“…Wang and Li [16] defined quality decay as a key factor for perishable food and introduced it into a dynamic pricing strategy to control the product quality in the supply chain. Mohapatra and Roy [17], Keizer et al [18], and Ferrer et al [19] captured the average decay of heterogeneous agri-products by means of statistical methods. The freshness function refers to describing the relationship between the freshness of agricultural products and time from a positive perspective.…”

With the rise of vegetable online retailing in recent years, the fulfillment of vegetable online orders has been receiving more and more attention. This paper addresses an integrated optimization model for harvest and farm-to-door distribution scheduling for vegetable online retailing. Firstly, we capture the perishable property of vegetables, and model it as a quadratic postharvest quality deterioration function. Then, we incorporate the postharvest quality deterioration function into the integrated harvest and farm-to-door distribution scheduling and formulate it as a quadratic vehicle routing programming model with time windows. Next, we propose a genetic algorithm with adaptive operators (GAAO) to solve the model. Finally, we carry out numerical experiments to verify the performance of the proposed model and algorithm, and report the results of numerical experiments and sensitivity analyses.

Abstract:The unique characteristics of perishable agri-products are a short lifespan and rapid quality deterioration. This establishes the need to significantly reduce the time from harvest to distribution. These features require reducing the processing time from harvest to distribution to being as short as possible. In this study, we focus on an integrated perishable agri-products scheduling problem that combines harvest and distribution simultaneously, with the purpose of reducing processing time and quality decay. We propose this problem as a mixed integer nonlinear programming model (MINLP) to optimize the harvest time and the vehicle routing to consumers, and this MINIP is formulated as a vehicle routing problem with time windows (VRPTW). We introduce a big M method to transform the nonlinear model into a linear model, then apply CPLEX to solve the transformed model. Numerical experiments and sensitive analysis are conducted to verify the efficiency of the proposed model and to provide managerial insights.

“…Lifetime in the sense the time after which items are not be useful for consumption.That is the reason perishable items like fruits and vegetables need more care and attention towards the management of inventory. Moreover these products have some special characteristics like rise and fall in demand, less and uncertain life time and customer view towards the quality and durability of the products which makes the inventory different than the nonperishableproduct [1][2][3][4][5][6][7]. Taparia, Rajashree et al [8] has discussed the model predictive control strategy to minimize the shortage cost and maximize the profit by formulating the cost function in optimum way, also to derive the replenishment control law MPC strategy has been used.…”

Inventory management becomes a challenge when it comes to perishable goods. In practice managing perishable goodsis a difficult task worldwide.Improvement of inventory control of perishable goods depends on the model chosen or implemented. This paper proposes how to improve the profit and to reduce the risk of spoiling the goods with respect to the rate of decay which may be fixed or variable. By considering a specific type of perishable goods this experimental investigation has been done based on linear decay and exponential decay. It has been observed that irrespective of the type of decay, the energy level in forward approach is far better than the back approach of consuming the perishable goods.
