DESIGN SYSTEM AND SERVICE

WHAT IS SYSTEM ??

System is a collection of elements or components that are organized for a common purpose. The word sometimes describe the organization or plan itself and sometimes describe the part in the system.

All the nature and the universe can be said to be a system. We've coined a word, ecosystem, for the system on earth that effect the life system. The term can be very useful because so many things can be describe as system. It can also be very usefulness when a more specific term in needed.

 There are four types of system depending on whether the parts and the whole can display choose, and therefore, be purposeful.

• MECHANISTIC 
• ANIMATE
• SOCIAL
• ECOLOGICAL

MECHANISTIC

Mechanistic system and their parts have no purpose of their own, but their essential parts make possible the functioning of the whole. All mechanisms are mechanistic systems and also the plants. Clock are common example of such system, they operate with regularity dictated by their internal structure and the causal laws of nature. Neither the whole nor the parts of a clock display choice, but they have function. Similarly, an automobile is a mechanical system that has no purpose of it's own but serves it's driver's and passengers' purpose.

Mechanistic have two system either it is close or open system, close if their behavior is unaffected by and external conditions or event meanwhile the open if they are so affected. The universe was conceptualized by Newton as a close mechanical system, with no environment-like a hermetically sealed clock. On the other hand, the planet earth is seen as an open system, one whose motion is influenced by other bodies in the solar system.

ANIMATE

Animate system are living system. These are conceptualized as purpose system whose parts have no purpose of their own. The principle purpose of such system is survival. A person's lungs have no purpose of their own, but they function to enable a person to extract oxygen from the environment so as to survive. Animate system these interaction is essential for understanding their properties and behavior.

SOCIAL

The system that have :

1. Purpose of their own
2. Consist of parts at least some which are animate, hence have purpose of their own
3. Are part of one or more larger system that may have purpose of their own and that may contain other social system.

The example of the social system is a local government viewed as a social system part of a state government, which is also a social system. This in turn, is part of a national government. Social system can be and usually are nested. 

ECOLOGICAL 

Ecological system serve the purpose of their animate and social parts, and provide necessary inputs to these and open deterministic system. They also provide a receptacle for their waste as well as their useful products. Such service and support is their function. An ecological system can be effected mechanistically by the mechanical or purposeful behavior of its parts. For example, the purposeful use by people of fluro-carbons as a propellant and the emissions of power plants effect the ozone layer mechanistically.
