This paper describes a modular autonomous material handling equipment solution for flexible automation. Discrete event simulation is in this case used as a tool for shortening time spent in many different phases of a manufacturing systems lifecycle. The paper presents the concept of autonomous modular material handling equipment, and how simulation is used as a support tool and lead time reducer in each lifecycle phase. Furthermore, we describe the knowledge levels needed for using the simulation support and conclude with examples of how this methodology are reducing lead times within a company.

    • "By combining these units a modular automation system can be built to achieve reconfiguration. Typical examples include Component-Based approach proposed by Harrison et al for the design and implementation of modular assembly automation systems (R.Harrison et al, 2006), Actor-Based Assembly Systems (ABAS) built based on autonomous mechatronic units (Martinez Lastra, J.L., 2002) ,Modular Machine Design Environment (MMDE) (Moore, P.R et al, 2003) proposed and implemented in VIR-ENG research project for designing, implementing and verifying control systems for agile modular manufacturing machinery, a modular autonomous material handling equipment solution for flexible automation described in (Bj et al, 2004), a fully automated robotic system in a modular way to meet the needs of a high throughput chemistry laboratory described by Manley (Manley, J.D et al, 2008) and a modular approach for production system engineering by adopting mechatronic objects proposed by researchers from Daimler AG and the University of Magdeburg (M. Bergert, J.K, 2010). "

    ABSTRACT: To address the challenges in the automotive industry posed by the need to rapidly manufacture more product variants, and the resultant need for more adaptable production systems, radical changes are now required in the way in which such systems are developed and implemented. In this context, two enabling approaches for achieving more agile manufacturing, namely modular automation systems and virtual commissioning, are briefly reviewed in this contribution. Ongoing research conducted at Loughborough University which aims to provide a modular approach to automation systems design coupled with a virtual engineering toolset for the (re)configuration of such manufacturing automation systems is reported. The problems faced in the virtual commissioning of modular automation systems are outlined. AutomationML -an emerging neutral data format which has potential to address integration problems is discussed. The paper proposes and illustrates a collaborative framework in which AutomationML is adopted for the data exchange and data representation of related models to enable efficient open virtual prototype construction and virtual commissioning of modular automation systems. A case study is provided to show how to create the data model based on AutomationML for describing a modular automation system.

    ABSTRACT: Lack of standardization is often a key problem area limiting the applications of any new automated micro-handling technology, due to that equipment makers may have to spend an excessive amount of time and resources to customize automation solutions. Carrier-based material handling systems provide product-independent solutions. Product independency is an essential requirement for re-using material handling systems, because they allow product change without mechanical changes in the transport devices. This paper describes a new automated inter-machine material handling system for micro-manufacturing integration, based on the standard carrier DIN-32561. The main task of the system is to transport (full/empty) carriers between different stations/machines in a micro-manufacturing plant, to integrate assembly and manufacturing. The authors designed a conveyor belt and an automated guided vehicle system to fit into a linear pick-and-place micro-manufacturing plant. Prototypes of the different components were then developed and tested. KeywordsMaterial handling system-Micro-manufacturing-Standard carrier-Automation-Automated guided vehicles-Conveyors
