Recycling has been gaining ground, thanks to the recent progress made in the related technology. However, a limiting factor to its wide adoption, is the lack of modern tools for managing the collection of recyclable resources. In this paper, we present EcoTruck, a management system for the collection of recyclable paper products. EcoTruck is modelled as a multi-agent system and its implementation employs Erlang, a distribution-oriented declarative language. the system aims to automate communication and cooperation of parties involved in the collection process, as well as optimise vehicle routing. the latter have the effect of minimising vehicle travel distances and subsequently lowering transportation costs. By speeding up the overall recycling process, the system could increase the service throughput, eventually introducing recycling methods to a larger audience.

this paper considers the analysis and constrained control problems of positive systems with time-varying delays. A system is a called positive system if its states keep nonnegative whenever its initial conditions and inputs are nonnegative, and the control is under positivity constraint means that the resulting closed-loop system is not only stable, but also positive. the main contribution lies in the following aspects. Firstly, based on a linear copositive Lyapunov-Krasovskii functional, some stability criteria are established for positive systems with time-varying delays. Secondly, constrained controller for a class of systems with time-varying delays is designed, which guarantees the corresponding closed-loop system is positive and asymptotically stable.

this paper is concerned with event refinement in the context of CSP parallel to B. Our motivation to include this notion within the CSP parallel to B framework is the desire to increase flexibility in the refinement process. this approach provides the ability to change the events of CSP processes and B machines when refining a system. Notions of refinement based on traces and on traces/divergences allow abstract events to be refined by sequences of concrete events. A complementary notion of refinement between B machines is also proposed, yielding compositionality results for refinement of CSP parallel to B controlled components. the paper also introduces a notion of I/O refinement into our event refinement framework.
