Previous studies in blood supply chain network design often follow a commonly
used approach in protecting the chain against disruptions, considering the
effects of disruptions on the designing phase. However, in many real-world
situations, disruptions cannot be adequately measured in advance. Moreover, using
disruptions in the designing phase through the common two-stage stochastic
programming models impose high costs on the network, since they cannot be updated
based on unpredicted disruptions. This paper proposes an updatable two-phase
approach which deals with disruptions in the operational phase, not in the
strategic design phase. In the first step, called the proactive phase, a nominal
platelet supply chain network is designed under operational uncertainty, using
the whole-blood collection method. In the event of disruptions, the second step,
called the reactive phase, is applied, and the tailored network is updated based
on the realized data, using apheresis as the collection mechanism. The
operational risks are captured using a fuzzy programming approach in the model.
Based on the real data from Fars province of Iran, we compare the performance of
the two-phase approach with the commonly used approaches in the literature,
resulting in more flexible decisions, and consequently, less conservatism degree
rather than the existing approaches.
