Decision-enabled dynamic process management for networked enterprises

Enterprises in today’s networked economy face numerous information management challenges, both from a process management perspective as well as a decision support perspective. While there have been significant relevant advances in the areas of business process management as well as decision sciences, several open research issues exist. In this paper, we highlight the following key challenges. First, current process modeling and management techniques lack in providing a seamless integration of decision models and tools in existing business processes, which is critical to achieve organizational objectives. Second, given the dynamic nature of business processes in networked enterprises, process management approaches that enable organizations to react to business process changes in an agile manner are required. Third, current state-of-the-art decision model management techniques are not particularly amenable to distributed settings in networked enterprises, which limits the sharing and reuse of models in different contexts, including their utility within managing business processes. In this paper, we present a framework for decision-enabled dynamic process management that addresses these challenges. The framework builds on computational formalisms, including the structured modeling paradigm for representing decision models, and hierarchical task networks from the artificial intelligence (AI) planning area for process modeling. Within the framework, interleaved process planning (modeling), execution and monitoring for dynamic process management throughout the process lifecycle is proposed. A service-oriented architecture combined with advances from the semantic Web field for model management support within business processes is proposed.

Electronic negotiation systems have been devised to create an electronic marketplace for bargaining, auctions, reverse auctions, and exchanges between multiple buyers and sellers. Most studies of negotiation systems concentrate on negotiation process modeling and data modeling - rather than on strategies and efficiency - for a multiple-criteria decision making (MCDM) problem in which many criteria are taken into account as attributes for decision making. This study proposes an active collaboration and negotiation framework (ACNF), which is a negotiation support system that uses active documents with embedded business logics or business rules that can adapt to different collaborative strategies in a business-to-business (B2B) environment. The risk preferences of negotiators are modeled and measured by utility functions that provide mathematical tools to compute the relative value of different courses of action. The system is demonstrated, and three experiments are conducted to validate its performance. The experiments show that the negotiation process is very efficient, and the results are both close to the efficient point - and the Pareto frontier - and are fair to both negotiating parties. The framework can be used to efficiently and effectively achieve a settlement in various multiple-criteria bargaining schemes in the electronic marketplace     

Building a Multiple-Criteria Negotiation Support System

Electronic negotiation systems have been devised to create an electronic marketplace for bargaining, auctions, reverse auctions, and exchanges between multiple buyers and sellers. Most studies of negotiation systems concentrate on negotiation process modeling and data modeling?rather than on strategies and efficiency?for a multiple-criteria decision making (MCDM) problem in which many criteria are taken into account as attributes for decision making. This study proposes an active collaboration and negotiation framework (ACNF), which is a negotiation support system that uses active documents with embedded business logics or business rules that can adapt to different collaborative strategies in a business-to-business (B2B) environment. The risk preferences of negotiators are modeled and measured by utility functions that provide mathematical tools to compute the relative value of different courses of action. The system is demonstrated, and three experiments are conducted to validate its performance. The experiments show that the negotiation process is very efficient, and the results are both close to the efficient point?or the Pareto frontier?and are fair to both negotiating parties. The framework can be used to efficiently and effectively achieve a settlement in various multiple-criteria bargaining schemes in the electronic marketplace.     

An end-user approach to business process modeling

This paper discusses the main differences between humanistic and mechanistic business process modeling. While the mechanistic approach requires strict process formalization, emphasizes technical details, and constrains the modeling task to technology experts, the humanistic approach is more centered on the end-user. We developed a modeling approach and a collaborative tool supporting end-user business process modeling. Design storyboards were adopted as a paradigm for knowledge representation and visual composition. The main contributions from this research include the knowledge representation structure and a collaborative tool supporting visual composition of business process models.     

A reference model of virtual service production networks

Virtual organisation of collaborative networks frequently demands for information and communication technology to support coordination of cross-organisational business process chains. Service-oriented software technologies provide promising means to regulate and enforce coordination of cross-organisational software service interactions but miss organisational abstractions and methodology. This paper proposes a conceptual reference model of collaborative network coordination that satisfies flexibility and agility requirements of virtual organisation by building on common software service abstractions and lifecycle methodology. In particular, the model focuses collaborative service networks and introduces the concept of virtual business service that represents business service processes as software service abstractions and supports flexible regulation and agile enforcement of their coordination by means of software service lifecycle methodology. For demonstration and evaluation purpose, we present a case study of service-oriented systems analysis for virtual organisation of a collaborative e-science network that adopts our conceptual reference model.     

Reasoning on infeasibility in distributed collaborative computing environment

Collaborative computing is a new communication technology that makes it possible to extend model formulation, management, and analysis into a geographically distributed group environment. The forms of communication may vary from asynchronous hypermedia teamwork via the Internet to multipoint desktop video conferencing. The latter presents the maximal potential for integrating shared quantitative model analysis with real-time/asynchronous geographically distributed electronic meetings. Infeasibility diagnosis and reasoning on conflict resolution are known to be important parts of an evolving approach to linear programming model analysis. In the new distributed environment, several specific decision support issues related to infeasibility analysis emerge. One is the learning mechanism for capturing group knowledge on infeasibility resolution that is generated during the collaborative sessions of model analysis. The other new decision support component is a coordination protocol that is capable of linking individual activities and software transactions for the support of group reasoning on infeasibility analysis. This paper addresses these issues on the basis of committee models for infeasibility resolution and the neural network approach. Examples of modeling cases are based on experiments using a multiple criteria model for support of resource allocation in a distributed electronic meeting, and the case of model-based diagnosis that the group is involved in.     

How collaborative technology supports cognitive processes in collaborative process modeling: A capabilities-gains-outcome model

We examine which capabilities technologies provide to support collaborative process modeling. We develop a model that explains how technology capabilities impact cognitive group processes, and how they lead to improved modeling outcomes and positive technology beliefs. We test this model through a free simulation experiment of collaborative process modelers structured around a set of modeling tasks. With our study, we provide an understanding of the process of collaborative process modeling, and detail implications for research and guidelines for the practical design of collaborative process modeling.
