Abstract: Background: Currently, nuclear emergency radiation monitoring system (NERMS) contains a wide range of equipments of different performance. The operational effectiveness of NERMS can only be judged by its technical performance or through operational exercises under assumed environmental condition. However, such judgement of NERMS’s operational effectiveness can neither reflect the influence of the real environmental conditions to the NERMS, nor verify the particular contribution of different models of the same category to the operational effectiveness. While the Availability Dependability Capability (ADC) model developed by the Weapon System Effectiveness Industry Advisory Committee (WSEIAC) is widely used for quantitative evaluations of weapon systems, it is suitable only for evaluation of individual equipment rather than the whole system. And the ADC model can not reflect the influence of operational environmental conditions. Purpose: This study aims to propose a novel method for the evaluation of NERMS which is adaptable to the real operational environment. Methods: The evaluation of NERMS is divided into two parts, one is the system design capability, and the other is its adaptability to the real operational environment. The integrated evaluation index system of NERMS is constructed. And the ADC model is improved by using ‘mark’ expression. Results: The result of the evaluation can quantitatively reflect not only the total operational effectiveness of NERMS’s multiple different equipment on the same task and the contribution of NERMS’s particular equipment to the total operational effectiveness, but also the operational effectiveness of NERMS’s different equipment on different tasks. Conclusion: The model proposed in this paper may serve as a reference for developing and improving NERMS.
