Integrated management system of a transport company

Unaprjeđenjem proizvoda i usluga kao preduvjeta poslovnog uspjeha na tržištu, raste potreba za efikasnim sustavima upravljanja što rezultira intenzivnim razvojem normizacije. U interesu je vlastitog tržišnog položaja praćenje pomaka u razvoju normi i promjenama koje one donose. Sustav upravljanja kvalitetom, okolišem, zdravljem i sigurnosti na radu predstavlja moderan način organiziranja rada i upravljanja tvrtkom pa se menadžment svake organizacije, tako i prijevozničke tvrtke, susreće s problemom koji je ovdje postavljen kao zadatak. Predmet istraživanja ovog rada je analiza mogućnosti i načina, prednosti i nedostataka uvođenja sustava i organiziranja rada prema zahtjevima međunarodnih normi primijenjenih na prijevozničko poduzeće, a iz perspektive njegovog menadžmenta. Opisani su zahtjevi pojedinih točaka normi radi istraživanja konkretne primjenjivosti u prijevozničkom poduzeću. Rad je prezentacija dovoljnog broja jasnih i sažetih informacija na jednom mjestu a zamišljen je kao svojevrsna smjernica menadžmentu prijevozničkog poduzeća prilikom odluke o uvođenju sustava sukladno zahtjevima normi.The improvement of products and services as precondition for the business success on the market means an increase in the need for efficient management systems which in turn results in intensive development of standardization. It is in the interest of one’s own market position to monitor the shift in the development of standards and the resulting changes. Quality, environment, occupational health and safety management systems represent a modern way of organizing work and company administration so that the management of every organization, including transport companies, encounters a problem which is here set as a task. The subject of research in this paper is the analysis of the possibilities and methods, advantages and drawbacks of introducing the systems and organizing work according to the requirements of international standards applied to a transport company, from the perspective of its management. The requirements of single items of the standards have been described in order to study the concrete applicability in the transport company. The paper is a presentation of a sufficient number of clear and concise pieces of information in one place, and it has been conceived as kind of a guideline for the transport company management during decision-making about the introduction of the system pursuant to the requirements of the standards

Modeling the Permeable Power of the Road on a Semaforized Crossing Using Petri Nets

With the growth in demand and the development of traffic over the last fifty years, the need for the introduction of Intelligent Transport Systems (ITS) is growing every day. With a modern approach they solve complex traffic problems. One modern approach is modeling the dynamics of Petri Nets. The Petri Nets is a powerful graphical and mathematical model for working with discrete systems. This paper describes how using a Petri Net can manage signaled intersections, assist in choosing the best alternative route, or manage an intersection at which an incident occurred. The research was carried out in a real traffic environment, at the intersection of Zagrebačka Road and Bistrička Road in the center of the city Sesvete, by modeling with coloured timed Petri Nets

Prognostic trend model of passenger transport performance of the Croatian maritime traffic system

This research analyses the dynamics and the modelling trend of the development of passenger transport performance of the Croatian maritime traffic system. Passenger transport performance represents a transport value which is, regarding its characteristic, a qualitative transport demand indicator in public passenger traffic, and expressed by the realized passenger transport operation in public maritime passenger traffic. Adequate mathematical statistic analysis of passenger transport performance has been performed at the level of maritime traffic system, forming in turn a mathematical prognostic trend model of the development dynamics of this traffic value. The prognostic trend model of the passenger transport performance is presented by a respective equation, with the calculation of the related determination coefficient as a measure of quality which determines the level of statistical significance of the description of the given data using the model equation. The law of development of the studied transport value during the considered time period is described by the computer calculated obtained model equation.

Methodological Approach for Evaluation and Improvement of Quality Transport Service in Public Road Passenger Transport

Achieving the appropriate level of quality transport service is essential in the operations of the carriers in the public road intercity line passenger transport due to an increased competition between road carriers in the market of transport services. Effective assessment of achieved competitiveness is important for the survival and development of public road passenger carriers. The problem of research is reflected in the appropriate organization and giving importance to the criteria of quality of transport service in order to improve the methodology of its evaluation with the aim of optimizing business and competitiveness in public road intercity line passenger traffic. An efficient method for evaluating the quality of transport service would solve the problem of assessing the quality of transport service and assessing the competitiveness of bus carriers. It is proposed to develop a multi-criteria model for evaluating the quality of transport services by the method of measuring passenger satisfaction. The developed VAZP model (Multicriteria Analysis of Passenger Satisfaction) is based on multicriteria analysis AHP (Analytical Hierarchical Process) which is based on the disaggregated approach and linear programming modeling. The results of the research will be described using numerical values and will be graphically presented using descriptive statistical analysis. The ability to qualitatively represent passengerꞌs judgments and preferences makes the model a suitable tool for assessing passenger satisfaction and evaluating quality service in the transportation sector, as well as strategically positioning and gaining a competitive opportunities in the transportation services market. Using the Expert Choice software tool and sensitivity analysis it would establish differences between reached level of the quality of transport service of individual bus carriers and propose possible improvements to the business to gain a competitive advantage in the market of transportation services. Systematic optimization and quality management through continuous assessment of market competitiveness contributes to the development of the business of companies for road passenger transportation

Development of Small Entrepreneurship in the Republic of Croatia

Poduzetništvo kao razvojna i pokretačka snaga svakogg ospodarstva temelj je uspješnosti pojedine države. Bio mali, srednji ili veliki poduzetnik, svaki od njih ima odgovornost koju je preuzeo rizikom započinjanja bilo kakvog novog posla jer svaki novi posao ili ideja koja se treba ostvariti, otkriva pravog poduzetnika. Svaka mala ideja koja kroz provedbu postaje veliki posao daje priliku za daljnji razvoj poduzetnika, ali i potiče razvoj cjelokupnoga gospodarstva. Svakodnevno smo svjedoci nastajanja novih “poduzetnika” koji za razvoj vlastitog posla koriste vlastita, ali i tuđa, novčana i robna sredstva. Pravi poduzetnik je upravo onaj koji svoju ideju provede u djelo. Mali poduzetnici su najčešći poduzetnici koji kroz osnivanje vlastitih obrta ili trgovačka društva ostvaruju svoje poslovne snove. Mala trgovačka društva se suočavaju s problemima i uvjetima nemilosrdne tržišne utakmice obilježene velikim brojem bankrota i financijskih problema. U ovom se radu osvrćemo na situaciju u stanju malog gospodarstva u Republici Hrvatskoj te na problematiku na koju nailaze poduzetnici u svome radu.Entrepreneurship is a driving force of any economy and as such, the foundation of a country’s success. Whether we speak of small, medium or large enterprises, each of them has responsibility assumed by taking on a risk of starting a new business, because every new idea to be realized reveals a true entrepreneur. A small initial idea can become a big business in the course of its implementation, thereby ensuring further development of entrepreneurs, but also contributing to the growth of the entire economy. New “entrepreneurs” are emerging on a daily basis, funding their start-ups with their own or borrowed means. A true entrepreneur is the one who manages to realize his or her idea. Small entrepreneurs account for the largest proportion of new businesses. They have to deal with conditions of ruthless competition characterized by a large number of bankruptcies and financial problems. In this paper we address the situation of small business n the Republic of Croatia and the problems faced by entrepreneurs in conducting their business
