The purpose of this paper is to demonstrate that the application of lean approach in supply chain can act and influence the improvement of performances of the overall supply chain, as well as of all its participants. Some of the benefits which can be achieved by applying lean tools, methods and techniques, with minimal required investment, in supply chain are: reduced wastes, reduced costs, improved quality, faster delivery, and consequently increased supply chain profitability. In this paper, the comparison of traditional and lean supply chain is done according to different derived characteristics. The identification of comparative characteristics is done by desk research in combination with conversational research. The paper can serve as a basis for transforming existing supply chain into a lean supply chain.

This article presents a novel shortest path algorithm for connected networks with nonnegative edge weights. The worst case running time of the single source shortest path version of the algorithm is O( max(m,(vs))) where m is the number of edges of the input network and (vs) is the normalized eccentricity of the source vertex v s. The pseudo-polynomial nature of the time complexity is overcome with a simple speed-up technique. The proposed approach can be implemented on a wide class of shortest path problems. Approximate solutions can be easily maintained in the preprocessing phase. An experimental efficiency analysis shows that the proposed approach outperforms existing algorithms in total computing time. The proposed algorithm is efficient for all classes of networks and particularly for networks with small diameter.

Today, logistics and supply chain management is attractive and very demanding field for a professional career. The competences that the employers in this field require from employees continue to evolve and change. This paper aims to provide a longitudinal assessment of two studies of online ads of logistics and supply chain management jobs conducted in the Republic of Serbia. Both these studies used the same methodology of collected, coded and analysed job ads. The ads were analysed by deductive content analysis and related quantitative indicators. The aim is to reinforce the results of these studies by searching statistical similarities in professional and fundamental competences of logistics and supply chain managers. Also, several studies done in the US, the UK, Germany, Brazil, etc. will be used for drawing conclusions. The outcomes of this paper can be valuable to educators, to educational and professional institutions, and to other interested parties.

This paper examines the competences that the employers in the logistics and supply chain management (SCM) field require most from employees in the Republic of Serbia. To identify these competences, we conducted a study of online advertisements of logistics and SCM jobs published in the renowned national job portal Infostud. We used a deductive content analysis and related quantitative indicators to process and analyse the data. The results, among other conclusions, indicate the most required professional and fundamental competences from the logistics and supply chain managers in the Republic of Serbia. When the results of this study are compared to several earlier studies done in the US, the United Kingdom and Germany, some similarities between these empirically obtained results are found. Several recommendations for educators that intend to improve study programmes and plans in the field of logistics and SCM are also offered. The results of this study can be valuable to interested educators, to individuals who are interested in logistics and supply chain career development, to human resource managers who are recruiting candidates for these jobs, and to other interested parties.

The material requirements planning (MRP) is a traditional topic in operations management and industrial engineering education. This paper presents an application of custom-made selection procedure of MRP educational software. The results of evaluation from the three generations of students showed that the selected MRP educational software was very useful in acquiring advanced students' MRP skills.

Manufacturing cell formation is the first and foremost issue in designing cellular manufacturing system. The main objective in the cell formation problem is to cluster machines into machine cells and parts into part families so that the minimum of both intercell and intracell flows will be achieved. The purpose of this paper is to enhance solving the cell formation problem with the help of e-Learning tools in the educational environment. An efficient method and supporting tool for solving manufacturing cell formation problem are proposed. Therefore, the original similarity coefficient-based heuristic (SCBH) algorithm for solving the cell formation problem is presented. It incorporates the pure combinatorial optimization models for maximization the sum of similarity coefficients between machine/part pairs. Additionally, the LAYOUT tool is offered as a supporting tool for the SCBH. A comparative case study is conducted to validate the performance of the proposed SCBH algorithm and LAYOUT tool, and the results showed that their implementation is significant for reducing both intercell and intracell flows. The results of this work can be helpful for future or existing practitioners to become the real-world cell formation problem solvers.

The focus of this paper is on the design and application of a new original decision-making support tool for the selection of logistics and supply chain management (SCM) educational games. The design of a decision support tool for the selection of these games (hereafter, DST SLSCMG) was followed by a case study which demonstrates the application of the DST SLSCMG, and the evaluation of the use of the games. The proposed DST SLSCMG is based on the database of 55 identified logistics and SCM games and components, which enable performing a multi-criteria analysis. It is applied at an engineering school for the selection of the most suitable games for two logistics and SCM-related courses. The results of the evaluation of the use of the games showed that students were very satisfied with the games selected with the help of the DST SLSCMG. The new DST SLSCMG offered here can help interested educators to assess the available logistics and SCM games and select the most suitable ones.

The paper focuses on the selection, application and evaluation of games suitable to enhance teaching and learning processes in two courses related to logistics and supply chain management (SCM) at the Faculty of Organizational Sciences, University of Belgrade. The selection procedure of logistics and SCM games which incorporates the database of these games and a multi-criteria analysis are designed and applied. Based on requirements to support practicing the distribution requirements planning (DRP) a new game has also been designed. The outcomes of post-game evaluation have shown that students like playing logistics and SCM games and that playing these games helps them learn something they have not previously known. The results of this study are useful for both academics and practitioners interested in training and education of logistics and supply chain (SC) professionals.

The aim of this paper is to design a conceptual framework of e-maintenance based on a hybrid system approach, and to analyse its characteristics and the effects of the system on maintenance and business performances. The Interactive Electronic Technical Manual is recognized as an effective e-learning tool and the main maintenance-related component of the framework. The major benefits of the developed framework are an automated process of data entry, maintenance of data consistency, decreased data redundancy, and customised reporting. The proposed conceptual framework should be suitable for maintenance and logistics engineers who intend to develop e-maintenance in industrial sites.
