It is known that the small commodity markets are influential to people’s life, but their operations are unique. The lack of standard management has become the biggest obstacle for the development of logistics services in a commodity market. How traditional logistics model can be operated effectively in a commodity market is therefore interesting in this study. The purposes of this thesis are to characterize the commodity logistics systems, identify the challenges of logistics systems in the commodity market, and discuss how the use of e-business platform may improve the logistics system. In order to realize the purposes, the qualitative approach was used in this research. Literature review, interview and case study in one Chinese city with a big commodity market are implemented in the research. Survey study has been carried out to collect data for analyzing the logistics systems. As the main results in this thesis, small-volume, short-life cycle, variety and variability are found to be the main characteristics of a logistics system in the commodity market in the case city. The challenges are therefore about how to design and improve the logistics system so that it can adapt to these characteristics. Finally, this thesis presents the analysis on how an e-business platform can provide effective solutions to meet these challenges.

Mokslinė literatūra leidžia teigti, kad kuriamos UAB „Riminta“ logistikos sistemos tikslas yra mažinti išlaidas ir transporto kaštus bei didinti įmonės pelną. / Logistics – one of the basic functions in business field. In global and rapidly developing market, where the speed becomes essential element of success, to compete effectively can only those who manage to deliver proper amount of production outright and on time. How to make certain the articulateness of this process along with the efficiency of the whole business when you face the problems in labour market and you are dependent on the many other link members? Exploring and analizing the logistic conception of UAB “Riminta”, it is necessary to foresee practically which direction should the activity move that it operate normally and met the requirements. The analysis show that international transportation, expedition and the activity which requires to deliver the product to the final purchaser is necessary to be filled. Science literature allows to state that the objective of the UAB “Riminta” developing logistics system is to reduce the expenses and the cost of transport and to increase the company’s profit.

The purpose of this dissertation is to provide an effective approach to design the supply chain (SC) of the cellulosic biofuel industry in order that it will support and accelerate the successful commercialization of the cellulosic biofuel industry. The methods of approach to this problem are (1) to assess the state-of-the-art biofuel SC studies, (2) to provide a decision support tool based on a mixed integer programming (MIP) model for the cellulosic biofuel supply chain design problem (BSCP), (3) to devise an exact solution method to solve large-scale instances of BSCP, (4) to evaluate a biomass logistics system based on biomass modules, by using new simulation elements for new machines, and (5) to compare several biomass logistics systems based on biomass module, bale, and silage, using simulation models. The first part of this dissertation broadly reviews the literature on biofuel SCs, analyzing the state-of-the-art biofuel and petroleum-based fuel SC studies as well as relating generic SC models that have been published over the last decade to the biofuel SC (An et al., 2010a). The resulting analysis proposes fertile opportunity for future research to contribute to improving biofuel SC. The second part of this dissertation formulates BSCP as a MIP model, which is a time-staged, multi-commodity flow, network design problem with an objective of maximizing profit (An et al., 2010b). The model prescribes strategic level decisions (i.e., facility locations, capacities, and technology types) as well as plans for transportation routes and material flows (i.e., quantities produced, stored, and transported) in each time period. A case study demonstrates managerial use in application to a region in Central Texas. The third part of this dissertation provides an exact solution method to solve BSCP. An embedded structure can be transformed to a generalized minimum cost flow problem, which is used as a sub-problem in a CG approach. This study proposes a dynamic programming algorithm to solve the sub-problem in O(m), generating improving path-flows. To accelerate branch-and-bound (B&B) search, it develops an inequality, called the partial objective constraint (POC), which is based on the portion of the objective function associated with binary variables. The fourth part of this dissertation evaluates a biomass module system, which is a conceptual logistics system based on large packages of chopped biomass with sufficient size and density to provide maximized legal highway loads and quick load/unload times. The last part of this dissertation evaluates economic benefits of the biomass module system, comparing it to bale and silage systems.

With focus on simulation studies, the present work aims to model and simulate a logistic system of a port terminal, whose specialization is the containers movements. Six scenarios have been developed in order to assess the resources needed to handle a specific volume of containers by a unit of time. The model is built in the software ARENA and the analysis of results was performed through common indicators in container terminals. These indicators were analyzed for each of the scenarios developed and finally evaluated the installed capacity for each of the scenarios. For de model validation were built two scenarios and for the other four sceanrios assessed how the resources of three berths for ships, 6 ship to shore, 6 rubber tyred gantry, 11 reach stackers, 26 trucks, 4 gates, 1 scanner and 30 inspection slots behaves with 440.000 container/year and 660.000 container/year.
