Korean Naval Ship acquisition processes are very complicate. There are 4 phases, Feasibility Study, Concept Design, Basic Design, Detail Design and Construction. A number of organizations and support groups exist to acquire naval war ships. Thus, It is very important how to establish traceability about requirements. This work has investigated how to improve traceability about requirements using Shipboard Work Breakdown Structure.

In this paper, the traceability system for rice which is based on RFID technology is introduced. The traceability system plays an important role in the quality management for rice and rice-related food since this system can provide the information of all food chain (production, treatment, distribution and sales etc.) and more quickly identify the cause of the rice and rice-related accident. The main result of the this paper is the basic structure for the traceability system based on RFID technology. To show the implementation case based on this basic structure, the effectiveness of the traceability system is verified. In addition, the prerequisites condition for effective implementation is proposed.

Recently, a railroad system has a big and complicated structure of specification. Therefore, traceability between specification need to be identified for design change management and this is many engineer's concerns. Traceability means technical relationship. This is to trace other specification or component connect with relevant problem in case some problem should be examined. Traceability between functional specification can be proved through functional analysis essentially. This study will introduce an application method of functional analysis in the case of practical use project of MAGLEV train. And we propose the guide to identify traceability between function through functional analysis.

In December 2014, Livestock and Livestock Products Traceability Act was established, allowing consumers to receive livestock traceability information. While the Livestock Traceability System provides consumers with transparent and fair information about their food, it has brought increased workload and penalty burdens to stakeholders in the livestock industry. In this paper, we propose an IoT system for inventory management based on traceability numbers to enable sellers to conveniently provide livestock traceability information to consumers. We analyzed the protocol for managing data from electronic scales and conducted functional testing and verification on mobile devices. Furthermore, we implemented the design and system functionality, taking into account UI/UX on Android OS-based devices to synchronize and interconnect traceability and product information with electronic scales. We anticipate that the proposed approach will minimize user inconvenience and raise production efficiency in the existing market.

Block Chain is a technology that records and shares distributed ledgers without a central authority, providing a decentralized platform for transparent transactions in the business and enhancing transparency and traceability in all transactions to ensure trust in the transaction. Despite initial doubts about this technology, it is committed to adopting, adapting and improving the technology in a wide range of industries, including finance, government, security, logistics, food, medical, legal, and real estate. This study examines this technology, its applicability and potential benefits to the manufacturing supply chain. A tracking system of manufacturing supply chain to visualize transparency and traceability is implemented, and the conditions for adopting the technology in the manufacturing supply chain and the issues to be addressed are discussed.

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.

The management of user requirements for information system development is a key element. The traceability has been studied in a specific method as using a traceability table or SOA related to the requirement management. But there are few case about proposing a objective and quantified evaluation method and judgement criterion for none-technical business managers. This researcher has proposed, easy to access by unprofessional and objective and qualifiable, evaluation methods and criteria of Judging for adequacy of requirements reflection in the development process of information system for the government office through a previous case study. In this study, I will give consideration to study the limitations of previous studies and improve the evaluation formula for measuring the reflection of the requirements and derive, reviewed to provide a variety of criteria for each business, through business case analysis.

Implementing the automatic identification in supply chain management is essential for effective and efficient process control. Though the GTIN based bar code system is generally used as an automatic identification method in most industries, it can not identify individual item, and is not appropriated for products' reliability and safety management. So the RFID system with EPC is considered as a better solution for resolving those problems. This study reviewed automatic identification code systems and the attributes and characteristics of RFID Gen 2 which became a global standard recently for supply chain management. Particularly, this study analyzed RFID Gen 2 systems' read rates on various conditions including distances between tags and readers and between antennas, condensation, and several packing materials in practical supply chain environment. The results of this study showed that the RFID Gen 2 had high read ratio in practical application and would be adopted as a new automatic identification means for traceability systems.

Ubiquitous computing which is called, the innovation of the 21st Century is a core technology of next generation. RFID technology is noticed, and physical distribution, home network, telematics, like industry automatization are developed by using various technique. Particulary, They use RFID technology for fashion and beauty industry, So, supplying network management, physical distribution management and warehouse management are investigated for the automatization. What we have investigated so far, a traceability system is made of ubiquitous sensor network for monitoring fashion and beauty industry environment. The proposed system using EPC network can provide information of industrial products traceability quickly and efficiently. Moreover, this system with RFID Technology gives intelligence of distribution and record. In this paper, We recommend the vision of Ubiquitous convergence of fashion and beauty industry.
