Bottleneck analysis

SCORE

By innovatively formulating a bottleneck analysis problem into a bi-objective optimization one, multi-objective optimization can be effectively used as a new method for general production systems improvement. In a single optimization run, all attainable, maximum throughput levels of the system can be sought through various optimal combinations of improvement changes of the resources. Additionally, the post-optimality frequency analysis on the Pareto-optimal solutions can generate a rank order of the attributes of the resources required to achieve the target throughput levels.

Using a new definition of bottleneck in production systems, FACTS Analyzer allows the use of multi-objective optimization to answer the following important question that many production managers/engineers would ask in a daily basis:

  • Where and what are the minimum changes (lowest cost) in order to improve the overall capacity of the line?
