Cell formation (CF) problem is one of the most important decision problems in designing a cellular manufacturing system includes grouping machines into machine cells and parts into part families. Several factors should be considered in a cell formation problem. In this work, robust optimization of a mathematical model of a dynamic cell formation problem integrating CF, production planning and w...

هدف ما در این پایان نامه طراحی و ساخت سیستم مولد پلاسمای فلزات قلیایی به نام q-machine vertical می باشد.این سیستم از چند قسمت تقسیم شده است که عبارتند از: 1- محفظه خلا با اتصالات از نوع استاندارد cf و خلا اولیه بین6-10 تاtorr 8-10که بصورت استوانه ای و سه تکه و از جنس استنلس استیل 316 می باشد. 2- آهنرباهای الکتریکی: که وظیفه دارند میدان مغناطیسی محوری یکنواخت وثابتی در حدود 5/0 تسلا در طول قس...

This paper presents a new mathematical model for integrated dynamic cellular manufacturing systems and production planning that minimizes machine purchasing, intra-cell material handling, cell reconfiguration and setup costs. The presented model forms the manufacturing cells and determines the quantity of machine and movements  during each period of time. This problem is NP-hard, so a meta-heur...

purpose a metabolic abnormality such as obesity is a major obstacle in the maintenance of the human health system and causes various chronic diseases including type 2 diabetes, hypertension, cardiovascular diseases, as well as various cancers. this study was designed to summarize the recent scientific knowledge regarding the anti-obesity role of curcumin (diferuloylmethane), which is isolated f...

The present investigation presents a stochastic model for a flexible manufacturing system consisting of flexible machine, loading/unloading robot and an automated pallethandling device. We consider unreliable flexible manufacturing cell (FMC) wherein machine and robot operate under individual as well as common cause random failures. The pallethandling system is completely reliable. The pallet o...
