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.

Abstract:

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:

Transport processes research are closely related to the economic and operational performance of road transport. During planning road transportation, the most important factor is the transport services cost. Known fact that most of the transportation costs are car fuel. The share of car fuel in the transport tariff cost can be 25-50% (depending on the working conditions of vehicles). Therefore, research that is associated with improving the vehicles efficiency by reducing variable costs is appropriate and relevant. The article presents the results of research on the planning of transport processes in the road transport performance in international road transport for the return flight and calculating methods the demand for the amount of fuel purchased in different countries with different prices. The author presents the results of theoretical and experimental research the adequacy of the mathematical model (methodology). The specified mathematical model consists in substantiation of a technique of calculation of quantity of car fuel, definition of the variable factors influencing volumes of fuel expenses, calculation of correction factors (total) received on the basis of technical and operational indicators of vehicles and the influencing factors connected with features of road transport work. . The second part of the research contains the results of the development of an algorithm development to calculate the total cost of automotive fuel, which was purchased at different prices in several countries. Thus, the main purpose of research is the task of substantiating the algorithm (mathematical model – methodology) for determining fuel costs by the criterion of the highest use of fuel in countries at the lowest prices.

Abstract:

This paper focuses on the optimization of container shipping network and its operations under changing cargo demand and freight rates. The problem is formulated as a mixed integer non-linear programming problem (MINP) with an objective of maximizing the average unit ship-slot profit at three stages using analytical methodology. The issues such as empty container repositioning, ship-slot allocating, ship sizing, and container configuration are simultaneously considered based on a series of the matrices of demand for a year. To solve the model, a bi-level genetic algorithm based method is proposed. Finally, numerical experiments are provided to illustrate the validity of the proposed model and algorithms. The obtained results show that the suggested model can provide a more realistic solution to the issues on the basis of changing demand and freight rates and arrange a more effective approach to the optimization of container shipping network structures and operations than does the model based on the average demand.

Abstract:

This paper presents multi-criteria warehouses location problem in the logistics network. In order to solve this problem the location model was developed. The limitations and optimization criteria of the model were determined. Optimization criteria refer to transportation costs, costs associated with warehouses, e.g.: local taxes, expenditure on starting the warehouse, the constant costs, the labour force costs, the purchase costs of the additional land for the expansion, the transition costs of the raw material via the warehouses. The final location of warehouse facilities was obtained using a genetic algorithm. The genetic algorithm was developed in order to solve the multi-criteria warehouses location problem. This paper describes the stages of the genetic algorithm i.e. the stage of designating the initial population, the crossover and mutation process, the adaptation function. In this paper, the process of calibration of this algorithm was presented. The results of the genetic algorithm were compared with the random results.

Abstract:

In this paper, we formulate a cost and safety oriented approach to optimize the motorail transport car loading layout optimization problem. The model has 2 objective functions, one maximizes the wagon loading weight utilization rate, and another minimizes the gravitational center height after loading the cars on the wagons. The calculation results show that: the heaviest cars should be loaded in the middle of the decks, the cars weight loaded on both sides should be gradually reduced; the total weight of cars loaded on lower deck should be larger than the total weight of cars loaded on the upper deck.

Abstract:

In this paper, under the consideration of two carbon emissions policies, the issues of optimizing ship speed and fleet deployment for container shipping were addressed. A mixed-integer nonlinear programming model of ship speed and fleet deployment was established with the objective of minimising total weekly operating costs. A simulated annealing algorithm was proposed to solve the problem. An empirical analysis was conducted with the data selected from the benchmark suite. The applicability and effectiveness of the established model and its algorithm are verified by the results. According to the results, two policies of the cap-and-trade programme and the carbon tax can better optimize the results of the ship speed and fleet deployment problem to achieve the goal of reducing carbon emissions. The research remarks in this paper will provide a solution for container shipping companies to make optimized decisions under carbon emissions policies.

Abstract:

At the phase of 13-th five-year plan in China, natural gas will play an important role in energy revolution. With the growth of consumption, natural gas infrastructures will become hot spots of future investment and pipeline network construction will also usher in a period of rapid development. Therefore, it is of great theoretical and practical significance to study layout methods of transport pipeline network. This paper takes natural gas transport pipeline network as a research object, introduces dominance degree to analyse benefits of pipeline projects. Then, this paper proposes Dominance Degree Model (DDM) of transport pipeline projects based on Potential Model (PM) and Economic Potential Theory (EPT). According to DDM of gas transport pipeline projects, layout methods of pipeline network are put forward, which is simple and easy to obtain the overall optimal solution and ensure maximum comprehensive benefits. What’s more, construction sequences of gas transport pipeline projects can be also determined. Finally, the model is applied to a real case of natural gas transport pipeline projects in Zhejiang Province, China. The calculation results suggest that the model should deal with the transport pipeline network layout problem well, which have important implications for other potential pipeline networks not only in the Zhejiang Province but also throughout China and beyond.

Abstract:

Nowadays, air transport is the most modern and the most dynamically developing branch of transport. This intensive development of air transport causes the continuous increase in emissions of pollutants, mainly greenhouse gases, leading to the deepening of the greenhouse effect, which in turn leads to irreversible global climate change. In order to optimize air communication and make it even more economical and environmentally friendly, such activities as e.g. SESAR project are undertaken. One of the parts of this project is the research on minimizing fuel consumption and emissions of pollutants in jet engine exhausts. The paper presents a developed model of emission and main pollutants (NOx, CO, HC and CO2) in the exhausts of jet engines of a passenger aircraft during a cruise phase. Applying simple optimization tools, such as e.g. the Dijkstra’s algorithm, this model was verified by the optimization of a trajectory of a jet aircraft in a cruise phase on an exemplary route in terms of minimizing emission of selected harmful compounds in jet engines exhausts. To meet the aim of the research, it was necessary to develop a computer program that determines a two-dimensional grid graph, assigns its appropriate weights to its edges and passing along these edges, determines the optimal trajectory of a given flight between two indicated start and end vertices. The developed research methodology is universal and can be applied for any jet passenger aircraft.

Abstract:

Negative changes in the environment, leading to public pressure and environmental legislation require fundamental changes in the industrial practice of business. Survey of the environment in 22 countries found that: in half of the countries surveyed, the environment is considered to be one of the three most serious problems of concern to society. In most countries, the overwhelming number of citizens surveyed indicated that the state of the environment had an impact on their health, and an even larger proportion stated that the environment had an impact on the health of their children. The article deals with the problem of increasing the level of environmental friendliness of transportation in supply chains. With the modern requirements in the integrated green supply chain, the reduction of the harmful impact of production and logistics activities on nature should be considered at all stages of the technological cycle of product development and its promotion through the supply chain. It is determined that the key technologies for reducing the anthropogenic impact on the environment are the optimization of transport processes due to the reduction of distance during transportation at all stages of the supply chain; the increase in the use of local resources (reducing fuel costs and harmful emissions); the use of modern environmentally friendly energy-efficient vehicles. The basic principles and approaches of the consolidated cargo transportation model have been substantiated, which balances environmental and economic problems and their testing has been carried out in the supply chain of the Epicenter hypermarket chain

Abstract:

Abstract In world practice, one of the main features of integrated transport systems, is the delivery of goods "door-to-door", which is impossible without the road transport is being used at the final stage of transportation. Today, the situation on the Ukrainian roads has a negative trend in terms of traffic jams and accidents, which creates a risk of delay or damage to freight during the transportation process. The problem is how to optimize the urban transport network to meet the growing demand for transportation and reduce traffic congestion. Purpose. Investigate the root causes of traffic congestion and develop a tool in order to optimize the city network on the example of a traffic interchange. Analytical and experimental with the use of computer 3D-simulation. For a practical demonstration, a model of one of the most problematic, from the point of view of traffic jams, transport interchanges in Kyiv, was developed. An optimization experiment was conducted, which demonstrated an increase in interchange capacity by 26,2% and reduction in average transportation time by 60, 47%. It is a difficult task to optimizing the transport network, because if you conduct an experiment with a real system, any changes could be catastrophic. In addition, it is necessary to anticipate the growth of traffic, take into account the economic, territorial and industrial characteristics of settlements. The research clearly demonstrates the possibilities of simulation computer modeling in this aspect. The purposed solution allows to optimize the city transport network without significant investment, and could reduce the risk of accidents, financial and time costs for transportation of goods by city in the global aspect. Keywords: freight transport, intersections, integrated transport systems, urban transport network, optimization, imitation modeling.

Abstract:

The article describes a proposed planning organization and productivity simulation tool, with a special emphasis on orientations to the optimization of operations in a maritime container terminal. With the application of an adequate model frame for traffic and technical‐technologic forecasting, infrastructure and manpower planning and productivity simulation are possible to measure and increase the productivity in the whole subsystem of the maritime container terminal. The emphasis is mainly put on setting up planning organization in order to collect important information and consequently to raise productivity. This is the main task and goal of terminal management that must develop elements and strategies for optimal operational and financial production. An adequate planning structure must use simplified but efficient simulation tools enabling owners and management to take a vast number of adequate financial and operational decisions. Considering all important and very dynamic facts in container and shipping industry, the proposed simulation tool gives a helpful instrument for checking productivity and its time variation and monitoring a competitive position of a certain maritime terminal with the terminals from the same group. Therefore, the management of every maritime container terminal must establish an appropriate internal planning system as a mechanism for strategic decision support relating basically to the assessment of the best development and optimization solutions for the infrastructure and suprastructure of the entire system.

Abstract:

The research in this article relates to an evaluation system for the implementation of lines in a public passenger transport system as a public service obligation. The purpose of this research is to present the methodology for the performance evaluation of a public passenger transport system that serves the public transport authority as a tool for making further decisions. The procedures first refer to the experimental determination of the criteria and then perform the first evaluation in the form of the value of the objective function. This is followed by multi-stage linear regression and optimization procedures that give the relation between the dependent variable ( Y ) and the independent variables ( X , ) that is, the criteria. Optimization is carried out in the coefficients ( β ), which are excluded from the optimization procedures in the case of the calculated statistical degree of insignificance. This research also shows procedures for changing the mathematical form of the criteria records and determining the impact on the final result of optimizations.

Abstract:

Terrain slugging is extremely likely to occur sometime during the life of a deep subsea pipeline/riser system. But, can the terrain slugs be mitigated? In this study, we performed transient multiphase flow simulations to explore the feasibility of sea floor separation to mitigate terrain slugging and to optimize fluid transport from wellhead to downstream processing. We considered the effects of separator location and separation efficiency on production system behavior. We found that there is an optimal amount of gas underflow into the liquid line and there is an optimum location for subsea separator. Our study also covered how the operational transient processes, such as startup and shutdown, would affect the performance of the pipeline/separator system. It is necessary to have a good understanding of the performance of subsea separation system before a reliable one can be designed. The results of this study are aimed toward improving the design of sea floor processing for ultra-deepwater production. [S0195-0738(00)00403-9]

Abstract:

MC transport parameters used are common to all egs++ applications. The eﬀect of each transport parameter need to understand to optimize the simulation process. Therefore, the purpose of this study was to investigate the efficiency of egs++ simulation for different transport parameters in water phantom. This water phantom has built using slab. Collimated source defined 100 cm above the phantom. The simulation parameters such as the efficiency, statistical uncertainty, and accuracy of selecting transport parameters such as electron and photon cut-oﬀ energies, spin eﬀects, atomic relaxations, and bound Compton scattering was investigated. The selection of ECUT and PCUT greatly affects the simulation time. The simulation time, efficiency and energy fractions have same value for varied ECUT except for 0.521 MeV. The energy fraction have been shifted but the simulation time and efficiency were same. Turning on spin effects in this simulation increases simulation time by 25%. The simulation time increases by about 15% when relaxations are turned on. The more accurate result of deposited energy using EGSnrc algorithm is about 30% slower than the less accurate PRESTA-I algorithm. Therefore, The optimization of transport parameters is needed in the simulation of egs++ to provide the best efficiency.

Abstract:

The article proposes methodological approaches to the study and optimization of traffic flows using simulation modeling by the example of one of the street intersections in the city of Novosibirsk. Possible stages of sequential implementation of analytical and practical measures for optimizing transport flows are given. It is proposed to use the AnyLogic environment as a modeling tool. When creating the simulation model, satellite images of the area were used, inserting an image of the analyzed section of the road network on top of the satellite image, setting objective indicators of traffic intensity, developing and optimizing a vehicle movement algorithm. The results of the study make it possible to assert that AnyLogic environment tools are an adequate way to optimize traffic flows. Optimization measures made it possible, based on adjusting the duration of traffic light control phases, to reduce the average time spent by cars at the intersection by 35% and, thereby, increase the throughput of the intersection by 10%. The use of the proposed approaches to the development of traffic simulation models is a promising direction for optimizing traffic control at urban intersections.

Abstract:

This paper deals with the process of traction force realization described by a suitable mechanical model and is pointed to the adhesion phenomenon as a physical one, i.e. is a suitable factor that the value of traction force depends on. The model for the process of optimizing locomotive traction force based on using the fuzzy set theory is explained. The projecting process of a fuzzy controller regulating the value of skidding and the value of traction torque by increasing the value of traction force that can be realized according to adhesion conditions is described. Finally, testing the optimization model in several numerical examples under specific conditions of wheel-rail adhesion is done.
