In recent years, the companies concerned with Flexible Manufbcming Systems(FMS), because of requirements about low volume production, short product life, availability of the new products for the market in a short time and flexibility of design and production management. A Flexible Manufactwing System is a set of computer-numerically controlled machine tools connected by an automatic material handling system and all controlled by a central computer system.In this study, a goal programming model is developed for flexible manufacturing systems that consist of several machine and work parts and has automatic material handling system. Every work part has different routes for which alternative machines can be used for part production This model is tested for problems with different sizes.Multiple-criteria programming approach is used to consider the distance factor between machines in loading and routing problems in FMS.
ÖzetBir işletmenin en temel amacı, meydana getirdiği bir ürün veya hizmeti tüketicisine ulaştırıp çalıştığı, hizmet verdiği alanda gelir sağlamaktır. İşletmelerin varlıklarını devam ettirebilmeleri ve rekabet üstünlüğü sağlayabilmeleri için, ellerindeki kaynakları yüksek verimlilikle, yüksek kalitede ve düşük maliyetle sağlamaları gerekmektedir. Bir işletmede depolama faaliyetleri toplam işletme maliyetleri içinde önemli bir paya sahiptir. Sipariş toplama ise, depolama faaliyetleri arasında en maliyetli ve en çok işgücü gerektiren işlemlerden bir tanesidir. Sipariş toplama, müşteri siparişlerinin çizelgelenmesi ve kümelenmesi, siparişlerin zemine bırakılması, stok alanlarından parçaların toplanması ve siparişlerin elden çıkarılması proseslerini içermektedir. Yapılan çalışmada, sipariş toplama politikaları ve otomatik depolama ve boşaltma sistemleri üzerine literatür araştırması yapılmıştır. Sipariş toplama politikaları ve otomatik depolama sistemleri üzerine yapılan çalışmalar incelenerek, çalışmalarda kullanılan yaklaşımlar ve literatüre katkıları üzerinde durulmuştur.Anahtar Kelimeler: Depolama maliyetleri, otomatik depolama ve boşaltma sistemleri, sipariş toplama politikaları
Literature Survey: Order Picking Policy and Automated Storage and Retrieval
Systems (AS/RS) AbstractMain purpose of an enterprise is to obtain gain in its business the area in which it products materials or it presents service to customers. In order to carry on their presence and to supply rival business advantage, enterprises have to use resources efficiently in case of high quality and low costs. Storage facilities costs encloses an important percantage of total enterprise costs. Order picking is one of the most labour intensive and cost effective operation of storage operations. Order picking process contains operations like scheduling of customer orders, grouping of orders, picking orders from storage locations, carrying orders to I/O points. In this paper a literature review on order picking policies and AS/RS systems is given. In this paper gains of the previous studies in literature and the approaches that are used in previous studies in literature is presented by analysing previous studies on order picking policies and AS/RS systems.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
