چکیده

vendor managed inventory is a continuous replenishment program that is designed to provide major cost saving benefits for both vendors and retailers. previous research on this area mainly included single objective optimization models where the objective is to minimize the total supply chain costs or to maximize the total supply chain benefits. this paper presents a bi-objective mathematical model for single-manufacture multi-retailer with multi-product in order to maximize their benefits. it is assumed that demand is a decreasing and convex function of the retail price. in this paper, common replenishment cycle is considered for the manufacturer and its retailers. then, the proposed model converts to the single-objective optimization problem using a weighted sum method. a genetic algorithm (ga) is applied to solve it and response surface methodology is employed to tune the ga parameters. finally, several numerical examples are investigated to demonstrate the applicability of the proposed model and solution approach.

A Bi-objective Optimization for Vendor Managed Inventory Model

Vendor managed inventory is a continuous replenishment program that is designed to provide major cost saving benefits for both vendors and retailers.

Optimizing a bi-objective vendor-managed inventory of multi-product EPQ model for a green supply chain with stochastic constraints

In this paper, a bi-objective multi-product single-vendor single-buyer supply chain problem is studied under green vendor-managed inventory (VMI) policy based on the economic production quantity (EPQ) model. To bring the model closer to real-world supply chain, four constraints of model including backordering cost, number of orders, production budget and warehouse space are considered stochasti...

Two parameter tuned multi-objective evolutionary algorithms for a bi-objective vendor managed inventory model with trapezoidal fuzzy demand

This paper presents a bi-objective vendor managed inventory (BOVMI) model for a supply chain problem with a single vendor and multiple retailers, in which the demand is fuzzy and the vendor manages the retailers’ inventory in a central warehouse. The vendor confronts two constraints: number of orders and available budget. In this model, the fuzzy demand is formulated using trapezoidal fuzzy num...

Developing EOQ model with instantaneous deteriorating items for a Vendor-Managed Inventory (VMI) system

This paper studies the economic-order-quantity model (EOQ) for deteriorating items in two cases (with and without shortages) to evaluate how vendor managed inventory (VMI) affects supply chain. We consider two-level supply chain (single supplier and a single retailer) with one instantaneous deteriorating item. A numerical example and sensitivity analysis are provided to illustrate the effect of...

An Inventory Model for Deteriorating Items Using Vendor-Managed Inventory Policy

In recent researches, vendor managed inventory (VMI) policy is rarely considered for deteriorating items.   This study considered the supply chain partner’s collaboration via a VMI system and provided an EOQ model for a two-level supply chain (single supplier - single retailer) to examine the inventory management proceedings for VMI and non-VMI supply chains. By a new approach in modeling, the ...

Vendor Managed Inventory of a Supply Chain under Stochastic Demands

In this research, an integrated inventory problem is formulated for a single-vendor multiple-retailer supply chain that works according to the vendor managed inventory policy. The model is derived based on the economic order quantity in which shortages with penalty costs at the retailers` level is permitted. As predicting customer demand is the most important problem in inventory systems and th...
