• EOQ INVENTORY MODEL FOR TIME DEPENDENT DETERIORATING ITEMS WITH QUADRATIC TIME VARYING DEMAND, TWO PARAMETER WEIBULL DETERIORATION AND PARTIAL BACKLOGGING

R. KAVITHA PRIYA*, Dr. K. SENBAGAM

Abstract


Perishable goods are modelled in an inventory model with a known fixed lifetime or with a random lifetime. We have considered an inventory model with random lifetime that is, the deterioration rate follows a two parameter Weibull distribution. The demand rate is assumed to be a quadratic function of time. The shortages are allowed. All demands are satisfied immediately by partial backlogging.The proposed model is approved with a numerical example. The sensitivity analysis is provided to examine the impact of changes with the variation in the parameters each at a time on the optimal solution.


Keywords


Deteriorating items, Weibull distribution, quadratic demand, shortages, partial backlogging.
