(University of Sri Jayewardenepura, Sri Lanka, 2015) Thilakarathna, R.H.; Dharmawardana, M.N.; Rupasinghe, Thashika
Present day supply chains are inherently complex and involve multiple companies working simultaneously within a single function and rivalry is such that it’s a competition not between companies but between supply chains. This ever growing complexity and increased involvement of multiple stakeholders in the supply chain pointed out the need for a universal framework for measuring performance and benchmarking, thus resulting in the Supply Chain Operations Reference Model (SCOR). Globally significance of SCOR for benchmarking, performance measuring and business process re-engineering had been recognized long time back. In previous literature there are many instances where SCOR model had been useful in facing challenges such as constantly decreasing product life cycle and pressure to reduce time to market. In defining the scope of the study basically two dimensions of SCOR was considered: processes and performance attributes adapted from SCOR.A thorough systematic review of existing literature specifically focusing on the application of SCOR model for the apparel industry is being conducted. This study is based on the theoretical gap in the application of SCOR model in relation to apparel industry. Application aspect of SCOR model for improved performance of the apparel supply chain will be presented along further recommendations for local apparel industry for improved benchmarking and competitiveness. This study could be used as a guidance to determine the applicability of SCOR model to other industries as well considering the characteristics of the specific industry.

(University of Sri Jayewardenepura, Sri Lanka, 2015) Heiyantuduwa, M.; Wannisingha, W.M.N.N.; Rupasinghe, Thashika
This topic is of strategic importance where Sri Lanka is moving into a manufacturing economy. In getting there it is vital to find the applicability of using experts in logistics that is called the Third Party Logistics (3PL). 3PLs can be generally defined as outsourcing a firm’s logistics functions to one or more specialist firms which are known as 3PL providers. Over the past few decades, the consumer goods industry has experienced a shift in supply chain strategy from the push approach directed by manufacturers and suppliers to pull approach driven by retailers. Also, there is an increasing emphasis on services, reduced inventory levels and cost of logistics. Because of this increasingly demanding environment in managing consumer goods companies, they are progressively seeking assistance from 3PLs, 4PLs, and LLPs. Outsourcing the logistics functions lets the user focus on their core competencies, while experts take care of the logistics functions, giving the benefits of increased flexibility, reduced costs and improved services. Consequently, identifying potential enhancements in strategic use of 3PLs by the FMCG companies is increasingly being a focus point in current research. Having the objectives of providing a collective picture of current state of knowledge in this context and setting up a path for future research, this study is based on a comprehensive, systematic review of literature published in relation to the strategic use of 3PLs in FMCG industry. The scrutiny identifies several knowledge gaps where strategic use of 3PLs in the industry could be optimized, and develops propositions for future research.

(International Conference on Industrial Engineering and Operations Management, 2020) Warnakulasuriya, M.M.; Niwunhella, D.H.H.; Nanayakkara, L.D.J.F.; Wickramarachchi, Ruwan
When cities are growing in both size and complexity, the freight distribution and management make a significant challenge for transportation management. Freight transportation execution is one of the main sectors that is looked into when planning. The concept of city logistics explicitly tries to optimize the urban transport network and many optimization approaches have been introduced to optimize the vehicle routing methods considering several objectives. Since recent times, there is drawing attention for two-echelon freight consolidation modelling efforts with the emerging of megacities. This paper reviews the available literature under the city logistics modelling, and two-echelon freight consolidation for identifying the perspectives adhered. The study was conducted through a systematic review of literature using multiple studies published under the area of city logistic modeling and two-echelon-distribution modelling in thorough key word base search of city logistic modelling efforts, and performance parameters used for freight analysis within city networks from the findings. The review framework takes into account the diversity and complexity found in city logistics practices. It was evident that there is a lack of modelling efforts in two-echelon vehicle routing for city logistic combining with optimization models for dealing with multiple objective and modeling uncertainty.

(IEEE, 2020) Rajapaksha, R. M. I. U.; Perera, P. S. H.; Nandasena, P. K. D. M.; Gunarathna, P. S. T. K.; Gihan Kanishka, P. P. D.; Ranaweera, A. L. A. K.; Kalingamudali, S. R. D.
There is a growing demand for research in various aspects of smart homes. Automated security systems are an integral part of smart homes. Liquid Petroleum Gas (LPG) is one of the popular fuels used in domestic cooking. Therefore, there is a very high demand for LPG fire security systems. In this study, an automated LPG fire security system for domestic gas leakages has been designed and a prototype model is constructed. The designed system automatically takes preventive measures in case of gas leakage. It includes a newly designed automatically disconnecting regulator from the cylinder which shuts OFF gas supply from commercially available gas cylinders, a control circuit for switching OFF the power supply of nearby area of gas leakage and transceiver unit for sending SMS to the corresponding people. It has been designed to operate automatically when LPG concentration reaches to 200 PPM, a value well below the LPG gas inflammable concentration. LPG concentration is sensed by the MQ-5 gas sensor and fed into the microcontroller. The commercially available gas regulator is modified by attaching a spring and solenoid valve. The spring is compressed when the regulator is ON. Once an LPG leakage of appropriate PPM is detected, a pulse is sent to the solenoid valve such that the attached spring gets rest by removing the regulator from the cylinder. At the same time, a warning message will automatically send to the corresponding users and security personnel through a GSM module attached to the circuit. The circuit is embedded with a rechargeable battery to work even in power outage. Additional gas sensors are installed in electrical switches located near to the gas cylinder and kept in connection with the microcontroller through the Bluetooth module to cutoff electrical power to prevent any spark.
A Model for On-Premises ERP System and Cloud ERP Integration
(International Conference on Industrial Engineering and Operations Management, 2020) Niranga, Mahikala; Wickramarachchi, Ruwan
Market demand changes have led to the emergence of cloud ERP solutions that have become the growing trend nowadays as that they bring new processing capabilities without making significant changes in the existing system. But it alone does not provide businesses with all necessary and best functionalities as different businesses have different requirements. So, integrating multiple best-of-breed applications with cloud to build or fortify a near-custom ERP will automate processes and increase revenue for the business. A survey done by AMR research with 639 companies on integration requirements of SaaS customers shows that 70% of the companies expect to integrate their on-premises legacy applications to the SaaS solution. Also, states that application integration strategy will play the key role in post-modern ERP market. Though integration has been around for over a decade and there are many integration approaches between the two systems, they result in a brittle environment and a progressively more complex architecture as new integrations are added over time. This study analyses whether technological integration, business integration and socio-organizational integration affect the successful integration and aims to develop a model based on the findings for successful integration.

(International Conference on Industrial Engineering and Operations Management, 2020) Gamini, Lakshika; Vidanagamachchi, Kasuni; Wickramarachchi, Ruwan
Warehousing plays an important role in the logistics sector in order to facilitate economic and business benefits for both parties including customer and the service provider. 3PL (third-party logistics) service providers are specialized in providing end-to-end logistics solutions including warehousing, transportation and distribution to their multi-stakeholders in various sectors (Apparel, FMCG). Lean knowledge transferring process from 3PLs to their apparel based multi-stakeholders is a kind of challenging process for both parties due to several factors. The way of transferring and receiving knowledge is directly affected by the success of any business. In this research, a framework is developed on the perspective of 3PLs by examining the factors that affect effective knowledge transferring on lean practices for their clients. Based on these, the model which consists of relevant factors named extent of lean practices, capabilities of the source and the recipient and the relationship between them are providing a clear roadmap to the service provider and their stakeholders. The proposed model will help the 3PL service provider to identify critical success factors for sharing the knowledge of lean practices effectively. Also, it facilitates the successful collaboration with the multi-stakeholders and finally it helps to improve the overall warehouse operational performance.

(International Conference on Industrial Engineering and Operations Management, 2020) Chandrasekara, Sachini; Wickramarachchi, Ruwan
To survive in the market and acquire a competitive edge, industries need to invest in advanced technology. However, most companies fail due to poor integration of technology in their supply chain. The concept of Procurement 4.0 has emerged to optimize supply chain performance developing new value propositions and meeting new business needs. It is the integration of Industry 4.0 concepts in procurement. Although Industry 4.0 concepts have been studied in different industrial contexts, a limited number of researches have been conducted on the use of emerging technologies such as Internet of Things (IoT), Robotic Process Automation (RPA), Big data and Cognitive analytics, Artificial Intelligence (AI) and Cloud technologies, etc. in relation procurement while more existing researchers have focused web-based applications which facilitates real-time communication across supply chains. Therefore, the applicability of industry 4.0 technologies in procurement should be investigated. In this research, a literature survey involving systematic identification and review of 45 articles published in different sources between 2000 and 2019 was carried out to identify different emerging technologies that can be used across the procurement process. Further, the results include the applications of these technologies in the different areas of procurement that supports procurement optimization.
