본 연구는 의료기관과 호텔산업에서의 아웃소싱 성과에 영향을 미치는 선행요인을 비하여 서비스기관에 따른 차이가 존재하는지를 밝히고자 하였다. 이를 위해 의료기관과 호텔을 중심으로 실제 아웃소싱 업무를 담당하고 있는 관리자를 대상으로 약 2개월 간 조사를 실시하였다. 총 350부를 배포하여 325부를 회수하였으나 이 중 불성실한 응답으로 분석대상으로 적합하지 않는 자료 6부를 제외한 319부를 최종분석에 사용하였다. 이 중 의료기관은 155부이었으며, 호텔은 164부를 최종분석에 사용하였다. 첫째, 아웃소싱 위탁업체와 수행업체 담당자간의 비공식적 인간관계는 의료기관과 호텔산업 모두 신뢰에는 유의한 영향을 미치지 않는 것으로 나타났으나 아웃소싱 수행정도에는 의료기관만이 영향을 미치는 것으로 나타나 차이를 보였다. 특히 의료기관의 경우 아웃소싱 수행업체와의 관계형성이 인턴부터 전문의가 될 때까지 오랜 기간동안 꾸준하게 형성된 비공식적 인간관계 특성에 따른 결과로 이해된다. 둘째, 의료기관 및 호텔산업 모두 의사소통이 신뢰에 유의한 영향을 미치는 것으로 나타나 아웃소싱의 특성상 상호간 원활한 의사소통이 긍정적인 관계형성이 이루어질 수 있다는 것을 강조하고 있다. 셋째, 아웃소싱 수행업체의 기회주의적 행동이 신뢰 및 아웃소싱 수행정도에 두 기관 모두 부(-)의 유의한 영향을 나타내 수행업체의 기회주의적 행동은 상호간 우호적인 관계형성보다는 불편한 감정이나 갈등을 유발할 가능성이 크다는 것을 나타냈다. 넷째, 서비스 인프라가 신뢰에 미치는 영향은 의료기관의 경우 유의한 영향을 미치지 않은 것으로 나타났으나 호텔산업은 유의한 영향을 미치는 것으로 나타나 차이를 보였다. 또한 서비스인프라가 아웃소싱 수행정도에는 두 기관 모두 유의한 영향을 미치는 것으로 나타났다. 다섯째, 아웃소싱 위탁업체인 의료기관 및 호텔과 수행업체간 신뢰는 아웃소싱 수행정도에 두 기관 모두 유의한 영향을 미치지 않는 것으로 나타났다. 반면에 신뢰는 아웃소싱 성과에 두 서비스기관 모두 유의한 영향을 미치는 것으로 나타나 의료기관 및 호텔에서 아웃소싱을 수행함에 있어 계약적 측면의 업무수행보다는 아웃소싱업체와의 상호 파트너십을 통해 관계적 측면을 강화하는 것이 상호간 신뢰뿐만 아니라 업무에 대한 성과도 높게 이끌 수 있음을 나타냈다. 마지막으로 아웃소싱 위탁업체의 아웃소싱 수행정도가 아웃소싱 성과에 두 기관 모두 유의한 영향을 미치는 것으로 나타나 아웃소싱의 수행이 활발할수록 이에 따른 성과도 증대됨을 나타내고 있다.

The purpose of this research is to evaluate the feasibility of outsourcing test/inspection activity in construction work. This research conducted a questionnaire of interested parties as well as a survey by Analytic Hierarchy Process (AHP) with experts on quality control. For the evaluation by AHP, five criteria were adopted and a number of pair-wise comparisons were conducted through two stages. Finally, the weighting coefficient to approve the outsourcing was calculated at 0.606 and it therefore appeared more reasonable to permit rather than prohibit outsourcing. According to the AHP result, it was found that outsourcing would be necessary to enhance the objectivity and specialties of quality testing and inspection, even though somewhat undesirable in terms of enhancing a sense of responsibility and systemically conducting the testing and inspection.

An integrated process planning and scheduling model considering outsourcing in manufacturing supply chain is proposed in this paper. The process planning and scheduling considering outsourcing are actually interrelated and should be solved simultaneously. The proposed model considers the alternative process plans for job types, precedence constraints of job operations, due date of production, transportation time and production information for outsourcing. The integrated states include:(1) Operations sequencing, (2) Machine selection, (3) Scheduling with outsourcing under the due date. To solve the model, a heuristic approach based on genetic algorithm(GA) is developed. The proposed approach minimizes the makespan considering outsourcing and shows the best operation-sequences and schedule of all jobs.

The objective of this research is to identify the process of knowledge transfer and to examine the effect of IT human capability on knowledge transfer in information systems outsourcing. Through a field survey, it is found that clients' IT human capability significantly affects on cooperative learning with vendors and knowledge transfer from vendors to clients. The survey also shows that clients' trust with vendors indirectly enhances the knowledge transfer by increasing the cooperative learning. This study provides a solution of knowledge transfer problem in information systems outsourcing. Also it brings out issues that can be accrued in the outsourcing situation, such as clients' dependency on vendors and knowledge asymmetries developed in favor of the vendors. These issues should be topics for future research on information systems outsourcing.

With the development of cloud computing and widespread availability of mobile devices, outsourcing computation has gotten more and more attention in cloud computing services. The computation of bilinear pairing is the most expensive operation in pair-based cryptographic schemes. Currently, most of the algorithms for outsourcing bilinear pairing have small checkability or the outsourcers need to operate expensive computations. In this paper, we propose an efficient algorithm for outsourcing bilinear pairing with two servers, where the outsourcers can detect the errors with a probability of 1 if the cloud servers are dishonest, and the outsourcers are not involved in any complex computations. Finally, the performance evaluation demonstrates that the proposed algorithm is most efficient in all of fully verifiable outsourcing algorithms for bilinear pairing.

The demand for facility used in producing multi-products is changed dynamically for discrete and finite time periods. The excess or the shortage for facility is occurred according to difference of the facility capacity size and demand for facility through given time periods. The shortage facility is met through the outsourcing production. The excess facility cost is considered for the periods that the facility capacity is greater than the demand for the facility, and the outsourcing production cost is considered for the periods that the demand for facility is greater than the facility capacity. This paper addresses to determine the facility capacity size, outsourcing production products and amount that minimizes the sum of the facility capacity cost, the excess facility cost and the outsourcing production cost. The characteristics of the optimal solution are analyzed, and an algorithm applying them is developed. A numerical example is shown to explain the problem.

Information systems(IS) outsourcing has become a very important management strategy of implementing IS and many studies on the IS outsourcing approach had been performed in the organizations. But it isn't still show how to out source the IS functions and how to offer quantitative magnitude for judgement. To offer a quantitative decision model that can help practitioners set priority and reap the most benefits from outsourcing, we show outsourcing structure including 3 factors (strategic, economic and technological benefit) and sub-levels which is different from the Yang and Huang's model. Also, we compute the weight of alternatives using analytic hierarchy process to find a priority of the IS outsourcing. As a result of analysis, we suggest systematic steps and quantitative model to increase the precision of decision making. 1)

Computer attacks on vulnerable software are ubiquitous. Today's attacks on client PCs can be used to create armies of zombie computers that are capable of wide reach attacks on high profile businesses and governments. The simple act of patching software vulnerabilities will certainly mitigate this problem, but patching has its own set of problems. Further, it is frequently the case that patches which are available to mitigate vulnerabilities are not being made on a timely basis and sometimes are not being made at all. One solution to the patch management dilemma is outsourcing. This paper notes that outsourcing is not a carte blanche decision that can be made based on dollars, but rather that a contingency decision matrix can provide guidance on outsourcing solutions for patch management and other security components as well. The matrix recognizes that IS staff expertise and employee security awareness are two important factors in the outsourcing decision.

In this study, outsourcing behaviors of shoe manufacturing companies were studied and four types of outsourcing were generated based on qualitative data collected through in-depth interviews with 21 practitioners of shoe manufacturing companies. In results, shoe manufacturers are actively adopting outsourcings in production of raw materials(RM) as well as final products(FP). However, relatively less effect is being made on outsourcing in the field of product planning, international marketing and information technology. Four types of outsourcing include shoe manufacturers focusing on: 1) domestic production of RH and FP, 2) domestic production of RM and international production of FP, 3) domestic/international production of RM and FP, and 4) international production of RH and FP. These types were differed. from their manufacturing items, product planning skills and target markets of shoe manufacturing companies.
