A Knowledge Engineer (KE) can store computational model fragments in a Knowledge base. These fragments consist of relationships, formulas or tools with their validity, static data, descriptions, optional illustrations, properties and parameters. Since the output of one model fragment can be input for another, all components together form an undirected network of 'rules'. This network controls the data and calculation management capabilities of the system.

Quaestor applies a unique and advanced bi-directional chaining strategy of reasoning, computer algebra as well as network and relational database concepts. It offers a knowledge management environment and is able to invoke external executable programs, spreadsheets and databases.
A Domain Expert (DE) and Knowledge Engineer can use a knowledge base (network of model fragments) to determine or optimise any parameter used in any of the available formulas or model components (knowledge). This process is called Model Assembling and its result is a Solution.

Powerful document generation and browser facilities are available to present results, get information on intermediate calculations, the reasoning process and knowledge used in the solution.
Any modeling process results in a Solution. This Solution can be viewed in every detail defined by the Knowledge Engineer and can also be restarted using your new input.
