Abstract: Today companies don’t have time and resources availability to stop their production to evaluate new layout and strategies, unless the results are guaranteed. Developing or redesigning products, gathering them in a product family and creating product platforms can be expensive tasks that represent a meaningful outlay for companies if they don’t have the adequate tools in order to facilitate the work. Thus, it is important to define the most appropriate manufacturing system as well as the performance of the chain value and the equipment layout in order to achieve an optimal production with the best quality and the shortest times and production costs. Therefore, computational tools, validated by working strategies and philosophies as Lean Manufacturing (LM) and Product Lifecycle Management (PLM) become necessary. After the evaluation of products, the value chain and the layout, these tools allow the construction of models and simulations as dynamic Value Stream Map (dynamic VSM), to analyze the actual process functioning or future process plans and PLM software, to estimate production flows, equipment and human labor requirements without stopping the normal production activities and providing competitive advantages to the company.

Abstract: The paper underlines the importance of the support systems for groups decisions in the decisional process of an organization, when a great number of decision-makers are working together to solve with maximum efficiency the problems appeared in different projects of the organization. A greater volume of information allows better statistical predictions, necessary in the adoption of decisions. We present a method that could solve different problems in many projects, based on the decision theory in risk and uncertainty conditions.

Abstract: The paper presents a conceptual model that pursues the understanding of the activities, the phases and the mechanisms of product design. The purpose of this model is to aid the product conception phase, as well as to develop software products that can furthermore aid design. The model takes into account the entire mental potential of the human being. The paper uses Jung's model in order to describe the various aspects of the human psyche. The paper presents a number of design models from the scientific literature. The proposed model defines domains of the needs imposed by stakeholders and specialists, functions domains and product domains. It explains the mechanism through which information is passed from one domain to another. As the information travels between domains, it undergoes a series of modelling and objectivation processes. The model is explained in better detail for the first phase of product design; however, it is applicable in all phases of product lifecycle. In the space and time coordinates used by the model, the conception appears as a spiral.

Abstract: With the background of the Aviation repair service industry, based on the analysis of the disadvantages of the past information technology solutions used in aviation repair management system, combined with the product lifecycle management concept, an aviation repair system structure based on the semantic service oriented architecture was built, which includes resource layer, basic structure layer, implementation layer and application layer. Finally, we discussed business process collaboration between enterprises.

Abstract: With the application of the ROHS standard in the products management, the Product Overall Lifecycle Management has been increasingly complex. Based on the UML2.0 modeling technology, this paper discussed the ROHS conformity system modeling process by the modeling tool VP-UML. According to the information model, the core data about Product Life Cycle can be converted to the XMI document, and be used to get the optimization of the model.

Abstract: High information content of integrated engineering activities stimulated development of product modeling during the past decades in order to support information management for lifecycle of products. Mechatronics is one of the engineering areas those require integrated product development techniques with strong knowledge based modeling and simulation in their background. The authors of this paper analyzed product modeling advancements in industrially applied product lifecycle management (PLM) systems in order to conceptualize new method to enhance knowledge content in product model. As a result of this analysis, they proposed a new method for control of product definition which extends the existing control in current PLM systems. This method is a contribution to solution for problems in current product modeling and is called as coordinated request based product modeling (CRPM). CRPM applies actual requested product definition (ARPD) as extension to currently applied product model. In this paper, the new method and entities as well as engineering objective definition and product behavior handling are explained as main contributions by the proposed modeling.

Abstract: This paper introduces a new method for the communication between human and product model entity definition processes. As product definition is moving into modeling in industrial product lifecycle management (PLM) systems, and built-in knowledge and intelligent computing content of product models increase, development of product modeling faces new challenges. More often, knowledge content is not in accordance with authorized human intent and different intents of different authorized humans for the same task are not in harmony. At the same time, authorized human needs help to understand decisions of other humans at application and modification of existing entity definitions in product model. The authors of this paper found the answer for the above challenges in a new human-model generation communication which extends the conventional product feature definition to higher level definition of objectives and allows for harmonizing different human intents. This communication applies higher level connection of human and product object generation process by knowledge based contextual chain in which model entities are more appropriate for knowledge content based decisions as the currently applied knowledge ware features. The proposed communication is devoted as extension to currently applied one so that the new decision assistance can be integrated with the well proven feature driven current industrial modeling.

Abstract: The information modeling of mold enterprises which based on Teamcenter product lifecycle management software platform is put forward, according to the analysis to the characteristics of injection mold manufacturing enterprises. User management model, product structure model and workflow management model have been established and implemented in the system management platform. It is not only enhance management level to data of mold enterprises, but also the scientific and effective methods of modeling and implementing can be provided for the other mold enterprises to carry out system platform of product lifecycle management.

Abstract: Product lifecycle management (PLM) is a kind of solution, software technology and a business strategy, which play an indispensable role in the enterprise informatization and network management. In this paper, Teamcenter management software of SIEMENS is applied as basic platform of implementing PLM project, the fundamental network structure and main functions and solutions are introduced, furthermore, it also mainly researches the implementation strategies and process of PLM project and analyses the application values and advantages of PLM project for the enterprises.

Abstract: The paper analyses problems existing in integration models of product design and manufacturing in enterprises. Under the theory of product life cycle management (PLM) and via the platform of J2EE, it builds a framework for establishment of integration architecture in product design and manufacturing based on knowledge engineering. The paper gives a detailed introduction to the structure, function characteristics and realization forms of the architecture. On the basis of this, the paper then studies integration methods of the information system based on XML and explores key technologies in the knowledge base plus network safety of the architecture. Finally, the paper emphatically analyzes types of flow of traditional knowledge and digital knowledge in enterprise knowledge management. The proposed architecture has realized close integration of various sectors so that knowledge runs through the whole process of product life cycle. As a result, the architecture can satisfy modern enterprises’ demand for collaborative manufacturing, resource sharing and network integration while supporting knowledge management and technological innovation.
