Note on the ranking of fuzzy numbers: conditions for a total order relation
1988
It is well-known that the set of fuzzy numbers is not ordered. The author states the conditions which have to be satisfied so that the problem of ranking fuzzy numbers has a solution. In fact, the subset of fuzzy numbers, the elements of which are strictly defined and continuous,is endowed with a total order relation.
Treating Ordinal Criteria in Stochastic Weight Space Analysis
2001
We consider discrete co-operative group decision-making problems and suggest a method that is aimed at providing descriptive information about the acceptability of different decision alternatives. The method is a new variant of the Stochastic Multicriteria Acceptability Analysis (SMAA) method for discrete multicriteria decision-making problems with multiple decision makers. The new method is designed for problems where criterion information is completely or partially ordinal, that is, experts (or decision makers) have ranked the alternatives criterion-wise. The approach is particularly suitable for group decision making where either no or only partial preference information is available ass…
Multicriteria Decision Analysis for Choosing the Remediation Method for a Landfill Based on Mixed Ordinal and Cardinal Information
2009
We describe a real-life application of a multicriteria method in the context of remediating a landfill in Finland. The landfill was used for dumping industrial waste during the years 1950 to 1965. During that time many harmful chemicals were stored in landfills among other waste. Therefore, this—and possibly several other—landfills have to be remediated. In this application, seven different remediation options were evaluated based on 13 criteria. For some criteria, cardinal measures with associated uncertainties were obtained. For other criteria, only ordinal (ranking) information was available. The problem was analyzed using the Stochastic Multicriteria Acceptability Analysis with Ordinal …
Peer Discipline and Incentives Within Groups
2014
We investigate how a collusive group can sustain non-Nash actions by enforcing internal discipline through costly peer punishment. We give a simple and tractable characterization of schemes that minimize discipline costs while preserving incentive compatibility. We apply the model to a public goods contribution problem. We find that if the per-capita benefit from the public good is low, then regardless of whether peer discipline is feasible or not only small groups will contribute to the good. If the public good benefit is significant but peer discipline is infeasible it remains the case that only small groups contribute. On the other hand, if the public good benefit is significant but peer…
How individual characteristics shape the structure of social networks
2015
Abstract We study how students’ social networks emerge by documenting systematic patterns in the process of friendship formation of incoming students; these students all start out in a new environment and thus jointly create a new social network. As a specific novelty, we consider cooperativeness, time and risk preferences – elicited experimentally – together with factors like socioeconomic and personality characteristics. We find a number of robust predictors of link formation and of the position within the social network (local and global network centrality). In particular, cooperativeness has a complex association with link formation. We also find evidence for homophily along several dim…
Integrating human resource management into lean production and their impact on organizational performance
2011
PurposeThe first goal of this research is to analyse the effects of lean production (LP) on the policy of human resource management (HRM). The second is to determine whether or not implementation of HRM practices associated with LP explains the differences in organizational performance between manufacturing plants.Design/methodology/approachThe paper developed a questionnaire for data collection. Findings are presented from 76 establishments (79.17 per cent of the total sample) that specialise in single‐firing ceramic tiles in Spain.FindingsCompanies that make the most of LP practices are also those that take care to train workers in using these practices as well as improving their employme…
Corporate entrepreneurship and human resource management: theoretical background and a case study
2011
Purpose: This article aims to review varying concepts of entrepreneurship and different contributions to human resource practices, establishing a theoretical framework that allows for the analysis of the firm Montalt-Valencia (Spain), a Ford-Spain car dealer, and leader in its sector. Design/methodology/approach: The paper, according to the literature, establishes a theoretical framework on entrepreneurship and human resource management through which one can observe and research the Montalt-Valencia case study. The case study is confirmatory, from the theoretical background, and at the same time inductive from the observation of its non-expected details and deeds. Findings: The firm Montalt…
Time and strategy: towards a multitemporal view of the firm
2004
This paper takes into consideration the main views underlying the theory of the resource based firm within strategy studies, underscoring their fundamental monotemporal nature and proposing a way to elaborate a multi‐temporal view of the firm. By analyzing the link between the time concepts used as bases for the formulation of studies within the strategy field and the types of actor behavior implicitly (or explicitly) entailed by such time concepts, the paper shows the inadequacy of any one of the two monotemporal views of the resource‐based firm to encompass all of the main actor behaviors on which the firm's survival and success increasingly rests. The paper draws on the Austrian process …
The Role of External Environment in Upper Echelons Theory
2014
Upper echelons research has largely focused on the antecedents and consequences of top management teams (TMTs) from the team and firm levels of analysis. This paper reviews empirical research on TMTs with a specific emphasis on the role of the external environment. Applying institutional and industrial organization theories, a cross-level conceptual model outlining the direct, mediating, and moderating effects of the external environment on upper echelons is developed. This review distinguishes between industry and institutional levels of analysis and three types of environmental characteristics: stable, dynamic, and transformational. The paper further explains the relationships between ea…
Managing innovation of care services: An exploration of Norwegian municipalities
2016
AbstractThe social impact of care services provided by the public sector is significant. Nevertheless, these services have received relatively little attention from prior innovation management practices research. This paper addresses this gap by raising the question: What characterises management-driven innovation processes in public organisations providing care services? The qualitative exploration of this question is based on in-depth interviews with key managers in three Norwegian municipalities, and in-depth observation of one ongoing innovation initiative in one municipality. Our findings supplement the findings of prior research by showing that different actors are involved in differe…
