We propose a systematic approach for generating alternative production schedules to address two challenges in implementing optimization‐based scheduling techniques in industrial settings: (a) the limited scope of the scheduling models due to modeling simplifications, and (b) the consideration of shop‐floor nervousness. We first introduce metrics to quantify specific characteristics of a schedule (e.g., number of batches and degree of nervousness). Next, we favor, at different degrees, such characteristics in each alternative schedule, by penalizing the metrics in the objective function. Through illustrative instances, we show that multiple alternative schedules, including schedules with desired properties can readily be generated.

系统生成替代生产计划

我们提出了一种用于生成替代生产计划的系统方法，以解决在工业环境中实施基于优化的计划技术的两个挑战：（a）由于建模简化而导致的计划模型范围有限，以及（b）考虑车间紧张。我们首先引入指标以量化计划的特定特征（例如，批次数量和紧张程度）。接下来，我们通过惩罚目标函数中的指标，在​​不同程度上支持每个替代进度中的此类特征。通过说明性实例，我们表明可以轻松生成多个替代计划，包括具有所需属性的计划。
