Testing Methods of Green Supply Chain, in Particular Supplier’s Selection an Evaluation Tools
240-254Views:419Today, more and more articles have emerged in the field of sustainability and sustainable development. Sustainability plays an important role in supply chain management too. Green Supply Chain Management (GSCM) has emerged as a key approach for enterprises seeking to make their businesses environmentally sustainable. The notion of GSCM implies the insertion of environmental criteria within the decision-making context of the traditional supply chain management. Enterprises are increasingly expected to extend their sustainability efforts beyond their own operations to their suppliers and customers to their sustainability expectations. Literature of green supplier evaluation and selection methods number is large, though the number of environmental factors are relatively limited. Recently in supply chain management decision making, approaches for evaluating green supplier performance have used both qualitative and quantitative environmental data. Given this evolving research area, the purpose of this article is to analyse research conducted in international scientific journals focusing on the selection and evaluation of a green supplier. The purpose of this article will answered two questions: Which selection methods are commonly used? What environmental and other selection criteria for green supplier management are popular?

Sustainability, sustainable supply chain management
322-328Views:880With the rapid development of the world economy, the growing scarcity of natural resources and the degradation caused by pollution, environmental protection has become a major concern for countries and regions of the world. Sustainability is a common subject in many parts of the world and the various research areas among policy makers, journalists, scientists, universities and social debate. It is generally accepted, that companies also play an important role in addressing the challenges of sustainable development. In this role, making a key challenge to balance often conflicting pressures caused by sustainable development, that is, the level of corporate economic performance against environmental deterioration and social disruption. Effective integration of sustainability principles into companies requires action beyond the borders of organizations. The issue of sustainability is becoming more and more prominent in corporate governance. One of the most important area of supply chain management is for companies to gain a competitive edge in the market. This has a significant impact on the natural environment, and there is a growing need to integrate environmental thinking in supply chain management and processes, which is why companies are increasingly focusing on sustainable development, taking on more CSR initiatives and achieving a greener supply chain. Sustainable and green supply chain management practices have been developed over the past decades, trying to integrate environmental considerations into organizations by reducing unwanted negative consequences for the environment of production and consumption processes. In this article, I have examined the issues of sustainability and sustainable supply chain management, mainly based on descriptive secondary literature.

Long Container Dwell Time at Seaport Terminals: An Investigation Study from a Consignee Perspective
Views:498Many companies are concerned about the problem of increasing average dwell time for their import containers at the port of the final destination and therefore incurring additional shipping costs in form of demurrage charges for the port administration and detention charges for the shipping line. Previous studies have addressed this topic by analyzing terminal operations and evaluated its effects on port productivity and competitiveness; however few studies have explicitly explored long container dwell time causes from a consignee perspective. This research aims to identify the causes of long dwell time for the import containers at port storage yards for one of the leading FMCG companies in Jordan. To that end, the data of import containers whose stay at the terminal exceeded the free storage days in the period between 2019 and 2020 were collected by referring to the set of shipping documents and reviewing the correspondences between the consignee and other parties in the supply chain. Based on the timelines that have been analyzed for each case of delay to the collection of shipping documents in consideration with the payment terms, as well as the clearance and delivery timelines, ten causes for the long container dwell time have been identified and classified into three main categories according to the types of flow in the supply chain; five causes related to information flow, two causes related to cash flow, and three causes related to physical flow. The impact of these causes has been evaluated using the demurrage and detention charges as a measure indicator and the findings of this research have also revealed that the causes related to cash flow have a greater impact than the other types of causes.

Role of Lean and Agile Supply Chain Models for Pellet Fuel Technologies
119-130Views:165Business organisations constantly strive to improve their processes, both internal and external. Within the supply chain of a product, different strategies can be applied. This paper aims to answer the basic questions like what is the core of lean and agile SCM strategies, what are the differences of the two models, and how can they be combined. This paper examines further, which of these SCM models and what elements of them can be applied for wood pellet supply chains, also examining the possibility of their combination. The result of these examinations is, that even though fuel pellets can be considered as simple commodity and not a very innovative product, diversity in input characteristics, optimization of fuel pellet technology process variables and changes in output market qualities and quantities need sometimes agile, flexible answer from pellet fuel SCM. The basically lean character of pellet fuel technologies and SCM can further enhanced by implementing agile SCM model elements, as is the increased integration of suppliers into the supply chain.

The research examined the state of art of digitalization readiness, focusing on I4.0 technologies, which supports the management to operate more efficiently the enterprise and to make better decisions. So the focus was on integrated enterprise information systems, management support systems, business intelligence systems, industry 4.0 technologies, and issues related to their application. The analysis based on an online questionnaire survey the request sent to 4.600 enterprises, the response rate was 5% which was representative of the branches of production, covered the Hungarian food and beverage manufacturing sectors in 2019. The companies were asked the most critical technologies in development, going towards Industry 4.0. The research tools were LimeSurvey, Mailing List Server, Excel, Power BI (Desktop, Publishing Server to distribute the results). The used analysing methods were making calculations, pivot tables, models, dasboards. We found that a significant portion of businesses, 78 %, use mobile devices in the manufacturing process. The three most relevant digital technologies are geolocating (GPS, GNSS), cloud computing, and sensor technology. The current level of digitalization and integration cannot be said to be high, but respondents are very optimistic about expectations. Improvements are expected in all areas in the next 2-3 years in terms of digitalisation and integration. Vertical integration involves, first and foremost, cooperation with partners in the supply chain. Horizontal integration means close, real-time connectivity and collaboration within the company. Unfortunately, between 6% and 15% of SMEs (approximately 9% on average) and large enterprises, 36% have a digital strategy. According to the survey, the sector needs significant improvement and creating a digitalization strategy.

Flexibility Analysis Of Inventory Cost Model With Ergonomics
166-173Views:152The economic and environmental sustainability issues in supply chain management have integrated by many researchers in the past decades. The ergonomics as a social aspect of sustainability had received a little attention by researchers. Therefore, the aim of the paper is analyzing the flexibility of developed inventory cost model with relaxation allowance and endurance time as a social aspect of sustainability. The effects of distance, unit weight of item and total number of items on relaxation allowance, the total cost of logistics operation and the EOQ model were investigated. The analyzed mathematical model was a single operator-single material model which covered transportation of fixed amount of raw materials from storage plant to production plant by manual material handling with simple cart and picking, storing, pushing and pushing back with empty cart for manual handling of the products. The different parameter values applied for analysis such as total amount of handled items (Q) changes between 500 pcs to 2750 pcs, unit weight of item (w) changes between 0.1 kg to 1 kg, distance of movement by manual material handling for picking and storing motions (d1) changes between 2 m to 3 m and the distance between the storing equipment and the supermarket of the production line for pushing motion (d2) changes between 15 m to 20 m. The results of the analysis indicated that the longer the distance of movement for all motions leads to decrease in savings of the model compared to EOQ model. The increase in unit weight of item is increase the savings obtained from application of our model and decrease the optimal lot size. There was no specific change on savings or optimal lot size as the total amount of handled item is increase. The compared results indicated that an increase in d1 and d2 lead to an increase in optimal lot size and increase in total cost of the model. Consequently, the analysis has shown that a decrease in lot size would be the better way to improve both ergonomic conditions and total cost of production in any different parameter values. Finally, the analysis of the inventory model with ergonomics were proved that this model is suitable for different industrial practices.

The Role of Stocks in the Supply Chain
515-526Views:1168Az ellátási lánc teljesítményét nagymértékben befolyásolja a szereplők készleteinek összetétele, nagysága, rendelkezésre állása. A végső fogyasztókért vívott versenyben kiemelt szerepe van a kiszolgálási színvonalnak, hiszen az ellátási láncok ugyanazokért a fogyasztókért vívnak versenyt, és a fogyasztók döntése leginkább e két tényező, mint a készlet nagyága és a kiszolgálás minőségétől függ. A tanulmány a kkv-k logisztikai problémáit feltáró kutatás része, melynek célja rávilágítani a jellemző nehézségekre, és azokra a kihívásokra, amelyek legtöbbször elkerülik a logisztikai- vagy ellátási lánc vezetők figyelmét. A fejlődő kkv méretű vállalkozások versenyképessége - ami magába foglalja a költségek nagyságát is, kapcsolódva a K+F tevékenységhez vagy vállalat növekedéshez – a lekötött tőke mértékével arányosan változhat, melynek jelentős részét képezik a készletek. A kutatásban résztvevő vállalat, a Diego Kereskedelmi Kft. készletezési politikáján keresztül kerül elemzésre a készletek összetétele, illetve a velük kapcsolatos kockázatok, illetve félreértések. A tanulmány célja továbbá a helyes megoldások elősegítése, melyhez szorosan kapcsolódik (az itt tárgyalásra nem kerülő) Lean megoldások támogató szerepe.

Practical Application of Methods in Strategy-Based Analyzes
59-72Views:490Increasing environmental volatility is a growing challenge for companies and businesses. The speed of economic events is changing, and the risk of uncertainty is increasing, requiring business to take a new approach to strategic planning. In the design and forming of their strategy, both the factors of the external and internal environment and the analysis of their competitors can be based on well-chosen methods. We consider the review of these methods, their application in planning and educational practice. The aim of our work, in which we present the methods that underpin the strategy applied in both domestic and international practice. The analysis of the external environment illustrates the construction and applicability of an external factor analysis matrix based on traditional PEST analysis and the Porter's five-factor model. In the case of internal factor analysis matrix, we focus on the approach of method choice, and on the applicable methods, the importance of the resource-based approach, the analysis of key factors and the Porter value chain analysis matrix. The third pillar of the analysis that underpins the strategy is the matrix-based assessment of competitors. The applicability of the methods depends on the form of the enterprise, the field of activity and the nature of its activities, which is complicated by the emergence of new economic spheres (e.g.: sharing) and transformed power relations.

Application of Nanomaterials in Food Industry and Agriculture
116-126Views:160Nanomaterials have unique application features which can mainly be associated with their size properties. These materials have much higher surface than the normal particle size variant of the same materials. Due to these properties, nanomaterials are widely used in the industry. Food industry and the agrarian sector are using these materials increasingly. The main goal of nano size components and additives are the improvement of some parameters of the food manufacturing process, the elongation of the best before date of the food and the improvement of the texture, stability and the consistence of the food. Probably, nanomaterials will play an important role in the development of the food industry, moreover, it can be anticipated that nanotechnology will also appear there and will influence the whole food chain. It should be noted that food industry is using several nano size class materials which are not referred to as nanomaterials. Some examples are the micelles of some proteins, like milk protein, and fatty acids. Considering all these, the aim of our work was to present a thorough review and summary of the current applications.

PDCA – How does the Organization Learn?
1-9Views:468An organisation (whether it is in the private or in the public sector)knows where it is headed, it has a vision. To achieve this vision the organisation can have a strategy beforehand or the vision can be the result of a continuously improving strategy.The strategy can be developed according to the earlier routines or in a totally new way. Many times failures help to find a solution better than the chain of successes. The lessons learned should inevitably be part of the following cycles otherwise the same issues rise again and again which finally ends in exasperation and giving up. When we create a learning process it is easier to focus on avoiding the obstacles than motivation. PDCA is a well-known method for it but what prevents us from applying it the proper way? What are the obstacles that prevent the organisation from developing through its learning processes?

Laboratory investigation of the rediffusion of contaminants originated from the aquiclude
232-238Views:117Many organic pollutants are released into the soil and thus into the groundwater due to anthropogenic effects (a chain of harmful human activities). Layers with low permeability (e.g. clay) play an important role in blocking the path of these contamintants. However, due to their sorption and diffusion properties, such aquiclude layers can also serve as long-term sources of contamination. Once the layer is contaminated, it is already very difficult to recultivate, and there is a potential for the pollutant to spread to higher permeability layers by slow diffusion processes. This phenomenon is defined as a so-called rediffusion process, in which contaminants are retransferred from the aquiclude to the layer with higher permeability. The purpose of this study is to demonstrate the possibility of modeling this rediffusion process in a laboratory scale and to quantify the effect of influencing parameters on pollutant transport.
