Recently world industry trends is moved from manufacturing to service. As a result product-market ideology is central to the service enabler of the service. And value creation and delivery of consumer-oriented services as the core design industry is gaining popularity abroad. But the Service design to dispose of the whole process from planning to be done systematically is not yet established a clear concept. This study suggested problems of the current service design industry, service plans and strategies for the development of service design through open questionnaire and FGI(Focus Group Interview) for using service model methodology which is presented by HyeogIn Kwon et al.(2010). And we also consider 27 kinds of developing challenges for service design industry innovation by 6 sectors, such as workforce, R&D, legal framework, lay the foundation, knowledge service and collaborative service.

An approach to Just-In-Time for small job-shop-type manufacturers is presented. This is aimed at those who understand the pull production system, however, cannot afford either swift changeover in workcenters or frequent delivery to customers. First, as a production planning technique, a lot-sizing model entitled Multilevel Least Total Cost Model(MLTCM) is developed; The production order quantities of each components be those requiremensts of the end item production lot. The contribution of MLTCM is shown via simulation. Then, a framework of the Kanban operations is designed; A Production Control Kanban is introduced as a communication tool with Production Kanban in a job-shop.

Using a framework of the relational exchanges in relationship marketing, this study analyzed success factors of domestic CATV home shopping market which has rapidly grown recently. In order to carry out this analysis, the current status of domestic CATV home shopping market and the operational strategies of relationship marketing by the concerning enterprises were examined. More specifically, the exchange partners that have exchange relationship with domestic CATV home shopping companies were classified into the end-users, manufacturing companies, logistics and parcel delivery companies, SO companies, and other related industries, and then the operational strategies of relationship marketing for each partner were analyzed.

Unknowingly, the relationship between IT departments and their internal customers becomes that of client-supplier based on the mechanisms of marketing and competition. In addition, due to enhanced focus on the customer in the planning, development, and delivery of information service, IT service management(ITSM) has become increasingly important. These days IT management is focusing particularly on the 'de-facto' standard ITIL (IT Infrastructure Library) for implementing ITSM. It is linked as a part of CobiT’s 'deliver and support' domain, which is a framework of IT governance, and ISO/IEC 20000 is a unique international certification standards on the ITSM. This paper proposes the strategy and procedure for ITSM implementation based on ITIL with consideration of IT governance structure for manufacturing industries. It also presents a case study to share the lessons learned and results of an ITSM project.

This paper introduces the development of a range sensor based integrated navigation system for a multi-functional indoor service robot, called PSR (Public Service Robot System). The proposed navigation system includes hardware integration for sensors and actuators, the development of crucial navigation algorithms like mapping, localization, and path planning, and planning scheme such as error/fault handling. Major advantages of the proposed system are as follows: 1) A range sensor based generalized navigation system. 2) No need for the modification of environments. 3) Intelligent navigation-related components. 4) Framework supporting the selection of multiple behaviors and error/fault handling schemes. Experimental results are presented in order to show the feasibility of the proposed navigation system. The result of this research has been successfully applied to our three service robots in a variety of task domains including a delivery, a patrol, a guide, and a floor cleaning task.

In a competitive and globalized business environment, the need for the green products becomes stronger. To meet these trends, the environmental assessment besides delivery, cost and quality of products should be considered as an important factor in new product development phase. In this paper. a knowledge-based approximate life cycle assessment system (KALCAS) for the collaborative design environment is developed to assess the environmental impacts in context of product concept development. It aims at improving the environmental efficiency of the product using artificial neural networks consisting of high-level product attributes and LCA results. The overall framework of the collaborative environment including KALCAS is proposed. This architecture uses the CO environment to allow users on a wide variety of platforms to access the product data and other related information. It enables us to trade-off the evaluation results between the objectives of the product development including the approximate environmental assessment in the collaborative design environment.

This paper identifies defects to produce a reliable software and analyzes the relationship between defects. Also, this paper is intended to develop the relationship between defects and their causes to introduce. For the doing, first, to meet to customer satisfaction and make flexibility and productivity and second. to maximize market extension and financial outcome by controlling of quality and delivery.

High-Speed vehicles can be considered as multiple mobile nodes that move together in a large-scale mobile network. High-speed makes the time allowed for a mobile node to complete a handover procedure shorter and more frequently. Hence, several protocols are used to manage the mobility of mobile nodes such as Network Mobility (NEMO). However, there are still some problems such as high handover latency and packet loss. So efficient handover management is needed to meet Quality of Service (QoS) requirements for real-time applications. This paper utilizes the cross-layer seamless handover technique for network mobility presented in cellular networks. It extends this technique to propose QoS-aware NEMO protocol which considers QoS requirements for real-time applications. A novel analytical framework is developed to compare the performance of the proposed protocol with basic NEMO using cost functions for realistic city mobility model. The numerical results show that QoS-aware NEMO protocol improves the performance in terms of handover latency, packet delivery cost, location update cost, and total cost.

Military communications have limited resources such as poor bandwidth and insufficient link capacity. Numerous hosts in conventional IP networks, including the Tactical Information Communication Network (TICN), the tactical communication system of the Army, focus heavy traffic on a single server via end-to-end connections and in which data delivery latency is caused by exchanging routing information. Content-Centric Networking (CCN), one framework of Information-Centric Networking (ICN), is a novel Internet paradigm in which data can be accessed by the name of the content instead of the location information. This paper provides content caching strategies for applying CCN to military tactical IP networks based on TICN environment.
