  With the increasing importance of sustainability, warehouse sharing arises as
a possible way to improve the efficiency of the existing logistics system. This
paper studied the warehouse sharing platform systems (WSPS) and investigated
its supply chain network, including factories, warehouses, and customers. We
proposed an enhanced modelling approach for the warehouse sharing platform
system design problem (WSPSDP) using the multi-allocation hub location routing
problem framework. New elements such as inter-warehouse transportation and
multiple-allocation scheme were added compared to the existing WSPS model. Then
an adaptive large neighbourhood decomposition search heuristic was applied to
solve our problem. Computational experiments were conducted on different-sized
instances for comparison with the WSPS model without inter-warehouse
transportation and the WSPS model with single-allocation scheme. The results
suggested that our proposed WSPSDP model is more cost-efficient than the
existing WSPS models, and it has the potential to promote the utilisation of
existing cheap idle warehouses.
