Optimal Choice Of Recovery Technologies For Waste Lubricating Oils 57_14.pdf

A technique for an optimal choice of technologies set for recovering the performance properties of waste lubricating oils based on dynamic programming has been described in the article. Each variant of technological operation has a different productivity and costs, also it is characterized by a specific sequence of quality indicator changes for the oil recovery. Authors make a choice of the sequence and content of technological operations which provide the given quality indicators for the recovery of oil performance properties with the lowest cost of labor input and implementation time. A composite indicator has been adopted as a target function which considers the productivity and cost for the oil recovery. The technological process is considered as a changing function of present value for the technological operation in case of its constant implementation time and function of time operation changing in case of its constant present value. According to dynamic programming methods, the use of the system of data on each technological operation stage allows obtaining the recurrent equations to determine the optimal technology with minimal present costs and time for the technological operations implementation. The solution of obtained equations results in the data array. The data analysis allows choosing the technological operations with optimal balance between its implementation time and present costs. The proposed optimization technique can be used in the development of the technological processes of any other type of production.

Recovery technology, technological operation, optimization, dynamic programming method.

Developing the Model for Improving the Vehicles’ Operating Characteristics 54_11.pdf

The process of developing the model to improve vehicles’ operating characteristics has been described in the article. The model development is based on the interrelation and reciprocal influence of the main elements of the vehicle. Since the internal combustion engine is the source of energy and the driving force, its characteristics has a direct influence on the operating properties of the vehicle. In its turn, they mainly depend on the nature of the working process course and engine parameters. Therefore, a change in the technical and operational characteristics of the engine will entail a change in the operating characteristics of the vehicle in which it has been installed. The information model of the engine parameters’ influence on operating characteristics of the vehicle allows us to find that, for certain operating time and fixed values of operating modes, an improvement of operating characteristics of the vehicle can be made by changing the technical and operational characteristics of the engine. At the same time, considering the operating model of the internal combustion engine in a form of a specific multidimensional and multilevel system, it was found that the working process in the engine and the design parameters of its mechanisms have the greatest influence on the change in engine parameters. The main work process takes place in the engine cylinder, so the parts of the cylinder-piston group will have the greatest influence on the change in the output parameters of the engine. The use of mathematical modeling in solving this problem allows us to develop a concept of improving the vehicle’s operating characteristics, to optimize the process of choosing the ways to modernize the engine and the vehicle.

Vehicle’s operating characteristics, information model, multidimensional and multilevel system.
