Item Location Selection of Battery Swap Station using Fuzzy MCDM Method: A Case Study in Indonesia(2023) Maghfiroh, Meilinda Fitriani Nur; Kavirathna, Chathumi AyanthiThe rise of Electric Vehicles (EVs), supported by battery swap systems, brings various advantages, including reduced waiting times, lower upfront costs, and alleviating range anxiety. Battery Swap Stations (BSS) enhance green transportation by providing convenient options for EV users, especially in regions with limited fast-charging infrastructure. Many EVs, especially two-wheelers, need battery recharging after reaching their driving range. BSS availability can eliminate charging inconveniences for busy EV drivers. However, selecting BSS locations is often challenging due to budget constraints. This study aims to understand the criteria for selecting BSS locations in Indonesia. Potential location alternatives were identified using a fuzzy multi-criteria decision-making approach and input from government officials and industry experts. Factors like driving range, EV capacity, and budget availability were considered in determining the order of BSS establishment. The study found that technological and social aspects were the top criteria, suggesting that BSS development should prioritize established locations like mini markets and petrol stations.Item Transshipment Hubs in the Bay of Bengal Region(Centre for Social and Economic Progress, 2023) Kavirathna, Chathumi AyanthiDespite numerous examples to illustrate that dominating the maritime sector is a significant contributor to regional economic growth, the Bay of Bengal region, with its strong geographical advantages, did not explore its full potential in the maritime sector. This region lies strategically halfway along the East-West trade lane, and connects India, a major economy, to the rest of the world. However, the maritime logistics facilities, including seaports, in this region focus on intra region competition rather than exploring a win-win solution through regional cooperation to develop synergetic power to outperform competitors outside the region. Besides the major ports located in Sri Lanka, India, and Bangladesh, ports in Singapore and Malaysia too, play a vital role in serving the Bay of Bengal region, creating overlapping market coverage. Owing to geographical characteristics, hub and spoke networks dominate in the Bay of Bengal region, allowing major ports such as Colombo and Singapore to be promoted as transshipment hubs. Despite the deviation distance and infrastructure limitations, Indian ports attract some transshipment cargo from Indian feeder ports. However, high network connectivity, together with a strong cargo base, is essential to sustain a transshipment hub in a competitive market. The intense competition among ports in this region discourages the concentration of maritime networks and transshipment cargo at a single port, thereby decreasing competitiveness of the region. While focusing on the transshipment hubs in the Bay of Bengal region, this policy brief addresses the connectivity and cooperation deficit in the maritime sector, and the associated untapped potential that hinders regional development. Best-case scenarios for regional development are presented and analysed. Policy recommendations are provided as actionable steps for realising goals, while also addressing issues concerning stakeholders, and resource constraints.Item Feasibility of establishing an integrated railway-based containerised cargo transport network between the Port of Colombo and free trade zones in Sri Lanka(Sri Lanka Society of Transport and Logistics (SLSTL), Moratuwa, Sri Lanka., 2023) Rathnayake, P. G. B. P. S.; Kavirathna, Chathumi AyanthiA large percentage of Sri Lanka's exports and imports are generated by the manufacturing sector and originates from facilities dispersed throughout Export Processing Zones (EPZs) around the country. An efficient hinterland transport network is required between the Port of Colombo and these EPZs. However, road trucks are used as the dominant transport mode for moving containerised cargo to/from Colombo Port. This study proposes a dry port-based containerised import/export cargo transportation method using a railway network to connect the Port of Colombo and the EPZs under several alternative network configurations. This study conducts a questionnaire survey with 40 experts to identify issues with the current road-based container transport network and ascertain the benefits of proposed railway-based networks in Sri Lanka. A majority of respondents highlight the benefits of the proposed network from multiple perspectives along with several drawbacks with the current road-based network. Initially, the feasibility of two alternative dry port locations in Orugodawatta and Kerawalapitiya are analysed. A mathematical model is developed to analyse the feasibility of the proposed alternative networks. Finally, the optimum dry port location is selected as Aluthwaththa using a simulation-based Greenfield analysis approach. Results highlight the advantages of proposed networks under several scenarios. The study demonstrates a systematic approach to decision-making by optimising the local cargo handling process, where, Sri Lankan inland logistic operations will become more efficient, with total transport costs, environmental pollution, and transportation time decreasing significantly.Item Impact of Northern Sea Route on China's grain imports with EU countries(Eastern Asia Society for Transportation Studies, 2023) Ding, Wenyi; Shibasaki, Ryuichi; Kavirathna, Chathumi AyanthiThe Northern Sea Route (NSR) has been navigated successfully with the melting polar ice and developing technology, which will impact China's bulk trade with the European Union (EU) countries. This research mainly investigates the effect of using NSR for grain transport with a minimum comprehensive cost, including shipping costs and environemental effects. Integer programming has been applied to optimize the simulation system with 24 routes and six types of vessels (five conventional vessels and one ice-class vessel) in the with-NSR and without-NSR situations. The result shows that the cost will be reduced by 20% with-NSR scenario, and an additional 7% reduction can be found with the increase in the ice-class vessel fleet. Due to the current demand, panamax-sized vessels are the most preferable. This article also provides an optimal and feasible framework for vessel scheduling in with-NSR and without-NSR situations.Item Feasibility of the Northern Sea route with the effect of emission control measures(Elsevier, 2023) Kavirathna, Chathumi Ayanthi; Shibasaki, Ryuichi; Ding, Wenyi; Otsuka, NatsuhikoDespite shortening voyages between Asia and Europe by the Northern Sea Route (NSR) over the Suez Canal route (SCR), increased NSR’s traffic intensifies vessel-based emissions to the Arctic Sea. This study investigates NSR’s feasibility with a combination of operational and regulatory emissions control (EC) measures against the SCR and NSR’s status quo without EC measures to derive sustainable policy without harming the NSR’s economic feasibility. A mixed-integer nonlinear optimization model decides optimum speeds and heavy fuel oil (HFO)-banned areas for minimizing cost and emissions via NSR. Some scenarios indicate fewer emissions and costs from NSR with EC measures than NSR’s status quo and SCR when emissions taxes are enforced on both routes. EC measures affect NSR’s feasibility depending on ice conditions (ice-free, medium ice, and heavy ice scenarios) and slow steaming potential. A trade-off between economic and environmental objectives encourages combining operational and regulatory EC measures to support NSR’s feasibility.
