Basic distinctions/definitions
Researchers studying organizations and firms using computer simulations utilize a variety of basic distinctions and definitions that are common in computational science
* Agent-based vs Equation-based:
agent-based model
An agent-based model (ABM) is a computational model for simulating the actions and interactions of autonomous agents (both individual or collective entities such as organizations or groups) in order to understand the behavior of a system and what ...
s unfold according to the interactions of relatively simple actions, while equation-based models unfold numerically based on a variety of dynamic or steady-state equations (Note: some argue this is something of a false distinction since some agent based models use equations to direct the behavior of their agents)
* Model: simplified versions of the real world that contain only essential elements of theoretical interest
* Complexity of the model: the number of conceptual parts in the model and the connections between those parts
[Simon 1969]
* Deterministic vs. Stochastic: deterministic models unfold exactly as specified by some pre-specified logic, while stochastic models depend on a variety of draws from probability distributions
* Optimizing vs. Descriptive: models with actors that either seek optimums (like the peaks in fitness landscapes) or do not
Methodological approaches
There are a variety of different methodological approaches in the area of computational simulation. These include but are not limited to the following. (Note: this list is not Mutually Exclusive nor Collectively Exhaustive, but tries to be fair to the dominant trends. For three different taxonomies see Carley 2001; Davis et al. 2007; Dooley 2002)
*Agent-based models: computational models investigating the interaction of multiple agents (many of the following approaches can be 'agent-based' as well)
*Cellular automata: models exploring multiple actors in physical space whose behavior is based on rules
*Dynamic network models: any model representing actors and non-actor entities (tasks, resources, locations, beliefs, etc.) as connected through relational links as in

Dynamic network analysis (DNA) is an emergent scientific field that brings together traditional social network analysis (SNA), link analysis (LA), social simulation and multi-agent systems (MAS) within network science and network theory. Dynamic ...

Early research
Early research in strategy and organizations using computational simulation concerned itself with either the macro-behavior of systems or specific organizational mechanisms. Highlights of early research included:
*Cohen, March, & Olsen's (1972) ''Garbage Can Model of Organizational Choice'' modeled organizations as a set of solutions seeking problems in a rather anarchic 'garbage can'-esque organization.
*March's (1991) study of ''Exploration and Exploitation in Organizational Learning'' utilized John Holland's (1975) basic explore/exploit distinction to show the value of slow learners in organizations.
*Nelson & Winter's (1982) ''Evolutionary theory of economic change'' used a simulation to show that an evolutionary model could produce the same sort of GDP / productivity numbers as neo-classical rational choice theorizing.
Later research
Later research using computational simulation flowered in the 1990s and beyond. Highlights include:
*Carroll & Harrison's (1998) model of organizational demography and culture
*Davis, Eisenhardt & Bingham's (2009) model of organization structure in unpredictable environments
*Gavetti, & Levinthal's (2000) model of cognitive and experiential search
*Levinthal's (1997) NK model of adaptation on rugged fitness landscapes
*Rivkin's (2000) study of strategic imitation
*Rudolph & Repenning's (2002) model of disastrous tipping points
*Sastry's (1997) model of punctuated organizational change
*Zott's (2003) model of strategic evolution and dynamic capabilities
