Can IoT be Used to Mitigate Food Supply Chain Risk? (pp. 43-48)

Ivan Beker, Milan Delic, Stevan Milisavljevic, Dusan Gosnik, Gordana Ostojic, Stevan Stankovski

The Internet-of-Things are new, but extremely promising multiple technologies that will revolutionize food supply chain and the way we are selecting and buying food. Combination of ubiquitous cell-phone usage, ability to “communicate” with food packaging and transfer specific information regarding risks immediately at the any point on the globe is offering much higher standard of consumer safety.

Managing Innovation: Are Project Management Methods Enemies or Allies (pp. 31-41)

Danijela Ciric, Bojan Lalic, Danijela Gracanin

To achieve the long-term competitiveness companies are invited to a continuous process of innovation. When talking about innovation we are dealing with opportunities that offer the promise of new growth platforms. This high impact level comes with a set of challenges which lead us to the question how to build innovation capability and make these processes more manageable. Innovations are today mostly implemented through projects that require divergent thinking, willingness to devote resources to projects which are likely to fail and these seem incompatible with project management thinking involving the enforcement of strict standards most corporate cultures embrace. To address this problem, the paper examines whether project management methods are obstacles and constraints or can be used to make this process be more reliable instead of high-risk varied attempts of trial-and error. It is shown that it is of utmost importance to find the best fit between innovation project characteristics and project management approach. An overview of the state of the art about this matter is given.

A Management Trinity: Employee Satisfaction, Customer Satisfaction and Economic Performance (pp. 25-30)

Luis Miguel Ciravegna Martins da Fonseca, Ricardo Lopes Ferro

Management and Total Quality Management Theories support the importance of employee satisfaction and customer satisfaction for companies economic results and ensuring success. However, there are still some gaps concerning evidence of relationships between these three constructs. This research aims to access if there are indeed positive relationships between employee satisfaction, customer satisfaction and companies economic performance. By using a large database from a Portuguese Official Agency, framed according to the EFQM Business Excellence Model, with inputs of small and medium companies in stable industries over 10 years, 3 hypotheses were statistically tested. The results support the propositions of valid relationships between EFQM Model results criteria with evidence of positive relationships between employees satisfaction and customer satisfaction and economic performance, and between customers satisfaction and companies economic performance, which is relevant both from a theoretical and practical point of view.

Theory of Constraints (TOC) Production and Manufacturing Performance (pp. 15-23)

Roberto Panizzolo

This paper is based on an empirical study of the relationship between Theory of Constraints (TOC) production and operational performance in manufacturing plants. The study uses a survey questionnaire to collect data from a sample of 61 European firms which have implemented the TOC approach. Analysis of variance (ANOVA) technique and regression models have been employed to test the research hypotheses. The results detect many differences and similarities in adoption of TOC practices across the countries and suggest that manufacturing managers should consider adopting some TOC practices instead of others. In particular the Drum-buffer-rope methodology, the development of a Master Production Schedule based on constraints and the use of Non-constraint resources with excess capacity are among the most important practices to enhance competitive performance of manufacturing plants.

Review on Optimization of Hole-Making Operations for Injection Mould Using Non-Traditional Algorithms (pp. 9-14)

A.M. Dalavi, P.J. Pawar, T.P. Singh, A.S. Warke, P.D. Paliwal

Optimization of hole-making operations plays a crucial role in which tool travel and tool switch scheduling are the two major issues. Industrial products such as moulds, dies, engine block etc. consists of large number of holes having different diameters, depths and surface finish. This requiers large number of machining operations like drilling, reaming or tapping to achieve the final size of individual hole. This gives rise to large number of possible sequences to achieve final size of the hole. Optimal sequence of operations which reduces the overall processing cost of these hole-making operations are essential. Hence it is necessary to use non-traditional optimization techniques which are strong enough to handle these complex problems as well which gives optimal results. This paper reviews about the various non-traditional optimization techniques which are already implemented to solve optimization of hole-making operation problems.
