Audit in terms of Independence, Organizational Characteristics and Internal Relationships

The internal audit function's efficiency is greatly influenced by relationships, organisational characteristics, and internal audit independence. Independence is the capacity of the internal audit function to operate impartially and unbiasedly. By ensuring that the internal audit function has a clear reporting line to the board of directors or audit committee, as well as the resources and independence necessary to carry out its responsibilities, this is achieved. To evaluate the organization's risk management, control, and governance methods fairly, internal audit must be impartial. Organizational aspects include the internal audit function's structure, reporting lines, and resources. These characteristics are essential to guaranteeing the internal audit function can carry out its responsibilities and provide a fair assessment of the organization's risk management, control, and governance systems. The organisational characteristics should support and be consistent with the main objectives and strategy of the company. Internal relationships are interactions and connections between the internal audit function and other organisational entities. The internal audit function's capacity to carry out its responsibilities effectively and provide an unbiased assessment of the company's risk management, control, and governance systems depends on these relationships. These partnerships' essential components include coordination, collaboration, compliance, and efficient communication. To make sure that the organization's overall goals are realised, the internal audit function should closely collaborate with other organisational departments like finance, operations, and risk management. In order for the internal audit function to be able to give an objective and useful review of the organization's risk management, control, and governance procedures, it is crucial that internal audit independence, organisational characteristics, and internal relationships all be present. They all play a vital part in ensuring that the internal audit function can recognise risks, take steps to reduce them, and reassure the management and other stakeholders of the company.

Identification of Key Links in Electric Power Operation Based-Spatiotemporal Mixing Convolution Neural Network

As the scale of the power system continues to expand, the environment for power operations becomes more and more complex. Existing risk management and control methods for power operations can only set the same risk detection standard and conduct the risk detection for any scenario indiscriminately. Therefore, more reliable and accurate security control methods are urgently needed. In order to improve the accuracy and reliability of the operation risk management and control method, this paper proposes a method for identifying the key links in the whole process of electric power operation based on the spatiotemporal hybrid convolutional neural network. To provide early warning and control of targeted risks, first, the video stream is framed adaptively according to the pixel changes in the video stream. Then, the optimized MobileNet is used to extract the feature map of the video stream, which contains both time-series and static spatial scene information. The feature maps are combined and non-linearly mapped to realize the identification of dynamic operating scenes. Finally, training samples and test samples are produced by using the whole process image of a power company in Xinjiang as a case study, and the proposed algorithm is compared with the unimproved MobileNet. The experimental results demonstrated that the method proposed in this paper can accurately identify the type and start and end time of each operation link in the whole process of electric power operation, and has good real-time performance. The average accuracy of the algorithm can reach 87.8%, and the frame rate is 61 frames/s, which is of great significance for improving the reliability and accuracy of security control methods.

Power transformer overload risk evaluation based on temperature rise simulation and fuzzy analytic hierarchy process

The evaluation of transformer overload risk and operational safety is a systematic process. Selecting an appropriate method to accurately assess its overload operation risk is an urgent need for flexible control and safe and reliable operation of power systems. According to the thermal characteristics and state of the transformer, a method for evaluating the overload risk of transformers with improved accuracy based on temperature rise simulation calculation combined with the Fuzzy Analytic Hierarchy Process (FAHP) is proposed. The weights are calculated by fuzzy set theory and FAHP, and the overload risk of the transformer is finally determined. The method comprehensively considers the possible information conflict between the working condition data and the thermal characteristics of the structure itself, and the calculation results are accurate and the process is clear. The calculation results after substituting the actual data show that the method can accurately evaluate the overload risk and operational risk of the transformer. This method is beneficial to identify the relative importance of transformer overload risk factors, calculate transformer overload risk coefficients, and formulate transformer risk control methods.

Digital Twin-Based Risk Control during Prefabricated Building Hoisting Operations.

Prefabricated buildings have advantages when it comes to environmental protection. However, the dynamics and complexity of building hoisting operations bring significant safety risks. Existing research on hoisting safety risk lacks a real-time information interaction mechanism and lacks scientific control decision-making tools based on considering the correlation between safety risks. Digital twin (DT) has the advantage of real-time interaction. This paper presents a safety risk control framework for controlling prefabricated building hoisting operations based on DT. In the case of considering the correlation of the safety risk index of hoisting, the safety risk hierarchy model of hoisting is defined in the process of building the DT model. The authors have established a Bayesian network model into the process of the integrated analysis of the digital twin mechanism model and monitoring data to realize the visualization of the decision analysis process of hoisting safety risk control. The key degree of the indirect inducement variable to direct inducement variable was calculated according to probability. The key factor leading to the occurrence of risk was found. The effectiveness of the hoisting safety risk control method is verified by a large, prefabricated building project. This method provides decision tools for hoisting safety risk control, assists in formulating effective control schemes, and improves the efficiency of information integration and sharing.

Using a Duffing control approach to control the single risk factor in complex social-technical systems

An approach based on forced Duffing Equation with cubic term is proposed to solve the single risk factor control problem in complex social-technical systems from the micro perspective. The single risk control problem is transformed into a system vibration control problem. Firstly, the relationships among Duffing Equation, system state sudden change and single risk factor control are analyzed. System control point crosses the bifurcation set is an important condition for the system state sudden change, the Duffing Equation can be used to establish the vibration equation of the complex social-technical system, and the risk control method of the complex social-technical system can be deduced based on the vibration equation. Secondly, the interference of the external environment in Duffing Equation is defined as the energy change of risk pulse. Next, we establish the system risk control equation and derive its bifurcation response equation with stable solutions. Under three safety protection measures conditions, including strengthening internal damping of system, reducing external excitation influence, strengthening internal damping of the system while reducing external excitation influence, three system risk control strengthening equations are established and their corresponding bifurcation response equations with stable solutions are derived, respectively. Finally, a real-world case study is conducted.

Safety Analysis and Ship Recycling Yard Evaluation of Hong Kong International Convention for The Safe and Environmentally Sound Recycling of Ships

The condition of the Indonesian fleet, which is in its old age, allows ships to be recycled as the best solution. However, conditions in the field, there are still many ship recycling processes that do not obey the rules, especially on the effect of workers and also the effect on the environment. In Indonesia, there are still many ship recycling yards that do not pay attention to the effects on workers and the effects on the environment and most of them are still traditional shipyards. Therefore, one of the best solutions is to renew existing regulations, namely the Hong Kong International Convention for The Safe and Environmentally Sound Recycling of Ships. When the implementation of this convention, the ship recycling shipyard must adjust to the convention. This study focused on the analysis of the assessment of the condition of Occupational Health and Safety (OHS). To evaluate the condition of the shipyard, the Gap Analysis method is by comparing the ideal conditions with the existing conditions at that time. The analysis is carried out using the Hazard Identification Risk Assessment Risk Control (HIRARC) method. This method is carried out by identifying hazards, which then provides a risk assessment and recommends how to control it. Based on result, risk matrix were obtained, which contained the assessment categories of Low, Moderate, High and Extreme. The results of this study through the gap analysis method, the average value is 2.1, which means that this value is still very low because the value of 0 - 2 is categorized as still many sub-clause indicators that do not exist or are not handled. Furthermore, in research using the HIRARC method, 60 risk matrices were obtained, which contained the assessment categories of Low, Moderate, High and Extreme.
