Developing a Production Structure Model using Service-Dominant Logic – A hypergraph-based Modeling Approach

2019-07-26 , Li, Mahei , Peters, Christoph , Leimeister, Jan Marco

To make a fundamental shift towards value orientation, manufacturing companies strategically move to integrate services into their portfolio. While manufacturing firms rely on production information systems as the backbone of their operations, these systems are based on product structure models (e.g., bill of materials). This poses a problem because services do not adhere to the goods-dominant perspective of product structures. To solve this divide, this paper proposes an integrative mathematical model for both production systems and service systems. This model draws upon concepts of service-dominant logic and is based on hypergraph theory. To illustrate that the production structure model includes both product structures and process structures, we further demonstrate that the production structure model can be transformed into either. Therefore, our theoretical contribution lies in introducing a structural model for production systems that is compatible with structures of a service system model. For practice, this model enables the development of production information systems that can plan and control products, services and hybrids.

A Hypergraph-based Modeling Approach for Service Systems

2018 , Li, Mahei Manhai , Peters, Christoph , Leimeister, Jan Marco

Currently, research on service science has emerged as its own discipline, where service systems are its basic unit of analysis. However, without a clearly defined modeling approach for service systems, analyzing a service system is challenging. We therefore propose a conceptual hypergraph-based modeling approach, which can be used to model services for both traditional goods-dominant businesses, as well as service-businesses. We define key elements of a service system while drawing upon hypergraph theory and present three modeling properties which are required to model a service systems graph (SSG). The focus of SSGs is to describe the relationships between the various resources, actors and activities, thus configuring a service system. It provides the foundation for computer graphic simulations and database applications of service business structure for future research.

Towards Bridging the Gap between Business Model Innovation and Practice Using Hypergraph-based Modeling

2018 , Li, Mahei , Peters, Christoph , Ernst, Sissy-Josefina , Leimeister, Jan Marco

A hypergraph-based modeling of businesses bridges the gap between business model innovations and its implementation into enterprise solutions. By formalizing resources, actors, activities (processes) and functions into one model, their relationships are clearly defined, while encompassing both the data and processual structure. A database-based graphical tool supports system analysts and decision makers to structure and analyze their business model and corresponding value proposition. This model can thus be used for future implementations.
