Application of fuzzy extended AHP methodology on shipping registry selection: The case of Turkish maritime industry

Selection of the suitable shipping registry alternative for the existing fleet or new building ships is one of the critical decision milestones of the shipping business. The main aim of this paper is to structure a practical decision support mechanism on ensuring multiple criteria analysis of shipping registry selection. Fuzzy AHP methodology, based on Changs extent analysis, is determined to be utilized in order to model the shipping registry selection. After structuring the fundamental hierarchy, the model is performed with a case application on Turkish maritime industry to be able to obtain illustrative results. The shipping registries of Turkiye, Panama, and Malta are determined to evaluate as the potential alternatives for Turkish ship owners. When the literature was examined for the applications of analytical methodologies on maritime business, it was seemed that they were so rare. Therefore, the originality of this study appears on modeling of the critical process under multidisciplinary philosophy in ship management.

Fuzzy axiomatic design-based performance evaluation model for docking facilities in shipbuilding industry: The case of Turkish shipyards

The closest relationships between ship management companies and shipyards begin with the initial design process of new ships and they continue during the life cycle of operating ships. Periodic docking facilities which can be recognized as the biggest logistical issue in the content of ship maintenance program are the critical processes from the viewpoint of ship owners. Hence, this process should be well-planned and organized to satisfy the various expectations such as quality of service, capacity limitations, and geographical advantages, by taking cost and time constraints into account. Hence, the selection problem with respect to several criteria to find the most suitable shipyards is getting more important for ship management companies. This paper investigates a systematic evaluation model on docking facilities of shipyards to provide a decision aid for technical ship managers and to perform this responsibility in an efficient manner. Multiple criteria fuzzy axiomatic design (FAD) approach is used for selection among shipyards since FAD lets us define the design interval of each criterion. The original contributions of the paper are seemed in both enhancing the theoretical frame of FAD in terms of managing group consensus and performing an application to a real case in maritime industry.

The strategic positions and geographical advantages of the Turkish container ports in the world transportation network create an excessive demand which seek urgent development strategies for managing ongoing problems in operational and administrative level. This paper proposes a hybrid approach on ensuring the competitiveness requirements for major Turkish container ports by utilizing fuzzy axiomatic design (FAD) and fuzzy technique for order performance by similarity to ideal solution (TOPSIS) methodologies to manage strategic decision-making with incomplete information. The outcomes of the quantitative models are utilized as data input for SWOT analysis that provide additional contributions for identifying the development strategies on container ports. The proposed strategies on Turkish container ports can be originally recommended as guidelines both for port administrations and new enterprises in Turkish maritime industry.

An integrated fuzzy QFD model proposal on routing of shipping investment decisions in crude oil tanker market

Monitoring the market has crucial roles for executing the shipping investment decisions in maritime transportation industry. The high level of managerial effort requires bringing market tendencies with the up-to-date data over dynamic parameters. This paper extends the Quality Function Deployment (QFD) principles towards shipping investment process via the originally proposed Ship of Quality (SoQ) framework. Furthermore, the Fuzzy Analytic Hierarchy Process (FAHP) and Fuzzy Axiomatic Design (FAD) algorithms are integrated into the SoQ frame in order to involve quantitative outcomes into the shipping investment decisions. The SoQ is performed over a set of periodical data and recent trends of the principal crude oil tanker markets such as Very Large Crude Oil Carriers (VLCCs), Suezmaxes, and Aframaxes in order to ensure the illustrative results. As an effective investment tool, the proposed SoQ model is expected to provide invaluable decision aid for the relevant shipping executives.

Structuring fuzzy integrated multi-stages evaluation model on academic personnel recruitment in MET institutions

Managing the competency and proficiency designation during academic staff recruitment in maritime training is vital to ensure sustainable development of educational activities. This problem seeks for a systematic decision aid mechanism which could be adopted into the official recruitment procedures of academic administrations. Hence, this paper proposes fuzzy integrated multi-stages evaluation model (FIMEM) under multiple criteria in order to manage the academic personnel selection and development processes in Maritime Education and Training (MET) institutions. The diversity of evaluation attributes requires making an assessment via both fuzzy and crisp values. Moreover, performing SWOT analysis over the initial outcomes adds development strategy capability towards the assigned academic personnel. Consequently, this paper has suggested utilization of FIMEM as a recruitment toolkit in MET institutions in order to prevent the probable conflicts and manipulations in evaluation process of candidates for different academic positions.

A multi-methodological approach for shipping registry selection in maritime transportation industry

Selecting the most suitable registry alternative for shipping fleets has become a highly complex strategic activity for ship owners in the maritime transportation industry, and necessitates consideration of both internal and external environmental factors, which can be both qualitative and quantitative. The aim of this paper is to propose an originally structured multi-methodological approach based on the systematic application of the SWOT analysis, the AHP and the TOPSIS methods to support the critical decision process on shipping registry selection under multiple criteria. In the proposed approach, the SWOT analysis is utilized to determine the key assessment factors on the shipping registry decision and to structure the decision hierarchy. While the AHP is used to measure the relative importance of evaluation criteria in this decision hierarchy, the TOPSIS is applied to rank the shipping registry alternatives. As a case study, major open registries are analyzed to select the most suitable of them for the fleet that is operated by a worldwide ship owner. The results show that the proposed multi-methodological approach takes the advantages of the SWOT analysis, the AHP and the TOPSIS to select the most suitable shipping registry. The proposed approach also provides a relatively simple and very well suited decision-making tool for this type of strategic decision making problem.

Computer-based systematic execution model on human resources management in maritime transportation industry: The case of master selection for embarking on board merchant ships

Human resources management (HRM) have been increased its functionality and popularity in the shipping business, due to the expeditiously changes in technology, market strategies, risks and challenges in transportation industry. Despite the requirements of International Convention on Standards of Training, Certification and Watchkeeping for Seafarers (STCW), held by International Maritime Organization (IMO), especially the quality and competency of personnel who are being employed on board ships are primarily issue of shore-based ship management organizations. This paper proposes an extendable and applicable model based on Analytic Network Process to support the personnel selection facilities of crewing departments in ship management companies. The priorities of evaluation factors are outlined for employing the Master, the most significant and key personnel on board merchant ships, as a case application in this study. Consequently, the results are elaborated to construct a scheme on evaluating of job applications for embarking Master on board ships. The model can be achieved to modify for carrying out to evaluate the employment criteria for other ranks on board ships as a further study.

A hybrid design methodology for structuring an Integrated Environmental Management System (IEMS) for shipping business

The International Safety Management (ISM) Code defines a broad framework for the safe management and operation of merchant ships, maintaining high standards of safety and environmental protection. On the other hand, ISO 14001:2004 provides a generic, worldwide environmental management standard that has been utilized by several industries. Both the ISM Code and ISO 14001:2004 have the practical goal of establishing a sustainable Integrated Environmental Management System (IEMS) for shipping businesses. This paper presents a hybrid design methodology that shows how requirements from both standards can be combined into a single execution scheme. Specifically, the Analytic Hierarchy Process (AHP) and Fuzzy Axiomatic Design (FAD) are used to structure an IEMS for ship management companies. This research provides decision aid to maritime executives in order to enhance the environmental performance in the shipping industry.
