System Performance Requirements

Eckert [125] provides some basic guidelines to good packing selection for various system performance requirements. Kunesh [126] illustrates the often-determined pressure drop advantage of random packed towers over the usual valve tray. See Figure 9-19 [126],...

This technique is useful for analyzing workload, allocating tasks, and determining human and system performance requirements. When the resource requirements for each lower-level task are mapped to the timeline, the result is a dynamic task-demand profile. 

In the choice of a proof test interval, considerations should be given to the demand rate for Demand Mode systems, the failure rate of each component being tested, and the overall system performance requirements. 

The enterprise defines the performance requirements for each function of the system. Performance requirements describe how well functional requirements must be performed to satisfy the MOEs. These praformance... 

Performance requirements are divided into allocable sets and are directly allocated to functions. Requirements that are not directly allocable, such as range, should be translated into derived performance requirements, such as fuel capacity, engine efficiency, and vehicle resistance, through appropriate engineering techniques and analyses. The enterprise documents the allocation of system performance requirements to functions to provide traceability and to facilitate later changes. 

Loss of vehicle system As defined in NHB 5300.41(lD-2), Loss of the capa-biUty to provide the level of system performance required for normal or emergency operations (NSTS 22254). 

Synthesis is the process by which concepts are developed to accomphsh the functional requirements of a system. Performance requirements and constraints, as defined by the functional analysis, are applied to... 

The system engineering process does not actually design the system. The system engineering process produces the documentation necessary to define, design, develop, and test the system. The technical integrity provided by this documentation ensures that the design requirements for the system elements reflect the functional performance requirements, that all functional performance requirements are satisfied by the combined system elements, and that such requirements are optimized with respect to system performance requirements and constraints. 

For finer feature sizes, the interconnection delay plays a more important role, due to more complex designs fitting into one chip and the higher system performance required. Redundant operator allocation becomes a feasible solution due to the smaller area of operators. Our predictions show the interconnection delays will become dominant when submicron fabrication process are used. 

Research and development (R D) has a vital role in providing the methods, data, and sound judgments needed for developing and evaluating new technology. Adequate and exhaustive testing is essential, be it hardware, software, or firmware, for proving any new innovation or product, to establish or refute the safety claims, and to underpin system performance requirements. 

Preliminary investigations prior to the development of the AutoNom computer system had concluded that the hierarchical principle underlying the approach to a chemical name construction (parent, substituent, substituent-on-substituent, etc.) should be followed as faithfully as possible while designing the appropriate data format for the name generation analysis. It was decided to implement the format based on an ordered binary tree concept as fulfilling the majority of both nomenclature and system-performance requirements. The data structure maintained in the memory of the computer during nomenclature-guided analysis of the input compound will be hereafter referred to as the name tree .
