Enhancing Planning and Control for Sustainable Custom and Project-Based Furniture Manufacturing

Abstract

This study investigates production planning and control (PPC) challenges in the Thai furniture industry, particularly in custom and project-based manufacturing. A mixed-methods approach was adopted, combining structured interviews, on-site observations, and the analysis of historical production data to identify inefficiencies in scheduling, task coordination, and resource utilization. The factory implemented integrated PPC strategies such as standardized task planning, workforce optimization, and refined scheduling. As a result, it achieved a 23.58% reduction in delivery delays, a 14% improvement in labor utilization, and a 77.78% increase in the production rate. These outcomes highlight the effectiveness of agile coordination and structured planning in enhancing operational efficiency and supporting more sustainable manufacturing operations in high-variability, make-to-order environments.
