Today companies are implementing total productive maintenance in order to become world class industries to have a competitive edge over worldwide. In this regard Kobetsu Kaizen (Focused Improvement) pillar having a very significance effect to solve the specific problem. The main aim of this paper is to implement the complete Kobetsu Kaizen methodology of TPM, to solve the issue related with the sudden drop of availability rate of hobbing machine in a gear manufacturing cell. The result of the paper shows the advantage of Kobetsu Kaizen pillar implementation in the sense that breakdown frequency of the machine has been reduced considerably.

The need for manufacturing companies, particularly those in the defence sector, to become more competitive in global markets is well known. As a case study of what can be achieved, this paper describes a programme in which new approaches—including team working, world class manufacturing, production cells and JIT—were used to transform a traditional, protected manufacturing supply organization into a viable business to meet the challenge of low-cost international competition. The programme was called the ACE project.

Quantitative And Qualitative Methods

In the article two types of rent are differentiated: resource rent and administrative rent. The latter is linked to restrictions on the access to the field of interactions. The contribution of the theory of public choice and the theory of rent-seeking and directly-unproductive activities is further developed by shifting the emphasis from individual decision-making to interactions between three actors: C, who controls access to the field, A, who gets a competitive edge as a result, and B, who assumes a subjacent position with regard to both A and C, yet still receives a positive gain from transacting. Domination by virtue of a constellation of As, Bs, and Cs interests is illustrated with the help of an in-depth case study of a Russian region. This study combines quantitative and qualitative methods, as well as their triangulation.

Purpose: The purpose of this work is to present a method based on the application of method engineering, in order to eliminate downtime and improve the manufacturing cell.Design/methodology/approach: The research strategy employed was a case study applied to a manufacturing company to explore the causes of excessive dead time and low productivity. The methodology used was divided in five steps. The first corresponds to the analysis of the lathe and grinding process; the second is the elaboration of the man-machine diagram to identify dead times; the third is the application of the improvement proposal; the fourth is the redistribution of the cell to optimize the process; the fifth is to conclude from the results obtained.Findings: With the proposed method, the downtime was reduced by 41% and only 50% of the available labor is required, therefore, it is concluded that the method can be used to redesign manufacturing cells.Research limitations/implications: This research was limited to analyzing and improving human-machine interaction, since work is not just the machine, or the individual alone, or the individual manipulating the machine, therefore, no other tools were used to improve the time of machines operation.Practical implications: Designing a manufacturing cell that allows the operator to do his job with less fatigue and not adapt the operator to the job, as commonly happens.Social implications: Companies must show a greater interest in occupational health by including human capital in their optimization plans to avoid future harm to workers.Originality/value: The key contribution of this paper focused on developing a novel and practical methodology to design or re-design manufacturing cells to improve productivity considering the human factor, inspired by the main concepts of method engineering.

This paper looks at the City of Melbourne's new office development CH2 as a case study of world class energy performance. In particular, the integrated design of conventionally independent systems has led to the potential to deliver significant savings to the Council and to deliver better environmental conditions to building occupants that in turn may contribute to satisfaction, well-being and productivity. It is concluded that this project has the potential to be an iconic example of effective implementation of ESD (environmental sustainable design) principles and therefore act as a demonstration project to others. Energy efficiency of more than 50% of current benchmarks for Melbourne is effected. Energy harvesting is defined as arising from squander, waste and nature, which is a new concept introduced in this paper to better describe the design decision process.

This paper presents a multi-perspective approach to Modeling and Simulation (M&S) of Healthcare Systems (HS) such that different perspectives are defined and integrated together. The interactions between the isolated perspectives are done through dynamic update of models output-to-parameter integration during concurrent simulations. Most often, simulation-based studies of HS in the literature focus on specific problem like allocation of resources, disease propagation, and population dynamics that are studied with constant parameters from their respective experimental frames throughout the simulation. The proposed idea provides a closer representation of the real situation and helps to capture the interactions between seemingly independent concerns - and the effects of such interactions - in simulation results. The article provides a DEVS (Discrete Event System Specification)-based formalization of the loose integration of the different perspectives, an Object-Oriented framework for its realization and a case study as illustration and proof of concept.

From a macroeconomic standpoint, the Czech Republic has been viewed as a leading example of successful transformation from a state owned to a privatized economy. Yet at the firm and industry levels, the transformation process is still in its early stages. This article focuses on the transformation of outbound international business activities of the country and offers statistical and case study evidence to support four propositions describing the transformation process to date. First, most Czech international business activity is oriented toward its European neighbors. Second, globalization is beginning in a few selected firm and industries. Third, the reliance on low price rather than other international marketing advantages limits the development of world class images of Czech export commodities. Fourth, beginning globalization efforts of Czech firms focus on emerging markets of Asia, South America and Africa and to a lesser extent on the United States but largely exclude Japan.

Attempts to achieve optimization of machine and equipment maintenance at manufacturing companies over the years have encountered a multitude of problems. Due to equipment losses such as setup and adjustment, minor stops and delays, defective products due to equipment, reduced engine speed, and reduced output has influenced their desire to reach world class manufacturing levels. This paper discusses a large part of the TPM approach in manufacturing companies and provides an overview of the various TPM implementation practices demonstrated by manufacturing companies in the world.. Based on review results of the 50 journals about TPM in industries It was found that most of the TPM implementations used the OEE parameter to see the success rate of implementing this TPM. This paper also highlights the variable approach that is most widely used by various practitioners and researchers and evaluates in detail the success factors of implementing TPM and the reasons behind the failure of implementing TPM are also discussed so as to ensure the implementation of TPM can run smoothly and effectively in manufacturing companies
