RESEARCH OF OPTIMAL TECHNOLOGICAL SEQUENCES IN THE ORGANIZATION OF CONSTRUCTION PRODUCTION

Abstract

The article discusses some problems of economics and organization of construction, which can be solved by linear programming using PTC Mathcad Prime, Excel Microsoft365 and data ranking. The authors analyzed the literature, which presents the existing optimization methods in various industries and the field of construction production. Shows the basic principles of using linear programming in various software tools. The authors analyzed in detail the comparison of different methods for the selection of optimal technological sequences. Examples of solving optimization problems in construction production by means of linear programming and data ranking method are presented. To solve the problem, the technology of applying the mixture to a vertical surface was used. Namely: cleaning the facade, plastering the surface, painting the surface. Three technologies were considered. For applying to a vertical surface using standard equipment are scaffolding, ladders and cradles. The process flow consists of the following processes: This is surface preparation. It can be performed in three ways: manual cleaning, sandblasting apparatus, hydrojetting. The next process is the technology of plastering the surface. At this stage, two options are considered: manual plastering and mechanized plaster application. Next, you perform a surface grouping process. This process can be performed either manually or using a pulvelizer. And the last process is painting the surface. Considered manual painting or mechanized device. The next step was to analyze the possibilities of each of the optimization search methods and provide recommendations for their possible application in solving similar problems. Created a mathematical model that can be scaled to implement optimization search in groups of technological sequences with different methods of work. Conclusions were also made regarding the use of the presented methods in solving similar problems of construction production.
This article may be an analog for calculating not only the mechanization processes, but it may become a meeting for automating the construction processes.
