Abstract: In the present scenario, individual firms do not compete as independent entities rather as an integral part of a supply chain. Uncertainty is the major attribute in managing the supply chains. Accordingly, we develop heuristic methods to determine optimal inventory policies of facilities in a supply chain system under fuzzy stochastic environment. The total cost of the inventory system is computed using defuzzification methods. To determine an optimal policy, a numerical technique is presented and the results are analysed with the help of a numerical example.

Keywords: economic order quantities; fuzzy sets; vendors; customers; optimal policies; inventory policies; fuzzy stochastic environments; facilities; independent entities; integral parts; uncertainty; heuristic methods; facility inventories; total costs; defuzzification methods; business performance; SCM; supply chain management; modelling.
