Many decisions to be made in management or planning of an enterprise are optimization problems. The field of research concerned with solving them is called operations research [運籌學]. We are concerned with questions such as

  • How can we divide blocks of raw material into parts of exactly the right sizes needed for the work pieces the customer wants, with minimum wastage?
  • If a company has already several dependencies in China and wants to open a new office, in which city should that be located to maximize customer coverage and company profit?
  • How should incoming customer orders be assigned to machines for manufacturing so that all orders are completed on time and as fast as possible (also considering that an order may need to be processed by multiple machines in multiple steps)?

These few examples show that the direction borders directly to our logistics direction and topics relevant to the concepts of Industry 4.0 and Made in China 2025 [中国制造2025] as it can make production both greener and more intelligent. Our institute can provide a framework for the optimized operation in a highly automated manufacturing environment.
