    Mastering demand and supply uncertainty with combined product and process configuration

    The key challenge for mastering high uncertainty of both demand and supply is to attune products and business processes in the entire supply chain continuously to customer requirements. Product configurators have proven to be powerful tools for managing demand uncertainty. This paper assesses how configurators can be used for combined product and process configuration in order to support mastering high uncertainty of both supply and demand. It defines the dependence between product and process configuration in a typology of interdependencies. The addressed dependences go beyond the definition phase and also include the effects of unforeseen backend events during configuration and execution. Based on a case study in the Dutch flower industry, a conceptual architecture is proposed for coordination of these interdependencies and development strategies are identified
    Organizing information integration in agri-food: A method based on a service-oriented architecture and living lab approach

    Agri-food enterprises operate in a complex and dynamic environment. To meet increasing demands of consumers, government and business partners, enterprises continuously have to work on innovations of products, processes and ways of cooperation in agri-food supply chain networks (AFSCN). Hence, a development towards a more knowledge-based economy is needed. The Lisbon strategy, launched by the European Union, to attain this knowledge-based economy, has failed so far. This paper argues that information sharing and organizing ICT are main critical areas to overcome this deadlock. However, ICT development in AFSCN involves an information integration task that has to deal with technical and organizational requirements and starts with an existing installed base. Traditional software engineering approaches are inadequate to address these issues. This paper provides an overall method for analysis, design and implementation of information integration, taking technical as well as organizational development into account. The method was derived from experiences in a research and development program in the Dutch arable farming sector. A generic integration framework forms the backbone of the method to ensure systematic and sustainable ICT development. Business process management (BPM), in combination with reference information models, plays an important role. The technical architecture and infrastructure are based on a service-oriented architecture (SOA). Attention is paid to the organizational infrastructure that is needed to embed the results in the right context, so that they will be broadly supported and used. The method is divided into three phases: analysis, basic design and iterative implementation. Analysis of the current situation in AFSCN is supported by an information integration framework. The basic design is a first version of the generic integration framework. In the iterative implementation phase, pilot projects are guided by this basic design, which results in incremental growth of the framework. The pilot projects follow a Living Lab (LL) approach. LLs represent a user-centric, open innovation approach for sensing, prototyping, validating and refining complex solutions in multiple and evolving real life contexts. The method is illustrated by an application to the Dutch arable farming sector. It can be concluded that the contribution of the presented method lies in combining different methodologies into a design approach for information integration, based on a sound architecture. The presented method leads to ICT that follows the business processes in real life and thus enhances appropriate information sharing to support a knowledge-based economy
    Understanding Heterogeneous Preferences of Cooperative Members
    Kalogeras, N. ; Pennings, J.M.E. ; Lans, I.A. van der; Garcia, P. ; Dijk, G. van - \ 2009

    We study the heterogeneity in the preference structure of cooperative members. Using conjoint analysis the utility that members attach to intra-organizational and strategic attributes of their cooperative is elicited. Recognizing that members are not homogenous, a concomitant finitemixture regression model is employed to allow preferences to vary across different member segments. With data from 120 cooperative members, we find that most members demonstrate rather similar preferences for strategic attributes but differ with respect to the intraorganizational attributes of control and management. Members¿ preference structures are affected by business size and attitudes towards risk.
    Applications of labels to trace material flows in multi-echelon supply chains
    Jansen-Vullers, M.H. ; Wortmann, J.C. ; Beulens, A.J.M. - \ 2004

    Current developments in society requires increasing information on products at batch level. This holds especially true for the food industry. To be able to meet such requirements, data on the origin of products are an important factor, frequently including details of production conditions in preceding echelons. This paper discusses how code numbers, batches and particularly labels in multi-echelon supply chains can be applied to manage the enormous amount of detailed data which are vital to these usually complex supply chains. The research shows that the concept of labels is much more applicable than commonly understood. First, it enables efficient aggregation of data in complex supply networks. This is important to delimit the start and end of a network and in taking dynamic changes into account. Second, labels add value to the product. In business this concept is already known, e.g. as brand (Champagne, Parma ham) or as quality characteristics (environmentally kind, animal friendly). In information systems, however, application of the concept of a label is only marginally used. This puts too much emphasis on product data at batch level and it is a missed opportunity to contribute to a sound basis for guaranteed product quality
