  • Publication number: 20110021858
    Abstract: A process for the double-bond isomerization of olefins is disclosed. The process may include contacting a fluid stream comprising olefins with a fixed bed comprising an activated basic metal oxide isomerization catalyst to convert at least a portion of the olefin to its isomer. The isomerization catalysts disclosed herein may have a reduced cycle to cycle deactivation as compared to conventional catalysts, thus maintaining higher activity over the complete catalyst life cycle.

  • Publication number: 20090112663
    Abstract: A computer implemented method and a computer system implementing the method of a business process transformation wizard leads a business analyst through a series of steps to invoke business transformation patterns, in order to analyze the results of those processes. The wizard first prompts the business analyst to specify business objectives of process transformation. Required parameters are added to the business process model guided by the business process transformation wizard until the business process model is completed. Once the model is completed, the wizard prompts the business analyst to select transformation techniques or patterns for optimizing process parameters and, for each selected transformation pattern, optimizes process parameters using a selected optimization technique.

  • Publication number: 20080215401
    Abstract: Risk in business management is analyzed based on a probabilistic network approach which quantifies the impact of operational risk on financial metrics such as Value-at-Risk (VAR) and/or Potential Losses (PL). This approach provides further capability to determine the optimal placement of one or more countermeasures within a system to minimize the impact of operational risks.

  • Publication number: 20080208660
    Abstract: A system and method for analyzing and managing business performance by designing and evaluating the performance of a business process model comprising a flow of business tasks and artifact sources that generate business artifacts. Business processes may be parsed to identify transformation opportunities meeting transformation conditions specified in a transformation knowledge. One or more identified transformation opportunities may be adopted, and parts of the process may be transformed according to transformation rules specified in a transformation knowledge. Analytics and computer simulation may be employed to evaluate business performance metrics of each of said transformed business processes. Iterative changes may be made to said business processes to manage business performance, reiterating transformation and evaluation steps until a satisfactory business process model is obtained.

  • Publication number: 20080183562
    Abstract: A stabilization methodology and system component in Business Activity Monitoring and Management systems. This enables firms to use Business Activity Management (BAM) systems to manage business activity by only responding to monitored data when the overall business performance can be improved. This enables firms to identify appropriate tradeoffs between potentially conflicting objectives while meeting business objectives. Information from BAM systems are analyzed based on models of the business process and different information filter criteria are assessed for their impact on business performance indicators. Based on this, a filter criterion is chosen which is executed by an information filter. The outputs from the information filter are used as the basis for deciding the inputs for business process execution.

  • Publication number: 20080162232
    Abstract: A methodology for business process analysis and optimization. This enables firms to analyze business processes using stochastic processing network models to estimate process key performance indicators. Based on these indicators, alternate process models can be further developed and analyzed, in order to optimize business objectives. The analysis methodology can be used for business process design (at design time) and for business process management (at run time).

  • Publication number: 20070208600
    Abstract: A computer implemented method and a computer system implementing the method provide enterprises with pre-emptive/proactive operational risk management. First, historical data on the occurrence of operational risk events and other internal business/external metrics and indicators are collected. This is followed by construction of a model for correlating the risk events with internal and external metrics and indicators. This can result in the estimation of the probability of occurrence of risk events and a model for the severity of a loss event (in termns of, say, dollar amount) as a function of the various variables that are related to or have leverage on the business operation. The Key Risk Indicators for the business are then identified based on the model. Following this, the identified key risk factors are forecasted for future time periods and used to identify early warnings of risk and is further validated.
