| Abstract Current Allocation of Function methods require significant levels of judgement and interpretation and there is an opportunity to develop an improved capability for Allocation of Function for the context of the Nuclear Reactor Plant. This paper presents the development and application of an Allocation of Function method that provides a flexible and configurable set of tools which can be selected in accordance to the design stage and project requirements. The Allocation of Function method has been designed to be used in an iterative manner throughout the different stages of design development and used to engage with different engineering teams. The method draws upon existing and well-established HF methods to investigate and capture human-system interactions associated with function delivery. It also focuses on cognitive tasks to ensure introduction of automation continues to provide support to the operator. Particular emphasis is placed on mapping and understanding the cognitive processes employed in function delivery to ensure that all functionality and information requirements are captured in future automation design. The method also informs assigning and selecting a Level of Automation to a function. The Allocation of Function method enables integration with Systems Engineering to trade HF requirements against the engineering requirements for provision of automation. |
