We discuss the effects of inflation and time discounting on an EOQ model for deteriorating items under stock-dependent demand and time-dependent partial backlogging. The inventory model is studied under the replenishment policy starting with no shortages. We then use MATLAB to find the optimal replenishment policies. The objective of this model is to maximize the total profit (TP) which inclu...

a r t i c l e i n f o This paper expands an inventory model for deteriorating items with stock-dependent demand. This model provides time varying backlogging rate as well as time varying deterioration rate. The aim of this model is to determine the optimal cycle length of each product such that the expected total cost (holding, shortage, ordering, deterioration and opportunity cost) is minimize...

Environmentally friendly goods are market-oriented that create less environmental damage. Their manufacture is related to a product development process designed consider the consequences might develop throughout their life cycle. In reality, global demand for herbal expanding since products manufactured from plant extracts such as leaves, roots, flowers, and seeds, among others, cause destructi...
