摘要：How should organizations of intelligent agents be designed so that they exhibit high performance despite information distortion? We present a formal information-based network model of organizational performance given a distributed decision making environment in which agents encounter a radar detection task. Using this model, we examine rite performance of organizations with, various designs in different task environments subject to various types of information distortion, We distinguish five s...

摘要：We consider the situation of a supplier plant whose customer plants desire just-in-time (JIT) deliveries. Randomness in both the production and demand processes make satisfying every demand that might occur in true JIT fashion impossible. Therefore, supplier plants typically negotiate bounds on JIT contracts with their customers. In this paper, we focus on the use Of ''quotas'' or ''target inventory levels'' as a mechanism for establishing such bounds. That is, the supplier firm is responsible...

摘要：We consider Just-in-Time (JIT) to be an overall organizational phenomenon. Accordingly, we developed and tested a model that includes both JIT practices and the infrastructure practices hypothesized to provide an environment in which JIT practices perform more effectively. Canonical correlation analysis was used to test five hypotheses. The results indicated that: (1) there was not a significant relationship between the use of JIT practices, alone, and manufacturing performance; (2) there was ...

摘要：In this paper efficient bounds for the price of a call option are obtained using the decreasing absolute risk aversion (DARA) dominance rule. Such lower and upper bounds are obtained minimizing and maximizing, respectively, the objective function of a nonlinear optimization problem. An explicit formula (related to an exponential utility function) is given for the special case of three states of nature. A large number of experiments have been carried out and the numerical results support the co...

摘要：Information systems can serve as intermediaries between the buyers and the sellers in a market, creating an electronic marketplace that lowers the buyers' cost to acquire information about seller prices and product offerings. As a result, electronic marketplaces reduce the inefficiencies caused by buyer search costs, in the process reducing the ability of sellers to extract monopolistic profits while increasing the ability of markets to optimally allocate productive resources. This article mod...

摘要：This study explores the hypotheses that implementing effective total quality management (TQM) programs improves the operating performance of firms. The winning of quality awards is used as a proxy for the effective implementation of TQM programs. Changes in various performance measures for a test sample of quality-award winners are compared against a sample of control firms. Our statistical tests provide strong evidence that firms that have won quality awards outperform the control firms on op...

摘要：This paper provides exploratory evidence on the cross-sectional association between process management techniques and two profit measures: return on assets and return on sales. Using a sample of firms in two industries (automotive and computer) and four countries (Canada, Germany, Japan, and the United States), we find that certain process management techniques improve profitability while others have little effect on financial performance; In particular, long-term partnerships with suppliers a...

摘要：The dynamic nature of an operating environment, such as machine utilization and breakdown frequency results in changing preventive maintenance (PM) needs for manufacturing equipment. In this paper, we present an approach to generate an adaptive PM schedule which maximizes the net savings from PM subject to workforce constraints. The approach consists of two components: (a) task prioritization based on a multi-legit regression model for each type of PM task, and (b) task rescheduling based on a...

摘要：In this paper we investigate the relationship between the level of a firm's technological innovativeness and its pattern of partnership agreements (i.e., relative number of partnership agreements of one type versus another). We argue that the protection of tacit technological knowledge from potential opportunism is of importance to technologically innovative firms, and as a result they tend to have a relatively larger number of partnership agreements which generally minimize the transfer of ta...

摘要：In recent years it has been shown empirically that stock returns exhibit positive or negative autocorrelation, depending on observation frequency. In this context of autocorrelated returns the present paper is the first to derive an explicit analytical solution to the dynamic portfolio problem of an individual agent saving for retirement (or other change of status, like the purchase of a house or starting college). Using a normal ARMA(1, 1) process, dynamic programming techniques combined with...
