A Knowledge-reuse Based Intelligent Reasoning Model for Worsted Process Optimization

The textile process planning is a knowledge reuse process in nature, which depends on the expert’s knowledge and experience. It seems to be very difficult to build up an integral mathematical model to optimize hundreds of the processing parameters. In fact, the existing process cases which were recorded to ensure the ability to trace production steps can also be used to optimize the process itself. This paper presents a novel knowledge-reuse based hybrid intelligent reasoning model (HIRM) for worsted process optimization. The model architecture and reasoning mechanism are respectively described. An applied case with HIRM is given to demonstrate that the best process decision can be made, and important processing parameters such as for raw material optimized.

Interactive Training Model of TRIZ for Mechanical Engineers in China

Abstract： Innovation is a process of taking an original idea and converting it into a business value, in which the engineers face some inventive problems which can be solved hardly by experience. TRIZ, as a new theory for companies in China, provides both conceptual and procedural knowledge for finding and solving inventive problems. Because the government plays a leading role in the diffusion of TRIZ, too many companies from different industries are waiting to be trained, but the quantity of the trainers mastering TRIZ is incompatible with that requirement. In this context, to improve the training effect, an interactive training model of TRIZ for the mechanical engineers in China is developed and the implementation in the form of training classes is carried out. The training process is divided into 6 phases as follows： selecting engineers, training stage-l, finding problems, training stage-2, finding solutions and summing up. The government, TRIZ institutions and companies to join the programs interact during the process. The government initiates and monitors a project in form of a training class of TRIZ and selects companies to join the programs. Each selected companies choose a few engineers to join the class and supervises the training result. The TRIZ institutions design the training courses and carry out training curriculum. With the beginning of the class, an effective communication channel is established by means of interview, discussion face to face, E-mail, QQ and so on. After two years training practices, the results show that innovative abilities of the engineers to join and pass the final examinations increased distinctly, and most of companies joined the training class have taken congnizance of the power of TRIZ for product innovation. This research proposes an interactive training model of TRIZ for mechanical engineers in China to expedite the knowledge diffusion of TRIZ.

Product Model Evolvement and Configuration Knowledge Reuse Method

Configuration knowledge is a dynamic information set which is evolving and enriching on and on. Product model is the instantiation of configuration knowledge and the evolution of configuration knowledge is the essential inherent reason which causes the models dynamic evolvement. In the traditional model evolvement process, the inheriting and reuse of configuration knowledge was always ignored. Aim at solving the above problem, the multistage rhombus evolution mode of configuration knowledge is discussed in this paper. The product model based on configuration knowledge is put forward in different levels to achieve the models dynamic evolvement and automatic upgrading. The evolving configuration knowledge drives the product model to evolve directly according to the rule of up-layer evolvement. Furthermore, a new configuration knowledge reuse and optimization technology is presented to inheriting and reuse the foregone configuration knowledge in the course of model evolvement. At last, the air separation equipment which is related with the project is taken as an example to illuminate that the presented model evolvement and configuration knowledge reuse technology are validity and practical.

A Design Method with Knowledge Modeling for Complex Product Based on Ontology

Innovation design for complex products is a difficult issue in the military manufacturing industry. Ontology may provide a feasible way to rebuild the design process for complex products via sharing and reusing of design knowledge. In this paper, a design method used in the innovation design process of the complex products with knowledge modeling is proposed. Knowledge modeling is realized through ontology construction by combining the cycling evolutional theory of constructing ontology and OWL (Ontology Web Language)-based knowledge representation. As a case study, the satellite is selected as one of the complex products. The application domain of the satellite ontology is analyzed. According to the analysis result, the knowledge structure of satellite ontology is put forward based on OWL. The application of satellite product design shows that the method can effectively organize and reuse the knowledge resources in the innovation design of complex product and help companies to create more competitive products based on the existing knowledge and experience.

Knowledge-reuse-oriented Product Modeling and Knowledge Management in Digital Design

Mostly product design knowledge and experience exists in design handbook or expert’s brain. During design process,designer has to refer to many handbooks and design materials,and design solution is hard to be reused. In order to deal with these deficiencies in digital design,this paper focuses on knowledge-reuse-oriented product modeling and knowledge management. Design knowledge is used to guide design process,and it is embedded into product model along with design process. Through analyzing design process,mechanical product knowledge is classified into four basic types that include calculation formula,design rule,engineering check and parameter spectrum etc. In order to manage and encapsulate design knowledge the concept of knowledge component(KCOM) is proposed. Design knowledge base can be organized as a hierarchy tree of KCOM. Knowledge reuse in KCOM level is the reuse of whole object in knowledge base,and knowledge reuse in item level is the reuse of basic knowledge type. Finally knowledge reuse approaches between knowledge base and CAD system is presented.

The Analysis of Unified Software Engineering Reuse （USER） Using Stable Analytical Model, Design of Structure and Architectural Patterns

The wearisome enthusiasm for making reasonable structures for programming reuse has gone before for whatever period of time that item has existed. Accepting particular intense structures are made for ensuring an abnormal state ofrensability from one suspect to the accompanying. The unavoidable slant for dares to ask for extensive alterations, paying little mind to being proposed for most noteworthy reusability, remains strong affirmation of this reality. Programming reusability makes examination of stable examination; arrange, likewise, plan outlines a range of tremendous interest. By extrapolating the unfaltering thoughts that use programming consistent quality show and the Knowledge Maps, we attempt to comprehend programming plans that do not require unrestrained modifications, changes or, then again augment. Such cases works kind of a structure, to the most recent inquiries could be incorporated rely on simply the development of the circumstance to which that is associated. Suitability of such methodology must be displayed in the paper.

African natural medicine:Toward a health preservation theory and systematization model for clinical applicationAfrican natural medicine and health preservation theory

All knowledge fields are founded on universal epistemologies and philosophies.This is evident in ancient Traditional Chinese and Ayurvedic(Siddha)medical systems,which are integrated into national health systems of China and India respectively.African natural medicines(ANMs)are not part of national health systems on the African continent because of a lack of systematization frameworks.This article explores classical medical systems drawn from ancient African and Chinese cosmologies.A qualitative research methodology was used to conduct in-depth interviews with 20 respondents selected using a purposeful sampling technique.The data were summarized into systematization frameworks for disease theories,etiology and pathogenesis,diagnosis and prognosis,and treatment including medicines and disease classification.The study findings revealed that in antiquity,Africa had systematic medical cosmologies,remnants of which are evident in current cultural health practices.Therefore,parallels can be drawn in relation to Chinese Taoist and Indian Tantric healing arts.Ancient Africans recognized Ra or iSithunzi(uMbhilini),which correspond to qi or prana and refer to energetic life force in Asian cultures.Shu and Tefnut(Nkomo weLwandle and Dungha Manzi)correspond to yin and yang or purusha and prakriti,the natural principles of polarised duality.The jing or oojas(physiological essences)and wu xing or pancha tattvas(five ele-ments and modes of nature)and their relationships with the zang and fu(five vital organs and visceral organs,respectively)also found their application in African medical cosmologies.The data revealed that ancient and contemporary ANM systems are based on the concept of con-sciousness(saa or ntu)and life force energy,ra.These cosmological concepts are predicated upon the Paut Neteru or Amathogo(archetypal forces)that prescribe properties to everything.On this basis,an African-Kemetic Health Preservation Theory was developed,which gives rise to African theories for disease etiology,pathogenesis,differential diagnoses,comprehensive prognosis,and holistic treatment regimens.In addition,we developed an uBu-Ntu bio-innovation model for integral research,inclusive innova-tion,local technology transfer,holistic enterprising,and conscious commercialization of African natural medicines.It is the intention of the authors to influence policy in the implementation of these theories,models,and frameworks for clinical application and socio-economic development.
