Fuzzy Linear Programming in Practice: An Application to the Spanish Football League
2010
FLP problems are perhaps one of the most and best studied topics of Soft Computing, and are among the most fruitful in applications and in theoretical and practical results. Areas of application of FLP problems are many and varied and in fact suppose an extraordinary example of technology transfer in action. In this paper, Fuzzy Linear Programming models are applied to the European football game in which the inherent uncertainty of the parameters relating to the football teams in the Spanish Football League serve to establish these models and so optimize the returns of the investments made to maintain a high quality competition. In this context, fuzzy DEA models are established which provid…
Old or new occupants of energy rehabilitated buildings. Two different approaches for hierarchizing group of buildings
2017
Abstract Public Administrations are frequently entitled to intervene in building stocks with energy rehabilitation actions. Unfortunately, the monetary budget at their disposal is generally limited and, consequently, a prioritization criterion is needed to optimize its allocation. The classification of the building energy performance is increasingly used by Public Administrations for this purpose. Here we argue that a proper prioritization criterion should depend upon the potential subjects to which the rehabilitated buildings are given back. If the energy rehabilitation is conducted on buildings that will be assigned to new dwellers, it would be preferable to use the energy class – which i…
Pianificazione strategica tra sviluppo locale e policentrismo: alcune evidenze empiriche sul caso siciliano
2009
Strategic planning, local development and policentrism: empirical evidence for Sicily The aim of this paper is the analysis of metropolitan strategic planning in Sicily. Urban areas are becoming important units for territorial cohesion policy and strategic planning represents more and more an important policy instrument. Evidence of a policentric pattern is tested across 30 strategic plans carried out by Sicilian cities in order to derive useful insights for policy implications. Methods and Results This study uses multidimensional scaling and rank-size regressions across Sicilian Functional Urban Areas (FUA) as well as descriptive information drawn from strategic plans in order to identify …
The strategy formation process in the EFQM Excellence Model: a critical review and new perspectives
2011
The adoption of an integrative strategy formation process becomes a way of developing a strategic capability that contributes to generating positive results and sustainable competitive advantages. In today's environments, many companies are also using the EFQM Excellence Model (EEM) to try to develop such a strategic capability. This paper presents an exhaustive review of the literature on the strategic process debate and on the strategic capability of the EEM. As a result, we offer to practitioners a conceptual framework which shows the EEM as a useful driver to facilitate the development of an integrative strategy formation process, and we propose a set of dimensions and variables (the le…
High commitment HR practices, the employment relationship and job performance: A test of a mediation model
2016
Abstract Purpose This study outlines and tests a high commitment model of human resource (HR) practices and its association with outcomes through a path including employee perceptions and attitudes, thereby seeking a new way of opening the so-called ‘black box’ between human resource management (HRM) and performance. Methodology Data were collected through a questionnaire survey with responses from 835 Spanish workers from three sectors (services, education and food manufacture). In order to test hypotheses, we conducted a path analysis. Findings High commitment HR practices were related to employee performance through the mediating effect of perceived organizational support, a fulfilled ps…
Explaining the relationship between socially responsible products and the operations of the firm: The case of equine assisted therapy
2018
Abstract Although there is a growing interest in social responsibility in research as well as in practice, the majority of studies on corporate social responsibility do not explicitly investigate operations management issues when adopting socially responsible practices under the “people” pillar of sustainability. This paper, dealing with the theme of social responsibility in operations management, aims at clarifying the complex relationship between socially responsible product/service and the operations of the company. The empirical context of the study is the sport industry, where the attention to social issues is well established. We used a mixed theoretical-empirical approach to develop …
Firefly algorithm based upon slicing structure encoding for unequal facility layout problem
2019
Finding the locations of departments or machines in a workspace is classified as a Facility Layout Problem. Good placement of departments has a relevant influence on manufacturing costs, work in process, lead times and production efficiency. This paper analyses the problem of allocating departments with restrictions in terms of unequal area and rectangular shape within a facility, in order to minimize the sum of material handling costs taking into account the satisfaction of the aspect ratio requested. In particular, we propose for the first time a Firefly Algorithm based on the slicing structure encoding. The proposed method was tested comparing the results obtained from other authors on t…
Closed-loop supply chains: What reverse logistics factors influence performance?
2016
This paper analyses the inventory and order flow dynamics in closed-loop supply chains (CLSCs). In this kind of supply chains the reverse flow of materials entering the system for recycling purposes complicates the way in which inventories should be managed and replenishment policies should be designed. Specifically, we analyse the relationships between some reverse logistics’ factors (remanufacturing lead-time, return rate of recycled products, reverse order policy, and number of supply chain tiers) on the order and inventory variance amplification. We firstly perform a systematic literature review of the related studies. Secondly, by adopting a difference equation math approach and design…
Impact of reverse logistics on supply chain performance
2013
Purpose – The purpose of this paper is to analyse the impact of reverse logistics on order and inventory variance amplification in a single-echelon supply chain (SC) and to propose a new order policy for dampening such amplification. Design/methodology/approach – A general review of the literature on sustainable operations and on the impact of reverse logistics on SC performance provides the foundation for the study. The authors use difference equation math approach for modelling and analysing a closed SC. A proper design of experiment and data collected from the European Union statistics validate the obtained numerical results. Findings – The variability of reverse flow in a closed loop S…
Do horizontal relationships matter to production and operations managers?
2014
This paper shifts the focus of production, operations and supply chain management business relationships from the vertical to the horizontal side and calls for more research on this issue. The main intent is to provide managerially oriented arguments regarding the linkages between the achievement of operations-related goals and decisions related to horizontal business relationships. Specifically, we address the following research question: Does a linkage exist between production and operations objectives and the decisions a company makes about horizontal agreements, particularly horizontal governance mode choice? To answer this research question, we develop literature-based hypotheses and c…
