Construction Product Quality Improvement with Applying Production Problems Analysis

Product Quality Improvement Using Multivariate Data Analysis

A data-based methodology for improving product quality is proposed. Referred to as Data-Driven Quality Improvement (DDQI), the proposed method can cope with qualitative as well as quantitative variables, determine the operating conditions that can achieve the desired product quality, optimize operating condition under various constraints, and thus can provide useful information to improve produ...
