2. Such industries include:
o Construction
o Pharmaceutical
o Oil & Gas
o Military
o Supply Chain
o Logistics
Across many industries, optimizing resource management,
supply chain design and logistics is essential in minimizing
costs and keeping projects on time.
Project Management Optimization Needs
What is the Problem?
3. Cost over-runs are not uncommon because resources are not
optimally allocated to project tasks
Uncertainty in task duration caused by variations in crew productivity
Difficulty of scheduling payments to meet complex payment terms
Current tools designed to save time and money by optimizing project
management are lacking – they aren’t dynamic and very few provide
real-time feedback or other useful functionality.
What is the Problem?
Project Management Challenges
4. Optimizes the time-cost tradeoff (crashing) decisions with
complex payment structure and discounted cash flows
Sequential and adaptive solution approach to capture the
variation of project operations efficiency and productivity
A data-driven approach closing the gap between decision
support and the “big data” made available through IT
advancement

6. Optimization Model
OUTPUTS
• Option chosen (duration & cost) for
each task
• Start time of each task
• Maximum Return on Revenue
(ROR)
• Optimal project makespan
MIXED-INTEGER PROGRAMMING
(MIP) Model
Optimization Model for Maximum ROR
INPUTS
• Total project contract value
• Project makespan due date
• Duration of options for each task
• Cost of options for each activity
• Indirect cost rate
• Discount and interest rate
• Exogenous disturbances
7. Maximized return on revenue (ROR)
ROR Increased by 16% in a real-world construction
project case study involving only 8 tasks (details provided
in the handout)
Improved efficiency for project operations
Duration improved from 65 days to 59 days in the noted
case study
Improved quality of service delivery
Value Proposition
8. Optimizes the time-cost tradeoff (crashing) decisions
with complex payment structure and discounted
cash flows
Leverages the availability of data to provide data-
driven project scheduling and resource
distribution solutions
Market Use
9. Project Management for the U.S. construction
industry represents a significant, growing market
Estimated at $1.3 billion in 2018
Expected to reach between $1.62 billion and $2.71 billion by
2024
Growing at a CAGR of between 7.9% and 8.8% (2019-24)
Of smaller construction firms:
1/3 currently use construction software
1/3 used generic tools such as email/spreadsheets
28% cite improved workflow efficiency as their top need/priority
Sample Target Industry: Construction

12. A prototype has been developed with:
web-based architecture using ASP technology (eliminates the
need for user to purchase optimization solver);
successful integration of GUI, database and optimization
models; and
controlled user portal and privilege
Testing with real-world construction company data
completed
Development Stage
13. Design and development of user interface for enhanced
user experience
Automation of workflow for users with different roles in a
project
Cloud-based architecture to support mobile access
Seamless access and data exchange with project
management applications (e.g., MS Project)
Additional testing and de-bugging of the tool
Further Development Needed
14. Complex Projects need tools to effectively and efficiently
allocate resources
Resource allocation decisions have a huge impact on finish
times and ROR
Our technology provides dynamic optimization decision
support functionalities not offered in currently available
tools
Summary
19. • Labor Hours = Total Mhrs / Daily Output
• Daily Output is assumed to be a non-linear function of crew size to
model the diminishing return of crew size
