Improvement of organizational and technological design of linear transport objects by modeling their spatial decomposition
One of the intractable problems of automation of organizational and technological design of transport facilities is the complexity of the formalized description of processes of interaction between elements of traffic system and ever-changing environmental factors. Changing environmental conditions over the linear object entails new constructive solutions on particular elements and corresponding amounts of work and technology. The article presents the approaches to sequential decomposition of a complex system of transport object first structural modules, and then - decomposition of structural modules into project and process modules. Discussed are options of design-technological module (DTM) for spatial road elements (permanent structure, construction) and linear structural modules of the object (roadbed, road pavement). The basis for DTM is the estimation of proximity of the constructive and technological solutions of particular elements. Special attention is paid to multilevel decomposition of the road and railway subgrade which is based on zoning road routes in terms of the homogeneity of the natural environment. The degree of homogeneity of natural conditions is estimated by variation coefficient using indicators of zonal, intrazonal and regional factors affecting constructive design of DTM subgrade. To solve this problem the algorithm and program using methods of geoinformatics and taxonomic analysis are developed. Spatial decomposition of linear object is the basis for making technological and organizational solutions on a DTM. For the design of the master schedule of construction organization previously developed with the participation of the authors of organizational-technological model and a program of integrated traffic are developed. The reference to calendar is made with MS Project Professional. The data on the use of the proposed method in practice of designing roads with the assessment of the efficiency of decisions are given.
