外掛式區塊鏈程式之開發-以二級品管表單為例

在營建工程全生命週期中，工程品質管理扮演著關鍵角色，確保工程品質達到預期目標，且符合法規和業主要求。然而，傳統管理方法如人工作業和紙本文件紀錄，可能因人為操作失誤、大量繁瑣作業，而導致工作出問題。許多公司已開始使用數位工具來改善這些問題，其中透過使用專案管理資訊系統（PMIS），簡化作業流程可以減少錯誤發生。但是使用專案管理資訊系統，就需要注意資安問題，要防止資料被破壞、修改等問題。區塊鏈技術，特別是其分散式紀錄、加密技術和共識機制，提供了解決這些問題的可能。加上智能合約的自動執行與不可修改性，可以提升專案管理資訊系統的可信度。然而，將區塊鏈技術導入到現有的系統中，需要重新設計系統架構、整合區塊鏈模組，這會耗費大量時間、人力資源和財務成本，並帶來業務中斷和風險增高的問題。因此，本研究嘗試開發一外掛式區塊鏈程式，整合至現有的專案管理資訊系統，避免重新設計系統架構，減少導入區塊鏈技術所需的資源成本。希望透過此次開發，提高將區塊鏈技術導入專案管理資訊系統的可行性，以及加強資料的安全性和完整性，並推進營建工程數位轉型的進程。

In the entire life cycle of construction projects, engineering quality management plays a crucial role in ensuring that the project's quality meets the expected standards and complies with regulations and owner requirements. However, traditional management methods such as manual operations and paper-based record-keeping can lead to human errors and a cumbersome amount of work, resulting in issues during the project. Many companies have begun using digital tools to address these challenges, including the adoption of Project Management Information Systems (PMIS) to streamline processes and reduce the occurrence of errors. However, the use of PMIS requires careful attention to cybersecurity to prevent data tampering or unauthorized modifications. Blockchain technology, with its decentralized record-keeping, encryption techniques, and consensus mechanisms, offers potential solutions to these challenges. The implementation of smart contracts, with their automatic execution and immutability, can enhance the credibility of the PMIS. However, integrating blockchain technology into existing systems necessitates redesigning system architecture and integrating blockchain modules, which can consume significant time, human resources, and financial costs, leading to potential business disruptions and increased risks. As a result, this research attempts to develop a plug-in blockchain program that can seamlessly integrate into the existing PMIS, avoiding the need for complete system redesign and reducing the resource costs associated with blockchain adoption. The aim is to enhance the feasibility of introducing blockchain technology into the PMIS, improve data security and integrity, and advance the digital transformation of construction projects.
