Purpose

This paper aims to propose a novel blockchain crowdfunding projects evaluation approach using extended techniques for order preferences by similarity to ideal solution (TOPSIS) under fuzzy environment.

Design/methodology/approach

By analyzing the characteristics and operation process of blockchain crowdfunding model, this paper formulates the evaluation index system from three dimensions of human resources, capital and publicity. In addition, the entropy method is used to calculate the weight of each indicator to avoid subjective judgments; different alternatives are evaluated using the grey correlation analysis (GRA) and TOPSIS-integrated method which considers the distance and similarity between alternatives simultaneously.

Findings

Originality/value

Blockchain crowdfunding has become a new model for fund-raisers to raise funds from public investors. This paper proposes a novel blockchain crowdfunding projects evaluation approach using extended TOPSIS under fuzzy environment.

使用GRA-TOPSIS评估区块链众筹项目

目的

本文旨在提出一种新的区块链众筹项目评估方法，该方法使用模糊环境下通过与理想解决方案相似性（TOPSIS）的订单偏好扩展技术。

设计/方法/方法

本文通过分析区块链众筹模式的特点和运行过程，从人力资源、资金、宣传三个维度制定了评价指标体系。另外，采用熵值法计算各指标的权重，避免主观判断；使用灰色相关分析 (GRA) 和 TOPSIS 集成方法评估不同的备选方案，该方法同时考虑了备选方案之间的距离和相似性。
