Introduction
![Page 7: Dynamic Simulation of Grain Storage Facilities · Work Experience West Paraná State University – UNIOESTE Auxiliary Professor, 1986 -1990Auxiliary Professor Assistant Professor,](https://reader031.vdocuments.net/reader031/viewer/2022011916/5fe0bcde949182722438ffd1/html5/thumbnails/7.jpg)
What is simulation?
Simulation is the operation of a developed model, which main purposes are:
(a) to guide the decision process,
(b) to carry on analyses and evaluations of systems, and
(c) to define solutions for improving a system performance.
(Monsef 1997, Neelamkavil 1987, Maria 1997).

What is System?(According to Researches Operations Fundaments)
System is “any sorted group of objects that perform together or inter-work in other to reach one logical goal”
(Schmidt and Taylor 1970).
![Page 9: Dynamic Simulation of Grain Storage Facilities · Work Experience West Paraná State University – UNIOESTE Auxiliary Professor, 1986 -1990Auxiliary Professor Assistant Professor,](https://reader031.vdocuments.net/reader031/viewer/2022011916/5fe0bcde949182722438ffd1/html5/thumbnails/9.jpg)
Grain Storage Facility is a systemdesigned for the appropriate receiving, cleaning, drying, storing and dispatching of grains and legumes (Flores 1988).
What is Grain Facility System?

What is model?(According to Researches Operations Fundaments)
Model may be defined as a representation of a system, which aims to describe system elements and their interrelationships.
(Neelamkavil 1987, Maria 1997).
