摘要

我们制定并求解了一个混合整数线性规划,以模拟农业产业生产者和批发商之间的农业综合企业两级供应链。所提出的模型是一个等效的双层线性规划的重新表述,使用了众所周知的KKT条件和对互补约束的析取方法。它包括一个分层决策结构,考虑到上层的农业工业生产者,他们通过将田地划分为管理区并为每个管理区分配特定的作物轮作计划来最大化其利润。反过来,在较低的层次是批发商,他最小化了损失销售的惩罚成本,可以根据生产商提供的单位进行实验,以满足需求要求。我们提出了一个案例研究,以显示所提出的方法的相关性。

A mixed-integer linear optimization model for a two-echelon agribusiness supply chain

We formulate and solve a mixed-integer linear program to model an agribusiness two-echelon supply chain between an agro-industrial producer and a wholesaler. The presented model is an equivalent reformulation of a bilevel linear program, using the well known KKT conditions and a disjunction approach on the complementary constraints. It includes a hierarchical decision structure that contemplates an agro-industrial producer in the upper level, who maximizes its profit by delineating the field into management zones and assigning to each one a specific crop rotation plan. In turn, in the lower level is the wholesaler who minimizes the penalization cost of lost sales that could experiment in order to satisfy the demand requirement according to the units provided by the producer. We present a case study to show the relevance of the proposed methodology.

期刊介绍: Electronic Notes in Discrete Mathematics is a venue for the rapid electronic publication of the proceedings of conferences, of lecture notes, monographs and other similar material for which quick publication is appropriate. Organizers of conferences whose proceedings appear in Electronic Notes in Discrete Mathematics, and authors of other material appearing as a volume in the series are allowed to make hard copies of the relevant volume for limited distribution. For example, conference proceedings may be distributed to participants at the meeting, and lecture notes can be distributed to those taking a course based on the material in the volume.
