This article is dedicated to the analysis and generalization of the well-known task of operation synchronization in assembly shops and its extension to the robot complexes in processing shops. The verbal defi nition of this generalized problem specifying its relation with the "task of stone heap" is done. An economic-mathematic model of this task improved by the author, the method of its solution, and the fl ow block of the appropriate algorithm is suggested.
The role of computer mathematics systems (CMS) as a technological tool of modern mathematical courses for students of economics is reviewed. The advantage of CMS usage is marked. The functions of CMS for studies of separate courses of mathematical are demonstrated with the economic-mathematical model of multivariate analysis as an example.
The article considers the interaction mechanism between the official (legal) and illegal (shadow) economies described by a planar dynamic model, namely a system of two nonlinear ordinary differential equations. The authors obtained the analytical solution to these model equations, as well as formulated the conditions of coexistence of legal and hidden economies.
Smoking is a problem, bringing signifi cant social and economic costs to Russiansociety. However, ratifi cation of the World health organization Framework conventionon tobacco control makes it possible to improve Russian legislation accordingto the international standards. So, I describe some measures that should be taken bythe Russian authorities in the nearest future, and I examine their effi ciency. By studyingthe international evidence I analyze the impact of the smoke-free areas, advertisementand sponsorship bans, tax increases, etc. on the prevalence of smoking, cigaretteconsumption and some other indicators. I also investigate the obstacles confrontingthe Russian authorities when they introduce new policy measures and the public attitudetowards these measures. I conclude that there is a number of easy-to-implementanti-smoking activities that need no fi nancial resources but only a political will.
