Production planning in reconfigurable enterprises and reconfigurable production systems

2005

Reconfigurable enterprises and reconfigurable production systems represent nowadays one of the key responses towards the organisational and manufacturing needs arising in the new era known as mass customization. The paper proposes an Agent Based approach for the production planning activities in reconfigurable enterprises, characterized by complex, articulated and geographically distributed production capacities contended by many product families and composed by reconfigurable production systems that allow quick adjustment of production capacity and functionality consenting to manufacture different products of the same part family.

High Level Planning of Reconfigurable Enterprises: a Game Theoretic Approach

2006

Reconfigurable Enterprises (REs) represent production networks made of different and geographically dispersed plants that, in case of unpredictable market changes, can be reconfigured in order to gather a specific production objective. However, REs effectiveness and efficiency depend on the extent to which global performance is obtained. Basically two approaches are available to reach coordination: centralised or decentralised planning tools. In this paper, the authors propose a novel cooperative game theoretical approach for distributed production planning at high level of a RE; the proposed approach has been benchmarked in front of both a distributed one, based on negotiation, and a centr…

Diseased Social Predators

2017

Social predators benefit from cooperation in the form of increased hunting success, but may be at higher risk of disease infection due to living in groups. Here, we use mathematical modeling to investigate the impact of disease transmission on the population dynamics benefits provided by group hunting. We consider a predator-prey model with foraging facilitation that can induce strong Allee effects in the predators. We extend this model by an infectious disease spreading horizontally and vertically in the predator population. The model is a system of three nonlinear differential equations. We analyze the equilibrium points and their stability as well as one- and two-parameter bifurcations. …

Genome-wide association study for milk production traits in an economically important local dairy sheep breed

2021

In this study, we conducted a genome-wide association study (GWAS) for five milk production traits in the Valle del Belice sheep. Repeated measurements for milk yield (MY), fat percentage and yield (F% and FY) and protein percentage and yield (P% and PY) on 481 ewes, were available for the analysis. The animals were genotyped using the Illumina Ovine 50k BeadChip. Weighted deregressed breeding values (DEBVw) were used as phenotypes for GWAS analysis. A total of 23 genome-wide significant SNPs were identified: 3 associated with MY, 9 with FY, and 11 with P%. Several SNPs mapped within known candidate genes or previously reported QTL for milk production traits in livestock species. Additional…

Technique of Statistical Validation of Rival Models for Fatigue Crack Growth Process and Its Identification

2011

The development of suitable models of stochastic crack growth process is important for the reliability analysis of fatigued structures as well as the scheduling of inspection and repair/replacement maintenance. Based on modifications of the solution of the deterministic differential equation for the crack growth rate, where a stochastic nature of this rate is expressed by a random disturbance embedded in the solution of the differential equation, the simple stochastic models are presented for practical applications. Each of these models represents a stochastic version of the solution of the Paris-Erdogan law equation. The models take into account the random disturbance parameters while main…

Management of Infertility: A Practical Approach

2022

Management of Infertility: A Practical Approach offers an accurate and complete reference for the management of infertility and a robust step-by-step guide for assisted reproduction technologies (ARTs), including how to plan, design and organize a clinical setting and laboratory. The book also provides an evidence-based, complete and practical description of the available methods for diagnosis and management of male and female infertility. This will be an ideal resource for researchers, students and clinicians who want to gain complete knowledge about both basic and advanced information surrounding the diagnosis and management of infertility and related disorders.

A FAST Method to Achieve Flexible Production Programming Systems

2008

One of the main critical problems in manufacturing system domains is the production scheduling process, because an agile and reactive production planning and scheduling system is essential in manufacturing. The production scheduling process is a complex problem in which finding a suitable production scheduling can greatly increase the effectiveness of highly flexible production processes. Nevertheless, this high flexibility makes the production scheduling and acquisition of relevant data quite complicated. Therefore, there is a strong demand for a universal and flexible tool for production scheduling capable of increasing the utilization of resources and that supports a decision-making proc…

Análisis de la producción y el consumo de información en los artículos españoles sobre bibliometría

1996

We analyze Spanish production of papers on bibliometrics published in Spanish scientific journals and the use of information through the method of bibliographic reference analysis. Publications have been obtained from IME, ICYT and ISOC databases. The number of papers was 101 , with 1848 citations. The most important citations are to journal articles and Spanish publications, but <i>Scientometrics</i> is the most cited journal. Results seem to show that bibliometrics is a young discipline in our country, with an important role of classic authors. Difficulties of access to foreign bibliography produce a high use of Spanish publications. Medicine and Psychology are the most influe…
