Modern manufacturing is under ever increasing pressure to develop solutions for highly complex tasks. In order to maintain the business survival in a highly competitive environment, it is vital to obtain customer satisfaction, which requires developing products with shorter lifecycles and higher quality meanwhile to reduce the production costs. In order to achieve such objectives a paradigm has...

We compare two approaches for a Markovian model in flexible manufacturing systems (FMSs) using Monte Carlo simulation. The model which is a development of Fazlollahtabar and Saidi-Mehrabad (2013), considers two features of automated flexible manufacturing systems equipped with automated guided vehicle (AGV) namely, the reliability of machines and the reliability of AGVs in a multiple AGV jobsho...

 Background and Aim: During the past times people have used furniture as today. Along with the social welfare development and the importance of manufacturing efficiency, the importance of ergonomics and standardization in furniture became very clear so that, today it is well-known that not considering human factors in furniture manufacturing causes much human health problems. Due to the importa...

    Dynamic cellular manufacturing systems,   Mixed-integer non-linear programming,   Production planning, Manufacturing attributes   This paper presents a novel mixed-integer non-linear programming model for the design of a dynamic cellular manufacturing system (DCMS) based on production planning (PP) decisions and several manufacturing attributes. Such an integrated DCMS model with an extensi...

Scheduling problems play a big role in manufacturing and planning the production for increasing the production efficiency and assigning the resources to operations. Furthermore, in many manufacturing systems there is a physical space between stages that called intermediate buffers. In this study, a model is proposed for minimizing the makespan of a hybrid flow shop scheduling problem with inter...

This research aims at presenting a consolidated model of data envelopment analysis (DEA) technique and value engineering to select the best manufacturing methods for gate valve covers and ranking the methods using TOPSIS.To do so, efficiency evaluation indices were selected based on the value engineering approach and different manufacturing methods were evaluated using DEA technique.Finally, ef...

Over the last four decades of research, numerous cell formation algorithms have been developed and tested, still this research remains of interest to this day. Appropriate manufacturing cells formation is the first step in designing a cellular manufacturing system. In cellular manufacturing, consideration to manufacturing flexibility and productionrelated data is vital for cell formation....

Introduction: Health and safety in cloud-based manufacturing systems have become a major issue, especially with the spread of the Corona virus, putting both systems and the workforce at risk. In recent years, many journals and researchers have focused their research in this area. Therefore, the purpose of this study is to systematically review health and safety issues in cloud manufacturing sys...

This paper investigates the transfer and implementation process of advanced manufacturing technologies (AMTs) in developing countries using the Cypriot manufacturing industry as a case study. Specifically the paper addresses: (1) the management processes followed during the transfer of technology into the manufacturing environment, and (2) the steps followed both before and after implementation...
