The peculiarity of innovative products requires taking into account a large number of criteria that should be aggregated into generalized ones and building a convolution tree with qualitative, quantitative and fuzzy rules. The paper proposes a methodology for the optimal partitioning of criteria scales into generalized gradations for using combined methods of multicriteria analysis of alternatives. The transition to fewer criteria leads to a signifi cant increase in the dimension of the scales of generalized criteria. Scales have to be converted to new scales with fewer gradations. To solve the problem of minimizing the information loss occurring when converting the scales picked Bellman function and applied method of dynamic programming. Computational experiments have shown the effectiveness of the proposed approach.

AbstractWe study two closely related problems in the online selection of increasing subsequence. In the first problem, introduced by Samuels and Steele (Ann. Probab. 9(6):937–947, 1981), the objective is to maximise the length of a subsequence selected by a nonanticipating strategy from a random sample of given size $n$ n . In the dual problem, recently studied by Arlotto et al. (Random Struct. Algorithms 49:235–252, 2016), the objective is to minimise the expected time needed to choose an increasing subsequence of given length $k$ k from a sequence of infinite length. Developing a method based on the monotonicity of the dynamic programming equation, we derive the two-term asymptotic expansions for the optimal values, with $O(1)$ O ( 1 ) remainder in the first problem and $O(k)$ O ( k ) in the second. Settling a conjecture in Arlotto et al. (Random Struct. Algorithms 52:41–53, 2018), we also design selection strategies to achieve optimality within these bounds, that are, in a sense, best possible.

Today modular construction is gaining popularity in the arrangement of production facilities. The purpose of the research is the theoretical substantiation of the choice of the optimal thickness of thermal insulation for external protections of modular buildings taking into account the evaluation criteria based on the method of hierarchy analysis. The article reflects the possibility of using modular buildings for residential and public needs. Given the peculiarities of the use of thermal insulation materials, such structures are erected in a short period of time due to the use of ready-made modules. It is also proposed to use multicriteria analysis to compare different thicknesses of thermal insulation of a modular building. The obtained results are presented in the form of petal diagrams and diagrams of global priorities, which made it possible to make an in-depth assessment of several thicknesses of thermal insulation. When conducting theoretical research, it should be noted that the importance of each of the criteria was taken into account for the selection of thermal insulation. An expert assessment was performed to determine the thickness of thermal insulation, which can be used for lightweight prefabricated structures of modular buildings. As a result of research, it was found that the most suitable thermal insulation material is polyurethane.

The application of rationalized thinning technology in beech coppice stands was studied. Three basic methods of thinning: schematic, selection and combined method were analyzed. In the framework of each of the above thinning methods, different thinning varieties were designed, differing by the degree of crosscutting, width of gathering lines and their distance. The applied method of felling and crosscutting is the whole tree method or log method, and the form of work organization (1M+1R). The felling and crosscutting are characterized by two key work operations: directed felling and manual collection of the felled wood material. Manual collection is made significantly easier by the correct selection of tree felling direction which in turn affects significantly the rationalization of the entire thinning process.

The method of dynamic programming has been considered, which is used in solving multiple problems in economics, on the example of using Bellman’s optimality principle for solving nonlinear programming problems. On a specific numerical example, the features of the solution have been shown in detail with all the calculations. The problem of optimal distribution of funds among enterprises for the expansion of production has been formulated, which would give the maximum total increase in output. The solution of the task has been presented in the case, when the number of enterprises is 3. It has been shown, that the Bellman optimality principle allows you solve applied problems of cost forecasting with obtaining the optimal solution-maximum profit at minimum costs.

Human Being’s life is the most significant asset and life-insurance is the most significant sort of insurance which gives financial protection to theindividualhimself/herself and to his family at the hour of dubious dangers or harm. Life insurance gives both safety and protection to people and furthermore encourages investment funds among individuals. The present exploratory based investigation was chosen with a target to analyze those factors which impact client’s strategy purchasing choice and furthermore examine the inclinations of clients while making decision about insurance policy investment. Different insurance-related factors have been examined in the paper. Also, the said study has been conducted to know the satisfaction level of the clients and also to know the benefit they have been receiving from the company (if any). The information for the research has been gathered from primary data. The study zone is restricted to Maharashtra state and the test sample is 30 investors. The hypotheses have been based on the basis of demographic and the factors related to the insurance-based preference.factors and tested the same with the help of statistical tool T-test. The analyzed data had been produced in the form of a tables and graphs/charts. Insurance agencies should spread more awareness about life insurance, a decrease in the premium amount, and giving more attention to need-based innovative products are a portion of the recommendations which I would suggest. The paper closes with the segment that factors of the individuals play a significant and essential role in choosing the purchase of insurance policies.

Main Strategy

Food waste (FW) has a high potential for use in biological processes such as anaerobic digestion (AD), especially due to its high content of biodegradable organic matter. To inoculate the reactors, sludge is usually used. The sludge should ideally have good sedimentation and specific methanogenic activity (SMA), which is typical for granular sludge. However, in a Latin American context, the most available and accessible sludges are flocculants with low sedimentation and SMA. Applying technological surveillance between 1975 and 2017, using multicriteria analysis techniques such as analytical hierarchy process (AHP), and consulting with international and national experts, we observed that there were few studies, compared to published studies on the substrates that focused on improving inoculum quality through conditioning to improve its characteristics and maximize methane production. The inoculum-conditioning methodologies identified were grouped into five categories, being the main strategy the addition of nutrients followed by anaerobic digestion with an easily degradable substrate. However, extension of technological surveillance is recommended by incorporating the results published from significant events in the field of anaerobic digestion, such as the Latin American Workshop and Symposium on Anaerobic Digestion and the World Congress on Anaerobic Digestion.

Robots have rapidly become key elements to improve general performances of the existent products, to add up new supplementary characteristics or even in view of creating new products that were impossible to create prior to this research. This paper presents a measuring system with optical device in view of determining velocity variation on the investigated axe of the maximum velocity and acceleration or of their variation in dynamic circumstance. The advanced research of precision parameters is a technical necessity, which leads to the selection of linear actuators according to the conditions of usage. Has been made a measurements stand in order to determine these parameters, a stand equipped with laser ruler with a system of numeric acquisition of experimental data. By analyzing the measuring values presented in this paper it can be concluded that when the positioning precision in the target - point of an acting linear robot or when the trajectory precision is absolutely required, the obtained results must be taken into account. We can operate these appropriate corrections in the system of dynamic programming of the robot.

Dynamic programming algorithm is the classic method in distribution of plant loads. The traditional calculation method of dynamic programming is easy to make the calculation take too long time. This paper proposes two modiefied methods of dynamic programming, namely, dynamic programming in progressive structure and dynamic programming in progressive step-size. What is more, these two methods are combined to a new hybrid method. And these three methods and conventional dynamic programming are applied to the distribution of thermal power plant load to verify. The results of modiefied methods contrast with the conventional method show the modiefied methods reduce the calculation time and alleviate the curse of dimensionality effectively, ensuring the accuracy of calculation.
