Concepts, substance and laws of dialectics
1) The world (the being, reality) exists objectively, i.e. irrespective of the will and conscience of a human being. 2) The world has not been created by anybody and cannot be destroyed by anybody. It exists and develops in accordance with natural laws. There are no supernatural forces in it. 3) The world is unique and there are no “extra-mundane” spheres and phenomena in it (standing “above the world” or “beyond the world”) that are absolutely abjoint from each other. Diverse objects and the phenomena of the reality represent various kinds of moving matter and energy. 4) The world is coherent and is in eternal, continuous movement, development. Objects of the reality interact with each other, influence upon each other. In the process of development qualitative changes in objects, including natural transitionfrom the lowest forms to the higher, take place. 5) Natural development of a matter through a number of natural steps (the inorganic/inanimate nature/abiocoen/ – life – society) has led to the origin of human being, intellect, conscience. The crucial role in the segregation of human being from animality and the formation of its conscience was played by labor, its social nature, transition of the human being’s animal ancestors to regular productionand application of instruments of labor. 6) Society being the higher step of development of substance includes all lowest forms and levels (mechanical, physical, chemical, biological) on the basis of which it has arisen, but is not reduced to them only. It exists and develops on the basis of social laws which qualitatively differ from the laws of the lowest forms. The paramount law of social development is the determinant role of production in the life of the society. Mode of production of material life conditions social, political and spiritual processes of life in general. 7) The world is knowable. Human knowledge is unlimited by nature, but is limited historically at each stage of its development and for each separate individual. The criterion for the verity of thinking and cognition is public practice. In recent years the need arose for the formation of higher form of dialectic-materialistic outlook - “spiritual materialism”. Spiritual materialism extends the line of classical materialism in terms of recognition of objective character of existence, its cognoscibility, natural evolution of substance from the lowest to the higher forms, exclusion of notions of supernatural from scientific beliefs/notions, etc. At the same time, spiritual materialism overcomes absolutization of superiority of material over the spiritual, contraposition and discontinuity of these fundamentals inherent in the former forms of materialism, and directs towards the revelation of their unity, complex interrelation, interpenetration, definite fixation of relations in which the material and spiritual determine each other in the process of functioning and development of objects. Threemain laws of dialectics are: the lawof transition from quantity to quality,the law of unity and conflict of oppositesand the lawof negation of negation. There is more to it than these three major laws in dialectics. Abscque hoc, there are a number of other dialectic lawsconcretizing and supplementing organic laws of dialectics expressed in categories “substance and phenomenon”, “content and form”, “contingency and necessity”, “cause and effect”, “possibility and reality”, “individual, special and general”, the dialectic triad: thesis, antithesis andsynthesis. Categories and laws of dialectics exist within a certain system in which the substance/essence of dialectics properis expressed.
Analysis of the decision-making methods without use of numerical values of probability (exemplificative of the investment projects).
In practice situations are often found when it is difficult enough to estimate the value of probability of an event. In such cases methods are often times applied which do not involve using numericalvalues of probabilities: maximax – maximization of the maximumresult of the project; maximin – maximization of the minimum result of the project; minimax –minimization of maximum losses; compromise – Gurvitz’s criterion: weighing of minimum andmaximum results of the project. For decision-making on realization of investment projects a matrix is built. Matrix columns correspond to the possible states of nature, i.e. situations which are beyond of control of the head of an enterprise. Lines of the matrix correspond to possible alternatives of realization of the investment project – strategies which may be chosen by the director. The matrix cells specify the results of each strategy for each state of nature. Example: The enterprise analyzes the investment civil-engineering design of a line for the production of new kind of product. There are two possibilities: the construction of a high power capacity line or to construct low power line. Net present value of the project depends on the demand for production, whereas the exact volume of demand is unknown, however, it is known that there are three basic possibilities: absence of demand, average demand and great demand. The matrix cells (see table 1) show net present value of the project at a certain state of nature, provided that the enterprise will choose the appropriate strategy. The last line shows what strategy is optimumin each state of nature. The maximax decision would be to construct a high power capacity line: the maximum net present value will thus be 300 which correspond to the great demand situation. The maximum criterion reflects the position of the enterprise director – the optimist ignoring possible losses. The maximin decision, i.e. to construct a low power line: the minimum result of this strategy is the loss of 100 (which is better than possible loss of 200 in case of construction of a high power capacity line). The maximin criterion reflects the position of the director who is in no way disposed towards taking risk and is notable for his/her extreme pessimism. This criterion is quite useful in situations where risk is especially high (for example when the existence of an enterprise depends on the results of the investment project). Threat is determined by two components: possibilitiesand intention of the contestant.
Table 1. Example of construction of the matrix of strategy and states of nature for the investment project.
Strategy | State of nature : absence of demand | State of nature : medium demand | State of nature : great demand |
Construct a low power line | 100 | 150 | 150 |
Construct a high power capacity line | 200 | 200 | 300 |
Optimum strategy for the given state of nature |
Construct a low power line | Construct a high power capacity line | Construct a high power capacity line |
To apply the minimax criterion let us construct “a matrix of regrets” (see table 2). The cells of this matrix show the extent/value of “regret”, i.e the difference between actual and the best results which could have been achieved by the enterprise at the given state of nature. “Regret” shows what is being lost by the enterprise as a result ofmaking wrong decision. The minimax decision corresponds to the strategy, whereby the maximum regret is minimal. In our case of low power line maximum regret makes 150 (in great demand situation) and for a high power capacity line – 100 (in the absence of demand). As 100 <150, the minimax decision would be to construct a high power capacity line. The minimax criterion is oriented not so much towards actual as possible damages or loss of profit.
Table 2.
Example of structure of the “matrix of regrets” for minimax criterion
Strategy | State of nature: absence of demand | State of nature: medium demand | State of nature: great demand |
Construct a low power line | (-100) – (-100) =0 | 200 – 150=50 | 300 – 150=150 |
Construct a high power capacity line | (-100) – (-200) =100 | 200 – 200=0 | 300 – 300=0 |
Optimum strategy for the given state of nature |
Construct a low power line | Construct a high power capacity line | Construct a high power capacity line |
Gurvitz’s criterion consists in that minimum and maximum results of each strategy are assigned “weight”. Evaluation of result of each strategy equals to the sum of maximum and minimum results multiplied by corresponding weight.
Let’s assume that the weight of the minimum result is equal to 0.5, the weight of the maximum result equals to 0.5 as well (it is the probabilistic characteristic; in this case probability of onset of any option of events = 50 %, as far as we have 2 options : 50 % + 50 % = 100 %; if there will be 3 options, then the ratio can be 33,33 (%) for each or, for example, 20 %, 25 % and 55 %). Then the calculation for each strategy will be the following:
Low power line: 0.5 х (-100) + 0.5 х 150 = (-50) + 75 = 25;
