QFD-guided design of a Web-Based DSS Prototype for Sustainable Waste Management in Thailand

Prin Boonkanit, Kridchai Suthiluck

Abstract


This study applied the Quality Function Deployment (QFD) method to translate stakeholder opinions and needs into technical features for developing a prototype web-based Decision Support System (DSS). In Thailand, municipal solid waste (MSW) and construction and demolition (C&D) waste are still difficult to manage, because the rapid growth of cities keeps increasing waste volume and straining local systems. The Decision Support System was created mainly to support local government organizations (LGOs) in making decisions that are more transparent and practical for real operation. Accessibility and usability were carefully checked under WCAG 2.1 standards by using the WAVE tool. The test results showed full compliance with accessibility criteria. A satisfaction survey among 25 experts reported an average score of 4.35 (SD = 0.56) and a satisfaction index of 87 % and 0 accessibility errors, showing strong acceptance. The results indicate that user involvement and simple design are important for future system adoption and for promoting Thailand’s Bio-Circular-Green (BCG) economy toward circular and sustainable waste management.
