Opis:
The article presents a method of selecting a fleet of vehicles with a homogeneous structure for tasks based on the statistical characteristics of their operational parameters. The selection of a vehicle fleet for tasks is one of the stages of vehicle fleet management in transport companies. The selection of a vehicle fleet for tasks has been defined as the allocation of a vehicle model to a given company, which is associated with the unification of the vehicle fleet to one specific type. The problem of selecting a fleet of vehicles has been presented in a multi-criteria approach. The operational parameters assessing the selection of vehicles for the tasks are mileage and the number of days to the first and subsequent failure, and vehicle maintenance costs. The developed method of selecting a fleet of vehicles for the tasks consists of two stages. In the first stage, the average operating parameter values are determined using statistical inference. In the second stage, using the MAJA method, a unified model of the fleet of vehicles operating in the enterprise is established.

Opis:
With vast range of applications in real life situations, the Vehicle Routing Problems (VRPs) have been the subject of countless studies since the late 1950s. However, a more realistic version of the classical VRP, where the distribution of goods is done from several depots is the Multi-Depot Vehicle Routing Problem (MDVRP), which has been the central attraction of recent researches. The objective of this problem is to find the routes for vehicles to serve all the customers at a minimal cost in terms of the number of routes and the total distance travelled without violating the capacity and travel time constraints of the vehicles, and it is handled with a variety of assumptions and constraints in the existing literature. This survey reviews the current status of the MDVRP and discuss the future direction regarding this problem.

Opis:
The aim of this paper was to determine the differences in the designed and manufactured model of a suspension. A set of key parameters was compared, including camber and toe in angles and their change w.r.t wheel travel, as well as the motion ratio. It also focused on the possibility of accurately determining the suspension system kinematics using affordable measuring devices available on the market. First, the design process, main goals and project assumptions were briefly described. Next, the CAD model and manufacturing process was presented. Finally, the measurements of both computer and real model were performed. The obtained results were compared and a significant difference between models was observed. The reason of such variation could not be determined unambiguously, as there were numerous factors that could potentially influence the results. Moreover, it was proven that accurate determination of kinematics is impossible using the given set of measuring devices.

Opis:
This paper presents a novel sideslip angle estimator based on the pseudo-multi-sensor fusion method. The kinematics-based and dynamics-based sideslip angle estimators are designed for sideslip angle estimation. Also, considering the influence of ill-conditioned matrix and model uncertainty, a novel sideslip angle estimator is proposed based on the wheel speed coupling relationship using a modified recursive least squares algorithm. In order to integrate the advantages of above three sideslip angle estimators, drawing lessons from the multisensory information fusion technology, a novel thinking of sideslip angle estimator design is presented through information fusion of pseudo-multi-sensors. Simulations and experiments were carried out, and effectiveness of the proposed estimation method was verified.

Opis:
Vehicle delay and stops at intersections are considered targets for optimizing signal timing for an isolated intersection to overcome the limitations of the linear combination and single objective optimization method. A multi-objective optimization model of a fixed-time signal control parameter of unsaturated intersections is proposed under the constraint of the saturation level of approach and signal time range. The signal cycle and green time length of each phase were considered decision variables, and a non-dominated sorting artificial bee colony (ABC) algorithm was used to solve the multi-objective optimization model. A typical intersection in Lanzhou City was used for the case study. Experimental results showed that a single-objective optimization method degrades other objectives when the optimized objective reaches an optimal value. Moreover, a reasonable balance of vehicle delay and stops must be achieved to flexibly adjust the signal cycle in a reasonable range. The convergence is better in the non-dominated sorting ABC algorithm than in non-dominated sorting genetic algorithm II, Webster timing, and weighted combination methods. The proposed algorithm can solve the Pareto front of a multi-objective problem, thereby improving the vehicle delay and stops simultaneously.

Opis:
Safe, efficient and user-friendly transportation of people and goods have been a premier point of concern for all the developed and the developing countries around the globe. National Highway N-5 or GT road is the most important highway link in Pakistan. It carries about 80% of the country freight traffic. When this heavy traffic passes through the twin cities of Rawalpindi and Islamabad, it causes congestion and environmental hazards particularly in business centers of Rawalpindi city. Because of this heavy traffic volume passing through the cities situated along N-5, bypasses to all of them have been provided however, Rawalpindi is the only city along N5 which is still without a bypass. A bypass to Rawalpindi city is, therefore, inevitable. Besides this, the Bypass will also provide a short access to the traffic on the Motorway (M2) destined for the western part of Rawalpindi. For this research work, Rawalpindi Bypass is taken as a hypothetical scenario and is evaluated for its benefits. Besides addition to the networks of highways across Pakistan, this bypass has many other benefits which include a decrease in congestion from Islamabad and Rawalpindi main arteries (ISB Highway and IJP Road) that results in travel time savings, vehicle operating cost savings, safety savings, and reduced air pollution. This research aims to produce an engineering and scientific comparison of various costs and benefits associated with the road agency and users about the construction of an alternative. The Project involves transportation demand estimation on different segments of the National and Arterial roads, Project Costs, travel time savings, safety saving, vehicle operating cost savings, economic efficiency analysis, Air quality impact and multi criterion transportation decision making. The transportation decision making process usually involves the evaluation of effectiveness and efficiency of an alternative decision with respect to a base case DO-NOTHING Scenario. The authors have taken the existing roadway structure with no improvements as DO-NOTHING Scenario, whereas the construction of Rawalpindi Bypass (60 km) with 2 lanes in each direction is taken as Alternative B and Rawalpindi Bypass (51 km) as Alternative C. Multi criteria decision making technique is used for decision because of multiple options with different dimensions, both monetary and non-monetary. Basing of MCDM this study recommends Alternative C (51 km) for Rawalpindi Bypass.

Opis:
The degree of emission limitation achieved through improved efficiency of combustion engine vehicles can no longer set off additional emissions caused by increasing traffic activity. As the restriction of greenhouse gas emissions from cars is expected to be particularly difficult, the air pollution and excessive dependence of road transportation on oil cannot be improved without the implementation of new mobility concepts (biofuels, hybrid drives, electric vehicles). The lack of these concepts, as emphasized in the White Paper, will preserve transportation dependence on crude oil so deeply that only 10% of energy will be derived from renewable sources. According to this scenario, until 2050 the CO2 emissions in the transportation sector will increase by one-third compared to 1990. Moreover, there will be an increase in the costs of traffic congestion until 2050 by ca. 50%. The difference in the availability between central and peripheral areas and social costs of accidents and noise pollution will increase as well (EC, 2011). The goal of the paper is to determine whether the implementation of a new solution would actually improve the situation of air pollution, traffic noise, etc. To this end, the paper proposes a comparative analysis of cars with various sources of energy using a multi-criteria scoring method. Notably, this method has never been used in such a confrontation before. Until now, the multi-criteria assessment methods have been used i.a. to evaluate implementation variants for infrastructural investment projects in rail transport (Jacyna and Wasiak, 2007), traffic flow distribution (Jacyna and Merkisz, 2014; Wasiak et al., 2017), supply chain efficiency (Jacyna-Gołda et al., 2018), effectiveness of vehicle allocation for tasks in supply chains (Jacyna-Gołda et al., 2017), etc.

Opis:
An elementary indicator of a car steerability, the understeering gradient, is determined on the basis of dependency of the steering wheel turn angle changes in the vehicle lateral acceleration function. So called comparative dynamic wheel turn angle is a component of an appropriate calculation formula, in which - for multi-axle vehicles - there exists so called equivalent wheelbase Le of a substitute twoaxle vehicle. This paper analyses methods for determining this parameter. There was used a substitute bicycle model of the vehicle with an equivalent wheelbase Le, to which a flat model of a multi-axle vehicle can be compared. There have been presented and compared two analytical methods of calculation that were illustrated with concrete examples of figures. Deliberations presented in this paper can be used to support calculations when analysing the steerability tests of three-axle and four-axle special vehicles, including the High Mobility Wheeled Platform (HMWP) – a universal purposes prototype vehicle.
Podstawowy wskaźnik kierowalności samochodu, gradient podsterowności, jest wyznaczany na podstawie zależności zmian kąta obrotu kierownicy w funkcji przyspieszenia poprzecznego pojazdu. Członem odpowiedniego wzoru obliczeniowego jest tzw. porównawczy, dynamiczny kąt skrętu koła, w którym, dla pojazdów wieloosiowych, występuje tzw. ekwiwalentny rozstaw osi Le, zastępczego pojazdu dwuosiowego. W pracy przeanalizowano metody wyznaczania tego parametru. Wykorzystano zastępczy, rowerowy model pojazdu, z ekwiwalentnym rozstawem osi Le., do którego można sprowadzić płaski model pojazdu wieloosiowego. Przedstawiono i porównano dwie, analityczne metody obliczeń, które zilustrowano konkretnymi przykładami liczbowymi. Rozważania przedstawione w pracy mogą być wykorzystane do wspomagania obliczeń przy analizie badania kierowalności trzyosiowych i czteroosiowych pojazdów specjalnych, w tym także kołowej Kołowej Platformy Wysokiej Mobilności (KPWM) – prototypowego pojazdu uniwersalnego zastosowania.

Opis:
The idea of a new evolutionary algorithm with memory aspect included is proposed to find multiobjective optimized solution of vehicle routing problem with time windows. This algorithm uses population of agents that individually search for optimal solutions. The agent memory incorporates the process of learning from the experience of each individual agent as well as from the experience of the population. This algorithm uses crossover operation to define agents evolution. In the paper we choose as a base the Best Cost Route Crossover (BCRC) operator. This operator is well suited for VPRTW problems. However it does not treat both of parent symmetrically what is not natural for general evolutionary processes. The part of the paper is devoted to find an extension of the BCRC operator in order to improve inheritance of chromosomes from both of parents. Thus, the proposed evolutionary algorithm is implemented with use of two crossover operators: BCRC and its extended-modified version. We analyze the results obtained from both versions applied to Solomon’s and Gehring & Homberger instances. We conclude that the proposed method with modified version of BCRC operator gives statistically better results than those obtained using original BCRC. It seems that evolutionary algorithm with memory and modification of Best Cost Route Crossover Operator lead to very promising results when compared to the ones presented in the literature.

Opis:
A path planning problem for a heterogeneous vehicle is considered. Such a vehicle consists of two parts which have the ability to move individually, but one of them has a shorter range and is therefore required to keep in a close distance to the main vehicle. The objective is to devise an optimal path of minimal length under the condition that at least one part of the heterogeneous system visits all desired waypoints exactly once. Two versions of the problem are considered. One assumes that the order in which the waypoints are visited is known a priori. In such a case we show that the optimal path can be found by solving a mixed-integer second-order cone problem. The second version assumes that the order in which the waypoints are visited is not known a priori, but can be optimized so as to shorten the length of the path. Two approaches to solve this problem are presented and evaluated with respect to computational complexity.

Opis:
This paper deals with some computational study of multi-criteria optimization in fuel distribution problem. We consider vehicle routing problem, e.g. routing of a fleet of tank trucks, for one of the famous polish petroleum companies. For the purpose of solving this problem, we developed the random search algorithm, which explores the broad range of feasible sets of routes and searches for non-dominated multi-criteria solutions. The problem is examined on real data, which contains distances between 50 petrol stations and one central warehouse (refinery). Obtained results indicate, that it is possible to obtain single solution and satisfy both optimization criteria. Based on the analysis of the collected data, we formulate a number of proposals useful in future for construction of algorithms for multi-criteria fuel distribution optimization.
