A study of uncertain multi-objective nonlinear programming problems for rough intervals

In real conditions, the parameters of multi-objective nonlinear programming (MONLP) problem models can’t be determined exactly. Hence in this paper, we concerned with studying the uncertainty of MONLP problems. We propose algorithms to solve rough and fully-rough-interval multi-objective nonlinear programming (RIMONLP and FRIMONLP) problems, to determine optimal rough solutions value and rough decision variables, where all coefficients and decision variables in the objective functions and constraints are rough intervals (RIs). For the RIMONLP and FRIMONLP problems solving methodology are presented using the weighting method and slice-sum method with Kuhn-Tucker conditions, We will structure two nonlinear programming (NLP) problems. In the first one of this NLP problem, all of its variables and coefficients are the lower approximation (LAI) it’s RIs. The second NLP problems are upper approximation intervals (UAI) of RIs. Subsequently, both NLP problems are sliced into two crisp nonlinear problems. NLP is utilized because numerous real systems are inherently nonlinear. Also, rough intervals are so important for dealing with uncertainty and inaccurate data in decision-making (DM) problems. The suggested algorithms enable us to the optimal solutions in the largest range of possible solution. Finally, Illustrative examples of the results are given.

Perancangan Sistem Data Hasil Belajar Murid SMA Islam Said Na’um Berbasis Java

SMAI Said Na'um is a senior secondary education institution in the Jakarta area. The system at this school has not used a computerized system optimally so it has several problems. The problems in Said Na'um SMAI include recording values using paper files which take a very long time. Lack of storage media, the data search process takes a little time. The information received is currently less fast and less accurate. Often there are data errors or inaccurate data in making reports. Data storage that is still in the form of physical files can cause damage to data. Based on this information, the research carried out aims to create an information system for learning assessment for students of Said Na'um Senior High School, Central Jakarta. This research was conducted by creating a data system on student learning outcomes at Said Na'um Islamic Senior High School using a Java-based programming language.

Integrated Data-based Poverty Alleviation to Achieve SDGs

Poverty alleviation is not an easy job. Lack of coordination, inaccurate data, and slow information are factors leading to inappropriate decisions making. This research aims to learn in detail about the Integrated Social Welfare Database (ISWD) and how to use the ISWD for Poverty Programs. This research used a literature study approach through collecting, classifying, analyzing, visualizing, validating data, and drawing conclusions. The results of the research showed that the ISWD is an electronic data system containing social, economic, and demographic information in Indonesia which consists of 16 variables, namely: welfare status of households and individuals, education, health, employment, and primary information households covering the lowest share of 40% of the Indonesian population based on welfare states. The ISWD provides many benefits for the central government, regional governments in Indonesia, for example, supporting the analysis or the planning of poverty alleviation activities/programs, determining the target beneficiaries of social protection programs such as the Raskin Program, Jamkesmas, Assistance for Poor Students, Family Hope Program, and other programs managed by the regional government.

The development and implementation of an android-based saving and loan cooperative application

The savings and loans cooperative are a cooperative that has an important purpose in its reach and services, such as the Permata Ngijo Savings and Loans Cooperative. Activities within the cooperative itself include managing member data as well as savings and loan transactions. In systems that are still manual, such as Microsoft Excel, there is a risk of inaccurate data and takes a long time. This manual system is still less effective because the number of members and transactions continues to grow. Therefore, an application is needed as a more effective data processing and information system for members that is easier to access. This study aims to build an android-based savings and loan application using the hypertext preprocessor (PHP) programming language and my structured query language (MySQL) as data storage. Based on the android application that has been made, it shows that the black box functionality of the application runs as planned, the success rate for users reaches 90%.

Big Data Cleaning Model of Multi-Source Heterogeneous Power Grid Based On Machine Learning Classification Algorithm

Aiming at the low cleaning rate of the traditional multi-source heterogeneous power grid big data cleaning model, a multi-source heterogeneous power grid big data cleaning model based on machine learning classification algorithm is designed. By capturing high-quality multi-source heterogeneous power grid big data, weight labeling of data source importance measurement, data attributes and tuples, and constructing Tan network based on the idea of machine learning classification algorithm, the data probability value is finally used to complete the classification and cleaning of inaccurate data. Experiments show that the model based on machine learning classification algorithm can effectively improve the imprecise data cleaning rate compared with the traditional model to solve multi-source heterogeneous imprecise data cleaning.

A View on Pythagorean Fuzzy Contra 𝓖∗ Continuous Function

The new dimension of non-standard fuzzy sets called Pythagorean fuzzy sets which can handle the inaccurate data very strongly has been established in recent days. Even though intuitionistic fuzzy sets were generously used in decision making to handle the imprecise data the novelty and the voluminous of Pythagorean fuzzy environment gives motivation to use it in decision making process. The Pythagorean fuzzy topological spaces are the novel generalization of fuzzy topological spaces. Herein the concept of Pythagorean fuzzy contra 𝒢∗ continuous functions are explored. Interrelations have been studied elaborately for the defined functions using various examples.

Applying an active strategy for updating the potential properties of human-machine complexes in the processes of their design and operation

The analysis of the literature, reflecting the problem of potentiality in creating complex systems, including human-machine complexes (HMC) is carried out. On the basis of the generalized data, potentiality is defined as a fundamental property of objective reality, an integral part of the integrity structure of complex objects, which in the process of their functioning manifests itself in the form of engineering control situations unforeseen by the developers. A strategy for solving the problem of revealing the potential properties of HMC is considered from the viewpoint of comparing two approaches of “passive” and “active” strategies. A “passive” strategy means that the situations that arise unforeseen by the developers are taken into account by them, usually in the future when improving the technique. This approach does not consider the specifics of manifesting the systemic properties of the HMC and is incorrect from the methodological positions of modern systemic studies that assert the equivalence of subject-object relations in HMC. An “active” strategy for solving the problem under study includes a targeted search, disclosure and actualization of the potential properties of an object not only at the stages of its design and creation, but also at the stages of the exploitation in the joint activity of all professionals, namely developers, operators, engineering psychologists. This approach is based on forecasting and studying the potential properties of an exploited object on the basis of organizing a systematic and controlled cognitive process and studying the dynamics of changes in its operational characteristics under conditions of external factors that go beyond normal situations. It is concluded that to assess the characteristics of the HMC and determine the rational organization of its structures, it is necessary to develop an “active” strategy that allows using any type of information, including accurate data obtained on the basis of the deterministic methods of analysis, and inaccurate data obtained on the basis of an analysis of intuition, experience, considering all specialists’ values of judgments and figurative guesses, which will contribute to disclosing the potential of the created technical objects in the process of ergonomic support for their design and operation.

Analysis of IPv6 jumbogram packages transmission using jumbo frame in mikrotik-based tunneling

The validation and accuracy of internet protocol version 6 (IPv6) performance using jumbo frames is still not perfect, due to peer-to-peer connections testing within the same operating system and between operating systems. Therefore, inaccurate data test results. To mitigated, testing with a wider platform is recommended, a medium-scale network connection is proposed such as metropolitan area networks. In this works, a connection between computer devices connected by three proxy routers are made, with different IPv6 segments on each port. Then each computer device sends traffic data to each other using a traffic-generator application. The first test through three routers without tunnel connection is carried out as the first scenario to compare performance with tunnel-based testing. Three parameters have been used in this test, such as maximum transfer unit (MTU) 1500 bytes, MTU 400 bytes and MTU 9000 bytes. The results of the tests conducted show that the use of jumbo frames using a proxy is less effective, even though it produces a larger throughput when using the MTU 4000, but there is fragmentation in the packet passing through the proxy because the packet passing through the proxy is split into 1500 byte sizes.
