Implementing ERP (Enterprise Resource Planning) system successfully comes with a set of costly and complex challenges. The purpose of this paper is to offer an effective cloud-based ERP software evaluation framework to gain a better understanding of these complexities and address such challenges by identifying the selection criteria. The PFS (Pythagorean Fuzzy Set) is the new extension of Intuitionistic fuzzy sets, the Simple Additive Weighting (SAW) is an easy-to-use technique to determine the weights of the criteria, and the VIKOR technique is a compromise ranking methodology. In the recommended novel integrated MCDM (Multi-Criteria Decision-Making) methodology, Decision-Makers (DMs) must choose the best one among a set of candidate alternatives that satisfies the evaluation criteria. The GDM (Group Decision Making) is preferred here to deal with hesitancy in the evaluation of alternatives under group preferences. The sensitivity analysis resulted from various scenarios reveals that the proposed method is quite sensitive to criteria weights. The service and support, cost, and functionality are found as the essential evaluation criteria for the Turkish firm. These findings emphasize the significance of a qualified group of DMs for the evaluation process. The case study findings demonstrate that the developed approach is practical and validated for solving software development projects. This study presents a novel integrated methodology based on the PFS, SAW, and VIKOR to measure the performance of software development projects, to deal with the ambiguity and imprecision caused by the subjective judgments of DMs. The research contributes to the literature by delivering a combined decision methodology for the first time and by applying it to evaluate the software development projects.

成功实施 ERP（企业资源规划）系统伴随着一系列代价高昂且复杂的挑战。本文的目的是提供一个有效的基于云的 ERP 软件评估框架，以便更好地了解这些复杂性，并通过确定选择标准来应对这些挑战。PFS（毕达哥拉斯模糊集）是直觉模糊集的新扩展，简单加法加权（SAW）是一种易于使用的确定标准权重的技术，而 VIKOR 技术是一种折衷排序方法。在推荐的新型集成 MCDM（多标准决策）方法中，决策者 (DM) 必须在一组满足评估标准的候选方案中选择最佳方案。GDM（群体决策）在这里被首选用于处理在群体偏好下评估备选方案时的犹豫。各种场景的敏感性分析表明，所提出的方法对标准权重非常敏感。服务和支持、成本和功能被认为是这家土耳其公司的基本评估标准。这些发现强调了合格的 DM 组对评估过程的重要性。案例研究结果表明，所开发的方法对于解决软件开发项目是实用且经过验证的。本研究提出了一种基于 PFS、SAW 和 VIKOR 的新型集成方法来衡量软件开发项目的性能，以处理由 DM 的主观判断引起的模糊性和不精确性。
