Goel, Asvin and Volker Gruhn (2008): A General Vehicle Routing Problem, European Journal of Operational Research, 191 (3): 650-660.
Abstract: In this paper, we study a rich vehicle routing problem incorporating various complexities found in real-life applications. The General Vehicle Routing Problem (GVRP) is a combined load acceptance and generalised vehicle routing problem. Among the real-life requirements are time window restrictions, a heterogeneous vehicle fleet with different travel times, travel costs and capacity, multi-dimensional capacity constraints, order/vehicle compatibility constraints, orders with multiple pickup, delivery and service locations, different start and end locations for vehicles, and route restrictions for vehicles. The GVRP is highly constrained and the search space is likely to contain many solutions such that it is impossible to go from one solution to another using a single neighbourhood structure. Therefore, we propose iterative improvement approaches based on the idea of changing the neighbourhood structure during the search.

Raasch, Christina, Cornelius Herstatt and Phillip Lock (2008): The dynamics of user innovation: Drivers and impediments of innovation activities, International Journal of Innovation Management, 12 (3): 377-398.
Abstract: Users have proven to be a principal driving force of many innovations in different industries. Therefore, more and more firms try to identify avenues to systematically involve users into their new product development. Despite the growing interest in user-driven or user-centred innovation, both in academia and industry, the drivers and impediments affecting the evolvement of user innovation activities over time have only recently become a focus of analysis. This study aims to examine user innovation over time and contribute to the extension of the existing model of user-driven innovation to a more dynamic setting. For this purpose, we study the evolution of user innovation in a field of sports equipment, a high-performance sailboat called Moth. We analyse innovation activities over several decades based on secondary data, interviews and survey results. We find that the level of user activity does not follow a unidirectional trend, but rather develops depending on a number of contextual factors. This suggests that, given a stimulating setting, user innovation can be sustained over long periods of time.

Abstract: We analyzed the text of more than 1,000 ads for operations research (OR) jobs. Our objective was to help industry employers benchmark the skills they are seeking in OR graduates with those that other employers are seeking. Educators can also compare their offerings against the skills industry employers seek. We found that employers of OR graduates consistently require modeling, statistics, programming, and general analytical skills in an operations management context as their primary requirements regardless of sector, function within company, and even degree type. These employers also require communication, leadership, project management, spreadsheet and database, and team skills in that order.

Abstract: Purpose – Service‐oriented architecture (SOA) is an architecture paradigm targeting integration of applications within and across enterprise boundaries. It has gathered research and industry acceptance and has given an enormous impetus to the business process management technology. Web service (WS) technology is one implementation of the SOA paradigm. It enables seamless integration of new and legacy applications through a stack of standardized composable specifications. WS orchestration is facilitated by the Business Process Execution Language which provides a recursive service composition model. While the programming model the WS technology provides is very flexible, a major deficiency is the need to discover services implementing a particular abstract interface, whereas functional similarities of services are disregarded. The Semantic Web Service technologies, like Web Service Modelling Ontology (WSMO) and Web Ontology Language for Services have been developed with the purpose of eliminating these deficiencies by enabling service discovery based on functional and non‐functional properties. The paper aims to focus on these issues.Design/methodology/approach – This paper presents a list of requirements that business processes impose on SOA applications. It analyzes the support that WSMO/Web Service Model eXecution environment (WSMX) provides to address these requirements and compares it with the support enabled by the WS specification stack.Findings – The paper identifies major flaws in the WSMO model and its reference implementation with respect to business process support.Originality/value – The paper recommends possible solutions for eliminating the lack of needed features on behalf of WSMO/WSMX. It presents in detail how to enable asynchronous stateful communication among WSMO WS and partner‐based WS discovery by extending the WSMO model. Additionally, it extends the API of the reference implementation to facilitate the execution of services communicating asynchronously.

Momotko, Mariusz, Michał Gajewski, André Ludwig, Ryszard Kowalczyk, Marek Kowalkiewicz and Jian Ying Zhang (2007): Towards adaptive management of QoS-aware service compositions, Multiagent Grid System, 3 (3): 299-312.
Abstract: Service compositions enable users to realize their complex needs as a single request. Despite intensive research, especially in the area of business processes, web services and grids, an open and valid question is still how to manage service compositions in order to satisfy both functional and non-functional requirements as well as adapt to dynamic changes. This article describes an approach towards adaptive management of QoS aware service compositions. This approach integrates well known concepts and techniques and proposes various execution strategies based on dynamic selection and negotiation of services included in a service composition, contracting based on service level agreements, service enactment with flexible support for exception handling, monitoring of service level objectives, and profiling of execution data. An important element of the approach is an open architecture for adaptive service composition management. Its first prototypical implementation has been developed within an EU-funded Adaptive Service Grid project.

Abstract: Due to a rising interest in empirical ‘respect’ research but at the same time a somewhat fuzzy use of the term and its semantically close neighbors, we introduce a conceptual framework. The framework draws on existing philosophical traditions and empirical psychological works alike. It is pointed out that respect, acceptance, and tolerance are all attitudes of a subject towards an object which are not aligned on one dimension, but are concerned with quite different issues. Moreover, we propose that research needs to differentiate between two very different kinds of respect. Whereas appraisal respect, acceptance, and tolerance are attitudinal reflections of a subject’s decisions on certain issues (i.e., on influence, membership, and presence), recognition respect is proposed to be an overarching processing mode, i.e., a general attitude on how to confront others.

Abstract: The consumer electronics industry is a $240 billion global industry with a small number of highly competitive global players. We describe many of the risks associated with any global supply chain in this industry. As illustration, we also list steps that Samsung Electronics and its subsidiary, Samsung Electronics UK, have taken to mitigate these risks. Our description of the risks and illustration of mitigation efforts provides the backdrop to identify areas of future research.
Albers, Sönke and Michel Clement (2007): Analyzing the success drivers of e-business companies, IEEE Transactions on Engineering Management, 54 (2): 301-314.
Abstract: Although there is a growing amount of theoretical literature, only limited attention has been allocated to empirically determine the relative influence of a broad set of strategic success factors of e-business companies across several industries. We concentrate on the impact of marketing strategies and chosen business models and differentiate between direct and indirect drivers on revenue and profitability in order to estimate the total effect of a certain strategy or business model. Based on a survey of 147 e-businesses from different industries we empirically test, with the help of seemingly unrelated regression models, the relative importance of the various strategy elements. Our estimation results show that business models where the firm profits from transactions (e.g., via fixed access or usage fees) and is able to sell pricy products and services are well suited to reach profitability. The by far most important element of the marketing strategy is the achieved customer satisfaction, which has a significant and strong effect on revenue, but only a moderate direct effect on profitability. Due to our modeling approach we find that the total elasticity of this element of the marketing strategy is driven by the indirect effect from revenue on profitability
