The product portfolio problem(PPP) is an optimization problem that determines the production quantity of a particular product to obtain the maximum profit among the n products. Linear programming(LP) is known as the only way to solve this optimization problem. The linear programming method is a problem that optimizes n linear functions and uses LINGO or Excel solver. This paper proposes a simple algorithm that uses CPR, a product cost-profit ratio, to sort in CPR descending order and then determines the maximum allowed production quantity by hand as the actual production quantity. As a result of applying the proposed algorithm to six experimental data, it was shown that more accurate results can be obtained compared to the linear programming method.

This study analyzes whether cooperating with various types of partners contributes to a company's innovation performance as well as the moderating effect of absorptive capacity and appropriability that may affect learning in such relationship. The hypothesis is that cooperating with diverse partners will have a positive effect on the innovation performance since it acquires their knowledge and information. In addition, an analysis is conducted on the moderating effect of absorptive capacity and appropriability on the relationship between alliance portfolio consisting various partners and innovation since absorptive capacity that encourages learning is likely to positively moderate the relationship between partner diversity and innovation while appropriability, the capacity to protect the proprietary technology, is likely to undermine learning from partners. The result of the empirical analysis on Korea's key industries, machinery and automobile, using the 2010 Korea Innovation Survey(KIS) data on manufacturing shows that cooperating with various types of technology partners has a positive effect on innovation performance and moderating effect on appropriability.

This research studied the determinants of private R&D investment by examining the innovation strategies of 481 small and medium enterprises (SMEs, their employee size is 5 or more and less than 300) in Busan, South Korea. The data is derived from the Technology Survey of Small and Medium Enterprises in 2001 and 2003. Three explanatory variables for the innovation strategies are the R&D portfolio, the organization (personnel) for R&D, and the strategic role of CEO for innovation. The technological levels of industries are controlled in the linear regression model. The dependent variable is the total private R&D investment of a firm in the given fiscal year. The empirical results indicate that the private R&D investment positively correlates with the complexity of the R&D portfolio, the formal organization for R&D team, and the increase of R&D personnel. The formal organization for R&D team and the number of R&D personnel are correlated with the increase of private R&D investment across the four groups in the manufacturing sector but not in the service sector. These findings suggest that the innovation policy needs to target firms who have complex R&D portfolios, the formal organization of R&D teams, and sufficient R&D personnel in order to increase the private R&D investment of SMEs in regions, with consideration of industrial characteristics.

In the past, executive managers made a decision based on personal experience and knowledge due to lack of the appropriate and timely information. With the development of information systems and technologies, efficiency and productivity of business operation has been enhanced. In this study, we propose a system design and architecture blue-print related to strategic decision making support system. The proposed system consists of 3 key parts; individual business feasibility test, business portfolio feasibility test, business portfolio management. The three key parts are comprised of 11 components to generate information and knowledge based on various data input from inside and outside of firm. This system is expected to provide objective and reliable output to users. In addition, the proposed strategic decision support system would help respond to a rapidly changing business environment.

특허의 가치는 몇 가지 환경 요인에 의해 달라진다. 시장의 진화가 특허의 가치를 저하시킬 수 있으며, 경쟁사간 특허의 분산 소유로 인해 특허의 가치가 저하될 수도 있다. 또한 자유로이 사용할 수 있거나 더 저렴한 대안 기술이 나타나 특허의 가치를 사라지게 할 수도 있으며, 특허 제도가 가진 결함이나 부실하게 작성된 특허 문서, 또한 사법 제도의 부실함으로 인해 특허의 가치가 작아질 수도 있다. 이러한 환경의 영향을 고려하여야만 환경의 변화에 대응하여 그 가치를 유지할 수 있는 특허(또는 특허 포트폴리오)를 식별하거나 창출할 수 있다.

본고에서는 급격한 IT융합연구 추진에 앞서 융합연구의 특성에 맞는 기획 관리체계에 대해 논해보고자 한다. 바람직한 융합연구를 위해서 기획체계에서는 창의적인 아이디어의 창출, 철저한 선행기획 연구, 적절한 융합기술의 포트폴리오 구성, 융합과제 전문가 및 Team 구성 등을 중점적으로 고려해야 하고, 융합연구 관리에서는 주도적이고 창조적 리더쉽을 가진 '융합PM'의 선정에 초점을 맞추어야 한다. 성공적인 융합연구를 위해서는 보다 자율과 창의를 살려주는 관리방식, 국내 외를 가리지 않고 최고의 전문가를 활용하는 평가방식으로의 전환이 필요하다.

Including the rolling black out in 2011, Korea has suffered from rapid increase of electricity consumption and demand forecasting failure for last five years. In addition, because of the Fukushima disaster, high fuel prices, and introduction of new generation sources such as renewables, the uncertainty on a power supply strategy increases. Consequently, a stable power supply becomes the new agenda and a revisino of strategy for new power generation sources is needed. In the light of this, we appraises the sixth basic plan for long term electricity demand and supply considering the changes of foreign and domestic conditions. We also simulate a strategy for the new power generation sources using a portfolio analysis method. As results, a diversity of power generation sources will increase and the share of renewable power generation will be surged on the assumptions of a cost reduction of renewable power sources and an increase of fuel costs. Particularly, on the range of a risk level(standard deviation) from 0.06 and 0.09, the efficient frontier has the most various power sources. Besides, the existing power plan is not efficient so that an improvement is needed. Lastly, the development of an electricity storage system and energy management system is necessary to make a stable and efficient power supply condition.

In fostering dynamic, innovative SMEs, hidden champion companies can be an appropriate model for SMEs to learn the success factors. On the other hand, the need for intellectual property management is becoming important as the value of a company is changing from a financial asset to an intellectual property. Therefore, in this study, the patent portfolio analysis of the hidden champion companies mentioned in Herman Simmon's book "Hidden Champion" was performed. As a result of the analysis, it was confirmed that patents are not possessed or patent activities are actively carried out and a differentiated intellectual property management strategy is implemented to improve patent quality depending on the characteristics of the technology possessed. The results of these studies can be used as basic data to prepare an intellectual property management strategy for companies that want to create opportunities to acquire monopoly rights and reduce patent maintenance and management costs. In addition, in this study, the patent IPC analysis verified that Herman Simmon's claim that "Hidden champions have the ability to focus on core competencies and focus on one technology" is valid.

The purpose of this study is to analyze the impact of individual savings banks' financial conditions on their loan portfolio after savings bank restructuring. The analysis results are as follows. First, it was estimated that the relationship between the rate of change in the NPL Ratio and the ratio of household loans has a significant positive value. Second, it was estimated that the interaction effect between the rate of change in the ratio of fixed and below loans and the spread of the deposit-to-deposit rate has a significant negative (-) value with the household loan weight. Third, the relationship between the asset size and the proportion of household loans was estimated to have a significant positive (+) value. In other words, it was analyzed that the financial situation of the savings bank affects the loan portfolio, and it should provide important implications for establishing policies for each financial situation of the savings bank. Depending on the financial situation in the future, there is a need to avoid excessive asset expansion of specific loans and preemptive soundness management.
