In this paper, the microprism reflective structure is optimized by theoretical research and simulation calculations, and based on the current technology of V-shaped diamond blade manufacturing mode, an improved microprism retroreflective material is designed. By adjusting the intensity distribution and angle of the light cone, we can control the style of light cone which is formed by the reflected light for optimal reflective effect. The microprism reflective structure contains the positive unit and negative unit. The negative unit relative to the positive unit is rotated 60° for producing phase superposition to reduce the non-uniform of the material orientation. Cutting along a straight line by V-shaped diamond blade, the technology creates a plurality of higher-precision and smaller reflective elements and enhances the retroreflective performance. Meanwhile, the overall processing technology which reduces labor force greatly is beneficial to the cost control and highly practical during the fabrication process. Keywords: microprism retroreflective material, improvement and optimization

In modern conditions for Kazakhstan, it becomes important to choose a development model that would be the most optimal and effective. When developing a model of economic policy, special attention should be paid to the choice of a system of indicators that could adequately describe macroeconomic processes as a whole and their interconnections. At the same time, economists argue that the implementation of the model approach can become the basis for strategic decisions only in a stable economic situation and when in the period under review the change in the cost structure of GDP is not distorted by high inflation. Therefore, in modern conditions of economic development, in our opinion, it is of interest to study the relationship between economic growth and the level of current and threshold inflation. This study substantiates the role of the threshold inflation level and proposes an equation of the functional dependence of this indicator on the main economic indicators. The necessary conditions for the implementation of the inflation targeting regime are disclosed. It is concluded that in conditions of commodity dependence, new effective monetary policy instruments are required.

In the concurrent system, each node avails as a packet over the network depends on the length of the node. The length of the node generated through straight line routing algorithm. The cost of routing depends on the shortest path routing algorithm. The shortest path is determined by the cost of a distance from one node to another over the network. The capacity of a network is balanced and maintained by the straight routing. The traffic and cost is balanced over the network by using the algorithms.

The article presents the results of theoretical research to achieve the maximum effect in determination of the economically feasible level of buildings thermal protection. It must be optimal both thermally and economically, an indicator of which there are the costs. Graphical and analytical dependences are given. The research results substantiate the maximum effect when different thermal insulating materials are used. The aim is to increase the efficiency of energy saving measures, reduce their cost by optimizing the cost of thermal energy and insulating materials, determining the optimization criteria and justification for choice the optimal insulating material and its thickness, and determining the optimal thermal resistance, identifying ways to improve energy efficiency and substantiation of the calculation method. One of the most common thermal renovation measures, namely insulation of external walls, is considered. An economic assessment has been conducted, which is an important factor in a certain energy-saving proposition. The solution of the problem is presented, which includes two stages. The result of the first stage is the selection of the optimal heat-insulating material. The second stage is a substantiation of economically expedient thickness of the heatinsulating material. The obtained results make it possible to increase the efficiency of energy saving in thermal renovation of buildings taking into account both energy and economic aspects. In this paper the results of mathematical provement of such factor importance as the thermally conductive cost of the heat-insulating material at their thickness optimization are presented. Determining for the establishment of the normative thermal resistance in the future is the ratio of the cost of thermal energy to the thermal conductivity of the insulating material.

This paper, which was presented at a meeting of the Institute in London on 2o May 1981, with Captain R. Maybourn in the Chair, describes some studies of the conflicts arising between a multiplicity of aircraft in straight-line flight through a volume of airspace. Topics include the effect of coercing traffic to fly fixed routes, the direction from which a threat can be expected and the choice of alerting criterion for a groundbased advisory service or an airborne collision-warning system. There are some analogies, perhaps, with marine traffic problems.There exists, worldwide, a complex scheme for the segregation and control of various classes of air traffic. To fit into this scheme aircraft must make detours, horizontally and/or vertically, the cost of which in Europe alone must be at least £50M per annum. The cost of the rare failures in traffic management is higher still. To authors trained in electronic engineering it is therefore rather surprising that the published theory of air traffic management and control is still in a rather rudimentary form.

The logo of the Institute of Advanced Studies Kőszeg (iASK) refers to a more than 100 – year old, but still topical problem: how to join 9 dots arranged in a box - like square format with four straight lines without lifting the pen. The solution is only possible if, while moving the pen, we get out of the box. The box in fact does not exist, it is only a self imposed virtual limitation. Even more, the task can be solved also by using just one straight line, the only problem is that in order to achieve that the earth has to be circled twice. But why not circle the earth twice? We certainly have to consider the cost/benefit aspect as well but the lesson must not be forgotten: we shoud think twice before calling the solution of a task impossible

Abstract: Service-oriented manufacturing is a new manufacture mode. In order to solve the problem of resource allocation evaluation of service-oriented manufacturing enterprise, a Data Envelopment Analysis(DEA) mathematical model based on cost-benefit was constructed in this approach. The resource allocation evaluation problem was mapped to the cost-benefit analysis problem by using DEA, considering the characteristics of the service-oriented manufacturing mode, taking enterprise T as the example to analysis self-supporting allocation cost and cost-benefit value of service-oriented manufacturing enterprises to verify the applicability of the model. Finally, according to the recent five years’ situation of enterprise T, the optimization strategy of resource allocation was given.

This paper describes an information system that was architected to enable front end distributed intelligence in a real manufacturing environment. By distributing intelligence to the most robust components of the system, data can be preserved at the cost of very real-time information. In order for the system as a whole to function this way, each software component was fitted with watchdog agent and granted system level access to the operating system so that it could detect and repair itself and other tasks in the event of a failure. During the repair process, the appropriate data collection processes were granted a level of autonomy that preserved data integrity. The paper is quite practical and designed as a case study rather than a theoretical research paper, although the techniques and principles applied are the result of much study.

As a new development of cell manufacturing mode, virtual manufacturing cell (VMC) has complied with the new production organization requirements of current production efficiency and production flexibility improving synchronously, and it presents new characteristics in terms of cost accounting and cost control. Traditional cost methods present some shortcomings in VMC mode. For these situations, this paper discusses the advantages of activity-based costing (ABC) in VMC mode and improves traditional ABC to better meet the cost accounting requirements of VMC. Finally, an example is used to illustrate the basic use of the improved ABC in VMC mode.
