Coal seam gas drainage is affected by many factors which may be generally divided into two groups, geological factors and operational factors. Studies conducted in the Bulli seam found geological factors had a dominant impact on coal seam gas drainage while operational factors had a secondary impact, affecting the amount of optimum gas drainage performance achieved within the limitations impose...

We extend critical success factors (CSF) methodology to facilitate participation by many people within and around the organization for information systems planning. The resulting new methodology, called “critical success chains (CSC),” extends CSF to explicitly model the relationships between IS attributes, CSF, and organizational goals. Its use is expected to help managers to (1) consider a wi...

In an attempt to define a generic way to include human factors in a simulation of military operations HFM 128 suggested to break the causal chain between human factors as input and operational outcome into three components: a) human factors science based models to calculate state variables of the human, b) Performance Shaping Functions (PSF) to quantify the effect of states on individual perfor...

what are the main success factors of microfinance institutions in providing financial services to poor people in a sustainable manner? in this article we try to answer this question. in one hand, we analyze the core compatibility between microeconomics of asymmetric information, transaction cost and risk, and new different operational mechanisms applied by microfinance institutions. on the othe...

The life cycle cost of a system is influenced by its maintainability. Maintainability is a design parameter, whose operational conditions can affect it significantly. Hence, the effects of these operational conditions should be quantified early in the design phase. The proportional repair model (PRM), which is developed based on the proportional hazard model (PHM), can be used to analyze mainta...

Operational risk has been great challenges of commercial banks and financial institutions since losses caused by operational risk have been significantly greater than ever before. In order to control and manage operational risk better,clear awareness of the operational risk conduction mechanism is helpful to further understand the whole dynamic process of the risks affecting the business.
