Abstract: Event-B is a well known methodology for the verified design and development of systems that can be characterised as discrete transition systems.Hybrid Event-B is a conservative extension that interleaves the discrete transitions of Event-B (assumed to be temporally isolated) with episodes of continuously varying state change.While a single Hybrid Event-B machine is sufficient for applications with a single locus of control, it will not do for autonomous systems, which have several loci of control by default.Multi-machine Hybrid Event-B is designed to allow the specification of systems with several loci of control.The formalism is succinctly surveyed, pointing out the subtle semantic issues involved.The multi-machine formalism is then used to specify a relatively simple incident response system, involving a controller, two drones and three responders, working in a partly coordinated and partly independent fashion to manage a putative hazardous scenario.
