Minimum-Cost Offloading for Collaborative Task Execution of MEC-Assisted Platooning

In this paper, we study the offloading decision of collaborative task execution between platoon and Mobile Edge Computing (MEC) server. The mobile application is represented by a series of fine-grained tasks that form a linear topology, each of which is either executed on a local vehicle, offloaded to other members of the platoon, or offloaded to a MEC server. The objective of the design is to minimize the cost of tasks offloading and meets the deadline of tasks execution. The cost minimized task decision problem is transformed into the shortest path problem, which is limited by the deadline of the tasks on a directed acyclic graph. The classical Lagrangian Relaxation-based Aggregated Cost (LARAC) algorithm is adopted to solve the problem approximately. Numerical analysis shows that the scheduling method of the tasks decision can be well applied to the platoon scenario and execute the tasks in cooperation with the MEC server. In addition, compared with task local execution, platoon execution and MEC server execution, the optimal offloading decision for collaborative task execution can significantly reduce the cost of task execution and meet deadlines.

Agent-Based Modeling and Simulation of Intelligent Distributed Scheduling Systems

For responsiveness and agility, disruptive events must be managed locally to avoid propagating the effects along the value chain. In this work, a novel approach based on emergent distributed scheduling is proposed to overcome the traditional separation between task scheduling and execution control. An interaction mechanism designed around the concept of order and resource agents acting as autonomic managers is described. The proposed Manufacturing Execution System (MES) for simultaneous distributed (re)scheduling and local execution control is able to reject disturbances and successfully handle unforeseen events by autonomic agents implementing the monitor-analyze-plan-execution loop while achieving their corresponding goals. For detailed design of the autonomic MES and verification of its emergent behaviors, a goal-oriented methodology for designing interactions is proposed. Encouraging results obtained for different operating scenarios using a generative simulation model of the interaction mechanism implemented in Netlogo are presented.

PERJANJIAN BUILD AND TRANSFER ANTARA PEMERINTAH DAERAH DENGAN PIHAK SWASTA DALAM PENYEDIAAN INFRASTRUKTUR (Studi Di Nusa Tenggara Barat)

Undergoing local authority does not always bring with it advantage to the local government, but this may challenge the local government to make efforts to support and fund its governmental develop-ment. On of the ways out is by working in cooperation with private enterprises based the law of local execution. This study is intended to analize the cooperative agreement of local government with build and transfer model which is adopted widely by some local governments in Indonesia. Through normative juridical study along with statute and case approaches, it is found the coopera-tive agreement of build and transfer in Indonesia is ruled by some official regulations which have different substantive points and have conflicted norms and vague rules related to legal subyect, procedures or mechanism of having agreement. In the future it is needed to issue legal decision re-lated to cooperative agreement between the local government and private enterprises which is more comprehensively in order to resolve the legal affairs or disputes. Key words: build and transfer, infrastructure, bouwheer

Competitive Coevolutionary Learning of Fuzzy Systems for Job Exchange in Computational Grids

In our work, we address the problem of workload distribution within a computational grid. In this scenario, users submit jobs to local high performance computing (HPC) systems which are, in turn, interconnected such that the exchange of jobs to other sites becomes possible. Providers are able to avoid local execution of jobs by offering them to other HPC sites. In our implementation, this distribution decision is made by a fuzzy system controller whose parameters can be adjusted to establish different exchange behaviors. In such a system, it is essential that HPC sites can only benefit if the workload is equitably (not necessarily equally) portioned among all participants. However, each site egoistically strives only for the minimization of its own jobs' response times regularly at the expense of other sites. This scenario is particularly suited for the application of a competitive coevolutionary algorithm: the fuzzy systems of the participating HPC sites are modeled as species that evolve in different populations while having to compete within the commonly shared ecosystem. Using real workload traces and grid setups, we show that opportunistic cooperation leads to significant improvements for each HPC site as well as for the overall system.
