Ford model arabaların ilk üretiminden bu yana bir çok üretim modeliyle üretimler gerçekleştirilmiştir. Geleneksel montaj üretimi yapan her fabrika hareketli üretim bantları üzerine sistemi kurarak çıktının maksimum, maliyetlerin minimum olmasını ve çalışanların en verimli şekilde işletilmesini amaçlamaktadır. Seru üretim sistemi de 90’lı yıllarda en yeni üretim sistemlerinden biri olarak Japonya’da ortaya çıkmıştır. Canon ve Sony gibi dev Japon şirketleri Seru üretim sistemini ürün farklılaştırma ve markete daha çok yön verme hedefiyle uygulamışlardır. Seru üretim temelinde özellikle Türkçe literatürde yapılan çalışmalar oldukça az sayıdadır. Bu çalışmada seru sistemini geleneksel bir montaj hattı üzerine uyarlayıp kaynak kullanım oranlarının ve çıktı sayısının maksimize edilmesi amaçlanmıştır. Çikolata üretimi yapan bir fabrika üzerinde Arena yazılımı kullanarak Simülasyon tekniği kullanılmış ve alternatif hat-seru montaj senaryoları ortaya konmuştur.

Formulating line-seru conversion and scheduling problem simultaneously.  Trying to fill the gap in the existing literature.  Validating the proposed model with two numerical examples  Figure A. Seru types Purpose:The aim of this study is to propose a mathematical model for the conversion of the assembly line to the seru production system (line-seru conversion) and scheduling problems and also try to fill the gap in the existing literature. Theory and Methods:Companies such as Sony and Canon have developed a Japanese cellular manufacturing system to meet market demands and to distinguish it from the traditional cellular manufacturing system; they have called this production system a seru production system. In this study, a comprehensive literature review has been conducted. In addition, a mathematical model is proposed for line-seru conversion problem and scheduling problem that aims to minimize total tardiness. The proposed model has been solved for small-sized problems and the results are analyzed. Results:To validate the proposed model and show its efficiency and performance, The model has been implemented in the GAMS 24.1.2 modeling language and two numerical examples are solved by using COUENNE solver on a personal computer (Intel (r) Core(TM) i7-7700 HQ 2.8 GHz and 16GB Ram). The computational experiments indicate the efficiency of the proposed model. Conclusion:Among the various innovations of manufacturing systems, the conversion of the conveyor assembly line to seru production system has attracted great attention both in academic studies and production applications in recent years. However, research in this area is still limited. Especially in Turkish researches, the seru production system is very new and this study is the first study on the line-seru conversion problem. The most important contribution of this study is to propose a mathematical model for the line-seru conversion problem. Also, this study can be applied to assembly-based manufacturing companies. In addition, this work can be extended to the hybrid-seru production system. Due to the NP-hard property of this problem, in the continuation of this study, it is planned to develop heuristic or meta-heuristic algorithms to solve large-scale problems in a reasonable time.

Implementation of the fuzzy logic is a modern approach for cost-volume-profit analysis and decision-making process under risk and uncertainty (Yuan, 2009). The implementation of the fuzzy logic approach especially makes sense for profit or loss estimations in developing countries, where uncertainties and risks are often observed (Roztocki & Weistroffer, 2005). This study aimed to estimate the profit or loss of indirect Coombs blood test, which is among the 100 blood tests run by the laboratory department of a healthcare organization located in Istanbul, Turkey, that started operations in 2018. Another purpose of the research was to compare the profit or loss estimated by fuzzy logic with the actual values. Research questions of the study were: 1) Can fuzzy logic be used in the health sector’s profitability estimates? 2) What is the estimated success rate of fuzzy logic in the case of uncertainty and complexity? 3) If the fuzzy logic can be used in the health sector’s profit forecasts, how close are the estimated profit sums achieved by the fuzzy logic to the actual profit sums? Based on the findings of the study, profit estimated by the fuzzy logic is in a close range to actual values with a low error rate
