Is the scheduling task context-dependent? A survey investigating the presence of constraints in different manufacturing contexts
通过对50家公司的调查，研究实际生产调度中的约束条件是否因制造环境不同而存在差异，发现部分约束具有上下文依赖性。
Most studies regarding real scheduling constraints only consider the constraints related to the specific manufacturing environment studied, limiting the possibility of drawing general conclusions. A survey of 50 companies was conducted in order to discover which constraints were present and what their relationship was with the scheduling context. This paper investigates which practical scheduling constraints are present in the manufacturing industry and whether the scheduling task is context-dependent. Results of this study show that some practical production constraints are context-dependent.
