COMPUTATIONAL MODELLING OF THE PARALLEL LOGISTIC SYSTEM
COMPUTATIONAL MODELLING OF THE PARALLEL LOGISTIC SYSTEM

Summary/Abstract: The paper highlights the problem of mathematical modelling of the highly complex logistic system consisting of parallel production lines. Each production route is arranged in a series of stands equipped with manufacturing machines. It is assumed that all production lines are identical. Each production stand performs a manufacturing operation with the use of the specified tool. Tools get worn out and require either regeneration or immediate replacement. The tool subjected to regeneration can be regenerated a certain number of times only. When this number is reached, the tool must be replaced with a new one. The logistic system is controlled by a determined heuristic algorithm. The production process is optimized by means of the stated criterion respecting defined bounds. Adequate equations of state illustrate the flow of charge material. The time scaling method in order to search for the satisfactory solution with the use of the simulation method is proposed.
