Purpose

To avoid sub-optimization in wheat storage centers, one of the most strategic facilities, it is necessary to review and relocate them to be optimized regularly. The present study aims to propose an integrated method using geographic information systems (GISs) and an appropriate weighting algorithm for the relocation of wheat storage facilities.

Design/methodology/approach

To achieve the goal mentioned above, sustainability pillars in facility location and relocation are initially developed; afterward, a set of suitable criteria are obtained from various scientific resources. Then, the weight of each sustainable development pillar and its corresponding sub-criteria were identified through utilizing the best–worst method (BWM). By applying the obtained weights in the ArcGIS software package, various geographical layers were designed, and land-use planning, logistics planning and sustainable logistics planning are carried out in the regions. The regions are ranked based on the scores obtained in the processes, and the best regions are selected for sustainable relocation problem.

Findings

A case study including 430 regions (counties) in Iran is conducted to evaluate the efficiency of the suggested approach. The study results indicate that Iran possesses a superior state for establishing wheat storage centers in terms of infrastructural and social aspects. Also, it is established that 16% of counties are recognized as sustainable locations for relocating the wheat storage facilities.

Research limitations/implications

There is no most suitable analysis of the wheat storage facilities, as well as their strategic position in the supply chain, and there is a lack of considering sustainability in wheat storage facility location, despite the particular importance of it to the supply chain.

Practical implications

This framework is applied in an Iranian wheat-bread supply chain to find the best sustainable facilities. It is noted that this algorithm can be applied in other strategic facilities by minor and some major changes.

Originality/value

Decision-makers can apply the proposed methodology to find the best relocation sites for wheat storage facilities as the main part of wheat-bread supply chain in order to prevent sub-optimization and improve the efficiency of their supply chain.

使用 GIS 和最佳-最差方法在农业系统中进行可持续设施搬迁

目的

为避免小麦仓储中心这一最具战略意义的设施之一出现次优，有必要对其进行审查和搬迁，以便定期进行优化。本研究旨在提出一种使用地理信息系统 (GIS) 的综合方法和适当的加权算法，用于小麦储存设施的搬迁。

设计/方法/方法

为实现上述目标，初步制定了设施选址和搬迁方面的可持续性支柱；随后，从各种科学资源中获得了一套合适的标准。然后，通过使用最佳-最差方法（BWM）确定每个可持续发展支柱的权重及其相应的子标准。应用ArcGIS软件包中获得的权重，设计各种地理图层，在区域内进行土地利用规划、物流规划和可持续物流规划。根据过程中获得的分数对区域进行排名，并选择最佳区域来解决可持续搬迁问题。

发现

进行了包括伊朗 430 个地区（县）的案例研究，以评估所建议方法的效率。研究结果表明，伊朗在基础设施和社会方面拥有建立小麦储存中心的优势。此外，确定 16% 的县被认为是重新安置小麦储存设施的可持续地点。

研究限制/影响

对小麦储存设施及其在供应链中的战略地位没有最合适的分析，并且缺乏考虑小麦储存设施选址的可持续性，尽管它对供应链特别重要。

实际影响

该框架应用于伊朗小麦面包供应链，以寻找最佳的可持续设施。需要注意的是，该算法可以通过微小和一些重大变化应用于其他战略设施。

原创性/价值

决策者可以应用所提出的方法来寻找小麦储存设施的最佳搬迁地点，作为小麦面包供应链的主要部分，以防止次优并提高供应链的效率。
