5. CONCLUSIONS This paper introduces an operational hedging vision for logistics uncertainty management in prefabrication construction, aiming to improve the efficiency and effectiveness of decisions throughout the key stages such as prefabrication manufacturing, prefabrication logistics, and on-site assembly. Several key uncertainties are discussed detailed and a demonstrative case from Hong Kong Housing Authority (HKHA) is presented so that practical industrial is able to use the strategies proposed in this paper, for example, time hedging, space hedging, and L+S hedging to ensure the efficiency of integration of decisions (strategic level) and their executions (operational level).
