    A project is commonly acknowledged as a successful project when the aim of the project is achieved positively. A system called Virtual Learning Environment (VLE) was designed among the students and university academic staff to encourage a positive approach in knowledge achievement and support active learning within the university. This study was carried out to analyze the factors influencing the VLE system and explore the relationship between the students and university academic staff on the system. The factors influencing VLE were identified through the literature review and the interviews which were conducted among the university academic staff and the industry experts. A paper-based questionnaire survey was carried out among the students and university academic staff in order to measure the severity of the factors influencing the VLE system. The respondents chosen for this study were the undergraduate students and university academic staff from Vavuniya Campus of the University of Jaffna, who used the above created VLE system. There were 120 responses from the students and 30 responses from the university academic staff. The students and university academic staff were requested to indicate their level of contribution on various factors in the survey questionnaire with a 5-point Likert scale and the Relative Importance Index (RII) was calculated for each factor. The severity of each factor was identified based on its RII value. The factors were ranked based on their severity and Spearman’s rank correlation coefficient was calculated. It was found that there was 26.9% of positive degree of agreement between the students and university academic staff on the factors influencing VLE. This paper also explores some recommendations to improve the usage of VLE system

    Automated, low-cost pedestrian crossing carriage for efficient traffic control and pedestrian safety
    (IEEE International Research Conference on Smart computing & Systems Engineering (SCSE) 2019, Department of Industrial Management, Faculty of Science, University of Kelaniya, Sri Lanka, 2019) Yasaswin, B.A.O.S.; Jinasena, T.M.K.K.
    Disorganized city planning and a huge rise in use of automobiles on the road have caused massive traffic congestion in cities across the world. Pedestrian crossing designed to facilitate movement across the road network, have unfortunately become a hindrance to movements of traffic. Though the smart zebra lines had been introduced, it has not contributed much to reduce the time that holds vehicle lines under the traffic lights. Moreover, the establishment of transfer hubs and underground crossings remain silent in local context because of their cost. Even though there are plenty of pedestrian crossing mechanisms available, they are not secure and not ideal for the disabled, elderly, children, and the sick. Considerable numbers of police officers have to spend their time on traffic controlling duties though it’s inefficient and wastage of human resources. A number of studies have focused on automated vehicles and robots as tools to ease problems of congestion. This paper, it focuses on the design of an automated guided carriage system for pedestrian transportation in an efficient and secure manner

    Process aligned business rule framework for immunization services in Sri Lanka
    (IEEE International Research Conference on Smart computing & Systems Engineering (SCSE) 2019, Department of Industrial Management, Faculty of Science, University of Kelaniya, Sri Lanka, 2019) Dantanarayana, G.; Jayaweera, P.; Walisadeera, A.
    Identification of healthcare (HC) service processes is a key requirement of successful e-Health system engineering. Ensuring compliance of the HC service process with medical knowledge and guidelines integrated from various written documents and expertise knowledge is a fundamental challenge to e-solution development. Current e-Health solutions often rely on technical level communication and there is no systematic methodology to derive these low level requirements from higher level knowledge base and guidelines. Thus, it is necessary to design a systematic approach to fill the gap between higher level service policies and expertise knowledge with lower level service processes. Therefore, the proposed framework could be considered as a bridge, facilitating e-Health solution for developers to systematically realize high level requirements on underlying technologies. Formalizing care pathway is a promising approach to meet this requirement. However, currently the formalizing care pathway is incomplete due to the complexity in HC domain. The methods also used to implement electronic clinical pathways in other countries are difficult to adopt in Sri Lankan context. This study is an initiative contributing to designing a framework of formalizing a clinical pathway with three main consecutive layers for higher level policy driven service process designing

    Factors influencing Enterprise Information Systems adoption of Small and Medium Enterprises (SMEs): A case study on Sri Lankan manufacturing sector
    (IEEE International Research Conference on Smart computing & Systems Engineering (SCSE) 2019, Department of Industrial Management, Faculty of Science, University of Kelaniya, Sri Lanka, 2019) Kaluarachchi, T.R.; Weerabahu, W.M.S.K.; Nanayakkara, L.D.J.F.
    Small and Medium Enterprises (SME) play a vital role in the Sri Lankan economy in terms of national output and employment as well as incubating innovative capabilities. In today’s highly competitive economy, small and mediumsized enterprises lack the resources and technologies to compete with large enterprises, although having a relatively high casualty rate. In order to survive in the competitive market and exploit opportunities, many small and medium-sized enterprises adopt Information Technology (IT) related applications. However, in the current context of IT Application usage, such as Enterprise Information Systems (EIS), the SME sector in Sri Lanka is lagging compared to other countries. Therefore, the need of adopting to EIS / other Information Systems related technologies is becoming a must or an urgent need in the context of establishing a competitive SME sector. Based on empirical evidence and review of literature this study captures significant factors that influence EIS adoption by SME in Sri Lankan context. The objective of this study is to recognize the real need of EIS based applications for the SME sector while identifying and defining the effectiveness of driving and hindering factors which affect the focus of SMEs adoption towards EIS based applications. Since cost based constraints was identified as a major barrier to adopting EIS based solutions, the increase of productivity and sales profitability are stated as main driving forces by the SME owners and industry experts. The results are expected to provide a practical contribution in the area of EIS adoption in the Sri Lankan Small and Medium manufacturing SMEs for better reinforcement strategies for successful implementation

    GPS guided auto-sensing system for motor vehicles
    (IEEE International Research Conference on Smart computing & Systems Engineering (SCSE) 2019, Department of Industrial Management, Faculty of Science, University of Kelaniya, Sri Lanka, 2019) Ranasinghe, D.C.R.; Wanniarachchi, W.K.I.L.; Anuradha, U.A.D.N.
    Driver errors are the most common cause of traffic accidents. Mobile phones, in-car entertainment systems, traffic volume increases, road systems becoming complicated contribute towards such driver errors. This paper introduces developing a GPS guided auto pilot system for vehicles. This system will be a driverless vehicle system. The user has to give the location of the destination to the system and then the system will automatically navigate to the given destination. These systems are currently used in aircraft, submarines and ships but not used in ground vehicles. Use of such systems in the open street is more complex than use of such systems in air or marine systems. The possible route to the destination must be selected by the vehicle after the destination coordinates are given by the user. Then the vehicle navigates through the open streets without colliding with other moving or non-moving objects. GPS sensor takes real time coordinates of the vehicle and decide the direction to be moved with respect to the given destination coordinates and pass control signals to the motor controller. While navigating, the vehicle keeps appropriate safe distance and speed with the vehicles in front of it. If the lane is not clear, the vehicle applies breaks to avoid collisions. Sonar sensors are used to detect the object in the road as they are more convenient in the outdoor applications. With further developments, this system will be able to assist drivers who drive long trips and play a vital role in minimizing road accidents

    A simulation model to analyse Sri Lankan Megacity logistics behaviour: Megapolis logistics of Sri Lanka
    (IEEE International Research Conference on Smart computing & Systems Engineering (SCSE) 2019, Department of Industrial Management, Faculty of Science, University of Kelaniya, Sri Lanka, 2019) Dias, U.G.M.D.; Tharaka, V.K.; Nanayakkara, J.N.
    Colombo, the commercial capital of Sri Lanka is gradually being transformed into a Megacity with increasing urbanization and industrialization and investment in infrastructure development. Having experienced the consequences of unplanned and non-systematic nature of freight transportation in Colombo city, authorities have come up with a megacity development strategic plan, namely, The Western Region Megapolis Master Plan in order to reduce drawbacks associated with inland freight transportation in urban areas. It focuses on a two tier transportation network structure where the freight is consolidated and value added at hub locations via planned road network and transported to the port for shipping. In this scenario, the transportation structure which connects the consolidation hub with the port and different spokes of the network can be considered as the elementary operational unit of the logistics framework. For analysing operational feasibility of this scenario, simulation-based modelling can be utilized in order to predict the future operational performance of the proposed logistics plan. Having identified the elementary operational unit of functionality in the proposed logistics framework, a computerbased simulation model of the elementary unit is developed using Arena software by Rockwell Automation and validated in order to predict the performance of the two-tier transportation network. This quantitative model has the capability to provide strategic decision-making ability by analysing different scenarios, in terms of traffic congestion, road network utilization and the impact of different truck type combinations for optimum utilization of truck fleet
