Abstract:
The aim of this paper is to present the suitability of three different global optimization methods for specifically the exact optimum solution of the nonlinear transportation problem (NTP). The evaluated global optimization methods include the branch and reduce method, the branch and cut method and the combination of global and local search strategies. The considered global optimization methods were applied to solve NTPs with reference to literature. NTPs were formulated as nonlinear programming (NLP) optimization problems. The obtained optimal results were compared with those got from literature. A comparative evaluation of global optimization methods is presented at the end of the paper to show their suitability for solving NTPs.

The question of efficiency of transport systems is one of the actual questions of present time. Performing the duty from moving loads and providing the various blessing for an economy and population, transport become a source of the strongest contamination of environment simultaneously. Accordingly, to the basic task of "green" logistic, which consists in balancing of ecological and economic problems, in determination of optimal decisions at that at unchanging (or near to them) charges it is sorry inflicted by transport it will be an environment. The studies about a factor is undertaken in the article, that influence on efficiency of transport systems of cities, especially from the point of view of ecological constituent, and mathematical model have built, that allows to put and decide the task of forming and optimizations of functioning of transport systems of cities. Realizable practical development of complex algorithms that give an opportunity to expect the parameters of transpor- ecological processes, that is optimized with the aim of reduction of ecological contamination of city. Influence of a transport factor on the environment of city is considered on the example of city Mykolaiv, that has the wide, powerful system of transport, permanent freight and passenger streams and middle level of ecological contamination. For the complex decision of transport- ecological problems cities are applied approach is built on a pine methods of the dynamic programming and imitation design. His application does possible to put a task to optimization of functions of traffic control on the backbone network of transport highways with the different degree of working out on detail of municipal.

Abstract:
In this paper, we solved an ambulance location problem with a multi-objective framework considering the case of the study of Emergency Medical Service (EMS) of Antofagasta (Chile). Nowadays, in Antofagasta, the ambulances are located in bases that are not necessarily the optimal location achieving an estimated 67% of coverage under the 8 min not meeting the requirements dictated by the Chilean Ministry of Health. We used a multi-objective model considering mean response time, maximum response time, and the demand not covered. The model is solved using an iterative ε-constraint method to generate a Pareto set of efficient solutions. We considered historical data from the years 2015 and 2016 to generate the demand and emergency nodes with a clustering algorithm. The results show improvements on all criteria of the multi-objective model, where we highlight a potential increment on coverage within 8 min from 67 to 99%. In order to test the new policy in a real setting, a pilot plan is proposed, which reaches 89% of coverage within 8 min.

Abstract:
The relocation of containers is a crucial operation in container ports all around the world. The Container Relocation Problem (CRP) is focused upon to find a sequence of container retrievals in a defined order from a single yard container bay with a minimum number of relocations. The goal of this paper is to find out if Genetic Algorithm (GA) can give new insights in the problem of solving the CRP. In this paper we focus on the two-dimensional, static, offline and restricted CRP of real-world yard container bays. Four rules are proposed for determining the position of relocated containers. We applied GA to find the best sequence of container retrievals according to these four rules in order to minimize the number of relocations within the bay. The experimental testing was run on a total of 800 different instances with varying bay sizes and number of containers. The given results are compared with the results of different authors using other heuristic methods. The results show that the proposed model solves CRP and achieves near optimal solutions.

Abstract:
Abstract The increase of the utilization of public rail transportations is searched in directions for redistribution of the passenger travels between rail and bus transportation. The rail transport benefits by redistribution of the transportation flows on paths, predominantly supported by rails. The redistribution of the transportation is formalized by bi-level optimization problem. The upper level optimization estimates the maximal flow, which can be transported through a transportation network, supported both by bus and rail transports. The lower level optimization gives priority to the rail transport by decreasing the costs of flow distribution, using rail transport. This bi-level optimization problem was applied for the case of optimization of the rail exploitation in Bulgaria, defining priorities in transportation of the National transport scheme.

Abstract:
A new optimization model of Automated Storage and Retrieval Systems (AS/RS) containing three objective and four constraint functions is presented in this paper. Majority of the researchers and publications in material handling field had performed optimization of different decision variables, but with single objective function only. Most common functions are: minimum travel time, maximum throughput capacity, minimum cost, maximum energy efficiency, etc. To perform the simultaneous optimization of objective functions (minimum: “investment expenses”, “cycle times”, “CO 2 footprint”) the Non-dominated Sorting Genetic Algorithm II (NSGA II) was used. The NSGA II is a tool for finding the Pareto optimal solutions on the Pareto line. Determining the performance of the system is the main goal of our model. Since AS/RS are not flexible in terms of layout and organizational changes once the system is up and running, the proposed model could be a very helpful tool for the warehouse planners in the early stages of warehouse design

Abstract:
Studies on seaport operations emphasize the fact that the numbers of resources utilized at seaport terminals add a multitude of complexities to dynamic optimization problems. In such dynamic environments, there has been a need for solving each complex operational problem to increase service efficiency and to improve seaport competitiveness. This paper states the key problems of seaport logistics and proposes an innovative cross‐entropy (CE) algorithm for solving the complex problems of combinatorial seaport logistics. Computational results exhibit that the CE algorithm is an efficient, convenient and applicable stochastic method for solving the optimization problems of seaport logistics operations.

Abstract:
The universal application of the hub-and-spoke maritime network makes feeder line network key to restricting the quality and efficiency of maritime transportation. However, container liner routes in feeder line network are susceptible to the changes in shipment demand and international fuel prices. Therefore, based on the hub-and-spoke maritime network, this paper constructs a robust optimization model of container liner routes in feeder line network. Under the capacity and time constraints, routes optimization and ship equipment under uncertain environment are analysed. An improved tabu search algorithm was designed based on the characteristics of the model. The example analysis proves that the model can still ensure the robustness of routes under uncertain environment, which is more applicable than the deterministic model.

Abstract:
Nesta tese, nós apresentamos uma compilação de três artigos de otimização aplicados no contexto de transporte urbano de ônibus. O principal objetivo foi estudar e implementar heurísticas com base em Pesquisa Operacional para otimizar problemas de (re)escalonamento de veículos off-line e on-line considerando várias garagens e frota heterogênea. No primeiro artigo, foi proposta uma abordagem heurística para o problema de escalonamento de veículos múltiplas garagens. Acreditamos que as principais contribuições são o método de geração de colunas para grandes instâncias e as técnicas de redução do espaço de estados para acelerar as soluções. No segundo artigo, adicionamos complexidade ao considerar a frota heterogênea, denotada como multiple depot vehicle type scheduling problem (MDVTSP). Embora a importância e a aplicabilidade do MDVTSP, formulações matemáticas e métodos de solução para isso ainda sejam relativamente inexplorados. A principal contribuição desse trabalho foi o método de geração de colunas para o problema com frota heterogênea, já que nenhuma outra proposta na literatura foi identificada no momento pelos autores. Na terceira parte desta tese, no entanto, nos concentramos no reescalonamento em tempo real para o caso de quebras definitivas de veículos. A principal contribuição é a abordagem eficiente do reescalonamento sob uma quebra. A abordagem com redução de espaço de estados, solução inicial e método de geração de colunas possibilitou uma ação realmente em tempo real. Em menos de cinco minutos, reescalonando todas as viagens restantes.<br>In this dissetation we presented a three articles compilation in urban bus transportation optimization. The main objective was to study and implement heuristic solutions method based on Operations Research to optimizing offline and online vehicle (re)scheduling problems considering multiple depots and heterogeneous fleet. In the first paper, a fast heuristic approach to deal with the multiple depot vehicle scheduling problem was proposed. We think the main contributions are the column generation framework for large instances and the state-space reduction techniques for accelerating the solutions. In the second paper, we added complexity when considering the heterogeneous fleet, denoted as "the multiple-depot vehicle-type scheduling problem" (MDVTSP). Although the MDVTSP importance and applicability, mathematical formulations and solution methods for it are still relatively unexplored. We think the main contribution is the column generation framework for instances with heterogeneous fleet since no other proposal in the literature has been identified at moment by the authors. In the third part of this dissertation, however, we focused on the real-time schedule recovery for the case of serious vehicle failures. Such vehicle breakdowns require that the remaining passengers from the disabled vehicle, and those expected to become part of the trip, to be picked up. In addition, since the disabled vehicle may have future trips assigned to it, the given schedule may be deteriorated to the extent where the fleet plan may need to be adjusted in real-time depending on the current state of what is certainly a dynamic system. Usually, without the help of a rescheduling algorithm, the dispatcher either cancels the trips that are initially scheduled to be implemented by the disabled vehicle (when there are upcoming future trips planned that could soon serve the expected demand for the canceled trips), or simply dispatches an available vehicle from a depot. In both cases, there may be considerable delays introduced. This manual approach may result in a poor solution. The implementation of new technologies (e.g., automatic vehicle locators, the global positioning system, geographical information systems, and wireless communication) in public transit systems makes it possible to implement real-time vehicle rescheduling algorithms at low cost. The main contribution is the efficient approach to rescheduling under a disruption. The approach with integrated state-space reduction, initial solution, and column generation framework enable a really real-time action. In less than five minutes rescheduling all trips remaining.

Abstract:
We demonstrate that pulses derived using Optimal Control Theory (OCT) techniques can be used to significantly enhance the robustness of the Carr-Purcell-Meiboom-Gill sequence (CPMG) [1,2] to inhomogeneities in the static BB0 field. By numerically inverting the Liouville - von Neumann equation, OCT pulses were derived that can be used directly in place of hard pulses in the CPMG sequence to greatly improve the bandwidth of refocusing. To retain the echo stability achieved by the Meiboom-Gill correction to the Carr-Purcell sequence, the refocusing pulses were designed to perform a unitary π-rotation as opposed to just a state inversion transfer. To illustrate this approach we present an example of optimized pulses that show an improved CPMG-like behavior with complete excitation and multiple refocusing over a bandwidth of +/- 2.6 γB1,max B with a pulse duration limited to 10 t180.

Abstract:
<p>A ship scheduling problem in optimization of water-borne crude oil transportation has been investigated. The classic optimization problem the most closely related to the problem at hand is the Multi-Vehicle-Pick-up-and-Delivery Problem with Time Windows (m-PDPTW). In addition to the basic characteristics of the m-PDPTW, the studied problem has an additional degree of freedom due to having pick-ups and deliveries that are not matched. This extra freedom gives new possibilities when creating effective heuristics when dealing with transportation problems. The studied problem has been presented in relation to carefully selected background literature. On this basis a proposed heuristic has been developed, and implemented using some already existing structures in the commercial decision support system TurboRouter. The studied problem is an industrial shipping problem, an operational mode where the shipper owns the cargo to be transported. No income is therefore made directly from transporting goods. Therefore the objective function chosen was net income, which in this mode is the same as minimizing the net expenses. A multi-start local search with pre-matching of pick-ups and deliveries heuristic was chosen based on an assessment of problem size, problem type, real life applicability and existing software. This heuristic consists of three main parts. First the pick-ups and deliveries are matched and merged in a pre-matching heuristic, and then a large number of initial solutions are generated by an insertion heuristic. The best initial solutions are then improved by a local search. Two strategies were developed for pre-matching and then tested. The one with the best test results was subsequently used in the heuristic. This multi-start local search with pre-matching of pick-ups and deliveries heuristic has been subject to rigorous testing and was compared to a single-start local search and multiple initial solutions heuristic. The solutions generated by the multi-start local search heuristic were superior compared to those of the other heuristics, but the computation time necessary was high and higher than those of the heuristics which it was compared to. This high computation time is partially believed to be a result of flexible data sets resulting in broad solution spaces. In addition some computationally expensive heuristics were deployed, increasing the computation time. In real life applications, finding a solution relatively quickly is of importance. Therefore the heuristic may need to be simplified and used on "tighter" data sets than some sets used in testing to be real life applicable.</p>

Abstract:
This study aims to improve transportation held between six auction centers, Inter-Auction Transportation, of FloraHolland. FloraHolland serves ninety eight percent of the Dutch market and is the largest auction in floriculture industry. The company wants to give the best sale opportunities with the costs as low as possible and this is the main initiative of this study. In this line of thought, FloraHolland wants to have a improvement on its current routing and scheduling mechanism. Exact models do not work due to the complexity and the size of the problem. Therefore, we developed a two-stage approach specific to this study. With this approach, we split exact approach into two, a mathematical model followed by a heuristic. In the exact approach, trucks are routed and scheduled at the same time. On the other hand, our solution approach first determines most efficient routes to be followed with Cycle Assignment Model and then, with Scheduling Heuristic, trucks are assigned to the routes, so within day transportation is planned in detail. Overall, each stage of this approach works in harmony and brings good solutions in a short CPU time.

Abstract:
The ever-increasing demand for broadband services by end-user devices utilising 3G/4G/LTE and the projected 5G in the last mile will require sustaining broadband supply from fibre-linked terminals. The eventual outcome of the high demand for broadband is strained optical and electronic devices. The backbone optical fibre transport systems and techniques such as dense wavelength division multiplexing (DWDM), higher modulation formats, coherent detection and signal amplification have increased both fibre capacity and spectrum efficiency. A major challenge to fibre capacity and spectrum efficiency is fibre-faults and optical impairments, network management, routing and wavelength assignment (RWA). In this study, DWDM and flexible spectrum techniques such as wavelength assignment and adjustment, wavelength conversion and switching, optical add and drop multiplexing (OADM) and bitrate variable transmission have been experimentally optimized in a laboratory testbed for short- and long-haul optical fibre networks. This work starts by experimentally optimising different transmitters, fibre-types and receivers suitable for implementing cost effective and energy efficient flexible spectrum networks. Vertical cavity surface-emitting lasers (VCSELs) and distributed feedback (DFB) lasers have been studied to provide up to 10 Gb/s per channel in 1310 nm and 1550 nm transmission windows. VCSELs provide wavelength assignment and adjustment. This work utilises the non-return-to-zero (NRZ) on-off keying (OOK) modulation technique and direct detection due to their cost and simplicity. By using positive intrinsic negative (PIN) photo-receivers with error-free BER sensitivity of -18±1 dBm at the acceptable 10-9-bit error rate (BER) threshold level, unamplified transmission distances between 6 km and 76 km have been demonstrated using G.652 and G.655 single mode fibres (SMFs). For the first time, an all optical VCSEL to VCSEL wavelength conversion, switching, transmission at the 1550 nm window and BER evaluation of a NRZ data signal is experimentally demonstrated. With VCSEL wavelength conversion and switching, wavelength adjustments to a spectrum width of 4.8 nm (600 GHz) can be achieved to provide alternative routes to signals when fibre-cuts and wavelength collision occurs therefore enhancing signal continuity. This work also demonstrates a technique of removing and adding a wavelength in a bundle of DWDM and flexible channels using an OADM. This has been implemented using a VCSEL and a fibre Bragg grating (FBG) providing a wavelength isolation ratio of 31.4 dB and ~0.3 𝑑𝐵 add/drop penalty of 8.5 Gb/s signal. As a result, an OADM improves spectrum efficiency by offering wavelength re-use. Optical impairments such as crosstalk, chromatic dispersion (CD) and effects of polarization mode dispersion (PMD) have been experimentally investigated and mitigated. This work showed that crosstalk penalty increased with fibre-length, bitrate, interfering signal power and reduced channel spacing and as a result, a crosstalk-penalty trade-off is required. Effects of CD on a transmitted 10 Gb/s signal were also investigated and its mitigation techniques used to increase the fibre-reach. This work uses the negative dispersion fibres to mitigate the accumulated dispersion over the distance of transmission. A 5 dB sensitivity improvement is reported for an unamplified 76 km using DFB transmitters and combination of NZDSF true-wave reduced slope (TW-RS) and submarine reduced slope (TW-SRS) with + and – dispersion coefficients respectively. We have also demonstrated up to 52 km 10 Gb/s per channel VCSEL-based transmission and reduced net dispersion. Experimental demonstration of forward Raman amplification has achieved a 4.7 dB on-off gain distributed over a 4.8 nm spectral width and a 1.7 dB improvement of receiver sensitivity in Raman-aided 10 Gb/s per wavelength VCSEL transmission. Finally, 4.25-10 Gb/s PON-based point to point (P2P) and point to multipoint (P2MP) broadcast transmission have been experimentally demonstrated. A 10 Gb/s with a 1:8 passive splitter incurred a 3.7 dB penalty for a 24.7 km fibre-link. In summary, this work has demonstrated cost effective and energy efficient potential flexible spectrum techniques for high speed signal transmission. With the optimized network parameters, flexible spectrum is therefore relevant in short-reach, metro-access and long-haul applications for national broadband networks and the Square Kilometre Array (SKA) fibre-based signal and data transmission.

Abstract:
Ces dernières années, les problèmes environnementaux sont fortement associés à l'industrie des transports, les modes de transport de marchandises deviennent plus que la contribution la plus importante entre les autres secteurs. Malgré les avantages du transport intermodal, il a toujours des impacts négatifs, qui sont associés aux émissions. Cependant, la pollution est devenue intéressante entre les secteurs académique et industriel. Ainsi, pour atténuer les impacts négatifs du transport de marchandises, cela gagne de plus en plus en pertinence dans le domaine de la logistique. Pour répondre à ces enjeux et défis, pour identifier les apports de la logistique verte à l'optimisation du transport de marchandises, augmenter l'efficacité des opérations d'optimisation liées à la plateforme de transport multimodal.Le fonctionnement optimal du transport de conteneurs est particulièrement important lorsque le transport de marchandises de manière écologique peut être réalisé en combinant différents modes de transport et en coordonnant des activités telles que la recherche du chemin le plus court. Dans le système de transport multimodal de conteneurs, la sélection du mode de transport et de l'itinéraire a un effet important sur le processus de transport des conteneurs de transport. Dans cette thèse, pour organiser le transport multimodal de manière plus efficace, le facteur de routage des conteneurs est considéré avec le facteur de trajet du mode de transport. On étudie l'influence des caractéristiques incertaines du fonctionnement du nœud sur le mode de transport et le choix de l'itinéraire dans le processus de conversion du mode de transport du transport multimodal conteneurisé. Pour minimiser le coût total, un modèle de programmation mixte avec des contraintes de temps est introduit. La transformation graphique est utilisée pour transformer le problème en modèle de chemin le plus court avec des caractéristiques aléatoires et des contraintes de temps de transport dans les opérations de nœud. En vérifiant et en analysant les résultats, le chemin obtenu est acceptable d'un point de vue coût et temps. Ainsi, cela réduit la congestion du trafic et minimise les émissions. Dans le contexte de la congestion du trafic et de la réduction des émissions, cette thèse propose une technologie de peloton pour améliorer la consommation de carburant, la flexibilité routière et optimiser les opérations de transport de conteneurs. Dans cette thèse, un système de téléphérique pour le transport de petites marchandises est proposé et analysé afin de réduire la congestion du trafic dans la zone urbaine.La recherche conclue à l'optimisation des plates-formes de transport multimodal vise à réduire les impacts négatifs sur l'environnement et à maximiser la rentabilité en maximisant les services offerts qui minimisent le coût total de transport ainsi que le temps de transport entre chaque paire de nœuds Origine-Destination (OD) dans le réseau de transport. Ces travaux contribuent également à réduire les émissions de dioxyde de carbone en diminuant la consommation de carburants et en réduisant les coûts d'exploitation. Sur la base de ces travaux, des plates-formes de transport de conteneurs plus efficaces et efficientes peuvent être réalisées. Cette thèse introduit la base théorique de l'optimum de transport multimodal qui permet l'intégration entre différents modes. Parallèlement, il contribue à la logistique de l'efficacité du transport multimodal / intermodal<br>In recent years, environmental issues are highly associated with the transport industry, modes of goods transport become more than contribution as largest between other sectors. Despite the benefits of intermodal transport, it still has negative impacts, which are associated with emission. However, pollution has become interesting between academic and industrial sectors. Thus, to mitigate the negative impacts caused by goods transport, that gains more and more relevance in the logistics domain. To meet these issue and challenges, to identify the contributions that green logistics to the optimization of freight transport, the increase the efficiency of the multimodal transport platform related optimization operations.The optimal operating of container transport is particularly important where goods transport in an environmentally way can be achieved by combining different modes of transport and coordinating activities such as finding the shortest path. In the multimodal container transport system, the selection of the transport mode and route has a large effect on the transport container transport process. In this thesis, to organize multimodal transport in a more efficient manner the container routing factor is considered along with the path factor of transport mode. The influence of the uncertain characteristics of the node operation on the transport mode and route choice in the process of converting the transport mode from containerized multimodal transport is studied. To minimize the total cost, an integer mixed programming model with time constraints is introduced. The graphical transformation is used to transform the problem into the shortest path model with random characteristics and transport time constraints in the node operations. By verifying and analyzing the results, the path obtained is acceptable from a cost and time perspective. Thus, this reducing traffic congestion and minimizing emissions. In the context of traffic congestion and emissions reduction, in this thesis a platoon technology is proposed to improve to reduce fuel consumption, road flexibility and optimize container transport operations. In this thesis, a ropeway system for the transport of small-scale goods is proposed and analyzed to reduce the traffic congestion within the urban area.The research concluded to optimization multi-modal transport platforms aims to reduce negative impacts on the environment and maximize profitability maximizing the services offered that minimize the total transportation cost as well as minimize the transportation time between each pair of Origin-Destination (O-D) nodes in the transport network. This work also contributes to reducing carbon dioxide emissions by decreasing consumption fuels and reducing operating costs. Based on this work, more effective and efficient container transport platforms can be achieved. This thesis introduces the theoretical base of optimal of multi-modal transport which can integration between different modes. Meanwhile, it contributes to logistics of multi/inter-modal transport efficiency

Abstract:
In the proposed work, an optimization model of transportation of municipal solid waste (MSW) of the urban agglomeration carried out by the waste processing and disposal complex is formulated and investigated. The complex includes waste processing plants, landfills and transport enterprises. Optimization here means minimizing the costs (fuel, time, finance) for the transportation of MSW from their accumulation sites (garbage sites) to processing points (waste processing plants) and landfills (landfills).
