Nodal Economic Space Commerce (NESC) Model
The Nodal Economic Space Commerce (NESC) model is a dynamic, agent-based space market simulation and financial engineering tool
Agent-Based Modeling (ABM): allows heterogeneous agents with varied and dynamic behavior
- Simulation can represent plants and animals in ecosystems, vehicles in traffic, people in crowds, or autonomous characters in animation and games
- Qualities: emergent phenomena, natural description of system, flexible
Modeling space capitalism in NESC- Competition between firms, includes current and future competitors- Entrance of new competitors within existing and new markets - Explore variations in customer preferences- Current markets: sub-orbital space tourism and ISS support- Use available data for demand and to estimate supply
Companies compete for customers with the goal of maximizing revenues
- Each company autonomously decides its pricing strategy given its unique capacity, costs, and vehicle characteristics
- Model outputs financial health of each company- Capable of capturing differences in products/services

Modeling Assumptions for Vehicle Cost and Capability Inputs
Vehicles are available for purchase by the government agent in the year of their Initial Operating Capability (IOC)The government agent within NESC schedules all flights and ensures that the time between flights for each vehicle is not violatedCargo capacities shown represent the mass of cargo that each vehicle can deliver to ISS orbit (400 km altitude, 51.6 degree inclination) after taking into account structure of the vehicle, but not including any necessary tare (packaging) mass
- Average tare mass factors per cargo category are applied within the NESC model
Development costs are incurred for all vehicles, regardless of whether they are subsequently selected by the government agent or notThe production cost of each vehicle is incurred when selected and awarded a contract by the government agent
- Expendable vehicles are produced each time they are flown- Reusable vehicles are produced and can be flown until a failure occurs or they
have flown the input maximum number of flightsLaunch vehicle costs are independent of the crew and cargo vehicle costs and are incurred at every flightFailure cost is incurred by the company agent when a vehicle failure occurs and represents all costs to investigate the failure and make engineering changes

Use of COTS providers can potentially save the Government more than $4.5 Billion

ISS Commercial Transportation Services Market Conclusions
Agent-based modeling using NESC allows for a more realistic and dynamic simulation of traditional and emerging space markets
The two firms modeled in this effort can both be financially successful in the ISS crew and cargo services when vehicle failures do not occur
When vehicle failures are considered probabilistically, only a single firm of the two considered is financially successful in terms of mean NPV
- There is still some probability that the second company achieves a positive NPV- COTS companies should anticipate failure over the life of the program given the new products being
offered and flight rates required
The occurrence of failures increases the price charged to the Government and results in higher revenues for the participating companies
Use of commercial providers for resupply is potential win-win scenario for US Govt. and emerging commercial companies
- NASA savings might approach several billion dollars over seven year period (compared to using government CEV), commercial providers gain an entry market at an attractive price (possibly multi-billion dollar market is enabled)
- There is high reliance on ATV and Russian support for propellant re-supply, current study did not include any commercial company capable of providing such a service (could be a needed capability not addressed in the specific market segments requested by the COTS solicitation)
