Areas of Expertise/Interest
Cognitive Analytics & Internet of Things (IoT):
IoT enables an unprecedent real-time access to data from distributed assets and the ability to trigger actions based on inferred condition of the asset or the overall (eco)-system. The two fundamental challenges are the ability to (i) contextualize the data streams into a meaningful semantic model, and (ii) analyze the data to learn interesting patterns that merit specific actions.
My current focus is to build solutions for heavy industries (heavy equipment manufacturers, production plants, connected devices etc) leveraging artificial intelligence, machine learning and knowledge representation. The first part of this effort is to understand, learn and build domain specific semantics that provide the lens needed to organize and contextualize the data streams. This effort borrows from AI (text analysis, knowledge engineering and representation) to (automatically) build domain semantic models. The next aspect is the use of machine learning techniques to learn from historical data (at the asset or system level) to understand the behavior and orchestration of assets - both in terms of normal and anomalous behavior. And finally learn from data what actions are effective under which conditions to iprove asset and system behavior and outcomes. Challenges addressed are big data analytics and machine learning targeted for sensor data.

Condition based Asset Management (CbAM)
There are 2 components for CBAM:
- Use of Static Data (log data)to create failure models, survival models and association rules - these are then used to create an optimal maintenance plan. This plan generate work orders that go into a work order management (system such as MAXIMO). On a weekly basis, the work orders are used to create a schedule for crew based on the location and priority of the work orders. This is the normal flow of things
- use of Data in Motion to detect anomalies detection (near real time) monitoring data to do anomaly detection - and generate work orders (for inspection or repair) that are loaded into work order management system (e.g. MAXIMO) with appropriate priorities.
- Analytics-driven asset management
- Learning dynamic temporal graphs for oil-production equipment monitoring system
With the advent of the Smart Grid, the infrastructure for energy supply generation and transmission is experiencing a transition from the current centralized system to a decentralized one. The ability to access real-time information on supply availability and prices supported by the demand offers unique opportunities to improve the overall efficiency of the grid in terms of both long-term supply-demand management as well as near-term dispatching of diverse generation facilities to meet current demand. The responsiveness and flexibility envisioned for the Smart Grid provides additional advantages in facing the significant new challenges of integrating distributed and intermittent generation capability such as small-scale generators and renewable energy sources (wind, solar, etc.) at a scale unmatched by current grid technology. This is becoming more critical as renewable energy technologies are playing an increasingly important role in the portfolio mix of electricity generation.

Develop leading-edge solutions using combinatorial optimization problems for steel and semiconductor manufacturers. Our solutions are based on advanced techniques from operations research, and artificial intelligence combined with industry experiences.
Production Design and Operations Scheduling (PDOS) is library of optimization based algorithms for scheduling the daily operations of a steel plant. It composed of six optimization modules: Inventory Application, Slab Design, Plate Design, Melting Shop Scheduling, Hot Mill Scheduling, and Finishing Line Scheduling. PDOS has been successfully deployed at several leading steel plants around the world.
