A context-aware framework for dynamic composition of process fragments in the internet of services

Abstract In the last decade, many approaches to automated service composition have been proposed. However, most of them do not fully exploit the opportunities offered by the Internet of Services (IoS). In this article, we focus on the dynamicity of the execution environment, that is, any change occurring at run-time that might affect the system, such as changes in service availability, service behavior, or characteristics of the execution context. We indicate that any IoS-based application strongly requires a composition framework that supports for the automation of all the phases of the composition life cycle, from requirements derivation, to synthesis, deployment and execution. Our solution to this ambitious problem is an AI planning-based composition framework that features abstract composition requirements and context-awareness. In the proposed approach most human-dependent tasks can be accomplished at design time and the few human intervention required at run time do not affect the system execution. To demonstrate our approach in action and evaluate it, we exploit the ASTRO-CAptEvo framework, simulating the operation of a fully automated IoS-based car logistics scenario in the Bremerhaven harbor

Knowledge for development : enhancing people's capabilities : a case-study of knowledge management and social entrepreneurship based on a Mexican community experience

This thesis presents a case-study based on the academic fields of Development Theory, Knowledge Management and Social Entrepreneurship that portrays the development history of a Mexican rural community (Huixcazdhá) that hosts a food processing company (San Miguel). The analysis uses concepts of human centered development and the Capability approach by Amartya Sen to describe the history of improvement of the wellbeing of people from the community thanks to the presence of the amaranth processing company. It also shows how despite the limitation in resources present in the environment where the business operates, San Miguel may be considered a knowledge creating company under the framework of Nonaka. Finally, it presents the personal history of the social entrepreneur in the establishment of a company with a strong social vision that completely integrates its business operations with the dynamics of the community. The research paradigm that provides light to the study is pragmatism; using case-study as research strategy and an inductive research approach, limitations intrinsic to these elements are discussed and tackled in the methodological design. The data collection stage included on-site observations in the company and community for a period of six months, carrying out thirty in-depth interviews to collect personal views of persons from the community who work in the company, and the analysis of different documents produced by the company, social entrepreneur, and external agents such as the media, government and other institutions. A Computer-Aided Qualitative Analysis Software (NVivo) was used to analyze all data obtained and to give shape to the conclusions drawn from the research.The main findings obtained in relationship to each of the fields of knowledge considered in the thesis are: In relation to Social Entrepreneurship, the ethical fiber as a personal characteristic of the entrepreneur is a major element that has not received enough attention; additionally the process to develop a social vision that captures a collective purpose with a transformative effect and a widespread reach to create and sustain social value is stressed. Regarding the field of Knowledge Management, the process of adapting the elements of a knowledge-creating firm in a rural environment with major limitations regarding the human and material resources is shown. In the field of Development Theory, a process view where primary assets of a community are turned into an expanded capability set that changes into a choice process to convert it into achieved functionings is introduced. Furthermore, the elements that connect the three fields based on pragmatism is introduced; particularly the spirits of bricolage, phronesis and distributed agency are analyzed and extracted from the empirical evidence as relevant elements in the construction of a successful experience of development
