AB  - One important challenge of production systems in both manufacturing and construction is the management of the harmful impacts of variability. While both industries have commonly used buffer-based production strategies to deal with the variability issue, construction is characterized for using intuitive, non-general and wasteful buffering strategies. For overcoming these limitations, this paper describes a conceptual approximation for an integrated buffer (Bf) design and management methodology using Work-In-Process (WIP) in repetitive building projects. The Bf design component uses the Multiobjective-Analytic-Model (MAM) and Simulation-Optimization (SO) modeling, while the Bf management component uses the Rational-Commitment-Model (RCM), an operational decision support tool based on statistical analysis. Each individual component has been previously tested and validated in different case projects. This integrated methodology provides a comprehensive approach to deal with variability using WIP Bf, which explicitly considers: (i) a general production framework which covers the production levels from top to bottom; (ii) a general modeling framework which is suitable to any repetitive building project; and (iii) a sound theoretical framework for describing different production scenarios in repetitive building projects. The main characteristics, advantages, perspectives and limitations of the integrated methodology are addressed in the paper.
