In this paper, a novel overmodulation strategy for space-rector PWM(SYPWM) inverters to utilize dc link voltage fully is presented. The proposed strategy uses the concept of SVPWM based on the zero sequence signal(offset voltage) injection principle. So, by modifying the pole voltage simply, the linear control of inverter output voltage over the whole overmodulation range can be achieved easily. The proposed strategy is so simple that its practical implementation is easy. The validity of the proposed strategy is confirmed by the experimental results.

The purpose of this paper is to suggest a supplier and buyer's pricing decision strategy model with discount-policy over a long-term replenishment contract in a supply chain environment by small and medium size manufacturing company. We assume that the buyer has a superior economic power over a supplier and each agent in a supply chain is unaware of each other. The supplier proposes pricing decision strategy to induce the buyer to choose the terms of contract for the benefit of the supplier. Then buyer decides the terms of contract to maximize her profit considering supplier's discount-policy. We also present a numerical example to illustrate the efficiency of pricing decision strategy.

This paper provides a real-time loading strategy for batch processing machines in which a number of jobs are simultaneously processed as a batch. The batch processing machines can be seen in both manufacturing industries (e.g., semiconductor, automobile and metal working) and service industries (transportation vehicles, mail shipment and theme park). This paper focuses on batch processing machines in semiconductor manufacturing. We present a look-ahead loading strategy for tardiness minimization where future arrivals and due dates are taken into consideration. Simulation tests are performed on the presented strategy and some existing loading heuristics under various production settings with different traffic intensities and forecasting errors. Experimental results show that our strategy provides the performance of good quality.

Recently, Social Commerce that provides customer with cheap deals is under the spotlight. The purpose of this study is to propose how to use social commerce on small restaurant business, which encompass almost a half of entire deals. We analyzed each element from the last transaction data of three social commerce company and survey obtained from the restaurant business. As a result, we can find that the purpose of promoting, the location of restaurant, whether is franchise or not, price and menu composition have an effect on sales of coupon. Based on these results, we proposed two step approaches to use the social commerce company. The first step is to decide whether social commerce is used or not and the second step is to define the detail content of deal including the social commerce company. We convinced that our proposed strategy is very helpful to the small restaurant which considers utilization of social commerce company.

Japan has established a strategic and concrete plan to respond in advance to the forthcoming Industrial Revolution era. The Fourth Industrial Revolution Strategy in Japan is divided into two types of strategies of utilizing strength and complementing weaknesses. The former belongs to 'real data utilization' and 'new robot development', and the latter belongs to 'global issues Solution'. In particular, the Japanese government is more aggressive than any other country in introducing the Japanese version of the Regulatory Sandbox system as a social verification system for the realization of the Society 5.0, which is regarded as the cornerstone of the Fourth Industrial Revolution. This study examines the key strategies presented in the main documents relating to the Fourth Industrial Revolution, and based on this consideration, we propose a suggestion worthy of reference when Korea develops the response strategy of the Fourth Industrial Revolution.

At the 8th National High-Performance Computing (HPC) Committee convened in 2021, the "National High-Performance Computing Innovation Strategy (draft) for the 4th Industrial Revolution Era" was deliberated and the original draft was approved. In this proposal, the Ministry of Science and ICT in KOREA announced three major plans and nine detailed projects with the vision of "Realizing the 4th industrial revolution quantum jumping by leaping into a high-performance computing powerhouse." Thereby the most important policy about national mid-term and long-term HPC development was established and called the HPC innovation strategy (hereinafter "the innovation strategy"). The three plans of the innovation strategy proposed by the government are: Strategic HPC infrastructure expansion; Secure source technologies; and Activate innovative HPC utilization. Each of the detailed projects has to be executed nationally and strategically. In this paper, we propose a strategy for the implementation of two items ("Strategic HPC infrastructure expansion" and "activate innovative HPC utilization") among these detailed plans.

Many economic development practitioners view cluster theory and analysis as constituting a general approach to strategy making in economic development, which may lead them to prioritize policy and planning interventions that cannot address the actual development challenges in their cities and regions. This paper discusses the distinction between strategy formation and strategic planning, where the latter is the programming of development strategies that are identified through a blend of experience, intuition, and analysis. Cluster theories and analytical tools can provide useful informational inputs into a strategy making effort and they can also be helpful for programming specific interventions (i.e., strategic planning). However, they should not be used as the exclusive or even predominant framework for filtering information about the competitive advantages of a region or for formulating strategy. To do so forces strategy making into a conceptual box defined by only one highly stylized theory of regional growth and development.

Since 2009, China has become biggest automobile supplier and consumer all over the world. Chinese government and automobile firms have been executed strategic and aggressive industry policy and business strategy for nurturing automobile industry as a core manufacturing industry. However, can we assure that all of these policy and strategy have positive effect on Chinese automobile industry? For fulfilling this gab, our research examined the government policy and firm's strategy in different development stage of Chinese automobile industry. According to research result, at initial stage(1983-1996), Chinese automobile industry has grown by technological learning and reverse engineering from Soviet Union, Japan and Germany. In rapid growing stage(1996-2009), Chinese automobile firms have succeed to develop and produce own brand product with 100% own technology. And this kind of quantum jump in technology development was conducted by joint venture policy and M&A strategy. However, at the fourth stage(2010-), Chinese government and firms have over invested and focused on Electric Vehicle manufacturing without developing core technology or SW. Overall, the old-fashioned policy and strategy module in manufacturing industry of China could have negative effect on its industry development.

The research is concerned with digitalization process and strategy of 'traditional industries'. Along with development of the Internet, new industries are emerging, while traditional industries are also rapidly shifting from old modes to new ones. Most traditional industries uy to enhance their adaptability for changing environment. The investigators argue the strategic intent of traditional industries can be categorized into the four different types. The typology consists of two axis. On the one hand, the directions of digitalization are rationalization and development of new business. On the other hand, the objects of digitalization are product and process. According to the typology, the research suggests neologism for the four strategies; product innovation strategy. new business strategy. rationalization strategy and process innovation strategy.
