This paper is dealing with the evolvement of operational research in logistics related to ITS projects. Basically a static model has been introduced by the authors. The model is an extended assigned method. There are more and more quasireal-time data existing on the changing properties of real world elements and processes due to the less and less c...

Closed transport systems have been widely implemented in various areas of bulk solid handling because of their advantages. The unique character of these systems stems from the fact that transported material is fully enclosed by a conveyor belt. To ensure their operational reliability and efficient maintenance during operation, processes occurring i...

The energy efficiency of transport systems consisting of several belt conveyors is significantly affected by re-direction. The proper sizing of several conveyor belts using deflector plates can significantly affect their efficiency. At present, there are no uniform rules (models) which specify the methodology and procedures for their design. This p...

Competitiveness of destination is determined by indicators that determine their ability to compete with other destinations. It places extraordinary demands on the compilation of such a measurement model for the competitiveness of tourist destinations, which could result in one specific number of pre-defined categorization of competitiveness that co...

Every manufacturing company is a major producer of activities and practices which have negative effect on the environment. One of the primary logistics activities of manufacturing process of enterprise which has a negative effect on the environment is intro-plant conveying. The paper analyzes and proposes a complex solution of calcined ore conveyin...

General business is becoming ever more reliant on logistics, its application fields and supply chain management. This is due to keep pace with the demands of an increasingly global economy. Business leaders know that the supply chain and effective logistics chains can be a value creator and also a source of competitive advantage. For realization of...

Wastes are created in all human activities and the problem of wastes reduction, elimination and also prevention of its production needs an adequate solution. One of the possible way to solve this problem is presented by reverse logistics and its processes. Reverse logistics is one of the application parts of logistics and it can be applied not only...

The paper interprets the calculation of the size of force effects created by the reason of the effect of balled conveyor belt of pipe conveyor to the guide rollers located in the ring idler stations. Knowing them is essential for the research of dynamic resistances by pipe conveyors operations. Examined force effects were determined by the help of...

Economic efficiency of road haulage is an important factor for all enterprises dealing with road haulage. One of the possible solution is presented by analysis of techno - economic parameters and subsequent solution which results from these parameters. The paper present a possibility of increase of economic efficiency in the specific enterprise dea...

Solution of problems in the field of ecology and environment has an important place at the state level, but also at the level of civil initiatives and individuals. It is in the result of increasing limitedness of natural resources and environmental consciousness. Eco-logistics is important effective tool which is the object of study, discussions of...

One of the most important role of all communities is to assure, create and take bearings to the effective support for non-profit sector, which is a very important element in providing of assistance in the cases when the help at the state level is not sufficient. On the present, non-profit organizations are experiencing their continuous development...

Reverse logistics is very interesting part of eco-logistics, application part of logistics. It creates conditions for various applications and also for various subjects. One form of application is connection of reverse logistics and processing of used wear conveyor belts. Conveyor belts present one of the most important parts of belt conveying and...

Options for further use of worn-out conveyor belts were analysed and examined within the frame of research about options of reverse logistics. Reverse logistics has importance because one of the most important elements of reverse logistics is presented by wastes. By the research it is examined the reverse logistics network system for wastes. The ar...

In this paper a new mathematical geometric model of spiral triangular wire strands with a construction of (3 + 9) and (3 + 9 + 15) wires is proposed and an accurate computational two-layered triangular strand 3D solid modelling, which is used for a finite element analysis, is presented. The present geometric model fully considers the spatial config...

One of the most frequently damage of rubber-textile conveyor belt is caused by sharp-edge material impact. The paper deals with study of process of irreversible changes formation in the internal structure of rubber-textile conveyor belt caused by sharp-edge material impact. The aim of the paper is knowledge of damage process which is required for t...

The most common case of conveyor belts damage is their puncture by falling sharp material. One of the ways, how to minimize this type of damage, is using of suitable type of conveyor belt. Therefore, the analysis of conveyor belts on the part of their puncture resistance is an important factor for their use in operation conditions. The aim of the p...

Damage of a conveyor belt by impact of sharp material is referred to as breakdown. By conveyor belt breakdown it occurs to perforation of its individual layers. Identification of this type of damage is relatively simple by the help of visual control. However in practice it often occurs due to the impact of sharp material to local anomalies that are...

The paper presents verification of the effect of emitted tension force of conveyor belt to the size of contact forces which are induced by the closed conveyor belt on the guide idlers in the hexagonal idler housing of pipe conveyor. The conveyor belt is an object with action of tension force and at the same time it takes the initiative in the conta...

This paper presents experimental measurements of selected properties of pipe conveyor belts, which are dynamically damaged. Apart from results of experimental measurements, new experimental analysis of inner structure of conveyor belt by computer tomography is used.The aim of the paper is to show the change of physical and mechanical properties of...

The analysis conveyor belts plays an important coal in both, the development of new types of belt conveyors (e.g. using new typs of rubber of reinforcement materials) and the determina- tion of the influence of operating conditions on conveyor belt wear and damage, and thus, life time. A number of different systems have been developed over the last...

Interaction of a pipe conveyor belt with moulding rolls is a very interesting problem for producers and also for users of pipe conveyors. There are created high resistances and deformations in this part of pipe conveyor. The determination of contact forces is difficult. The paper deals with problem of computation of contact forces generated by acti...

The base of logistics of crisis situation forms crisis planning which deals not only with the preparation and creation of forces and means for elimination of crisis situations results but also with analysis of risks, prevention, material flow control, financing and personal constitution of correct, prompt and quick operation of logistical system in...

The present time is characterized by high rate of motoring, and from this fact it results the necessity of frequented utilization of vehicles of different kinds of transport systems. Vehicles create a significant part of transport systems. It is possible to say that they are the most frequently used kind of vehicles in various industries. Automobil...

Assessment of optimal solution – alternative of layout is deeply wedded with material flow. For alternative design it is possible touse a combination of optimizing method for layout of workstations, triangular method and computer simulation by program EXTEND,whereby the simulation performs the function of accuracy of solution verification.
