A series of human factors evaluations were undertaken to better understand the contributing factors to human error in the teletherapy environment. Teletherapy is a multidisciplinary methodology for treating cancerous tissue through selective exposure to an external beam of ionizing radiation. A...

Despite the increasing popularity of decision support systems (DSS), effectiveness of such systems remains unproven. Past research claiming usefulness of the DSS has relied largely on anecdotal or case data. The relatively few laboratory experiments report mixed results regarding the effects of...

A laboratory experiment was conducted to assess the influence of graphical and color-enhanced information presentation on decision quality, decision-making time and user perceptions of information systems attributes. The experimental design examined the main and interaction effects of report...

A key issue in designing a computer-based decision support system is how best to depict the data. Since most systems use either graphical or tabular displays, this experiment compares the latter two when used as decision aids for the production scheduling problem modeled by Holt, Modigliani,...

A logistics management game was modified to provide an information/decision system that would serve as a framework for experimentally investigating the impact of the mode of information presentation. Subjects played the game by making a series of weekly decisions during each of two playing...

This paper demonstrates concepts, collectively termed interpretive structural modeling, which can aid in the development of decision-support systems through: (1) creating a structure which helps identify the presence or absence of information necessary for decision-making; (2) providing a...
