Quantity discount for integrated supply chain model with back order and controllable deterioration rate

Abstract

Due to uncertainty in economy, business players examine different ways to ensure the survival and growth in the competitive atmosphere. In this scenario, the use of effective promotional tool and co-ordination among players enhance supply chain profit. The proposed model deals with the effect of quantity discount on an integrated inventory system for constantly deteriorating items with fix life time. We use advertisement and quantity discount to accelerate stock dependent demand and further, the offered preservation technology for controlling deterioration rate. The model is validated numerically, and the sensitivity analysis for critical supply chain parameters is carried out. The results can be used in the decision making process of the supply chains associated with the supply of cosmetic, tinned food, drugs, and other FMCGs.

Fuzzy Inventory Model for Deteriorating Items With Low Carbon Emission Cost Under Preservation Technology and Trade Credit

“…To establish optimality, taking the necessary conditions ∂F TC p1 (T,τ) ∂T = 0 and ∂F TC p1 (T,τ) ∂τ = 0. Accordingly, by taking first order partial derivative of the equation (15) with respect to T and τ and equating to zero, the optimal values of T and τ are obtained as T * and τ * . After substituting these values in equation ( 15), we get total cost of the system.…”

“…They take into consideration sustainability at the backdrop of joint trade credit, where demand pertains to the credit period. Later, Daryanto and Wee [6], Patel et al [7], Karthick and Uthayakumar [11], Malleeswaran and Uthayakumar [14], Mishra and Talati [15], Yu et al [21], and Tao and Xu [22] addressed carbon emissions under various assumptions.…”

Innovative Approach of EOQ Structure for Decaying Items with Time Sensitive Demand, Cash- Discount, Shortages and Permissible Delay in Payments

“…Jaggi et al [19] offered a model, including selling price dependent demand under deterioration. Mishra and Talati [20] proposed a single set-up multiple deliveries for fading stuff with fixed life time.Jani et al [21] have studied an inventory policy for the item which has expiry date with two levels of trade credit depending on the quantity of order. It is considered that a supplier is ready to give a mutually agreed credit period to retailer only if the order quantity purchased by retailer is more than the predetermined quantity of ordered.…”
