Priorite

Moving responsibility for the force computation away from the patches required a move away from pure message-driven execution to dependency-driven execution in which patches control the data (atomic coordinates) needed for compute objects to execute. A compute object, upon creation, registers this dependency with those patches from which it needs data. The patch then triggers force calculation by notifying its dependent compute objects when the next timestep s data is available. Once a compute object has received notification from all of the patches it depends on, it is placed in a prioritized queue for eventual execution. 

Another significant benefit of a LIMS is the improvement of the overall quaUty of the laboratory. In the case of a laboratory, quaUty is defined as satisfying customer needs in the areas of accuracy, reUabiUty, clarity, and timeliness of analytical information. LIMS can enhance quaUty in a number of ways, eg, in checking conformance to requirements, in organizing and prioritizing work to ensure timeliness, in measuring laboratory performance in areas of technical quaUty and efficiency so as to provide continuous improvement, and in helping the laboratory to communicate clearly, completely, and consistendy (16).

Pareto charts often illustrate the principle that 80% of the effect is the result of 20% of the causes (49). Thus these charts are valuable in prioritizing improvement activities. Identifying and correcting the 20% often results in an 80% improvement in the measured effect. 

Influence diagrams can be used with the strategy tables to identify factors or variables that create uncertainty in assessing the value of various options. Issues can be quaUtatively prioritized in selecting the best path to generate value for the business.

Introduction Theprevious sections dealt with techniques for the identification of hazards and methods for calculating the effects of accidental releases of hazardous materials. This section addresses the methodologies available to analyze and estimate risk, which is a function of both the consequences of an incident and its frequency. The apphcation of these methodologies in most instances is not trivial. A significant allocation of resources is necessary. Therefore, a selection process or risk prioritization process is advised before considering a risk analysis study.

Once the PSSR team is satisfied with their review, a form such as Example 4-1, Pre-startup Safety Review Completion Form can be used to capture their approval for startup. For simple changes, this one-page form may be all that is required. In the case of extensive modifications, a detailed checklist of items examined by the team may accompany this form. It could include unsatisfactory findings as well as respective recommendations. If recommendations were made, these must be prioritized. Some may need to be resolved before startup others may be appropriately addressed after processing has begun. Some items reviewed by one company for extensive modifications and logged in addition to the one-page form are ...

The so-called Q7 tools and techniques, Cause and Effect Diagrams, Pareto Analysis, etc. (Bicheno, 1994 Dale and McQuater, 1998 Straker, 1995), are applicable to any stage of the product development process. Indeed they support the working of some of the techniques mentioned, for example using a Pareto chart for prioritizing the potential risks in terms of the RPN index for a design as determined in FMEA (see Appendix III).

If the information collected as you develop the lAQ profile indicates that you have one or more lAQ problems, prioritize these problems by considering the apparent seriousness of their consequences. For example, combustion gas odors demand a more rapid response than thermostats that are out of calibration. 

Once the conceptual model is operating, it can be utilized to help develop a technically sound, cost-effective recovery and treatment system. Potential uses for a conceptual model include provision of continual upniates of project developments, provision of a yardstick to measure what has been done and what needs to be done, and helping prioritize areas for Corrective Action. Ultimately, the principal use for a conceptual model is to help determine what Corrective Actions or alternatives are applicable to the site. 

Judgement and concerns of the community can be entered into the ranking and prioritization for community hazards. 

A number of risk importance measures have been defined for the interpretation of PSAs and for use in prioritization of operational and safety improvements. Some of these measures are similar to sensitivity defined as the total derivative (equation 2.8-1). 

This section describes how both hypothetical and real accidents are analyzed. These methods varying greatly in complexity and resource requirements, and multiple methods may be used in an analysis. A simple method is used for screening and prioritization followed by a more complex method for significant accident scenarios. Some methods give qualitative results more complex methods give quantitative results in the form of estimated frequencies of accident scenarios. The process systems in Figures 3.3.1-1 and 3.3.1-2 are used in the examples.
