Abstract

Food production systems are complex industrial operations that often involve multiple parties. This study proposes inventory management strategies for a multi-echelon perishable food supply chain with growing and deteriorating items. The upstream end of the proposed food supply chain is the farming echelon where newborn growing items are reared to maturity. Following this, the items are sent to the processing echelon for processing, a term that collectively describes activities such as slaughtering, cutting and packaging. The aim of the processing echelon is to transform live growing items into processed food products that are suitable for human consumption. The downstream end of the supply chain is the retail echelon where consumer demand for processed food products is met. Once the items are processed, they are subject to deterioration at both the processing and retail echelons. In light of this, an integrated inventory model aimed at optimising the performance of the entire food supply chain is formulated. The impact of investing in preservation technologies is also investigated due to the perishable nature of food products. To do this, a secondary model that incorporates an investment in preservation technologies is formulated. The model, representing a simplified industrial food production system, is aimed at jointly optimising the lot-size, number of shipments, growing cycle duration, processing cycle duration and the preservation technology investment amount. The results from the numerical example demonstrate that the preservation technology investment is worthwhile because it results in reduced inventory management costs across the supply chain.

在涉及生长和变质物品的三级食品供应链中,保存技术投资对批量和运输策略的影响
食品生产系统是复杂的工业操作,通常涉及多方。本研究提出了一个多层次易腐烂食品供应链的库存管理策略。所提出的食品供应链的上游端是农业梯队,在那里,新生生长的物品被饲养到成熟。在此之后,这些物品被送到加工梯队进行加工,这个术语统称为屠宰、切割和包装等活动。加工梯队的目的是将活的种植项目转化为适合人类消费的加工食品。供应链的下游是零售梯队,消费者对加工食品的需求在这里得到满足。一旦物品被加工,它们就会在加工和零售梯队中变质。基于此,本文提出了一个旨在优化整个食品供应链绩效的综合库存模型。由于食品的易腐性,对保鲜技术投资的影响也进行了调查。为了做到这一点,我们制定了一个包含保存技术投资的二级模型。该模型代表了一个简化的工业食品生产系统,旨在共同优化批量、发货量、生长周期、加工周期和保鲜技术投资金额。数值算例的结果表明,在整个供应链中,仓储技术的投资是值得的,因为它降低了库存管理成本。
