Haier's logistics informatization is very good. According to the requirements of JIT theory, it can calculate the latest demand time of materials, the latest start time of processes, and the timely distribution of production equipment and human resources, and summarize all the resources currently needed at the first time to obtain high-quality and low-cost parts around the world.

Although the number of "JIT" is small, it is not a "small number" if it can summarize all the resources that the enterprise needs at present, so it will consider large-scale, so that every purchase will not cause waste and save a lot of resources.

But also realize the perfect combination of JIT and MRPII in mass customization environment.

The environment of each enterprise is different, so it is impossible to produce according to one mode. If we can find the cut-off point between JIT and unified procurement, it will certainly be of great benefit to enterprises.
