摘要:We consider the problem of allocating demand arising from multiple products to multiple production facilities with finite capacity and load-dependent lead times. Production facilities can choose to manufacture items either to stock or to order. Products vary in their demand rates, holding and backordering costs, and service-level requirements. We develop models and solution procedures to determine the optimal allocation of demand to facilities and the optimal inventory level for products at ea...

摘要:Companies innovating in dynamic environments face the combined challenge of unforeseeable uncertainty (the inability to recognize the relevant influence variables and their functional relationships; thus, events and actions cannot be planned ahead of time) and high complexity (large number of variables and interactions; this leads to difficulty in assessing optimal actions beforehand). There are two fundamental strategies to manage innovation with unforeseeable uncertainty and complexity: tria...

摘要:We present a novel methodology for identifying public knowledge and eliminating the biases it creates when aggregating information in small group settings. A two-stage mechanism consisting of an information market and a coordination game is used to reveal and adjust for individuals' public information. A nonlinear aggregation of their decisions then allows for the calculation of the probability of the future outcome of an uncertain event, which can then be compared to both the objective probab...

摘要:This paper develops a new likelihood-based method for the simultaneous estimation of structural demand-and-supply models for markets with differentiated products. We specify an individual-level discrete-choice model of demand and derive the supply side assuming manufacturers compete in prices. The proposed estimation method considers price endogeneity through simultaneous estimation of demand and supply, allows for consumer heterogeneity; and incorporates a pricing rule consistent with economi...

摘要:This study asserted that quality improvement (QI) requires the coexistence of two cultural values of innovation and attention to detail and proposed that their coexistence depends on the implementation of multiple QI practices. A longitudinal QI intervention, with five phases, consisting of multiple QI practices-ISO 9000, QI teams, quality goals, and coaching and communication by top management-was implemented. Participants were 425 employees working in 18 departments of four manufacturing pla...

摘要:In this paper, we analyze the portfolio selection implications arising from imposing a value-at-risk (VaR) constraint on the mean-variance model, and compare them with those arising from the imposition of a conditional value-at-risk (CVaR) constraint. We show that for a given confidence level, a CVaR constraint is tighter than a VaR constraint if the CVaR and VaR bounds coincide. Consequently, a CVaR constraint is more effective than a VaR constraint as a tool to control slightly risk-averse a...

摘要:The paper Asymmetric Information, Incentives and Intrafirm Resource Allocation, by Harris, Kriebel, and Raviv, was published in the June 1982 issue of Management Science. In this article, written as part of this journal's 50-year anniversary celebration, we highlight the significance of the Harris et al. paper for research in managerial accounting. We first formulate and solve a continuous version of the Harris et al. model to illustrate the key assumptions and findings of their paper. We then...

摘要:This paper shows that business groups in emerging economies exert dual effects on innovation. While groups facilitate innovation by providing institutional infrastructure, groups also discourage innovation by creating entry barriers for nongroup firms and thereby inhibit the proliferation of new ideas. This pattern reflects an evolutionary process in which the interplay of the availability of innovation infrastructure and variety of ideas influences the level of innovation in an industry. We s...

摘要:Most of the traditional models in production and inventory control ignore the financial states of an organization and can lead to infeasible practices in real systems. This paper is the first attempt to incorporate asset-based financing into production decisions. Instead of setting a known, exogenously determined budgetary constraint as most existing models suggest, we model the available cash in each period as a function of assets and liabilities that may be updated periodically according to ...

摘要:The problem of designing, coordinating, and managing complex systems has been central to the management and organization literature. Recent writings have tended to offer modularity as at least a partial solution to this design problem. However, little attention has been paid to the problem of identifying what constitutes an appropriate modularization of a complex system. We develop a formal simulation model that allows us to carefully examine the dynamics of innovation and performance in compl...
