BIG DATA IN DESIGN AND MANUFACTURING
ENGINEERING
REVIEW
STRUCTURE OF THE RESEARCH PAPER
This paper introduces Big Data, its characteristics and a number of issues of Big Data in
design and manufacturing engineering. These issues include design and manufacturing data,
Big Data benefits and impacts and its applications and opportunities. Methods, technologies
and some technology progress around Big Data are presented in this study. General
challenges of Big Data and Big Data challenges in design and manufacturing engineering are
also discussed.
What is Big Data?
Extremely large data sets that may be analysed computationally to reveal patterns,
trends, and associations, especially relating to human behaviour and interactions.
Datasets whose size is beyond the ability of typical database software tools to capture,
store, manage and analyze.
Ranges from a few dozen Terabytes (TB≈1012
bytes) to multiple Petabytes (PB≈1015
bytes).

It is an optimum value-adding approach by squeezing a huge data volume for more
enhanced data flow velocity into a lesser time, and also stepping up the data variety
into more enhanced date veracity in a lesser time.
Benefits and Impacts of Big Data in Design and Manufacturing
Engineering
Defect tracking and product quality:
Perform predictive diagnostics for product/part failure
Monitor product data quality
Early detect quality problems
Better detect product defects
Provide real-time alerts based on analyzing manufacturing data
Reduces defects during manufacturing processes by tracking every detail about every
part that goes into a product
Boost quality
Improvements in supply planning:
Unlock significant value and unearth valuable insights by performing Big Data
analytics and making information transparent
Better forecast products, production and manufacturing output
Better forecast sales volumes through semantic based Big Data analytics
Improve relationship with suppliers and conduct better contract negotiations
according to collected supplier performance data
Improve decision-making and minimizes risks in supply
Improved product manufacturing processes:
Provide an infrastructure for transparency in manufacturing
Analyze sensor data from production lines, creating self-regulating processes that cut
waste, avoid costly (and sometimes dangerous) human interventions and ultimately
lift output
Better monitor and control manufacturing processes by tracking every detail about
every part and procedure, better information visibility and Big Data analytics for
data in motion
Perform predictive manufacturing and optimize manufacturing processes
Better simulate and test new manufacturing processes
4. 4
Driven efficiency across the extended enterprise:
Increase the efficiency of the manufacturing processes
Increase energy efficiency
Enable effective and consistent collaboration through integrating datasets from
multiple systems and divisions
Facilitate innovative design for manufacturing and integration of CAD/CAE/CAM;
reduce unnecessary iterations in product development cycles; and finally reduce
production and development costs
Offer further opportunities to accelerate product development; increase product
innovation and development of next-generation products
Improved service:
Determine what manufacturing parameters most influence customer satisfaction
Develop new products and make products better match customers’ needs through
sentiment analysis and recommendation systems for Big Data
Enable mass-customization in manufacturing
Better correlate manufacturing and business performance information together
Reduce warranty costs through warranty analysis based on Big Data analytics
Better perform remote intelligent services

Challenges of Big Data
Difficulty in data management activities such as query and storage efficiently.
Challenges in extracting the meaning of the information from massive volumes of
unstructured data.
Difficulty in collecting and integrating data with scalability from distributed locations
because of the variety of disparate data sources and the sheer volume
Data are susceptible to errors and noises.
Ensuring privacy and information security.
Conclusion
Big data frame work
Big data analytics is the process of examining large data sets containing a variety of data
types i.e., big data to uncover hidden patterns, unknown correlations, market trends, customer
preferences and other useful business information. The analytical findings can lead to more
effective marketing, new revenue opportunities, better customer service, improved
operational efficiency, competitive advantages over rival organizations and other business
benefits.

Big Data is large in volume, velocity, variety, value, variability and veracity. Big Data helps
integrate various types of datasets in design and manufacturing engineering; uncover hidden
correlation patterns through analytics; improve design and production processes; and create
more values. Mining Big Data helps improve design in quality, time, costs and mass-
customization. Big Data also offers greatest benefits for manufacturing engineering such as
detecting product defects, boosting quality and improving supply planning, etc. It has had a
lot of applications or great opportunities in design and manufacturing engineering. Generally,
Big Data has challenges such as data capture, date integration, data visualization, extracting
values from all of heterogeneous data and privacy and information security, etc. Big Data
means more information, but it also means more false information. Its focus is on
correlations, not causality.
Data is no longer simply numbers in a database. Text, audio and video files can also provide
valuable insight; the right tools can even recognize specific patterns based on predefined
criteria. Big data can contribute a lot to the production and operations management of any
industry.
It is estimated that by 2020 there could be four times more digital data than all the grains of
sand on earth. The world is one big data problem. Without big data analytics companies are
blind and deaf, wandering out onto the web like deer on a freeway.
Data is the new science. Big data holds the answers. Are you asking the right questions ?
