摘要:This paper considers two specific problems in telecommunication, namely the Terrestrial Flight Telephone System and the rerouting of international telephone calls. Both situations are modelled as coalitional games, and game theoretic techniques are used to tackle the problems. It is shown that a special class of coalitional games emerges from the situations under consideration and that the structure of the situations has theoretical implications, including the coincidence of several game theor...

摘要:We investigate the computational issues that need to be addressed when incorporating general cutting planes for mixed 0-1 programs into a branch-and-cut framework. The cuts we use are of the lift-and-project variety. Some of the issues addressed have a theoretical answer, but others are of an experimental nature and are settled by comparing alternatives on a set of test problems. The resulting code is a robust solver for mixed 0-1 programs. We compare it with several existing codes. On a wide ...

摘要:This paper investigates the psychometric properties of three measures of subjective uncertainty-a zero-to-hundred subjective probability scale and two seven point rating scales. Individual level analysis applied to data obtained from two separate studies suggests that the scales produce fairly similar results: The inter-response mode correlations were high, and individual plots comparing various methods were quite similar. Covariance structure models based on multitrait-multimethod matrices ar...

摘要:Empirical studies of information systems planning practices in organizations indicate that wide variations exist. We propose and test a model based on agency theory and transaction-costs economics to account for these variations. As senior management's uncertainty with respect to the information systems function increases, we argue they will delegate more decision rights to the information systems manager. As a result of increased agency costs, senior management will demand more information sy...

摘要:The paper establishes a positive security market line in the CAPM with nontraded endowments. The effects of a market structure change on the security market line are analyzed when the equilibrium allocation is affected by the change.

摘要:This work concerns the advance scheduling of elective surgery when the operating rooms' capacity utilization by emergency surgery, as well as by elective procedures, is uncertain. New requests for bookings of elective surgery arrive each day. Such procedures preferably would be performed as soon as possible, but admitting too many patients may result in exceeding a day's capacity, possibly necessitating turning away some emergency cases. So the problem facing the hospital at the start of each ...

摘要:Current research in organizational innovation is extensive, yet, because of limitations in scope, most studies are not adequately encompassing. These studies typically relate organizational variables to innovation and control at most for the effect of one contingency factor. Because innovation depends upon a complex host of factors, such theories have limited predictive application. This study intends to develop and test theories that explain the variation in the organizational complexity-inno...

摘要:Four antecedents, it is argued, are necessary precursors for a firm to capture rents from innovation. The antecedents are causal understanding; innovation team proficiency; emergence and mobilization of new competences; and creation of competitive advantages, each of which are conceptually distinct and precisely defined in the paper. These constructs are linked together in a stage model and subsequently operationalized and tested using LISREL. Substantial support is found for the central thesi...

摘要:This research addresses a system of flexible worker assignments in a setting where there are more workers than machines. When organized using this system, a production line balances itself by shifting the workloads continuously and automatically in response to changes in the state of the system. The system is, in effect, buffering itself against variation by altering the work assignments on the fly. This allows the system to operate with very low levels of work-in-process inventory (WIP). In t...

摘要:This research explores the performance consequences of CEO succession, executive team change, and strategic reorientation in different contexts. Based on team demography and organization learning ideas, we argue that CEO succession or executive team change enhances incremental organization change, while either strategic reorientation or the combination of CEO succession with executive team change triggers discontinuous organization change. We hypothesize that these contrasting intervention mod...
