Fund Investment

Fund investment is a hot issue in today’s society. How to choose a project for investment is affected by many factors. In view of this problem, this paper starts from the granular computing point of view and combines the multigranulation rough set decision-making method to construct a fund investment decision information system; then, the fund investment decision information system is reduced under different thresholds, and the decision rules are extracted through reduction. And from the aspects of decision accuracy and rule accuracy, the rules are analyzed. Finally, decision rules are used to give the decision of the fund investment project. This study provides a new approach to fund management.

Interval Valued

As a further extension of the fuzzy set and the intuitive fuzzy set, the interval-valued intuitive fuzzy set (IIFS) is a more effective tool to deal with uncertain problems. However, the classical rough set is based on the equivalence relation, which do not apply to the IIFS. In this paper, we combine the IIFS with the ordered information system to obtain the interval-valued intuitive fuzzy ordered information system (IIFOIS). On this basis, three types of multiple granulation rough set models based on the dominance relation are established to effectively overcome the limitation mentioned above, which belongs to the interdisciplinary subject of information theory in mathematics and pattern recognition. First, for an IIFOIS, we put forward a multiple granulation rough set (MGRS) model from two completely symmetry positions, which are optimistic and pessimistic, respectively. Furthermore, we discuss the approximation representation and a few essential characteristics for the target concept, besides several significant rough measures about two kinds of MGRS symmetry models are discussed. Furthermore, a more general MGRS model named the generalized MGRS (GMGRS) model is proposed in an IIFOIS, and some important properties and rough measures are also investigated. Finally, the relationships and differences between the single granulation rough set and the three types of MGRS are discussed carefully by comparing the rough measures between them in an IIFOIS. In order to better utilize the theory to realistic problems, an actual case shows the methods of MGRS models in an IIFOIS is given in this paper.

Variable precision rough set (VPRS) based on dominance relation is an extension of traditional rough set by which can handle preference-ordered information flexibly. This paper focuses on the maintenance of approximations in dominance based VPRS when the objects in an information system vary over time. The incremental updating principles are given as inserting or deleting an object, and some experimental evaluations validates the effectiveness of the proposed method.

 An approximation space (A-space) is the base of rough set theory and a fuzzy approximation space (FA-space) can be seen as an A-space under the fuzzy environment. A fuzzy probability approximation space (FPA-space) is obtained by putting probability distribution into an FA-space. In this way, it combines three types of uncertainty (i.e., fuzziness, probability and roughness). This article is devoted to measuring the uncertainty for an FPA-space. A fuzzy relation matrix is first proposed by introducing the probability into a given fuzzy relation matrix, and on this basis, it is expanded to an FA-space. Then, granularity measurement for an FPA-space is investigated. Next, information entropy measurement and rough entropy measurement for an FPA-space are proposed. Moreover, information amount in an FPA-space is considered. Finally, a numerical example is given to verify the feasibility of the proposed measures, and the effectiveness analysis is carried out from the point of view of statistics. Since three types of important theories (i.e., fuzzy set theory, probability theory and rough set theory) are clustered in an FPA-space, the obtained results may be useful for dealing with practice problems with a sort of uncertainty.

Tamantirto village, Kasihan, Bantul is an area which is positively responsive in terms of dealing with the Covid-19 pandemic. The citizens’ response is not only showed by implementing health protocol and entrances shutdown during the pandemic, but is also empowered by the consciousness of knowledge and experience transfer about pandemic for the next generation. Through the existing village’s information system, they offer a collaboration to lecturer of Indonesian Language and Letter Study Program of FIB UGM in order to conduct feature writing training about citizens’ point of view and experience during the pandemic. The training is held in two methods. The first is direct training method with power point elaborating the definition, type, example, and writing technique and feature editing. The second one is writing guidance using WA group where the participants can send their work to the group chat and then the trainer give feedback for the document. The training produce 21 feature documents which are averagely elaborate the participants’ profession regarding with the pandemic. Most of the documents are written with argumentative paragraph instead of narrating their experience during the pandemic like the common feature which is tend to be narrative. ===== Desa Tamantirto, Kasihan, Bantul merupakan wilayah yang tanggap dalam menghadapi pandemi Covid-19. Ketanggapan warga tidak hanya ditunjukkan melalui penerapan protokal kesehatan dan penutupan sejumlah pintu gang ketika masa pandemi, tetapi juga didukung pada kesadaran akan pentingnya pewarisan pengetahuan dan pengalaman seputar pandemi kepada generasi mendatang. Melalui Tim Sistem Informasi Desa yang mereka miliki, mereka mengajak kerja sama dengan dosen Prodi Bahasa dan Sastra Indonesia FIB UGM untuk mengadakan kegiatan pelatihan penulisan feature seputar pandangan dan pengalaman warga selama pandemi. Pelatihan diselenggarakan dengan dua cara. Pertama, pelatihan secara langsung dengan media power point yang menguraikan definisi, jenis, contoh, dan teknik penulisan serta penyuntingan feature. Kedua, bimbingan penulisan melalui WA Grup ketika peserta mengirimkan karyanya ke grup WA dan narasumber memberikan masukan terhadap naskah tersebut. Pelatihan menghasilkan 21 naskah feature yang rata-rata menguraikan profesi para peserta dan mengaitkannya dengan pandemi. Sebagian besar naskah masih lebih banyak diisi dengan paragrat argumentatif dibandingkan menarasikan pengalaman selama pandemi sebagaimana layaknya feature yang cenderung naratif.

Hardware is a computer that can be seen and touched in person. Hardware is used to support student work and learning processes. The hardware should always be in good shape. If any damage should be done quickly. The benefits of this study provide a viable level of data against hardware tools. The purpose of this study determines that hardware that is worth using quickly and precisely so easily can be repaired and replaced. Hard-processed action consists of 12 projectors, 2 units of access point, 6 units of monitors, and 20 CPU units. To see the level of appropriateness regarding hard drives requires a rough set algorithm with that stage: information system; Decision system; Equivalency class; Discernibility matrix; Discernibility Matrix module D; Reduction; Generate Rules. The results of the 40 devices of study STMIK Indonesia Padang subtract college have 10 rules of policy on whether the hardware is still viable, repaired or replaced. So using a rough set algorithm is particularly appropriate to apply in a verifiable level of accuracy to fast and precise hardware.
