Özet (Çeviri)
Nowadays, all logistics firms aim to optimize their ability of innovation in order to survive in a competitive market. Innovation contributes to their development through the generation of new concepts, which in turn generate higher profits. This thesis project discusses and demonstrates in detail an innovative approach for the industrial transportation of lightweight goods based on developed overhead conveyor model concepts including their design features, operational specifications and software simulation results regarding both mechanical and logistical properties. Ultra-light overhead conveyor systems are rope-based systems with individually driven vehicles. The vehicles can move automatically on the rope as this system works through independently built-in energy sources and signals. Five different conceptual models of ultra-light overhead conveyor systems are represented and their components are explained in this study. These models are created based on the technical characteristics of the individual components. Through the CAD Software, models are visualized. After comparing these models, the best one is then selected and described in detail. Necessary Finite Element Method analyses for the selected model are then executed. These analyses help with the calculation of critical stress and displacement limits of structures under force load. The process of an ultra-light overhead conveyor system is then analyzed using necessary assumptions. The analysis consists of three scenarios. These scenarios are based on increasing the vehicle speeds with equal increments in each case. The correlation between vehicle speed and system throughput is investigated. A discrete event simulation model of the system is constructed using the DOSIMIS-3-software to translate these three scenarios. The objective of this work is to illustrate the logistical implementation of the selected model. This model does not represent a final design operating in a real life scenario. This model is solely designed to give an overview of this new approach for future research which would definitely help companies attain lower development costs as well as quicker market maturity. According to the selected model necessary revisions will be made and a new model will eventually be applied in real life scenarios.
