Entrepreneurship Interest by Solely Micro, Small and Medium Enterprises During Covid-19 Outbreak

The purpose of this article is to discuss in more detail both internal and external factors causing entrepreneurship interest as a solely or a small group enterprise. The purpose is also to find out 1). The Interest of the students in Sekolah Tinggi Ilmu Ekonomi Sampit ( The Institute of Economic Sciences ) Sampit in becoming Enterpreneurs 2). What are the factors that causes the students’ interests in becoming Enterpreneurs ?. Methodology of this research is descriptive qualitative. The qualitative approach is used to examine interests in becoming Entrepreneurships as well as the factors.Data collection for this research is through study literatures, field observation, questionnaires and deep interviews. The finding of this research shows low interest of being entreprenurship as the effect of covid 19 outbreak. The external factors that cause low interest of being a solely entrepreneur is shown through the procentage , it is less than 18% . While average procentage of the internal factors is at 9%-18%. The original value of this article is that to increase interest of being solely micro, small and medium enterprises should be supported with the change of learning system in which 60% practices rathen than theory in this Covid-19 pandemic. The implementation of theory in the real situation as an enterpreneurs.

Non-submodular model for group profit maximization problem in social networks

In social networks, there exist many kinds of groups in which people may have the same interests, hobbies, or political orientation. Sometimes, group decisions are made by simply majority, which means that most of the users in this group reach an agreement, such as US Presidential Elections. A group is called activated if $$\beta$$ β percent of users are influenced in the group. Enterprise will gain income from all influenced groups. Simultaneously, to propagate influence, enterprise needs pay advertisement diffusion cost. Group profit maximization (GPM) problem aims to pick k seeds to maximize the expected profit that considers the benefit of influenced groups with the diffusion cost. GPM is proved to be NP-hard and the objective function is proved to be neither submodular nor supermodular. An upper bound and a lower bound which are difference of two submodular functions are designed. We propose a submodular–modular algorithm (SMA) to solve the difference of two submodular functions and SMA is shown to converge to a local optimal. We present an randomized algorithm based on weighted group coverage maximization for GPM and apply sandwich framework to get theoretical results. Our experiments verify the efficiency of our methods.

Development Status of Cloud Manufacturing in China

Facing technological innovation and structural transformation challenges in depth development of China’s manufacturing industry, the concept of cloud manufacturing (CMfg) was proposed and got government’s support. This paper reviews the development status of CMfg in China. On the one hand, a number of research institutions studied systematically on theories and key technologies of CMfg, such as application patterns and platform architectures, resource matching, service composition and sharing, manufacturing cloud integrated management, etc. And on the other hand, some cloud manufacturing service platforms were build and applied in small and medium-sized enterprises and group enterprises, such as group enterprise CMfg service platform for the complicated aerospace products, CMfg service platform of aerospace technology group, group enterprise CMfg service platform for manufacturing and management, cloud application in growing enterprise management informatization, CMfg service platform for mould and flexible material industry, CMfg service platform for new product R&D of car parts, CMfg service platform for steel industry chain collaboration, CMfg service platform for mould industry in Ningbo, etc.
