本文研究了一个通用框架，用于估算由于无故障发现(NFF)现象而产生的维护成本。由于潜在的可使用设备被退回维修，这种间接费用特别难以量化。其他因素，如系统可用性的降低、高价值资产的可靠性降低以及后勤因素，都可能导致解决未知故障的成本。在这里，我们应用软系统方法来捕捉供应链中NFF的关键成本驱动因素，并建立一个框架来估计NFF的成本。我们使用多方法设计，包括在线调查、研讨会和半结构化访谈，以7个英国组织的12名关键参与者的信息为基础，研究与NFF相关的成本实践。这项研究确定了供应链(例如运输)、OEM(例如库存)和客户(例如损失的工时)的主要NFF成本驱动因素。基于主体的模型被用来评估这些成本动因对整体净收益成本的影响。分析显示了如何选择最合适的驱动因素来表示由于NFF事件及其对整个供应网络的影响而产生的累计成本。从学术角度来看，NFF成本估算的通用框架展示了如何同时使用定性和定量信息来实现维护目标。从实践的角度来看，通过将框架应用于一个组成部分，组织可以自由地分析该特定单位的净收益成本。
The article investigates a generic framework to estimate maintenance costs attributed to the No Fault Found (NFF) phenomenon. Such overhead costs are particularly difficult to quantify due to potentially serviceable equipment being returned for repair. Other factors, such as a reduction in the availability of the system, compromising reliability of high value assets, and logistical factors, can all contribute to the cost of resolving an unknown fault. Here we apply the soft systems methodology to capture the critical cost drivers of NFF across the supply chain and build a framework to estimate the cost of NFF. We use a multi-method design including an online survey, workshops and semi-structured interviews to study NFF related cost practices based on information from 12 key participants across 7 UK organisations. The study identifies the major NFF cost drivers across the supply chain (e.g. transportation), the OEM (e.g. inventory) and the customer (e.g. lost man hours). An agent based model is used to evaluate the impact of these cost drivers on the overall NFF cost. The analysis shows how the most appropriate drivers can be selected to represent the cumulative costs due to NFF events and their impacts across the supply network. From the academic perspective, the generic framework for NFF cost estimation demonstrates how qualitative and quantitative information can be used together to achieve maintenance objectives. From a practical perspective, by applying the framework on one component, an organisation has the liberty to analyse the cost of NFF for that particular unit only.
