Total System Intervention

In this paper, total system intervention for system failure (TSI for SF) is proposed for preventing further occurrences of system failures. TSI is a critical system practice for managing complex and differing viewpoints. First, the authors introduce meta-methodology called “system of system failures” (SOSF) as a common language among various stakeholders to improve their understanding of system failures. The actual application scenario is proposed: “TSI for SF.” The SOSF and related methodologies are used in the course of the subsequent discussion and debate to agree on who is responsible for the failure and identify the preventative measures to be applied. An application example in information and communication technologies engineering demonstrates that using the proposed “TSI for SF” helps prevent future system failures by learning from previous system failures. Three actions are identified for preventing further system failures: closing the gap between the stakeholders, introducing absolute goals, and enlarging system boundary.

Charging Strategy

The coordinated scheduling of plug-in electric vehicle (PEV) charging should be constructed in distributed architecture due to the growing population of PEVs. Since the information and communication technology makes the adversary more permeable, the distributed PEV charging coordination is vulnerable to cyber-attack which may degrade the performance of scheduling and even cause the failure of scheduler task. Considering the tradeoff between system-wide economic efficiency, distribution level limitations and PEV battery degration, this paper investigates the resilient distributed coordination of PEV charging to resist cyber-attack, where the steps of detection, isolation, updating and recovery are designed synthetically. Under the proposed scheduling scheme, the misbehaving PEVs suffering from cyber-attack are gradually marginalized and finally isolated, and the remaining well-behaving PEVs obtain their own optimal charging strategy to minimize the total system cost in distributed architecture. The simulation results verify the effectiveness of theoretical method.

The use of information and communication technologies continue to grow each year. This is in line with the increasing demands for the distribution of information quickly and accurately. To keep the system of information and communication technologies into one quality enhancer in a College, then required the existence of a system of governance audit of information technology communications so that all factors are interconnected with the use of information technology can run as expected and all service information and communication technology can continue to be improved by the application of information technology is right on target. The existence of a good system of governance is the answer for the use of information and communication technology systems that are reliable. The role of the audit of the governance system of information and communication technologies as a means of decision makers is needed by a college to ensure that the application of information technology is in compliance with the planning. The COBIT frameworks has a coverage of control purposes which consists of 4 domains (ITGI, 2007), that is Planning and Organization (PO), Acquisition and Implementation (AI), Delivery and Support (DS), and Monitor and Evaluate (ME). In addition to this COBIT framework also has a Maturity Model that is used to find out the position of the maturity of the current governance and continuously strive to improve the level up to the highest level in order for all aspects of the management towards information technology can be done more effectively. Then the results of this research is the description of the analysis of the level of maturity of the implementation of the corporate governance of information and communication technology systems using COBIT framework 4.1 on Library STMIK Palangkaraya.
