Risk factor, operational

As remarked in Approach 1, a potential complication with Expectation Model I lies in computing a suitable range of values for the operational risk factor 0j. Therefore, an alternative formulation of minimizing variance while adding a target profit constraint is employed for Expectation Model II ... 

Note that the index s and the corresponding set S is used to denote scenarios for the evaluation of the inner expectation term to distinguish them from the original index s used to represent the scenarios. Vs is weighted by the operational risk factor 02 e (0, oo). The formulation of Risk Model II is ... 

Similar to Risk Model II, the adoption of MAD is weighted by the operational risk factor 03 (0 < 03 < oo) in Risk Model III, to give the following formulation ...

The operational risk factors that cause disruption of maritime activities are due to port equipment failures, vessels accident/grounding, human error and cargo spillage (John, 2013). 

Because of the donor shortage appropriate selection of potential transplant recipients is of great importance. They should have an unacceptably high predicted short-term mortality or a very low quality of life despite aggressive medical therapy or after all other surgical therapies have failed. The candidate evaluation has to focus on pre-operative risk factors and on all additional factors that can negatively influence the post-transplant outcome. 

In considering these risk factors, there generally is little that can be done to shorten a FW line, and a long line may in fact be desirable where an oxygen scavenger is fed directly to the line because it will increase the DO contact time. To improve operating efficiency, however ... 

NOTE Under these low hardness but high MU demand circumstances, other risk factors also exist, especially in smaller boilers. Typically, the high MU water demand reduces the FW temperature, which permits the oxygen level to rise and thus requires additional sulfite scavenger to counter the increased risk of corrosion. Also, the requirement for BD is increased as TDS and SS levels also rise, so fuel and other operating costs increase accordingly.

Recognize at least three risk factors for post-operative wound infections. 

Risk factors for venous thromboembolism in pregnancy include increasing age, history of thromboembolism, hypercoagulable conditions, operative vaginal delivery or cesarean section, obesity, and a family history of thrombosis. 

The Study on the Efficacy of Nosocomial Infection Control (SENIC) analyzed more than 100,000 surgery cases and identified abdominal operations, operations lasting more than 2 hours, contaminated or dirty procedures, and more than three underlying medical diagnoses as factors associated with an increased incidence of SSI. When the NRC classification described in Table 48-1 was stratified by the number of SENIC risk factors present, the infection rates varied by as much as a factor of 15 within the same operative category. 

Hazard Assessment A process used to qualitatively or quantitatively assess risk factors to determine incident operations. 

A polymorphism can be a risk factor for an individual s health or life expectancy without impairing its reproduction. This appears to be the case for many common human diseases, which manifest themselves only after the generative period, so that evolutionary selection against such a trait cannot be operative. 

Therefore, in this approach, we develop Risk Model III as a reformulation of Risk Model II by employing the mean-absolute deviation (MAD), in place of variance, as the measure of operational risk imposed by the recourse costs to handle the same three factors of uncertainty (prices, demands, and yields). To the best of our knowledge, this is the first such application of MAD, a widely-used metric in the area of system identification and process control, for risk management in refinery planning. 

In this study, operational risk was accounted for in terms of variance in both projected benefits, represented by first stage variables, and forecasted demand, represented by the recourse variables. The variability in the projected benefit represents the solution robustness where the model solution will remain close to optimal for all scenarios. On the other hand, variability of the recourse term represents the model robustness where the model solution will almost be feasible for all scenarios. This approach gives rise to a multiobjective analysis in which scaling factors are used to evaluate the sensitivity due to variations in each term. The projected benefits variation was scaled by 0i, and deviation from forecasted demand was scaled by 02, where different values of 0i and 02 were used in order to observe the sensitivity of each term on the final petrochemical complex. The objective function with risk consideration can be written as follows ... 

Air supply systems must be designed to avoid the introduction of contaminants into air flows or into manufacturing areas local environmental conditions and associated risk factors. Air supply systems must be validated, operated, monitored, and controlled to deliver the required air quality. 

The Study of the Efficacy of Nosocomial Infection Control (SENIC) identified four independent risk factors for postoperative wound infections operations on the abdomen, operations lasting more than 2 hours, contaminated or dirty wound classification, and at least three medical diagnoses. Patients with at least two SENIC risk factors who undergo clean surgical procedures have an increased risk of developing surgical wound infections and should receive antimicrobial prophylaxis. 

Facilities and Equipment The technical experts who have an understanding of pharmaceutical science, risk factors, and manufacturing processes related to the product are responsible for defining specific facility and equipment requirements. The equipment must be qualified, calibrated, cleaned, and maintained to prevent contamination and product mix-ups. It is important to remember that the GMPs place as much emphasis on process equipment as on testing equipment while most quality systems focus only on testing equipment. Control Outsourced Operations Quality systems call for contracts with outside suppliers that clearly describe the materials or service, quality specification responsibilities, and communication mechanisms. 

Prior to considering the factory layout the designer must understand the risks to the production environment. These come from factors external to the plant, transmission media into the plant and internal factors resulting from operations within the plant. Table 8.1 details some examples of risk factors. Measures must be designed into the factory to eliminate or control all the risks to acceptable levels. 

Before a biotechnology process can be validated, it is essential to evaluate the inherent risk factors associated with the product source, raw materials, and processing operations. Furthermore, the analytical methods that allow characterization and validation of the process, as well as characterization of raw materi-...
