This paper considers the ruin probability of a kind of dual risk model with a threshold. We assume that the expenses with a constant rate c ,and the aggregate positive gains is a compound process. Besides, the gain size depends on the inter-arrival time. The integro-differential equations satisfied by the ruin probability are derived. The adjustment coefficient and Lundberg's inequality can be gotten...
Taking the electronic manufacturer Y as an example, this paper uses the stream-flow diagram to discuss the improvement process of such a production system. Based on the theory of lean value and the production process status of this factory, it describes the process with the visualized way and identifies the main kinds of waste. And working out the optimal output of products by the mathematical model...
This paper will discuss the in-depth details and experiments done to address the thermal resistance of Analog device thus paving the release and qualification of ONxx Shrink Die Technology hitting corporate drive of sure cost saving projects and bringing ON Semiconductor Philippines Incorporated to desire level of competitiveness. A closer look on the variables that contribute to these phenomena will...
Based on Chinese culture, this paper conducted an empirical research on the relationship between pay gap and firm performance to correct the former research results. Our research results indicated that under the incentive and constrain conditions of collectivism and great power distance, the relationship between pay gap of different organizational levels and firm performance was positive, which was...
This article takes listed companies of Manufacturing Industry as a sample, conducts the research to around the sample companies' earnings management change situation before and after the share-trading reform. The findings indicated: before and after the share-trading reform, because of the goal of listed companies' earnings management's varies, its controllable accrued profit of different type the...
Although asset growth has little effect on the behavior of the typical fund, funds should alter investment behavior as assets under management increase. We find that large funds diversify their portfolios in response to growth. Greater diversification, especially for large funds, is associated with better performance.
In this study, we discuss a theory on process for decision making under time constraint which is uncommon or asynchronous among two or bilateral decision makers. The problem on time constraint is to evaluate cost of time or value of the entire duration of a certain process for decision making. We propose a formula to compute cost of time by introduction of opportunity cost to its evaluation. We also...
Although ERP systems have lots of advantages for the organization, the ERP implementation is not straightforward and involves significant risks. Several studies have conducted to identify the critical success factors (CSFs) in the ERP implementation process, but most of them are lacking of systematic efforts to classify and evaluate CSFs. To achieve this aim, a structured methodology based on a fuzzy...
Study of the floating rule of technological innovation talents has become a hot issue nowadays because those talents play a key role in most enterprises. Based on the random model in the paper, we give a comprehensive evaluation and forecast for the flow of technological innovation talents. In the meantime we offer a reliable calculation model for the management of technological innovation talents...
Centralized purchasing is one of trends of procurement activity in supply chain surrounding. By a empirical analysis, this paper reveals supplier bidding mechanism and factors which decide price. Based on price attraction impedance, a gaming model is established between two suppliers as competitors each other, which shows factors of price, experience and supply ability is core competence for procurement.
ABC cost function model is established to calculate the reasonable and lowest cost of construction engineering, by using the idea of Activity-Based Costing (ABC) method that "resources consumed by activities and the products use up activities”. And then, the actual costs are calculated by combining with the accounting records and the calculation method of traditional cost. Now we get the actual...
Under frequency load shedding is implemented to restore power system frequency stability if system frequency drops below the operational set point during major disturbance such as lost of generation. Different countries/utility companies have their own philosophies in implementing the under frequency load shedding scheme. Generally, it is based on country/utility requirements, e.g. the overall power...
Putting forward a new method of power system medium-long term load forecast model establishment based on state space time-varying parameter equation theory, this work brings state variable into model observable for solution, which reflects the varying rules of equilibrium relation of variables and enhances the veracity for model forecast. The State Space time-varying parameter model describes the...
In this paper, we consider two abstract market models for designing demand response to match power supply and shape power demand, respectively. We characterize the resulting equilibria in competitive as well as oligopolistic markets, and propose distributed demand response algorithms to achieve the equilibria. The models serve as a starting point to include the appliance-level details and constraints...
Since B-to-B commercial websites play a decisive role in electronic business and trade, the evaluation and selection of them are very important. There have existed many methods for evaluation on commercial websites nowadays. But there are very few patterns of evaluation that are widely recognized and accepted so far. To tolerate subjective and objective factors that might influence evaluation results,...
Systems are secure if its have lower risks of system interruption. However, to determine the optimum level of security is an area where requires more research. In principle, the optimum level of security that a system provides is determined by the interaction between the cost of providing extra security and the value to consumers. The risks in energy system have to be quantified in order to identify...
This article defines the meaning of the risk of earnings information, select Index from a statistical sense, then according to the model theory, create a general assessment model, and do the parameters set bias and stability test. The results show that accrual earnings quality information can be the most reasonable measure of the risk of earnings information; the use of a general model assessment...
Data envelopment analysis (DEA) measures the relative efficiency of decision making units (DMUs) with multiple inputs and multiple outputs. DEA-based Malmquist productivity index measures the productivity change over time. The Malmquist productivity index based on DEA can be decomposed into two components: efficiency change index and technical change index. Through utilizing the principle of isoquant,...
In this study rational evaluation indicators were established to study Shanghai urban rail transit system, and the method of Extended Contributive Rule (ECR) was used to hierarchically analyze rail transit service quality, determines the different levels of service, and identifies various people groups' requirement difference in the service quality. It was aimed to objectively evaluate Shanghai urban...
In Western corporate finance theory, the Pecking order Theory suggests that when the company needs financing externally, it should firstly debt financing then equity financing. The reason is that the company will face more serious adverse selection in equity financing. However, Chinese enterprises usually have a strong preference on equity financing, this article estimates the intrinsic IPO value...
