摘要：Why do some new firms succeed and others fail? Economists argue that the new firms fail because entrepreneurs inefficiently manage production and organizational design (Williamson 1985). Sociologists (e.g., Granovetter 1985) have typically viewed this explanation as undersocialized, and argue that institutional legitimacy must also be considered to explain the survival of new firms. This paper examines the survival of 1292 new franchisors established in the United States from 1979-1996. The re...

摘要：Businesses around the world are paying more attention to process management and process automation to improve organizational efficiency and effectiveness. Ln this paper, we describe a general framework for implementing dynamic routing and operational control mechanisms in Workflow Management Systems (WMSs). The framework consists of three techniques: workflow control tables, sequence constraints, and event-based workflow management rules. Our approach offers several unique features that are mi...

摘要：The construction of a probabilistic model is a key step in most decision and risk analyses. Typically this is done by defining a joint distribution in terms of marginal and conditional distributions for the model's random variables. We describe an alternative approach that uses a copula to construct joint distributions and pairwise correlations to incorporate dependence among the variables. The approach is designed specifically to permit the use of an expert's subjective judgments of marginal ...

摘要：This paper investigates the effect upon performance in a service system, such as a telephone call center, of giving waiting customers state information. Ln particular, the paper studies two M/M/s/r queueing models with balking and reneging. For simplicity, it is assumed that each customer is willing to wait a fixed time before beginning service. However, customers differ, so the delay tolerances for successive customers are random. In particular, it is assumed that the delay tolerance of each ...
