Conclusion

Production - The creation

of goods using land, labor,

capital, entrepreneurship

and knowledge .

Production scheduling technique - It is the technique used in allocation of resources and the sequencing of tasks to produce goods and services. Production scheduling specifies the time each job starts and completes on each machine, as well as any additional resources needed.

Manufacturing industry refers to any business that transforms raw materials into finished or semi-finished goods using machines, tools and labor.

The Manufacturing technique

Final phase in the process of manufacturing an automobile. The components supplied by more than 4,000 outside

suppliers. Materials are brought together for assembly, usually by truck

or railroad. Parts for chassis are delivered to one area while those that

will comprise the body are unloaded at another.

Chassis Firstly constructed from the ground up (and out), ie The

frame forms the base on which the body rests. The frame is placed on the assembly line. From here the automobile frame moves to component

assembly areas

Heavy component parts. Robots implemented rather than

humans. Robots weld the floor pan pieces

together Assist workers

Robots at Work in Car Assembly

Paint The shell of the vehicle passes through a

brightly lit white room Inspectors using cloths soaked in hi-light oil. This oil allows inspectors to see any defects

in the sheet metal body panels. the assembly conveyor carries it through a

cleaning station. A drying booth and then through an

undercoat dip—an electrostatically charged bath of undercoat paint (called the E-coat)

After the E-coat bath, the shell is again dried in a booth.

Spray-painted by robots that have been programmed.

Covered with a base coat of color paint and a clear top coat.

The conveyor transfers the bodies through baking ovens.

Where the paint is cured at temperatures exceeding 275 degrees Fahrenheit (135 degrees Celsius).

Mate The chassis assembly conveyor and the body shell

conveyor meet at this stage Robotically lifted from its conveyor fixtures and placed

onto the car frame. Bolt the car body to the frame. Proceeds down the line to receive final trim

components, battery, tires, anti-freeze, and gasoline. The vehicle can now be started. From here it is driven to a checkpoint off the line,

usually located near the end of the line. Analyze and repair all problems. Given a price label and driven to a staging lot.

ConclusionThe growth of automobile use and the increasing resistance to road building have made our highway systems both congested and obsolete. But new electronic vehicle technologies that permit cars to navigate around the congestion and even drive themselves may soon become possible. Turning over the operation of our automobiles to computers would mean they would gather information from the roadway about congestion and find the fastest route to their instructed destination, thus making better use of limited highway space. The advent of the electric car will come because of a rare convergence of circumstance and ability. Growing intolerance for pollution combined with extraordinary technological advancements will change the global transportation paradigm that will carry us into the future generation.
