Dual sourcing strategies supplement inflexible, low-cost country sourcing with quick response manufacturing. Due to short product life cycles, combined with uncertain demand, dual sourcing strategies are very common in several industries, in particular in the sporting goods or fashion industries.
Even though scholars have given some attention to the analysis of dual sourcing strategies, the importance of the decision-maker's risk preferences has not been covered yet.
In this paper we analyse dual sourcing strategies using an extended single-product newsvendor model with two order points. Different risk preferences will be modelled using an exponential utility function. Within realistic parameter ranges, the optimal order quantities can only be numerically computed. The findings of this paper show that dual sourcing strategies are always preferable to an exclusive offshore approach, as long as the onshore ordering costs are smaller than the selling price of the considered product. The more risk-averse the decision-maker, the smaller the offshore order quantity will be.
