Opis:: Ze względu na powszechność i wielorakość zastosowań wykorzystuje się wiele definicji ryzyka, przy czym problemy z definiowaniem ryzyka w zarządzaniu wynikają zarówno z uwarunkowań ogólnych, jak i specyficznych. Jednocześnie można zaobserwować, że traktowanie ryzyka jako „mierzalnej części niepewności” staje się nieadekwatne do wymagań współczesnej teorii i praktyki. W artykule przyjęto podstawowe założenie epistemologiczne i metodologiczne, że konstruktywizm obejmuje również modelowanie matematyczne jako element narracji. Celem pracy jest dokonanie wstępnej interpretacji ryzyka w zarządzaniu jako konstrukcji społecznej. Artykuł stanowi wprowadzenie do pogłębionych badań dotyczących zarządzania ryzykiem w poszczególnych obszarach działalności przedsiębiorstwa.
Due to the prevalence and diversity of applications, a broad variety of risk definition have been elaborated. Problems with defining risk in management result both from general and specific conditions. At the same time, it can be observed that treating risk as a measurable part of uncertainty is inadequate to the requirements of contemporary theory and practice. The main assumption of the paper is that constructivism, including mathematical modeling as an element of narrative, constitutes the basic foundation of epistemological and methodological research. The aim of the paper is to develop a preliminary interpretation of risk as a social construction in risk management. The article is designed as an introduction to the in-depth research on risk management in specific areas of activity of company.

Opis:: Scheduling projects of linear or repetitive character (roads, pipelines, high-rise buildings) involves harmonizing a number of continuous construction processes to be conducted by specialized crews or machine sets executed at the same time in a number of work sections. Such projects are often modeled by time-distance diagrams that are represented graphically as an X-Y plot where one axis represents location, and the other time. Project planning involves allowing for construction-specific risks and is aimed at providing reliable schedules. These are to help the manager to assure that the project is completed by the predefined due date and, at the same time, that interruptions in work flow are avoided. In the case of repetitive processes, schedule robustness can be improved by providing time buffers between consecutive activities. The paper proposes an analytic method of sizing these buffers that assumes (as in PERT) that activity durations are stochastic variables whose distribution parameters can be defined on the basis of optimistic, pessimistic and most likely estimates. The method was used to construct a casestudy schedule, and the schedule quality was tested by means of simulation.

The Construction of the Portfolio of Contracts for Differences with Respect to Market Risk

Opis:: In this paper is considered the issue of the portfolio of contracts for differences (CFD). As far as the standards of contracts traded on the stock exchanges are precisely defined and treated in such a manner that the investor in case of adverse developments for him on the market have the ability to complete the required margin, so transactions on the over the counter (OTC) market do not give an investor such the comfort and can result in an immediate closing open positions with significant losses for the investor. Open CFD positions offered in the OTC market are continuously monitored in terms of fulfilment of the required security deposit (margin) and the investor is responsible for maintaining the necessary assets to fully cover the market risk. Creating a CFD portfolio investor faces a dilemma, what proportion of the funds allocated to the opening position, and which of them leave as a hedge against market risks. The Problem is so complex that many of the CFD is exposed to currency risk. Appropriate funds intended to cover unrealised losses has to secure against a ineffective margin call to supplement the security deposit and unfavourable for the investor closing his position. The work discusses the various measures of market risk exposure used by reputable financial institutions offering contracts on exchange differences on the over the counter market. In addition, proposed several measures to support the portfolio structure of the CFD, taking into account market risk.

Opis:: The goal of the paper was to present a case study of the preparations for the 2012 UEFA European Football Championship in Poland, and especially in Wrocław, in order to help the managers of similar multiproject undertakings in the future to manage more effectively the risk and to reduce to uncertainty linked to such projects. In the moment the paper is written, the preparations are on their way, and we already have had some difficult, but valuable experience. Several problems occurred which were threatening the success of the projects conducted in the framework of the preparations, several problems can still be expected in the basis of the experience. The problems from the past had to be solved somehow, the problems to be expected have to be managed also - all this may constitute valuable advice for similar projects in the future. To sum up the main problems that have been identified so far in the projects conducted in the framework of the preparations for the 2012 UEFA European Football Championship, we have to emphasize the legal problems. The law as it was formulated in the legal acts before the beginning of the preparations would have made them nearly impossible to be accomplished. Thus, several modifications had to be introduced. Also later the human nature which makes some people use the "holes" in legal acts for their personal advantage blocked the projects realization for a considerable period of time, which in case of projects which simply have to be finished in time, because otherwise we face a real disaster, is a very serious problem. The disputes concerned above all the land ownership and the bidding results. The long legal procedures of considering the appeals, the expropriation etc. were a real nuisance. Also it happened that a construction company which won the bidding did not accomplish what it was supposed to, thus we faced the necessity of changing a company, which made it necessary to deal with a an "empty" period where a new company had to be selected and the construction site had to be handed over. We hope that the present paper will allow other project managers to learn from the lesson our country and city has been going through at the moment and that the painful learning process we have been experiencing will be of use to someone else.

Tytuł:: Badanie wpływu zastosowania wymiaru fraktalnego na konstrukcję portfela optymalnego

Opis:: W pracy zbadano wpływ zastosowania nieklasycznej miary ryzyka inwestycyjnego, tj. wymiaru fraktalnego, na budowę portfela optymalnego. Miara ta określa zmienność stopy zwrotu i im większa jej wartość, tym większe ryzyko związane z inwestowaniem w dany instrument finansowy. Szacowanie tego wymiaru oparto na metodzie segmentowo-wariacyjnej. W badaniach pod uwagę wzięto finansowe szeregi czasowe złożone z cen zamknięcia akcji spółek notowanych na GPW w Warszawie.
In the paper studied the effect of application of non-classical measure of investment risk, i.e. fractal dimension, for building an optimal portfolio. This measure determines the variability of rates of returns and the greater value of this measure, the greater the risk associated with investing in the financial instrument. This dimension was estimated based on segment-variation method. The test will be conducted based on the financial time series which consist of closing prices of stock market indices and companies listed on the Warsaw Stock Exchange.
