摘要： PROBLEM TO BE SOLVED: To raise working efficiency to maximum and automatically control a tank charging work by avoiding conflict between a plurality of tank charging works, computing a tank charging work beginning time, a completing time, and a tank charging quantity practicable for making the working efficiency to maximum under the restricted condition, and controlling receipt, delivery, and carrying facilities. SOLUTION: Imaginarily regarding that a system for blast furnace and a system for sintering ate independent of each other, a mixed integer programming is used to dissolve conflict. Respective tank charging plans are edited in order of the beginning time of the tank charging work at every original device and system, and output to an interface file outputting to a process computer setting control processing 110. Further, the stting control information is transmitted to a subordinary controller for controlling jobfield facility/device by the setting control processing 110, and a moving machine group and a belt conveyor group are automatically controlled by the time, the order, the using facility, the brand of material, and the tank charging quantity in accordance with the tank charging work plan. The computed result of the tank charging work planning function is presented to an operator in a CRT 119 through an operator input/output processing 107.

摘要： PROBLEM TO BE SOLVED: To improve material transport efficiency by changing a transporting time and assignment of material to dissolve conflict when existence of conflict in the same decided transporting passage is checked and conflict exists, concerning a material transporting work of the same time to different material storage tanks of two or more. SOLUTION: From the present storing level Ln of each material tank, the upper limit value L2 and the lower limit value L1 of a tank storing lower limit region controlled by an operator, and the present tank material using speed, the upper limit value arrival time T2 and the lower limit value arrival time T1 are obtained. Based on the lower limit value L1 and the upper limit value L2, time belts for charging tank T2-T1 having select width on a tank charging beginning time are decided. Based on arrangement of material transporting devices of a transporting facility, the present using condition of the facility, information of material yards, the troubled condition of the facility, reparing schedule of the facility in future, a computer groups the material tanks, conflict in the time belt of charging tank is dissolved at the group unit, and the order of tank charging works, that is, material feed times and transporting passages for use to the respective material tanks are decided.
