Production systems are computer programmes that give AI. It consists of a set of rules about behaviour and includes the mechanism required to follow those rules as the system reacts to external conditions.
In AI, a production system consists of a global database, production rules, and a control system. These systems are monotonic, partially commutative, non-monotonic, and commutative.
Why is it important?
Production management enables the company to compete in the marketplace. Production management creates items with the proper amount, quality, pricing, and timing. These products are given to consumers according to their specifications.
Procedure
There are two parts to production: a sensory precondition (or "IF" statement) and an action (or "THEN"). When the prerequisite for a production matches the way the world is right now, the production is said to be triggered. When a production's action happens, this is called "firing." A production system also has a rule interpreter and a database, sometimes called "working memory", because it stores information about the current state or knowledge. When more than one product is triggered, the rule interpreter must have a way to decide which one comes first.
Basic Operation
Rule interpreters usually use a forward chaining algorithm to choose which productions to run to meet current goals. It can include updating the system's data or beliefs. The left-hand side, or LHS, of each rule, is compared to the current state of the working memory.
In idealised or data-driven production systems, it is assumed that any triggered conditions should be carried out: the actions that follow (the right-hand side, or RHS) will update the agent's knowledge by removing or adding data to the working memory. When the user stops the forward chaining loop, when a certain number of cycles have been done, when a "halt" RHS is executed, or when no rules have true LHSs, the system stops processing.
On the other hand, real-time and expert systems often have to choose between actions that can't be done together. For example, activities take time, so only one can be done or suggested in the case of an expert system. In these kinds of systems, the rule interpreter or inference engine cycles through two steps: matching production rules against the database, then choosing which of the matched rules to apply and carrying out the actions chosen.
Conclusion
Production system applications range from simple string rewriting rules to the modelling of human cognitive processes, term rewriting and reduction systems to expert systems.
Production systems are an outstanding tool for organising AI programmes. Each rule can be added, withdrawn, or modified independently, rendering Production Systems highly modular. The disadvantage is that there need to be more learning results from a rule-based production system that does not save the problem's solution for future use.
Furthermore, the production process is how the inputs of resources, called "factors of production," are turned into goods or services. Capital, labour, technology, land, and other things used to make goods and services are called "factors of production."
