Two Level Storage Inventory Model with Ramp Type Demand under Inflationary Environment with Partial Backordering

Vineet Kumar, Sudesh Kumar Garg, Soniya Gupta, Sanjay Kumar Sharma

[ABSTRACT ]

A two level storage inventory model is constructed in this article. It is well known that the demand for seasonal
products (such as fur coats) increases at the beginning of the season until a certain period of time and stabilizes
into a fixed amount of time for the rest of the season. To store these extra parts for the buyer arrange additional
storage space. This model uses a ramp type demand rate, variable deterioration and shortages are partially
backlogged using a variable backordering rate. The entire research is conducted in an inflationary environment.
The goal of this model is to reduce the system's total average cost. A numerical assessment and sensitivity
analysis are used to verify the suggested model's optimal solution.

Keywords: Two-warehouse, ramp type demand rate, partial backlogging, inflation, time varying deterioration.
