CEBİRSEL BİR YAKLAŞIM KULLANILARAK DÜŞÜK KALİTE, TARAMA, YENİDEN İŞLEME/TAMİR ETME İLE ÜRETİM PARTİ HACMİNİN ELDE EDİLMESİ

Abstract

Birçok araştırmacı, optimal sipariş miktarı veya optimal üretim miktarının kapalı formda matematiksel eşitliklerini elde etmek için birinci ve ikinci dereceden kısmi türevlere izin veren geleneksel hesaplama yöntemlerini kullanmaktadır. Ancak, bu çalışma, ürün tarama işleminin üretim sırasında ve üretim sonunda yürütüldüğü ve üretilen kusurlu ürünlerin indirimli fiyatla satıldığı ya da belirli bir maliyetle yeniden işlendiği/tamir edildiği bir kusurlu üretim envanter sisteminde, üretim parti hacmi belirleme probleminin çözümlerine cebirsel bir yaklaşım sunmaktadır. Diferansiyel hesabı bilmeyen uygulamacılar veya birinci sınıf üniversite öğrencileri bu yaklaşımı kullanarak, envanter problemlerine daha kolay çözümler bulabilecektir.

THE DERIVATION OF PRODUCTION LOT SIZING WITH IMPERFECT QUALITY, INSPECTION AND REWORK USING AN ALGEBRAIC APPROACH

Abstract

Many researchers use traditional computing processes that take the first and second-order partial derivatives to obtain closed form mathematical equations for the optimal order quantity or the optimal production quantity. However, this paper provides an algebraic approach to solving the production lot sizing problem in an imperfect production inventory system where an inspection process is conducted during and at the end of production, and any defective items produced are either sold at a discounted price or reworked/repaired at a cost. Using this approach, practitioners or first-year college students who lack knowledge of differential calculus may be able to find solutions to inventory problems more easily.
