This volume presents most of the recent advances of the theory accomplished by scholars from around the world. From studying this book, the reader will not only acquire an overall knowledge of this new theory but also be able to follow the most current research activities. All examples presented are based on practical applications of the theory when urgent real-life problems had to be addressed.Last but not the least, this book concludes with three appendices. The first one compares grey systems theory and interval analysis while revealing the fact that interval analysis is a part of grey mathematics. The second appendix presents an array of different approaches of studying uncertainties. And, the last appendix shows how uncertainties appear using general systems approach.","brand":"WoB","offers":[{"title":"GB \/ NEW \/ INGRAM","offer_id":52138587128081,"sku":"NLS9783642423321","price":0.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0784\/4072\/6801\/files\/9783642423321.jpg?v=1757563777"},{"product_id":"grey-systems-analysis-book-sifeng-liu-9789811961625","title":"Grey Systems Analysis","description":"original difference grey model (ODGM), even difference grey model (EDGM), discrete grey model (DGM), fractional grey models, self-memory grey models;","brand":"WoB","offers":[{"title":"- \/ - \/ INTERNAL","offer_id":52402153980177,"sku":null,"price":0.0,"currency_code":"GBP","in_stock":true},{"title":"GB \/ NEW \/ INGRAM","offer_id":52402154733841,"sku":"NLS9789811961625","price":0.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0784\/4072\/6801\/files\/9789811961625.jpg?v=1758756908"},{"product_id":"grey-systems-book-sifeng-liu-9783642161575","title":"Grey Systems","description":"Due to inherent limitations in human sensing organs, most data collected for various purposes contain uncertainties.
