Knowledge management strategy and its link to knowledge creation process

Abstract Knowledge has become to be considered as valuable strategic assets that can provide proprietary competitive advantages. It is more important for companies to distinguish themselves through knowledge management strategies. Without a constant creation of knowledge, a business is condemned to poor performance. However, it is still unclear how these strategies affect knowledge creation. Knowledge management strategies can be categorized as being either human or system oriented. This paper proposes a model to illustrate the link between the strategies and its creating process. The model is derived on the basis of samples from 58 Korean firms. The model depicts how companies should align the strategies with four knowledge creation modes such as socialization, externalization, combination, and internalization. It is found that human strategy is more likely to be effective for socialization while system strategy is more likely to be effective for combination. Furthermore, the survey result suggests that managers should adjust knowledge management strategies in view of the characteristics of their departments.

Implementing telecommunications infrastructure: a rural America case

Abstract Rural America, in the past, enjoyed telecommunications services at an affordable price. In recent years, however, the service in rural communities has deteriorated due to loss of its economic base and thus not able to upgrade to modern communication technology. This study examines ways of building an effective rural telecommunications network to facilitate rural development in an information-intensive society. The reorganization of the service for rural communities around a set of “hub” cities is considered; in addition, it develops a procedure for selecting “hub” cities from a multicriteria perspective. This essentially maximizes the utilization of available facilities and services, such as education, healthcare, transportation, and economic opportunities to benefit the maximum number of rural residents. The proposed framework is shown to serve as a positive aid in implementing rural area telecommunications infrastructure.

Managing user performance for a corporate network

A corporate network allows an enterprise to gain competitive advantages in an era of exploding needs for geographically dispersed information processing. A corporate network is made up of LANs linked by WANs. This paper provides a framework for its performance management. The framework, in the form of a life cycle, is broken down into demand forecasting, internetworking, data distribution, local configuration, performance evaluation, and system operation. By viewing a corporate network as an integrated entity, this framework replaces an ineffective and often ad hoc approach with structured and integrated management. A transaction delay model is proposed for managing user performance effectively. Furthermore, a design support system is developed and a real-life case is illustrated to demonstrate the applicability of the framework and model.

On the integrated inventory problem with items jointly replenished

Abstract In this paper, we examine a production inventory system of materials with items jointly replenished. It is proven that there exists an optimal policy that minimizes the associated annual inventory system cost. The special problem structure is exploited to develop an iterative procedure which provides a near-optimal solution. A numerical example is solved to illustrate the method.

Optimizing an integrated inventory system under deterministic demand

We seek a better understanding of an inventory system to simultaneously determine the optimal manufacturing cycle for the product and the optimal procurement quantities for the raw materials. We show that the problem under consideration is NP-hard with a unique optimum. We further show the relation of the problem to the other single machine problems. We conclude that any iterative algorithm for solving single machine problems can be employed to solve this problem. A typical inventory system is worked out to illustrate the method.
