This book unfolds into a collection of three distinct strategic management articles that share an interest in supply firms, or “peripheral firms”. The three studies offer a novel theoretical perspective named the "peripheral view of manufacturing networks". Building on the relational view research this new perspective identifies the supplier-based theoretical standpoint to analyze and explain the antecedents of relational rents in manufacturing networks. This work is aimed at contributing both to strategy and operations management scholars, and more in general to practitioners who deal with supply chain management in technology-based industries.
Closed Queuing Networks are used in modeling systems such as Flexible Manufacturing (FMS), CONWIP Material Control, Computer/Communication Systems, Biotech Manufacturing and Health Care. Mean Value Analysis (MVA) is often used to compute the performance measures for these models. For networks with multiple-server stations, the exact MVA algorithm becomes computationally complex. The Schweitzer-Bard (S-B) approximation for MVA is simple and computationally efficient. However it has only been developed for networks with single-server stations. We provide a simple extension to S-B MVA to enable the analysis of networks with multiple-server stations. We develop an approximation for networks with single customer classes and then extend it to networks with multiple customer classes and general service time distributions. Comparison with exact results and simulation experiments for a wide variety of network configurations demonstrates the accuracy of this approach.
Sustainable development decision making should consider the possible impact on three roots of sustainability: environment, society and economy. One always must keep in mind that what the impacts of him/her decision are toward future generations. Mangers of any manufacturing company are now aware of the importance of manufacturing their products using a sustainable approach so that they can move toward sustainable manufacturing. One important step to achieve this goal is to control the impact of their manufactured products toward three dimensions of sustainability. A twofold case study was conducted on an automotive product integrated with a fuzzy evaluation method based on LCA principals: (1) sustainability assessment of current design and identifying the weak points; (2) improving the identified weak point and reassessment of its sustainability index. A Graphical User Interface was developed based on MATLAB coding in order to facilitate the product sustainability assessment. Outcomes of this case study show that how a simple improvement in material selection can contribute toward sustainable product development.
Today we are living in a information technological age where computer networks are playing a big role. On the other hand due to globalization and complex competitive market situation the world’s people are going with speed. The role of scheduling theory is increasing day by day in minimize the idle time of man and machine at work. The waiting time problem can be solve by using scheduling technique to meet the objective of the organization with efficiency and effectiveness. Manufacturing industries are the backbone in the economic structure of a nation. As the benefits from a manufacturing system can be maximized if the available resources are utilized in an optimize manner. Optimized utilization of resources can only be possible if there is a proper scheduling system in place. This makes scheduling a highly important aspect of a manufacturing system.
Recently, the world has experienced a massive a transformation into being a global digital village, and In this view, the online social networks have emerged as a big player in this transformation. There is a great educational potentials in social networks if effectively used for that purpose, and the communities especially in developing world have not utilized fully except for socialization. Henceforth, this book is all about the integration of the social networks such as Facebook,Blogs, Twitter and others into education.
Green communications is a very hot topic. As mobile networks evolve in terms of higher rates/throughput, a consequent impact on operating costs is due to (aggregate) network energy consumption. As such, design on 4G networks and beyond have increasingly started to focus on `energy efficiency' or so-called ‘green' networks. Many techniques and solutions have been proposed to enhance the energy efficiency of mobile networks, yet no book has provided an in-depth analysis of the energy consumption issues in mobile networks nor has detailed theories, tools and solutions for solving the energy efficiency problems. This book presents the techniques and solutions for enhancing energy efficiency of future mobile networks, and consists of three major parts. The first part presents a general description of mobile network evolution in terms of both capacity and energy efficiency. The second part discusses the advanced techniques to green mobile networks. The third part discusses the solutions that enhance mobile network energy efficiency as well as provides future directions. Whilst the reader is expected to have basic knowledge of wireless communications, the authors present a brief introduction of the evolution of mobile networks, providing the knowledge base for understanding the content of the book. In addition, complicated network problems are illustrated using simple examples. This will help the reader understand the concept and intuition of various techniques and solutions. Incorporates the latest research results from both academia and industry, providing an up-to-date overview of existing technologies and solutions on making mobile networks greener Consists of three sections with a gradually increasing technical depth on green mobile networks, providing the reader with a systematic view of the research area, and helping those with different technical backgrounds to better understand the content Covers existing enabling technologies for green mobile networking, including an innovative discussion of state-of-the-art solutions and algorithms
The View from Here is a study of our must fundamental attitudes toward the past. The book explores the dynamics of affirmation and regret, tracing the connections of each to our ongoing attachments. The focus is on situations in which our attachments commit us to affirming events or decisions that we know to have been unfortunate or regrettable.
The book presents a simple algorithm for mobile ad-hoc networks. this algorithm can be used further for analysis and simulation purpose. Mobile ad-hoc networks uses nodes on a fly and is gaining importance now-a-days. various routing and performance analysis approaches have been introduced till date. this is a interesting research area for both under-graduate and post-graduate students. from this book students get a view of how these networks behaves in practice.
