<p>PURPOSE:To execute efficient transportation control by the queue control logic which determines the priority and coefft. to determine the execution order of transportation for each of production stages based on the definition to determine priority order, calculates evaluation values of each of the production stages by the calculation equations to determine the execution order and sets the priority order in accordance with the descending order of the evaluation values. CONSTITUTION:A transportation control system FA for controlling the movement of transfer containers, a process control system PA for controlling the equipment for finishing raw materials or intermediate products to products and an integral control system MC for integrating these two systems and having the control logic for queue are constituted in the batch operated plant for transporting the raw materials or intermediate products to each of the production stages by using the transfer containers and finishing the raw materials or intermediate products into the products. This queue control logic determines the priority and coefft. to determine the execution order of transportation for each of the production stages based on the definition to determine the priority order, calculates the evaluation values of each of the production stages by the calculation equations to determine the execution order and sets the priority order in accordance with the descending order of the calculation values.</p> |
