COMPUTER SUPPORT
MANAGEMENT WITH MANUFACTURING PROCESS OF PREFABRICATED CONCRETE ELEMENTS
In the paper on the base of case
study of manufacturing process in civil engineering firm and available domain
literature one can proof that applied computing solutions for manufacturing
production support are not fully used in practice of enterprise management.
There were describe some aspects of unusual usage of computer methods to suport
block machines and manufacturing moulds management by creation a number of
appropriate measures and indexes.
In the paper one can presented
potential possibilities of the computing system. Namely, in the frame of
introduced computing system statistical data concerning single Shift of a given
product can be groupped and on this base one can conclude about productivity
and manufacture quality.
However currently, elements
concerning recording a number of empty tops or tops including products not
satisfying norms are omitted. Taking attention that shift report is closed
before final evaluation of product quality there is no possibilites to complete
mentioned above analysed data. Hence, information on a level of products
quality, productivity and efficiency is not enough.
So, computer programme will be not
fully used and its simple modification in this scope is hardly possible.
Positive example for usage of IT for
CEGTOR managementis supporting management with block machines begin crucial
technological elements. It is made through especially dedicated software
application. Introduced system enables acomparison of life time of block
machines and evaluation of quality of their performance by manufacturers.
Received information is used during negotiations with suppliers concerning
succesive purchases of block machines.
So, the findings let conclude that
it could be justified to develop some of introduced in CEGTOR firm tools
towards their better adjustment for decision making needs under its specific
organizing and technical circumstances what let use more effectively generated
reports through the management staff.

APPLICATION OF
DE BONO’S CREATIVE THINKING IN THE IMPLEMENTATION OF SMED ON THE EXAMPLE OF THE
PRACTICAL
TPM is a very powerful tool used to
improve the organization. It is also difficult to implement. To assist in the
introduction of TPM method Edward de Bono Has been used. Method six ways of
thinking can by use to organize any work on each issue. The method is neutral
and can be used as a game or ritual that helps people to follow certain rules. Using
de Bono methods in the company management helping to consistently and correctly
apply the techniques of TPM and allows us to obtain:
- SMED
allowed the efficient carrying out refitting of individual machines,
- reduction
in the time machine refitting from 25 to 10 minutes,
- reliability
of machines up to 100%.
Still current problem of Polish
economy is insufficient growth and development. The main reason of this is the lack
of innovative solutions in the sphere of production and service. Innovation
should be present in all phases of business. Starting from design, through
product, marketing, customer service, management, set a price for ending
controls. Innovations emerging in the enterprise are closely linked to the
emergence of new knowledge about the market, competitors, customers, the
achievements of science and technology, and financial and legal arrangements.
Implementation of a new product, or technical organizational solutions, can
provide tangible economic and social benefits. They can relate better use of
time, manpower, means of production, saving materials and many other fields.
The mainfactor influencing to the effectiveness of these changes is the
efficient management of innovation activities that can be supported by the
psychology of creativity. Creative thinking brings many benefits. It is
necessary to invent more and better ways to design innovative technology,
marketing or search for new ways to motivate employees. This difficult
requirements can meet only organization that is so creative, that depends on
continuous development and improvement. Determination of conditions for the
transfer process of individual creativity on the level of teams and the organization
seems to be a major problem in practical use of creativity in organization and
management. Creativity and innovation are overlapping structure between the two
stages of the creative process: idea generation phase and the phase of
implementation. Creativity combines these two processes: the formation of ideas
and giving them concretesolutions.

THE IMPACT OF
AUTOMATIZATION AND ROBOTIZATION FOR THE ORGANIZATION OF PRODUCTION ON THE
EXAMPLE OF PREFABRICATED CONCRETE
The article discusses problems related
to automatization and robotization in industrial production. The increasing use
of automatization and robotization in the industry encounter problems related
to the proper organization of production. Characteristics of simple automatization
and flexible automatization and its influence on production organization were
presented. Also the factors influencing the increasing use of robots in
industry are discussed. Thanks to their large capacities robots are
increasingly replacing human labor and for example are used for carrying heavy
loads. Examples of the use of automatization in the production of prefabricated
concrete blocks are presented. The effects of automatization for the
organization of production process were showed on the example of nonautomatized
production, half automatized mobile block making machine and fully automated
line for prefabricated concrete blocks. Computer models of those three variants
of the production are described and the results of the simulation experiment
were presented. Simulation results clearly show the great impact of automation
on productivity, which is much higher than in nonautomatized production.
Computer simulation combined with visualization of the production process
allows analyzing different organizational solutions. The computer model of
production system can be the relatively simple modified and the impact of
changes on the process of production can be analyzed. This allows to predict
the behavior of the real production system and choose the best in the given
situation organizational solution.
Remains to consider the economic
aspects of the implementation of automation, which were not taken into account.

USE SIMULATION
TO IMPROVE FLOW CONTROL IN FURNITURE MANUFACTURING COMPANY
Computer simulation techniques have
been used in the issues of production for about 30 years. Due to the rapid
technological progress in the field of IT and growing computing power of
personal computers attractiveness of simulation still increases. The advantage
of computer simulation is its repeatability. By setting a number of the model
parameters and by assigning numerical settings we can repeat the same process
many times which is impossible to achieve in the real world.
All the manufacturing systems can be
divided into two parts: process and discrete systems. The products of the process
manufacturing once put together cannot be taken apart. Discrete manufacturing
can be characterized by individual or separate unit production. The sensible
use of simulation usually requires the knowledge of the theoretical background
to discrete simulation such as probability distributions, the model building
process including validation techniques and the design of experiments.
This study aims to present method
for improving the flowin discrete manufacturing in exemplary company of
joinery. The main goal of the research was to identify the actual and potential
problems inside of the manufacturing system. Large intermediate stocks, long
through put times, and variable bottlenecks are the most common kinds of
problems that usually characterize such an environment. Furniture manufacturing
is the complex process that consists of a few steps. The characteristics of the
current manufacturing system in descriptive and schematic forms were presented.
In the next stage the model of existing manufacturing system using the selected
simulation software was developed. The model included such elements as:
storages, works transportmean, assemblers, workstations, etc. The final step
was to conduct a simulation experiment and draw conclusions. In this case, the
method allowed to develop a computer simulation model that reflected the actual
functioning of joinery company. The experiment conducted in conjunction with
the simulation model provided detailed data for a thorough analysis of the flow
in manufacturing. Some results of the simulation experiment were compared to
the historic real company data and in this way the high quality of the simulation
model was proven. This way the main barrier in obtaining the higher
productivity level and the cause of excessive intermediate stocks were
identified. Appropriateremedial steps leading to improve the flow in
manufacturing, release of capacity reserve and reduce of stocks levels were
proposed.

MANAGER’S ROLE
IN CONTEMPORARY MANAGEMENT ORGANIZATION
Challenges of the XXI century affect
the process of development and the pursuit of business excellence. This is
evident in several areas, notably globalization and internationalization of the
world economy. Multinational companies increasingly seek newer markets and
cheap labor. This affects the development of investment in less developed
countries. Analyzing the failure of the pioneers of the company or its
competitors in the industry, they implement the latest technologies by
eliminating the twenty first century in effective. The dynamism of the global
economy causes acontinuous process of improving the operation and management of
many companies. Entrepreneurs do not keep up with the productive and very fast
in practice use of knowledge and information. The phenomenon of
entrepreneurship is an essential element of economic competitiveness in world
markets and many large and small businesses. What actually is meant by saying
to be enterprising. Assumed that to be entrepreneurial, it means to be
creative, innovative, flexible. Every manager, regardless of specialty, and
level of function in addition to act as one plays in the organization the
social roles expected by other members. The article presents the nature of the
manager’s work, types of managers, managerial job requirements and principles
of work organization, as well as key roles and skills, in terms of modern
management.

SIMULATION OF
THE PRODUCTION LINE WORKING ON THE BASE OF A PRACTICAL EXAMPLE
After gathering information about
production line and processes realizing on the line, the current state of the
value stream map was drawn. On the base of the map analysis and talks with
employees and management the improvements, which could improve production line
working and its capacity, were proposed.
Improvements were discussed and chosen of them were indicated to check in
simulations.
Then a first version of future state
of value stream map with the indicated improvements was prepared.
To do simulations a plan was
developed. As variables are taken: frequency of delivery, effective working
time, number of simultaneously assembled products, number of lathes in the line
and number of products in batch.
Next a model of the production line
in ProModel program was build. With the use of the model, in the range of the analysis,
144 simulations were done. Obtained data are analyzed and proposals for line
developing are presented.
To increase production line capacity
an additional lathe has to be introduced into the line. Authors also indicate
that morning break should be cut down to 5 min. Another solution, which has to
be introduced, is changing a frequency of delivery. The frequency should equal
8 hours and it is enough. More often deliveries are not cost effective,
although they could give even beter capacity.
It was impossible to double capacity
by introducing only other improvements avoiding costs concerning with necessity
of buying a new lathe.
The proposals are shown in the
second version of future state of value stream map. Authors also indicate the
further possible development and analysis.
