This research develops a set of computer simulations to extract the logical implications of the PI's ecological theory of the competition of social groups for members over time. The theory argues that groups interact with each other through the population of individuals which flow into and out of these groupings. The population of individuals is characterized as a set of points whose locations are defined by sociodemographic dimensions. These dimensions form a "phase space" within which social forms grow, decline, and change their characteristics over time. The short term (10-15 years) implications of the theory have been successfully tested in populations of voluntary associations, of U.S. occupations, and of cultural forms. A set of computer simulation studies will allow the exploration of how social groups and other entities develop under a larger range of population parameters. The Group Action Simulation Program (GASP) examines the effects of variations in several important parameters governing the behavior of the theoretical model, including (1) the rates at which people enter and exit from organizations, (2) the force of homophily among individuals' network ties, and (3) the extent of competition among groups. Outcome variables to be studied include tie stability, group size, group age, group overlap, group dispersion, and the number of groups in the system. In addition, the project explores the conditions under which organizational populations stabilize or fail to stabilize under these varying behavioral parameters.

这项研究开发了一组计算机模拟，以随着时间的推移而对社会群体的社会群体竞争的生态理论提取逻辑含义。该理论认为，群体通过流入和脱离这些分组的个体人群相互互动。个体的人口的特征是一组点，其位置是由社会人口统计学维度定义的。这些维度形成了社会形式在其中增长，衰落和改变其特征的“相空间”。该理论的短期（10 - 15年）含义已在自愿关联，美国职业和文化形式的人群中成功进行了测试。一组计算机模拟研究将允许探索社会群体和其他实体在较大范围的人群参数下如何发展。小组行动模拟计划（GASP）研究了有关理论模型行为的几个重要参数中变化的影响，包括（1）人们从组织中进入和退出组织的速率，（2）个人网络纽带之间同质性的力量，以及（3）群体之间竞争的程度。要研究的结果变量包括绑带稳定性，小组规模，小组年龄，小组重叠，小组分散以及系统中的组数量。此外，该项目探讨了组织人群在这些不同行为参数下稳定或无法稳定的条件。
