What models of managerial decision-making exist
Methods for modeling and optimizing solutions
In the process of resolving complex problems, with the goal of strengthening the ability of managers to make informed and objective decisions can be used various scientific methods for their design and optimization, the Arsenal which can be divided into two main classes:
• methods of modeling;
• methods of expert evaluation.
The methods of modeling (also called methods of studying operations) are based on the use of mathematical models to solve the most frequently encountered directional problems.
The development and optimization of the solution of a particular problem by modeling methods is a rather complicated procedure, which can be represented by the following major stages:
• setting the task;
• determination of the criterion of effectiveness of the transaction being analyzed;
• quantitative measurement of the factors affecting the operation;
• Construction of the mathematical model of the object under study (operation);
• quantitative solution of the model and finding the optimal solution;
• Verification of the adequacy of the model and the found solution of the analyzed situation;
• updating and updating the model. The number of all possible specific models is almost as great, as well as the number of problems for which they are developed.
Models of game theory
Most business transactions can be considered as actions committed in the face of opposition. The opposition should include such factors as collision, fire, theft, strike, violation of contractual obligations, etc. However, the most grassroots event counter is the competition. Therefore, one of the most important conditions on which depends the success of the organization, is competitive. Clearly the ability to predict the actions of competitors is a significant advantage for any business organization. Making a decision, you should choose the alternative that allows to reduce the degree of counteraction, which, in turn, will reduce the risk.
This opportunity provides the Manager with game theory, mathematical models which are encouraged to analyze possible alternatives of their actions taking into account possible retaliatory actions of competitors.
Models of queuing theory
Models of queue theory (or optimal maintenance) are used to find the optimal number of service channels at a certain level of demand in them.
Models of inventory management
Any organization should maintain a certain level of reserves of its resources in order to avoid protractions or breaks in technological processes and the sale of goods or services.
The models of control of seizures make it possible to find the optimal solution, that is, the level of the charge that minimizes the costs of its creation and maintenance at a given level of continuous production processes.
Linear Programming Models
These models are used to find the optimal solution in the situation of distribution of scarce resources in the presence of competing needs.
A large part designed for practical application of optimization models are reduced to linear programming problems. However, given the nature of the analyzed operations and established forms of dependence factors can be applied to other types of models with nonlinear forms of dependence of the result of the operation from the main factors of the model of nonlinear programming
