A. Understanding Systems
The system is a network of procedures that are interconnected, gathered together to perform an activity or to accomplish a particular goal.
In essence the system consists of:
1. The components in the system, including
- Hardware / hardware,
- Software / software,
- Procedures / procedure,
- The human / brain-ware, and
- Information / information itself
2. serta technology functions in it are:
- Input,
- Process / process,
- Output,
- Storage / storage and
- Communication / communication.
Understanding the system according to Wikipedia is derived from the Latin system (Systema) and Greek (sustēma) is a unit consisting of components or elements are linked together to facilitate the flow of information, materials or energy. The term is often used to describe a set of entities that interact, in which a mathematical model can often be made.
Medium according to some experts understanding of the system are as follows:
- According LUDWIG VON BARTALANFY => System is a set of interlocking elements in suatuantar relationships between the elements of the environment.
- According to Anatol RAPOROT => The system is a collection of unity and the relationship to one another.
- According to L. ACKOF => System is any entity conceptually or physically yangterdiri of the parts in a state dependent on each other.
In principle, every system always consists of four elements:
- The object, which may be part of, elements, or variables. He can be physical objects, abstract, or both at once; depending on the nature of the system.
- Attribute, which determines the quality or nature of the ownership of the system and its object.
- Internal relationships among the objects in it.
- Environment, a place where the systems are
System requirements:
1. The system should be established to resolve the problem.
2. Elements of the system must have an established plan.
3. The existence of a relationship between elements of the system.
4. The basic elements of the process (the flow of information, energy and material) more
an important element of the system.
5. The purpose of the organization is more important than the destination element.
Understanding System According to the Experts
The term system is a term from the Greek "system" which means a set of parts or elements that are interconnected in order to achieve a common goal.
Understanding the system according to some experts:
1. L. James Havery
He said the system is a logical and rational procedure for designing a circuit component associated with each other with a view to function as a whole in order to achieve a predetermined goal.
2. John Mc Manama
He said the system is a conceptual structure that is composed of the functions are interconnected to work as an organic unity to achieve a desired result effectively and efficiently.
3. C.W. Churchman.
He said the system is a set of parts that are coordinated to carry out a set of goals.
4. J.C. Hinggins
He said the system is a set of interrelated parts.
5. Edgar F Huse and James L. Bowdict
He said the system is a series or circuit parts are interconnected and dependent such that the interaction and mutual influence of one part affects the whole.
