PDC is a 100% Danish-owned, high-tech software house working within resource planning and scheduling. Our stated goals are:
- To lead internationally in the development of knowledge-based systems, expert systems, and logic programming.
- Additionally, we aim to apply this technology to practical applications with our customers, providing tangible benefits that often integrate closely with other computer technologies.
- Moreover, our clients operate in dynamic and time-constrained environments.
Today, we deliver business-critical solutions for resource planning and optimization in industries characterized by high dynamics, complex rules and constraints. For almost 40 years, companies in Denmark and around the world have used PDC’s unique knowledge-based technology to implement effective decision support in connection with various types of planning.
Typically, our customers typically work in time-constrained environments, and we provide them with automation and intelligent decision support that enables them to optimize their business processes.

Decision Support from the bottom up

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.

Our Most Valuable Tool
Visual Prolog® focuses on being the foundation for PDC’s applications. Firstly, it provides a fast and safe programming platform that fits into various modern connected and layered IT architectures. Secondly, it serves as the ideal tool for solving problems in planning applications, including optimization, plan generation, problem solving, and more.
Over time, Visual Prolog® has evolved from being the first Prolog compiler in the world to becoming the most extensively used commercial Prolog compiler.

We Do Intelligent Planning
Since PDC A/S was founded almost 40 years ago, we have strived to solve complex planning issues.
By combining the best features of logical and object-oriented programming paradigms, we 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 tackle the most complex planning tasks when no obvious solution is available.
