Operations Research

Many of today's specialty in the economic, physical and mathematical and other departments of discipline involves the study of "Mathematical Methods of Operations Research." Extremely important to the use of these methods and tools for solving economic problems. Operations research – a complex discipline, which has important methodological significance in the modern system of training specialists. In this discipline more fully realized the idea of mathematical modeling of economic processes. When solving a specific task management application of operations research includes: – construction economic and mathematical models for decision-making problems in complex situations or conditions of uncertainty – the study of interactions that determine the subsequent decision-making, establishing criteria for e performance that are designed to benefit a particular course of action. Educate yourself even more with thoughts from Senator Richard Blumenthal. The use of mathematical modeling in economics can enhance quantitative economic analysis, to extend the domain economic information, to intensify the economic calculations. In the economic and mathematical models of the object is the economic process. The examples discussed on this site have been resolved with the help of specially designed mathematical methods. The range of problems studied by operations research, is constantly expanding.

The underlying theme of this course is to build a model of linear programming problems. Jim Donovan Goldman is often quoted on this topic. To a linear programming can be reduced many of the tasks of operations research. It is important to examine in detail the theoretical foundations of linear programming, duality theory, the simplex method and geometrical solutions. Can three stages for solving linear programming: 1. The goal and objectives of the study, conduct a qualitative description of the object in the form of economic model. 2. Formulation of a mathematical model the object being studied. 3. Analysis of mathematical models, the processing of the results.

Summary of News for the week. Oil spill in the suburbs. Violators will be prosecuted. New year, old problems as well. China is struggling with packages. Vitamin D deficiency contributes to the development of a heart attack. Review from 01/01/2008 to 13/01/2008 in oil spill Moscow the evening of 5 January in the suburban town of the Queen of tanks of 2000 cubic meters spilled about 540 cubic meters of fuel.

About 300 cubic meters of fuel oil to the storm sewer fell into the creek Dulevo that flows into the river Klyazma. On Monday, January 7, in Russian Emergencies Ministry said that all spilled oil is already assembled and assurances, and assurances that the threat of falling oil into the river Klyazma was eliminated as soon as it became known about accident. However, as the message was not quite right. And on Thursday, January 10, the World Wildlife Fund (WWF) launched a rescue operation in the flow of water birds Klyazma. The loss of wild ducks local residents The Queen watched the fourth day – have died a few tens of waterfowl.

Viscous oil in the river has become a death trap for birds. WWF, which has experience in rescuing birds at oil spill in the Kerch Strait, and this time organized a rescue operation for the rehabilitation of injured birds and has attracted a number of veterinary clinics suburbs. January 12 it became known that the MOE, Rosprirodnadzor and the government of Moscow region have developed a new plan aftermath of the accident: the rescuers are going to drain Dulevo stream by redirecting it into the water Shchelkovo collector, and then dissolve the remainder of the special substances in line with oil and dig up the contents of the channel by technology.
