“…Figure 2. SE DevOps (Mathieson et al, 2020) If we adopt the recommendation of Robison (2020) and recognise that agile is more about thinking and adaptation than following a prescribed process. No one has stated that defence acquisition "must" be conducted linearly.…”

This article re‐examines the model for large‐scale defence acquisition, aiming to establish a more adaptable framework that can effectively navigate the uncertainties of a dynamic and evolving operational environment. Drawing upon principles derived from Beer's Viable System Model (VSM), coupled with software engineering concepts from DevOps and innovation frameworks, the article proposes the development of a preliminary acquisition framework. The primary objective of this endeavour is to refine the framework, facilitating the creation of naval platforms that possess enhanced future‐proofing capabilities. Simultaneously, the aim is to minimize the time gap between significant acquisition decisions and achieving initial operating capability, all while upholding the fundamental requisites of the prevailing acquisition frameworks. Considering the extended operational lifespan of valuable assets, which can exceed two decades, there is a discernible risk that naval resources might become obsolete due to technological advancements driven by evolving adversarial threats. To counteract this potential scenario, it becomes imperative to regard naval acquisition as a continuous process, necessitating ongoing evolution and timely updates that align with the swiftly changing environmental conditions. This article asserts the significance of embracing a future‐proofing mindset. Such an approach holds the potential to curtail expenses associated with the swift and cost‐effective implementation of new capabilities as we advance into the future.

“…In 1965, with the proposal of works and concepts such as system engineering manual and fuzzy set, system engineering gradually became practical and standardized. In the 1960s, Chinese scholars such as Qian Xuesen and Xu Guozhi proposed important principles of engineering cybernetics and operations research, which provided design guidance for the distribution and array of sensor systems and established an important mathematical foundation for the stability of system operation [1][2][3]. For the stability evaluation of the system, American scholars S.Bocceletti and V.Latora studied whether the system structure can maintain the integrity after being destroyed, namely the robustness of the system.…”

A new design method of internet of things (IOT) sensor is proposed, various equipment in substation can be abstracted as a complex system composed of directly or indirectly connected equipment nodes, the widely arranged broadband current sensors are used to monitor the current characteristics of high-frequency partial discharge, leakage current and relative dielectric loss of each equipment nodes which are extracted to form a sensor array based on electric flow. System engineering theory is proposed to design the array sensor and is used to optimize layout and operation stability analysis. The designed model and interpretation structure model of IOT sensor system are constructed, based on the state equation or transfer function of the sensor array, the operation stability observation method of the sensor under the missing elements, slight disturbance and severe disturbance is proposed.
