摘要:In this paper we investigate some of the organizational factors that influence subsidiary-headquarters and intersubsidiary communication in multinational companies. Our study is based on data collected from 164 senior managers working in 14 different national subsidiaries within the consumer electronics division of Matsushita, a Japanese company, and 84 senior managers working in nine different national subsidiaries within the same business of N.V. Philips, the Holland-based competitor of Mats...

摘要:The stochastic properties of discretely rebalanced option hedges have been studied extensively beginning with Black and Scholes (1973). In each analysis hedges were ''delta-neutral'' after rebalancing. We argue that the distributional properties of discretely rebalanced hedges are such that delta-based hedging is not the variance minimizing strategy. This paper obtains analytical expressions for the variance minimizing option hedge ratios. We also evaluate the hedge variance to assess the magn...

摘要:Novel workweek arrangements have gained acceptance in many seven-days-a-week operations, such as hospitals and data processing centers. This note considers a multiple-shift workforce scheduling scenario for seven-days-a-week operations under a workweek arrangement called the 3-4 workweek. Our model seeks to minimize the workforce size subject to satisfying staffing requirements and workrules relating to off-days, off-weekends, and work-stretches. We provide an efficient optimal algorithm which...

摘要:Culture is defined in terms of components and parts. The logical nature of the components and of the connections between them are identified and analyzed. These connections are used as a basis for the argument that there is a meaningful concept of the fit between the components of the organization structure and those of its cultural setting. This concept of fit is defined and the values it may logically take are identified. A theory on the goodness and badness of fit between structure componen...

摘要:We bound the difference in performance measures among different orders of tandem queues when service times are nonoverlapping. Two types of nonoverlapping service times, with respect to (w.r.t.) tasks and w.r.t. customers, are defined; it is not required that service times be independent. For nonoverlapping service times w.r.t. tasks, we bound the sample-path difference in number of customers in system by one, and bound the corresponding time-average difference by the traffic intensity of the ...

摘要:Kanban-controlled serial manufacturing systems have been popular in Japan for many years. The analytical intractibility of such systems makes simulation and heuristics essential in studying them. In this paper we develop some theoretical results-reversibility and dominance-that characterize the dynamics of these systems, provide insight into their behavior and help greatly reduce the simulation effort needed to study them. These structural results also provide the basis for developing heuristi...

摘要:The evidence is clear that a lack of attention to structured tool management has resulted in the poor performance of many manufacturing systems. Plant tooling systems affect product design options, machine loading, job batching, capacity scheduling, and real-time part routing decisions. With increasing automation in manufacturing systems, there is a growing need to integrate tool management more thoroughly into system design, planning and control. This paper critically evaluates various tool m...

摘要:Hypertension is one of the most important risk factors with respect to coronary heart disease and stroke. The benefits of early detection of hypertension and the subsequent design of follow-up treatment programs are well documented. Consequently, screening programs have been designed to identify subjects as normotensive (normal) or hypertensive (abnormal). In order for these programs to be effective, full participation of the subject population is required. However, such classification program...

摘要:High-Definition Television promises to be the next generation of television. This technology has broad implications for consumer markets, as well as the underlying manufacturing, technology development, and R&D activities of firms. Under increasing pressure from various groups, the U.S. government must make major policy and funding decisions based on its assessment of the likely demand for HDTV. Three published reports which forecast sales of HDTV after its scheduled introduction in the mid-19...

摘要:One important implementation of Bayesian forecasting is the Multi-State Kalman Filter (MSKF) method. It is particularly suited for short and irregular time series data. In certain applications, time series data are available on numerous parallel observational units which, while not having cause-and-effect relationships between them, are subject to the same external forces (e.g., business cycles). Treating them separately may lose useful information for forecasting. For such situations, involvi...
