Supply chains are networks of entities that include suppliers of raw material, production manufacturing units who convert the material into products, warehouses that store, and distribution centres that cover the flows of products from suppliers to retailers and customers. Modern industries strive to have the most optimized supply chain because it usually translates to a better performance for the company. Supply chain optimization implies optimization of three types of activities: strategic design, tactical planning and operational execution, which are distinguished by managerial level, time horizon and uncertainty in the decision environment. Strategic design decisions establish and modify the resources available to the enterprise, such as manufacturing plants, logistics networks and warehouses. Tactical planning decisions imply developing timetables for planned production, maintenance, transportation, workforce, sales and the inventory levels that will optimally match high-quality production to sales. Operational control involves the detailed execution of short-term schedules by all parts of the organization, in such a way as to achieve the profit and performance goals established by the plans. At each level, there are many kinds of uncertainties that create significant challenges for optimization. These uncertainties include machine failures, accidents, attacks, and fluctuations of demands, raw materials, costs and prices. Our research program is part of a continuing effort aimed at developing effective decision-support tools to tackle important optimization problems encountered at the strategic design, tactical planning and operational execution of supply chains. The proposed research program will focus on the following projects: At the strategic level - Design of failure-prone manufacturing networks used in high-volume production. - Design of robust distribution networks under random supply and demand. - Design of maintenance logistics networks.  At the tactical level - Tactical planning in maintenance logistics networks. - Integrated planning of production, maintenance and quality. At the operational level - Reactive planning under uncertainties in demand, supply quantities, raw material costs, machine failures, and price fluctuations. Efforts will be made to ensure the transfer of the research program results to industry. Considering the socio-economic importance of supply chains and the challenging scientific and practical problems encountered when dealing with uncertainties, the impact of this new research program could prove to be extremely significant.

供应链是实体网络，包括原材料供应商，将材料转化为产品的生产制造单位，存储仓库和涵盖从供应商到零售商和客户的产品流的配送中心。现代工业努力拥有最优化的供应链，因为它通常转化为公司更好的业绩。供应链优化意味着对战略设计、战术规划和运营执行三种活动的优化，这三种活动因管理水平、时间范围和决策环境的不确定性而有所区别。战略设计决策建立和修改企业可用的资源，例如制造工厂、物流网络和仓库。战术计划决策意味着制定计划生产、维护、运输、劳动力、销售和库存水平的时间表，以最佳地匹配高质量的生产和销售。运营控制包括组织各部门详细执行短期计划，以实现计划所确定的利润和绩效目标。在每个级别上，都存在许多不确定性，这些不确定性给优化带来了重大挑战。这些不确定性包括机器故障、事故、攻击以及需求、原材料、成本和价格的波动。我们的研究项目是持续努力的一部分，旨在开发有效的决策支持工具，以解决供应链战略设计、战术规划和运营执行中遇到的重要优化问题。拟议的研究计划将侧重于以下项目：在战略层面-设计用于大批量生产的易故障制造网络。-随机供需条件下的稳健配电网络设计。-维修物流网络设计。在战术层面——维修后勤网络中的战术规划。-生产、维修和质量的综合计划。在操作层面——在需求、供给量、原材料成本、机器故障和价格波动等不确定因素下的反应性计划。努力确保研究项目成果向产业转化。考虑到供应链的社会经济重要性，以及在处理不确定性时遇到的具有挑战性的科学和实际问题，这项新研究计划的影响可能被证明是极其重要的。
