ALGORITHM FOR THE MULTI-CRITERIA DESIGN OF THE STRUCTURE OF ROOF AND FLOORS BASED ON USER PRIORITY
Abstract
This paper describes an algorithm that proposes compositions of structures that are in contact with the cooled environment based on the user's priorities. Specifically, the algorithm evaluates the construction of floors, flat, and pitched roofs. The algorithm compiles these structures based on individual technical criteria and their set priorities in combination with the price of materials. Multi-criteria methods such as the Saaty method and the weighted sum method are using to determine the importance of individual criteria. The user selects some criteria that are essential to him and must score them with each other on a scale of 1 to 9. Using this Saaty method, we gain the importance of each criterion. Using this Saaty method, we obtain the importance of individual criteria. The Analytic Hierarchy Process method (AHP), namely the weighted sum method, is used for the conversion of technical measures to the interval between 0 - 1. The main purpose of the algorithm is to find the best structure with the required technical criteria at the lowest possible price. Of course, the user can specify the main criterion other than price. The algorithm can work with up to 7 criteria. The criteria will be price [CZK/m2], heat transfer coefficient [W/(m2.K)], maximum area load [kN/m2], specific heat capacity [J/(kg.K)], acoustic attenuation [dB] and the last will be an environmental criterion or Life cycle assessment. There are two sub-criteria, namely the amount of waste in production [kg/FU] and the global warming potential [kg CO2/FU]. The algorithm should use the material data analysis and multi-criteria analysis theories to find the structures with the highest benefit value for the user. If the price is the main priority, then the composition of the structure is designed in the ideal ratio of technical performance versus price. At present, there is no software on the Czech market, analyzing compositions from a financial perspective. The proposed algorithm helps with sustainable construction.
