“…Manzini et al [4] and Ferrari et al [5,6] discuss the importance of flexibility, i.e., the ability of a system to adapt to changing market demands in terms of both product variations or changes (capability flexibility) and product quantity (capacity flexibility). Consequently, the importance of flexibility is progressively emerging in inventory management and in picking activities (in particular in automated S/R systems).…”

Automated storage/retrieval systems (AS/RSs) are a combination of equipment and controls which automatically handle, store and retrieve materials (components, tools, raw material and subassemblies) with great speed and accuracy. Consequently, they are widely used in industrial companies to manage products with cost-effective utilization of time, space and equipment. This paper presents a multi-parametric dynamic model of a product-to-picker storage system with class based storage allocation of products. Thousands of what-if scenarios are simulated in order to measure the impact of alternative design and operating configurations on the expected system performance and to identify the most critical factors and combinations of factors affecting the response of the system. Class based storage proves to be a very effective way of both reducing the picking cycle time and maximizing the throughput of the system. The rapid effectiveness of visual interactive simulation (VIS) in supporting the design (redesign) and control of new (existing) warehouses emerges, responding to the need for flexibility which modern companies need in order to adapt to strongly changing operating conditions quickly

“…Considering automated flexible production systems as flexible manufacturing systems (FMS) and flexible assembly systems (FAS), they are commonly composed of two main sub-systems: the feeder system that feeds parts to work and the working station. While the working station is often designed at the present time to replace rigid automatic machines with programmable robotic systems [4,5], more attention should be paid to the feeder systems. In fact, the separation, singularization, and orientation of parts at the pick-up location is critical for both the overall flexibility and productivity [6].…”

Automation is a powerful way to reduce production costs. The growing market demand for a wide set of models and small batch production make flexible automated production systems an emerging need in several industries. The aim of this paper is to analyze and to maximize the performance of robotized flexible production systems consisting of a robot, feeder, working station, and unloading station, where the operations of the working cycle are scheduled using a sequencing algorithm based on priority rules. Since the working cycle is not predefined, the cycle time is strongly influenced by the parameters characterizing the workcell such as the workcell layout, the robot transfer movements, the feeder, the working operations, and the presence of a buffer between stations. In this work, we modeled the working cycle of a simple but representative layout of an industrial robotized flexible production system with and without buffer, and we implemented a recursive algorithm to estimate the cycle time. The analytical model derived was compared to the experimental results, obtained by using a prototype of the flexible production workcell. The results show that the analytical model is a powerful tool to estimate the performance of the workcell and to identify the design variables or their combinations that maximize the throughput

“…According to several authors (Edmondson and Redford, 2002;Yu et al, 2003;Hu et al, 2011), assembly is one of the most cost effective approaches to high product variety. However, today's assembly systems are increasingly required to quickly adapt to changing market requirements (Manzini et al, 2004).…”

AbstractPurpose -The purpose of this paper is to develop and test a design approach based on the investigation of the sensitivity of assembly systems to volume fluctuations as part of the selection process of alternative design solutions for scalable assembly systems on the basis of a real industrial case study. Design/methodology/approach -A conceptual approach for the (re-)design of a scalable assembly system is developed on the basis of an industrial case research using axiomatic design (AD) for the top level structuring of the framework incorporating useful methods and insights obtained from a thorough literature review and from previous research work. Findings -The findings of this research are limited due to the focused nature of a case study based research. However, the obtained results encourage assuming its transferability to similar problems. Originality/value -Significant research has been done in the design of assembly systems for high product variety, but the review of literature in this field still identifies many opportunities for future research. This paper responds to the clearly identified research need of a methodological guidance regarding the design of scalable assembly systems and offers a practically proven help to improve the efficiency of the design process and the quality of the design results.
