Towards a Constraint-Based Framework for Dynamic Business Process Adaptation

Today’s ever-changing business environments, comprised among other things of customer expectations, market demands, and legal obligations, require dynamic and adaptive business processes. Hence, enterprises need to monitor and improve their business processes against their business goals and constraints. Aspect-oriented development is known to have helped designers cope with changing concerns in software, even dynamically. In this paper, we perform a systematic literature review of aspect-oriented approaches for business process adaptation. We observe that current methods focus on i) composing and swapping services based on Quality of Service (QoS), cost, rules, policies, and constraints, as well as in the event of failure, ii) extracting roles and crosscutting concerns from composite services, iii) customizing process instances based on user profiles or Service Level Agreements, iv) adapting service composition and collaboration policies, and v) using monitoring aspects to detect undesired situations. This review also suggests that our own aspect-oriented process modeling and adaptation framework is novel because none of the other approaches considers organization goals, performance and constraints as a whole when improving business processes. In addition, given much prior research on aspect-oriented service composition is available, we are confident that our modeling framework is realizable.

“…Eijndhoven et al (2008), Hermosillo et al (2010b), Hermosillo et al (2010a) fall into this level of dynamicity, since their main idea is to define decision points in a process and describe those decisions through business rules. The approach, presented in (Xiao et al, 2011), also falls into this level of dynamicity. Although Xiao et al (2011) suggest constructing a process from a number of reusable fragments, new process schemas generated according to the new conditions are applicable only at the next process instance execution (Berkane et al, 2012).…”

“…As the analysis shows, the biggest part of the approaches is implemented as a case study, like in (Mejia Bernal et al, 2010;Hermosillo et al, 2010b;Kwan and Balasubramanian, 1997), or an automation of the proposed approach at some level. For example, as presented in (Xiao et al, 2011), the proposed implementation (i.e. automation) of the approach allows for changing BP by presenting several different instances of the changed BP, or by presenting templates for BP execution, like in (Eijndhoven et al, 2008).…”

“…it is independent of the implementation solutions, which could be used to implement it. For example, a service-oriented approach (SOA) may be used for the implementation of the architecture, like in (Hermosillo, 2012;Marrella and Mecella, 2011;Xiao et al, 2011;Berkane et al, 2012); the authors use a SOA for rules execution. This does not mean that other ways of implementing DBP are neglected.…”

Olegas Vasilecas, Diana Kalibatiene and Dejan Lavbič. 2016. Rule-and context-based dynamic business process modelling and simulation, Journal of Systems and Software (JSS), 122, pp. 1 -15. AbstractThe traditional approach used to implement a business process (BP) in today's information systems (IS) no longer covers the actual needs of the dynamically changing business. Therefore, a necessity for a new approach of dynamic business process (DBP) modelling and simulation has arisen. To date, existing approaches to DBP modelling and simulation have been incomplete, i.e. they lack theory or a case study or both. Furthermore, there is no commonly accepted definition of BDP. Current BP modelling tools are suitable almost solely for the modelling and simulation of a static BP that strictly prescribes which activities, and in which sequence, to execute. Usually, a DBP is not defined strictly at the beginning of its execution, and it changes under new conditions at runtime. In our paper, we propose six requirements of DBP and an approach for rule-and context-based DBP modelling and simulation. The approach is based on changing BP rules, BP actions and their sequences at process instance runtime, according to the new business system context. Based on the proposed approach, a reference architecture and prototype of a DBP simulation tool were developed. Modelling and simulation were carried out using this prototype, and the case study shows correspondence to the needs of dynamically changing business, as well as possibilities for modelling and simulating DBP.

“…The problem for adaptive and flexible service compositions has been studied by some works [4], where binding and re-binding of composite services, often driven by Quality of Service (QoS) goals [8], is an important concern for IT services to determine the best and optimized service sequence. Therefore, capturing and modeling the variability of business process models and their orchestrations [20,15] for supporting dynamic business process adaptation [29] results key for DSPL approaches that use context information and runtime variability mechanisms to determine the most suitable service selection and composition during service reconfiguration operations [2]. Other experiences define the notion of smart workflow to compose di↵erent user tasks depending on the context information or data gathered from di↵erent inputs (e.g.…”

In emerging domains such as Cloud-based Industrial Control Systems (ICSs) and SCADA systems where data-intensive and high performance computing are needed, a higher degree of flexibility is being demanded to meet new stakeholder requirements, context changes and intrinsic complexity. In this light, Dynamic Software Product Lines (DSPLs) provide a way to build self-managing systems exploiting traditional product line engineering concepts at runtime. Although context-awareness is widely perceived to be a firstclass concern in such runtime variability mechanisms, existing approaches do not provide the necessary level of formalization to model and enact context variability for DSPLs. This is crucial for operational analytics processes since variant configuration could di↵er from context to context depending on diverse data values linked to context features and cross-tree constraints in a feature model. In this paper, we propose a context variability modeling approach, demonstrate its applicability and usability via a wind farm use case, and present the fundamental building blocks of a framework for enabling context variability in service-based DSPLs which provide Workflow as a Service (WFaaS).
