An Ahp Model for Matching Leagile Strategies for the Off-Site Manufacture in Australia

Australian housing supply has not been responsive commensurately to the growing demand. The residential sector challenges this issue by actively developing and effectively using new materials, processes, and practices to strengthen their competitive advantage against other construction sectors. Three main factors affecting the housing supply and demand are house completion time, cost of finished house, and customer preferences. The best current solution could be introducing the lean and agile concepts to manage the off-site manufacture (OSM) house building supply chain. In this paper, four strategies are introduced to balance the trade-offs between the housing supply and demand. This study presents an example on matching the strategies with the imbalance factors in the Australian house building using Analytical Hierarchy Process (AHP). The AHP model was developed using Expert Choice software package. The results from the AHP model show the benefits of each strategy with respect to each factor tested.
