Material control system
First Claim
1. A material control system (MCS) to select an optimum transport route by calculating a prospective transport time between a source node and a destination node, comprising:
- a transport order manager to receive and manage layout information, and real-time job information of a load and a waiting job number of a storehouse according to respective unit links;
an optimum route generating part to calculate the prospective transport time by receiving the layout information and the real-time job information in a predetermined period of time from the transport order manager and by modeling the information, and to select a transport route having a minimum prospective transport time as the optimum transport route.

Abstract
A material control system (MCS) to select an optimum transport route by calculating a prospective transport time between a source node and a destination node includes a transport order manager to receive and manage layout information, and real-time job information of a load and a waiting job number of a storehouse according to respective unit links. The MCS also includes an optimum route generating part to calculate the prospective transport time by receiving the layout information and the real-time job information in a predetermined period of time from the transport order manager and by modeling the information. The optimum route generating part also selects a transport route having a minimum prospective transport time as the optimum transport route. Thus, a transport flow of production lines may be balanced, and interruption between transport vehicles may be minimized, thereby enabling overall transport efficiency to be maximized.

12. A method of controlling a material control system to select an optimum transport route between a source node and a destination node, the method comprising:
-
receiving and managing real layout information and real-time job information of a load and a waiting job number of a storehouse according to respective links;
creating a data structure based on the real layout information and the real-time job information, and updating the data structure by receiving the real layout information and the real-time job information periodically;
creating a route search structure based on a route search demand;
calculating a prospective transport time according to the respective links within the route search structure; and
selecting a transport route having a minimum prospective transport time of the respective links within the route search structure to reach the destination node from the source node, as the optimum transport route. - View Dependent Claims (13, 14, 15)
