The simulation is a dynamic tool forecast a system evolution and find a solution to get the desired responses.

If the system is easy to solve this kind of analisys can be done in static mode with math model;  but if the complexity increase only simulation technique can afford to get a better result and solve the problem.

​In industrial field the simulation can be used in all phases of Life Cycle Cost, expecially during flow pre-engineering phase when are defined material and information flow to get the production target.

The aims

img3The aim of any flow simulation analysis is to provide the customer all relevant results, which the management can use in order to take smarted decisions about things like flow management, investments on assets or eventual layout variations.

In general, with the simulation, engineers optimize the production, logistic and information flow, finding and overcoming process bottlenecks

Simulation Process

img4aThe simulation process is highly complex and it should be leaded by experts, as mistakes often occurs. The major steps to conduce a simulation analysis are the followings:

  • Data collection: layout, availability, production mix, principal material paths, etc.
  • The construction of a model that is able to function over time in a similar way to the system under examination
  • Conducting several experiments on the model, generating different simulation scenarios to observe the behavior of the system under different conditions
  • Analysis of the results, the enhancement of the alternative proposals and study the links between alternative inputs and different outputs of the system.

The main methods to be used in the iterative process of a simulation study

The main methods to be used in the iterative process of a simulation study are:

  • Decision on the basis of objective and quantifiable data
  • Test Type WHAT-IF
  • Assessment of Alternatives
  • Identification and Analysis of Critical Points

Benefits arising from use of simulation

img6The simulation of a production process enables measurement of the performance of a production line without the need to actually put into operation. 

This benefit can break down in an exponential manner the time and cost necessary for the design of the line and the administration of tests, not to mention that through the simulation can predict possible critical system and take precautions in advance.     

​Other principal advantages of the use of the simulation for the analysis of production systems are:

  • Accuracy of the result obtained
  • Possibility of analysis and control of the development of complex systems
  • Possibility to analyze the system in time
  • Possibility to observation "realistic" of the evolving system
  • Capacity Automatic Data Processing
