The article deals with study оf the criteria, parameters and performance indicators for the implementation of the collective mission of extended space monitoring by a group that includes control objects with different functionality. The most urgent military-technical task of recent times – monitoring of extended spaces- is considered as an example of a mission. A feature of the article is the assumption about of hazardous zones in the monitoring area. Any counteraction from potentially critical objects may significantly limit the capabilities and even disable the monitoring tools. This proviso affects for implementation of the mission by the group and leads to a revision of the group collective strategies and individual strategies for monitoring tools, their movement routes, and decision-making algorithms and etc. Monitoring tools are modeled as intelligent agents trained by the "collectivism" paradigm. It provides a common resource of situational awareness of the group, the organization of negotiations between agents and mutual assistance to each other in the event of problem situations. A general approach has been developed to evaluate the effectiveness of solving collective problems by a heterogeneous group of agents, taking into account the objective function, resource intensity of the entire mission and organizing active interaction between agents. It is proposed that the mission efficiency characteristic expressed as a weighted sum of the normalized indicators of the parameters of the agents' functions with the weights "significance of the function for the mission" and "value of the object". It is shown that the loss of efficiency in the performance of a collective mission in the event of problematic situations with an agent (active enemy action, breakdown, lack of the necessary functionality, resources, etc.) can be compensated by the required functionality of other agents of the group with the appropriate reconfiguration of tasks.
