For a continuous revenue increase, a new scheme to increase sale volume is a necessity. This new scheme is based on a revaluation of the customer value for the sake of the future of a company. The concept and use of CRM and OLAP(On-Line Analytical Processing) are introduced in this report. The effectiveness of OLAP-based CRM is demonstrated through a case study of a typical retail company. The research suggests the need for the establishment of a marketing strategy to build a long-term relationship with individual customers. The needs for a scientific and systematic analysis of the industry, competitors and customers are elaborated.

The research of scheduling algorithms for operating the facility of exhibition and convention can be hardly found in published papers. This study is to find problems in the process of operating the facility of exhibition and convention and to develop the scheduling algorithm satisfying those problems. The scheduling algorithm of this paper is developed through constructing the mathematical model and analyzing the mathematical structure of variables and constraints in that model. The scheduling algorithm developed in this paper consists of the first stage of scheduling, the second stage of feasibility routine and the third stage of improving scheduling results. Some experimental results are given to verify the effectiveness of the scheduling algorithm developed in this paper.

In this paper, we construct a new approach of affine scaling interior algorithm using the affine scaling conjugate gradient and Lanczos methods for bound constrained nonlinear optimization. We get the iterative direction by solving quadratic model via affine scaling conjugate gradient and Lanczos methods. By using the line search backtracking technique, we will find an acceptable trial step length along this direction which makes the iterate point strictly feasible and the objective function nonmonotonically decreasing. Global convergence and local superlinear convergence rate of the proposed algorithm are established under some reasonable conditions. Finally, we present some numerical results to illustrate the effectiveness of the proposed algorithm.

This study determines whether or not firms can achieve high productivity growth through external technology acquisition. It also identifies the key factors affecting adopting firms' productivity growth by employing the Malmquist productivity index (MPI) methodology, which features computational ease, low data dependency, and decomposition of productivity growth into technical efficiency change and technical change. Results showed that the effects of productivity growth arising from technology transfer became stronger over time. Moreover, patent transfer guaranteed firms' productivity growth, but no evidence was found that factors such as age and size could increase productivity. Finally, cultural similarity could be another factor conditioning the effectiveness of technology transfer in the productivity of adopting firms.

Purpose - This theoretical study develops practical recommendations for implementing a quality management system (QMS) in Kazakh organizations to ensure the effectiveness and safety of products and services. We discuss the improvement of Kazakhstan's quality standards based on the requirements of ISO 9000. Research design, data, and methodology - We provide methods for improving the quality standards system, ranging from research and development to the sale of products. We also propose to establish a special quality systems award to motivate enterprises toward product quality improvement. The study's methodological basis included Kazakhstan's legislative and regulatory Acts, and international and national standards defining QMS requirements for scientists worldwide to develop and implement a QMS for enterprises. Results - Aligning the QMS reduces Kazakh companies' costs for the detection and correction of defects, and the external and internal loss caused by the defects. Effective QMS also reduces management costs. Conclusion - This article can help increase the transparency of organizations for their leaders and (if necessary) the external environment, and improve the accuracy, quality, and timeliness of decision-making.

In this research, we propose a method to extract scallop areas in seabed images in order to construct a system that can measure automatically the number, size, and state of fishery resources, especially scallops, by analyzing seabed images. Our algorithm is based on information about the hue, characteristic pattern, and the shape of scallop shells. The effectiveness of the proposed method is illustrated through an experiment.

Many organizations are facing larger and more frequent changes in the current economic and managerial environment. And what is more, change is supposed to be a business as usual. Considering the importance of change management process and the organizational competency to rapidly and successfully change, in this study the components of change management maturity(CMM) was selected such as the leadership, communication, resistance, people culture factor, methodology, functional group, and change review. And information system performance affected by CMM is confined to the efficiency and effectiveness of information systems. Some results from the verification of research hypotheses and the analysis of the most appropriate model was drawn out. The result of this study can be applied to all organizations which plan to manage more successful change and implement more effective information systems.

With the advent of electric power systems moving to a deregulated retail electricity market environment, calculating distribution service tariffs has become a challenging theme for distribution industries and tariff regulators. As distribution business remains as a monopoly, it is necessary to be regulated. And as multiple distribution companies compete with each other, it would be efficient to adopt competition to the determination of distribution service tariffs. This paper proposes a method to calculate distribution service tariffs using yardstick regulation, which can lead to competition among multiple distribution companies. The proposed method takes into account not only recovering revenue requirements but also the advantages of the yardstick regulation based on long-term marginal costs of distribution network expansion algorithms. A computer simulation is carried out to illustrate effectiveness of the proposed method and it is estimated that the algorithm can be applied to compute the distribution service tariffs under retail electricity markets.

Purpose - This study sought to discuss definitions of organizational culture taking into consideration different views, and the historical and philosophical elements of organizational culture. Research Design, Data, and Methodology - This paper is a relatively conceptual study that has attempted to define organizational culture, a topic that has been debated among scholars and practitioners. Various studies in the literature related to organizational culture have been reviewed in an effort to reduce the complexities and ambiguities in definitions of organizational culture. Results -This study summarized and synthesized different studies related to organizational culture, and identified the main streams for defining organizational culture as being from the historical and philosophical elements of organizational culture. Conclusions -The concept of organizational culture continues to be an important factor affecting organizational effectiveness and initiating organizational development. However, the definition of organizational culture has not been well-established. In this sense, this paper seems to be significant and meaningful as it attempts to define organizational culture from different perspectives.

We examine the effectiveness of the conventional (Q, r) model in managing production-inventory systems with finite capacity, stochastic demand, and stochastic order processing times. We show that, for systems with finite production capacity, order replenishment lead times are highly sensitive to loading and order quantity. Consequently, the choice of optimal order quantity and optimal reorder point can vary significantly from those obtained under the usual assumption of a load-independent lead time. More importantly, we show that for a given (Q, r) policy the conventional model can grossly under or over-estimate the actual cost of the policy. In cases where a setup time is associated with placing a production order, we show that the optimal (Q, r) policy derived from the conventional model can, in fact, be infeasible.
