چکیده

We consider the problem of dynamically allocating tasks to multiple agents under time window constraints and task completion uncertainty. Our objective is minimize number unsuccessful at end operation horizon. present a multi-robot allocation algorithm that decouples key computational challenges sequential decision-making uncertainty multi-agent coordination, addresses them in hierarchical manner. The lower layer computes policies for individual using dynamic programming with tree search, upper resolves conflicts plans obtain valid allocation. algorithm, Stochastic Conflict-Based Allocation (SCoBA), optimal expectation complete some reasonable assumptions. In practice, SCoBA computationally efficient enough interleave planning execution online. On metric successful completion, consistently outperforms baseline methods shows strong competitive performance against an oracle lookahead. It also scales well agents. validate our results over wide range simulations on two distinct domains: multi-arm conveyor belt pick-and-place multi-drone delivery dispatch city.

Dynamic multi-agent task allocation with spatial and temporal constraints

Realistic multi-agent team applications often feature dynamic environments with soft deadlines that penalize late execution of tasks. This puts a premium on quickly allocating tasks to agents, but finding the optimal allocation is NP-hard due to temporal and spatial constraints that require tasks to be executed sequentially by agents. We propose FMC TA, a novel task allocation algorithm that al...

Multi-Robot Allocation of Tasks with Temporal and Ordering Constraints

Task allocation is ubiquitous in computer science and robotics, yet some problems have received limited attention in the computer science and AI community. Specifically, we will focus on multi-robot task allocation problems when tasks have time windows or ordering constraints. We will outline the main lines of research and open problems.

Multi-Robot Task Allocation in the Light of Uncertainty

We describe an empirical study that sought general guidelines for task allocation strategies in multi-robot systems. We identify four distinct task allocation strategies, and demonstrate them in two versions of the multi-robot emergency handling task. We describe an experimental setup to compare results obtained from a simulated grid world to the results from real world experiments. Data result...

Multi-Robot Auctions for Allocation of Tasks with Temporal Constraints

We propose an auction algorithm to allocate tasks that have temporal constraints to cooperative robots. Temporal constraints are expressed as time windows, within which a task must be executed. There are no restrictions on the time windows, which are allowed to overlap. Robots model their temporal constraints using a simple temporal network, enabling them to maintain consistent schedules. When ...

Complex Tasks Allocation for Multi Robot Teams under Communication Constraints

The Multirobot Task Allocation (MRTA) paradigm is widely used in multirobot cooperation schemes, e.g. for observation, surveillance and tracking missions. Market-based approaches have yielded effective distributed solutions for such missions, showing the ability to manage heterogeneous, dynamic and robust robot teams. Two major challenges remain however poorly tackled: the management of inter-r...
