The supply chain of agricultural has received a great deal of attention lately due to issues related to public health. Something that has become apparent is that in the near future the design and operation of agricultural supply chains will be subject to more stringent regulations and closer monitoring, in particular those for products destined for human consumption (agri- foods). The supply chain of agri-foods, as any other supply chain, is a network of organizations working together in different processes and activities in order to bring products and services to the market, with the purpose of satisfying customers‟ demands.This work is concerned with the planning of a real agri-food supply chain for poultry products. For this concrete case we chose two products namely chicken and turkey-cock meat. More precisely the problem is to redesign the existing supply chain and to optimize the distribution planning. Furthermore, environmental costs of road transportation in terms of CO2 emissions are taken into account in the computations. The proposed integrated approach permits to minimize the total costs of the agri-food supply chain not only in terms of economy but also in terms of public health (ecology). As mentioned in our paper, the entire problem is decomposed into two problems, and each sub problem is solved in sequential manner, to get the final solution. LINGO optimization solver (Version12.0) has been used to get the solution to the problem.. Keywords— Agri_food Supply chain; distribution network; optimization; CO2 emissions. I. INTRODUCTION The study of supply chains and networks has grown rapidly as an area of academic interest from the early 1990s onwards. Economic, sociologists and management scholars acknowledged that studying firms individually could not sufficiently explain real life phenomena and did not lead to useful recommendation for partitioners. Agri-food supply chains (ASC) is the term used to define logistics networks which encompasse production and distribution activities of agricultural or horticultural products from the farm to the consumers, see [1]. In particular the management of perishable products is a relevant issue in the ASC management domain, since the sellers cannot wait for the best favourable market conditions unless the quality and safety of their products deteriorate, see [17]. These products must therefore be rapidly shipped from the sellers to the customers. Moreover the demand of consumers on healthy products is ever increasing and regulations of the authority are more and more stringent. In addition to these factors, the variability in the demand and price of these products with limited shelf life adds complexity to the supply planning of these already critical supply networks. This explains the growing attention paid to the ASC in the literature, see [4]. ASC are formed by the organizations responsible for production (farmers), distribution, processing, and marketing of agricultural products to the final consumers. The supply chain of agri-foods, as any other supply chain, is a network of organizations working together in different processes and activities in order to bring products and services to the market, with the purpose of satisfying customers’ demands [2]. The aim of this work is coordination of decisions for location, allocation and transportation of products to achieve an efficient and green logistic network design and distribution planning. The approach chosen is a location-routing formulation which consists in addressing a vehicle routing problem in which the optimal number and location of the slaughterhouses are to be determined simultaneously with the distribution routes to the customers in order to minimize the total costs [3]. The study of agri-food chains and networks can be divided into three streams [18]. One stream is supply chain management Food safety has become the subject of significant public and regulatory attention in various countries. Food safety is often an experience or credence attribute that consumers cannot detect through search activities prior to purchase [5]. The handling and consumption of poultry meat is recognized as a major cause of foodborne illness in humans globally particularly when eaten raw, undercooked or recontaminated and stored following cooking [17]. This implies that the traditional supply chain practices may be subject to revision and change. One of the aspects that may be the subject of considerable scrutiny is the planning activities performed along the supply chains of agricultural products. This study is an extension of a published work, where we add the cost of waste degradation to protect the environment. II. STATE OF THE ART Supply-chain management (SCM) is the integrated planning, coordination and control of all business processes and activities in the supply chain to deliver superior consumer value at least cost to the supply chain as a whole while
