SAHOO 1 C. K.SAHOO 1 A. KALAM 2 Institute of Mathematics & Application, Andharua, Bhubaneswar - 751003, Orissa (INDIA) Department of Mathematics, Gandhi Institute for Technology, Bhubaneswar -Orissa (INDIA) <p style="text-align: justify;">In this paper present inventory constant production system for Weibull deteriorating items has been developed with demand rate as a ramp type function of time. The finite production rate is proportional to the demand rate and deterioration rate. The constant production cost of inversely proportional to the demand rate. The model without shortage case in inventory solved here. Sensitivity of the decision variables to changes in the parameter values is examine and affect of these changes on the optimal policy are discussed and numerical examples presented to illustrate the model developed.</p> https://ultraphysicalsciences.org/paper/1388/ Ramp type demand Weibull deterioration unit production cost without shortage Demand.
