1 Developing a coevolutionary account of innovation ecosystems
توسعه یک حساب همزمان از اکوسیستم های نوآوری-2021
Whilst research in innovation ecosystems has focused on the connectivity, interdependence, and coevolution of actors, technologies, and institutions, there has been a gap in the study of these relationships between actors, with little explanation given on how mutually interdependent parties adapt. In this paper, we draw further on the ecological metaphor to present a view of innovation ecosystems as complex adaptive systems, where patterns of change emerge from microlevel coevolutionary interactions between actors. Drawing on this view, we explore related implications for our understanding of ecosystem boundaries, coevolutionary rules of interaction, and how ecosystems are energized through innovation. Specifically, we contribute to the literature by developing a novel account of innovation ecosystems where actors are bound together through changing modes of coevolution. Drawing on this account, we explore key theoretical and practical implications for our understanding of ecosystem actors, rules of interaction, and the wider innovation ecosystem. We conclude that innovation both maintains and drives change within the innovation ecosystem, by altering the microlevel rules of interaction and coevolutionary relationships between actors.

2 A Machine Vision Based Automated Quality Control System for Product Dimensional Analysis
سیستم کنترل کیفیت خودکار مبتنی بر بینایی ماشین برای تجزیه و تحلیل ابعاد محصول-2021
Quality control (QC) in manufacturing processes is critical to ensuring consumers receive products with proper functionality and reliability. Faulty products can lead to additional costs for the manufacturer and damage trust in a brand. A growing trend in QC is the use of machine vision (MV) systems because of their noncontact inspection, high repeatability, and relatively low cost. This paper presents a robust MV system developed to perform comparative dimensional inspection on diversely shaped samples, including additive manufacturing products. The algorithm used performs dimensional inspection on a base product considered to have acceptable dimensions. The perimeter, area, rectangularity, and circularity of the base product are determined using blob analysis on a calibrated camera. These parameters are then used as the standard with which to judge additional products. Each product following is similarly inspected and compared to the base product parameters. A likeness score is calculated for each product, which provides a single value tracking all parameter differences. Finally, the likeness score is considered on whether it is within a threshold, and the product is considered to be acceptable or defective. The proposed MV system has achieved satisfactory results, as discussed in the results section, that would allow it to serve as a dependable and accurate QC inspection system in industrial settings.© 2021 The Authors.

3 Enhancing context specifications for dependable adaptive systems: A data mining approach
افزایش مشخصات زمینه برای سیستمهای انطباقی قابل اعتماد: رویکرد داده کاوی-2019
Context: Adaptive systems are expected to cater for various operational contexts by having multiple strategies in achieving their objectives and the logic for matching strategies to an actual context. The prediction of relevant contexts at design time is paramount for dependability. With the current trend on using data mining to support the requirements engineering process, this task of understanding context for adaptive system at design time can benefit from such techniques as well. Objective: The objective is to provide a method to refine the specification of contextual variables and their rela- tion to strategies for dependability. This refinement shall detect dependencies between such variables, priorities in monitoring them, and decide on their relevance in choosing the right strategy in a decision tree. Method: Our requirements-driven approach adopts the contextual goal modelling structure in addition to the operationalization values of sensed information to map contexts to the system’s behaviour. We propose a design time analysis process using a subset of data mining algorithms to extract a list of relevant contexts and their related variables, tasks, and/or goals. Results: We experimentally evaluated our proposal on a Body Sensor Network system (BSN), simulating 12 re- sources that could lead to a variability space of 4096 possible context conditions. Our approach was able to elicit subtle contexts that would significantly affect the service provided to assisted patients and relations between contexts, assisting the decision on their need, and priority in monitoring. Conclusion: The use of some data mining techniques can mitigate the lack of precise definition of contexts and their relation to system strategies for dependability. Our method is practical and supportive to traditional requirements specification methods, which typically require intense human intervention.

5 Forest landscapes as social-ecological systems and implications for management
مناظر جنگل به عنوان سیستم های اجتماعی-زیست محیطی و پیامدهای مدیریت-2018
Many of the most pressing threats to forests result from complex interactions between multiple stressors and require management on large spatial and temporal scales. For this reason, many ecosystem managers have begun to recognize the need to consider the broader context of decisions, and how outcomes of past, present and future decisions in one location may interact with outcomes of such decisions in other locations nearby. The landscape has been put forth as an appropriate unit for such holistic approaches to management. However, as there are differing definitions of landscapes, it can be difficult to develop frameworks for management. Moreover, many definitions do not fully account for the many ways social and ecological conditions and processes interact within landscapes. Building on emerging theoretical and empirical literature, I offer a perspective on temperate forest landscapes as social-ecological systems: nested sets of coevolving social and natural subsystems connected through feedbacks, time lags, and cross-scale interactions. This interdisciplinary framing emphasizes the bio geophysical and socio-cultural influences on landscapes and the need to consider these influences – and the interactions among them – in management. I discuss challenges to managing forest landscapes as social-ecolo gical systems that stem from mismatches in the temporal and spatial scales on which ecological and social systems typically function, as well as opportunities for policies, formal organizations, and governance networks.

6 Comparing HROs and RE in the light of safety management systems
مقایسه HROs و RE با توجه به سیستم های مدیریت ایمنی-2018
The High Reliability Organizations (HROs) and Resilience Engineering (RE) movements represent similar schools of thought, and may seem difficult to differentiate on clear grounds. This paper uses a generic taxonomy of safety management modes, developed during a field study conducted within the French Air Navigation Service Provider (ANSP), to facilitate their comparison. The field study was an opportunity to contrast the classical Safety Management System (SMS) regulatory approach with the HRO and RE frameworks. It also led to the development of a generic taxonomy of safety management modes, which is used for comparing the HRO and RE frameworks from a safety management perspective. While HRO and RE share a common theoretical inspiration (complex adaptive systems), a common philosophy of safety management, and reach similar conclusions in terms of “positive” safety management features, they can still be differentiated by their position in the grid. HROs are close to one of the four safety management modes described in the taxonomy, while resilience is a component of safety management that is present, at different levels, across all the four safety management modes.

7 FIoT: An agent-based framework for self-adaptive and self-organizing applications based on the Internet of Things
FIoT: یک چارچوب مبتنی بر عامل برای برنامه های خود تطبیقی و خود سازماندهی بر اساس اینترنت اشیاء -2017
Billions of resources, such as cars, clothes, household appliances and even food are be ing connected to the Internet forming the Internet of Things (IoT). Subsets of these re sources can work together to create new self-regulating IoT applications such as smart health, smart communities and smart homes. However, several challenging issues need to be addressed before this vision of applications based on IoT concepts becomes a reality. Be cause many IoT applications will be distributed over a large number of interacting devices, centralized control will not be possible and so open problems will need to be solved that relate to building locally operating self-organizing and self-adaptive systems. As an initial step in creating IoT applications with these features, this paper presents a Framework for IoT (FIoT). The approach is based on Multi-Agent Systems (MAS) and Machine Learning Techniques, such as neural networks and evolutionary algorithms. To illustrate the use of FIoT, the paper contains two different IoT applications: (i) Quantified Things and (ii) Smart traffic control. We show how flexible points of our framework are instantiated to generate these IoT application.

8 Hybrid modeling and empirical analysis of automobile supply chain network
مدل سازی هیبرید و تجزیه و تحلیل تجربی شبکه زنجیره تامین خودرو-2017
Based on the connection mechanism of nodes which automatically select upstream and downstream agents, a simulation model for dynamic evolutionary process of consumer driven automobile supply chain is established by integrating ABM and discrete modeling in the GIS-based map. Firstly, the rationality is proved by analyzing the consistency of sales and changes in various agent parameters between the simulation model and a real automobile supply chain. Second, through complex network theory, hierarchical structures of the model and relationships of networks at different levels are analyzed to calculate various characteristic parameters such as mean distance, mean clustering coefficients, and degree distributions. By doing so, it verifies that the model is a typical scale-free network and small-world network. Finally, the motion law of this model is analyzed from the perspective of complex self-adaptive systems. The chaotic state of the simulation system is verified, which suggests that this system has typical nonlinear characteristics. This model not only macroscopically illustrates the dynamic evolution of complex networks of automobile supply chain but also microcosmically reflects the business process of each agent. Moreover, the model construction and simulation of the system by means of combining CAS theory and complex networks supplies a novel method for supply chain analysis, as well as theory bases and experience for supply chain analysis of auto companies.

9 A Practical Approach to Modeling Complex Adaptive Flows in Psychology and Social Science
یک رویکرد عملی برای مدل سازی جریانهای تطبیقی پیچیده در روانشناسی و علوم اجتماعی-2017
Five moments in the formation and functioning of complex adaptive systems are: (1) emergent regularities and patterns in the flow of matter, energy, and/or information; (2) condensed schematic representations of these regularities enabling their identification; (3) reproductively interchangeable variants of these representations serving as templates for new instances of the pattern; (4) successful reproduction facilitated by the accuracy and reliability of the representations’ predictions of data flow regularities; and (5) informational feedback that adaptively modifies and reorganizes representations to incorporate new variations in the data flow, cycling back the first moment. These five moments are instantiated via stochastic models providing practical approaches to representing and managing complex adaptive psychological and social systems in education, health care, human resource management, etc. Local independence, unidimensionality, and statistical sufficiency criteria function as means of identifying, evaluating, and deploying conceptual and social forms of life acting as evolving agents in defined ecological niches. Bringing these agents into play systematically requires embodying them in technologies instrumental to making them readily recognizable and sharable across ecosystem niches. Modeling research and practice promoting sustainable and self-organizing ecosystems of this kind set the stage for redefining profit in terms of authentic wealth and value for life.

10 A conceptual framework for the analysis of the effect of institutions on biofuel supply chains
چارچوب مفهومی برای تجزیه و تحلیل اثر نهاد ها در زنجیره تامین سوخت زیستی-2017
The economic performance of biofuels supply chains depends on the interaction of technical character istics as technological pathways and logistics, and social structures as actor behavior, their interactions and institutions. Traditional approaches focus on the technical problems only. Little attention has been paid to the institutional analysis of biofuel supply chains. This paper aims to extend the analysis of the effect of institutions on the emergence of biofuel supply chains by developing a conceptual framework that combines elements of complex adaptive systems, (neo) institutional economics and socio technical systems theory. These elements were formalized into an agent-based model. The proposed method is illustrated by a case study on a biodiesel supply chain in Germany. It was found that the pat terns in production capacity result from investors basing their decisions on optimistic perceptions of the market development that increase with a favorable institutional framework. Conversely, patterns in bio diesel production cannot be completely explained by this mechanism. The proposed framework assisted the model conceptualization phase and allowed the incorporation of social structures into the agent based model. This approach could be developed further to provide insights on the effect of different future deployment strategies on bioenergy systems emergence and development.
