Investment management in manufacture processesThe problem of this research is very urgent in present economical conditions. Frequent studies of this question confirm this opinion. A great number of papers devote to this item but substantially information set forth in the science literature is generalized; in numerous numbers of monographs considered to this question the particular items of Investment management problem are examined. It is necessary to take into account contemporary conditions during the study of this problem. High significance and scanty practical elaboration of Investment management in manufacture processes problem determine indubitable novelty of this research.

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.

The use of computer systems simulation of transport services in the field of steel trading
The article considers the task associated with the analysis and evaluation of business processes steel
trading company the company’s implementation of shipments from the supplier’s warehouse and optimization
of the transport customer service in the most efficient way as the related services are the
main activities of the company with a software environment that allows you to create and explore a
simulation model of logistics processes. It is expected the implementation of enterprise services for the
provision of transport services and increasing their share in the total volume of shipments of finished
products to customers. In the suggested model of estimation of efficiency of organization of transport
service of the steel trading company subject to the restrictions on the existing capacity, traffic and intensity
of service with the use of computer systems. The model takes into account the dynamics of the
flow of finished product from production to the warehouse of the trader inside the considered transportation
network to further its implementation, shipment and export. The problem posed in the article
is solved by means of economic-mathematical modeling.

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.
