Decision Support from the bottom up

PDC works with AI technologies

Artificial Intelligence

PDC develops Visual Prolog® which is a high level programming language with its roots in the logical programming language, Prolog. The Prolog language gives a strong advantage in implementing smart declarative models, doing rule based planning or using heuristics and constraints to solve problems.

Visual Prolog® is used for e.g. AI, mathematical optimization, expert systems and includes the best features of logical, functional, object-oriented and parallel programming paradigms.

PDC's Visual Prolog is the most widespread Prolog compiler

Our Most Valuable Tool

Visual Prolog® is focused at being the foundation for PDC’s applications. Firstly, it is a fast and safe programming platform, that fits into the various modern connected and layered IT architectures. Secondly, it is the ideal tool for solving problems needed in planning applications with optimisation, plan generation, problem solving and more.

Through time, Visual Prolog® has moved from being the 1st Prolog compiler in the world to be the most extensively used commercial Prolog compiler.

Many of PDC's solutions are based on AI and rule-based technologies

We Do Intelligent Planning

Since the foundation of PDC A/S almost 40 years ago, we strive to solve complex planning issues.

By combining the best features of logical and object oriented programming paradigms, we are able to solve specific tasks that benefit from rule based logical queries such as searching databases, automated planning and more. By using heuristic search and constraints, we can solve the most complex planning tasks, when no obvious solution is to be found.
