The manufacturer's requirement of increasing productivity results in the need to design work stations that are increasingly more effective and specialized. However, this procedure can bring about an overloading of the worker, a lack of motivation, and, consequently, a reduction in productivity.Ergonomics adapts the work station to the worker with the object of improving his welfare and satisfaction at his post. One aspect that this science concerns itself with is the evaluation of physical demands connected to productive tasks. Mechanical movements are also studied in order to perform tasks efficiently.We here propose a new method of physical demand analysis that determines the risk factor for muscular skeletal lesion. This method uses, as a base, the system of predetermined times, MTM-UAS. It includes a computer system that allows us to easily analyse the operations at a work station and generates charts similar to those of UAS, but, instead of times, it measures the quantity of mechanical work necessary for each movement.The information that the method provides can be used by different divisions within companies in making decisions about improvements at work stations.  相似文献

We describe a common pool resource game in which players choose how much of the stock to extract in a sequential manner. There are two choices and one represents taking a larger proportion of the stock than the other. After a player makes a choice, the remaining stock grows at a constant rate. We consider a game with a finite number of alternating moves. It is shown that changes in the larger proportion of the stock that the players are allowed to take and the growth rate affect equilibrium, but have little effect on behavior in the laboratory. In addition to observing more cooperation than predicted, we observe that parameters that are strategically irrelevant affect behavior. The results of this research might help policy makers in developing adequate policies to prevent overexploitation of some natural renewable resources.  相似文献

We report results of one-shot traveler’s dilemma game experiments to test the predictions of a model of introspection. The model describes a noisy out-of-equilibrium process by which players reach a decision of what to do in one-shot games. To test the robustness of the model and to compare it to other models of introspection without noise, we introduce non-binding advice. Advice has the effect of coordinating all players’ beliefs onto a common strategy. Experimentally, advice is implemented by asking subjects who participated in a repeated traveler’s dilemma game to recommend an action to subjects playing one-shot games with identical parameters. In contrast to observations, models based on best-response dynamics would predict lower claims than the advised. We show that our model’s predictions with and without advice are consistent with the data.   相似文献

Are the atmospheric variables equally relevant for supermarket and hypermarket customers? As a contribution to the customers' choice of the store format, firstly this work aims to determine the perception of differences between hypermarkets and supermarkets in terms of store attributes. Second, it sheds light on the role played by atmospherics in the customers' decision process. This study uses a logit approach to model the probabilistic choice of the customers' store format using atmospheric and other marketing variables as important attributes of the grocery store. The model's estimation is based on personal interviews conducted during the shopping process in urban supermarkets and hypermarkets belonging to the same retail chain. The findings show that although the atmospheric variables are significantly important for both store formats, the customers perceive differently the importance of each retail atmospheric cue and other marketing variables, when buying in a hypermarket or in a supermarket: the choice of buying in hypermarket is explained by the significant importance given to the latent variables named pleasant atmosphere and accessibility and responsiveness; in contrast, the choice of buying in supermarkets is explained by the significant importance given to the latent variable nice decoration and empathy with the staff. The other latent variable designated by other marketing variables is only significantly important in the decision of choosing supermarkets.  相似文献

The study of stochastic comparisons of coherent systems with different structures is a relevant topic in reliability theory. Several results have been obtained for specific distributions. The present paper is focused on distribution-free comparisons, that is, orderings which do not depend on the component distributions. Different assumptions for the component lifetimes are considered which lead us to different comparison techniques. Thus, if the components are independent and identically distributed (IID) or exchangeable, the orderings are obtained by using signatures. If they are just ID (homogeneous components), then ordering results for distorted distributions are used. In the general case or in the case of independent (heterogeneous) components, a similar technique based on generalized distorted distributions is applied. In these cases, the ordering results may depend on the copula used to model the dependence between the component lifetimes. Some illustrative examples are included in each case.  相似文献

The long history and deep-rooted tradition of co-operative credit in Spain (credit co-operatives and credit sections of co-operatives) and the lack of detailed studies of the latter suggest the need to reflect on them and highlight their potential. This study examines the ways in which the credit sections can access the financial markets, describes their financial and economic structure and the sources of their income and expenditure and analyses their competitiveness in terms of efficiency.  相似文献

The aim of this exploratory paper is to fill an important gap in the international marketing literature by examining the influence of firm behavior in foreign markets (export commitment and adaptation of marketing tactics) on perceived competitive advantages and export performance. Using a sample of 150 Spanish export firms, the study found that firms that are more committed to their foreign markets are more willing to adapt elements of the marketing program. These firms also perform better in foreign markets. Moreover, the results also point out that adapting marketing tactics does not have direct effects on export performance, although it does have on the achievement of perceived competitive advantages in foreign markets, which positively influence export performance.  相似文献

This paper analyses the evolution of the welfare states in themajority of OECD countries during the pre-globalisation (1946–80)and globalisation (1980–2000) periods. Our purpose isto find out whether globalisation has produced a convergencetowards a smaller welfare state, funded increasingly by non-mobilefactors such as labour, property and consumption rather thanby mobile factors such as capital. The data presented here challengethe claims about such a convergence, showing that social publicexpenditures and public employment have continued to expandduring the globalisation period in most OECD countries. We alsoshow that the welfare states remain rooted in the politicaltraditions that have governed them.  相似文献

In this paper, we examine some popular 'choice modelling' approaches to environmental valuation, which can be considered as alternatives to more familiar valuation techniques based on stated preferences such as the contingent valuation method. A number of choice modelling methods are consistent with consumer theory, and its focus on an attribute‐based theory of value permits a superior representation of many environmental management contexts. However, choice modelling surveys can place a severe cognitive burden upon respondents and induce satisficing rather than maximising behavioural patterns. In this framework, we seek to identify the best available choice modelling alternative and investigate its potential to 'solve' some of the major biases associated with standard contingent valuation. We then discuss its use in the light of policy appraisal needs within the EU. An application to the demand for rock climbing in Scotland is provided as an illustration.  相似文献

This study examines how service supplier and buyer value co-creation influences buyers' attitudes toward service providers. Service-dominant logic is a prevalent concept in the services industry, providing an important marketing theory in which intangible resources, co-creation of value, and relationships are the keys to determining marketing exchanges. This research describes a model for analyzing value co-creation management in the hotel industry, focusing on the specific market segment of disabled customers. This framework helps foster value co-creation to increase the benefits for participants during each stage of their relationship. The paper also presents the managerial implications of the research findings.  相似文献
