Predmet istraživanja u okviru ove doktorske disertacije jeste model logistike primorskih turistickih podrucja, koja predstavljaju poseban i jedinstven turisticki prostor sa vecim brojem gradova i više manjih turistickih mjesta. Karakteristika ovih podrucja, jeste da su ona u svom razvoju dominantno inkorporirala istorijisku komponentu, sa svim karakteristikama u pogledu: (i) bliske povezanosti sa vodnom površinom, (ii) zbijenih gradskih jezgara sa koncentracijom generatora logistickih aktivnosti u okviru istih, (iii) uskih jednosmernih ulica sa otežanom realizacijom teretnog transporta, (iv) zagušenja na prilaznim putevima u odredenim vremenskim intervalima, (v) dominantne zastupljenosti drumskog vida saobracaja u dopremi robe, (vi) želje da se nade adekvatan model snabdijevanja gradskog jezgara i turistickih naselja, a da to ne naruši kvalitet turisticke ponude i ambijenta. Istraživanje relacije: geografski prostor profil logistike klasterizacija (zoning) mrežna struktura logistickih centara lokacijsko-alokacijski problem optimizacija procesa snabdijevanja predstavlja osnovu modeliranja u disertaciji. Shodno tome, razvijen je novi originalni integrisani model logistike turisticko regiona - MoLoTuRe, za koga je primjenom kombinatorne optimizacije definisana optimizaciona procedura Dynamic multiechelon, multiitem locating problem with heterogenous fleet – DYMEMULP. Model predstavlja multidimenzionalni konceptualni model razvoja turistickog regiona u cilju postizanja vecih ekonomskih, prostornih, tehnicko – tehnoloških i ekoloških efekata. Isti povezuje sistemsku, transportnu, organizacionu i informaticku koncepciju. Kod razvoja modela imao se u vidu zadatak koji isti treba da ostvari, a to je, optimalno i savremeno povezivanje više funkcija: tranzit, skladištenje i snabdijevanje regiona, u jedan funkcionalni model, koji treba da inkorporira strategije i koncepcije logistike (JIT, outsourcing, 3PL, 4PL,...). Osnovna karakteristika ovakvog modela logistike jeste, primjena logistickih principa u povezivanju privrednih, tranzitnih i snabdevackih funkcija turistickih regiona i orijentacija na ocuvanje životne sredine, nareduciranje teretnog transporta, na preraspodjelu robnog transporta izmedu drumskog i vodnog vida transporta i stvaranje sistema koji ce integrisati, koordinisati i kontrolisati robne tokove i sisteme, u cilju razvoja više sfere usluge turistickih podrucja. U uslovima prisutne ekspanzije logistickih aktivnosti u turistickim podrucjima, i sve veceg prostornog ogranicenja u okviru istog, kreiranje kooperativnog modela distribucije predstavlja jedno od mogucih održivih rešenja. U težnji da se eliminiše sve što je nepotrebno u procesu realizacije logistickih tokova, nametnula se ideja unapredenja postojecih distributivnih sistemskih rešenja, kako bi krajnji rezultat bio razvoj win - win situacija svih ucesnika u logistickom lancu. Nova distributivna rešenja zasnovana na kooperaciji drumskog i vodnog sistema transporta, mogu uticati na stvaranje niza pozitivnih efekata: (i) smanjenje ukupnih troškova logistike turistickih subjekata, (ii) povecanje fleksibilnosti, pouzdanosti i kvaliteta u snabdijevanju objekata, (iii) smanjenje zagušenosti saobracaja, (iv) smanjenje ekološkog zagadenja, (v) kreiranje više sfvere turisticke usluge, (vi) povecanje stepena bezbjednosti, itd. The subject of research within this PhD thesis, is the logistic model on seaside tourist areas, which presents special and unique tourist space with a large number of cities and several smaller tourist localities. Characteristic of these areas is that they, within their devepolment, predominantly incorporated hystorical component in all its characteristics, more precisely: (i) close connection with water area, (ii) thick city nucleus with high concentration of logistic activity generators within the same, (iii) narrow one-way streets with difficult realization of cargo transport, (iv) congestions on approach roads in specific time intervals, (v) predominant road transportation in delivery of goods, (vi) desire to find appropriate model of supply to city nucleus and trourist settlements, in a way not to disturb the quality of tourist offer and ambient. Research of relations: geographical space profile of logistics clustering (zoning) network structure of logistic centers location-allocation problem optimization of delivery process represents the basis of modeling in the thesis. In accordance with that, a new original integrated model of logistics for tourist regions - MoLoTuRe has been developed, for which, through application of combinatorial optimization, a optimization procedure Dynamic multiechelon, multiitem locating problem with heterogenous fleet – DYMEMULP has been defined. The model itself presents a multidimensional conceptual model of development of tourist region aiming at reaching bigger economic, spatial, technical – technological and envronmental effects. It is connecting systematic, transport, organizational and informatics concepts. At model development, the objective that needs to be reached has been borne in mind, i.e. optimal and modern connection of several functions, such as: transit, storage, and supply of regions, within one functional model which also needs to ncorporate logistic strategies and concepts (JIT, outsourcing, 3PL, 4PL, ...). Basic characteristic of this logistic model is implementation of logistic principles in connecting economic, transit and supply functions of tourist regions and orientation towards environmental protection, reduction of transport of goods, redistribution of transport of goods between road and water means of transport and creation of the system that will integrate, coordinate and control goods flows and systems, aiming at development of a higher sphere of services in tourist regions. In circumstances of existing expansion of logistic activities in tourist regions, as well as constantly increasing spatial limits within the same, creation of a cooperative model of distribution represents one of possible sustainalbe solutions. With the aim to eliminate everything that is unnecessary in the process of realization of logistic flows, the idea of improving existing distribution system solutions has been imposed, having as final result development of win – win situations for all participants in logistic chain. New distribution solutions based on cooperation between road and water systems of transport, may have an influence on making the series of positive effects: (i) reduction of overall costs of logistics for tourist subjects, (ii) increase of flexibility, reliability, and quality in supplying objects, (iii) reduction of traffic congestions, (iv) reduction of environmental pollution, (v) creation of a higher sphere of tourist service, (vi) increase of sefety level, etc.

Grad je mesto najveće koncentracije ljudi, privrednih i društvenih delatnosti, a logistika je izuzetno važna za njegovo funkcionisanje. Isporuka robe je preduslov urbanog života, a od efikasnosti logističkog sistema zavise poslovne aktivnosti kojima se ostvaruje bogatstvo i razvoj gradskih sredina. Ipak, logističke aktivnosti nisu poželjne u gradu. Realizacija robnih tokova ima negativne efekte na životno okruženje, bezbednost saobraćaja i narušava kvalitet života. Sa rastom populacije i ekonomskim razvojem urbanih sredina, rastu i problemi realizacije logističkih tokova. U cilju smanjenja negativnih uticaji i veće efikasnosti logističkog sistema, definišu se različite mere, inicijative i koncepcije city logistike. Rešavanje problema složenog sistem logistike grada zahteva obimna istraživanja, sveobuhvatnu analizu i integrisano planiranje. Cilj istraživanja je utvrđivanje parametara, performansi city logistike. Međutim, skup performansi i način utvrđivanja nisu standardizovani, a permanentno praćenje dela parametara predstavlja izuzetak prisutan samo u nekim gradovima. Usled nedostatka performansi, urbane vlasti i planeri nemaju kompletnu sliku logistike, a bez poznavanja postojećeg stanja nije moguće ni traženje efikasnog rešenja. Prilikom definisanja i izbora koncepcije city logistike neophodno je razmotriti karakteristike grada i ciljeve svih interesnih grupa. Gradovi se razlikuju po demografskim, geografskim, privrednim, ekonomskim, sociološkim, kulturološkim i istorijskim karakteristikama, pa inicijative i koncepcije city logistike nemaju iste efekte, a u nekim gradovima nisu ni primenjive. Osnovni problemi nisu uvek dobro definisani, a povezanost sa predloženim merama i karakteristikama grada nekad ne postoji, iako je to cilj. Sa druge strane, svi učesnici city logistike žele atraktivan grad po svim kriterijumima, ali su pojedinačni ciljevi najčešće u konfliktu. Opisani problem se rešava definisanjem velikog broja kriterijuma koji će u obzir uzeti sve zahteve i interese zainteresovanih strana i velikog broja faktora koji odražavaju karakteristike grada... City is a place with the highest concentration of people, economic and social activities, and logistics is exceptionally important for its functioning. Freight delivery is a prerequisite for urban life, whilst business activities generating wealth and development in metropolitan areas depend on the logistics system’s efficiency. And yet, logistics-related activities are not desirable in a city. Implementation of freight flows has an adverse impact on the living environment and traffic safety, and it also impairs the quality of life. With an ever-growing population and economic development of urban areas, problems in the implementation of logistics flows are further exacerbated. In order to reduce the negative impact as well as to boost the logistics system’s efficiency, a variety of measures, initiatives and concepts of city logistics are defined. Resolving problems in a complex system of the city logistics requires extensive research, comprehensive analysis and integrated planning. The goal of such a research is to lay down parameters for the city logistics performance characteristics. However, the set of performance characteristics and the manner in which they are determined are not standardised, whilst permanent monitoring of some parameters is an exception present only in some cities. Due to unavailability of performance characteristics, urban authorities and planners lack the logistics big picture. With no knowledge of the existing situation, it is not possible to seek out an efficient solution. When defining and selecting a concept of the city logistics, it is necessary to consider city characteristics and goals of all the stakeholders. Cities differ in terms of their respective demographic, geographic, economic, business-related, sociological, cultural and historical characteristics, hence initiatives and concepts of the city logistics do not bring about the same effects, and in some cities, they are not even applicable. Basic problems are not always well defined, and, at times there is no linkage with the proposed measures and city’s characteristics, even though this is the objective...
