Abstract: This paper presents an optimal control recovery production inventory system with shortages under inflation and discounting in fuzzy-stochastic environment. The product defectiveness is random. The defective product also is treated as return product. Remanufactured product can be used for assembly of new products, which is sold again. Return and defective products are either remanufactured or disposed of. The demand depends on the stock of serviceable product and time. In this paper, an optimal control approach is proposed to optimise the production, remanufacturing and disposal strategy with respect to demand and dynamic return. The upper bound of production, remanufacturing and disposal are fuzzy parameters. The optimum results are presented both in tabular form and graphically. In particular, the production process without and only with remanufacturing system is presented.
