Jamological approach to steel production and logistics

We applied Jamological approach to steel plate production process. Jamology is the method to treats the actual complex flow problem with macroscopic view, which key tool is on ASEP model and the fundamental diagram. For abstraction of the actual plant, we applied ABC categorizing to the practical data according to the bottle neck process. Moreover, we analyzed the reason of make span variation and derived the optimal sequencing pattern by using pair gap list. We indicated effectiveness of the proposed algorithm based on a transition matrix for practical data and derived the corresponding fundamental diagram which is much different from the traffic flow case.
