“…Therefore, which of these dimensions we need to consider will be identified based on the characteristics of SG. More specifically, whether we need to consider only the four IQ dimensions identified in [13], a subset of them, or we need to extend them by considering other dimensions (e.g., believability, trustworthiness, etc. ).…”

Nowadays, most developed countries need to optimize their electricity production and consumption, which has led to the development of the Smart Grid (SG) concept. SG has a main objective of optimizing the generation, consumption, and management of electricity via information and communication technology. However, the vast amounts of information generated and processed in SG environments raise the issue of Information Quality (IQ). Accordingly, IQ has become an increasingly prominent issue in SG, since IQ can directly affect the services quality, reliability, and availability of an electric power supply. Despite this, the current IQ related issues in SG are still addressed in an ad-hoc manner. Without considering IQ requirements during the design of SG, it will be vulnerable to faults arising from depending on low-quality information, which may influence the dependability, reliability and efficient performance of SG. In this track of research, we aim at tackling this problem by developing a model-based approach for modeling and analyzing IQ requirements for SG.

“…have been proposed (e.g., [9]- [12]). We highlighted the limitations of these models for analyzing IQ for SoS in our previous work [13], and we proposed a conceptual model for analyzing IQ for SoS in terms of four IQ dimensions 2 (e.g., accuracy, completeness, timeliness, and consistency) that tackles the limitations of existing IQ models.…”

“…Information quality is inherently a hierarchical multidimensional concept [21], [31], [36], [37], [38] with inherent limitations when applied to a specific application domain [31]. Though the dimensions of information quality changes dynamically [33], several typical dimension classifications of information quality in the literature are shown in Table 1.…”

Supply Chain Logistics Information Quality Evaluation From Just-in-Time Perspective

et al. 2020

In this paper, we seek to evaluate supply chain logistics information quality (SCLIQ) from the Just-In-Time (JIT) perspective. First, based on the analysis of SCLIQ, it is proposed that the SCLIQ evaluation should be combined with JIT philosophy. Second, based on SPC and information entropy method, an evaluation method of SCLIQ is presented. The statistical process control method (SPC) is adopted to evaluate the information quality of quantity and time respectively, the information entropy method is employed to determine their weight and the comprehensive evaluation results, and these results are analyzed according to SPC. Finally, a numerical example is used to demonstrate the feasibility of the proposed method. The major contribution of this paper is the combination of SQLIQ and JIT philosophy, while an objective and comprehensive evaluation method of SCLIQ from the JIT perspective is developed. The results are useful for evaluating SCLIQ and determining the best direction of improvement activities.

A Cyber-Physical System-of-Systems (CPSoS) can be defined as a System-of-Systems (SoS), composed of a number of operable and autonomous Constituent Systems (CSs) that are themselves Cyber-Physical Systems (CPSs). A main challenge in integrating CPSoS to function as a single integrated system is the autonomy of its components, which may result in conflicts due to the lack of coordination among its CPSs. In this paper, we advocate that in order to facilitate the integration of CPSs within the overall context of their CPSoS, we may need to adjust their level of autonomy in a way that enables them to coordinate their activities to avoid any conflict among one another. Reducing such conflicts surely contributes to the dependability of the CPSoS. In particular, we propose a novel modelbased approach for modeling and analyzing the autonomy levels of CPSs based on their awareness concerning their operational environment as well as their capability to react in a timely and safe manner while performing their activity. The model is further described in a UML profile and applied to represent activities for autonomous driving scenarios. Using a driving simulator, we implement such models on a target vehicle and we show the resulting safety improvement, especially in terms of reduced collisions.
