식품사고의 발생은 제품에 대한 소비자의 신뢰를 실추시키기 때문에 사회적으로 큰 문제가 아닐 수 없다. 식품의 유통구조가 복잡한 현대사회에서 소비자는 자신이 구매하려는 제품이 누가 언제 어떻게 생산했는지, 어떤 가공과정을 거쳤는지, 구입 제품이 어떻게 전달되는지 등 제품에 대한 정보를 확인하기 어렵고 식품안전 문제에 대처하기가 어려운 상황이다. 이는 제품의 공급자와 구매자(정보이용자)간에 정보의 비 대칭화에서 비롯된다고 할 수 있다. 따라서 식품안전문제를 해결하기 위해 정부에서는 관련법을 정비하고 시범사업을 추진하고 있으며 공급업체들은 제품에 대한 정보를 확인할 수 있는 보다 체계적인 시스템을 도입하는데 많은 관심을 보이고 있다. 본 연구에서는 정보 이용자들이 필요로 하는 정보를 제공할 수 있는 Traceability System을 이용하는 데에 유용한 자료를 도출하기 위한 목적으로 현재 Traceability System을 이용해본 경험이 있거나 이용하고 있는 정보이용자를 대상으로 Traceability System을 조직에 새로운 기술혁신의 관점으로 인식하고 Traceability System의 이용에 영향을 미치는 핵심 요인들을 실증분석하였다.

제품계열 공학(Product Line Engineering, PLE)은 핵심 자산을 이용하여 어플리케이션을 경제적으로 개발하는 대표적인 재사용 기술이다. PLE는 프레임웍(Framework) 공학과 어플리케이션 공학으로 구성된다. 프레임웍 공학은 한 도메인 내에 있는 여러 패밀리 멤버들이 가지고 있는 공통적인 기능인 핵심 자산을 개발하는 단계이고, 어플리케이션 공학은 핵심 자산을 패밀리 멤버에 맞게 인스턴스화하여 어플리케이션을 생산하는 단계이다. PLE는 핵심 자산을 이용하여 특정 어플리케이션을 개발함으로써 재사용성이 높을 뿐 아니라 어플리케이션을 적은 시간과 노력으로 만들 수 있으므로 개발하는 효율성도 높다. 그러나, PLE 개발 절차에 대한 산출물 정의 및 템플릿 제공이 미비하여 개발자들이 PLE 프로세스를 따라 산출물을 만드는데 어려움이 있고, 산출물간 관계 정의가 충분하지 못하여 산출물간 일관성을 유지하기 힘들어 개발자들은 PLE 프로세스의 실용적 적용에 어려움이 있다. 본 논문에서는 rLE의 핵심단계인 프레임웍 공학 과정의 각 단계마다 도출되는 산출물의 메타모델을 정의하고 각 산출물간의 추적 관계를 추적성 맵(Traceabitliy Map)으로 나타내며 산출물간 추적 관계를 적용할 수 있는 지침을 제시한다 마지막으로, 추적성 맵에 대한 평가와 적용되는 방법을 제시한다.

Current food-traceability platforms suffer from problems such as inconsistent traceability standards, a lack of public credibility, and slow access to data. In this work, a combined code and identification method was designed that can achieve more secure product traceability using the dual anti-counterfeiting technology of a QR code and a hidden code. When the QR code is blurry, the hidden code can still be used to effectively identify food information. Based on this combined code, a food-safety traceability platform was developed. The platform follows unified encoding standards and provides standardized interfaces. Based on this innovation, the platform not only can serve individual food-traceability systems development, but also connect existing traceability systems. These will help to solve the problems such as non-standard traceability content, inconsistent processes, and incompatible system software. The experimental results show that the combined code has higher accuracy. The food-safety traceability platform based on the combined code improves the safety of the traceability process and the integrity of the traceability information. The innovation of this paper is invoking the combined code united the QR code's rapidity and the hidden code's reliability, developing a platform that uses a unified coding standard and provides a standardized interface to resolve the differences between multi-food-traceability systems. Among similar systems, it is the only one that has been connected to the national QR code identification platform. The project has made profits and has significant economic and social benefits.

To realize the traceability of sustainable textile products, this study presents a low-carbon process through energy savings in the textile material manufacturing process. Traceability is becoming an important element of Life Cycle Assessment (LCA), which confirms the eco-friendliness of textile products as well as supply chain information. Textile products with complex manufacturing processes require traceability of each step of the process to calculate carbon emissions and power usage. Additionally, an understanding of the characteristics of the product planning-manufacturing-distribution process and an overall understanding of carbon emissions sources are required. Energy use in the textile material manufacturing stage produces the largest amount of carbon dioxide, and the amount of carbon emitted from processes such as dyeing, weaving and knitting can be calculated. Energy saving methods include efficiency improvement and energy recycling, and carbon dioxide emissions can be reduced through waste heat recovery, sensor-based smart systems, and replacement of old facilities. In the dyeing process, which uses a considerable amount of heat energy, LNG, steam can be saved by using "heat exchangers," "condensate management traps," and "tenter exhaust fan controllers." In weaving and knitting processes, which use a considerable amount of electrical energy, about 10- 20% of energy can be saved by using old compressors and motors.

This paper presents results from a computer-aided systems engineering application to system development projects. RDD-100 version of ALC Inc. was used in this work. The framework adopted in the study takes a unified approach to the system design and the process management associated with it, thereby coherent and full traceability between them is maintained. Conventional system engineering process supported by the tool is adopted in the system design. On the other hand, the same tool is also used to the systems engineering management to get full traceability between system design data and engineering management data. It is greatly helpful in managing many sub-contractors in the sense that the traceability can help identify the sub-project responsibility as well as the objectives of the project in coordination with interface requirements. We conclude with the advantage and limits of our unified approach.

Concerns about food safety continue to rise and under this situation, governments of some countries have reinforced their regulations more strictly for food safety. In order to prevent food safety incidents or, at least to minimize the impact, the preparedness is very important. As a consequence of this, traceability system has become an essential tool for food safety. Recently, it requires more prevention-based food safety control system. One of the most generally used systems for food safety control is Hazard Analysis and Critical Control Point (HACCP). Both traceability and HACCP systems can be integrated through Electronic Product Code (EPC) Sensor Network technologies which have four value propositions. In this paper, we will introduce the concept of product and process traceability system (P2TS) through the integration of three systems to improve food safety management. The final aim is to find out the added values of the P2TS.

It is well known that the test and evaluation plan (TEP) is very crucial in the successful development of safety-critical systems. As such, this paper discusses an approach to the development of the TEP for a system that should meet safety requirements in the systems development process. It is studied how to incorporate the result of preliminary hazard analysis (PHA) in generating the safety requirements. It is also discussed how to deal with them when the system requirements (i.e., functions, performance, constraints, components, etc) and the safety requirements are integrated into one model. While doing so, we have constructed the required traceability among them, which is necessary and very useful when the safety requirements need to be corrected or be changed. The use of the traceability makes it possible to easily check out whether and how the safety requirements are properly incorporated in the system design process. Furthermore, without the verified traceability, the system cannot be changed or upgraded later. In order to implement the model on a computer-aided tool, we have constructed a database (DB) schema. As a result, the implemented model/DB allows to automatically generate TEP which can be used to measure the performance and safety level of the developed system.

At present, DevOps environments are getting popular in software organizations due to better collaboration and software productivity over traditional software process models. Software artefacts in DevOps environments are vulnerable to frequent changes at any phase of the software development life cycle that create a continuous integration continuous delivery pipeline. Therefore, software artefact traceability management is challenging in DevOps environments due to the continual artefact changes; often it makes the artefacts to be inconsistent. The existing software traceability related research shows limitations such as being limited to few types of artefacts, lack of automation and inability to cope with continuous integrations. This paper attempts to overcome those challenges by providing traceability support for heterogeneous artefacts in DevOps environments using a prototype named SAT-Analyser. The novel contribution of this work is the proposed traceability process model consists of artefact change detection, change impact analysis, and change propagation. Moreover, this tool provides multi-user accessibility and is integrated with a prominent DevOps tool stack to enable collaborations. The case study analysis has shown high accuracy in SAT-Analyser generated results and have obtained positive feedback from industry DevOps practitioners for its efficacy.

It is well known that efficient management and thorough implementation of stakeholder requirements is vital for a successful development of a large-scale and complex system. Equally important is to make sure that all the requirements be correctly realized in the developed system. For the purpose, verification requirements are derived with traceability from the system requirements. This paper discusses a step by step process for constructing the requirements verification model which includes : 1) the schema modeling both requirements and their traceability; 2) the template documenting the verification requirements; 3) the verification model constructed from the schema; and 4) the test and evaluation plan that can be printed automatically.
