Critical Success Factors Of Internet Of Things Applications In Taiwan?€(Tm)S International Commercial Ports, Tan-Shou Shee, Guo-Y Gan, Hsuan-Shih Lee Aug 2018

Critical Success Factors Of Internet Of Things Applications In Taiwan?€(Tm)S International Commercial Ports, Tan-Shou Shee, Guo-Y Gan, Hsuan-Shih Lee

Journal of Marine Science and Technology

Rapid technological developments have led to innovations in international commercial port operations worldwide. Leading ports have effectively applied new technologies to integrate their port resources. These ports have used the new technologies to reduce waste, thereby increasing their global influence and economic value. The Internet of things (IoT) enables vehicles, devices, and other items embedded with sensors and actuators to exchange data across an established network. IoT technology has been extensively applied in commercial ports, including in cruise-assisting transportation systems that simultaneously manage port electricity, water, and energy use. This study suggests that technology development and user trust should receive …

Evaluation Of The Key Development Factors For The Shanghai Cruise Tourism Industry Using An Interval-Valued Fuzzy Number Method, Qian-Feng Wang, Hsuan-Shih Lee, Jian-Yong Shi, Feng-Ming Tsai, Guo-Y Gan

Journal of Marine Science and Technology

Rapid development has occurred in the cruise tourism sector in Asia accompanied by a global cruise market shift to the East. Rapid economic development has led to substantial growth in China’s cruise tourism. Because of this rapid development and new demand for cruise tourism, Shanghai has become the largest cruise port in Asia. Because Shanghai is under pressure from the increasing demand for cruises, analyzing the key factors for developing the cruise tourism industry in the city is necessary. The main purpose of this study was to evaluate the key developmental factors of Shanghai’s cruise tourism industry by using an …

Identifying Techniques For Improving Chinese Guanxi Quality Of Ocean Freight Forwarders In Taiwan, Tsung-Yu Chou Apr 2018

Identifying Techniques For Improving Chinese Guanxi Quality Of Ocean Freight Forwarders In Taiwan, Tsung-Yu Chou

Journal of Marine Science and Technology

In this study, quality function deployment (QFD) and gray relational analysis (GRA) were combined to develop a gray QFD approach to determine the techniques for improving the Chinese guanxi quality (CGQ) of ocean freight forwarders in Taiwan. The first step was to identify the consignors’ needs and technical requirements of improving the CGQ. Then, a relationship matrix was constructed to link technical requirements and consignor’s CGQ needs based on cross-functional expertise. Finally, the grey relational analysis was employed to determine the execution priority of technical requirements. The results revealed that the top five technical requirements to improve the CGQ with …

Super-Efficient Or Super-Inefficient? Insights From A Joint Computation Model For Slacks-Based Measure In Dea: A Note, Der-Long Lin, Wen-Li Chyr, Guo-Ya Gan, Hsuan-Shih Lee Apr 2018

Super-Efficient Or Super-Inefficient? Insights From A Joint Computation Model For Slacks-Based Measure In Dea: A Note, Der-Long Lin, Wen-Li Chyr, Guo-Ya Gan, Hsuan-Shih Lee

Journal of Marine Science and Technology

Chen (2013) extended the exiting SBM approaches and developed a joint model (J-SBM) that can (1) simultaneously compute SBM scores for inefficient DMUs and super-efficiency for efficient DMUs, (2) guarantee the reference points generated by the J-SBM are Pareto-efficient, and (3) the J-SBM scores of a DMU are continuous in the input and output space. In this note, we provide a counter example which shows that the reference point generated by the J-SBM might not be Paretoefficient, and the current study has also revised the model (8) proposed by Chen (2013).

Efficiency Measures For Vrm Models Dealing With Negative Data In Dea, Shiue-Jen Tung, Guo-Ya Gan, Wen-Li Chyr, Hsuan-Shih Lee Apr 2018

Efficiency Measures For Vrm Models Dealing With Negative Data In Dea, Shiue-Jen Tung, Guo-Ya Gan, Wen-Li Chyr, Hsuan-Shih Lee

Journal of Marine Science and Technology

This paper explores the properties of the efficiency measures of the variant of radial measure (VRM) which is capable of dealing with negative data in DEA. We found that the inputoriented efficiency measure for VRM might be negative and the range of the output-oriented efficiency measure for VRM might be limited to [0.5, 1]. To circumvent these two situations, we propose the new efficiency measures which prevent the inputoriented efficiency from becoming negative and the outputoriented efficiency from being limited to [0.5, 1].

Dynamical Study Of A Moored Vessel Using Computer Vision, Andres Figuero, Alvaro Rodriguez, Jose Sande, Enrique Peña, Juan R Rabuñal Apr 2018

Dynamical Study Of A Moored Vessel Using Computer Vision, Andres Figuero, Alvaro Rodriguez, Jose Sande, Enrique Peña, Juan R Rabuñal

Journal of Marine Science and Technology

Wind and wave effects have a major impact on the design of mooring and anchoring systems, whose purpose is to prevent the movement of the cargo and the moored ship while optimizing the operations which have to take place in port. The dynamic behavior of a ship moored in waves has been mathematically described and interactions between ships and environmental loads have been commonly tested for different docks and mooring systems in scale models. However, the behavior of real ships in true mooring conditions has not been properly addressed in scientific literature. This paper proposes a novel computer vision technique …

Efficiency Measurement For International Container Ports Of Taiwan And Surrounding Areas By Fuzzy Data Envelopment Analysis, Yu-Jie Wang, Tzeu-Chen Han Apr 2018

Efficiency Measurement For International Container Ports Of Taiwan And Surrounding Areas By Fuzzy Data Envelopment Analysis, Yu-Jie Wang, Tzeu-Chen Han

Journal of Marine Science and Technology

International container ports are critical hubs for global logistics, and high efficiency is a particularly important requirement for managing these ports. International container ports in Taiwan and surrounding areas have to deal with increasingly larger amounts of cargo in recent years. As a result, it has become more difficult to measure these ports’ efficiency. This study offers a new approach for measuring the efficiency of international ports. Twelve international container ports in Taiwan and surrounding areas were chosen as the samples, and their six inputs (application service process, service personnel ability, service personnel attitude, advisory services, harbor rates and stevedoring …

Optimal Imperfect Preventive Maintenance Logistic Inventory Model With Backorder And Minimal Repair, Yuh-Ling Su, Ming-Feng Yang, Mengru Tu, Yi Lin Feb 2018

Optimal Imperfect Preventive Maintenance Logistic Inventory Model With Backorder And Minimal Repair, Yuh-Ling Su, Ming-Feng Yang, Mengru Tu, Yi Lin

Journal of Marine Science and Technology

This study developed and evaluated an integrated inventory model incorporating production programs and maintenance to model an imperfect process of a deteriorating production system in firm’s activities of inbound logistics and production. Two preventive maintenance activities are performed during each production run period: perfect preventive maintenance and imperfect preventive maintenance. The perfect preventive maintenance’s probability depends on the number of imperfect maintenance operations performed resulting from the last renewal cycle. The occurrence of a failure causes defective products which have a certain number of the ability of rework and not to be rework, and those cannot rework will lead to …

A Zigbee/Rfid Safety System At The Seaport, Sanja Bauk, Diego Garcia Gonzalez, Anke Schmeink

Journal of Marine Science and Technology

The paper examines three potential safety solutions for the protection of port workers, which are based on a junction of Radio Frequency IDentification (RFID), as an automatic identification, data collecting and positioning system from one side, and ZigBee, as a low energy consumption communication technology from another. The considered solutions are placed in the context of the individual needs and capacities of the developing Port of Bar in Montenegro (South East Europe), which has been operating in the transitional environment for the past two decades. The transitional circumstances prevent the port from adopting advanced occupational and environmental safety systems. Therefore …
