Application of Multi-Criteria Analysis of Determining Sea Port Development Models in the Spatial Concept of a Town, Based on the Example of the Town of Rovinj

A significant problem in port and port area development is the awareness that port development plans for county and local ports brought by port authorities in the capacity of a body managing the port and its port area, are often not covered by town and county physical planning solutions, and vice versa. The above said indicates that relevant parties in port area planning (port management and towns/countries) are not always active participants in the procedure of planning the ports and port areas in physical planning documents. County spatial plans do not pay necessary attention to the role, significance and development of the ports of county and local relevance. Drafting the spatial plans related to the ports of county and local relevance demands high level of expertise and multidisciplinary approach, as well as knowledge on the problem of physical planning, port operation and marine and coastal biology, maritime traffic technology and maritime environment protection. The purpose and the goal of this paper is to find the optimum model and measures for developing county and local ports in relation to the complementarity of spatial concept of the port and the town. For the purpose of defining and setting up the model, we used the most important indicators and measures that influence the level of physical planning of the port and the town. The example of Town of Rovinj will serve for checking and proving efficiency of the set-up model

Facilitating Seafarers Employment Using a Common Database

A key part of the maritime crewing agent business is the employment of seafarers (apart from drafting contracts between ship owners and seafarers), finding suitable personnel to fill the job vacancies advertised by ship owners. Maritime crewing agencies generally keep records of seafarers in their own databases. However, those databases often happen to fall short of the requested professionals (officers) and/or the support staff. In such cases, agencies spend a lot of time on finding the personnel possessed of the required qualifications and experience. This paper researches the positive and negative sides of a common database of seafarers, their meaningfulness or drawbacks, and the attitudes of maritime crewing agencies relating to common databases. A survey was conducted among Croatian maritime crewing agencies in order to obtain information on their operations and opinions concerning the proposed common seafarer database

Supply chain – a key factor of the sustainable development of city centers

In the paper importance is given to the organization of the supply chain for a more efficient delivery of goods to city centers. Logistics activities are closely related because they depend on each other. The ultimate goal is to bring the product/goods to the end customer/consumer as soon as possible, on time, at the lowest cost, in perfect condition and in the appropriate quantity. The mutual coordination and cooperation of all participants in the supply chain can result in a satisfied end-user/customer. The development of information – telecommunication technologies – will greatly affect the future development and efficiency of the supply chain by finding new transport solutions that would mostly affect city centers. The paper mostly emphasizes the context of the delivery conditions in Rijeka’s city center with a proposal for the location of a future centralized distribution center

Analysis of the implementation of various forms of professional practice at the Faculty of Maritime Studies, University of Rijeka

The paper presents the results of research carried out in the framework of the project PANDORA financed by the European Social Fund. In the first phase of the research, the initial state of implementation of professional practice at the Faculty of Maritime Studies, University of Rijeka was analyzed in workshops with students, while the questionnaire filled in by employers analyzed the way professional practice is carried out in companies. Using both methods, limitations and shortcomings in the implementation of professional practice were identified and guidelines for its improvement were established. Based on the guidelines obtained, an attempt was made over a period of one year to improve various forms of professional practice in the Faculty of Maritime Studies. The performance of the various forms of professional practice was assessed through questionnaires completed by students after professional practice. The forms of professional practice assessed included simulator work, field work, practicums and navigation practice. The results showed that better assessment mechanisms for the different forms of professional practice were established during the observation period, as well as a stronger connection of the tripartite student-professor-employer relationship, resulting in a greater number of master's and bachelor's theses and research projects in collaboration with industry. It was also concluded from the positive student surveys that greater availability of professional practice in the curricula and reinforcement of a more innovative approach facilitated the acquisition of practical knowledge and skills by the target groups.Peer Reviewe

The Single Window Concept in International Trade, Transport and Seaports

This paper presents a review of electronic data exchange and Single Window concept in international trade, transport and seaports. The theoretic framework of international trade, trade facilitation, Single Window, transport sector, maritime transport and seaports is provided, as well as the definition of electronic data exchange and standards for data exchange. The time and cost (excluding tariffs) associated with documentary compliance procedure (exporting and importing a shipment of goods) are shown in order to better understand the complexity and the importance of simplifying administrative processes. The importance of stakeholder connectivity in the transport sector (with special emphasis on seaports) is demonstrated, and factors which affect the successful electronic data exchange in seaports are shown. The advantages of smoother electronic data exchange are provided through the analysis of several Single Window examples, which present regional best practices

Integrating Maritime National Single Window with Port Community System – Case Study Croatia

A single point of data entry for documentary requirements and procedures in maritime transport - Maritime National Single Window (MNSW) includes process integration of all stakeholders in the entire seaport system. The primary goal of the MNSW is to eliminate data redundancy in a way that the entered data is instantly visible in other systems, according to the set level of authorization and authentication. In many seaports, the administrative MNSW is connected to the commercial Port Community System (PCS), an information system for the exchange of cargo related commercial data. The linking of the MNSW and the PCS connects the administrative with the commercial business aspect, making seaport business processes more efficient and more effective. Both interfaces can only be developed by using process reengineering and presume significant investments in underlying information technologies. Such implementation requires in-depth analysis of all stakeholders’ processes in the seaport system, in order for both systems to complement each other

Distribution center logistics optimization model – City of Rijeka case study

The optimization of the goods delivery to Rijeka’s city center presents a complex organizational framework where many parameters must be taken into account and a diverse multi-methodological approach, needs to be utilized. The building of a distribution center is asserted here to be one notable way to improve the existing delivery service. The grouping of freight in a distribution center would result in a reduction of transport costs due to a smaller number of vehicles entering the city center, in turn reducing the traffic burden incumbent on the city’s transport network. In this paper, two of the many possible methods related to the optimization of goods delivery in city centers, have been used. Based on the data collected through the study’s questionnaire, conducted in the area of the city of Rijeka, the method of gravity center has been used to determine the location of the distribution center. Then, based on the tentative location of the distribution center, the method of optimization of the transport process has been applied by resorting to transport problem-solving methods, including several different implementation scenarios. From the proposed solutions, and based on the results detailed, the solution that was found to be the most credible was arguably the best match with the default criterion

Evaluation model of the inflow of goods to city centers for improvement of sustainable city logistics

Logistika grada ima zadaću razvijati i implementirati mjere za postizanje učinkovitog i ekološki prihvatljivog gradskog prometnog sustava. Razvoj gradskog središta za posljedicu ima grupiranje sve većeg broja poslovnih subjekata u gradskom središtu što rezultira povećanjem količine roba koje ulaze u gradsko središte, stvaranje dodatnih zagušenja u prometu, tzv. uskih grla, što pak za posljedicu ima povećanu razinu buke i emisiju štetnih ispušnih plinova, čime je nezadovoljstvo kvalitetom života gradskog stanovništva sve izraženije. Planiranje dostave roba u gradska središta bez teorijske i znanstvene potpore, kao i praktične primjene načela održivog i pametnog razvoja, pritom ne uvažavajući interese svih interesnih skupina logistike grada, negativno utječe na održivi razvoj gradskog središta. Time se javlja potreba za promišljanjem o razvoju upravljanja tokovima dostave roba u gradsko središte s ciljem unapređenja održive logistike grada. U doktorskoj disertaciji predložen je opći model vrednovanja tokova dostave roba u gradska središta, temeljen na sustavnom pristupu, generiranju mogućih scenarija dostavnih aktivnosti unutar gradskog središta, odabiru onih kriterija za evaluaciju koji doprinose razvoju dostavnih aktivnosti i njihovom vrednovanju od strane pojedinih interesnih skupina. Analizom relevantne znanstvene literature i motiva (interesa) interesnih skupina (prijevoznici, gospodarski subjekti, lokalno stanovništvo i javna uprava) odabrani kriteriji su podijeljeni u nekoliko skupina: tehničko-tehnološki, ekonomsko-financijski, organizacijski i društveni kriteriji. Također, predloženi su mogući scenariji dostave roba unutar gradskog središta; status quo, dostava iz jednog konsolidacijskog centra, dostava iz dvaju konsolidacijskih centara, dostava ekološki prihvatljivim vozilima iz jednog konsolidacijskog centra te livability scenarij. Navedene skupine kriterija i pojedinačni kriteriji vrednovale su relevantne interesne skupine kako bi se utvrdila važnost (težina) pojedinih kriterija na razvoj dostave roba u gradsko središte. U doktorskoj disertaciji primijenjena je višeučesnička-višekriterijska analiza (MAMCA) koja se temelji na optimizaciji i rangiranju scenarija sukladno zadanom cilju, problemu istraživanja, definiranim kriterijima i interesima interesnih skupina. Rješenje MAMCA analize sukladno zadanom cilju optimizacije najbolje vrednuje scenarij s dva konsolidacijska centra. Dodatno su se svi scenariji testirali na primjeru tokova dostave roba u gradsko središte grada Rijeke putem simulacijskog alata VISSIM. Testirajući scenarije, uz ograničenja primjene simulacijskog alata i odabira kriterija vrednovanja najbolji scenarij dostave roba je iz jednog konsolidacijskog centra. Na temelju dobivenih rezultata višeučesničke-višekriterijske analize i provedene simulacije u realnom okruženju grada Rijeke, III zaključuje se da se postojeći način dostave roba u gradu Rijeci (status quo) može unaprijediti izgradnjom konsolidacijskog centra. Dodatno, dostava robe ekološki prihvatljivim vozilima može bitno utjecati na poboljšanje kvalitete života u gradskom središtu. Doktorskom disertacijom dokazalo se da pri donošenju odluka vezanih uz dostavne aktivnosti unutar gradskog središta treba uzeti u obzir interese interesnih skupina, kriterije za vrednovanje te moguće scenarije tokova roba u gradsko središte te dobivene rezultate testirati u stvarnom okruženju grada kako bi se doprinijelo unapređenju održive logistike grada.The task of city logistics is to develop and implement measures for achievement of effective and ecologically acceptable traffic system. Development of city centre leads to grouping of large numbers of business operators in the city centre, resulting in the increase of the quantity of goods entering the city centre, causing additional traffic congestion, the so called bottlenecks, eventually causing higher levels of noise and emission of exhaust gasses which leads to major dissatisfaction with the quality of life of city population. Planning of delivery of goods into city centres without theoretical and scientific support, as well as without the practical application of the principles of sustainable and smart development, without taking into consideration the interests of all stakeholders in city logistics, have a negative impact on the sustainable development of the city centre. A need to deliberate the development of management of delivery of goods to city centre in order to improve the sustainable city logistics becomes imminent. The doctorate thesis proposes a general model of evaluation of delivery activities to city centres, based on a systematic approach, generation of possible scenarios of delivery activities within the city centre, selection of criteria for evaluation which contribute to the development of delivery activities and their validation by specific stakeholders. The analysis of relevant scientific literature and motives (interests) of stakeholders (carriers, economic operators, local population and public administration) led to division of selected criteria into several groups: technical – technological, economic – financial, organizational and social. Possible scenarios for delivery of goods within the city centre have also been proposed: status quo, delivery using a single consolidation centre, delivery using two consolidation centres, delivery by ecologically acceptable vehicles of one consolidation centre and livability scenario. The stated groups of criteria and the individual criteria were validated by relevant stakeholders in order to determine the importance (weight) of individual criteria on development of delivery of goods to the city centre. A multi-actor multi-criteria analysis (MAMCA), based on optimization and ranking of scenarios in line with the set goal, research problem, defined criteria and interests of stakeholders was used in the thesis. The solution of MAMCA analysis in accordance with the set goal of optimization evaluates the scenario with two consolidation centres as the best one. Additionally, all scenarios were tested on an example of delivery of goods to Rijeka city centre using a simulation tool VISSIM. Testing the scenarios, with limitations in application of the simulation tool and possible selection of evaluation criteria, the scenario of delivery of goods from one consolidation centre is proposed as the best solution. Based on the results of multi-actor-multi- criteria analysis and the implemented simulation in the real environment of the city of Rijeka, it is concluded that the existing model of delivery of goods to Rijeka city centre may be improved by construction of a consolidation centre. The construction of the consolidation centre significantly reduces the distance between the origin and the delivery point resulting in significant saving in time of arrival to the delivery point and particularly in lower consumption of fuel. Additionally, implementation of delivery by ecologically acceptable vehicles can definitely have a positive impact on the quality of life in the city centre. The doctorate thesis has proven that in the process of making decisions relating to delivery activities within the city centre it is important to take into consideration the interests of stakeholders, criteria for evaluation and possible scenarios for courses of delivery of goods to city centres. The results arising thereof should be tested in the real environment of the city in order to contribute to the improvement of sustainable city logistics
