Design of Equipment Rack with TRIZ Method to Reduce Searching Time in Change Over Activity (Case Study : PT. Jans2en Indonesia)

Janssen is a manufacturing plant that works in furniture assembly. Component shortages often occurs, it will cause the increase of work in process (WIP) in assembly section. In previous studies, we analyze the root causes with FMEA and then it is resulted that router section is the constraint of the system. There are many non value added activities such as searching and transportation caused by a messy condition of work places and the devices that aren’t put in the right place. The impact is that the time allocated for every change over is higher than before. There are many components that are worked by the router section, so improvements are needed to minimize changes in over time. 5S method and the use of a new design of rack by TRIZ method are suggested for fixing the conditions of work environment. It is expected to eliminate non value added activities and changes in over time. Result shows that we can reduce non value activities in change over of regular components up to 41% and the elimination of this time is 41,6%. The non value activities in changeover of new items is 36,6% and this elimination of time is 53,3%. Key word : change over, kaizen, design, TRIZ metho

Effect of Office Ergonomics on Office Workers’ Productivity in the Polytechnics, Nigeria

The study was anchored on the ergonomic theory of production and design that stress the importance of office workstation as imperative for workers enhanced productivity. Quasi-experimental design was used to determine the relative performance of office workers with ergonomically fitted furniture, equipment and environment on their keyboarding tasks performance. The study lasted for three months with the post-test results indicating better performance from the experimental group. This implies that office workers with ergonomically fitted furniture, equipment and environment in the tertiary institutions in Nigeria are likely to have enhanced work output. Therefore, the institutions should be provided with well-furnished office with appropriate technological devices and environment.

LAYLAB : a constraint-based layout manager for multimedia presentations

When developing advanced intelligent user interfaces composing text, graphics, animation, hypermedia etc., the question of automatically designing the graphical layout of such multimedia presentations in an appropriate format plays a crucial role. This paper introduces the task, the functionality and the architecture of the constraint-based multimedia layout manager LayLab

Free/Libre/Open Source Software (Floss): Lessons for Intellectual Property Rights Management in a Knowledge-Based Economy

International audienceThe aim of this paper is to focus on the emerging situation in which open source software is nowadays produced not only by individual developers but in a growing proportion by firms that hire programmers for their own objectives of development in open source or for contributing to open source projects in the context of dedicated communities. As commercial firms it is important to analyze how and why they are capable of drawing benefits from such involvement and their connected activities. Moreover, we want to stress the different types of business model these firms rely on and the possible evolution they are likely to follow in the near future. We shown how Open Source principles provide an alternative way of thinking and managing intellectual property that do not come up against the same problems but needs a radical change in the way of drawing commercial benefits from knowledge development tasks. Then we analyze the growing involvement of commercial actors by setting up a typology of the different business models that can be observed in the OS landscape, how they correspond to the different strategies of industrial firms according to the main characteristics of their technical skills and market position. Finally, in a conclusive section we will draw the main lessons of the FLOSS experience for a possible enlargement of those principles of IPR management and business to other knowledge based commercial activities

The man/machine interface in information retrieval: Providing access to the casual user

This study is concerned with the difficulties encountered by casual users wishing to employ Information Storage and Retrieval Systems. A casual user is defined as a professional who has neither time nor desire to pursue in depth the study of the numerous and varied retrieval systems. His needs for on-line search are only occasional, and not limited to any particular system. The paper takes a close look at the state of the art of research concerned with aiding casual users of Information Storage and Retrieval Systems. Current experiments such as LEXIS, CONIT, IIDA, CITE, and CCL are presented and discussed. Comments and proposals are offered, specifically in the areas of training, learning and cost as experienced by the casual user. An extensive bibliography of recent works on the subject follows the text

Using graphical style and visibility constraints for a meaningful layout in visual programming interfaces

In the expanding field of visual applications, layout design and graphical editing tasks are crucial points. In this paper, we address the incorporation of AI aspects in the visual software design process and the automatic layout and beautification of informational graphics such as visual programs and chart diagrams. Since layout in dynamic settings frequently requires a direct manipulation responsiveness, an incremental redesign of the generated visual material is necessary. Following our previous work on constraint-based multimodal design, we show how powerful constraint processing techniques, such as constraint hierarchies and dynamic constraint satisfaction, can be applied to visual programming environments in order to maintain graphical style and consistency for a meaningful layout. We describe InLay, a system for constraint-based presenting and editing visual programs. Finally, we will have a short look at some extensions with regard to advanced interaction and visualization techniques

Prototyping with Monkeys: Uncovering What Buttons for Monkeys Look Like

Although much work has focused on designing touch interfaces for primates, little is known about how physical computer buttons for monkeys would look. Here, we employ the rapid prototyping method commonly used in human–computer interaction to design tangible buttons for monkeys allowing them to interact with computer enrichment. Our findings reflect on the process of altering rapid prototyping from humans to animals and how computer buttons for monkeys might look. On this basis, we make suggestions for monkey buttons, highlighting colour and pull/swing over push/touch interactions. We also reflect on lessons learned from transferring prototyping across species, such as the need to iterate on a few variables and for initial prototypes to be varied, and speculate on how to balance the designer (human) and user (animals) needs. More broadly, this paper builds upon HCI prototyping techniques for unconventional users, creating a method for rapid iterative prototyping with animals
