Abstract
Purpose
Many experts suggest that the human being explore marine resources and marine new energy sources to alleviate the shortage of land resources and the ecological degradation. However, island coastal zones are considered to be fragile ecosystems; their geographical location and natural characteristics, their biodiversity and associated ecosystems, and their exposure to diverse land and sea conditions all make them highly vulnerable to environmental changes and human activities. Therefore, it is necessary to achieve the goals of environmental protection and sustainable development on the basis of a comprehensive evaluation and understanding of islands.
Design/methodology/approach
Due to the importance of island groups, this paper conducts evaluation studies on them. Using the Delphi, AHP and TOPSIS methods, this study evaluated quantitatively the comprehensive development level and comprehensive development potential of island groups in terms of resources, natural environment, economy and society. Innovatively using them as two subsystems, the present study combined the coupling coordination model and the obstacle factor calculation method.
Findings
The prospective index of comprehensive development was applied to the Changdao Island Group in Yantai, Shandong Province as an example, and the final evaluation revealed that the comprehensive development prospect of this island group had an upward trend from 2010 to 2017. Future efforts should be made to improve its economic and social conditions and economic development status, apart from promoting its comprehensive development by improving human resources management, increasing the GDP growth rate, and improving fresh water and electricity supply.
Originality/value
This study takes the integrated development level of the island and the integrated development potential of the island as two subsystems, and the innovative application of the coupling coordination degree model is used to calculate the integrated development index of the island to understand the development status of the island area. On the basis of this model, the obstacle factor identification method is designed to identify the main obstacle factors, and on the basis of evaluation and identification, specific measures to ensure the sustainable development of the island area are effectively proposed.

Abstract
Purpose
Owing to the importance of the portfolio problem in modern financial investment fields, the aim of this paper is to rank and choose suitable stocks in stock markets under vague environment.
Design/methodology/approach
Many new principles and methods have been introduced to help the investor to decide which stocks are worth to be chosen. In real word, people prefer to express their attributes by using linguistic terms, so the used data are often imprecise and vague. In this paper, the second method of constrained fuzzy analysis hierarchy process (CFAHP) is used to evaluate the relative weights of the criteria and rank alternatives by fuzzy technique for order preference by similarity to an ideal solution (FTOPSIS).
Findings
In this paper, empirical result shows that the proposed method is capable of helping investor to allocate asset in portfolio problems under vague environment.
Research limitations/implications
The proposed method gives a new mathematical framework for portfolio selection. Investors can decide the asset allocation by using the combination of CFAHP and FTOPSIS.
Practical implications
Besides the benefit of sorting feature, the proposed method can be used to obtain the asset allocation.
Social implications
The aim of the portfolio selection theory is to rank and decide the asset allocations. But it is still a difficult task in deciding which assets should be selected under uncertain environment. The proposed method in this paper has been proved to be an efficient method to deal with vague information in decision-making programs.
Originality/value
This study analyzes the effectiveness of the combined method of CFAHP and TOPSIS in portfolio problem.

This paper aims to present a review of articles on business negotiation published between 1995 and 2015.
Abstract
Purpose
This paper aims to present a review of articles on business negotiation published between 1995 and 2015.
Design/methodology/approach
This literature review is based on 490 articles on business negotiation.
Findings
When analyzing the conceptual underpinnings of this field, two paradigms emerge as dominant. The most prominent paradigm is a cognitive, psychological approach, typically relying on experiments and statistical testing of findings. The second dominating paradigm is a behavioral one, largely concerned with mathematical modeling and game-theoretical models.
Practical implications
Besides offering a description of the characteristics adhered to the business negotiation field, this paper will also suggest recommendations for further research and specify areas in which the research field needs further conceptual and empirical development.
Originality/value
This literature review serves to be the first representation of the characteristics adhered to the budding research field of business negotiation.

Abstract
Purpose
The purpose of this paper is to provide a structured methodology to permit the optimal selection of the best‐suited computerized maintenance management system (CMMS) software within maintenance information technologies.
Design/methodology/approach
The analysis has been executed adopting a multi‐attribute decision‐making methodology, namely the technique for order preference by similarity to an ideal solution (TOPSIS). For the selection process, 17 criteria under five main heading have been defined. Data obtained from questionnaires and interviews with the company's maintenance managers have been used in fuzzy TOPSIS.
Findings
The application of the proposed approach allows the maintenance practitioners to concentrate on a limited subset of CMMS applications and to compare their actual capabilities in order to select the right one, rather than considering only their purchase cost.
Research limitations/implications
Comparisons with other multi‐attribute decision‐making techniques such as AHP (analytic hierarchy process) and ELECTRE (elimination and choice expressing reality) under fuzzy conditions can be done for further research.
Practical implications
This paper is a very useful source of information both for maintenance managers and stakeholders in making decisions about the selection of CMMS software.
Originality/value
This paper addresses CMMS software evaluation and selection criteria for practitioners and proposes a new multi‐attribute decision‐making methodology, hierarchical fuzzy TOPSIS, for the problem.
