11. How is ontology different from object-oriented modeling? An ontology is different from object-oriented modeling (represented in UML) in several ways. First, the most profound difference is that the ontology technology is theoretically found on logic. While ontology allows automated reasoning or infer ence, object-oriented modeling does not. Another difference is the treatment of properties; while the ontology technology treats properties as the first-class citizen, the object-oriented modeling does not. That is, while the ontology technology allows inheritance of properties, the object-oriented modeling does not. While the ontology technology allows arbitrary user-defined relationships among classes (a type property), the object-oriented modeling limits the relationship types to the subclass-superclass hierarchical relationship. While the ontology technology allows adding properties to relationships such as symmetry, transitivity, and inversion so that they are used in reasoning, the object-oriented modeling does not. While the ontology technology allows multiple inheritances among classes and also among properties, the object-oriented modeling allows only single inheritances. Despite theses differences, object-oriented modeling and UML are accepted as a practical ontology specification, mostly because of their wide-spread use in industry and the multitude of existing models in UML. There is an on-going effort to add logic capability to object-oriented modeling, represented by OCL (Object Constraint Language).

daviding says: To improve our understanding of the science of service systems, I think that we need to get to the level of ontology vocabulary ... and probably no higher. SysML has features that UML doesn't ... which doesn't mean good or bad, just different.

Inspired by complexity theory and open source thinking, the Constellation Model provides a framework to help organizations collaborate. The organizing model emphasizes the role of small, self-selecting action teams that operate interdependently, supported by a Stewardship Group. Leadership rotates fluidly among partners, where each partner has the freedom to lead a constellation that matches its profile and skills. The result is a shift from strained partnerships to open and effective collaborations. This organizing model is a true social innovation. Initially created and refined with the Canadian Partnership for Children's Health and Environment, the Constellation Model has been replicated and adapted to support the work of a dozen groups. Join Tonya Surman, creator of the model, as she explains how the model works and takes on your collaboration challenge! This is an ideal workshop for groups that are exploring what kind of a collaboration might work for their project or for learners exploring new models of organizing.

OMG™ and the International Council on Systems Engineering (INCOSE) today announced that they have agreed to work together on the development of OMG's new program to certify Systems Engineers and other practitioners on the OMG Systems Modeling Language (OMG SysML™) standard. SysML is a graphical modeling language used to perform Model-Based Systems Engineering (MBSE) - that is, to specify and design complex systems that may include hardware, information, personnel, and facilities in addition to software. The program, to be called OCSMP™ (OMG-Certified Systems Modeling Professional), will be OMG's fourth certification. OMG, an international, open membership, not-for-profit industry consortium, maintains standards for interoperability, modeling, and process maturity including the Model Driven Architecture® (MDA®) and Unified Modeling Language™ (UML®); in addition, OMG certifies practitioners in many of these standards. INCOSE is a not-for-profit membership organization dedicated to advancing the state of the art and practice of systems engineering, in part through its Certified Systems Engineering Professional (CSEP) certification program.

The hard (in the sense of difficult) part of service science is the social system side. INCOSE and OMG don't really address that. They address the hard (as opposed to soft) systems aspects, with people merely as more parts of an intrinsically engineered system (weapons system, transportation system, etc.). I applaud your diligence with respect to SysML and all that, but I hope your vision of the science of service systems is big enough to include the social side as well.

UMM is based in UML, which means it's about modeling the information aspects of businesses. This Wikipedia entry seems underdeveloped, so the description should taken with a grain of salt. It does point out that UMM attempts to decouple from implementation technologies such as Web Services and ebXML.

UN/CEFACT's Modeling Methodology, commonly known as UMM is a modeling methodology which is developed by UN/CEFACT - United Nations Center for Trade Facilitation and Electronic Business. Goal of UMM The primary goal of UMM is to caputure business requirements of inter-organizational business processes. These requirements result in a platform independent UMM model. The UMM model can then be used to derive deployment artifacts for the IT systems of the participating business partners. UMM at a glance UMM enables to capture business knowledge independent of the underlying implementation technology, like Web Services or ebXML. The goal is to specify a global choreography of a business collaboration serving as an "agreement" between the participating partners in the respective collaboration. Each business partner derives in turn its local choreography, enabling the configuration of the business partner's system for the use within a service oriented architecture ( SOA).

The research presented in this volume, developed in the EC-funded Project ISCOM (Information Society as a Complex System), takes off from two fundamental premises: -- to guide innovation policies, taking account of the social, economic and geographic dimensions of innovation processes are at least as critical as the science and technology; and -- complex systems science is essential for understanding these dimensions.

About this site The site http://www.umm-dev.org serves as a central access point for all information related to UN/CEFACT's Modeling Methodology (UMM) and the UML Profile for Core Components (UPCC). It provides information about the UMM and UPCC standard per se, academic work in the field of inter-organizational business process modeling and business document as well as tools and other important resources.

This site is a Wordpress blog, so it's possible/practical to receive a feed about ongoing development of the UMM. (The alternative may be the e-mail list). The work appears to be largely centered at universities in Austria.

Background Marital dissolution is ubiquitous in western societies. It poses major scientific and sociological problems both in theoretical and therapeutic terms. Scholars and therapists agree on the existence of a sort of second law of thermodynamics for sentimental relationships. Effort is required to sustain them. Love is not enough. Methodology/Principal Findings Building on a simple version of the second law we use optimal control theory as a novel approach to model sentimental dynamics. Our analysis is consistent with sociological data. We show that, when both partners have similar emotional attributes, there is an optimal effort policy yielding a durable happy union. This policy is prey to structural destabilization resulting from a combination of two factors: there is an effort gap because the optimal policy always entails discomfort and there is a tendency to lower effort to non-sustaining levels due to the instability of the dynamics. Conclusions/Significance These mathematical facts implied by the model unveil an underlying mechanism that may explain couple disruption in real scenarios. Within this framework the apparent paradox that a union consistently planned to last forever will probably break up is explained as a mechanistic consequence of the second law.

daviding says: Entropy may play not only in marriages, but also in service relationships.

The Energy Systems Language (right), also referred to as Energese, Energy Circuit Language and Generic Systems Symbols, was developed by the ecologist Howard T. Odum and colleagues in the 1950s during studies of the tropical forests funded by the United States Atomic Energy Commission. They are used to compose energy flow diagrams in the field of systems ecology.

I was looking at the Systems Modeling Language page on Wikipedia, and noticed this link to Energy Systems Language, by Howard Odum. It's an interesting idea ... although it brings questions to the choice of modeling languages and approaches. No model is value-free.

At the UN -- actually the United Nations Economic Commission for Europe -- ther version 1 models and metamodels dated 2006 are published.

daviding says: Although the title says "price", informal ties reduce the cost of client interactions because the effort to transfer information on complex issues is lower.

... they modeled three features: how firms' prices changed with respect to the number of embedded ties they had with clients; the number of the firm's attorneys who sat on the boards of other corporations; and the status of the firm as perceived by peers. The greater the proportion of informal relationships and unwritten arrangements a firm enjoyed with clients, the lower the fee the firm typically charged for complex legal work. Such ties promote clearer understanding of client needs and preferences and lessen the need for rigid oversight structures, allowing for more efficient and timely operation, thus requiring less billable time from a firm. Said one partner: "It's no question that trust enters into [pricing]. I mean, it's very rare that you're going to get the big $500 million transactions-I don't see them with a stranger." Said another: "A relationship allows [the client] to be more nimble with our firm; rather than having a formal engagement in a project, she may call a partner she knows directly-so it's very efficient for her." Besides promoting the flow of private, valuable information between firm and client, network ties can give the firm access to useful information flowing between other parties. In particular, a firm can benefit significantly if its attorneys sit on corporate boards. One attorney described two notable advantages of board membership this way: "You have the benefit of seeing what other law firms are charging if the company that you sit on is using other firms. . . . And you get the benefit of the commentary that your fellow board people have on legal services and what they consider to be important." As a result of this privileged information, firms whose partners sit on corporate boards are able to charge higher rates for both routine and complex legal work. Law firms perceived to have high social status are able to offer image-enhancing benefits to its clients, since the clients will appear knowledgeable

daviding says: Categorizing problems as P-type, N-type and NP-type (i.e. NP-hard) provides a way for appreciating why managers avoid taking on some challenges. It's better to succeed on an easy problem, than fail on a hard one. (There's a easier-reading version of this article in Rotman Magazine Winter 2009 that seems to have been evolved for publication into Harvard Business Review in January 2009).

[from the introduction] We develop a model of cognitive choices managers implicitly make among and within problem complexity classes and argue that strategic managers use problem statements from one complexity class with greater regularity than those from other complexity classes to make sense of their predicaments (i.e. to transform 'situations' or 'raw feels' into 'problems' or 'puzzles'). We examine the marginal value to strategic managers of greater 'logical complexity' - parametrized by the marginal value of greater precision of an answer and the computational sophistication of competitors schema - to come up with a computationally precise formulation of 'ecological rationality'.

Building on the success of the original INNOV8 in the academic community, INNOV8 v.2 will be available at no cost to businesses and academic institutions for simulations and training. The new version features puzzles and tasks that challenge players to tackle real-world challenges. INNOV8 v.2 delivers a complete redesign of the game, with a new global collaboration feature for players to work with virtual teammates to progress to the next level of the game. In addition, three new game scenarios reflect a new level of intelligence required for future, high-value job opportunities: * 'Green' Supply Chain: Players evaluate a traditional supply chain model and are tasked with reducing a fictional company's carbon footprint. * Efficient Traffic Flow: Players evaluate existing traffic patterns and re-route traffic based on sensors that alert the player to disruptions such as accidents and roadway congestion. * Call Center Customer Service: Using a call center environment, players develop more efficient ways to respond to customers. [....] Most MBA programs are already heavily based on projects that reflect how individuals and teams need to interact in the real world. INNOV8 v.2 takes that a step further by actually allowing students to step into a dynamic business environment. Based on advanced commercial gaming technologies, it allows players to visualize how technology and related business strategies affect an organization's performance. Together, players can map out business processes, identify bottlenecks and explore 'what if' scenarios in an experiential learning environment. [....] INNOV8 v.2 will be available in May 2009. For more information on INNOV8, IBM's Academic Initiative or to access the virtual press kit, pleas visit www.ibm.com/innov8.

daviding says: The main page is at http://www-01.ibm.com/software/solutions/soa/innov8/index.html . I haven't played the game -- I'm not a fan of video games -- so if you want to try 5 to 10 minutes online, I'd be interested in your experience.

Wayne Wymore is now well established as an important leader in systems engineering and a founder of a highly original "school of thought" in the area of systems design. His contribution to this area, which will be the subject of a special issue of this journal in the near future, is best exposed in a trilogy consisting of this book and its two predecessors [Wymore, 1967, 1976]. Wymore's approach to systems design is characterized by mathematical rigor, comprehensiveness, and broad applicability. This book is, in some sense; the most complete presentation of his approach, even though it is restricted (contrary to its predecessors) to discrete systems. [....]

daviding says: At the 2010 INCOSE Workshop on Autonomous System Testing and Evaluation, Jack Ring cited a "Wymorian approach", which is based on "A mathematical theory of systems engineering: the elements" by A. Wayne Wymore (see http://books.google.ca/books?id=yXrsAAAAIAAJ , unfortunately without a full preview). This may be at the foundations of the current interest in MBSE at INCOSE as a major initiative. The 1993 book is previewable at http://books.google.ca/books?id=CLgsYC3K2yAC .

We introduce the concept of structural analysis of a business enterprise. The practice of enterprise structural analysis amounts to the construction of an enterprise model using business entities defined in an enterprise ontology or enterprise architecture and creating specific views of the enterprise based on relationships among the entities. As we demonstrate through a simple yet illustrative example of a hypothetical coffee shop business, these views can provide many insights and points of analysis. Structural analysis provides an interactive, analytical environment for a user to view an enterprise from multiple perspectives, an approach not unlike On-Line Analytical Processing (OLAP) but for analyzing the qualitative or structural aspects of the enterprise.

daviding says: This article describes business entities, and works concretely through an example with activities, resources and organization in a coffee shop.

Conference on Systems Engineering Research Stevens Institute of Technology and Delft University of Technology in collaboration with the University of Southern California (USC), presents the 8th Annual Conference on Systems Engineering Research (CSER) Conference Objective The objective of this conference is to provide practitioners and researchers in academia, industry, and government with a common platform to present, discuss and influence Systems Engineering research, and to enhance the practice of Systems Engineering and Systems Engineering education. Call for Papers We invite original research papers addressing any aspect of the Systems Engineering lifecycle. This includes conception, design and architecting, development, modeling and simulation, production, integration, validation, operation and support of these systems. Additional topics include definition of metrics, performance, and improvement methods, assessment and mitigation of risks, definition of critical success factors, and definition of best practices. All papers will be peer reviewed, and if accepted, presented at the conference.

daviding says: I have this conference marked on my calendar. The Nov. 1 paper deadline is tough for me. In addition, I should also be working on my dissertation in the spring ... and that's not on a systems engineering topic.

This 4-minute video is worth watching. It introduces a language for modeling the ecology. At http://www.youtube.com/user/leearnold , it states "the symbols were drawn in Adobe Illustrator, then animated in Adobe After Effects", which means that there isn't good tool support for Ecolanguage, and thus takes a lot of work to construct and maintain these videos.

Video (4 minutes) by Lee Arnold that introduces Ecolanguage. At 0:50, the voiceover and slide say that Ecolanguage was inspired by Howard T. Odum's book, "Environment, Power and Society", 1971.

The Royal Society has recently published the findings of a major study on the role of science in services sector innovation. Entitled Hidden Wealth: the contribution of science to service sector innovation , the report highlights the wider significance of science, technology, engineering, and mathematics (STEM) to the services sector, which makes up around three quarters of the UK economy. Hidden Wealth concludes that STEM is deeply embedded within the UK service sectors and has an extensive impact on service innovation processes, which is often hidden. Although STEM is important in services sector innovation now, it is also likely to play an important part in the future of services, as many services are on the cusp of a transition to more personalised and interconnected systems, which will require significant advances in STEM.

This report from the Royal Society was cited by Irving Wladawsky-Berger at http://blog.irvingwb.com/blog/2009/08/hidden-wealth-science-technology-and-services-innovation-in-the-21st-century.html .

Excerpt: 6.6.6 A systems-based approach to understanding services. One solution may lie in the wider adoption of systems-based approaches to understanding services. A more systematic approach to studying services should result in better design, management and understanding of services and, at the same time, provide a suitable context in which to integrate disciplines such as social sciences, management science, economics and STEM. These sorts of educational programmes may particularly benefit firms who do not require graduates with deep knowledge in one of the existing disciplines. [p. 61] However, we note that when this has been attempted in the past, as with systems science and complexity theory -- both of which have existed for several decades and have been widely applied in scientific, engineering and social science contexts -- the tendency has been for people to organise themselves into disciplinary silos, with the result that the desired new interdisciplinary approaches have struggled to impose themselves. [pp. 61-62] The emerging Service Science, Manufacturing and Engineering (SSME) or 'Service Science' concept is also intended to join up a broad range of disciplines, but is specifically concerned with ensuring that graduates are better equipped for the workplace. Service Science may ultimately help the development of multi-disciplinary capabilities but in this regard SSME programmes seem to have been slow to emerge and only partially successful to date. A more profitable approach to redesigning academic curricula and delivery (at least as far as services are concerned) may be to focus in on service design, which seeks to understand the delivery of services from a user perspective and to develop better solutions (see Box 4.3 on page 40). Developments such as the Masters course in Service Design, Management and Innovation offered by the University of Manchester Centre for Service Research might provide good models for new courses, and should be closely mon
