This paper analyzes the capacitated lot sizing problem considering an individual machine's processing ability using a two-layer hierarchical method to minimize the sum of the dynamic inventory cost and the overtime cost. 以动态库存成本与加班惩罚费用之和为优化目标,考虑单台机器的生产能力,研究生产批量计划问题。
It is blind to conduct management without techniques, which results in lower success ratio of work over treatment, shorter free work overtime, higher fault rate, and higher cost of management. 缺乏技术的管理是盲目的,其结果是修井作业成功率低、油井免修期短、油井故障率高、管理成本升高等等。
The controversy surrounding this issue overtime has become more accentuated practically due to the lack of balance between the over riding objective of having a short time framework for a project, and at a relatively low cost without impacting heavily on the quality of work done. 因在过度强调工期与在不影响工程质量的前提下相对降低工程费用之间缺少平衡,所以围绕这一问题进行旷日持久的争论已更为人们在实践中所重视。
