Optimization, Trade-offs, Quality Control

Optimization

Optimize means to make best possible use of something.If
you optimize your home storage capacity,you clean and
organize your closets and drawers to fit most in.

Optimization, Trade-offs, Quality Control

Optimization

• Optimization is a process or methodology of designing or

making a product, process, or system to the point at
which it is the most fully functional, effective, or as near
perfection as possible.

Optimization, Trade-offs, Quality Control

Optimization

Optimization is used for a specific design purpose to
enhance or to make small gains in desirable
characteristics.

Optimization, Trade-offs, Quality Control

Optimization

• One of the simplest definitions for optimization is “doing

the most with the least.

• The process of finding the most effective or favorable

value or condition.

Optimization, Trade-offs, Quality Control

Optimization

The purpose of optimization is to achieve the “best” design
relative to a set of prioritized criteria or constraints. These
include maximizing factors such as productivity, strength,
reliability, longevity, efficiency, and utilization.

Optimization

• The development of the wheel represents a good

example of the application of optimization.

• The entire process of creating should include optimization

— from the initial idea to the final product or system.

Trade-off

A trade-off is a situation where you make a compromise
between two things, or where you exchange all or parts of
one things to another.For example,you might take a day off
to go to the concert,while losing a day’s wagesass the cost
for that opportunity.

Trade-off

• Trade-off involves a choice or exchange for one quality

over another.

• For example, the decision to favor the best material

regardless of weight in order to achieve maximum
strength may require a designer to make a trade-off of
costs.

Trade-off

• In order to maintain established requirements, trade-offs

are made in order to meet the characteristics of an
optimum design.

Quality Control

Quality control is the system of checks throughout the
manufacturing process to make sure that each step is
completed to a high standard.

Quality Control

• Quality control is a planned process to ensure that a

product, service, or system meets established criteria.

Optimization, Trade-offs, Quality Control

Quality Control

• Quality control is concerned with how well a product,

service, or system conforms to specifications and
tolerances required by the design.

Optimization, Trade-offs, Quality Control

•For example, a set of rigorous
international standards (ISO
9000) has been established to
help companies systematically
increase the quality of their
products and operations.

•ISO 9000 standards are a
collection of international
standards for application in all
types of organizations.

•It is one of the most widely used
quality standards in the world.

Quality Control

•ISO 9000 is a family of standards for quality management systems.

•ISO 9000 is maintained by ISO, the International Organization for
Standardization and is administered by accreditation and certification
bodies.

•For a manufacturer, some of the requirements in ISO 9001 (which is one of
the standards in the ISO 9000 family) would include:

•a set of procedures that cover all key processes in the business;

•monitoring manufacturing processes to ensure they are producing quality
product;

•keeping proper records;

•checking outgoing product for defects, with appropriate corrective action
where necessary; and

•regularly reviewing individual processes and the quality system itself for
effectiveness.

•facilitate continual improvement
