What-if scenario

Confirmed changes or what if scenarios are easy to plug in and a new time line or critical path can be printed. 

Here again, no precise instructions can be given because each situation will demand a tailored approach. Note Numerical simulation in many ways resembles the what-if scenario technique available in spreadsheets programs. Several programs supplied with this book allow the reader to play with functions and noise levels.)... 

V Process hazard analysis (PHA) must be performed by a team of experts, including engineers, chemists, operators, industrial hygienists, and other appropriate and experienced specialists. The PHA needs to include a method that fits the complexity of the process, a hazards and operability (HAZOP) study for a complex process, and for less complex processes a less rigorous process, such as what-if scenarios, checklists, failure mode and effects analysis, or fault trees.

Another important reason for using multiple scenarios is to represent major sources of variability, or what-if scenarios to examine alternative assumptions about major uncertainties. This can be less unwieldy than including them in the model. Also, the distribution of outputs for each separate scenario will be narrower than when they are combined, which may aid interpretation and credibility. A special case of this occurs when it is desired to model the consequences of extreme or rare events or situations, for example, earthquakes. An example relevant to pesticides might be exposure of endangered species on migration. This use of multiple scenarios in ecological risk assessment has been termed scenario analysis, and is described in more detail in Ferenc and Foran (2000). 

Three What If scenarios are now presented using the data discussed in Example 1. These include (1) changing class volume, (2) choosing an incorrect rank, and (3) mislabeling samples in the training set. 

As illustrated, based on simulation results, using the plotted graphs and screens, management can easily evaluate different design alternatives, machine and human behavior models, control systems, sensory feedback processing, and the need of a balanced server architecture, and even investigate what if scenarios further, without committing to major upfront investment. 

Realistic predichons of study results based on simulations can be made only with realistic simulation models. Three types of models are necessary to mimic real study observations system (drug-disease) models, covariate distribution models, and study execution models. Often, these models can be developed from previous data sets or obtained from literature on compounds with similar indications or mechanisms of action. To closely mimic the case of intended studies for which simulations are performed, the values of the model parameters (both structural and statistical elements) and the design used in the simulation of a proposed trial may be different from those that were originally derived from an analysis of previous data or other literature. Therefore, before using models, their appropriateness as simulation tools must be evaluated to ensure that they capture observed data reasonably well [19-21]. However, in some circumstances, it is not feasible to develop simulation models from prior data or by extrapolation from similar dmgs. In these circumstances, what-if scenarios or sensitivity analyses can be performed to evaluate the impact of the model uncertainty and the study design on the trial outcome [22, 23]. 

The foremost benefit of spectral simulation tools is to simplify the exploration of various "what if " scenarios in MRS experimentation. Spectral simulation is much like the first "killer app" for the personal computer, VisiCalc. That program enabled users, originally in business but eventually in a wide variety of fields, to model and ask "what if" questions about a range of mathematical and business trends. It simplified laborious pencil and paper calculations that took hours or days into electronic operations that took seconds. As a PC application, no longer was it just large corporations with specialized software and mainframes who could afford to mathematically model business trends. The introduction of a...

An excellent example of a decision trees is shown in Figure 27.8. This example outlines the IND regulatory review and approval process. Similar decision trees are developed by project teams within the biopharma-ceutical industry. Project teams are now being asked not only to construct decision trees, but to develop contingency plans based on "what-if" scenarios far in advance of the next decision points. The goal is to ensure that the project will not lose forward motion in the event of a "no" decision that requires rework or another loop through the project cycle, or a decision by the PMT that resources for a particular project are more urgently needed for another project. 

The Process Hazards Analysis team takes a systematic approach to identify potential process hazards and to document them [51]. The Hazardous-Operation Analysis (Haz-Op) is a method by which the process procedures, process and instrument diagrams, and process flow diagrams are evaluated for operability and safety. Fault-Tree Analysis (FTA) is also a method, which investigates the assessment of what-if scenarios and failure conditions. The outcomes of this analysis are recommendations for the col-...

The successful development of a new pharmaceutical product requires careful planning of various activities and resources, as well as tracking the project s progress. A small project is not difficult to monitor manually however, multiple projects benefit from an automated tool to support the planning process as well as the monitoring of various activities. In addition, these systems will help develop what if scenarios for the resources in the new projects as well as help to terminate the projects. Several project management systems currently available on the market are designed to fulfill these needs. These systems are available for all types of computers—from personal computers to mainframes. 

This software is available commercially for almost all types of computers and is becoming a valuable tool to solve mathematical problems. The data are entered in the form of tables, the mathematical formulae are defined, and at the push of a button the answer is obtained. The user can easily modify the formula as well as add rows or columns of data and obtain the results easily and quickly. As such, this software enables the user to determine what-if scenarios for the problem at hand. It also is extremely valuable in helping the pharmacist compute percent composition and the amount of each ingredient necessary for preparing different strengths of dosage forms. In addition to providing the computational ability, the software also enables the user to prepare data and information in the form of tables and plots.

The Value of Eco-Efficiency Analyses. The value of the eco-efiiciency analysis tool, apart from its description of the current state, results from the recognition of dominant influences and the illustration of what if... scenarios. The stability of the results is verified by means of sensitivity analyses in every project. Underlying assumptions as well as system boundaries and societal weighting factors are varied and checked within realistic ranges. The results of an eco-efficiency analysis make it possible to identify weaknesses in products and processes over the entire lifecycle. This allows us to identify factors with significant optimization potentials. 

The model lends itself to discussion of what if scenarios, and to this end a simulation tool ° has been produced which enables managers to probe the relationship between current or projected target portfolios and chemistry design streams (Figure 14.8).
