Supply Chain Management (SCM), by way of one of the critical issues in the managerial aspect, plays a significant role in tackling humanitarian problems and difficulties. Due to some limitations (e.g., production capacity and storage capacity) and desires (e.g., cost reduction and rising revenues), supply chain managers always seek the best response to the amount and type of communication between different SCM levels. In the upcoming research, a Pharmaceutical Supply Chain (PSC) with three objective functions is developed, aiming to simultaneously minimize total costs, unfulfilled demands, and reduce the waiting time at the factory entrance. In the forthcoming research, the subject literature and research in the PSC modeling and problem-solving are discussed. A nonlinear programming model is then proposed in line with the previous research to solve the existing shortcomings. Also, multi-objective decision-making methods are used to match the conflicting objectives of the model simultaneously. Then, GAMS commercial software is used to solve the problem of different sizes. Finally, the wide sensitivity analysis and evaluation of the results are discussed, and future development suggestions are presented.

考虑工厂药品拥塞的药品供应链多功能三目标数学模型

供应链管理(SCM)作为管理方面的关键问题之一,在解决人道主义问题和困难方面发挥着重要作用。由于一些限制(例如,生产能力和存储能力)和期望(例如,降低成本和增加收入),供应链经理总是寻求对不同 SCM 级别之间的通信数量和类型的最佳响应。在即将进行的研究中,开发了具有三个目标函数的药品供应链 (PSC),旨在同时最小化总成本、未满足的需求并减少工厂入口处的等待时间。在即将进行的研究中,将讨论 PSC 建模和问题解决方面的主题文献和研究。然后结合前人的研究提出非线性规划模型来解决存在的不足。此外,多目标决策方法用于同时匹配模型的冲突目标。然后,使用 GAMS 商业软件来解决不同大小的问题。最后,对结果的广泛敏感性分析和评价进行了讨论,并提出了未来的发展建议。
