Tremendous money is wasted due to the lack of attention to the water gauge and flue plate stiffeners, and their impact on the insulation and lagging design. The design and installation of an insulation and lagging system will depend heavily upon the flue or duct stiffener arrangement. The stiffener arrangement is determined by many factors including the water gauge of the flue or duct plate design. The stiffener pattern and size is the first thing you consider when designing an insulation and lagging system. Therefore, it is imperative to understand how the size, shape and pattern of the external stiffeners are developed. The stiffener sizing of yesterday was based on a much lower water gauge pressure and allowed the insulation to be placed between the stiffeners without having to cut-to-fit. The stiffeners being designed today are quite large and much farther apart. This is due in part to the water gauge number being used in the design calculations and because they have not considered the required insulation thickness and application. A well designed and installed insulation and lagging system will save money and energy at a rate that is essential for an efficient plant operation. This is especially true when adding a selective catalytic reduction system (SCR) or a selective non catalytic reduction system (SNCR) to the back end of a steam-generating unit. The insulation and lagging system is critical for these air pollution systems to operate correctly.

An overview is provided of the manner in which hydrodynamic and hullform-related design considerations were addressed in the development of the BAE SYSTEMS team’s design proposal for the UK Future Aircraft Carrier (CVF). It also outlines how broader design considerations such as aviation, survivability and supportability requirements influenced these aspects of the design. A summary is also provided of some of the more detailed requirements development, option assessment and performance evaluation work that has been undertaken. The aircraft carrier designs discussed in this paper correspond to the BAE SYSTEMS team’s final design submission as it stood in January 2003, at the time it was discontinued by the UK Ministry of Defence, in favour of the rival Thales / BMT team design that has since been developed into the UK Royal Navy’s new ‘Queen Elizabeth’ class aircraft carrier. This final BAE SYSTEMS design submission consisted of two distinct design variants - one configured to operate a CTOL-based air group, the other configured to accommodate a STOVL air group. Both variants were based on a common ‘core’ ship design. The discussion presented in this paper is applicable to both variants.

Design Considerations

Job and organization design are increasingly important variables when one takes into consideration the two key objectives sought by most organizations: organizational effectiveness (productivity) and member welfare (job satisfaction). Job design is most relevant at the microergonomic level where the focus is upon human-machine and work station factors. Organization design is, of course, more concerned with the macroergonomic aspects of systems and their structures. The panel will address both of these areas of interest, and will present different perspectives and new directions in both job and organization design. Dr. Griffin, in his presentation entitled “Individual, Work-Related, and Social System Factors in Job Design/Redesign”, will discuss how a considerable amount of research over the last several years has demonstrated the complexities involved in how individuals develop their perceptions of their jobs and how they subsequently respond to their jobs. One category of variables which affects perceptions and reactions is the individual. Elements such as experiences, aspirations, and abilities all come into play. The work-related factors which have received the most attention include the objective job itself and the physical setting in which it is performed. Finally, social system variables such as the immediate work group, organizational culture, and occupational status also affect how people perceive and respond to their jobs. This portion of the discussion will summarize each of these perspectives, suggest avenues for potential integration, and identify major implications for organizations. Dr. Hendrick will address the topic of systems design from the macroergonomic perspective. Dr. Keller will present design considerations from both micro- and macro-points of view. Dr. Laughery discuss design considerations as they relate to safety and accidents. Each participant will also address other design issues. A discussion of some theoretical foundations of job and organization design will also be presented and current applications will be discussed. A model of job design will be put forth which includes current knowledge and components of managerial approaches to job design/redesign. The redesign of core job characteristic dimensions approach will also be discussed, as will the importance of need strength in job design. And finally, application of a sociotechnical systems approach to organization design is advocated so that organizations are designed to operate in the most effective possible way to achieve increased organizational effectiveness and quality of work life through an integration and joint optimization of psychosocial, cultural, and technological factors with human-machine performance interface factors.

In common high-end precision systems, thermal effects, in general, play a very important role with respect to the final performance of the system. Mainly driven by miniaturization, performance and reliability enhancement, the requirements of these systems have enormously increased over the last few decades. To stimulate exchange of knowledge and cooperation in the precision engineering community a special interest group was initiated by the Euspen. During a meeting in 2006 it turned out that thermal effects occur in many different applications and in all forms. The complexity of the thermal effects and the high impact on the performance of systems motivated the group to organize a conference in 2007. All kinds of applications were mentioned, starting from traditional machine tools up to next-generation lithography tools and analysis tools. The huge diversity of the thermal issues in all kinds of market segments was also very clearly discussed.
