This thesis explores a method for multiple suppliers to coordinate resource scheduling of task requests from multiple consumers using decentralized planning. A time window is associated with each task and some tasks require simultaneous servicing from multiple resources of specified classes to fulfil a request. The suppliers create schedules for their resources that maximize the value of all tasks fulfilled, while minimizing travel cost, and respecting all time window constraints. This thesis presents Infeasibility Cooling Adaptive Allocation for Resource United Scheduling (ICAARUS), a novel Adaptive Large Neighborhood Search (ALNS) algorithm that is capable of synchronizing tasks across a variable number of resources. A supplier's individual schedule and cost function is kept private from consumers. An e-commerce style of multi-round bidding is introduced to notify suppliers of resource request parameters and to allow consumers to synchronize resources from independent suppliers. A Mixed-Integer Linear Program (MILP) is used by the consumer to select the least costly bids that can be combined to fulfill a task's requirements.
