Study Notes
Integer Programming Overview
- Integer programming (IP) is a mathematical optimization method where some or all decision variables are restricted to integer values.
- Applications often involve yes-or-no decisions, making it suitable for problems with discrete choices.
Example: California Manufacturing Company
- The company is exploring expansion options by constructing a new factory in Los Angeles or San Francisco, with a possibility of building one warehouse at a factory site.
- The net present value (NPV), which considers profitability over time, is provided for each option.
- Total capital available for investment is set at $10 million.
Key Properties of the Problem
- Decisions involve mutually exclusive alternatives, meaning if one option is chosen, others cannot be.
- Constraints can require that the sum of binary variables (representing yes-or-no decisions) equals one (if exactly one decision must be selected) or is less than or equal to one (if at most one can be chosen).
- Contingent decisions may arise, where the choice is dependent on prior decisions.
Practical Applications
- Common scenarios in industries like manufacturing, logistics, and project management leverage integer programming for optimal resource allocation.
- IP can effectively handle complex decision-making processes with limited resources.
