Abstract

Countries’ defence industries are the leading indicator of their global power. The warehouse is the place where the materials are kept until the customer order arrives so that the companies are viable and can respond appropriately to internal/external customer demands. In this regard, warehouse location plays a vital role in the defence industry in terms of storage options with increased flexibility, a simplified supply chain with cost management and optimal positioning according to deployment locations. In this study, the decision on the location of warehouses for logistic support during the warranty period of military vehicles manufactured and supplied to the armed forces by a defence company was made. It is aimed to propose the best solution to a real-life problem with high complexity, containing many data and constraints. In this context, the criteria that are thought to be most relevant to this problem have been determined by taking expert opinions. Having determined the order of importance of the requirements by the analytical hierarchy process (AHP) with the Super Decisions V 2.10, their weights were included as a coefficient of the objective function in the goal programming (GP) model. As a result of solving the GP model using GAMS (general algebraic modelling system), it was decided to select the warehouses that provided the optimal results among the alternative warehouse locations in 9 different locations. Furthermore, to see the impact of changes in criterion weights, sensitivity analysis has also been included. The significance of this research lies within the integrated usage of AHP and GP in the defence industry when determining warehouse locations by the experts’ opinions. With this study, not only a solution strategy was developed, but also a basis for the warehouse location decision in the defence industry projects already signed or to be signed was given.
国防工业组织中仓库最佳位置的集成建模方法
一个国家的国防工业是其全球实力的主要指标。仓库是在客户订单到达之前保存材料的地方,以便公司能够生存并能够适当地响应内部/外部客户的需求。在这方面,仓库位置在国防工业的存储选择方面发挥着至关重要的作用,具有更高的灵活性,简化的供应链,成本管理和根据部署位置的最佳定位。在这项研究中,决定了一家防务公司制造和供应给武装部队的军用车辆在保证期内后勤支助仓库的地点。它旨在为现实生活中具有高复杂性、包含许多数据和约束的问题提出最佳解决方案。在这方面,被认为与这个问题最相关的标准是通过听取专家意见来确定的。利用Super Decisions V 2.10,通过层次分析法(AHP)确定需求的重要顺序,将其权重作为目标规划(GP)模型中目标函数的系数。利用GAMS(通用代数建模系统)求解GP模型,决定在9个不同地点的备选仓库位置中选择提供最优结果的仓库。此外,为了看到标准权重变化的影响,还包括敏感性分析。本研究的意义在于结合AHP和GP在国防工业中根据专家意见确定仓库位置的应用。通过本研究,不仅制定了解决方案策略,而且为国防工业项目中已经签署或即将签署的仓库选址决策提供了依据。
