This paper analyses the component of the Integrated Interlocking System which forms the central logical and functional unit implementing all logical and computational functions necessary for railway traffic control in the Railway 4.0 concept. The main principle is that this approach centralizes the technology of station interlocking system, track line interlocking systems, level crossing interlocking systems and the functions of train interlocking system - the line part of ETCS L2/3 radio block control panel (RBC). The operation control is centralised to the controlling dispatcher centres. The paper discusses the concept of integrated interlocking system including safety issues addressed from the perspective of the requirements of CENELEC standards EN 50126, EN 50128 and EN 50129. These requirements are addressed from the perspective of the authors of the paper, who also work as independent assessors of the safety of railway control and command systems.

Public administration implements decisions of elected bodies, i.e., deals with the governance of public issues, ensures compliance of practice with law. Public administration creates sustainable economic prosperity, ensures social cohesion and human well-being. Public administration has very often been seen as a service to the population; its quality affects not only social confidence in the public sector but also in the whole political system. From the economic point of view, public administration represents a managerial structure ensuring mainly the supply of public goods; the allocation function of the public sector and its ability to efficiently provide public goods and public services are particularly important. The paper describes the context of territorial public administration in the Czech Republic, where all municipalities are obliged to provide basic administrative services and local public services. Public libraries and elementary schools represent traditional public services provided by communities and towns. Using the data envelopment analysis (DEA) method, the paper focuses on assessing the economic efficiency of providing these two traditional public services.

The article deals with the issue of applying the Data Envelopment Analysis (DEA) method, when examining the efficiency of selected public services provided by municipalities. It focuses on typical services provided by most municipalities, such as the operation of local libraries and primary schools. It describes the methodological basis for calculating the efficiency of municipalities divided into smaller, more homogeneous groups. It then shows the practical results of the efficiency calculation – the mean values achieved in the categories examined and the selected groups of municipalities in the context of the whole set. The method of creation and operation of the software application created for the purpose of DEA calculation is then described.

Metro rail systems are increasingly becoming relevant and inevitable in the context of rising demand for sustainable transportation methods. Metros are therefore going to have a consistently expanding user-base and hence user satisfaction will require meticulous planning. Usage forecast is clearly an integral component of metro planning as it enables forward looking and efficient allocation of resources leading to greater commuter satisfaction. An observation from studying the usage of Kochi Metro Rail Ltd. is that there is a consistently occurring temporal pattern in usage for every station. But the patterns differ from station to station. This hinders the search for a global model representing all stations. We propose a way to overcome this by using station memorizing Long Short-Term Memory (LSTM) which takes in stations in encoded form as input along with usage sequence of stations. This is observed to significantly improve the performance of the model. The proposed architecture with station parameter is compared with algorithms like SVR (support vector regression) and neural network implementation with the best architecture to testify the claim. The proposed model can predict the future flow with an error rate of 0.00127 MSE (mean squared error), which is better than the other models tested.

Multistream Compression has proven to be competitive in terms of compression ratio. It utilizes a binary tree structure which follows practically the same rules for its construction as the Huffman method. This tree structure is ideal in terms of compression ratio for creation of codewords by Huffman compression. Comparing to the Huffman method the Multistream Compression is based on different idea of how to compress data. This fact raises the question whether the same tree structure provides the best performance. The presented paper investigates possible improvements of the tree structure. A genetic algorithm application was created for this purpose. The design of this application is presented in the paper as well as the obtained results. The whole application is set to the context of the MSC trees.

The paper deals with the comparison of cities, which will allow to identify reserves in the management of public funds and in the provision of services to its residents. The first step in the comparison is to determine the parameters that can be used to compare a set of cities. An appropriate choice of parameters allows performance comparison across a wide range of areas. A very interesting method for comparison seems to be the DEA method, which allows a relative comparison of a set of cities. Relative comparisons are advantageous if the best values of the parameters that can be achieved are not known, but at the same time it is necessary to compare comparable cities. The paper describes the use of DEA method for comparing cities with each other. The DEA description includes an illustrative example showing the differences between VRS, CRS and FDH models. Paper also describes the software application that is developed for the purpose to compare the efficiency of municipalities. The paper describes the architecture of the application, its functions and print screens from the web interface.

Kompresní algoritmus MSC (MultiStream Compression) je nová bezeztrátová kompresní metoda českého vědce Jiřího Kochánka. Jiří Kochánek implementoval svůj algoritmus softwarově v programovacím jazyce C. Na Fakultě dopravní ČVUT byla vytvořena první hardwarová implementace - do hradlového pole (FPGA). Části algoritmu byly transformovány na množinu spolupracujících konečných automatů a zapsány v jazyce VHDL. Navíc bylo nutné navrhnout speciální reprezentaci kódovacího stromu (Left Tree Representation) s ohledem na potřeby algoritmu.

Communication of a system alliance with surroundings can be modelled as a translation of specific languages. Incoming messages into alliance create an input language LI, outgoing messages from alliance create an output language LA. Elements on the boundaries serve as conversion units between external input languages and internal languages, or they serve as plain acceptors of input sentences, telling only the input sentence is valid/non-valid. Very important case is man - machine communication. In this case, the respective languages have to be regular. The example of two alliance interfaces and/or respective correction processes is discussed in detail. The process of the acceptance of a new (unknown) word within the adaptive acceptor is carried-out in the following part. These analyses are of high value for both the control and design of complex uncertain wholes, as well as for increasing their functionality and reliability.

Presented contribution is dedicated to discussion of two different approaches into increase of programming language safety. They are language subset and extension of original safety mechanisms. As examples we used MISRA C/C++ subset and SPARK language build on the base of ADA language. In the last chapters we discuss novel approaches based on application of programmable hardware which is described in VHDL language, which is also modification of ADA language. Especially SPARK and VHDL languages represents novel approaches to safe system development which are now discussed in relation to new Railway SW projects.

Nowadays we can observe two opposite approaches to modification of programming languages to be more suitable to safe system development. The first is the reduction of chosen programming language expressions to safe subset, like MISRA C/C++ and this approach is also supported by today standards of safe software development like ISO61508 or EN50128. In the last few years, novel and partially opposite development is expanded. It is based on extension of original language by additional explanations containing description of such aspects of software, that are not described enough by original language. Typical example is SPARK language precisiating original ADA one even though it was originally designed as language specialized to safe control system development.

Increasing demands to railway capacity require to build new railway lines and to apply new approaches like information technologies. There are several new trends in rail traffic control. Firstly, the control is shifted from distributed system spread over stations to centralized one in all Europe. The most railway lines in the Czech Republic should be controlled from two offices in Přerov and Prague. The centralization of the operation control gives spread view of the situation but information quantity to evaluate by operators increases. Secondly, next modern trend (especially in Switzerland, Belgium and Germany) is a separation of strategy control (route planning from daily to annual interval) from operative control (conflicts solution caused by deviations from regular time-table due to infrastructure or vehicle faults) and from direct control (safety device operation, shunting). Each level of operation control process specific functions. Operative control IT support should react to deviation from planed daily time table; it monitors actual trains routes and solves potential conflicts with others trains in advance (from minutes to hours). The output is modified conflict-free time table – specific route plan transmitted to direct control level (realized by human operator or automatic system).

This paper describes the first attempt of hardware implementation of Multistream Compression (MSC) algorithm. The algorithm is transformed to series of Finite State Machines with Datapath using Register-Transfer methodology. Those state machines are then implemented in VHDL to selected FPGA platform. The algorithm utilizes a special tree data structure, called MSC tree. For storage purpose of the MSC tree a Left Tree Representation is introduced. Due to parallelism, the algorithm uses multiple port access to SDRAM memory.

Basic information on Smart City modeling approach based on the concept of the System alliance is presented. An advantage of this approach inter alia is that System alliances are naturally able to model the synergic effects on interfaces and to minimize various negative impacts. Two ways of interfaces modeling within the alliance are discussed: (i.) Quantum-like models and (ii.) the utilization of the duality: automaton-language. In the first case the superposition of states or even the entanglement concepts are suitable tools for recording non-orthogonal interface parameters and resulting phase sensitivity of the respective interface. In the second approach processes on interfaces are modeled as mutual translations of specific languages. Due to significant uncertainties the methodology of genetic algorithms and grammatical evolution are tested.

A modern way of solving logistics problems is using some evolutionary techniques such as genetic algorithm. The best known logistic problems are TSP (Traveler Salesman Problem) and VRP (Vehicle Routing Problem). There are many experiments and approaches when genetic algorithms are applied to solve these problems. Genetic algorithms use two basic operators: crossover and mutation. Number of variations of crossover operators are known in genetic algorithm and a special ERX (Edge Recombination Crossover) was developed for this problem [1][2][4]. Classical TSP and VRP try to find an optimal solution by minimization of the length of travelling distances. In this paper, the fitness function contains time constrain as a criterion except of travelling distance. The fitness function is multidimensional and the lexicographical order is defined. Experiments showed that it is very useful to change the priorities of parts of fitness, especially when time constrain is not performable. This paper is based on the BS thesis [3] submitted to the Department of Informatics and Telecommunications, Faculty of Transportation Sciences, Czech Technical University in Prague.

The paper presents theory of two FSMs that share internal states or input symbols. Modified definitions of FSMs are presented and two reciprocal meaningful transformations between the pair of FSMs sharing input symbols and the pair sharing internal states are constructed. Transformations are based on Mealy to Moore FSM and Moore to Mealy FSM transformations. Conditions of transformations are discussed and minimization of FSMs is shown. Practical aspects are discussed.

Our FSM construction using genetic algorithm was presented in previous years. The algorithm was tested on several tasks. Some of them were very difficult for GA - tasks where FSMs recognize given subsequences in the serial bit sequences. Transition graphs of these FSMs contain trees as their sub-graphs. The last improvement of the algorithm uses a language representation of the FSM and the grammatical evolution. The FSM is described by switch command like in the C language. The syntax of the language is defined by context-free grammar. The FSM is coded by linear codon. A new criterion computing the count of loops was added to the fitness function. The improvement was verified on difficult problems by experiments.

The paper presents a concept of two FSMs sharing elements. Transformation of a pair of independent Mealy FSMs sharing input symbols to other pair of FSM with separated inputs and sharing internal states and back transformation are constructed. The concept of pairs of FSM that share some of their component was introduced in "Dynamics of System Alliances" project [6]. The transformation of FSMs sharing input symbols was already discussed in [6] but the back transformation has not been published yet. So, two types of reciprocal meaningful transformations are presented which are based on Mealy to Moore FSM and Moore to Mealy FSM transformations. Practical aspects are discussed.

Our approach to the FSM construction using genetic algorithm was presented in a several contributions. The FSM was represented by matrices. The one-point crossover operator mixed two matrices and the mutation changed one transition or output. Very difficult tasks were these ones where FSMs recognize given subsequences in the serial bit sequences. Transition graphs of these FSMs contained trees as their sub-graphs. The algorithm achieved certain fitness and then it stagnated on. We modified the mutation operator. We defined and computed the distance between two FSMs and we add the distance measurement into the mutation operator. Now the mutation changes the FSM so that the distance between the original FSM and mutated one is greater than predefined threshold.

This paper introduces a method how to transform one regular grammar to the second one. The transformation is based on regular grammar distance computation. Regular grammars are equivalent to finite states machines and they are represented by oriented graphs or by transition matrices, respectively. Thus, the regular grammar distance is defined analogously to the distance between two graphs. The distance is measured as the minimal count of elementary operations over the grammar which transform the first grammar to the second one. The distance is computed by searching an optimal mapping of non-terminal symbols of both grammars. The computation itself is done by the genetic algorithm because the exhaustive evaluation of mapping leads to combinatorial explosion. Transformation steps are derived from differences in matrices. Differences are identified during the computation of the distance.

This article introduce the method how to compute regular grammars distances. Grammars are equivalent to finite states machines and they are represented by oriented graphs. Then the grammar distance is defined as graph distance between two graphs (finite state machines). The computation itself is done by the genetic algorithm because the exhaustive graph comparison leads to combinatorial explosion. The grammar transformation is based on optimal mapping nonterminal symbols which is a product of the distance computation. Transformation steps are given by differences identified during the distance computation.

The transformation of a pair of FSMs with common inputs to the pair of FSMs having separated inputs and sharing internal state is presented. The effect is the coupling between FSMs wich is shifted from the outside of FSMs into inside. The disadvantage of the transformation is the growth of internal state number.
