Abstract

On the basis of relevant scientific research this paper systematically and concisely elaborates the interaction between intellectual capital and logistic services production. Full attention is given to intellectual capital as a factor in effective creation of the logistic processes or in other words, to prove the statement that the first place for achieving competitive advantages in the global and/or regional market of logistic services belongs to knowledge used to produce or improve the existent logistic systems and to create new ones.Further, the paper deals with the tasks of creative logistic managers as open, dynamic and stochastic systems based on knowledge or the creation of universal logistic model determined by the fact that intellectual capital and technological paradigm create the way to new logistic paradigm.Special attention is paid to building and presenting a mathematical model for measuring the intellectual capital as well as the success of its use in different logistic companies. U ovoj se raspravi temeljem relevantnih znanstvenih spoznaja sustavno i koncizno elaborira interaktivnost veza intelektualnoga kapitala i proizvodnje logističkih usluga. Najviše se pozornosti posvećuje intelektualnom kapitalu kao čimbeniku efikasnoga osmišljavanja logističkih procesa, odnosno dokazivanju tvrdnje da djelotvorno uporabljenom znanju u funkciji proizvodnje i unapređenja postojećih, te kreiranja novih logističkih usluga, pripada primarno mjesto u stjecanju konkurentskih prednosti na globalnom i/ili regionalnim tržištima logističkih usluga. U nastavku se promišljaju zadaće kreativnih logističkih menadžera u funkciji izgradnje logističkih kompanija kao otvorenih, dinamičkih i stohastičkih sustava utemeljenih na znanju, odnosno kreiranju univerzalnoga logističkoga modela determiniranoga činjenicom da intelektualni kapital i tehnološka paradigma kreiraju put novoj logističkoj paradigmi. Posebna se pozornost u ovoj raspravi posvećuje izgradnji i prezentiranju matematičkoga modela u funkciji mjerenja veličine intelektualnoga kapitala i uspješnosti njegova korištenja u različitim logističkim kompanijama.

Abstract

This work proposes a method to improve the flexibility of short sea shipping and to increase its competitiveness with other means of freight transport. A logistic model and a mathematical model are developed to manage a fleet of two or more vessels which transport cargo to and from several ports, bearing in mind the cargo distribution and delivery deadlines. At each port, the model determines which port to visit next, which containers to embark, disembark and to shift, as well as how to stow them on board. In fact, this formulation brings together the fleet management problem, the container stowage problem (CSP) and the vehicle routing problem (VRP). An example scenario is set up, using generated but realistic data. The problem is then solved, in a simplified version, using a Genetic Algorithm. The results show that introducing the possibility of route changes, the overall efficiency (and thus competitiveness) of short sea shipping can be improved.
