Definition of Industrial Engineering

Industrial engineering is a branch of engineering that concerns the development, improvement, implementation and evaluation of integrated systems of people, money, knowledge, information, equipment, energy, material and process.

Industrial engineering draws upon the principles and methods of engineering analysis and synthesis, as well as mathematical, physical and social sciences together with the principles and methods of engineering analysis and design to specify, predict and evaluate the results to be obtained from such systems.

What does an Industrial Engineer do?

Industrial Engineers figure out how to do things better.

They engineer processes and systems to improve quality and productivity. They work to eliminate waste of time, money, materials and various resources.

While engineers from other disciplines apply their skills to very specific areas, the Industrial Engineer has the opportunity to work in a variety of businesses.

What does an Industrial Engineer do? (Cont.)

The most distinctive aspect of ISE training is the flexibility and versatility it can offer. Whether it is improving product quality, planning manufacturing resources or designing logistics distribution channels, all share the common objective of cost-cutting, increasing efficiencies and ultimately driving up the profit margins. That is why more and more companies are hiring Industrial Engineers and thenpromoting them into management positions.

What does an Industrial Engineer do? (Cont.) Industrial Engineers are often required to solve large and

complex real-world problems.

To accomplish this, it is necessary to adopt a holistic and integrated approach to problem-solving that requires a unique blend of scientific analytical methods and creativity.

They are synonymous with a systems integrator, i.e. a ‘big-picture thinker'. They also form the vital link between management and engineering where scientific methods are used heavily in making managerial decisions.

What is Unique about Industrial Engineering? The domain knowledge of Industrial Engineering (IE) is derived

from combinations of engineering, mathematics, statistics, computing and social sciences.

The IE discipline calls for the adoption of a holistic view in resolving problems encountered and developing opportunities presented, coupled with a strong emphasis on efficiency and productivity improvement.

What is Unique about Industrial Engineering? (Cont.)

Its application can be found in a wide range of areas. Some examples are:

Manufacturing industry: Ensuring that the equipment, manpower and other resources in the manufacturing process are integrated in such a manner so as to maintain efficient operation and for continuous improvement.

Logistics industry: Management of supply chain systems (e.g. manufacturing facilities, transportation carriers, distribution hubs, and retailers) through integration and optimization with the goal of fulfilling customer orders in the most cost effective way.

What is Unique about Industrial Engineering? (Cont.)

Service industry: Provision of consultancies in areas related toorganizational effectiveness, service quality, information systems, project management, banking service strategy, etc.

Defence industry: Tools to support the management of military assets and military operations in an effective and efficient manner.

Jobs and functions performed by Industrial Engineers On demand

Investigate problems relating to component quality or difficulties in meeting design and method constraints.

Investigate problems with the performance of processes or machines.

Implement design changes at the appropriate times.

Jobs and functions performed by Industrial Engineers (Cont.)

Specifically per product (short term)

Analysis of the complete product design to determine the way the whole process should be split into steps, or operations, and whether to produce sub-assemblies at certain points in the whole process. This requiresknowledge of the facilities available in-house or at sub-contractors.

Specification of the method to be used to manufacture or assemble the product(s) at each operation. This includes the machines, tooling, jigs and fixtures and safety equipment, which may have to be designed and built. Notice may need to be taken of any quality procedures and constraints, such as ISO9000. This requires knowledge of health and safety responsibilities and quality policies. This may also involve the creation of programs for any automated machinery.

Jobs and functions performed by Industrial Engineers (Cont.)Specifically per product (short term)

Measurement or calculation of the time required to perform the specified method, taking account of the skills of the operator. This is used to cost the operation performed, to allow balancing of assembly or machining flow lines or the assessment of the manufacturing capacity required. This technique is known as work study or time and motion studies. These times are also used in value analysis.

Specification of the storage, handling and transportation methods and equipment required for components and finished product, and at any intermediate stages throughout the whole process. This should eliminate the possibility for damage and minimize the space required.

Jobs and functions performed by Industrial Engineers (Cont.)

Specifically per process (medium term)

Determine the maintenance plan for that process.

Assess the range of products passing through the process, then investigate the opportunities for process improvement through a reconfiguration of the existing facilities or through the purchase of more efficient equipment. This may also include the out-sourcing of that process. This requires knowledge of design techniques and of investment analysis.

Review the individual products passing through the process to identify improvements that can be made by redesign of the product, to reduce (or eliminate) the cost that process adds, or to standardize the components, tooling or methods used.

Jobs and functions performed by Industrial Engineers (Cont.)

Generically (long term)

Analyze the flow of products through the facilities of the factory to assess the overall efficiency, and whether the most important products have priority for the most efficient process or machine. This means maximizing throughout for the most profitable products. This requires knowledge of statistical analysis and queuing theory, and of facilities positional layout.

Training of new workers in the techniques required to operate the machines or assembly processes.

Project planning to achieve timely introduction of new products and processes or changes to them.

Generally, a good understanding of the structure and operation of the wider elements of the Company, such as sales, purchasing, planning, design and finance; including good communication skills. Modern practice also requires good skills in participation in multi-disciplinary teams.
