Application of an electronic bulletin board, as a mechanism of coordination of actions in complex systems - reference model
Katarzyna Grzybowska
1
Poznan University of Technology, Poznan, Poland
Background: In her previous research, the author of this publication indicates that coordination is a dependent variable which has a great driving force and is a very unstable factor. This results in the fact that all of the actions connected with coordination have an impact on other factors of cooperation as well as the integration of the enterprises in the structures of a supply chain type structure.
Material and methods: The article has been divided into two basic parts. The first part regards the reference models in complex systems (supply chain systems). They can constitute a starting point for the modelling of target processes in the built supply chain structure. The second part presents template process models (Reference Models) for selected action coordination mechanisms during enterprise cooperation. The aim of the article is the presentation the model an Electronic Bulletin Board (EBB), as a mechanism of coordination of actions in complex systems.
Results: The article was prepared on the basis of literature from the researched area. The material was also prepared on the basis of interviews with practitioners. They have allowed for the preparation of template process models (Reference Models) for selected action coordination methods in the supply chain.
Conclusions: The result of the work is a prepared model as well as its description in the use of IDEF0. The presented model is a demonstrative model. The proposed reference model makes it possible to define the parameters of a selected mechanism of coordination of actions, and forms a basis for affecting the progression of the process through an analysis of values of identified parameters. The parameterization of elements constitutes the foundation for the monitoring of the process via 1) unambiguous identification of the object of monitoring and 2) analysis of different variants of the progression of the process.

Background: Integration trends are one of main determinants of the development of modern logistics. After the period of interest focused mainly on supply chains realizing one-way flows only, at present there is a time for supply chains characterized by two-way flows, realizing at the same time both forward and backward flows. The possibility of various configurations of such chains requires identification of integration factors and determination of their influence on the results of the whole supply chain. Experiences of the science as well as the practice of supply chains show the urgent need of learning of reasons of the integration within supply chains of the two-way type.
Material and methods: The researches on modeling and simulation of integration processes within supply chains of forward and backward type were carried out in the environment of iGrafx Process 2013 for Six Sigma. The empirical material obtained in these researches was put to the statistical analysis by the used of Minitab 17. The identification of the significance of differences was made with the help of analysis of variance ANOVA. Additionally the analysis of differences in form of absolute averages was made. The following measures are main ones for the evaluation of the integration of a supply chain of forward and backward types: cashflow, profitability, service level.
Results: 8 192 simulation experiments were made for 6 integration factors: accessibility of recycled materials, production planning, stock management, integration of transport, unification of packing materials and optimization of the material flow. Based on the analysis of the significance and values of differences, the results of the influence of each integration factor on global results of supply chains of forward and backward type were obtained. They were used to prepare the ranking of integration factors. The main factors, forming the integration shape of two-way supply chains were: stock management, production planning and accessibility of recycled materials.
Conclusions: The integration offers new possibilities therefore it is the promising option of actions. In complicated and complex logistic reality, it is more and more difficult to function, in economic sense, without starting and tightening close cooperation. Sometimes it is even not possible at all. The growing popularity of two-way supply chains opens the dimensions of the possible cooperation. However, both science and the practice need the reliable quantitative information covering the conscious creation of the integration in supply chains. Such tool could be a ranking, recommended in this paper, of integration factors from the perspective of three measures of evaluation of global level of functioning of the supply chain.

Division of environmentally sustainable solutions in warehouse management and example methods of their evaluation
Wiktor Żuchowski

The Institute of Logistics and Warehousing, Poznań, Poland
Background: Environmentally sustainable solutions are entering the domain of logistics. More and more frequently do we hear of sustainable or "green" warehouses, although the scale and scope of implementations in specific investments is not incomparable, and the adjective "green" is added rather for marketing, not utility-related, purposes. Furthermore, it is difficult to confront implemented solutions differently than with the use of evaluations dedicated to broadly-understood sustainable buildings. In order to identify the solutions, it is necessary to prepare a key for their division first. Identification, classification, popularisation and, in the long-run, implementation of sustainable solutions in warehouse management requires them to be organised.
Methods: On the basis of available information, chiefly primary and secondary sources, but also legal documentation developed in countries with high environmental awareness, materials which allow indicating the structure of division of sustainable solutions have been collected. The division has been prepared by means of analysing solutions, creating homogenous groups, and their further unification. The comparison of evaluations given to sustainable solutions has been prepared on the basis of information made available by certifying institutions.
Results: Sustainable solutions have been divided into groups, although the division is not disjoint. Three basic groups of solutions (reducing harmful emissions, reducing consumption of resources, increasing ecological value of facilities) have been distinguished. One is homogenous, the other two are divided into further subgroups.
Conclusions: Division of sustainable solutions and specification of particular groups are a basis for identification, qualification, popularisation and, in the long term, implementation of sustainable solutions for warehouse management, consequently leading to lower emission of greenhouse gases and resource consumption, and, in the long-run, to a "green" warehouse.

Fuzzy Decision-Making Approach in Geometric Programming for a Single Item EOQ Model
Monalisha Pattnaik
1
Utkal University, Bhubaneswar, Odisha, India
Background and methods: Fuzzy decision-making approach is allowed in geometric programming for a single item EOQ model with dynamic ordering cost and demand-dependent unit cost. The setup cost varies with the quantity produced/purchased and the modification of objective function with storage area in the presence of imprecisely estimated parameters are investigated. It incorporates all concepts of a fuzzy arithmetic approach, the quantity ordered, and demand per unit compares both fuzzy geometric programming technique and other models for linear membership functions.
Results and conclusions: Investigation of the properties of an optimal solution allows developing an algorithm whose validity is illustrated through an example problem and the results discu ssed. Sensitivity analysis of the optimal solution is also studied with respect to changes in different parameter values.

The University of Dąbrowa Górnicza, Poland
Background: The changes which are taking place today, forces companies to ask themselves about the quality of leadership in the organization and whether the existing work in this area supports the success of the company. In the global environment, both social structure and political are changing. Demographic changes irrevocable impact on the market more than ever before. For company it is necessary to introduce new paradigms of leadership to have a chance to succeed in this new environment.
The aim of researches was to recognize methods, which allow to improve the quality of management of transprot companies.
Methods: Researches were conducted based on literature review and questionnaires sent by employees.
Cocnlusions: Leadership agility model seems to be the answer to the question of how to survive in the new world. Concept of leadership agility draws attention to a smooth transition between the different management styles as well as the end of the heroic leadership, (focused on only one leader) and the beginning of the post heroic leadership, where the contribution of the whole team count. In the new environment, a significant part of the company's success will depend on the commitment of its employees, and hence the added value of their work. Model of leadership agility is used in DHL Express daily and build the base for achieving excellent results not only business but also those related to human capital.

The role of the concept of corporate social responsibility in building relationships in the supply chain
Maciej Urbaniak

The University of Lodz, Lodz, Poland
Background: The aim of this article is to determine the importance of the concept of corporate social responsibility in building partnerships in the supply chain.
In the recent period, one could notice that more and more international companies implementing their strategies based on the concept of sustainable development are evaluating and qualifying their suppliers basing on standards of ethics in business.
Methods: This paper analyzed the requirements of the multinationals companies towards their suppliers in implementing elements of the concept of corporate social responsibility.
Results: The results of the analyzes which were presented on practical examples show that buyers define to suppliers, very often detailed, standards for ethical conduct for suppliers (Supplier Conduct Principles, Principles and Standards of Ethical Supply Management Conduct) and guides for their implementation (Supply Chain CSR Deployment guidebook, Purchasing Way, Supplier Sustainability program Manual), organizing programs (Supply Chain Social Responsibility programs), implementing the Supplier Responsibility projects and developing a checklist (Supply Chain CSR Checklist) for self-evaluation of providers.
Conclusions: When observing global trends one could notice that recently more and more suppliers are evaluated in terms of the fulfillment of the principles of sustainable development, guided by the economic aspects (requiring high technical quality, reliability of supply, competitive price, stable financial position, compliance with legal requirements), environmental aspects, as well as social aspects (principles based on the idea of the Global Compact). One could also perceive that many international companies signing contracts with suppliers require them to sign a declaration, obligating them to introduce the concept of corporate social responsibility by applying the principles contained in Statement on Business Practices and in compliance with the requirements of environmental requirements (Supplier Social & Environmental Responsibility Agreement).
