IT governance has become an important concern for business, receiving great attention from both practitioners and academics. Although some authors have stated that effective IT governance is crucial for any organization to achieve its corporate goals, little academic research is available that empirically supports the assumptions about the factors that determine the effectiveness of IT governance...
This study develops a methodology for re-scheduling the economic purchases of energy in the spot market and in the bilateral contracts through bilateral contract adjustments with corresponding penalties. The methodology minimizes the total monthly energy cost incurred by a distribution company by optimally allocating the energy purchases between spot market and bilateral contracts. It considers the...
For companies with large sales forces whose sellers approach business clients in teams, the problem of allocating sales teams to sales opportunities is a critical management task for maximizing the revenue and profit of the company. We approach this problem via predictive and prescriptive analytics, where the former involves data mining to learn the relationship between sales team composition and...
This paper deals with the implementation of the mathematical model for the Products Allocation Problem in a multi-layer warehouse. The model has been applied to identify the optimal warehouse configuration for a company operating in the sector of production and distribution of sports equipment and sportswear, with the main goal of minimizing the material handling costs. Cost analysis have been carried...
Government intervention in transition period is one of the critical influential factors of merger efficiency, and there is much less research in this field. This paper deeply analyzed the effect of government intervention on merger efficiency from the multidimensional perspectives of the executive level of government intervention, transferring of state-owned control right and changing of final controller...
Different from the existing literatures mainly focus on the value effect of corporate diversification, our paper analysis and examines how corporate diversification affect financial liquidity, and wheher there exists difference under different property condition. The results show that, corporate diversification decrease cash holdigns in general, which indicates that the diversiciation strategy and...
Risk allocation is an important issue in Principal-agent theory. This paper researches on a failed motivation mechanism of H Optoelectronic Co., Ltd., and then based on Principal-agent theory. And we analyze the ratio of risk allocation, which affect the enterprise's performance and the employee's performance, between the enterprise and the employee in motivation mechanism. And then we expect get...
The creation of the Shenzhen small and medium-size enterprise (SME) board makes small and medium-size firms raise funds in the stock market, to solve the problems of their own funding needs. High initial public offerings (IPO) underpricing appears on the listed companies' first listing day in SME board, and mean of IPO Underpricing remains more than 100% for years. China's capital market is gradually...
In competitive power system all services including transmission loss need to be priced properly to improve efficiency. Though a generally acceptable method for transmission loss allocation is yet to be developed, the proportional allocation technique has wide acceptance. But this method is not directly applicable to transaction based power system due to the absence of a proper transaction based power...
It's an indisputable fact that credit policy inclines to state-owned enterprises in China. Based on it, by using a sample of 1399 A-share listed companies over the year 2009 to 2011, we investigate the difference of credit rationing and cash efficiency between state-owned and private enterprises. Results show that the existence of “Bank Power” forces enterprises obtaining credit to increase the amount...
For the need of sustainable development, the importance of the reverse collection and remanufacturing has been widely recognized in the literature and in practice. In this paper, we analyzed three reverse channels extensively used in the remanufacturing practice, i.e. retailer collection, manufacturer collection and third party collection. The results address that the choice of single one reverse...
The overview of the new generation of multi-agent systems for real time enterprise resource management is presented. The developed solutions are based on bio-inspired multi-agent technology which is applied for allocation, scheduling and optimization of resources in real time. Developed methods and tools allow to improve the efficiency of resource utilization and quality of client service, reduce...
In this paper, we consider a smart grid incorporating numerous devices. In order to manage the energy distribution, we propose an algorithm that employs the group bargaining concept of game theory to efficiently allocate electricity resources among these devices. First, we divide the devices into non-overlapping groups, and allow devices to bargain both within and across groups. Second, we regard...
Along with the gradual maturity of Pickup and Delivery Customers to Airport service (PDCA), transactional management can't meet the needs of Flight Tickets Sale Companies (FTSC) which implemented PDCA. In fact, company urgently demands statistical information from the accumulated data of service to make correct decisions. Therefore, the aim of the research is to evaluate and analyze the historical...
Engineering and installation processes are one cost driver within the life cycle of a technical system. Especially within international projects crossing country borders, the cost distribution and the cost allocation are challenges for the success of the technical system. The engineers usually responsible for the decisions where and by whom an engineering activity has to be executed within the engineering...
We studied file size distributions from 65 customer installations and a total of nearly 600 million files. We found that between 25% and 90% of all files are 64 Kbytes or less in size, yet these files account for less than 3% of the capacity in most cases. In extreme cases 5% to 15% of capacity is occupied by small files. We used this information to size the ratio of SSD to HDD capacity on our latest...
Optimal utilization of human resources contributes to achievement of the aims of IT department and also of the entire company. Organizational Structure of IT department should be designed on the base of IT Service Lifecycle. IT personnel should support the IT Services in all stages of their Lifecycles. The paper is focused on the method describing transformation of the organization structure of IT...
Nowadays, the human factor is considered as the key element of flexibility and performance of manufacturing systems. Resources in production system are basically machines and operators. Most of the scheduling work consists in assigning tasks to a set of resources by defining their order and their starting execution dates and finishing dates. The objective is to find an optimal schedule satisfying...
The research paper presents the methodology used to develop decision algorithms for order holons. Two algorithms are presented in this paper. The algorithms model an actual job allocation system and a conceptual one for the formation of networks of manufacturers. The first algorithm is derived from an industrial case study. The second algorithm exploits the use of multiple flexibility parameters to...
Untimely or uncontrolled release of work orders into production creates variance in production and in turn leads to high work-in-process and increased average throughput time, high conversion rate and unbalanced production line. In the HMLV manufacturing environment (e.g. Precision Engineering industry), the massive product mix, low production quantity, and the multitude of production constraints...
