Quality Indexes of Warehouse Services
1-13Views:436There was a wide range and rapid development in the field of warehouse management in the recent decades as a result of strong and spectacular improvement of establishing and operating warehouses, in addition to increasingly complex logistic processes. In my research, I analysed the complex problems of determining the performance expectedfromoperatingthewarehousetechnologicalsystem. Thisdecisioninvolvestheselection of the essential performance indicators suitable for performance measurement and the determination of the expected performance level based on these indicators through the example of an examined enterprise. During my research, I concluded that the logistic performance measurement of warehouse processes is a very difficult process, because all enterprises have to define and use indexes which adapt to the enterprise profile well and reflect the performance to be measured. This decision is of key importance, since the warehouse system and its operation principles have to be adjusted to this expected performance.

Selection of Possible Installation Sites for Sour Cherry Refrigerated Containers and Estimation of Container Volumes to be Installed Using GIS Tools
108-115Views:30The purpose of this study is to propose the selection of installation sites based on publicly available data and sour cherry refrigeration container specifications, as well as to estimate the number of containers to be installed at possible sites. Today's escalating fuel supply and fuel price extremes make it particularly important to develop a sensible logistics sub-solution in the complex process of production, harvesting, storage, processing and sales. We undertook to develop a geospatial system that can be built and operated economically, its data sources can be updated occasionally or even at regular intervals, it is suitable for producing other outputs with additional descriptive or spatial data.

Simulation of production processes with Plant Simulation
10-16Views:131This article presents the modelling of interconnected companies’ logistic processes with Tecnomatix Plant Simulation by Siemens. It has two main parts. The first contains the details of recognition including simulation. The second part presents the modelling with Tecnomatix Plant Simulation. My publication is supported by the EFOP3.6.1-16-2016-00022 project. The project is co-financed by the European Union and the European Social Fund.

Determination of the accumulation of heavy metals of river sediment by plants
46-53Views:112Danube is the main river of Hungary. Danube and its floodplains and oxbow lakes are operating as ecological corridors, although their industrial, logistic and touristic role is not negligible. It is well known, that from the source to the estuary of the river Danube there are many industrial facilities. This heavy industrial pollution had effected on the water quality. The most dangerous components of the sewage water of these facilities are heavy metals, which can be found in the water as well as in the sediment. These toxic elements can cause significant health risks, because they can accumulate in the food-chain. The main aim of our research is to investigate the accumulation rate of the heavy metal content of the river sediment in the different parts of the test plants. The main sampling place of our research was a sediment dump was created by excavation from the Open Beach of Dunaújváros in 2009. During our measurements we analysed the cadmium, nickel, lead, chromium, copper and zinc concentration of the sediment and the plants. The test plants, which are growing on this sampling place, were parella (Rumex patientia), perennial rye-grass (Lolium perenne), sedge (Carex riparia), bistort (Persicaria maculosa). The extraction of the heavy metal content of the samples was made according to the MSZ Hungarian standard. The concentration of heavy metals were analysed with AAS (atom absorption spectrometer). According to our results we determined that parella could accumulate cadmium, nickel, chromium and zinc in its upper stem, on the other hand bistort could accumulate these elements mainly in its leaves. These information will be important in the case of the in-situ remediation of a polluted area in the future.

Physical Internet – a Novel Application Area for Industry 4.0
152-161Views:169The Physical Internet (PI or π) is one of the most decisive ideas for future logistics systems. The idea behind it is to implement logistic systems which apply the principles of Internet information flow. Simultaneously technological innovations of Industry 4.0 have also appeared. Our current research deals with the applicability of the tools of Industry 4.0 technology in the PI system. Following the literature review we analyse the individual technological tools that could improve the functioning of PI components. Subsequently we will detail the usability of a specific Industry 4.0 tool and finally determine the future research steps.

Exploring the Role of Emotions and Moods in Decision Making: Study on the Use of Structured Decision Approach and Intuition
140-149Views:325Emotions and moods can play a significant role in the decision making. The present paper contest this point by providing evidence on the two important approaches used in decision making that is structured decision approach and intuition. For this purpose data was gathered from 150 respondents in two different groups. Chi square test, independent sample t-test and logistic regression analysis were used to test the hypothesis. The results of the study reveal that individuals with positive and negative mood state vary significantly in their use of structured decision approach and intuition. The individuals with negative mood state are more likely to use all steps of structured decision approach as compared to the individuals in the positive mood state. The results of the study further reveal that the individual’s emotional state significantly predicted the use of structured approach and intuition in decision making.
