47. SENSITIVITY ANALYSIS

One of the tasks of project analysis is determining the sensitivity of performance indicators to changes in various parameters.

It is necessary to analyze the stability of the project to possible changes in both the economic situation as a whole (changes in the structure and rates of inflation, increased delay in payments) and internal indicators of the project (changes in sales volumes, product prices). Such an analysis is called a sensitivity analysis.

The wider the range of parameters in which the performance indicators remain within acceptable values, the higher the "margin of safety" of the project, the better it is protected from fluctuations of various factors that affect the results of the project.

Investigation of the sensitivity of performance indicators to changes in the discount rate allows you to determine the stability of the project in relation to fluctuations in the financial market and possible changes in macroeconomic operating conditions.

For sensitivity analysis, you need to:

▪ select the main indicators (NPV, IRR, FV, etc.), changes in which will significantly affect the project flows;

▪ analyze when the level of factors changes (changes in revenue, cost, salary costs, taxes, etc.), which indicator will be most sensitive to these changes and which factor has the greatest impact on the model;

▪ check the sensitivity of the selected indicator with the probability of deviations of the first (the probability that the factor will change, i.e. it will become larger, smaller or remain planned) and second levels (if the factor nevertheless turns out to be below the planned level, then with a probability of 60% the deviation will not more than 10%).

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

Energy from space for Starship 08.05.2024

Producing solar energy in space is becoming more feasible with the advent of new technologies and the development of space programs. The head of the startup Virtus Solis shared his vision of using SpaceX's Starship to create orbital power plants capable of powering the Earth. Startup Virtus Solis has unveiled an ambitious project to create orbital power plants using SpaceX's Starship. This idea could significantly change the field of solar energy production, making it more accessible and cheaper. The core of the startup's plan is to reduce the cost of launching satellites into space using Starship. This technological breakthrough is expected to make solar energy production in space more competitive with traditional energy sources. Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

Android devices last longer 27.11.2011

Many are familiar with the "appetites" of the Android mobile operating system: with all services turned on, the battery charge is consumed in a matter of hours.

This shortcoming decided to correct the Chinese company Huawei. Her new smartphone called Honor has an impressive battery capacity of 1900 mAh. At the same time, this did not greatly affect the weight of the device - it is 140 grams. The thickness of Honor is also at the level of the best models of competitors - 10,9 mm.

The smartphone is equipped with a four-inch screen, a processor with a clock speed of 1,4 GHz and a camera with a resolution of eight megapixels.
