Using ChatGPT prompts to write your models makes it easier than ever for professionals to achieve accurate and efficient results, regardless of their expertise level.
AI tools, like ChatGPT, guide you through the process of developing optimization models in AMPL’s language. Whether you’re a seasoned expert or a newcomer, you’ll find the process intuitive and straightforward.
AI provides precise suggestions and automates complex tasks, ensuring that your models are robust and reliable.
Save valuable time and resources by leveraging AI to accelerate your model development process, allowing you to focus on strategic decision-making.
Developing optimization models has never been easier. With AI tools like ChatGPT, you can quickly generate and refine models in AMPL’s language, even if you’re not an expert in writing models. The AI provides step-by-step guidance, helping you create accurate and effective models effortlessly.
Example Use Case: Imagine you’re tasked with optimizing supply chain logistics. With ChatGPT’s assistance, you can develop a comprehensive model in AMPL’s language, addressing various constraints and objectives. The AI’s intuitive suggestions and corrections ensure your model is both accurate and efficient, ready to implement in real-world scenarios.
2. Provide Specific Constraints and Parameters
3. Define the Decision Variables
4. Specify the Objective Function
5. [Optional] Provide Data and Initial Values
6. Use Natural Language Descriptions
7. Ask for Specific Components
8. Request Example Models
9. Iterate and Refine
10. Highlight Common Pitfalls
Here’s how you can combine these tips into a comprehensive prompt for ChatGPT:
Prompt:
“I need to create an optimization model in AMPL for a supply chain logistics problem. The objective is to minimize the total cost, which includes production, transportation, and holding costs.
Decision Variables:
Constraints:
Parameters:
Please write the AMPL model for this problem, including the objective function, decision variables, and constraints.”
Based on the prompt above, ChatGPT should generate an AMPL model that includes all the specified elements. Here’s an example of what you might expect:
# Define sets
set FACTORIES;
set DISTRIBUTION_CENTERS;
# Parameters
param production_cost;
param transport_cost{FACTORIES, DISTRIBUTION_CENTERS};
param holding_cost;
param demand{DISTRIBUTION_CENTERS};
param max_production;
param max_inventory;
# Decision Variables
var x{FACTORIES, DISTRIBUTION_CENTERS} >= 0; # Units produced and shipped
var y{DISTRIBUTION_CENTERS} >= 0; # Inventory levels
# Objective Function
minimize Total_Cost:
sum{i in FACTORIES, j in DISTRIBUTION_CENTERS} (production_cost * x[i, j] + transport_cost[i, j] * x[i, j]) +
sum{j in DISTRIBUTION_CENTERS} (holding_cost * y[j]);
# Constraints
s.t. Production_Limit {i in FACTORIES}:
sum{j in DISTRIBUTION_CENTERS} x[i, j] <= max_production;
s.t. Demand_Met {j in DISTRIBUTION_CENTERS}:
sum{i in FACTORIES} x[i, j] + y[j] = demand[j];
s.t. Inventory_Limit {j in DISTRIBUTION_CENTERS}:
y[j] <= max_inventory;
s.t. Nonnegative_Inventory {j in DISTRIBUTION_CENTERS}:
y[j] >= 0;
