“…The reliability allocation [19,20] is to assign the target reliability of a task to the appropriate subsystems, components, and nodes of the system to determine the reliability of each component. Referring to the reliability allocation algorithm in [21], we assign the target reliability of the task to the two stages and use them as the target reliability of each stage (Algorithm 1, TRETA-Cluster, Lines 5–6; RA is the reliability distribution function).…”

Task assignment is a crucial problem in wireless sensor networks (WSNs) that may affect the completion quality of sensing tasks. From the perspective of global optimization, a transmission-oriented reliable and energy-efficient task allocation (TRETA) is proposed, which is based on a comprehensive multi-level view of the network and an evaluation model for transmission in WSNs. To deliver better fault tolerance, TRETA dynamically adjusts in event-driven mode. Aiming to solve the reliable and efficient distributed task allocation problem in WSNs, two distributed task assignments for WSNs based on TRETA are proposed. In the former, the sink assigns reliability to all cluster heads according to the reliability requirements, so the cluster head performs local task allocation according to the assigned phase target reliability constraints. Simulation results show the reduction of the communication cost and latency of task allocation compared to centralized task assignments. Like the latter, the global view is obtained by fetching local views from multiple sink nodes, as well as multiple sinks having a consistent comprehensive view for global optimization. The way to respond to local task allocation requirements without the need to communicate with remote nodes overcomes the disadvantages of centralized task allocation in large-scale sensor networks with significant communication overheads and considerable delay, and has better scalability.

“…It can be concluded from equation 2that we should allocate a higher reliability goal for the elements with lower complexity and higher importance. 17 In contrast to the AGREE method, the ARINC allocation method 10 took the quantified failure rates of subsystems as the allocation factor to distinguish the different reliability requirements as given in equation (3). The failure rate l i of subsystem i could be obtained from huge statistics data.…”

“…The Boyd 18 made use of the weighted sum of the equal method and the ARINC method to fulfill their allocation. Meanwhile, aiming at the networked system, Li et al 17 analyzed the shortage of the proposed importance and complexity in AGREE to develop an improved AGREE method for multiple missions where the allocation adjustment procedure is provided for further optimization. Furthermore, in order to obtain more reasonable allocation results, the more influence factors are also integrated in these methods.…”

In recent years, reliability optimization allocation has drawn a broad spectrum of attentions, especially for complex systems consisting of a large number of subsystems and components. Hydraulic system, deemed as a complex system, plays a great role in reliability increment of the CNC honing machine. In order to realize the CNC honing machine tool’s balanced operating performance, the crucial hydraulic system is designed to obtain the optimal and well-balanced allocation solution under the constrains of cost and reliability. Meanwhile, the quantified operating factor that influences the allocation solution is rarely considered adequately when operating samples are insufficient. So, if hydraulic systems are used in a new required longer operating mission duration or a new severer operating environment, the dissatisfied reliability could not be better reallocated to adapt to this environment with appropriate methods. Aimed at overcoming the abovementioned shortcomings and optimizing the dissatisfied reliability for existing hydraulic systems, this paper proposes a reliability optimization allocation method considering operating the condition information. From the standpoint of the complex system, this method firstly builds a three-level reliability optimization allocation model based on the analytic target cascading for the specific hydraulic system of CNC honing machine 2MK2263 × 200. It transforms the complex reliability allocation problem to a set of smaller and coordinated optimization sub-problems. Secondly, through studying the operating reliability problems of small samples in the new operating scene, the reliability prediction results based on the operating condition information are applied to build the initial reliability targets, which are regarded as the initial constrains for the optimization. With the help of analytic target cascading model and initial target reliability, the optimal reliability for the complex hydraulic system would be obtained. It is also shown to provide an innovative route for the reliability redesign of the related complex systems for this new required operating scene.

“…Air Wisconsin and Jet Age Airline claimed that nearly 50% and 30% of AOG (Aircraft On Ground) incidents were related to avionics (particularly to interconnected equipments). Maintenance-related failures have been associated with up to 15% of major aircraft accidents [19]. Despite this seemingly small percentage, but Vassilis Tsagkas [25] found that maintenance related failures are the second leading cause of fatal accidents in aviation exceeded only by pilot error.…”

“…Avionics System can be divided into three system levels, system, subsystem and component, which are involved in this paper. The three system levels can be defined as follows [19]: (1) a system is a combination of subsystems that complete a task together, (2) a subsystem consists of components, which can perform a specific function of the system, and (3) a component is an operating part of the subsystem. Taken a domestic avionics as an example(see Fig.1),the avionics system can be divided into seven subsystems according to their functions and operational characteristics, which is made up of subsystems including flight control subsystem, engine control subsystem, cockpit control-display subsystem, energy control subsystem, fuel and LG(landing gear) control subsystem, cabin control subsystem and airborne network subsystem.…”

In that sense, the importance of maintenance activity has increased due to its key role on improving system availability, performance efficiency, safety and reliability, etc. Thus in order to improve avionics considerations in general, maintenance managers (MM) should take decisions about the maintenance strategies to be implemented as well as the necessary resources to satisfy avionics system performances and requirements. Proper maintenance schedule is required to improve avionics systems reliability and safety. A decision approach to maintenance strategy remains a longstanding challenge in avionics system. With regard to fault diagnosis and equipment maintenance of avionics system, in which the equipment fault information are complex and uncertainty, a multi criteria of decision making method for avionics system based on cognitive uncertainty information processing is proposed to be used in the maintenance strategy decision. Firstly, vague set with three-parameters is introduced to make up for the shortage of the original vague set in expressing fuzzy information, a linguistic variables describing the qualitative indexes into three parameter vague of interval number is proposed. At the same time, due to risk psychological factors of maintenance policymakers that cause cognitive uncertainty are introduced into the maintenance decision process, and a prospect value function of three parameters vague interval value is defined based on prospect theory and the formula for measuring the distance between vague interval value, and a non-linear model of equipment maintenance policies can be established. The implementing process of maintenance policy decision for avionics system based on cognitive uncertainty information processing is given in this paper, and a ranking of the maintenance alternatives is determined. Finally, A specific example of decision of maintenance strategies in avionics system with the application of the proposed method isSatisfactory performance of an aircraft depends up on the continued reliability, security, features enhancements of avionics system. Reliability is proportional to amount of maintenance received and knowledge of men who performed such maintenance [13,17]. Now, an avionics system may comprise a large number of components, and efficient maintenance strategy is required to improve the reliability of relevant functions and to reduce high maintenance cost. For a long time, both home and abroad have to take preventive tests and...
