Optimization models of the project to expand production in the decision support systemsThe purpose of writing of this article is development of optimizing models of the project of expansion
of production. Also, the aim of this work is to study the possible ways to integrate the developed
models in decision support systems. In models are considered including such factors as probable demand,
size of the order, restriction on material resources and capacities. The question of prospects of
attraction of the credit at implementation of the project of expansion of production is investigated.
These problems are solved about application of methods of research of operations. Also some practical
examples of use of the developed models at implementation of the project of expansion of production
for the enterprise making the innovative heating equipment are given. Thus the MS Excel program is
used. The developed models can be integrated into information systems of support of decision-making
that will allow to increase validity of the made administrative decisions. These models while integrating
them into the decision support system may be stored in the form of special programs, batch
files, modules, and spreadsheets.

Development of a software tool for finding the optimal portfolio of wholesale purchases of a trading enterpriseThe purpose of writing this work is to develop a software tool for finding the optimal portfolio
of wholesale purchases of a trading enterprise. The software is developed on the basis of the created
mathematical models and functional model. The mathematical models takes into account the restrictions
on the volume of working capital spent on wholesale purchases of goods, restrictions on the volume
of goods in the warehouse of wholesale purchases, demand constraints and some others. The functional
model describes the structure of the system for determining the optimal portfolio of wholesale
purchases of a trading company and created on the basis of graphical notation IDEF0. The operation
principle of the algorithm is illustrated by a block diagram. The algorithm of the software is based on
the branch and bound method. The work of the software is demonstrated on a practical example of
searching for the optimal portfolio of wholesale purchases of ventilation equipment. A software tool
can be of interest to managers who are developing a wholesale purchase plan.
