Opis:
Prospective financial analysis is a key decision tool in an enterprise. The traditional approach confronts the forecasted value of a financial category or a financial ratio with a requirement or a standard. Knowing that the particular category or the ratio meets the requirement or the standard is a kind of risk information, but realizing that the requirement or the standard is met with a particular probability level is a detailed image of risk. The aim of the paper is to indicate the possibility to increase the effectiveness of prospective financial analysis by using a Monte Carlo simulation. The biggest advantage of the presented approach (that is in fact the evolution of the traditional scenario approach to risk analysis) is that it delivers the detailed probability distributions of key financial categories and ratios. Shareholders accepting the results of prospective financial analysis with the Monte Carlo simulation should accept risk in a more conscious way than in the case of the traditional approach

Opis:
A non-financial enterprise with receivables or liabilities denominated in a foreign currency is exposed to currency risk. Wanting to calculate a financial reserve in order to secure its receivables or liabilities, an enterprise can introduce the concept of the value at risk. To determine value at risk, an enterprise has to know the probability distribution of the future value of the receivable or the liability for a specific moment in future. Using a geometric Brownian motion to reflect exchange rate changes is among the possible solutions. The aim of the paper is to indicate that using the Monte Carlo simulation for forecasting the currency risk of an enterprise is a clear, easy-to-implement and flexible in terms of the assumptions approach. The flexibility of the Monte Carlo approach relies on the possibility to take up the assumption that the currency position changes caused by currency fluctuations have an other than normal probability distribution.

Opis:
The Monte Carlo simulation is the ultimate solution for considering nearly all possible scenarios in presumably any discounted cash flow valuation. This paper argues that a discount rate expresses an investor's current requirement and should be respectively perceived as a parameter only. The consequences of qualifying a required rate of return (a discount rate) as a risk factor in a discounted cash flow valuation are described in the paper using a free cash flow financial model of an asset being a hypothetical publicly traded enterprise. The case study is a discounted cash flow valuation using the Monte Carlo simulation for risk analysis. The various sets of assumptions are considered to explain the consequences of qualifying a required rate of return in a discounted cash flow model as a risk factor. As indicated in the paper, the discount rate as an additional risk factor with an attributed probability distribution increases the volatility of a risk variable, then the distribution of a risk variable becomes more flattened. In previous studies, some authors indicated that a discount rate could be considered a risk factor in the Monte Carlo simulation (Krysiak 2000; Damodaran 2018).
Symulacja Monte Carlo jest narzędziem umożliwiającym rozważenie „prawie wszystkich” scenariuszy w dowolnej wycenie/ocenie wykorzystującej zdyskontowane przepływy pieniężne i uwzględniającej ryzyko. Zdaniem autora stopa dyskontowa jest wyrazem bieżących żądań w zakresie rentowności. Należy ją zatem postrzegać jako parametr. Konsekwencje kwalifikacji wymaganej stopy zwrotu (dyskontowej) jako czynnika ryzyka w wycenie zobrazowano w artykule z wykorzystaniem modelu finansowego aktywa stanowiącego hipotetyczne przedsiębiorstwo notowane, wykorzystującego wolne przepływy pieniężne. Studium przypadku stanowi wycenę aktywa z uwzględnieniem ryzyka poprzez implementację symulacji Monte Carlo. W celu zobrazowania kwalifikacji stopy dyskontowej jako czynnika ryzyka rozważono różne zestawy założeń dla symulacji. Należy stwierdzić, że stopa dyskontowa stanowiąca dodatkowy czynnik ryzyka z przypisanym rozkładem prawdopodobieństwa zwiększa zmienność zmiennej ryzyka. Rozkład zmiennej ryzyka ulega spłaszczeniu. W dotychczasowych badaniach wskazywano, że stopa dyskontowa może być traktowana jako czynik ryzyka w analizie ryzyka z wykorzystaniem symulacji Monte Carlo (Damodaran, 2018; Krysiak, 2000).

Opis:
An indication of correlation between dependent variable and predictors is a crucial point in building statistical regression model. The test of Pearson correlation coefficient – with relatively good power – needs to fulfill the assumption about normal distribution. In other cases only non-parametric tests can be used. This article presents a possibility and advantages of permutation tests with the discussion about proposed test statistics. The power of proposed tests was estimated on the basis of Monte Carlo experiments. The investigations were carried out for real data – a sample of refinery process parameters, where the indication of changes in correlation, even for sample with small size is very important. It creates an opportunity to react to changes and update statistical models quickly and keep acceptable quality of prediction

Opis:
In the paper, we assess the accuracy of the Monte Carlo continuous energy burnup code (MCB) in predicting final concentrations of major actinides in the spent nuclear fuel from commercial PWR. The Ohi-2 PWR irradiation experiment was chosen for the numerical reconstruction due to the availability of the final concentrations for eleven major actinides including five uranium isotopes (U-232, U-234, U-235, U-236, U-238) and six plutonium isotopes (Pu-236, Pu-238, Pu-239, Pu-240, Pu-241, Pu-242). The main results were presented as a calculated-to-experimental ratio (C/E) for measured and calculated final actinide concentrations. The good agreement in the range of ±5% was obtained for 78% C/E factors (43 out of 55). The MCB modeling shows significant improvement compared with the results of previous studies conducted on the Ohi-2 experiment, which proves the reliability and accuracy of the developed methodology.

Opis:
In the existent world of continuous production systems, strong attention has been waged to anonymous risk that probably generates significant apprehension. The forecast for net present value is extremely important for any production plant. The objective of this paper is to implement Monte Carlo simulation technique for perceiving the impact of risk and uncertainty in prediction and forecasting company’s profitability. The production unit under study is interested to make the initial investment by installing an additional spray dryer plant. The expressive values acquied from the Monte Carlo technique established a range of certain results. The expected net present value of the cash flow is $14,605, hence the frequency chart outcomes confirmed that there is the highest level of certainty that the company will achieve its target. To forecast the net present value for the next period, the results confirmed that there are 50.73% chances of achieving the outcomes. Considering the minimum and maximum values at 80% certainty level, it was observed that 80% chances exist that expected outcomes will be between $5,830 and $22,587. The model’s sensitivity results validated that cash inflows had a greater sensitivity level of 21.1% and the cash inflows for the next year as 19.7%. Cumulative frequency distribution confirmed that the probability to achieve a maximum value of $23,520 is 90 % and for the value of $6,244 it is about 10 %. These validations suggested that controlling the expenditures, the company’s outflows can also be controlled definitely.

Opis:
Artificial ground freezing (AGF) systems are susceptible to uncertain parameters highly affecting their performance. Particularly, selective artificial ground freezing (S-AGF) systems involve several uncertain operational conditions. In this study, uncertainty analysis is conducted to investigate four operational parameters: 1) coolant inlet temperature, 2) coolant flow rate, 3) pipes emissivity, and 4) pipes eccentricity. A reduced-order model developed and validated in our previous work for field-scale applications is exploited to simulate a total of 5,000 cases. The uncertain operational parameters are set according to Monte Carlo analysis based on field observations of a field-scale freeze-pipe in the mining industry extending to 460 m below the ground surface. The results indicate that the freezing time can range between 270 and 350 days with an average of 310 days, whereas the cooling load per one freeze-pipe ranges from 90 to 160 MWh, with an average of 129 MWh. Furthermore, it is observed that the freezing time and energy consumed are mostly dominated by the coolant inlet temperature, while energy dissipated in the passive zone (where ground freezing is not needed) is mostly affected by pipes emissivity. Overall, the conclusions of this study provide useful estimations for engineers and practitioners in the AGF industry.
