic uncertainty over the association between the identified factors and the effective usage of ERP system making it a new addition to literature. Therefore, this research aims to study the success factors behind the effective usage of the ERP system in the post-implementation period and how the above moderators can moderate these factors on the effective usage of ERP system. A survey questionnaire was used to collect data from the users who are using an ERP system in a matured company in Sri Lanka. A preliminary data analysis was done using SPSS software and hypothesis were evaluated using Partial Least Squares Structural Equation Modelling approach as it enables researchers to estimate complex models with many constructs, indicator variables, and structural paths without imposing distributional assumptions on the data. The results of the study suggest that all the independent variables namely top management support, complexity of the ERP used, business IT infrastructure, hidden costs in ERP changes and training on ERP were influencing drivers for the effective usage of ERP system. In addition, concerning the moderator effect of organizational culture, top management support, ERP complexity and IT infrastructure showed a significant impact while the moderator effect of economic uncertainty, top management support, ERP complexity and training showed significant but negative relationship on the effective usage of the ERP system.

This research paper introduces a groundbreaking smart system designed to assist hearing- impaired students in comprehending spoken Tamil, the second language in Sri Lanka. The system addresses the challenges faced by these students by incorporating cutting-edge deep learning techniques, including Convolutional Neural Networks, Hidden Markov Models, and Recurrent Neural Networks, for efficient feature extraction and sequence modeling within an Automatic Speech Recognition framework. Additionally, the paper proposes a novel method for automatically recognizing Tamil Sign Language gestures using advanced hand gesture recognition algorithms and a comprehensive dataset of Tamil Sign Language. The system encompasses four primary classification approaches, enabling the conversion of Tamil Sign Language to Text. Text to Tamil Sign Language, lip reading to Tamil Sign Language, Normal voice to Tamil Sign Language - Sign Language to Normal Voice and physical object identification to both text and Tamil Sign Language. Notably, the system achieves remarkable results, boasting an impressive accuracy rate of 0.99% surpassing existing Automatic Speech Recognition and Text-to-Speech systems. This significant breakthrough holds immense potential in enhancing the learning experience of hearing-impaired students in Tamil-speaking regions. Furthermore, the system's adaptability allows for future expansion to support additional languages, making it highly versatile for diverse educational and communication settings.

Currently, in Sri Lanka, the road (truck) has always been the dominant transport mode for moving import/export containerized cargo to/from Colombo port. According to the past literature, there are a lot of road-based containerized cargo transportation issues in Sri Lanka. This study introduces a dry port-based containerized import/export cargo transportation method using a railway network to connect the port of Colombo and the Board of Investment (BOI) Export Processing Zones (EPZ). A dry port is an inland intermodal terminal, directly connected by a railway line to the Colombo port. The study mainly focuses on two dry port-based networks under several alternative network configurations. The locations of the proposed dry ports are Orugodawatta's current customs clearing yard and cargo inspection center in Kerawalapitiya proposed by the Asian Development Bank (ADB). In this study, mathematical models were developed to analyze and compare the cost, environmental, and time benefits of the proposed networks between major BOI EPZs and Colombo port considering current freight demand. The results highlighted the advantages of the proposed network under several scenarios from economic and environmental and travel time perspectives. Then the study estimates the import/export BOI freight demand for 2050 and analyzes the potential of the proposed railway- based cargo transport system for 2050. These figures can be further reduced by optimizing the dry port location. Therefore, a simulation- based approach was considered to optimize the dry port location by Greenfield analysis method with “Supply Chain Guru” software. Through simulation results, the study shows the new dry-port location compatibility for the proposed system. The findings of the study have demonstrated a systematic approach to decision-making by optimizing the local cargo handling process. By adopting this system, Sri Lankan inland logistic operations will become more efficient and the total transportation costs, environmental pollution, and transportation time will decrease significantly.
