the optimal strategy for integrated vendor-buyer inventory model with
fuzzy annual demand and fuzzy adjustable production rate. This model with
such consideration is based on the total cost optimization under a common
stock strategy. However, the supposition of known annual demand and adjustable
production rate in most related publications may not be realistic. This
paper proposes the triangular fuzzy number of annual demand and adjustable
production rate and then employs the signed distance, to find the estimation
of the common total cost in the fuzzy sense and derives the corresponding
optimal buyer’s quantity consequently and the integer number of lots
in which the items are delivered from the vendor to the purchaser. A numerical
example is provided and the results of fuzzy and crisp models are compared.]]>Chang, H.C.,2004Chen, S.H. and C.C. Wang,1996Goyal, S.K.,1988Ha, D. and S.L.
