Discussions and Results. Despite the changes in the main planning issues intended, it has remained almost the same for the last two decades. Later, the following began to appear as important factors in regional planning:
1. Fundamental uncertainties regarding economic development in the medium and long term have increased.
2. Economic integration has increased both domestically and internationally, which means that regions are increasingly exposed to external economic processes.
3. The shortage of fuel and other raw materials led to focus on the analysis of important economic processes to the problems of technological change.
The above-mentioned three points do not refer to regional processes, but represent examples of general economic phenomena that have regional impact and may have a significant impact on regional development in the future. Changes in economic development, ie economic stagnation or rapid structural changes in industries, even in highly industrialized countries, other features of this new order may imply new regional growth patterns at the national and local levels.
It should be noted that there is a significant difference in emphasis on regional modeling between market and planned economies. North American research focuses on urban modeling, whereas in the former union states, planning can be seen with a strong emphasis on multi-regional analysis or analysis of non-urbanized areas. This change at the regional level is reflected in the increased interest in econometric analysis and the widespread use of simulation models for urban modeling in North America.
There is a wealth of information on regional modeling from a Western European perspective. It is an example of another trend of modern regional economic modeling, the connection of real and financial economic models. This is the answer to the economic integration problem mentioned above. In the context of high inflation, it is very important to study the relationship between price systems and technology. Another feature of current multi-regional modeling presented in these reviews is the desire to link models of regional subsystems. The increased interest in large-scale models is reflected in the desire for an applicable multi-regional, multi-sectoral model with significant network and territorial differentiation.
Another example of interest in coupled model systems is the growing focus on the economic aspects of migration processes and the determinants of labor supply. It also shows a trend towards more accurate solutions to uncertainty and multi-objective problems, which is a very important topic in the field. As some important practical problems of transferability between theoretical models, practical models and the computer programs required for such models, practical regional modeling should focus on maintaining a balance between generality and specificity, not only theoretically, but also in computational practice. The compatibility of theoretical and practical versions of regional economic models is very important for the reliability of modeling processes, and therefore system analysts should take it more seriously. Although regional planning has long been recognized as a field characterized by multiple and conflicting objectives, the application of models using multi-objective techniques is rare.
Applied regional systems analysis cannot be used to generate simple quantitative results. The focus on long-term policy issues makes it impossible to derive any policy recommendations that are sufficiently specific for immediate action. A more realistic goal would be to use models to develop quality policy recommendations in the form of general guidelines. In some cases, even this goal is not achieved; however, regional system analysis applied in this context can always be used to gain a better understanding of long-term regional policy issues and their interactions.
In the analysis of regional systems, it is often necessary to create a large number of forecasts showing the consequences of different courses of action and different forms of development, and these forecasts can be very useful for regional planners. Creating these scenarios is an important part of the planning process. Planning scenarios can be developed through a purely verbal process, sometimes aided by road maps, as in physical planning. However, experience shows that this type of process is only viable if the number of planning variables is small.
Computer-aided planning processes become necessary as the size and level of resolution of the problem increases. The economic structure of the area can be seen as the first dimension of the planning process, the spatial structure as the second dimension, and the temporal sequence of activities as the third dimension. If it is assumed that the economic structure can be represented by 30 production sectors, the spatial structure by 10 subregions, and the temporal structure by 3 periods, a model that includes all interrelationships will need to account for 900 variables. It would be very difficult to design such a system without the help of a formal computer model.
Early planning theory often assumed that a large system of this type would necessarily have a single objective function that should be maximized given certain technological constraints. Adopting the same planning philosophy, a giant model structure for the whole system and maximization of the objective function depending on the allowed variation of variables and these variables can be considered as planning tools. As discussed in the review of current research on multi-objective decision analysis, a priori selection of a single objective function is a difficult and risky task. A more realistic approach would be to propose several possible objective functions and then explore the range of solutions obtained. In this way, the problems of combining conflicting objectives could be avoided, but the approach still suffers from the difficulties inherent in solving large-scale systems.
Unfortunately, the numerical capabilities of any optimization model including spatial, sectoral and temporal dimensions are still very limited. Another problem is the existence of clear and statistically reasonable technological restrictions on many planning models. In particular, many economic planning models include reasonably clear restrictions on the use of primary resources, labor and other factors affecting production.
Network correlations can also be defined with some degree of precision. However, it is much more difficult to identify the behavioral constraints governing the activities of households and other decision makers in an economic system. Thus, any optimization model used for economic planning does not include very accurate descriptions of human behavior. This means that the behavior of decision makers and planners and their interactions must be modeled more closely using optimization models for process control.

In the analysis of regional systems, it is often necessary to create a large number of projections showing the consequences of all courses of action and different forms of development, and these projections can be very useful for regional planners.

As discussed in the review of current research on multi-objective decision analysis, a priori selection of a single objective function is a difficult and risky task. A more realistic approach would be to propose several possible objective functions and then explore the range of solutions obtained. In this way, the problems of stacking conflicting objects could be avoided, but the approach still suffers from the difficulties inherent in solving large-scale systems. Unfortunately, although the numerical capabilities of any optimization model, including spatial, sectoral and temporal dimensions, are very broad, lack of data arises as a problem.
Many planning models can be given precise and statistically reasonable technological constraints: this is certainly true for resource use constraints. Many economic planning models include reasonably clear restrictions on the use of primary resources, labor and other factors affecting production. Network correlations can also be defined with some degree of precision. However, it is much more difficult to identify the behavioral constraints governing the activities of households and other decision makers in an economic system. Thus, any optimization model used for economic planning does not include very accurate descriptions of human behavior. This means that the behavior of decision makers and planners and their interactions must be modeled more closely using optimization models for process control.
A broad description of the evolution of regional development process modeling over the past twenty years is given, and the theoretical foundations of this type of analysis are reviewed. Based on the considered opinions, the development of modeling methods in the research work was summarized and some methods and practical use of models were discussed.
