Development of a web-based platform to support business logic in computer-aided design systems for construction facilities based on graph-oriented modeling

Abstract

The article presents a universal web platform designed for the formalization and execution of business logic in computer‑aided design (CAD) systems of construction facilities. The methodological basis is a graph-oriented approach: the technological cycle is described in JSON format as an oriented graph, where the vertices correspond to the design stages, and the edges correspond to acceptable transitions with a set of predicates. When loaded, the graph is transformed into an internal model, stored in a relational database, and validated based on topological sorting and breadth-first traversal, which allows you to identify cycles and logical contradictions. The server part is implemented in Python (Django), which forms REST endpoints; the Jinja template engine dynamically generates editable HTML interfaces. The process of static calculation of a reinforced concrete beam in SolidWorks Simulation was considered as an experimental case: the prototype reduced the calculation preparation time by 35% and reduced the number of critical errors among novice users. The scalability of the solution is shown — support for various types of calculations (thermal engineering, wind), as well as the possibility of integration into BIM environments. The proposed platform forms the basis for building adaptive, multi‑user web-based support systems for the life cycle of a construction facility.
