Comparative Analysis of Traditional Production Systems with Flexible Manufacturing Systems

Nowadays technology is developing rapidly and the adaptation of emerging technology to daily life is very fast. Within this context, production technologies are developing rapidly and parallel to this production instrument's costs are decreased. In this way, producers can make investments more easily by getting current technology. In parallel with industrial development, some parameters such lost time, labor, raw materials must reduce. When considering expected product variety, especially modification on the produced product is a difficult process. Revising of the production system according to the final product is substantially increased the amount of lost time. In addition, in this revision process previously realized investment is becoming inert and this quite increases costs. It is almost impossible the creation of a separate production line for each product in a company which has a lot of variety of products. Nowadays in this needed speed production process, instead of conventional production systems flexible manufacturing systems began to be preferred in the industry. In this study, functions, components and the overall structures of the flexible manufacturing systems are described. Differences between traditional production systems and flexible manufacturing systems, and the advantages relative to each other were examined. In the study, Flexible Manufacturing Systems Laboratory within the Inonu University Arapgir Vocational High School was taken as an example.


Introduction
One of the major environmental factors that directly affect activity of the business is the economic system adopted by the country where the business [1].Industrial businesses are organizations that meet the demands of customers, carry out the production function for it.Businesses should develop and establish a proper system for needs when performing their production.Production Process is a process in which the materials are introduced as output after certain changes.Other processing activated where a process finished.As soon as a process starts the previous work is completed.Operations can be specified as a node and all the nodes constitute input-output system.[2]

Traditional Manufacturing Systems
The construction of traditional manufacturing systems is shown in Figure 1.It can be said to show a hierarchical structure of production systems.It is often used in the creation of this system is a hierarchical design approach.This approach can generate significant demand and limited production capability well in environments in which the solutions, but not enough.Classic hierarchical type of production structures, the not fully compatible with dynamic environment and leads to degradation in performance.

Flexible Manufacturing system
Flexible manufacturing systems is defined as the production process can respond, automation and technology-intensive production is done, can be quickly directed to the production of production factors, the products are delivered to customers on time and can be rapidly respond to changes [3].

Conclusion
In this study, images of the equipment, experiment sets are designed by Festo Didactic training purposes.Each module can be matched with other modules.In this way it is possible to obtain improved diversity of the final product.The manufacturing sector is constantly evolving according to evolving technology and growing needs.Requested product diversity has led to become outmoded of a single type production line.Therefore, instead of building new production lines to produce different types of the same product, revising this line is easier.In this regard with flexible production systems efficient results are obtained.Despite the high investment costs, in the long term it is seen that provided gain at costs and time.
