A computational model of organizational adaptation in which change occurs at both the strategic and the operational level is presented. In this model, simulated annealing is used to alter the organization's structure even as the agents within the organization learn. Using this model a virtual experiment is run to generate hypotheses which can be tested in multiple venues. The results suggest that, although it may not be possible for organizations of complex adaptive agents to locate the optimal form, they can improve their performance by altering their structure. Moreover, organizations that most successfully adapt over time come to be larger, less dense, with fewer isolated agents, and fewer overlooked decision factors. These results have implications for organizations of both humans and non-humans. For example, they suggest that organizational learning resides not just in the minds of the personnel within the organization, but in the connections among personnel, and among personnel and tasks. These results suggest that collections of non-humans may come to seem more intelligent (i.e., show improved performance) even if the agents remain unchanged if the system simply develops duplicate copies of some of the artificial agents and if the connections among agents are dynamically altered.

    • "Several organizational Structures for modeling MASs are introduced in literature (Deloach and Matson, 2004), (Horling and Lesser, 2005), (Kolp, Giorgini, Mylopolos, 2006). In addition, a variety of adaptation methods for different organizations have been proposed yet (Carley, 1997), (Dignum et al. ,2004), (Ghijsen, Jansweijer, and Wielinga, 2009), (Ghijsen, Jansweijer, and Wielinga, 2008), (Kirn and Gasser, 1998), (Kota, Gibbins, Jennings, 2009), (Martin and Barak, 2006), (Rosenfeld, Kaminka, Kraus, Shehory, 2008), (Zheng-guang and Xiao-hui, 2006). All of these methods attempt to enhance the system effectiveness using adaptation. "

    ABSTRACT: Proper organizational modelling is a challenging issue in complex cooperative multi-agent systems. In this paper, we propose a team-based multi-agent organizational model, based on the Schwaninger's model of intelligent human organizations. It provides an integrative framework to rapid task handling, the main effectiveness requirement in many applications. Adaptation via reorganization makes the model suitable for dynamic, uncertain environments. Fast initial team formation, greedy capability-based coalition formation, and using the nearest neighbours' resources improve utility compared to the identified hierarchical organizational models.

    • "While organizational structure changes are made to adapt to the task environment change, task accomplishment and schedule are also affected by the change of organizational structure. Organizational adaptation has two different levels: strategic and operational [15], and furthermore it should involve more dimensions besides accomplishment ratio. "

    ABSTRACT: Agile enterprises with different organizational structures manifest different organizational behaviors when responding to environmental changes. In this paper, we use a computational model to examine organizational adaptation on four dimensions: Agility, Robustness, Resilience, and Survivability. We analyze the dynamics of organizational adaptation by a simulation study on the interaction between tasks and organization in a sales enterprise. The `what if' analyses in different scenarios show that more flexible communication between employees and less hierarchy level with the suitable centralization can improve organizational adaptation. The developed simulation model supports the exploration of the parametric space that defines alternative organizing processes for the optimal strategy given the specified environmental dynamics.

    • "Research in the field of organizational theory has shown that when an organization is able to adapt its structure, it will be able to operate more efficiently and effectively [2]. Two main types of reorganization can be distinguished; changing the coordination strategy in the organization and changing relations and interaction patterns between agents. "

    ABSTRACT: Research on organization of Multiagent Systems (M.A.S.) has shown that by adapting its organization, a M.A.S. is better able to operate in dynamic environments. In this paper we describe an experiment with a M.A.S. that consists of agents where the capability to reorganize is integrated in their coordination mechanism. In the RoboCupRescue simulator we have implemented a M.A.S. where work can be coordinated according to three different coordination styles; direct supervision and standardization of skills with and without a reorganization extension. An experiment shows the effects of unknown workload distribution and incomplete information on the performance of the three styles. Results show significant interaction effects between both workload distribution and coordination mechanism, and completeness of information and coordination mechanism. Furthermore, results show that standardization of skills with reorganization performs better and is more robust to heterogeneous workload distribution and incompleteness of information.
