Decentralized control of cooperative and autonomous agents for solving the distributed resource allocation problem

This paper focuses on the decision-making mechanism of coordination protocol for a multi-agent system in collaborative, distributed environment requiring resource allocation solutions. The model of distributed collaboration network (DCN) for distributed resource allocation is developed. The use of monitored viability of each agent as a feedback for the agent's reflexivity and goal adjustment mechanisms during the coordination process is introduced. Question: Will (can) a multi-agent system, as a whole, achieve efficient resource allocations, when each agent makes independent decisions, adjusted by feedback of its own viability measure to maximize its own goal based on limited information about the entire system? To investigate this question, experiments were conducted by using the parallel simulator TIE/Protocol to model the DCN and multi-agent system behavior.

Fuzzy approach to the spatial games in the total market area

The paper presents a fuzzy approach to building up a model of spatial hierarchy based on spatial games. It is derived from the analytical model by Bogataj and Bogataj (Int. J. Prod. Econ. 71 (1–3) (2001) 277). The main strategic problems of a supply chain are connected with the question of location and capacity of individual activity cells to achieve the best supply chain coordination. The results of supply chain coordination between two activity cells on the plain originate from Girlich's research paper (Inventory Modelling, Lecture Notes of the International Postgraduate Summer School, Vol. 2, ISIR, Budapest-Protoroz, 1995, pp. 13–24) and have been later transformed in frequency space, using the methodology of input–output analysis, Laplace transforms and MRP developed at Linköping Institute of Technology by Grubbström and his research group. The analytical results developed by Bogataj and Bogataj (2001) are compared with the results achieved by fuzzy set approach. In our paper the problem is formulated as a non-constant sum game. In this case the total market area is constant and the conditions for lower central places are described for different positions of these central places in an urban hierarchy in the case of two-level production. The results of fuzzy approach in logistic games are compared with analytical results.     

Hydrodynamic aspects of venting for vessels containing viscous fluids

Nine depressurization experiments for vessels containing water, freon-114 and high viscosity fluids have been analyzed. These experiments were carried out at different plants and provide information about the dependence of the depressurization process on the size of the vessel, the type of vent installed, and the initial conditions. The differences of venting into the atmosphere or venting into a catch tank have been also examined. The accuracy of the two-phase flow model used for the analysis of these experiments has been demonstrated by comparisons with steady state data referring to co-current liquid/vapor flow as well as to batch type of flows, where the liquid phase is stagnant.

Managing integration and coordination in cross‐functional teams: an international study of Concurrent Engineering product development

This study is about the influence of integration and coordination of organisational mechanisms on the effectiveness of the process of product development by cross-functional teams. The sample consists of 50 cross-national Concurrent Engineering (CE) project teams, from companies in Australia, Canada, Denmark, Finland, UK, and USA, in the technology intensive industries of aerospace, automobile, chemical, computer, electronics, shipbuilding, and telecommunications. The study offers a diagnostic tool which measures the effectiveness of the Concurrent Engineering team's process in terms of the behaviours and attitudes of the engineering/R&D and manufacturing representatives on the product development team: (a) two-way communication, (b) overlapping problems-solving, (c) readiness to use uncertain and ambiguous information released by team counterparts for decision-making, and (d) readiness to release uncertain and ambiguous information to team counterparts. The findings of the study are that integration mechanisms, such as team-based rewards and job rotation, and coordination mechanisms, such as project structure and information technology, and project leader's management style, support an effective team process, and overcome the negative effect of geographic distance and time-difference in cross-national teams. In addition, there are interesting implications for organisational learning in the practice of Concurrent Engineering for product development, and of the implications of these findings for practice and future research.     

Organizational adaptation to interdependence shifts: The role of integrator structures

R esearch summary: We investigate how organizational adaptation to interdependence shifts is influenced by “integrators.” These are formally mandated managerial roles meant to promote coordination across specialized but interdependent organizational subunits, yet they do so without relying on formal authority. While much has been learned about how integrators promote steady‐state coordination within a known pattern of interdependence, less is known about their impact on organizational adaptation when the pattern of interdependence itself is unknown. We discuss mechanisms by which integrators may nonetheless aid organizational adaptation and learning processes in such situations, and test our hypotheses in the context of a regulatory change that affected the in vitro fertilization (IVF) clinics sector in the United Kingdom using a differences‐in‐differences design. M anagerial summary: Organizational structure can influence how an organization adapts to change. We investigate how a regulatory change in the provision of fertility treatments in the United Kingdom forced clinics to change their workflows, and whether the presence of integrator roles enabled clinics to adapt to these changes. It is well known that integrator roles in general are valuable in coordinating across specialized organizational units, but this research points to the surprising implication that their value may persist even when the workflow being coordinated changes suddenly, in ways that nobody necessarily comprehends. Our research highlights the fact that even in an intensively science‐based work context, the “technology of organizing” can have a significant role in shaping organizational performance.

Tying the pieces together: A normative framework for integrating sales and project operations

Synchronizing sales efforts with project operations, such that (1) there is a steady flow of work that can be completed in a non-chaotic project environment, (2) resources maintain high utilization, and (3) desired deliverables reach customers within the promised lead-time, is extremely difficult. This paper proposes a normative approach to uniting the sales process with project operations capacity by coordinating movement of potential customers through the sales funnel with the company's internal project capacity. It also addresses contingencies with respect to company throughput as a result of changes in managing the market, the sales funnel, and project operations, while taking into consideration variation in scheduling as well as in managing project task and duration uncertainty.
