Mobile robots should perform a growing number of tasks and react to time-critical events. Thus, the ability to interrupt a task and resume it later is crucial. While interleaved execution occurs often in robotics, existing approaches do not consider the fact that interrupting a task and resuming an interrupted task often requires intermediate steps. In this paper we present an approach to inter...

In this paper we address the problem of designing an interruptible system in a setting in which n problem instances, all equally important, must be solved. The system involves scheduling executions of contract algorithms (which offer a tradeoff between allowable computation time and quality of the solution) in m identical parallel processors. When an interruption occurs, the system must report ...

The paper discusses a layered design for a discrete event simulation framework based on the Beta programming language. A description of goals and motivation of simulation modelling is followed by a brief characterization of Beta and its suitability for work this area. After some general comments on the history and state of simulation programming the design of the BetaSIM framework is illustrate...

A multi-period model of interruptible electric power service that includes early notification may be described as a stochastic control problem: whom to notify when. When customer interruption losses are multiplicative or submodular, an optimal priority ordering exists, allowing for a simple notification policy.

In this paper, we present a new approach to synchronization in real-time systems. Existing methods for synchronization in real-time systems are pessimistic, and use blocking to enforce concurrency control. Protocols such as the priority ceiling protocol have been proposed to reduce the priority inversion that occurs when low priority tasks block high priority tasks. However, the priority ceilin...

abstract: In the present work, determining the optimal strategy(profit based) of multi virtual power plants (VPPs) as well as the objective of maximizing profit through the multi-level control of VPPs are discussed by the micro-grid utilization center including virtual power plants. VPPs include renewable resources such as wind farms, photovoltaic, and conventional resources such as fuel cell, ...

Traditional charging stations have a single function, which usually does not consider the construction of energy storage facilities, and it is difficult to promote consumption new energy. With gradual increase in number vehicles (NEVs), give full play complementary advantages source-load resources provide safe, efficient, economical supply services, this paper proposes optimal operation strateg...

In this paper, we present an analysis aiming at making task planning interruptible. A task planner represents a testbed for implementing interruption strategies. A control search in the space of partial has the property of representing one partial plan at a time only while being complete when not interrupted. A deenition of the quality of a partial plan is proposed, in addition to the statistic...
