TL;DR: In this article, the authors present a system and method for managing a telecommunications network that employs a network management architecture that provides an overlay in which network management functions are performed, including a workstation function that provides a graphical user interface (GUI) for a user to interact with an object model of the physical telecommunications network.
Abstract: A system and method for managing a telecommunications network. The system and method employs a network management architecture that provides an overlay in which network management functions are performed. The network management architecture includes a workstation function that provides a graphical user interface (GUI) for a user to interact with an object model of the physical telecommunications network, a telecommunications network management subsystem that provides an object model of the network including object models of network equipment and connectivity between the equipment, a database subsystem that stores "current" and "future" views of the network, and an object request broker that translates objects from a first object-oriented paradigm to a second object-oriented paradigm for use by the GUI. The network management architecture facilitates network design by determining network performance metrics. The network architecture can also be used to assess the performance of a given network configuration by virtue of simulation. The network architecture can also be used to initialize switchover logic for network restoration.

TL;DR: A global review of the crucial strategic and tactical steps of transit planning: the design and scheduling of the network and a classification of 69 approaches dealing with the design, frequencies setting, timetabling of transit lines and their combinations is proposed.
Abstract: This paper presents a global review of the crucial strategic and tactical steps of transit planning: the design and scheduling of the network. These steps influence directly the quality of service through coverage and directness concerns but also the economic profitability of the system since operational costs are highly dependent on the network structure. We first exhibit the context and the goals of strategic and tactical transit planning. We then establish a terminology proposal in order to name sub-problems and thereby structure the review. Then, we propose a classification of 69 approaches dealing with the design, frequencies setting, timetabling of transit lines and their combinations. We provide a descriptive analysis of each work so as to highlight their main characteristics in the frame of a two-fold classification referencing both the problem tackled and the solution method used. Finally, we expose recent context evolutions and identify some trends for future research. This paper aims to contribute to unification of the field and constitutes a useful complement to the few existing reviews.

TL;DR: It is shown that through a strategy of pre-failure cross-connection between the spare links of a mesh network, it is possible to achieve 100% restoration with little, if any, additional spare capacity than in aMesh network.
Abstract: Cycle-oriented preconfiguration of spare capacity is a new idea for the design and operation of mesh-restorable networks. It offers a sought-after goal: to retain the capacity-efficiency of a mesh-restorable network, while approaching the speed of line-switched self-healing rings. We show that through a strategy of pre-failure cross-connection between the spare links of a mesh network, it is possible to achieve 100% restoration with little, if any, additional spare capacity than in a mesh network. In addition, we find that this strategy requires the operation of only two cross-connections per restoration path. Although spares are connected into cycles, the method is different than self-healing rings because each preconfigured cycle contributes to the restoration of more failure scenarios than can a ring. Additionally, two restoration paths may be obtained from each pre-formed cycle, whereas a ring only yields one restoration path for each failure it addresses. We give an optimal design formulation and results for preconfiguration of spare capacity and describe a distributed self-organizing protocol through which a network can continually approximate the optimal preconfiguration state.

TL;DR: The results show that the proposed multi-objective optimization model can be applied as an effective tool in the strategic planning for green supply chain and the sensitivity analysis provides some interesting managerial insights for firms.
Abstract: In this paper, we study a supply chain network design problem with environmental concerns. We are interested in the environmental investments decisions in the design phase and propose a multi-objective optimization model that captures the trade-off between the total cost and the environment influence. We conduct a comprehensive set of numerical experiments. The results show that our model can be applied as an effective tool in the strategic planning for green supply chain. Meanwhile, the sensitivity analysis provides some interesting managerial insights for firms.
