极震区的地震动与潜在震源区内重大工程安全

潜在震源区是未来可能发生破坏性地震的震源所在地区 ,区内的地震属近场或“直下型” ,其地震破坏和地震动特征相应于已发生地震的极震区。近期国内外诸多强烈地震的实际资料和相关研究成果表明 ,直下型地震不仅地震峰值加速度大 ,且竖向和水平峰值加速度比值也有别于远场地震的统计关系。文中从极震区岩土体破坏、地震动特点及地震地质灾害等方面对潜在震源区内的重大工程问题进行了探讨

Optimal timing decisions for the introduction of new technologies

High technology industries, such as the communications industry, are characterized by frequent development of new technologies. These new technologies are often available before the capacities of existing facilities that use an old technology are exhausted. Whenever a new technology facility is introduced, a fixed set-up cost is generally incurred; however, the annual operating costs are often reduced. The optimal timing of the introduction of new facilities is therefore of interest.In this paper, we examine such timing decisions. The study was motivated by an application involving electronic plug-in units that enhance the operation of communication facilities. First, we develop optimal timing decisions for linearly growing demand. The analysis is then extended to nonlinear demand. For linear demand, one of two decisions is optimal: Either introduce the new technology immediately, or as late as possible. However, for nonlinear demand, these decisions may be nonoptimal.

An implicit enumeration algorithm for the passenger service planning problem: Application to the Taiwan Railways Administration line

In a passenger railroad system, the service planning problem determines the train stopping strategy, taking into consideration multiple train classes and customer origin–destination (OD) demand, to maximize the short-term operational profit of a rail company or the satisfaction levels of the passengers. The service plan is traditionally decided by rule of thumb, an approach that leaves much room for improvement. To systematically analyze this problem, we propose an integer program approach to determine the optimal service plan for a rail company. The formulated problem has a complex solution space, and commonly used commercial optimization packages are currently incapable of solving this problem efficiently, especially when problems of realistic sizes are considered. Therefore, we develop an implicit enumeration algorithm that incorporates intelligent branching and effective bounding strategies so that the solution space of this integer program can be explored efficiently. The numerical results show that the proposed implicit enumeration algorithm can solve real-world problems and can obtain service plans that are at least as good as those developed by the rail company.     

Exploring two explanations of loyalty in application service provision

While the application service provider (ASP) market continues to grow, it is fiercely competitive, and ASPs encounter difficulties in retaining customers and achieving long-term profitability. One stream of prior literature suggests that customer loyalty is driven by service quality, while another argues that loyalty is driven by partnerships between the firms. However, to date these competing explanations have not been tested together in the ASP context. This empirical study contributes to the literature by unifying these two previously separate streams of research on customer loyalty. Using a survey of 135 ASP clients, we find a significant relationship between the service quality perspective and the partnership perspective. We thus argue that service loyalty models ought to include both of these constructs in order to effectively explain service loyalty.     

An Activity-Based Costing decision model for life cycle assessment in green building projects

Carbon emissions are an increasingly important consideration in sustainable environmental development. In the green building industry, green construction cost controls and low-carbon construction methods are considered to be the key barriers encountered. Based on Corporate Social Responsibility (CSR) policy, management of carbon emissions from green building projects contributes to the acquisition of accurate building cost information and to a reduction in the environmental impact of these projects. This study focuses on the CO₂ emission costs and low-carbon construction methods, and proposes a 0–1 mixed integer programming (0–1 MIP) decision model for integrated green building projects, using an Activity-Based Cost (ABC) and life cycle assessment (LCA) approach. The major contributions of this study are as follows: (1) the integrated model can help construction company managers to more accurately understand how to allocate resources and funding for energy saving activities to each green building through appropriate cost drivers; (2) this model provides a pre-construction decision-making tool which will assist management in bidding on environmentally-friendly construction projects; and (3) this study contributes to the innovation operation research (OR) literature, especially in regard to incorporating the life cycle assessment measurement into construction cost management by utilizing a mixed decision model for green building projects.
