Types of Planning in Artificial Intelligence: Tools and Applications

Every day, AI systems are taking on increasingly complex tasks, whether it's navigating traffic, diagnosing diseases, or managing supply chains. But behind these advancements lies a crucial capability, “Planning in AI”. 

With AI set to contribute $15.7 trillion to the global economy by 2030, types of planning in artificial intelligence are key to enabling machines to make decisions that drive innovation across industries.

In this blog, we'll break down the different types of planning in artificial intelligence, explore why they're essential, and how they're shaping the future of automation.

What is Planning in Artificial Intelligence?

Planning in AI refers to generating a series of actions to achieve a goal, similar to human problem-solving. This means the AI looks at where it is starting from (the current situation), decides what it wants to achieve (the goal), and then works out the best sequence of actions to get there. 

According to a 2023 Gartner report, 58% of enterprises have already implemented AI-driven planning systems to improve operational efficiency and decision-making.

The AI planning works in 3 basic steps: 

• It breaks tasks into steps
• Picks the best routes using algorithms.
• Adjusts plans if conditions change. 

For example, if a robot needs to deliver a package, it plans each move to drop off a package, and if it finds a hallway blocked, it quickly reroutes to reach the destination. 

Let's now explore the importance of planning in AI systems and how it drives AI's effectiveness.

Importance of Planning in AI Systems

• Goal-Oriented Action: Planning enables AI to determine the correct sequence of actions to meet specific goals, closely mimicking human decision-making for optimal results.
• Systematic Approach: AI systems map out tasks, select suitable algorithms, and apply performance metrics, enhancing efficiency across complex projects.
• Resource Optimization: Effective planning ensures efficient resource use in complex AI tasks, especially when resources are limited.
• Improved Decision-Making: AI planning evaluates multiple factors to help systems choose the best course of action, resulting in better decisions.
• Automation of Complex Processes: AI planning automates intricate tasks, reducing human input and boosting accuracy.
• Adaptability and Monitoring: AI systems continuously adjust plans as conditions change, ensuring ongoing effectiveness and adaptability through real-time responsiveness.

Now that we've seen how planning shapes AI decision-making, let's dive into the different types of planning in artificial intelligence that make this possible.

Types of Planning in Artificial Intelligence

Planning in AI isn't one-size-fits-all. Depending on the task, AI uses different types of planning to solve problems more effectively. So, what are the different types of planning in artificial intelligence, and how do they work? Let's break them down.

1 Classical Planning

Classical planning assumes a fixed, predictable world where the AI follows a set sequence of actions to reach its goal. The world is described using logical facts in languages like STRIPS or PDDL, making it easy for the AI to "see" all aspects of the problem at once.

Each action has a well-defined, predictable outcome. There's no uncertainty, if you perform action A in state X, you always get state Y.

Example: A chess engine planning its next move in a game where all pieces and rules are known and unchanging.

Because everything is known and fixed, classical planning can quickly find optimal solutions in domains like puzzles, board games, or basic automation.

2 Hierarchical Planning

Breaks complex problems into smaller sub-problems, creating a hierarchy of plans. This structure enhances efficiency, a key aspect of types of planning in artificial intelligence.

Subplans can be reused in different parts of the plan or future planning problems, saving time and effort.

Example: An industrial robot assembling a car: the top-level plan is "build car," with sub-plans for "install engine," "attach doors," and so on.

Here, by tackling one layer at a time, the AI can efficiently handle large, complicated tasks that would be overwhelming if approached all at once.

3 Temporal Planning

It focuses on managing tasks with specific time constraints and dependencies, ensuring actions are sequenced within specific time limits. This is crucial in types of planning in artificial intelligence where timing matters.

Example: A hospital scheduling system plans surgeries so that operating rooms and staff are available at the right times.

It is ideal for environments where timing is crucial, like scheduling, logistics, and real-time systems.

4 Forward State Space Planning (FSSP)

It starts from an initial state and applies actions sequentially to reach the goal state, exploring possible future states along the way, with types of planning in artificial intelligence.

Example: A delivery drone planning its route from the warehouse to a customer’s address. Starting at the warehouse, it considers each possible move (such as fly north, east, or avoiding obstacles), step by step, until it finds the quickest path to the destination.

Especially useful when the initial state is clear, but there may be multiple possible goal states.

5 Backward State Space Planning (BSSP)

Works backward from the goal state, identifying actions to reach the target. This reduces search space complexity in types of planning in artificial intelligence.

Example: A chess program wants to achieve checkmate. It starts from the checkmate position and works backward, identifying which moves could have led to that state, eventually mapping out the sequence of moves needed from the current game position to win.

It is also known as regression planning, as it regresses from the goal to the start.

6 Goal Stack Planning

It combines FSSP and BSSP using a stack structure to manage goals and actions, ensuring systematic achievement of objectives in different types of planning in artificial intelligence.

Example: A cooking assistant robot stacks up tasks like "boil water,” "chop vegetables," and "serve a meal," working through each step in order.

Works best in environments where tasks and dependencies are well-defined and predictable.

7 Non-linear Planning

It is also called partial-order planning and allows multiple goals to be pursued simultaneously, optimizing solutions based on various interactions. Although it comes with a more complex search space compared to other types of planning in artificial intelligence.

Example: A project management AI coordinates multiple teams working on different parts of a software product at the same time.

It effectively manages tasks that depend on the completion of other tasks, making it suitable for dynamic and interconnected projects.

Here’s a quick comparison of the types of planning in AI:

Since we’ve outlined the types of planning in artificial intelligence, let’s look into the tools and techniques that make these planning methods work efficiently.

Tools and Techniques for AI Planning

AI planning relies on a range of specialized tools and techniques to model, solve, and optimize complex decision-making tasks. These methods enable AI systems to generate effective plans, handle constraints, and learn from experience to improve future outcomes.

Here are some go-to tools to build AI planners: 

• Automated Planners: They are programs that autonomously generate plans, with frameworks like STRIPS (Stanford Research Institute Problem Solver) and PDDL (Planning Domain Definition Language) used for defining planning problems.
• Constraint Programming: This powerful technique allows for modeling and solving complex planning issues that involve multiple constraints. CP is frequently integrated with AI planning systems to handle resource allocation, scheduling, and optimization.
• Machine Learning: Reinforcement learning, a subset of machine learning, enhances planning by learning from past experiences and refining strategies based on feedback. RL can be combined with constraint programming to automatically tune models, learn constraints, or optimize preferences.
