Inter-organizational communication, coordination, and network effectiveness have long been of great interest. However, the level of their complexity and situational dependencies still create challenges for researchers and public managers. It is usually assumed that inter-organizational communication leads to inter-organizational coordination, but little is known how these processes interact and complement each other. This article aims at identifying relationships linking these processes and analyzing their impact on effectiveness of emergency management networks. Achieving the goal of the article based on the survey questionnaire conducted with 83 experts. The results were analyzed using the principal components analysis (PCA), correlation analysis, hierarchical clustering, and partial least-square path modeling (PLS-PM). The analyses conducted allow for identifying the dimensions of the research processes, and relationships linking them. This was the basis for building the research models testing how relationships between inter-organizational communication and coordination influence the effectiveness of emergency management networks. Comparing analyzed models points to complementarity, parallelism, and the possibility of a non-sequential course of inter-organizational communication and coordination.

In order to study processes in organizations which are result of many local interactions between organization's actors, more and more often computer simulations are used. One of the problematic issue in this kind of studies is to ensure that the outcomes of the models reflect in some way real-world social networks. In this article we compare network structures generated in two such models using as indicators the distribution of the number of contacts, the average path length between two nodes and the clustering coefficient.

In this work we examine the impact of informal contacts network in the context of organizational change. We use a cellular automata model with majority rule and movement but supplemented with additional mechanism which generates much more unbalanced network between agents. The structures of the emerged networks are briefly described and the outcomes of two variants of simulation experiments are presented. The main results are that the presence of informal contacts network leads to (1) stronger effects when the two groups of agents (those in favor of the change, and those against it) are not equal and (2) to more unpredictable outcome for large density of agents.

The article is an attempt to apply complexity theory to study organizations in an environment filled with their competitors and complementors. An agent-based simulation is used to analyze effects of interactions in an environment with different level of complexity. Agents operate trying to adapt to fitness landscape they are placed in (which is based on Kauffman's NK model) and the obtained level of competition is observed. Results of conducted simulations are presented and analyzed.

The article presents an example of an extension of multiagent influence diagram (MAID) proposed by Koller and Milch with some concepts derived from sequential influence diagram (SID) described by Jensen, Nielsen and Shenoy. Its main aim is to test if these two graphical languages can be merge in order to deal with an asymmetric multi-agent scenario. An example of such a scenario is given and it is modeled and solved using techniques derived from these two languages. The obtained solution is verified using traditional game-theoretic method.
