“…So every state of the system must be identified [9]. In order to reduce the cost of identification, IMA platform and IMA application should be independent [10]. From the perspective of application, if there is no change of the platform before and after reconfiguration, we only need to confirm the dependability of each configuration of the platform.…”

Today, more and more digital electronic devices are used to improve aircraft's operational performance. It presents a problem that increasing number of avionics components leads to more system failure and more unscheduled maintenance. For this problem we research an enhanced reconfiguration method about the future Integrated Modular Avionics (IMA). And present a simulation that indicated the method can resume the system's original state after a failure occurs, enable the plane fly with fault, avoid unscheduled maintenance, and then save the operation expense of airline.

“…Component Fault Trees and Markov chains are used to estimate failure probabilities. Similarly, the integrated modular avionics paradigm shares the goal of replacing software units via standardized generic hardware modules . Their goal is not to use heterogeneous redundancies in highly networked scenarios, but exploit replaceable processing units in reconfiguration.…”

Design strategies that benefit from the reuse of system components can reduce costs while maintaining or increasing dependability-we use the term dependability to tie together reliability and availability. D3H2 (aDaptive Dependable Design for systems with Homogeneous and Heterogeneous redundancies) is a methodology that supports the design of complex systems with a focus on reconfiguration and component reuse. D3H2 systematizes the identification of heterogeneous redundancies and optimizes the design of fault detection and reconfiguration mechanisms, by enabling the analysis of design alternatives with respect to dependability and cost. In this paper, we extend D3H2 for application to repairable systems. The method is extended with analysis capabilities allowing dependability assessment of complex reconfigurable systems. Analysed scenarios include time-dependencies between failure events and the corresponding reconfiguration actions. We demonstrate how D3H2 can support decisions about fault detection and reconfiguration that seek to improve dependability while reducing costs via application to a realistic railway case study.A high-level function consists of a set of Main Functions (MF), for example, train operating properly = {traction system OK, signalling system OK, braking system OK, air conditioning control OK, . . . }. Main functions are performed in possibly different Physical Locations (PLs), for example, a single air conditioning control implementation may span a whole train car, or each car compartment in a train car may have its own air conditioning control. A main function consists of a set of subfunctions (SF), for example, input, control and output subfunctions. A subfunction may have multiple implementations (#) to carry out the subfunction, and these are ordered with respect to their priority.

“…The main goal to be achieved by the reconfiguration is to improve the operational safety of the system also in case of faults while preserving the required safety properties. A reconfiguration can be considered in different scenarios such as [8]: (a) granularity level-reconfiguration is either performed at execution node or at partition level. For node level reconfiguration, a spare execution node is allocated to all SW applications running on the faulty computing node.…”

This paper proposes a new safety framework and platform for the functions of future electrical/electronic (E/ E) systems. The framework aims to cope with the increasing complexity of the E/E systems, and to enhance their flexibility, but retain the safety properties and keep low engineering costs. A domain-specific meta-model is used to specify relevant aspects of the system such as component interface requirements and function descriptions. The meta-model is used in a tool that generates data structures, which are then used to configure the faultmanagement layer of the run-time environment. The faultmanagement layer preserves the safety properties of the system at run-time, by facilitating error detection and faulthandling mechanisms, and supporting controlled adaptation. By reusing already developed safety measures for different systems and functions, future development costs for non-functional qualities can be saved.
