ABSTRACT Demand for computed tomography (CT) and CT waiting lists are growing, a problem exacerbated by the postponement of scheduled services during the Covid-19 pandemic. In this case study operational research (OR) methods were used to investigate resource utilisation and CT waiting list growth. Stakeholder involvement was facilitated using system dynamics (SD) for problem conceptualisation and Soft Systems Methodology (SSM) to identify service issues, data requirements, and scenarios for testing. Discrete event simulation (DES) was used to generate metrics pertaining to daily staff work load, process performance (delays) and waiting list evolution, for the current and alternative scenarios. Lessons learnt from the perspective of a clinical modeller are discussed throughout. DES model outputs illustrated the high daily variation in resource utilisation and process delays for the current service where inpatients and outpatients share a single CT scanner. Inpatient examinations were found to consume on average 23% more staff time than outpatient. For non-contrast CT scans, outpatients consumed 63% less time than inpatients. Simulation results for an outpatient-only service demonstrated higher CT and healthcare assistant utilisation, with low variation and process delays. This work recommends the separation of inpatient and outpatient CT services to address the problem of growing CT waiting lists.

ABSTRACT The research investigated whether Perceptual Control Theory (PCT) can be used to model the decisions of small groups utilizing data from the Beer Game. The PCT model was tested on public and MSc data operating the Beer Game. Investigations of closed-loop behaviour determined the perceived disturbance was the controlled variable. A set of PCT Simulink models was built and their parameters adjusted to give responses comparable to the human Beer Game based on the groups’ orders alone. A few groups appear to have additionally used the backlog as input. PCT, incorporating the principle of closed loop control, does represent the human management of the Beer Game, giving an overall correlation coefficient of 0.70-0.74 obtained between the orders from a PCT model and those used in the Beer Game from 14 groups of participants and supported by minimum weighted integrals IAE and ITAE and Kolmogorov-Smirnov 2 sample tests.
