Everything is becoming
INSTRUMENTED
We now have the ability to measure, sense and see the exact condition of practically everything.
INTERCONNECTED
People, systems and objects can communicate
and interact with each other in entirely new
ways.
INTELLIGENT
We can respond to changes quickly and accurately, and get better results
by predicting and optimizing
for future events.

Analytics & Optimization

Volume of Digital DataEvery day, 15 petabytes of new information are being generated. This is 8x more than the information in all U.S. libraries.
By 2010, the codified information base of the world is expected to double every 11 hours.
Massive amounts of data being captured on natural and man-made engineered structures, processes and systems
Importance of Decision Making70% of executives believe that poor decision making has had a degrading impact on their companies’ performance
Only 9% of CFOs believe they excel at interpreting data for senior management
Analytics, modeling, and visualization of these data can help to run our systems more effectively

What could happen … ?
What if these trends continue?
What actions are needed?
How many, how often, where?

Hospitals are Complex Systems
Hospitals
“Modern medicine is one of those incredible works of reason: an elaborate system of specialized knowledge, technical procedures, and rules of behavior.”
– Paul Starr, author of The Social Transformation of American Medicine

OR techniques -- model and analyze new processes
RFID tags to track IV pumps – IV pumps – nurses typically spent over an hour each day looking for equipment –
resulted in pumps being hoarded• No being properly cleaned • Not certified to be pumping the correct amounts
– Changed to tagging each pump with an RFID to track location. – Twice daily equipment census and pick up unused pumps collected from central
locations
Improve Asset Utilization– Reduce over-buying, lost assets
Workflow Optimization– Match equipment/people to need
Results– Reduce time staff spends looking for missing devices– Pumps cleaned and certified to be pumping the correct amounts– Planned purchase of $0.5M of new pumps – not necessary

OR -- city planning and management using geographical data
DC Water & Sewer Authority -- Automated scheduling in a user selected zone of the city
Goal: •Number of Crews = 2•Shifts: 1 day shift per crew•Objective: Assign as many WO’s as possible to each crew, while maximizing the sum of the priority of the WO’s while meeting constraints of shift duration, lunch break & travel time.

Statistical Models -- city operations using historical data
Buildings: Reduce energy use and reduce greenhouse gas emissions
1,400 K-12 Public School Buildings in New York City 150 million sq ft – Joint project w. CUNY
– Static Data (5 years energy consumption, building characteristics, weather)– Statistical analysis, monitoring, simulation, optimization of energy use, GHG
emissions and retrofit planning with budget constraints
• Technical Challenges– Processing large volumes of historical data from various sources– Developing physics-based models and statistical models for energy
consumption– Simulation of energy demand, energy supply, and building operations to
reduce energy consumption, cost and GHG emissions
Results for March 2011– Martin Luther King Junior High School reduced its electricity consumption by
35.1% and 216,061 pounds of CO2 – The top 10 winning schools collectively saved 327,003 pounds of CO2 and
average reduction of 16% in electricity consumption

Water -- In the last 100 years global water usage has increased at twice the rate of population growth
Produces table grape, pepper, stone fruit and citrus varieties on 12,000 acres in California
•Analyzed different irrigation systems (incl. newer drip systems) impact on crop yields -- decreased water usage by 8.5% since 2006
•Better matching of farming equipment to specific harvesting tasks -- decreased fuel consumption by 20% since 2006

Monitoring and data collection
Natural Water System Management for Galway Bay (Ireland)
Marine research infrastructure of sensors and computational technology interconnected across Galway Bay collecting and distributing information on:
– coastal conditions– pollution levels– marine life
Streaming real-time information to allow better decision-support related to:
– Weather threats– Pollution alerts– Algal bloom prediction– Rogue waves, etc
The monitoring services, delivered via the web and other devices – used for tourism, fishing, aquaculture and environment

Dynamic Real-time Model for Galway Bay
Nat’l U of Ireland Galway and IBM collaboration
Develop model of the water quality of a bay based on the hydro-dynamics of chemical diffusion. Sensors measuring the speed at the water surface will gather data and special streaming software will be used to continuously collect and add new data to recalibrate the model and its predictions.
Two goals: 1. proof of concept for building -- a real-time continuous assimilation system (computer system + software) to model situations where real-time data + a model (e.g., traffic, smoke, fire, ...) are important; and 2. the science will inform analysis of the ecological impact of the release of waste water from the County of Donagal waste water treatment plant into its estuary.

Unstructured data / Natural language
Much of our smart world is built using highly structured dataBut a large portion of information is unstructured
Much is based on natural language -- highly contextual and full of
ambiguity.
The sheer mass of these unstructured data Difficult for unassisted humans to assimilate
Beginning to explore what computers can do to assist

Watson
Human Language
• Ambiguous, contextual, imprecise, and implicit• Contains slang, riddles, idioms, abbreviations, acronyms, …• Seemingly infinite number of ways to express the same meaning
