In today’s globalized world the number of risks in supply chains are increasing and the threats are becoming more complex. All the risks and threats can have a severely negative impact on markets. Some of these threats are terrorism, piracy and theft. Within the food industry, Food Terrorism has gained relevance due to the extreme consequences it may have on both public health and the market. Food Terrorism refers to the intentional contamination of food in any link of the supply chain, which covers everything from production to consumption. The Food Defense refers to the analysis, control and improvement of prevention mechanisms of those attacks; that is, the Food Defense involves a Risks Management. In general terms, this paper focuses on a proposal formulation based on a risk analysis that allows establishing a management system for preventing intentional food contamination and the improvement of the security of the supply chain. Given the recent events in Paris, on November 13, 2015, consideration has also been given to the present situation and the importance of the issue of preventing terrorism.This initial study covers only the theoretical methodological proposal and focusses only on the companies of the alimentary sector of Guanajuato State in Mexico. However, it may extend into a research plan security of food supply chain.

Reasignación óptima del inventario a pedidos en empresas cerámicas caracterizadas por la falta de homogeneidad en el producto (FHP) La Falta de Homogeneidad en el Producto (FHP), se define como la carencia de la homogeneidad requerida por el cliente en los productos. La FHP aparece en empresas en las que los productos finales obtenidos no son homogéneos, dando lugar a la existencia de diferentes referencias (subtipos) de un mismo producto final. Esta falta de homogeneidad supone un problema cuando el cliente requiere ser servido a través de unidades homogéneas de un mismo producto y sus pedidos se comprometen en base cantidades planificadas, cuyas características de homogeneidad finales se desconocen en el momento de adquirir los compromisos con el cliente. Las constantes discrepancias provocadas por la FHP entre las cantidades planificadas y las realmente obtenidas y disponibles, pueden impedir servir pedidos comprometidos previamente. Para resolver este problema, se propone un modelo de programación matemática que permite reasignar el inventario en empresas caracterizadas por la FHP que fabrican contra almacén (Make to Stock: MTS) que combina varios objetivos. El modelo matemático propuesto se ha validado mediante su aplicación a un caso real de una empresa cerámica. El análisis de los resultados indica la obtención de mejoras considerables en la cantidad de pedidos completados a tiempo y en los ingresos por ventas.M Palabras clave: Asignación de inventario, disponible a prometer (ATP), falta de homogeneidad en el producto (FHP), fabricación contra stock (MTS), modelo de programación matemática, múltiples objetivos.Optimal inventory reallocation to customer orders in ceramic tile companies characterized by the lack of homogeneity in the product (LHP)The lack of homogeneity in the product (LHP) is defined as the lack of uniformity required by the customer in the products. The LHP appears in companies where the final products obtained are not homogeneous, leading to the existence of different references (subtypes) of the same product. This lack of homogeneity is a problem when the client needs to be served through homogeneous units of a product and commit orders are based on planned quantities, whose final homogeneity characteristics are unknown at the time of acquiring the customer commitments. The frequent discrepancies caused by the LHP between planned homogeneous amounts and those actually obtained and available, can prevent the delivery of committed orders. To solve this problem, we propose a mathematical programming model for the reallocation of inventory in Make to Stock (MTS) ceramic tile companies characterized by the LHP that combines multiple objectives. The proposed mathematical model has been validated by its application to a real case of a ceramic company. The analysis of the obtained results indicates significant improvements in the number of orders completed on time and in sales revenue achieved.
