This chapter has introduced a novel, industry-proven BPMS employing a goal-oriented approach to modelling and executing agile business processes. We have demonstrated that this is an inherently flexible approach, allowing processes to be designed and executed
Conference Paper
Full-text available
This paper discusses an approach to seamless hybrid connectivity bridging infrastructure-centric and ad-hoc networks to autonomically maximize the potential for sustained connectivity for terminal device users and their services. The architecture and functional attributes of a hybrid connectivity manager are described, and illustrated through deplo...
Conference Paper
Full-text available
In this paper we shortly describe the Living Systems® Autonomic Business Process Management (LS/ABPM) software product. LS/ABPM is an integrated environment, based on J2EE, Eclipse and Agent Technology, to support agile Business Process Management through goal-oriented process modeling, autonomic business process navigation and a multi-layer extens...
Chapter
Full-text available
This paper presents an approach to manipulating available hybrid connectivity to autonomically maximise the potential for sustained connectivity in the event of path disruptions. The approach is documented in terms of the features, architecture and deployment modes of an autonomic communications module, termed RASCAL. This module employs software-a...

This chapter presents the Living Systems Autonomic Service Access Management Suite, LS/ASAM, a comprehensive middleware solution enabling adaptive connectivity management of nomadic end hosts across heterogeneous access networks with autonomic optimisation of network performance and availability.
Article
Full-text available
This paper presents the RASCAL System, a middleware component able to palpably ensure that user-level services communi- cating across infrastructure or ad-hoc networks continue to work even when deployed in disruptive environments such as major incidents sites. By palpable we mean that users should be able to notice, comprehend communication action...
Article
Full-text available
In this paper we propose an insect-based algorithm for tackling the Dynamic Task Allocation (DTA) problem, a fac- tory scheduling problem in which tasks are to be allocated to processing units. In previous works, multi-agent algorithms have been developed for the homogeneous case, that is, the case in which all agents (processing units) are identic...
Article

This paper presents RASCAL, a contingency man-ager system with autonomic capabilities which enables collab-oration among a set of ubiquitous services deployed in the infrastructure and/or in the ad-hoc network. Autonomicity is shown in the context of disruptive environments, that is, a series of locations that may be subject to intermittent or comp...

... This great amount of technologies, requires compatibility solutions. Some works, like the RASCAL sys- tem [41], allow mobile devices to autonomically self-manage connection endpoints and data transmission over available network technologies, providing a contingency manager system with autonomic capabilities which enables collaboration among a set of ubiquitous services deployed in the infrastructure and/or in the ad-hoc network . Other works, like ASAM [9] , Adaptive Service Access Management, enables effective delivery of next generation ubiquitous services by dynamically combining end user requirements and service provisioning policies with network-facing management and control functionality. ...
... Lastly, such a middleware will hide the heterogeneity of computer architectures, operating systems, programming languages, and networking technologies to facilitate application programming and management. As assumed by [9], this is done through easing the transformation of markup languages, delivery of content and data, recognition of protocols and devices, incorporation of and routing of business logic through enterprise systems and the adaptation of data formats for compatibility with multiple databases. In USN middleware approaches, how the network is abstracted is an important parameter that determines how the user wanting access to the network's data will interact with the USN. ...
... Without limits on task availability and without inter-agent communication, many existing task allocation approaches become unsuitable. Auctions and dominance contests for assigning a limited number of unit jobs require communication and limits on task availability: once an agent wins a task in an auction, others cannot win that same task, which reduces their choices Nunes and Gini 2015;Nunes et al. 2016;Zheng and Koenig 2011;Campos et al. 2000;Cicirello and Smith 2004;Ghizzioli et al. 2005;Nouyan 2002;Nouyan et al. 2005). Applying these approaches to ongoing tasks requires an artificial discretization of continuous system needs into individually assignable unit jobs. ...
... Considering more specifically the KAOS approach, the Goal-Oriented Business Process Modelling Notation (GO-BPMN) is a language enhancing standard BPMN with support for the explicit modelling of goals, plans and their relationships (Greenwood and Ghizzioli, 2009). A GO-BPMN model consists of a set of goal hierarchies (similar to KAOS) that must be achieved or maintained. ...
... In so doing, we aim at exploiting some the foundational features of the agent paradigm [15] to seamlessly tackle with a single computational model all those aspects that are put forth by actual SOA models. In this view we here promote the capability to integrate both a task-oriented/process-oriented behaviour – such in the case of agent based workflows [2] or goal oriented business pro- cesses [27] – and a reactive (even-driven) behaviour, such in the case of Event-Driven Architectures (EDA), which are meant to be a main aspect of SOA 2.0 5 . ...
... This model has gained wide acceptance in the multi-agent systems community. Early studies [Campos et al. 2000;Cicirello and Smith 2002a;Kittithreerapronchai and Anderson 2003;Nouyan et al. 2005] focus on Morley's paintshop problem [Morley 1996]. This model has also been applied to problem domains such as mail processing [Goldingay and van Mourik 2013;Price and Tino 2004], foraging [Castello et al. 2016[Castello et al. , 2018[Castello et al. , 2013Lee and Kim 2019;Lee et al. 2020;Pang et al. 2017], RoboCup rescue [Ferreira et al. 2007], UAV monitoring [Amorim et al. 2020;Schwarzrock et al. 2018], as well as abstract task allocation problems [Correll 2008;de Lope et al. 2013;dos Santos and Bazzan 2009;Ferreira et al. 2007;Merkle and Middendorf 2004;Niccolini et al. 2010]. ...
