TRACS is an established driver scheduling system [2, 3, 4, 6, 8, 9]. Its variant BusTRACS is being used by 29 bus companies, and TrainTRACS is being used by the train operator ScotRail. TrainTRACS has also been used in scheduling projects for several other train operators. As the transport operators start using the system, difficult problem issues arising from individual companies are carefully...

This paper presents a dynamic extra buses scheduling strategy to improve the transit service of transit routes. In this strategy, in order to decide when to dispatch an extra bus, the service reliability of transit route is assessed firstly. A model aimed at maximizing the benefit of the extra buses scheduling strategy is constructed to determine how many stops extra buses need to skip from the...

To achieve the promising potentials by using tremendous distributed resources, effective and efficient scheduling algorithms are fundamentally important. Scheduling such applications is challenging because target resources are heterogeneous, their load and availability varies dynamically. Previous parallel system was assumed to be organized with homogeneous platform and connected via memory, bu...

In this paper, we propose a fault-tolerant scheduling for realtime embedded systems. Our scheduling algorithm is dedicated to multibus heterogeneous architectures, which take as input a given system description and a given fault hypothesis. It is based on a data fragmentation and passive redundancy, which allow fast fault detection/retransmission and efficient use of buses. Our scheduling appro...

Smart distribution networks (SDNs) plays a significant role in future power networks. Accordingly, the optimal scheduling of such networks, which include planning of consumers and production sections, inconsiderably concerned in recent research studies. In this paper, the optimal planning of energy and reserve of SDNs has been studied. Technical constraints of distribution network and power gen...

Consider the problem of scheduling sporadic messages with deadlines on a wireless channel. We propose a collision-free medium access control (MAC) protocol which implements static-priority scheduling and present a schedulability analysis technique for the protocol. The MAC protocol allows multiple masters and is fully distributed; it is an adaptation to a wireless channel of the dominance proto...

Power system planning and operation in present day are more in favour of economic factors and less in terms of technical aspects such as: system security, reliability and stability analysis. Case in point being: the generator scheduling or the pattern in load sharing among the various generators forms a major part in power system planning. Scheduling primarily based on economic criteria, essent...

Controller Area Network is normally used in eventtriggered communication systems. These are known for not supporting composability with respect to the system temporal behavior. When using a time-triggered communication paradigm, such composability is achieved. However, common time-triggered systems rely on static message scheduling which compromises system flexibility. In this paper the authors...

Partitioned register-set architectures pose a challenge to standard scheduling algorithms. To create an efficient schedule, an instruction scheduler for such an architecture must consider the location of an operand in the register file, the availability of the intercluster data bus, and the profitability of a inter-cluster copy instruction. This technical report presents the implementation of J...

We present a new model for a strategic locomotive scheduling problem arising at the Deutsche Bahn AG. The model is based on a multi-commodity min-cost flow formulation that is also used for public bus scheduling problems. However, several new aspects have to be additionally taken into account, such as cyclic departures of the trains, time windows on starting and arrival times, network-load depe...
