서비스 관점에서 국제표준기구가 요구하는 수준의 인증 서비스를 SW 개발과정에 도입하는 것은 매우 중요하다. 그 이유는 우리 산업에서 ICT가 차지하는 비중이 매우 높을 뿐만 아니라, ICT 관련 SW에 대한 국제적인 수준의 인증은 필수적이기 때문이다. 그리고 이를 위해서 ADONIS와 같은 과학적이며 체계적인 도구를 기반으로 한 인증 서비스가 절대적으로 요구된다. 본 논문에서는 이러한 시대적, 사회적 요구에 부응할 수 있는 하나의 새로운 방법 체계를 제시하였다. 이 체계는 우리 산업에 국제적인 수준에서 요구되는 SW의 안전성에 대한 인증 서비스를 제공하였고, 이러한 서비스는 다른 영역에도 적용될 수 있다. 이러한 체계를 설명하기 위해 EU우주항공국의 표준안 중 ECSS-E-40의 인증을 위한 서비스의 설계와 이에 대한 보증이 어떻게 이루어지는지 서비스 공학 측면에서 살펴보고, ADONIS를 통해서 보여주고자 한다. 본 논문은 E-40 표준안의 항목 중 SW의 명세와 검증에 관해 집중하며, 검증의 대상은 안전성(Safety)을 우선으로 한다.

The capabilities ofBusiness Process Management Systems (BPMS's) are continuously extended to increase theeffectiveness of the management and enactment of business processes. This paper identifies the challenge ofcase prediction, which for a specific case under the control of a BPMS deals with the estimation of the remaining time until it is completed. An accurate case prediction facility is a valuable tool for the operationalcontrol of business processes, as it enables the pre-active monitoring of time violations. Little research has beencarried out in this area and few commercial tools support case prediction. This paper lists the requirements onsuch a facility and sketches sonae directions to reach a solution. To illustrate the depth of the problem, a smallaspect of the problem is treated in more detail. It involves the complex relations between tasks and resources inbusiness processes, which makes an exact analytical approach mfeasible.

With the increased awareness of energy consumption as well as the environmental impact of building operations, architects, designers and planners are required to place more consideration on sustainability and energy performance of the building. To ensure most of those considerations are reflected in the building performance, critical design decisions should be made by key stakeholders early during the design development stage. The application of BIM during building energy simulations has profoundly improved the energy analysis process and thus this approach has gained momentum. However, despite rapid advances in BIM-based processes, the question still remains how ordinary building stakeholders can perform energy performance analysis, which has previously been conducted predominantly by professionals, to maximize energy efficient building performance. To address this issue, we identified two leading building performance analysis software programs, Energy Plus and IES (IES ), and compared their effectiveness and suitability as BIM-based energy simulation tools. To facilitate this study, we examined a case study on Building Performance Model (BPM) of a single story building with one door, multiple windows on each wall, a slab and a roof. We focused particularly on building energy performance by differing building orientation and window sizes and compared how effectively these two software programs analyzed the performance. We also looked at typical decision-making processes implementing building energy simulation program during the early design stages in the U.S. Finally, conclusions were drawn as to how to conduct BIM-based building energy performance evaluations more efficiently. Suggestions for further avenues of research are also made.
