At one global fine chemical producer, strict gate-keeping, i.e., separation of project execution from task definition, followed by the application of clear technical and economic criteria, led to a significant reduction of maintenance activities. In the end it proved possible to reduce capital expenditure for maintenance-related... 

When new drugs and drug-delivery systems are developed in the laboratory, the correlation of the necessary production equipment may be very difficult indeed. For example, the shear needed to create the desired particle size of an emulsion with the help of laboratory equipment may pose serious problems in the selection of plant equipment necessary to reproduce the attributes of the product. Recording the speed of a laboratory mixer is not sufficient by itself for this task definition of the operating principle and equipment design is necessary to accomplish the task. 

It supports elemental task definitions that are parameterized, modular, and reusable without dependencies on other tasks. 

It is also interesting to consider various types of overall systems made up of combinations of the devices in Table I, rather than just the specific devices or unit systems. Table III shows the performance of several overall energy systems. (Note that the Htj values presented in Table III reflect to a large degree the task definitions which resulted in Figure 3 and therefore are somewhat lower than those for Table I which were used for Figure 2.)...

Other potential conflicts may arise with R D personnel and engineers, as embedded lead users tend to go b ond their original task definition and bring their own ideas to R D s attention. This may lead to problems if R D personnel is reluctant to use knowdedge that is not generated in R D. My findings indicate that trust relationships between embedded lead users and developers can alleviate these potential conflicts and result in fruitfid collaboration. 

The example used below is a typical task definition and was realized in 1980-1982 in Croatia. A salt plant has to be designed for a production capacity of 9 t/h table salt. A part of that quantity (2.5 t/h) shall be recovered as granular salt with an average particle size d > 2 mm, whereas the rest (6.5 t/h) shall be produced as PDV (pure dried vacuum) salt with a mean particle size of around 0.4 mm. The purity of the vacuum salt had to be minimum 99.7% NaCl. 

From an Ergonomic perspective there are many factors that may be taken into account regarding workplaces analysis such as the interaction human being machine, personal factors, tasks definitions, tasks needs, work environment, among others.

There are several important partial results. (1) Definition of quality of the CT-data in relation to the imaging task, including a model of the X-ray paths and how it is used to predict the optimal performance. (2) A model and method to determine how the information of the imaged object transfer from the detector entrance screen through the detector chain to CT... 

The three-part draft of the radioscopy standard pr EN 13068 is ready for the necessary european inquiries. This standard covers the requirements placed on the imaging system, the checking procedures as to the performance of the entire system and also the specifications of user guidelines for certain inspection tasks. The standard remains open to the definition of new inspection classes for future application cases. 

An inventor may estabHsh utiHty by providing several working examples which disclose preparation, appHcation, and even some or all of the benefits of the invention. UtiHty may also be substantiated by merely disclosing several appHcations for the invention. One method of determining the breadth or scope of an invention is to define the invention by only those elements essential to performing the intended task. This definition should then become the broadest cl aim of the patent appHcation. 

Definition 2 Knowledge-based systems are computer programs that encode symboHc knowledge about domains and tasks, and solve problems by manipulating this knowledge using quaHtative techniques. 

Therefore the basic task of scientific work is development of sensitive, selective and simple methods of quantitative definition of the total contents of the alkaloids in the expert-criminal objects with the help of electrochemical methods of the analysis. 

Control of metalloid content in natural objects, foodstuff and pharmaceuticals is an important task for modern analytical chemistry. Determination of elements such as Arsenic is necessary for evaluation of object toxicity, since their content in environment may exceed MCL (maximum contaminant level), posing hazard to human health. Elements such as Selenium in definite doses are healthy, but in greater quantities they produce toxic effect. 

Establishing the physical and analytical boundaries for a QRA is also a difficult task. Even though you will provide input, the scope definition will largely be made by the QRA project team. Defining the physical boundaries is relatively straightforward, but it does force the QRA team to explicitly identify and account for interfaces that may significantly affect the QRA results. Eor example, analysts often treat a connection to a power supply (e.g., a plug) or a feed source as a physical boundary yet, loss of power or contamination of the feed must be considered in the QRA model. 

Before setting about the task of developing such a model, the product development process requires definition along with an indication of its key stages, this is so the appropriate tools and techniques can be applied (Booker et al., 1997). In the approach presented here in Figure 5.11, the product development phases are activities generally defined in the automotive industry (Clark and Fujimoto, 1991). QFD Phase 1 is used to understand and quantify the importance of customer needs and requirements, and to support the definition of product and process requirements. The FMEA process is used to explore any potential failure modes, their likely Occurrence, Severity and Detectability. DFA/DFM techniques are used to minimize part count, facilitate ease of assembly and project component manufacturing and assembly costs, and are primarily aimed at cost reduction. 

A contractor helping with the study w ill definitely document such decisions. In fact, a contractor s most difficult task is extracting major decisions like this from tlie operating company s management. He will be diligent in documenting those that are handed to him on a silver platter. 

Each binary fork is attached to a branch of the preceding fork and is conditioned by the success or failure represented by that branch. Thus, evei7 fork, represents conditional probability. Each limb of the HRA event tree is described or labeled, in shorthand. Capital letters (A) represent I ailure lower case letters (a) represent success. The same convention applies to Greek letters, which represent non-human error events, such as equipment failures. The letters S and F are exceptions to this rule in that they represent system success and failure respectively, in practice, the limbs may be labeled with a short description of the error lo eliminate the need for a legend. The labeling format is unimportant the critical task in developing HRA event trees is the definition of the events themselves and their translation to the trees. 

Local ventilation is used to diminish or, preferably, to prevent exposure to contaminants (including heat). This includes protection of persons, products, or animals from hazardous and/or nuisance contaminants. This task is not specific for local ventilation and different definitions exist. One is the following ... 

Your initial tasks are to establish what the customer requires and what the expectations are, then convert this into a definitive specification or a design brief. 

PROBLEM DEFINITION. This is achieved through plant visits and discussions with risk analysts. In the usual application of THERP, the scenarios of interest are defined by the hardware orientated risk analyst, who would specify critical tasks (such as performing emergency actions) in scenarios such as major fires or gas releases. Thus, the analysis is usually driven by the needs of the hardware assessment to consider specific human errors in predefined, potentially high-risk scenarios. This is in contrast to the qualitative error prediction methodology described in Section 5.5, where all interactions by the operator with critical systems are considered from the point of view of their risk potential. 

PROBLEM DEFINITION, QUALITATIVE ERROR PREDICTION AND REPRESENTATION. The recommended problem definition and qualitative error prediction approach for use with SLIM has been described in Section 5.3.1 and 5.3.2. The fact that PIFs are explicitly assessed as part of this approach to qualitative error prediction means that a large proportion of the data requirements for SLIM are already available prior to quantification. SLIM usually quantifies tasks at whatever level calibration data are available, that is, it does not need to perform quantification by combining together task element probabilities from a data base. SLIM can therefore be used for the global quantification of tasks. Task elements quantified by SLIM may also be combined together using event trees similar to those used in THERP. 

Human Error Probability The probability that an error will occur during the performance of a particular job or task within a defined time period. Alternative definition The probability that the human operator will fail to provide the required system function within the required time. 

The first phase is a clear definition of the scope of work that is to be performed during the shutdown or maintenance outage. This definition must be more than a macro-level listing of the major tasks that are to be performed. Instead, each of these major or macro-level tasks must be fully defined. The purpose of this procedure is to provide an effective method of planning, material control, and follow-up of repetitive, non-repetitive, and capital shutdown work.
