    Clustering the imp thought: searching roots and diversities in imp research2018Conference paper (Refereed)
    Abstract [en]

    IMP research is often treated as an empirical perspective describing complexities of repeated business-to-business exchanges and their embeddedness. While building on some common understandings and concepts, this paper asks: How homogeneous is the IMP research? This paper uses cluster analysis to capture the roots and various sub-groups of IMP research as means to depict the question of homogeneity (i.e. a core focus in the research) or heterogeneity (i.e. using references from other fields or specific to sub-fields) of the IMP thought. In this scientific work in progress paper we introduce how we design to use bibliographical methods in order to harvest data from an extensive amount of IMP-related articles written from the 1970’s onwards. In this first attempt to reveal IMP we used overall 294 articles yielded to 10,615 co-citation relationships. A threshold of minimum number of citations of a cited reference was set to five (5) to capture such references that have been cited in multiple publications. We introduce visual mapping of defined subject area clusters and as an example we describe shortly clusters. Perhaps not surprisingly our findings suggest that IMP research is not so homogenous, with at least four clear clusters of IMP-research each utilizing different key references.

    Vehicle routing scheduling problem with cross docking and split deliveries2014In: Computers and Chemical Engineering, ISSN 0098-1354, E-ISSN 1873-4375, Vol. 69, p. 98-107Article in journal (Refereed)
    Abstract [en]

    One of the most important issues in managing a supply chain which makes the materials flow more efficiently from suppliers to customers is cross docking. In this paper a vehicle routing and scheduling problem in a network consisting of suppliers, customers and a cross dock is considered. A set of homogenous vehicles transfer products from suppliers to customers through a cross dock. Each vehicle has a limited capacity and both suppliers and customers must be visited within their time windows, also a customer can be visited more than once by different vehicles. A mixed integer non linear mathematical formulation of this problem is provided. A simulated annealing and a hybrid metaheuristic algorithm combining ant colony system and simulated annealing are proposed. These two proposed metaheuristics are implemented on different data sets. The experimental results show the superior performance of the hybrid algorithm compared with the proposed simulated annealing algorithm.

    Investigating the Cannibalizing Effect in a Two-Market Situation Using Agent-Based Simulation2018Conference paper (Refereed)
    Abstract [en]

    This paper explores the potential cannibalizing effects of introducing a flexible auction marketto the traditionally established market based on long-term contracts. By means of agent-based modellingand simulation based on an empirical case of a railway logistics service provider, we investigate thepotential effects of this new market on previously established customer contracts.

    Role and Position Dynamics in Business Networks: Using an Agent-Based Model to Simulate the Impact of a New Market Solution on a Focal Actor’s Role and Position2018Conference paper (Refereed)
    Abstract [en]

    This paper explores the dynamics involved in the role and position transition of a focal actor in a business network as a result of introduction of a new business solution by that focal firm. Having two main classes of customer relationships due to the new business solution, the paper illustrates how the dynamics involved in the customers’ interactions can have consequences for the firm’s role and position in the network. An agent-based model based on an empirical case of a transport service provider is presented. Using agent-based simulation, the paper investigates the role/position change processes of the firm after the adoption of an online auction system. The paper illustrates how the market compositions including micro specifications of customers affect the interaction outcomes of the customers in the auction market at a macro level and hence different roles/positions emerge for the focal actor.
