Logistics network configuration for seasonal perishable food supply chains

Purpose: The logistics network design (LND) lead to different supply, storage and distribution process and result in the flows, these logistics operations have an impact on the performance of the chain of fresh agricultural products. Specifically, in the perishable food supply chain (PFSC) with seasonality, a temporary imbalance between supply and demand is generated, which affects the balance in the flows and affects the losses, costs and response capacity. The location of stakeholders, production, transformation, commercialization and distribution facilities generate the configuration of the PFSC. Likewise, seasonality affects flows and decisions made by actors, which would generate the need to change the configuration of the PFSC. This research proposes a multi-objective, multi-product, multi-echelon for LND model in seasonal PFSC from a developing country with a topography of mountain ranges, where trucks don’t refrigerated and inadequate packaging used allow the food to be affected by the variations in altitude, changes in temperature (T0) and relative humidity (RH). The model was evaluated through a case study in fresh fruits. Design/methodology/approach: Tow mixed linear programming (MILP) multi-objective sub-models are established that determines the multiple configurations of the logistics network of the PFSC with seasonally and allows stakeholders to approach efficiency frontiers, which contribute to their permanence in the markets. The model was applied to the case of the perishable fruit supply chain, in a developing country, Colombia. The population information was taken from government surveys and studies, which allowed parameterizing the model. Findings: The application of model permitted to answer the next questions: How does improve the performance from seasonal PFSC through logistics network design? And, How the existence of smallholdings in food production and from retail merchants is preserved? It is necessary, on this context of the seasonal perishable food supply chain, to propose a model that changes its objectives in times of oversupply or shortage. Specifically, on a developing country with a topography of mountain ranges, where don’t used refrigerated trucks nor adequate packaging. Social implications: Due the perishable food supply chain stakeholders are located in non-efficient borders and their permanence in the markers may be affected by competition, must be guaranteed the existence of smallholdings farmers and small retail merchants avoiding monopolies. What contributes on increasing food availability and improve access and therefore food security. the stakeholders should focus on increasing food availability and reducing losses to improve access and therefore food security. Originality/value: Due the seasonality of agricultural products tht generates an imbalance between supply and demand, a new methodology for the change logistics network configurations of seasonal perishable fruit supply chain was development, the optimizing from five objectives with two multi-objective sub-models is obtained. One for surplus and the other for de deficit moments. The methodology includes real conditions, such as, fruit loss due T0 and RH by different thermal floors, packing and the means transport not refrigerated used, in mountain areas at countries in route of development. The impact over the small producers, retailers and consumers in the times of scarcity or surplus was analyzed
