International Journal of Engineering and Technical Research (IJETR) ISSN: 2321-0869 (O) 2454-4698 (P), Volume-7, Issue-2, February 2017 32 www.erpublication.org Abstract Today, information has become more important. Even data, information and knowledge are often used as if they have same meaning. This problem raises difficulties in engineering. It is necessary to exist a knowledge management system to avoid increased costs, waste of time and increased errors. Knowledge management is a comprehensive process of knowledge creation, knowledge validation, knowledge presentation, knowledge distribution and knowledge application. In this paper, knowledge management has been explained in general. Then as an example for this study, machining system has been considered, and an application of Knowledge Management in engineering has been attempted to explain. The paper proposes a knowledge management to achieve a competitive control of the machining systems. The model can be used by the manager for the choosing of competitive orders. Index Termscompetitive control, information technology, knowledge management, machining system, marketing knowledge I. INTRODUCTION The recognition of the Knowledge Management (KM) imperative will provide an impetus for enterprise to understand and nurture their knowledge resources and activities. KM has assumed a broad range of meanings from its inception; however, most of the published material remains ambiguous and provides little empirical evidence to support a specific definition for the knowledge management concept. KM has been acknowledged as being important to competitive advantage and organizational progress. Thus, a clear understanding and agreement about KM should prove to be of great value for enterprises. As enterprises strive to create a competitive advantage with their products and services, they continue to contemplate the KM concept and the impact on organizational success. In a effort to define KM, enterprises must determine which A general definition has been ‘getting the right information to the right people at the right time’ in order for them to make better decisions. Knowledge management implementation is an advantage for the enterprise from viewpoint of the competitiveness. The new knowledge will be used both in the enterprise management and to develop new products and new services or make important changes in the business decisions. By means of learning, the enterprise which uses the knowledge able to adapt and respond continuously to the changes of the business environment.

An important goal of KM is seen to be the sharing of best practice. So, by the improving the flow of knowledge through the enterprise can be obtained the following benefits: - the sharing of the best practice around business processes; - the ability to respond more effectively to customer demands. Due to technology facilitates the rapid exchange of information, the pace of acquisition is growing exponentially in both large and small enterprises. The vast amounts of knowledge possessed by the enterprises are spread across countless structured and unstructured sources. To improve processes and bring new products to the market faster and more cheaply, the enterprises have to identify, make available and apply this knowledge. It is necessary to exist a knowledge management system and coordination between disciplines to avoid increased costs, waste of time and increased errors. Thus, information must be understood, organized and transformed for problems solving. Consequently, information transformed in product is knowledge and coordination of this kind of knowledge is made by means of knowledge management. The manufacturing industry faces the challenge of responding quickly to the ever-changing requirements of customers. It is necessary that in these high competitive environments, enterprises to control production system dynamics of such as: - change in the product types and variants; - change in the production quantities. Enterprises have to develop and implement more responsive and flexible manufacturing systems based on knowledge. By this way, they can respond to outgoing and difficult to predict change in production requirements and make products with high quality, low cost and fast delivery. The market dynamics is further passed to the mode of operation and management. In a knowledge-based society and economy, operations such as determining the relevant information and aggregating them into pieces of knowledge must be automated, because in such a complex and unpredictable environment, they are indispensable tools for creating, searching and structuring knowledge. The interaction between the economic environment and the manufacturing system is a major source of knowledge about the economic environment and the manufacturing system themselves [3].Paper has the following structure: section II explains data, information and knowledge terms, section III presents knowledge management in engineering, section IV illustrates knowledge management of machining system, section V contains a case study and section VI summarizes the main conclusions achieved. II. DEFINING DATA, INFORMATION AND KNOWLEDGE Defining data, information and knowledge is difficult. It is possible to distinguish between data, information and knowledge on base of external means or from the perspectives of the user.
