Making concerted investment decisions in cultural heritage management: algorithms of intellectual support

Cultural heritage (CH) is of great socio-economic importance. The problem of preservation and development of CH is vital for the cities of Russia. Due to the multidimensional nature of such problems, experts from different fields are involved to their solution, those often having not concurring interests. Thus, it is essential to improve the efficiency of the known mechanisms for making concerted investment decisions in the context of CH management problems. The main idea of the research is to improve the procedure for making innovative decisions agreed on the basis of generalized median schemes and to bring them to the level of tools. In the paper a substantial modification to the procedure for making such decisions is proposed, allowing for working out design decisions based on a set of matrix models showing preferences of different groups of experts in managing CH. The authors have elaborated procedures to harmonize functions of bringing CH phase characteristics and investment projects, to find concerted solutions when conducting a comprehensive assessment of investment projects and also a consistent model of preferences in the group of models of expert preferences, to harmonize matrix models of preferences based on generalized median schemes. The article also presents data of computing experiments confirming that the mechanisms proposed are effective, in particular in CH management tasks. The algorithms developed apply consistent models, which extend functional capacities of experts in handling problems of managing complex objects, including CH. These algorithms possess scientific novelty and the property of non-manipulability, they are brought up to the level of visual procedures and tools, which simplifies their use in economic research. This is especially essential in cases when persons involved in management have not quite matching interests. Selection of the most preferable investment projects results in increasing efficiency of control over economic processes.
