Modeling of a Three-Echelon Supply Chain: Stability Analysis and Synchronization Issues
نویسندگان
چکیده
This paper introduces the supply chain networks integration and discusses the interest of synchronization within them. The evaluation of the causes of uncertainties within the supply chain networks is considered. The structure of a threeechelon supply chain is envisaged and the modeling of this structure is carried out. It is shown that the supply chain network can be exposed to both external and internal perturbations. The origin of these perturbations is discussed and it is shown that the stability of the supply chain network is very sensitive to these perturbations. The effects of the external perturbations on the supply chain network are considered. It is shown that these perturbations can saturate the supply chain network and also create bullwhip effects and chaotic phenomena within the network. A method is developed which is based on an adaptive algorithm for the automatic cancellation of the effects of external perturbations by re-adjusting the internal thresholds of the supply chain network in order to achieve synchronization. Some additional insights into theory and practice in supply chain managements are provided. Keywords—Synchronization; Supply chain networks; Supply chain network control; Supply chain optimization; Bullwhip effect; Chaos in supply chains

MODELING RISK OF LOSING A CUSTOMER IN A TWO-ECHELON SUPPLY CHAIN FACING AN INTEGRATED COMPETITOR: A GAME THEORY APPROACH
In a competitive market, customer decision is made to maximize his utility. It can be assumed that risk of losing a supply chain’s customer can be defined based on products utility from customer point of view. This paper takes account of product price and service level as competition criteria. The proposed model is based on non-cooperative game theory, for one-manufacturer and one-retailer supp...
متن کاملDetermination of a Desirable Inventory Policy in a three Echelon Multilayer Supply Chain with Normal Demand
Inventory control is one of the most important issues in supply chain management. In this paper, a three-echelon production, distribution, inventory system composed of one producer, a set of wholesalers and retailers is considered. Costumers' demands can be approximated by a normal distribution and the inventory policy is a kind of continuous review (R, Q). In this paper, a model based on stand...

In this paper,we investigate the pricing and return policy issueof one-echelon green supply chain, contain a manufacture who produces two type of products: green and non-green products. These products have a same functional but in selling price and environmentally issues have different effects. Also we consider return policy for both products that can stimulate the customer valuation. We develo...
متن کاملOptimization of Multi-period Three-echelon Citrus Supply Chain Problem
In this paper, a new multi-objective integer non-linear programming model is developed for designing citrus three-echelon supply chain network. Short harvest period, product specifications, high perished rate, and special storing and distributing conditions make the modeling of citrus supply chain more complicated than other ones. The proposed model aims to minimize network costs includin...
متن کاملCoordinating Orders in Three-echelon Supply Chain using price adjustment mechanism
Supply chain coordination has become a critical success factor for supply chain management (SCM). In the past few years, the researchers have widely emphasized that cooperation among supply chain (SC) firms is a key source of competitive advantage. This paper is focused on supply chain coordination from the perspective of inventory management. Li and Liu [1] developed a model for illustrating h...
