A Fuzzy Inventory Model of Defective Items Under the Effect of Inflation with Trade Credit Financing

Cost optimization inventory model for deteriorating items with trapezoidal demand rate under completely backlogged shortages in crisp and fuzzy environment

“…Nevertheless, the selling price dependent demand assumed by Sahoo et al [40] for linear deteriorating items, and Khanna et al [21] for imperfect quality and constant deteriorating items in their proposed problems. Moreover, both advertising cost and price dependent demand were discussed by Chanda and Kumar [7] for fashionable products, Shaikh et al [43,44] for Weibull and constant deteriorating items, and Kumar et al [23] for defective products. Rajan and Uthayakumar [36], and Kaliraman et al [18] developed inventory models for constant deteriorating items under exponentially growing demand.…”

“…Thus, many researchers in the present era have considered the impreciseness of the parameters for the inventory requirements in the fuzzy environment. For some developments in this direction, see the recent works of Chanda and Kumar [7], Sharma et al [46], Indrajitsingha et al [12][13][14], Mishra et al [32], Shaikh et al [43], Kumar et al [23][24][25], Nayak et al [35], Routray et al [39] and Shabani et al [42]. Apart from these, the government and various companies are changing their policies from time to time, which also lead to fuzziness in inventory models.…”

“…To deal with such imprecisions, numerous researchers have already used fuzzy approaches and achieved the best outcomes. In the recent past, Indrajitsingha et al [8] and Kumar et al [17] explored inventory models for constantly decaying items with corresponding pricedependent demand and selling-price-advertisement cost demand with an account of imprecision in associated parameters in fuzzy environments. For a fuzzy inventory model of Weibull degrading products, Nayak et al [31] proposed a suitable model for entirely backlogged shortages.…”
