In this work we consider the problem of multiagent planning under sensing and acting uncertainty with a one time-step delay in communication. We adopt decentralized partially observable Markov processes (Dec-POMDPs) as our planning framework. When instantaneous and noise-free communication is available, agents can instantly share local observations. This effectively reduces the decentralized pl...

|We propose a distributed and optimal motion planning algorithm for multiple robots. The computationally expensive problem is decomposed into two modules { path planning and velocity planning. The D search method is applied in both modules, based on either geometric formulation or schedule formulation. Optimization is achieved at the individual robot level by de ning cost functions to minimize,...

the proliferation of information and communications technology (ict) along with the incremental growth in the use of cloud services, enterprise network and data center technologies in recent years, have caused unprecedented expansion of computer networks. however, the existing network architecture was not well designed to meet the requirements of today's needs. one of the most important pr...

Efficient logistics systems move essential medicines down the supply chain to the service delivery point, and then to the end user. Experts on logistics systems tend to see the supply chain as requiring centralized control to be most effective. However, many health reforms have involved decentralization, which experts fear has disrupted the supply chain and made systems less effective. There is...

this paper deals with the problem of user-server assignment in online social network systems. online social network applications such as facebook, twitter, or instagram are built on an infrastructure of servers that enables them to communicate with each other. a key factor that determines the facility of communication between the users and the servers is the expected transmission time (ett). a ...

This paper seeks to address the role of European public policy in addressing problem Covid-19 vaccine-rollout policy. Currently Europe, instead market-based allocation a centralized command-based approach has been implemented essential questions production and distribution vaccines throughout EU. is centralized, decision-making on which leading political sociological tensions among EU Member St...

Centralized methods of planning the use N devices for realization operations on a set M objects with scheme elementary operation is "one object  k devices" are proposed. Methods include modifications following cases: 1) only described applied ("rigid" requirement); 2) named preferred, but there possible options reducing specified (desired) maximum number individual ("soft" requirement). suitab...

In this paper we propose a methodology for coordinating a group of mobile robots that go through predefined paths in a dynamic industrial environment. The technique is developed to be implemented into a real industrial framework. Coordination diagrams are used for representing the possible collisions among the vehicles. We exploit this information for developing a centralized and incremental pl...

Drawings alone are no longer a sufficient format to manage complex project data. To establish a competitive advantage in a very competitive industry, engineers, planners and designers must embrace the benefits of enterprise wide project data sets. This paper presents an approach that transforms the traditional engineering design project lifecycle by synthesizing drawing data, planning applicati...
