Abstract
A lean-agile model of homebuilders' production systems is proposed in this research. Value stream mapping is utilized to clarify the proposed lean-agile model, in which pull and Kanban are used to ensure smooth production upstream of the de-coupling point, while fluctuating market demands in terms of variety of homes and variability of volumes are managed by the agile process downstream of the de-coupling point. The decoupling point is used to provide components to downstream agile process and shield upstream smooth production from market fluctuations. A simulation model is developed to evaluate and validate the effectiveness of the proposed lean-agile model. Simulation experiments show that the lean-agile model prevents the accumulation of high inventory levels and thus provides better customization opportunities for clients compared to even-flow-construction. It also provides a more stable process with shorter cycle times compared to sales-driven production. The proposed lean-agile model offers new possibilities for homebuilders to manage the balance between meeting fluctuating market demands and stabilizing the production system.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
