A System Theory for Production Lines: Improvability

本研究涉及应用系统理论的严格数学分析，通过更好地配置资源来提高生产线的产出率。这是解决“瓶颈”问题的一种创新方法。研究人员开发了一种可改进性理论，如果在制品或劳动力等有限资源可以重新分配，从而提高绩效指数（通常是生产率），那么在约束条件下，生产系统被认为是可改进的。在这里，我们寻求的是改进，而不是最优性，因为由于生产系统极其复杂的数学性质，通常不可能确定最优性。该研究还将调查无约束的可改进性，即确定以最强方式阻碍系统性能的机器，设备或装配站，即瓶颈。研究的方法是基于健全的数学原理，这导致了可用的操作规则的“车间”地板。研究人员有着良好的行业联系，理论成果在真实的产业环境中不断得到评价。

9531694 Meerkov This research concerns the application of rigorous mathematical analysis from systems theory to improve output rate of production lines by better allocation of resources. It is an innovative approach to the "bottleneck " problem. The researchers have developed a theory of improvability, where a production system is considered improvable under constraints if limited resources such as work -in-process or workforce can be redistributed so that a performance index (usually production rate) can be increased. Here, improvement, rather than optimality, is looked for, since it is often impossible to determine optimality due to the extremely complex mathematical nature of production systems. The research will also investigate unconstrained improvability, namely determining the machine, device, or assembly station that impedes the systems performance in the strongest manner, i.e., the bottleneck. The approach of the research is based on sound mathematical principles which result in usable operating rules for the "shop" floor. The researchers have excellent industry ties, and the theoretical results are constantly evaluated in real industrial environments.
