Summary:

The purpose of the land management is such investment decision
making, to gradually implement the principle of sustainable development.
Decisions concerning the locations of public investments have a major
impact on the economic development of the region. They should be taken
on the basis of previously developed and adopted strategy defined in a formalized
way. Decision-making problems can be solved with the use of the
optimization theory.
In the first part of the work the interpretation of the optimization
concept as an approach to solve the problem of location of objects of public
purpose investments was carried out. Every anticipated effect can be
expressed by a functional relationship. Finding the values of decision variables,
for which the function reaches a maximum or minimum in the set
of feasible solutions is the optimal variant of the investment project. So
raised problems also apply to the tasks performed in land management.
Proper location of the investments provides a sustainable management of
the environment resources giving benefits for the economy and society. To
actions in this area we are also obliged by the membership in the European
Union. Poland, as a full member of the EU, implements the rules which
are in force in the Member States. In the field of real estate management
among others land management guidelines are mentioned. From the EU
rules follows that the sustainable management of environmental resources
is reflected in the land management in three aspects: environment protection,
environment pollution and land reclamation. Development of the
methodology of the optimal site selection of public investments is one of
the activities leading to the implementation of EU rules in the sustainable
management of environmental resources.
In the second chapter the types of public investments in the real estate
management were indicated in relation to the provisions of the Law on
Real Estate Management. In terms of mentioned provisions the property
management was defined, as a set of legal, technical and economic actions
aiming to achieve an optimum condition of the property. This requires the
integration of property management with spatial planning, cadastral and
land register systems, and also the spatial data infrastructure.
The third chapter includes the interpretation and evaluation of the
multi-criteria decision making methods, used in the spatial decision analysis.
Performed review of the professional literature indicates yet slight use
of these methods in Poland. In the world multi-criteria methods are now
widely used in solving the engineering problems and increasingly in land
management when choosing the location of investments of public purposes
such as: airports, municipal wastes, industrial plants, etc. The assessment
of the methods used so far, showed their limiinvestment object specification, decision-making authority should be able
to optimize the location of the object in the given locality. The optimum
location is to provide the coordinates of the area characterized by the best
conditions in terms of the concerned criteria. For this reason, an attempt
was made to develop a methodology for the optimal choice of location of
public investments. Mathematical analysis and research carried out and
their results are presented in the following chapters of the work. The developed
model is based on the method of surface integration. The integrand
determines the surface formed by the criteria values in the nodes of
the squares grid. Data to achieve this objective came from available and
increasingly common spatial information systems. Model of the optimal
location of a public investment, includes in its algorithm the method of
analytical hierarchical process. Numerical visualization of areas optimal
to location of investment projects was developed in Delphi environment.
Methods of optimal location selection of public purpose investments
in land management together with the developed by the author LandRange
application overlay, has been tested on models and real objects.ted possibilities for combining
