Packaging also fosters effective marketing of the food through distribution and sale channels. It is of the utmost importance to optimize the protection of the food, a great quality and appearance - better than typical packaged foods. In recent years, intelligent packaging became very popular. Intelligent packaging is becoming more and more widely used for food products. Application of this type of solution contributes to improvement of the quality consumer life undoubtedly. Intelligent packaging refers to a package that can sense environmental changes, and in turn, informs the users about the changes. These packaging systems contain devices that are capable of sensing and providing information about the functions and properties of the packaged foods. Also, this paper will review intelligent packaging technologies and describe different types of indicators (time-temperature indicators, freshness indicators).

Background: European economies have been deeply affected by different crises. The impact of the economic crisis on enterprises is now recognized by everybody. Enterprises need to reorganize in order to be better adapted to this situation and to integrate new dimensions in their development. Reduction of cost is not the only way for making enterprises more efficient. It is now clear that a mono-criterion analysis is not adapted to the actual enterprise situation. Enterprises need a multi-criteria analysis by combining quality, cost, lead time but also carbon management, social societal and environmental dimensions. If QCD criteria are already considered as necessary for obtaining the optimum enterprise system, it remains difficult to convince the enterprise management of the opportunity to integrate social, societal and environmental dimensions for improving cost. This need still needs to be clearly demonstrated.
Method: This paper introduces concepts for showing that enterprises would be more efficient, better-organized and adapted to the new changes in society.
Conclusions: The reduction of cost is necessary, the increase in enterprise turnover too, but it is also indispensable to change the structure of enterprises. Enterprise modeling (GRAI Methodology) and a tool is used for illustrating the concepts presented through a detailed case study.

Background: Remanufacturing of automotive components is a developing sector. The majority of companies in this sector belong to the group of SMEs. The remanufacturing benefits to the circular economy concept. The used products referred as "cores" are in the remanufacturing process bring back to as good as new condition. Supply management of cores faces a number of problems, which are discussed in the literature but there is still a lack of empirical studies in this domain.
Material and methods: The research methodology consists of a literature review, where research papers from the Scopus, Science Direct and Business Source Premier databases were used. On the basis of literature review the problems are identified. The pilot survey was elaborated in order to get in depth knowledge on the organization of the cores' supplies in small and medium-sized enterprises (SMEs).
Results: The survey was conducted among 40 SMEs in automotive remanufacturing sector. The paper presents the characteristics of the respondents and it identifies sources of the cores supplies. Authors discuss also the main problems which appear by organization of these supplies.
Conclusions: A remanufacturing process is more complex than the respective production process. The cores' supply management is crucial for profitability of remanufacturing. This paper provides in depth view on the practical issues in the cores supply management regarding source of cores, quality problems, material matching restriction problems and high variety of cores.

Background: The integration, besides synergy and convergence, is regarded as a leading orientation in modern logistics. The connection of various participants within supply chains enables the integration of actions and allows to fulfill growing customers' demands in an effective and economically efficient way. In times of a concept of the balanced development, growing interest in utilization of recycled material, connected with possibilities to consolidate logistic activities, can be observed. According to the scientific literature (integration models) as well as practical business cases, supply chains of forward and backward type (two-directional) are the area of logistics of the intensive development.
Material and methods: The paper presents the Authors' model and methodology of modeling of the integration of supply chains, which realizes the flows of forward and backward type (two-directions). The empirical material was obtained during modeling and simulation of processes in the environment of iGrafx Process 2013 for Six Sigma with the support of Minitab 17 (for planning of experiments). The method of the verification of statistical hypotheses was used. As a first step, the correlation between the level of the integration and the global service level for the supply chain was conducted using the method of Pearson's coefficient. The test of relevance of correlation coefficient was conducted by the use of t-distribution method. Then the verification of statistical hypotheses was made, based on the method using the Z-statistics.
Results: The obtained results indicate clearly the strong relationship between the level of the integration of a supply chain and the obtained service level (values of Pearson's correlation coefficient and results of t-test). The detailed statistical researches of authors indicate that the increased level of the integration leads to the increase of the average value of service level coefficient (results of Z-statistics). Concluded, the analyze of the service level indicator shows its growth together with the growth of the integration level.
Conclusions: Based of integration aims, the integrated systems should have bigger possibility of activity. The possibility to obtain higher customer service level is one of postulated effects ("gains") of the integration of supply chains. The results of Authors' researches confirmed such statement in quantitative way, and not only in a describing one. The conclusions from conducted researches encourage to integration activities within supply chains of forward and backward type.

Background: For many logistics service providers and shippers sustainable transport is still a relatively recent issue, even if almost every transportation company is engaged in sustainability. Each has had different experiences with making transportation more sustainable. By looking at the efforts and successes of others sharing these experiences could help shippers and logistics service providers to obtain new innovative ideas of how to become more sustainable. The certification organization Green Freight Europe (GFE) wants to develop a database for these types of experiences in order to encourage its members to generate sustainable initiatives.
Method: In support of this plan, we interviewed several logistics service providers and shippers and conducted a brief survey among GFE members.
Results: Sustainability forms one of the goals for all interviewed companies mainly based on cost reduction but followed closely as a tool to attract new customers. At the moment, the information obtained to keep updated on sustainability comes mainly from truck producers and not from information from best cases from other logistics service providers.
Conclusions: We have found that there is a willingness to submit best cases, but also a fear that the submitter will miss his competitive advantage by telling others about his innovations.

AGH Krakow University of Science and Technology, Krakow, Poland
Background: The logistic systems are very complex socio-technical systems. In this paper the proposal of application of the hierarchical multi-layers system platform HILS approach for the solution of the complex vehicle routing problems is presented. The interactive system functional structure was proposed which by intelligent dedicated inter-layers interactions enables the professional solutions of these practical problems. To illustrate these capabilities the complex example of the real-time VRP-SPD-TW routing problem was presented in which upper layers offers the context-related real-time updating network specifications that stimulates the adequate routing parameters and specifications updating for problem solution in optimization layer. At the bottom dispatching control layer the DISCON (Dispatching CONtrol) method from public transport was adopted to logistics applications in which the actual routing is treated as obligatory reference schedule to be stabilized. The intelligence aspects are related among others to HILS based decompositio

Background: The article aims at presenting a study into disruptions in a network supply chain of metallurgic products. The research was carried out in the years 2011-2013. Network supply chains include key chain links for building the resistance. These chain links affect material flows of the whole supply chain through silencing disruptions. Those predisposed to form a strategy strengthening the resistance of the whole network supply chain are organizations fulfilling the assumptions of flagship enterprise.
Material and methods: The research is carried out in two stages: the stage of identification of disruptions (risk factors) and the stage of identification of strengthening disruptions zones. The authors carried out simulation experiments based on three models built in the management system dynamics technique (VensimDSS). The proposed methodology required constructing original tools for measuring disruptions and zones strengthening the disruptions in the form of cards for measuring disruptions.
Results: The value added is grouping of disruptions in risk factors distinguished in terms of the frequency of the occurrence of disruptions and their results. The authors proposed and defined the notion of zones of strengthening disruptions. The zones are formed from sets of factors strengthening disruptions with similar influence on disruptions.
Conclusions: The IT system composed of a module for identification of disruptions in material flows and a simulation model is a proposal dedicated to organizations controlling material flows in a network supply chain in the conditions of disruptions.

University of Economics in Katowice, Katowice, Poland
Background: One of major areas of modern research econnected with management issues covers inter-organizational networks (including supply chains) and cooperation processes aimed at improvement of the effectiveness of their performance to be found in such networks. The logistics is the main factor responsible for effectiveness of the supply chain. A possible and a quite new direction of research in the area of the performance of processes of the inter-organizational cooperation is the proximity hypothesis that is considered in five dimensions (geographical, organizational, social, cognitive, and institutional). However, according to many authors, there is a lack of research on supply chains conducted from the logistics point of view. The proximity hypothesis in this area of research can be seen as a kind of novum. Therefore, this paper presents the proximity concept from the perspective of the management science, the overview of prior research covering the inter-organizational proximity with supply chain from the logistics point of view as well as the possible future directions of the empirical efforts.
Methods: The aim of this paper is to present previous theoretical and empirical results of research covering inter-organizational proximity in logistics and to show current and up-to-date research challenges in this area. The method of the critical analysis of literature is used to realize the goal constructed this way.
Results: Knowledge about the influence of the inter-organizational proximity on the performance of supply chains is rather limited, and the research conducted so far, is rather fragmentary and not free of limitations of the conceptual and methodological nature. Additional rationales for further research in this area include knowledge and cognitive gaps indentified in this paper. According to authors the aim of future empirical research should be as follows: (1) unification and update of used conceptual and methodological approaches in research on the proximity in supply chains, (2) testing of theoretical hypotheses with attention paid to importance of the proximity for supply chains taking into account the significant heterogeneity of this form of inter-organizational cooperation, and (3) recognizing the role of the inter-organizational proximity for the practice of supply chain management and for the realization of the integration function of the logistics.
Conclusions: There is a shortage of scientific research (both in the theoretical and empirical dimension) explaining the importance of the proximity hypothesis for the performance of supply chains. Additionally, there are interesting gaps in existing scientific output, connecting the logistics output (effectiveness and performance of supply chains) and economic geography (the proximity hypothesis). Closing these gaps should increase our understanding of the supply chains performance and, therefore, this will be the area of further research of authors.

Strategic vehicle fleet management - the composition problem
Adam Redmer

Poznan University of Technology, Poznan, Poland
Background: Fleets constitute the most important production means in transportation. Their appropriate management is crucial for all companies having transportation duties. The paper is the second one of a series of three papers that the author dedicates to the strategic vehicle fleet management topic.
Material and methods: The paper discusses ways of building companies' fleets of vehicles. It means deciding on
the number of vehicles in a fleet (the fleet sizing problem - FS) and types of vehicles in a fleet (the fleet composition problem - FC). The essence of both problems lies in balancing transportation supply and demand taking into account different demand types to be fulfilled and different vehicle types that can be put into a fleet. Vehicles, which can substitute each other while fulfilling different demand types. In the paper an original mathematical model
(an optimization method) allowing for the FS/FC analysis is proposed.
Results: An application of the proposed optimization method in a real-life decision situation (the case study) within
the Polish environment and the obtained solution are presented. The solution shows that there exist some best fitted (optimal) fleet size / composition matching company's transportation requirements. An optimal fleet size / composition allows for a significantly higher fleet utilization (10-15% higher) than any other, including random fleet structure. Moreover, any changes in the optimal fleet size / composition, even small ones, result in a lower utilization of vehicles (lower by a few percent).
Conclusions: The presented in this paper analysis, on the one hand, is consistent with a widespread opinion that the number of vehicle types in a fleet should be limited. In the other words it means that the versatility / interchangeability of vehicles is very important. On the other hand, the analysis proves that even small changes in a fleet size / fleet composition can result in an important changes of the fleet effectiveness (measured for example by the utilization ratio).
