It involves structuring and solving the problem, and interpreting the results. A computer-based environment that supports these decision making processes is characterised by a modelling approach that enables the representation of the complexity of the problem, access to data and solvers, persistence of problem representation, and the ability to manipulate and integrate problem representations. Lack of a general framework for conceptual modelling and constraints imposed by technology have, in the past, limited the design and implementation of enterprise model management systems (EMMS). This research attempts to overcome key problems in EMMS design and implementation by proposing, implementing, and evaluating a modelling framework that uses Structured Modelling to describe models, object-oriented and relational constructs to represent models, and predicate calculus-based extended Structured Query Language (ESQL) to manipulate models.

Current Spatial Decision Support Systems (SDSS) fulfil their specific objectives, but fail to address many of the requirements for effective spatial problem solving, as they are inflexible, complex to use and often domain-specific. As technology progresses, there is an increasing opportunity for the use of SDSS in a number of domains. Flexible support for spatial decisionmaking to solve complex, semi-structured or unstructured spatial problems can offer advantages to individuals and organisations.

The root cause for this is the lack of a holistic and integrated view on knowledge sharing. Globalisation and the increased speed of operations in the business world have led to dramatic changes in organisational life; the traditional way of working is no longer competitive. One of the critical factors determining the success of an enterprise nowadays is the ability to share knowledge, despite hierarchical structure, geographical barriers, and the age and experience of employees. There has been abundant research into knowledge management and knowledge sharing. However, most of the literature devoted to knowledge sharing has approached the problem from a range of perspectives: strategic, managerial, behavioral, participatory, relational, process, contextual and/or technological. This research reviews knowledge-sharing problems and issues with the purpose of sy...

Among these, the rational and anarchical models have emerged as important representations of decision-making dynamics. The rational model and its variants of decision making emphasize recognized phases and sequence among them, while anarchical models focus on the lack of structure and sequence in many real-world decision-making contexts. In order to observe the existence of these phases and their sequence, it is critical to choose non-trivial situations in which the underlying dynamics of decision-making process are readily visible. To this end, we consider decisionmaking (DM) in Health Online Social Networks (HOSN) and verify the existence of recognized phases and the sequence in which these phases are reached. We use netnography to explore the potential of HOSN as a support tool for decision-making process. Our results confirm, extend, as well as challenge existing knowledge. Results confirm that HOSN support and empower users during their decision-making process in three specific key phases that include Intelligence, Design and Choice. We extend existing knowledge by suggesting two new phases in the decision making process that is integral to HOSN conversations, namely emotional support and sharing experiences. Our results challenge purely rational and anarchical models by recognizing the interweaving of anarchical decision sequences within the structure of rational decision making phases. These results have significant practical implications for the design of HOSN that support blended decision making processes by leveraging the wisdom of crowds.

Businesses and their supply chains often follow this trend, as environmental and social initiatives tend to be disconnected from overall strategies. Most sustainability frameworks are not directly applicable to the inherent complexity of supply chains. Supply chains need to address the sustainability dimensions in a strategic way that encompasses all stakeholders and aligns supply chain goals with the aims of individual members. Supply chains have to adjust their transformation strategy depending on the level of maturity. Our research proposes a model that integrates sustainability in supply chains with maturity considerations. Furthermore a sustainability modeling and reporting system is developed that facilitates a progression towards higher maturity levels. The proposed artifacts leverage the features from established frameworks and may be used in a prescriptive manner for design and implementation.

The visualization capability of a BI system in terms of developing effective visualizations for addressing business problems is crucial to the success of BI. With the rapid advances achieved in the domain of information visualization, many existing visualization techniques/applications can provide reasonable support for particular paradigms, problem domains, and data types. However, they are still weak for supporting multi-paradigm, multi-domain problems and maintaining visualization effectiveness under dynamic contexts. BI systems need to include visualization subsystems or be used together with separate visualization systems that offer flexible support for creating, manipulating and transforming visualization solutions. In this paper, we discuss business visualization context and propose and implement a context adaptive visualization framework. Furthermore, we demonstrate the framework implementation through a sequence of context-driven illustrations.

The effectiveness of adopting certain visualizations towards fulfilling the purposes may be significantly affected by both the decisional problem context within which the visualization is deployed and the situational context of the viewers.

When it comes to upgrading their legacy processes, middleware systems have their own particular requirements and complexities that standard upgrade roadmaps are incapable of fully addressing. In particular, legacy processes that cannot be upgraded using vendor or market tools due to the lack of knowledge about their mechanisms or due to their complexity represent a challenge to upgrade projects. This paper proposes a roadmap to address this challenge by offering a side-by-side approach to migrate unupgradable legacy processes in middleware systems with minimum business and financial impact.

While decision support technologies have been studied for a number of years the emergence of new standards and internet technologies provides us with an opportunity to address current problems in distributed and collaborative decision making. This class of problems has become increasingly relevant with collaborative business models such as supply and demand chains and e-business. In particular, the increasing global nature of organizational work involves collaboration across national boundaries. This has become a common business model and technology support for such activity is the focus of our work. In this paper we discuss the design of a generator that supports distributed decision making. We do this by leveraging emerging standards and technologies like Web Services, SOAP, and WSDL. Features such as ad-hoc integration, location independence and platform independence are supported in a manner that addresses independence, flexibility, interoperability, and workflow management. We present a discussion about a design prototype and associated examples using the stock market as an application domain.
