Globalization and increased virtual communication have posed many challenges to high-tech companies; hence, such companies are sparing efforts to detect the best technologies in this field to solve new and emerging challenges addressing traffic load, communication system security, and infrastructure optimization. Telecommunications companies deal with a highly dynamic and uncertain environment, where their relevant technologies are changing and developing at an increasing speed. Regarding such an environment in telecommunications companies, the present study aimed to present an efficient model for formulating technology strategies for these companies. The proposed model is a hybrid method of attractiveness-capability matrix and, multi-criteria decision-making approaches in an uncertain and dynamic environment. The model provides the attractiveness-capability evaluation factors and criteria regarding the requirements of dynamic and uncertain environments in these companies. This approach provides a more accurate picture of the rapidly changing technologies in formulating technology strategy. The model also used the fuzzy TOPSIS to control the uncertainty aroused by widespread emerging technologies in such organizations. The proposed model is implemented concerning the requirements of the Mobile Communications Company of Iran (MCI), and its results are discussed in detail.

“…18 Liesen et al 44 provided the technical approach and emphasized energy savings, implementation of energy efficiency measures in Portsmouth Naval Shipyard, and Jeong et al 45 described the power grid and the simulation of applying flywheel energy storage system on the power grid at the shipyard for shore power to ships and offshore facilities to save fuel consumption and reduce air emissions. In addition, the development of smart shipyards using data envelopment analysis has been shown by Woo et al 46 and the implementation of Industry 4.0 at shipyards using fuzzy AHP-TOPSIS hybrid method has been explained by Cil et al 47 The utilization of different types of renewable energy in shipyards has been investigated in various studies. Hadži c et al 48 identified the feasibility of investments in renewable energy systems for shipyards and the use of a photovoltaic power plant for a shipyard, and the potential of wave power parks for shipyards in Portugal was explored by Miglietta 49 and Neumann et al, 50 respectively.…”

Shipping is looking to progressively develop into a zero-emissions industry, in agreement with pledges made under the Initial IMO Strategy on reduction of greenhouse gas emissions from ships, and its vision to phasing out greenhouse gas emissions as soon as possible during this century. International regulations currently focus on the design and operational phases of the industry, which carries the largest life-cycle climate impact of a ship. As the level of emissions from the operational phase is reduced, the inclusion of emissions from shipyards during construction, maintenance, and disposal becomes increasingly important. The main objective of this study is to improve energy efficiency and reduce air emissions in the shipbuilding industry through the development of an energy-management framework. A systematic literature review was used to define criteria for clean and green shipyards and to develop a novel, holistic, systematic, and transdisciplinary framework for energy management. The energy-management framework is aimed at creating a decision-support mechanism for complex situations, using a multiple criteria decision-making approach. The energy-management framework was applied to case studies of a Bangladeshi and an Italian shipyard. The potential implementation of the framework in yards of different sizes, types and geographical location demonstrates that it has the potential to improve energy management and thereby energy efficiency while increasing productivity and profitability in shipyards.

Purpose: In the last few decades, there has been an increasing growth in research into the use of positioning technologies in open environments. Most of the technologies developed for outdoor environments are used successfully, however, they cannot be considered as fully successful indoors. In this context, various technologies based on Radio Frequency, Infrared, Ultrasound, Magnetic, Optical, and computer vision are proposed to improve positioning indoors. In addition to their individual use, it is also seen in hybrid applications. In particular, Radio Frequency based technologies have potential use in shipyard environments. For this purpose, technologies such as Bluetooth, Ultra broadband, Wireless Sensor Network, Wireless Local Area Network, Radio Frequency Recognition and Near Field Communication are seen as suitable technology options for shipyards. The indoor positioning system is a technology that has the potential to significantly improve work efficiency and safety in the shipyard area. It is difficult to achieve a successful digital transformation of the complex shipyard environment without identifying an Indoor positioning technology for the shipyard. In this study, it is aimed to design a positioning technology that will be most appropriate for the shipyard. Methodology: This paper analyses the challenges for the selection of Indoor positioning system for shipyards in evaluating Indoor-positioning technologies. The methodology followed in this study is a comprehensive comparative analysis of existing IPS technologies on how to digitize shipyards. This article provides an advanced assessment of indoor positioning technologies and their use in the challenging shipyard site. In this context, it provides an evaluation framework for different positioning measures such as accuracy, coverage, scalability, cost, privacy and usability of technologies that can be used within the scope of IPS. Results: The work carried out here on indoor positioning systems and components makes a significant contribution to the shipyard industry. Because it has a great impact on the suitability of technologies, especially in relation to the shipyard environment. Both the evaluation model and solution method, and the Bluetooth-based positioning technology, which stands out at the end of the evaluation, are important contributions of the study. Conclusion: To determine which indoor positioning systems are more suitable for the shipyard environment, both a detailed analysis of the shipyard environment and an evaluation were made to select the most suitable technology. The comparison was made based on observations of the shipyard site and the available literature on the field. This article makes important contributions to future shipyards' application of positioning technologies.
