The Concept of a Knowledge Base to Aid in Cost Estimating of Sports Facilities

Background. Reasoning based on cases is one of the heuristic techniques which is used in making right decisions in complex situations. Inference systems typically use previously acquired knowledge which is the basis for creating tools to represent and process information. So far, there has been a wide variety of solutions developed to make inference in conditions of incomplete knowledge, but this process appears in very few studies related to civil engineering.Research aims. This article will provide a concept of the model of knowledge base and a method of describing sports facilities. The cost estimation model will be based on the prices of the integrated works which, being based on the indicated system, will allow to create the module supporting cost and tender calculations. Methodology. The authors present the main assumptions of the concept of estimating the costs of sports facilities with the use of the system of inference on the basis of cases (CBR – Case-Based Reasoning).Key findings. The indicated method is designed to improve the accuracy of estimating the costs of planned sports investments and improve the decision-making process at the planning stage.
