This paper provides a context within which the role of human factors engineering (HFE) for Naval ship design may be understood. HFE is defined and its history as part of engineering design teams is traced. The role of HFE in ship systems design is defined, and the HFE Technology for Ships Program, managed by SEA 061R, is described. The rationale for inclusion of HFE in the design process is presented, the methodology whereby it is incorporated into the design process is detailed, methodology to assess the application of HFE is outlined, and the benefits that will accrue as a result of inclusion of HFE considerations in the design process are documented. The counterpoint to inclusion is illustrated through instances of design-induced human errors. A specific application of HFE in the acquisition process is illustrated through use of the Landing Craft, Air Cushion HFE program plan. The difficulties which may be encountered as the size of the target system expands are described. Potential roadblocks to the required incorporation of HFE are examined for their source and possible ameliorative steps.

A new adaptive computer control model in hot strip rolling has been developed. The main idea is to improve the accuracy of the force calculation and to balance the inter-stands load distribution by introducing a new adaptive systems based on the gradient technique and a stochastic approximation-type algorithm. The feasibility of the new method is demonstrated by off-line simulations using actual rolling data. The comparison of the new method with the conventional method shows that the accuracy of the force calculation can be remarkably improved, especially in down-stream stands where the reduction in draft is rather small, and that the inter-stands load distribution can be well balanced.

In this paper, education and training schemes needed to achieve a certain level of technological development is presented. The general strategy will be introduced first, then specific experiences of both professional educational organizations and industrial organizations will be given in some details. A discussion about the role and importance of education in information systems will be also presented.

This paper presents a description of recent computerized power generation plant automation and advanced man-machine interface systems. The automation software system is called COPOS (Computerized Optimum Plant Operation system), and the advanced man-machine interface software system is called PODIA (Plant Operation by Displayed Information and Automation). The authors describe, first of all, practical methods applied to the full automation of a fossil fired power plant by COPOS. For example, there is the fundamental philosophy of plant operation phases separation, sub-controlsystems separation, modes separation and WCD (Work control Drive). Also described is the COPOS software system, which features the problem oriented language (FILL IN BLANKS) called PLANT TABLES. Lastly, the authors describe the development of the displayed control panel, which makes effective use of many graphic color CRTs for advanced man-machine interface. The fundamental philosophy described in the paper is throughly useful and applicable to other process plants

Fast valving could cause second swing instability in a relatively weak system, though it is effective on first swing stability. This paper presents the proposed control methods for fast valving which are concerned with a practical way to control turbine power according to a fault severity and demonstrates their effectiveness by detailed digital simulations performed on a multimachine system.
