From supply chains to demand networks. Agents in retailing: the electrical bazaar
A paradigm shift is taking place in logistics. The focus is changing from operational effectiveness to adaptation. Supply Chains will develop into networks that will adapt to consumer demand in almost real time. Time to market, capacity of adaptation and enrichment of customer experience seem to be the key elements of this new paradigm. In this environment emerging technologies like RFID (Radio Frequency ID), Intelligent Products and the Internet, are triggering a reconsideration of methods, procedures and goals. We present a Multiagent System framework specialized in retail that addresses these changes with the use of rational agents and takes advantages of the new market opportunities. Like in an old bazaar, agents able to learn, cooperate, take advantage of gossip and distinguish between collaborators and competitors, have the ability to adapt, learn and react to a changing environment better than any other structure. Keywords: Supply Chains, Distributed Artificial Intelligence, Multiagent System.Postprint (published version

A survey of simulation techniques in commerce and defence
Despite the developments in Modelling and Simulation (M&S) tools and techniques over the past years, there has been a gap in the M&S research and practice in healthcare on developing a toolkit to assist the modellers and simulation practitioners with selecting an appropriate set of techniques. This study is a preliminary step towards this goal. This paper presents some results from a systematic literature survey on applications of M&S in the commerce and defence domains that could inspire some improvements in the healthcare. Interim results show that in the commercial sector Discrete-Event Simulation (DES) has been the most widely used technique with System Dynamics (SD) in second place. However in the defence sector, SD has gained relatively more attention. SD has been found quite useful for qualitative and soft factors analysis. From both the surveys it becomes clear that there is a growing trend towards using hybrid M&S approaches
Inter Organizational Relationships Performance in Third Party Logistics: conceptual framework and case study
Supplier relationship management is an important challenge for shippers in logistics outsourcing. This paper attempts to understand the factors which affect inter organizational relationships performance in third party logistics and proposes a conceptual framework specifically for inter organizational relationship performance in third party logistics. We also draw a set of propositions from published research and exploratory inter-views with practitioners to explain inter organizational relationships performance in third party logistic net-works. Five main dimensions of inter organizational relationships are identified which affect performance in third party logistics: commitment, supplier adaptation, conflict resolution, partner fit and communication. In order to assess the validity of our conceptual model we include a case study in this paper. The case study is based on Shell Chemicals Europe and their portfolio of seventeen third party logistic service suppliers
institutional innovation from the bottom up?
A sustainable economy fulfills societal needs in a fundamentally different
way to the current economic system. Improvements to the efficiency of
existing technologies or practices appear insufficient for achieving
sustainable development within the planetary boundaries. Disruptive,
systemic and transformational changes appear necessary in order to replace
existing technologies and practices to establish a sustainable economy.
Such innovations often start out in niches; however, the scaling up and
the ultimate replacement of current socio-technical systems requires
governance to allow for the coordination of actors, the reorganization of
socio-technical systems and the mobilization and allocation of resources.
As governmental institutions are part of the current (non-sustainable)
systems and thereby fail to provide coherent, integrated and transformative
governance, we explore whether institutional innovation from non-state
actors can step in to provide governance of transformation processes.
Based on explorative qualitative case studies of networks in the food sector,
city planning and reporting tools, we analyze the potential of bottom-up
institutional innovations to coordinate actors in transformation processes
