General principles of simulation

The optimal model of production and transportation system largely achieves the main goal of logistics, there is a reduction of the production cycle, based on minimizing inventory and eliminating intermediate storage buffer devices, increasing the speed of material flow and delivery of technology "just in time."

Essential feature of the classification of different models of logistics systems is the method of describing the state of the object. Depending on this feature models are divided into the following classes:

  • Simulation;
  • Analytical;
  • Statistics;
  • Network;
  • Matrix.

Simulation models are guided by simulation using computers.

Analytical models are constructed using classical mathematical methods, they include differential equations, theory of inventory management, probability theory, queuing theory, and others.

Mathematical models that describe the state of production facilities shall meet the requirements of the adequacy of the objects studied, adaptability, systematic approach, dynamics and possibilities of their implementation on a computer.

However, analytical models also have their advantages. They are characterized by a greater degree of generalization and the possibility of reuse.
