The Japanese production system has an ethnic or national basis. There are considered to be three production components of the system-shop-floor-centred work organization, waste-free production control, and participative management in the context of cooperative labour relations. For each of these, it is possible to set up a Japanese-type'. The author is conducting research into the overseas operations of Japanese subsidiaries in automobile assembly. Japanese multinational enterprises presumably try to apply the system to their overseas operations to take advantage of its strengths; however, given that they have moved into a foreign country, presumably Japanese enterprises have to adapt to the management environment of the local area. This research investigates the following questions: (i) Does this 'application' and 'adaptation' result in a dilemma? (ii) What is actually being applied and what has not been possible to apply? (iii) How well is the balance between 'application' and 'adaptation' being achieved? According to surveys of Japanese manufacturing plants in North America, Asia, and Europe, the application of the system is possible. Of course this does not mean that it can be applied 100%. The pattern of application varies according to the management strategy of the Japanese enterprises.

<p>The paper introduces a methodology to define production trend classes and also the results to serve with trend prognosis in a given manufacturing situation. The prognosis is valid for one, selected production measure (e.g. a quality dimension of one product, like diameters, angles, surface roughness, pressure, basis position, etc.) but the applied model takes into account the past values of many other, related production data collected typically on the shop-floor, too. Consequently, it is useful in batch or (customized) mass production environments. The proposed solution is applicable to realize production control inside the tolerance limits to proactively avoid the production process going outside from the given upper and lower tolerance limits.</p><p>The solution was developed and validated on real data collected on the shop-floor; the paper also summarizes the validated application results of the proposed methodology.</p>

The lean manufacturing concept is a systematic minimization of waste and non-value activities in production processes introduced by the Toyota production system. In this research, lean manufacturing is implemented in a cement production line. Value Stream Mapping (VSM) is applied to give a clear picture of the value chain in cement production processes and to highlight the non-value-added in the shop floor. To begin, the existing VSM is constructed based on the information and data gathered during visiting and observing the manufacturing process in the firm. As a result, the excess inventory between workstations was identified as a major waste generation, hence, the proposed VSM conducts further improvement and makes action plans to alleviate the unwanted activities. Then, the takt time to ensure smooth material flow and to avoid any occurring delay or bottleneck in the production line was figured out. The supermarket pull-based production control is suggested to be adopted in the future map. Two pull production strategies are selected in this case. The first is applying the Kanban system to control the level of inventory between workstations. The other is the CONWIP approach to control the amount of work in process to the entire production line. The outcome of the proposed models indicates a decrease of the none-value time from 23 days in the current state to about 4 and 2 days in Kanban and CONWIP systems respectively, so the CONWIP was suggested as most efficient. Some suggestions for further research are also mentioned.

Quando se reflete sobre as desvantagens da prática de enfermagem não sistematizada, pode-se perceber o quanto se está deixando de valorizar a própria profissão, colaborando para sua estagnação. Esta situação pode ser visualizada, quando da não realização de prescrição de enfermagem, passando a equipe de enfermagem a guiar suas ações fundamentalmente pela prescrição médica, tornando aparentemente desnecessária a participação do enfermeiro nas tomadas de decisão. A implantação da Sistematização da Assistência de Enfermagem (SAE) é uma necessidade à definição, diferenciação e valorização da profissão e dos profissionais da enfermagem, além de ser exigida legalmente pela Resolução COFEN 272/2002. Com este estudo tivemos como objetivos: a) identificar os motivos da não realização da Prescrição de Cuidados de Enfermagem nas Unidades de Internação de um Hospital Universitário; b) apontar possíveis alternativas para o aprimoramento das ações de enfermagem e estratégias favoráveis à implantação, implementação e consolidação da prescrição de cuidados de enfermagem. Os dados foram colhidos através de um questionário, respondido por 37 (trinta e sete) enfermeiros. Obtivemos como resultado: a falta de credibilidade e a cultura da desvalorização da prescrição de enfermagem; a exiguidade do tempo, a carência de pessoal e o não estabelecimento de prioridades na realização e organização do trabalho da enfermagem; percepções sobre suas repercussões na organização do trabalho, qualidade da assistência e valorização profissional e possíveis estratégias para sua realização.Nursing prescription: the reason why nursing care was not carried out and the problable implementing strategiesAbstractThis study objectified: a) identify the reasons why Nursing Care Prescription was not being carried out in the Admittance Units of a Teaching Hospital; b) point out feasible alternatives to foster favorable nursing actions and strategies to set up, implement and consolidate nursing care prescription. Data were gathered through a questionnaire answered by 37 (thirty-seven) nurses. The result was as follows: unreliability and culture for undervaluing nursing prescription; lack of time; staff shortage; non-outlined priorities in order to carry out and organize nursing tasks; perceptions on the repercussion of work organization, quality-level of practice and professional valuing, besides feasible strategies to carry it out.

Purpose Shop floor control systems are generally major points of discussion in production planning and control literature. The purpose of this paper is to investigate how lean production control principles can be used in a make-to-order (MTO) job shop, where the volume is typically low and there is high variety. This paper examines the procedures involved in implementing a constant work-in-process (CONWIP)/Kanban hybrid system in the shop floor environment and also provides insights and guidelines on the implementation of a hybrid system in a high-variety/low-volume environment. Design/methodology/approach The authors review literature on Kanban, CONWIP, and CONWIP/Kanban hybrid systems to analyze how lean production control principles can be used in a MTO job shop. The second part focuses on the process of implementation. Using a case study of a manufacturer of electromechanical components for valve monitoring and controls, the paper describes how the operation is transformed by for more efficient shop floor control systems. Real experiments are used to compare pre- and post-improvement performance. Findings The study shows that the proposed hybrid Kanban-CONWIP system reduced the cycle time and achieved an increase of 38 percent in inventory turnover. The empirical results from this pilot study provide useful managerial insights for a benchmarking analysis of the actions to be taken into consideration by companies that have similar manufacturing systems. Research limitations/implications The statistic generalization of the results is impossible due to the use of a single case method of study. Originality/value This paper provides insights and guidelines on the implementation of a hybrid system in a high-variety/low-volume environment. The literature on real applications of hybrid CONWIP/Kanban by case study is limited.

On-off of the standby system is an important factor that influences the performance of the production system. A dual threshold control strategy based on the on-off control of the standby system is proposed for the optimal control of the two-stage production system for which the last stage has stochastic production capacity. A control parameters optimization model is built with the objective of minimizing the total production cost, and a genetic algorithm is adopted to resolve the optimization problem. Finally, an example is taken to validate the effectiveness of the proposed dual threshold control strategy and the parameter optimization algorithm.
