Selection by Simulation: A Work Sample Approach to the Selection of ProcessAlgebras

摘要

The application of the work sample approach to the development of a selectioninstrument for process operators is investigated. Two approaches to the development of a selection instrument, sign versus sample, are examined and underlying assumptions of either approach are discussed. The literature on the work sample approach is reviewed and important concepts such as reliability and validity with regard to selection tests are discussed. The design cycle as used in the engineering sciences is introduced as a framework for the development of the work sample. Emphasis is on the iterative and cyclic character of the design process. Key elements of the process operator's control task are identified, construction of several provisional versions of the work sample is described and results of pilot experiments for 'tuning' the instrument are presented. The design of four validity studies in the 'final' version of the work sample is outlined. Results of these validation experiments are described. An evaluation of the most important findings is provided and the usefulness of the work sample approach for selection of process operators is discussed.
