The accident at Three Mile Island (TMI) has underscored the need for human factors review and analysis of Nuclear Control Rooms. Virtually every study of the TMI debacle has come to the conclusion that one of the major contributors of the accident was poor human engineering. In recognition of this fact, the nuclear industry, through its research institutes, has initiated a series of research programs designed to provide individual utilities with guidelines on how to apply human factors principles and criteria to improve the safety and performance of their nuclear facilities. The present paper reports on one of the major studies being undertaken by the Electric Power Research Institute (EPRI) in the area. The objective of this research project is to identify and prioritize the existing Human Engineering Discrepancies (HEDs) in nuclear control rooms and to develop retrofits for correcting these HEDs that can be implemented during normal plant operation or during planned outages. Data was collected during one week visits to five power plants. Structured interviews, checklists, task analyses, surveys (noise, light, etc.) and procedural walk-throughs/talk-throughs were employed to assess the design and layout of the control rooms. In depth analyses of these data led to the identification of numerous HEDs. A prioritization scheme was developed to determine the relative seriousness of these HEDs and to rank alternative retrofit solutions in terms of cost and feasibility. The results revealed fairly wide variance in the extent to which control rooms violate human factors principles. The most frequent areas in which violations were found are labeling, alarm/display systems, functional grouping, design conventions, and anthropometric limits. Numerous HEDs along with alternative retrofits are shown and discussed. Emphasis is given to cost and engineering consideration in selecting appropriate backfits.

Using Data

We investigate two determinants of two choices in the control system of divisionalized firms, namely decentralization and use of performance measures. The two determinants are those identified in the literature as important to control system design: (1) information asymmetries between corporate and divisional managers and (2) division interdependencies. We treat decentralization and performance measurement choices as endogenous variables and examine the interrelation among these choices using a simultaneous equation model. Using data from 78 divisions, our results indicate that decentralization is positively related to the level of information asymmetries and negatively to intrafirm interdependencies, while the use of performance measures is affected by the level of interdependencies among divisions within the firm, but not by information asymmetries. We find some evidence that decentralization choice and use of performance measures are complementary.

Human Factors Analysis

With the advent of voting machines and computers, the voting process has evolved into a complex man-machine system. However, to date no comprehensive human factors analysis of the voting process has been conducted. A systems analysis of the voting process yielded four major functions which impact critically on voter behavior and performance: (a) Design of voting instructions (b) Display of crucial voting information (c) Human engineering of voting equipment and procedures (d) Distribution of voting machines and personnel across and within voting districts. Some critical aspects of each area are discussed, and some additional points of interest to human factors specialists interested in researching this area are mentioned.
