在这个由两部分组成的系列论文中，建立了半连续过程的生产计划和调度模型，该过程假设由位于不同地理位置的几个设施组成，每个设施可能包含多个平行单元。所开发的模型本质上是确定性的，并且被表示为混合整数线性规划(MIP)。第一部分涉及多阶段中期计划模型，其中采购考虑很重要，因为产品可以在几个设施中生产，通常在不同的大陆上。这类模型的主要目标是将资产优化配置到生产任务中，以满足全球市场在更大范围内波动的需求。根据涉及收益最大化和生产、库存和运输成本最小化的目标函数来评估计划绩效。在这些类型的模型中，生产活动的实际时间和顺序并不是确定的…
In this two-part series of papers, production planning and scheduling models are developed for the case of semicontinuous processes which are assumed to comprise several facilities in distinct geographical locations, each potentially containing multiple parallel units. The models developed are deterministic in nature and are formulated as mixed-integer linear programs (MIP's). Part 1 deals with multiperiod midterm planning models where sourcing considerations are important, given that products can be manufactured at several facilities, often on different continents. Optimal allocation of assets to production tasks in order to satisfy the fluctuating demands of the global marketplace over an extended horizon is the main goal in this kind of model. Plan performance is assessed relative to an objective function involving maximization of earnings and minimization of production, inventory, and transportation costs. In these types of models, the actual timing and sequencing of production campaigns is not determ...
