Abstract
The globalization has generated changes in world food consumption, demand for healthy foods as fresh fruits and vegetables have increased. The losses in the perishable fruit supply chains can reach up to 40%, the post-harvest loss in Colombia is mainly due to the inadequate planning and execution of the inventory processes. The problem is due to the high perishability of the fruit and its variabil-ity in terms of quality levels, which even under optimal conditions ofstorage tend to decrease. After reviewing publications in the field of inventory management of perishable goods, there is no research regarding fruit supply chain. Additionally, some models do not cover the entire supply chain, and they only focus in studying one or two actors involved in the chain. This article presents a management mod-el of multi-level inventory for fruit mango chain includes functions decay and own losses of highly perishable fruit, a model nonlinear programming, formulated and evaluated in GAMS, which minimizes the total cost of inventory in the chain formed by a farmer, an agro-industrial company, a wholesaler, a hypermarket, a reseller and a retailer allowing calculate the order quantity and time of optimal re-placement of fruit for each echelon.
Highlights
Controlling inventory is one of the most important logistics operations in agricultural supply chains (Coelho & Laporte, 2014; Qin et al, 2014; Chung et al, 2014; Duan & Liao, 2013; Salin, 1998) especially for products such fruits and vegetables, due to the high rate of perishability of these kinds of goods
Fresh fruits even decrease their quality when they are in motion, and fruits offer is seasonal which leads to a volatile demand (Soto-Silva et al, 2016), permitting consumer choice to be influenced by the availability of the fruit at the time of purchasing and the quality thereof, (Yang & Wee, 2003; Akkerman et al, 2010; Van Der Vorst, 2006; Duan & Liao, 2013)
Food supply chains are global complex networks, covering production, processing, distribution, and even elimination of damaged food (Yu & Nagurney, 2013) in which logistics operations become important for agribusiness management, since all of these types of goods are perishable and its short life cycle makes inventory management a critical aspect (Orjuela-Castro et al, 2017)

As result of reviewing the state of the art, we used as a base for our research the works done by (Rau et al, 2003) and (Wang et al, 2011) who considered the behavior of inventory management for perishables In this research those studies were supplemented by particular variables in the formulation of a model, for inventory management in the Mango supply chain in Cundinamarca-Bogotá, we included some constraints not contemplated before, as well as the model covers six echelons of the fruit supply chain, not done before. The model permits to calculate the losses due to the time in inventories elapsed of the different actors, to be accumulated and compared with the life cycle of the fruit, after of harvest
