In this paper we have developed a continuous review inventory model for deteriorating items with time dependent demand rate. Deterioration rate is increasing with time. Each cycle has shortages, which have been partially backlogged. The backlogging rate is taken to be inversely proportional to the waiting time for the next replenishment. Fuzziness is introduced by considering demand rate and pa...

Global warming and climate change become a sensitive issue worldwide, many countries try to control the CO 2 emissions by investigating in projects. This study proposes sustainable inventory model reduce carbon emission. It is generally assumed that demand increasing at starting of an level decreasing ending for particular newly launched product. In this situation, usually represented Normal di...

Different from the previous articles on multi-echelon deteriorating inventory, this paper explains economic implications of Weibull parameters for cold chain inventory rather than restricting to mathematical sense. A case study shows that DC warehousing activities and total throughput scale factor has a significant effect profit compared with storage technology environment shape factor. The imp...
