An Improved PAC Architecture for Shop Floor Information System in Digital Manufacturing

In order to overcome the weakness of the former production activity control (PAC) architecture, this paper presents an improved PAC architecture. The BIT-PAC architecture has been applied with the use of information technology. It facilitates the information flow from Shop Floor to other areas of the organization and makes the organizations more integrated and productive. This architecture also facilitates the expansion of the Shop Floor functions without disturbing the basic infrastructure. Effectiveness of the BIT-PAC architecture was checked by developing and running application software on a network PC which has supported the dynamic flow of information from Sub-Producers and Sub-Movers to other areas of organization.

Shop-floor resource virtualization layer with private cloud support

Large scale emergence of mature cloud solutions, ranging from software-as-a-service based solutions for business management, to very sophisticate private cloud solutions; offer the building blocks for constructing extremely flexible enterprise systems that can respond to environmental changes with great agility. Manufacturing enterprises need to adopt these new technologies to advance in a new era of mass customization where flexibility, scalability and agility are the differentiating factors. In this context, this paper introduces the virtualized MES and shop floor architecture as an intermediate layer in the manufacturing stack and discusses the advantages offered by this approach for manufacturing enterprises. A classification of MES and shop floor devices is presented focusing on the virtualization techniques suitable for each device type, considering the level of distributed intelligence and the virtualization overhead. Shop floor virtualization through shop floor profiles is presented and discussed underlying the flexibility of the solution. A pilot multi-agent implementation for virtual shop floor configuration based on the CoBASA reference architecture is presented and discussed. The shop floor profiles which define the virtual layout and mappings of the robotized manufacturing system are also provided in this context. The pilot implementation using six Adapt robots and a IBM CloudBurst 2.1 private cloud, is described and virtualization overhead in terms of event propagation delays is measured and presented in several scenarios of resource workload collocation on physical cloud blades     

My‐Mini‐Pet: a handheld pet‐nurturing game to engage students in arithmetic practices

In the last decade, more and more games have been developed for handheld devices. Furthermore, the popularity of handheld devices and increase of wireless computing can be taken advantage of to provide students with more learning opportunities. Games also could bring promising benefits – specifically, motivating students to learn/play, sustaining their interest, reflecting their learning/playing status, and facilitating the learning/playing progress. However, most of these have been designed for entertainment rather than education. Hence, in this study we incorporate game elements into a learning environment. The My‐Mini‐Pet system is a handheld pet‐nurturing game environment, in which students learn with an animal learning companion, their My‐Mini‐Pet. Three design strategies are adopted. First, the pet‐nurturing strategy, which simulates the relationship between the pet and its owner, the My‐Mini‐Pet becomes a motivator/sustainer of learning. Second, the pet appearance‐changing strategy, which externalizes the learning status of the student. In other words, the My‐Mini‐Pet plays the role of a reflector. Third, the pet feedback strategy, which links the behaviours of the student and his/her pet, the My‐Mini‐Pet acts as a facilitator of learning. A pilot study was also conducted to preliminarily investigate the effectiveness and experiences of the strategies on allowing the student to understand arithmetic practices. The results showed that the strategy was effective, encouraging the students to engage in learning activities. Furthermore, the game attracted the students’ attention and stimulated discussion between peers. Some implications about the further developments are also discussed.     

Production Control of a Flexible Manufacturing System in a Job Shop Environment

This paper provides an application oriented analysis of local search procedures for Operation Scheduling and Shop Floor Management of a major German manufacturer of cigarette machines. The heuristics applied are the Threshold- and Simulated Annealing-Algorithm considering Job Shop as well as embedded FMS production features. In this context a new neighbourhood search technique is developed, which is based on a small set of local neighbourhoods and is flexible with respect to the performance measurements of production control. By this approach the scheduling, loading and workload allocation problems of a production facility consisting of an embedded FMS and a conventional Job Shop can be solved simultaneously.
