본 연구는 사회복지분야에서는 그다지 시도되지 않았던 원가분석 방법과 특성을 검토하고, 장애인복지관 20개소를 대상으로 실제 장애인복지관서비스의 원가분석 결과를 사례로 제시하여 사회복지서비스 원가분석에 대한 함의를 제공하는 것을 목적으로 한다. 본 연구는 2002년 12월 기준 전국 장애인복지관 95개소 중 20개소를 최종적으로 분석하였다. 분석목적을 위해 해당 복지관의 2002년 세입 세출결산서와 연간사업실적보고서를 사용하였으며, 분석대상 복지관 실무자를 대상으로 중요도, 난이도, 업무비중에 근거하여 서비스별 가중치 조사를 실시하여 반영하였다. 원가분석방법으로는 '활동기준원가분석'(activity-based costing)이 아닌 '전통적 원가분석방법'(traditional cost accounting)을 사용하였다. 분석결과 2002년 기준 장애인복지관의 세출평균은 12억 6천 여 만원이며 이 가운데 65.8%는 인건비로, 13.2%는 재활사업비로 집행된 것으로 파악되었다. 서비스원가사례로 재가복지생활지원서비스의 경우 60분 기준 26,922원으로 직업상담직능평가의 경우 120분 기준 143,355원으로 계산되었다. 이러한 원가에는 낮은 임금수준 및 부동산비용 등이 반영되지 않아 실제 시장가격은 훨씬 높을 것으로 추정된다. 분석 결과는 추후 서비스의 중단, 축소, 확대, 자원배분 등 프로그램과 관련한 의사결정에 더 유용하게 활용될 수 있을 것이다.

NDF (No Defect Found) is a phenomenon in which defects have been found in the manufacturing, operation and use of a product or facility, but phenomenon of defects is not reproduced in the subsequent investigation system or the cause of the defects cannot be identified. Recently, with the development of the fourth industrial revolution, convergence of hardware and software technologies in various fields is spreading to products such as aircraft, home appliances, and mobile devices, and the number of parts is increasing due to functional convergence. The application of such convergence technologies and the increase in the number of parts are major factors that lead to an increase in NDF phenomena. NDF phenomena have a significant negative impact on cost, reliability, and reliability for both manufacturers, service providers and operators. On the other hand, due to the nature of NDF phenomena such as difficult and intermittent cause identification and ambiguity in judgment, it is common to underestimate the cost of NDF or fail to take appropriate countermeasures in corporate management. Therefore, in this paper, we propose a methodology for estimating NDF costs by the PAF model which is a quality cost analysis model and ABC (Activity Based Costing) technique. The methodology of this study suggests a detailed procedure and the concept to accurately estimate the NDF costs, using ABC analysis, accounting system information, and IT system data. In addition case studies have validated the methodology. We think this could be a valid methodology to refer to when estimating the cost of other parts. And, it is meaningful to provide important judgment information in the decision-making process based on quality management and ultimately reduce NDF costs by visualizing them separately by major variable factors.

IDEF0 is the IEEE standard for functional enterprise modeling and has been used for business process modeling or process mapping in US and Europe. But it does not reflect the potential benefits of modeling and simulation of the dynamic aspects of an enterprise or a system. On the other hand, simulation tools concentrate mostly on the simulation of material flows and are difficult to include information flows and control flows. Additionally, the simulation models that include elements such as queues, event generators and process nodes is a visual interactive representation for the model builder, but is inconvenient for the domain expert. In an attempt to fill that void, we provide an integration of business process and simulation models in this paper. An enhancement of the IDEF0, called parameterized IDEF0, is proposed and its conversion mechanism to network simulation model is developed. Using this methodology, business process models for alternative systems can be evaluated and compared through simulation on time, cost, and quality metrics. As an application of the proposed methodology, economic evaluation of EDI (Electronic Data Interchange) for time-based BPR (Business Process Redesign) is demonstrated. In addition to BPR, the developed methodology may be further integrated with ABC (Activity Based Costing), TQM (Total Quality Management), and economic evaluation of information systems.
