Material handling is one of major components in Flexible Manufacturing System (FMS). Any improvement of material handling capability is to affect the performance of the whole system. This paper discusses the simulation study on the effect of part arrival rate and dispatching rules to the average waiting time and production rate of the FMS. The facilities of the system were modeled into simulation environment by using Arena Simulation Software. The production parameters such as machine processing times, part transportation speed and type of products were put into the model to represent the behaviors of the real system. Two rules have been considered in the study, i. e. first come first served (FCFS), and shortest processing time (SPT). Average waiting time and productivity were taken into account as performance measures of the system. The result of the study showed that SPT rule gives shorter average waiting time and higher productivity. Based on this result, the SPT rules would be used to control part transporter in order to have a better performance of the FMS.

The current works deals with the design and development of an Automated Storage and Retrieval System (ASRS) machine for Flexible Manufacturing System (FMS). The work involved investigating ASRS machine features and operating procedures, evaluating related hardware, software and communication modules for the machine. The work explored on the different options of hardware and software modules offered in the current market and further selected the suitable one for the ASRS machine development. Several design considerations and the limitations faced during the process of the project development and implementation are given. Arduino was used as the coding system for the Arduino UNO board while stainless steel 305 and aluminium was used as the main frame in fabricating the ASRS machine. Lastly, a final working prototype of a fully-developed ASRS machine with dimensions of: 80cm by 73cm by 94cm (length by width by height) is presented.

The Impact

This paper discussed job shop scheduling considering material handling process. This process is a very important aspect on a flexible manufacturing system, where raw material or semi-finished goods are delivered from one processing point unto another by utilizing automated material handling equipment, functioned as shared resources. The starting time of each process is affected by the ability of the material handling equipment to conduct timely delivery from one point to another, therefore considering this process unto scheduling is important to enable planner to get precise estimation of the process makespan. We take the case where the flexible manufacturing system is consisted of four identical machines; each has the capability of processing various jobs due to the various cutting tools installed on their tools magazine. Jobs are dispatched based on longest processing time rule and then allocated to machine which has minimum load. Being a shared resource, material handling equipment has pick-up and delivery priority rule when handling multiple requests. The two most common rules are longest waiting and closest entity. This paper will analyzed the impact of each rule to the process makespan and material handling equipment utilization. Simulation model were built using Promodel to give decision maker better visualization of the system under consideration.

Main Model

Scheduling Flexible Manufacturing System (FMS) can increase production speed and accuracy. It because FMS has an ability to process various variety of product at same work station. However, FMS need efficient allocation of resources, for example: allocation of material handling equipment. This paper presents production scheduling FMS modelling to 24 jobs and 4 machines considering stacker crane. Coloured Petri Nets (CP-Nets) is the programming language which used to simulate model because it’s simplicity. This model consists two main model activities. The first one is Physical Activity (PA) which related to every activity that involve physical movement, including stacker crane processes. PA consist five CP-Nets models: loading/unloading station, stacker crane, machine, picking mechanism, and pallet stocker. The second activity is Logical Expression (LE) which related to the rules on how FMS should operate. LE consist three CP-Nets models: machine selection, pick-up request, and stage two procedure.  A simulation and numerical report show utilization level of all machines around 80-84% and stacker crane 8,74%.

Highly automated machine cell which is based on the principle of Group technology, comprising a group of processing work station for the production is referred to as Flexible Manufacturing System (FMS), where different processes like material handling, storage system, operation, inspection, etc., are interconnected by the automatic control unit. The concept of FMS (system 24) was first introduced in the mid-1960s to form a system that can operate 16 hours a day without any human attendant. The reason behind selecting this area for research is that there are problems like more lead time, inefficient utilization of machines, more space requirement in a machine shop, and high inventory level in the current manufacturing industry. All these problems can be solved by introducing automation in a manufacturing system, which can be done through FMS. FMS provides better resource utilization, high-quality control, low-cost product, a high rate of production, reduced direct labor requirement, and high labor productivity. Operational issues related to FMS faced by industries are machine loading, scheduling and dispatching, part routing, tool management, and part grouping so there is much scope of future development of FMS if all these issues are resolved.
