This book is designed to offer a lively applied presentation of analytical and empirical tool for Bicriteria in flow-shop scheduling problems. It employs several pedagogical devices to help the readers to learn the new concepts quickly and absorb them fully. Classical flow shop scheduling problems mainly concerned with completion time related objects. in modern manufacturing and operation managements, the minimization of utilization time/rental cost of the machines with minimum make-span are the significant factors for the reason of upward stress of completion on the market. The Bicriteria...

La recherche en orthodontie a suivi le modèle positiviste de relation directe de cause à effet entre les maladies et leurs facteurs étiologiques qui provoquent des changements structurels et physiologiques dans le corps humain.1 Malgré l'objectivité et le bon potentiel des procédures statistiques, les méthodes quantitatives partagent progressivement l'espace avec d'autres modèles, principalement en raison de l'incapacité des premières à surmonter les multiples facteurs qui affectent le processus santé-maladie, qui jusqu'alors était réduit à sa dimension biologique. 2La...

Die Forschung in der Kieferorthopädie folgte dem positivistischen Modell der direkten Beziehung von Ursache und Wirkung zwischen Krankheiten und ihren ätiologischen Faktoren, die strukturelle und physiologische Veränderungen im menschlichen Körper verursachen. 1 Trotz der Objektivität und des guten Potenzials der statistischen Verfahren teilen sich die quantitativen Methoden nach und nach den Raum mit anderen Modellen, was vor allem darauf zurückzuführen ist, dass die ersteren nicht in der Lage sind, die vielfältigen Faktoren zu überwinden, die den Gesundheits- und Krankheitsprozess...

Research in orthodontics has followed the positivist model of direct relationship of cause and effect between diseases and its etiological factors which cause structural and physiological changes within the human body.1. Despite the objectivity and good potential of statistical procedures, quantitative methods are progressively sharing space with other models, mainly due to the former's inability to overcome the multiple factors that affect the health-disease process, which until that time was reduced to its biological dimension. 2. The recognition of the multifactorial nature of malocclusion...

This book is an attempt to analyze the bi-serial queue network models with Priority discipline. The proposed Queuing Models have been analyzed in Stochastic Environment. The Chapman- Kolmogorov equations (CKE) are used to define the joint probability distributions with associated probabilities and satisfied all required conditions for the existence of time - independent solutions in stochastic process. The present study is useful to reduce congestions and idle period of service systems. The applicability of the study finds in banking sectors, medical, registrations and administrations and...

This book is an attempt to analysis of feedback queue models with heterogeneous and homogeneous servers.The proposed queue models have been analysed in fuzzy environment. Two different approaches which are alpha-cut and L-R method for triangular fuzzy numbers have been used to evaluate queue performance measures. A comparison between utilization factors using both the approaches has been done at the end of each chapter. The proposed work in this book is very much applicable to daily life situations like as, in super markets, shopping malls, industries etc.
