    학위논문 (박사)-- 서울대학교 대학원 : 공과대학 산업공학과, 2018. 2. Park, Jinwoo.Supply chain performance measurement has become one of the most important and critical management strategies in the pursuit of perfection and in strengthening the competitive edges of supply chains to face the challenges in todays global markets. To constantly cope with the resulting rapid changes and adopt new process designs while reviving supply chain initiatives and keeping them alive, an effective real-time performance-based IT system should be developed. And there are many researches on supply chain performance measurement system based on the real-time information system. This thesis proposes a standard framework of a digitalized smart real-time performance-based system. The framework represents a new type of smart real-time monitoring and controlling performance-based IT mechanism for the next-generation of supply chain management practices with dynamic and intelligent aspects concerning strategic performance targets. The idea of this mechanism has been derived from the main concepts of traditional supply chain workflow and performance measurement systemswhere the time-based flow is greatly emphasized and considered as the most critical success factor. The proposed mechanism is called Dynamic Supply Chain Performance Mapping (DSCPM), a computerized event-driven performance-based IT system that runs in real-time according to supply chain management principles that cover all supply chain aspects through a diversity of powerful practices to effectively capture violations, and enable timely decision-making to reduce wastes and maximize value. The DSCPM is proposed to contain different types of engines of which the most important one is the Performance Practices and Applications Engine (PPAE) due to its involvement with several modules to guarantee the comprehensiveness of the real-time monitoring system. Each of these modules is specified to control a specific supply chain application that is equipped with suitable real-time monitoring and controlling rules called Real-Time Performance Control Rules (RT-PCRs), which are expressed using Complex Event Processing (CEP) method. The RT-PCRs enable DSCPM to detect any interruptions or violation smartly and accordingly trigger real-time decision-making warnings or re-(actions) to control the performance and achieve a smart real-time working environment. The contributions of this dissertation are as follows: (1) building a conceptual framework to digitalize the supply chain, based on their strategic performance targets, deploying IoT technologies to convert its resources to smart-objects and therefore enable a dynamic and real-time supply chain performance measurement and management. (2) Demonstrating the feasibility of the DSCPM concerning performance targets by developing some practices and tool modules that are supplied with RT-PCRs (e.g., Real-time Demand Lead-time Analysis, Real-time Smart Decision-making Analysis (RT-SDA), Real-time Supply Chain Cost Tracking System (RT-SCCT), etc.). (3) Verifying the effectiveness of RT-PCRs in RT-SDA and RT-SCCT modules by building simulation models using AnyLogic simulation software.Chapter 1.

    The present day is marked by the economic expansiveness of societies and the adoption and adaptation of intelligent technologies. In this hyper-world, customers expect a personalized offer enhanced with customized service, which results in the introduction of sustainable and intelligent solutions—among other services. What becomes important is not so much the "Primum non nocere" of creation as much as the "go smart to the future" in creating. The smart logistics concept is a representation of this trend. The subject of the article is an analysis of the impact of the application of the smart idea in the field of sustainable development on changes in logistics in customer service at the last-mile stage. The source of this article is exploratory research of secondary sources, including books, articles, and reports, which has been subjected to a critical content analysis. The obtained results made it possible to design and implement an explanatory study of online-buying habits of people based on the CAWI (Computer Assisted Web Interview) methodology. The collected material has become the basis for the authors to indicate the applicability of smart logistics in the field of last-mile logistics, which can be used by researchers and training institutions in the field of professionalization of management of intelligent logistics processes in customer service at the last-mile stage. The last-mile service in logistics involves reaching the largest possible number of recipients, however, it has a negative impact on the natural environment, which, of course, contradicts the concept of sustainable development, including trends that are noticeable in the logistics market, customers, and in the law. Hence, it is important to look for solutions that allow us to achieve the appropriate level of customer service in the last mile, but at the same time, take care of the natural environment. The study was narrowed down to the Polish perspective due to the growing demand for last-mile logistics services. Moreover, Poland is still a country where the concept of sustainable development is not fully understood and used. The research allowed us to indicate the directions of development of the last-mile service processes by considering the technological innovations that may support the application of the concept of sustainable development

    We have entered the big data era. Organizations are capturing, storing, and analyzing data that has high volume, velocity, and variety and comes from a variety of new sources, including social media, machines, log files, video, text, image, RFID, and GPS. These sources have strained the capabilities of traditional relational database management systems and spawned a host of new technologies, approaches, and platforms. The potential value of big data analytics is great and is clearly established by a growing number of studies. The keys to success with big data analytics include a clear business need, strong committed sponsorship, alignment between the business and IT strategies, a fact-based decision-making culture, a strong data infrastructure, the right analytical tools, and people skilled in the use of analytics. Because of the paradigm shift in the kinds of data being analyzed and how this data is used, big data can be considered to be a new, fourth generation of decision support data management. Though the business value from big data is great, especially for online companies like Google and Facebook, how it is being used is raising significant privacy concerns

    A Dissertation Submitted in Partial Fulfillment of the Requirements for the Award of the Degree of Master of Science in Embedded and Mobile Systems of the Nelson Mandela African Institutions of Science and TechnologyIn the supply chain and logistics industry, the precision of the data assets inventory plays a crucial role in warehouse activities. The operations like storage locations arrangement, inventory management, and maintaining the flow of incoming and outcoming goods lead to the success of the warehouse. Nowadays, most people prefer online shopping all over the world because it is faster than local trade. Thus, there's massive information in the supply chain and logistics sector to explore in order to improve operations of the warehouse such as receiving, ordering, shipping, storage assignment to facilitate the automation in the warehouse. As result, this research is proposed to improve warehouse activities. The RFID-based warehouse management system automates storage and inventory management without any human intervention. In order to accomplish the objectives of the study, a software program was developed with sets of rules, and an algorithm to optimize the inventory operations with the help of RFID technology. The predefined rules help in giving priorities to some of the selected products to store and retrieve in the indicated location. The long-range RFID reader is used in this project. The reader is attached to the entrance of the gate of the warehouse to facilitate the reading of incoming goods. Once the goods arrive in the warehouse, the storage location function will assign to each one the storage location and update status in the database. A handheld reader attached to the forklift facilitates inventory management and communicates with the application via a wireless network and finally store data in the database for future use. After developing this system, a test was conducted for testing the feasibility and applicability of the system. The output showed that the inventory management operation was made strides, and the correctness of inventory location increased from 72.8% to 99%. The cycle time moreover decreases from 60 minutes to 20 minutes which is down to 28.79%

    New technologies have a great influence on the production process in modern factories. Introducing new techniques and methods is crucial to optimize and enhance the working of factories. However, ensuring a reliable and correct integration requires complete evaluation and assessment. In this thesis I utilize RFID systems and image processing to develop and implement real time solutions to enhance and optimize the production and assembly processes. Solutions include: RFID based CEP to detect production error, image processing based errors detection to detect post-assembly errors, and RFID based HCI to help workers in assembling products. Errors that are detected using RFID are: sequence errors, synchronization errors, pre-assembly order errors, part-product mismatch error, and missing parts errors. Errors that are detected using image processing are: incorrect part position errors and missing parts errors. RFID based HCI consists of a tool to help workers at assembly points to correctly assemble parts to their products using visual instruction. I have constructed prototypes for all the solutions. As well, I have deployed them in the Lernfabrik(learning factory) which is a real manufacturing environment for practising the production and assembly processes for trainees and students. Under the optimal settings of the RFID readers and tags, the system detects all types of errors reliably in real time. The image processing algorithm detects errors with 100% accuracy in real and normal lighting conditions of the Lernfabrik

    The Engineering Doctorate (EngD) was conducted in conjunction with BT Research on state-of-the-art Wireless Sensor Network (WSN) projects. The first area of work is a literature review of WSN project applications, some of which the author worked on as a BT Researcher based at the world renowned Adastral Park Research Labs in Suffolk (2004-09). WSN applications are examined within the context of Machine-to-Machine (M2M); Information Networking (IN); Internet/Web of Things (IoT/WoT); smart home and smart devices; BT’s 21st Century Network (21CN); Cloud Computing; and future trends. In addition, this thesis provides an insight into the capabilities of similar external WSN project applications. Under BT’s Sensor Virtualization project, the second area of work focuses on building a Generic Architecture for WSNs with reusable infrastructure and ‘infostructure’ by identifying and trialling suitable components, in order to realise actual business benefits for BT. The third area of work focuses on the Open Geospatial Consortium (OGC) standards and their Sensor Web Enablement (SWE) initiative. The SWE framework was investigated to ascertain its potential as a component of the Generic Architecture. BT’s SAPHE project served as a use case. BT Research’s experiences of taking this traditional (vertical) stove-piped application and creating SWE compliant services are described. The author’s findings were originally presented in a series of publications and have been incorporated into this thesis along with supplementary WSN material from BT Research projects. SWE 2.0 specifications are outlined to highlight key improvements, since work began at BT with SWE 1.0. The fourth area of work focuses on Complex Event Processing (CEP) which was evaluated to ascertain its potential for aggregating and correlating the shared project sensor data (‘infostructure’) harvested and for enabling data fusion for WSNs in diverse domains. Finally, the conclusions and suggestions for further work are provided

    This thesis contains the research on the key change adoptive agents/forces and the solu-tions to the world‟s rapidly growing and one of the most consumer facing industry. The trillions worth retail industries are undergoing the period of important restructuring inter-nally and externally. The author highlights the key factors that force the retail industry to adopt modern technologies for their daily business processes in order to be more competi-tive. The factors have been viewed in two perspectives 1-Internal (store/warehouse man-agement, human capital) and 2-Externally (customers, suppliers). In response of these factors, the research presents state of the art 1-Self Checkout System 2-RFID 3-Cloud Computing as tested and proven technologies that has been observed and implemented in the “Future Stores” by big box retailers. Finally the author discusses the tangible and in-tangible benefits to the retail business derived from the implementation of mentioned technologies. To meet the research demands, the writer constructs a theoretical frame-work by using the descriptive and exploratory research method as a secondary resource; while empirical research was conducted through semi structured phone interviews with experts from the retail industry and the retail management consultants. The results derived from theoretical study and empirical research show that the use of updated retail management technologies like Self-checkout System, RFID and Cloud Computing can reduce cost and management pain fairly. While the bigger impact of such adoptions is to build a seamless supply chain, customer experience management and business intelligence system; which plays a vital role to prolong the competitiveness and life cycle of retail business against future economic setbacks
