Dispatching Control

Material handling process on assembly lines is important because poor planning and control policies lead to low utilization of workforce and resources, which will cause more inadequate part delivery (part starvation) and reduce the overall system performance. Therefore, the delivery system must be optimized such that minimum number of workforce can be achieved without sacrificing production rate. In real assembly process, for better safety and higher efficiency, dolly trains are widely used to replace traditional forklifts for part delivery, which allows drivers to deliver more than one parts per trip and raises problems: how to choose proper number of parts and the delivery order at the beginning of each trip to achieve optimal dispatching control. Effective algorithms and strategies are addressed and compared in this study to provide practical guidelines for dolly material handling system.

Material inventory management is one part of the logistics system devoted to project implementation on material procurement as per the needs plan procurement management is a very important material function, since the material inventory for a construction project involves a considerable investment cost. In general, every construction project involves complex activities, which involves the sharing of activities and operations. Material acquisition activities require good planning and control considering the large percentage of material costs to the total cost of the project. So if less effective material handling will result in loss of time, cost and quality. then this should receive high attention from contractors for the smooth and performance to be achieved in the implementation of construction projects.

Material Handling Systems

Advanced manufacturing systems allow rapid changes of production processes by means of reconfigurability providing mass customisation of products with high productivity, quality and low costs. Reconfigurable Manufacturing Systems (RMS) employ conventional as well as special purpose CNC machines, robots and material handling systems. In customised automated assembly, a number of different workpieces need to be processed simultaneously at various workstations according to their process plans. Therefore, a material handling system is an important part of RMS, whose main task is to provide reliable, accurate and efficient transfer of materials according to the process scheduling, without bottlenecks and stoppages. In this research, a reconfigurable pallet system was developed to facilitate automated robotic assembly for a highly customised production environment. The aim is to design a material handling system for conveying, sorting and processing of parts, which are supplied by robots and part feeders in different configurations. The developed pallet system provides a low-cost solution and it includes four flexible conveyors and part handling devices. All the elements of the system were successfully integrated with an intelligent controller. A user-friendly human machine interface provides easy reconfigurability of the pallet system and interfacing with robots, processing stations and part feeding sub-systems. The main advantages of the developed material handling system are the ease of operation, its reconfigurability and low-cost. The system demonstrates the advantages of reconfigurable material handling systems and it can be employed for training purposes.

The efficiency of intra-ship material handling system has a significant impact on naval ship operational effectiveness. Previous ship designs did not consider material handling systems very well. This paper focuses on material handling system as a man-machine-environment system, since material handling issues are global and complex. The methods of analysis and simulation are discussed, which are utilized for the operation process of material handling system. The optimization of operation process, transportation route and arrangement are then summarized. On this basis, the evaluation index system of material handling system is set up using Delphi method.
