Research on optimization model of transport network for exported agricultural products

Abstract

The export of agricultural products plays an increasingly vital role in Vietnam’s economy, thereby intensifying the demand for efficient logistics network design - particularly for perishable goods such as fresh durians. This paper provides a comprehensive review of transportation network optimization studies, with a specific focus on multi-objective Mixed-Integer Linear Programming (MILP) model. It further proposes a model initialization framework tailored to practical conditions. The suggested model facilitates the concurrent optimization of transportation costs and time within a four-tier logistics network, integrating variables, parameters and restrictions that represent the framework of the export-oriented agricultural supply chain. Although empirical data has not yet been applied, the model serves as a foundation for future data collection and operational planning, particularly for tackling the transportation issue of durian exports from Daklak to China.

Keywords: Agricultural supply chain; logistics for perishable goods; multi-objective MILP model.
