The product-level carbon footprint (PCF) is a comprehensive and widely accepted metric for sustainable product development. However, since a full PCF study in general is time and cost intensive, it is not feasible for the product development team to synchronize the activity to the main product development process. In addition, the current dedicated life cycle assessment (LCA) tools for calculating PCF, separated from the main product data management systems, have limitations to provide timely PCF information for design decision makings and collaborations between design and environment engineers. This paper examines the possibility of the extension of the current product data model that can support the PCF calculation with PDM (Product Data Management) databases. The product data model can represent not only the content of products but also context or system information of the products. The product data model can be implemented as a PDM database that can satisfy the needs for handy and timely PCF calculations from the consistent product data for dynamic design decision makings and engineering collaborations.

This paper introduces an approach to an ontology-based knowledge framework for product life cycle management (PLM). Participants in a product life cycle want to share comprehensive product knowledge without any ambiguity and heterogeneity. However, previous knowledge management approaches are limited in providing those aspects. Therefore, we suggest an ontology-based knowledge framework including knowledge maps, axioms and specific knowledge far domain. The bottom level, the axiom, specifies the semantics of concepts and relations of knowledge so that ambiguity of the semantics can be alleviated. The middle level is a product development knowledge map; it defines the concepts and the relations of the product domain common knowledge and guides engineers to process their engineering decisions. The middle level is then classified further into more detailed levels, such as generic product level, specific product level, product version level, and product item level for PLM. The top level is specialized knowledge fer a specific domain that gives the solution of a specific task or problem. It is classified into three knowledge types: expert knowledge, engineering function knowledge, and data-analysis-based knowledge. This proposed framework is based on ontology to accommodate a comprehensive range of unambiguous knowledge for PLM and is represented with first-order logic to maintain a uniform representation.

Optimal pricing research in general has been focused on profit maximizing strategy under the given product life-time T. Here we have tried to study the effect of uncertain product life-time on dynamic optimal pricing strategy. In reality, the life-time of product is more likely to be uncertain and not known as well. In terms of approximating the model to the concerned reality, so-called model validity, it seems to be more desirable to consider the uncertainty of product life-time into the optimal pricing strategy model, For this purpose, we tried two different approaches. One is to consider diverse product life-time probability functions under fixed life-time T. In this case, we might have the same product life-time as the previous study, but the process could be different in the expectation of product's discontinuity. The other is that life-time itself is not determined and thus it is the situation in which we can only decide optimal price on incremental basis. The former is the situation in which although we got some strong guess on life-time of a certain product, the pattern of expected life-time probability could be different. The question is what could be optimal pricing strategies on such different product life-time situations. But since in the latter, we don't assume any idea on the life-time of product. proper optimal pricing could be derived only from the past prices and diffusion information. While the latter seems to be safer in the aspect of model assumption, the former could be more realistic because we might have more or less a prior knowledge on the product life-time itself.

4차 산업혁명의 중요한 축이 되는 것이 스마트 팩토리이다. 스마트 팩토리는 사물인터넷과 지능형 감지시스템을 사용하여 생산의 효율성과 효과성을 최대한 유도하는 체제이다. 스마트 팩토리에서 소비자의 요구사항을 적극적으로 반영하고 소비자의 사후 관리까지의 전 과정을 관리할 수 있는 방법이 제품수명주기관리 기법이다. 제품수명주기 관리에 대한 연구는 많았으나, 4차 산업혁명 시대를 대비하여 제품수명주기관리 지식영역을 어떻게 구성해야 하는 지에 대한 연구는 부족했다. 본 연구는 제품수명주기관리의 측면에서 4차 산업혁명을 대비하는 전문가 그룹의 의견을 분석했다. 제품수명주기관리의 세부 지식영역에 대해서 향후 4차 산업혁명의 영향을 조사하였다. 제품수명주기관리의 변화되는 내용을 전문가 그룹을 대상으로 정성적 자료 분석(Qualitative Data Analysis) 기법을 이용하였다. 전문가의 의견을 기반으로 총 30개의 세부 지식영역으로 구성된 제품수명주기관리에 대해서 4차 산업혁명에 대비해 보완하거나 대비해야 하는 내용을 정리하였다. 본 연구의 시사점은 제품수명주기관리의 지식영역을 재정립하고 4차 산업혁명을 대비한 제품수명주기 관리 지식영역의 변화를 살펴보았다. 본 연구는 기존의 정의된 제품수명주기관리의 지식영역에 대하여 4차 산업혁명을 대비한 제품수명주기관리의 변화를 조사한 것이다. 향후 연구에서는 4차 산업혁명 시대에 맞는 제품수명주기관리의 지식영역을 다시 정의하고 전문가의 인식을 조사할 필요가 있다. 4차 산업혁명의 사회문화, 기술적인 변화 요인을 고려하여 제품수명주기관리의 영역, 범위를 새롭게 정의할 수 있을 것이다.

In recent, a general trend is observed towards more customized products and shorter product life cycles in manufacturing companies. In these companies, customers often wish to influence the product they order and to get a variant of product that meets their requirements. This environment is called as a customer-oriented manufacturing companies. This paper presents a procedure of product specification management for customer-oriented manufacturing companies by using product specification framework. This framework is founded on the product specification based product structure which is made of model, specification, function, and part. Also, a product specification management system(PSMS) is implemented by using the proposed product specification framework and is a core system in product data integration system. To illustrate an utilization of the proposed framework and procedure, a case of a ship engine product is applied. As a result, PSMS reduces delivery time and improves customer relationships. Moreover, the case shows that PSMS can be used as a tool for improving inter-department coordination within a company during product life cycle.

Recently, both the integration of product data during design and production and the effective management of information during full lifecycles have attracted attention from shipyards and ship owners as a result of recycling regulations and a desire for efficient operations. Generally, PLM (Product Lifecycle Management) supports a collaborative environment during the BOL (Beginning of Life) stage, while an ALM (Asset Lifecycle Management) system provides all of the information required to maintain, overhaul, and discard/recycle all or part of a vessel during the MOL (Middle of Life) and EOL (End of Life) stages. The main goal of this paper is to suggest the fundamental configuration of a PALM (Product Asset Lifecylce Management) system and a method that can be used to utilize a marine vessel's lifecycle information during the MOL, emphasizing the maintenance information during the middle of life. The authors also suggest a PALM system configuration in which lifecycle information can be collected by a PEID (Product Embedded Information Device) integrating a microcomputer, sensors, and wireless network communication. Through a prototype PALM system, the suggested features and PALM system configuration are implemented.
