KES - Discusys: Multiple User Real-time Digital Sticky-note Affinity-Diagram Brainstorming System
Procedia Computer Science, 2020Co-Authors: William Widjaja, Keito Yoshii, Kiyokazu Haga, Makoto TakahashiAbstract:Abstract Traditional-based brainstorming using sticky notes has been an integral part in many collaborative group discussion envi- ronment.Yet, despite the advancement in technology and the increased research effort to use technology to support group brainstorming, many groups still continues to relies on conventional paper-based discussion methods to generate, structure and communicate their ideas with each other. Discusys is a discussion support system that aims to augment the participants capabilities in group brainstorming by implementing 1. separation of private and public area during initial idea generation to allow ideas to mature without judgment of others 2. quick input and navigational design to help users to create, edit, view and manipulate the group generated ideas. 3. multi-platform synchronization technology to create a real-time visual information of the current status of the discussions which can be accessed by multiple users. Discusys utilized a dual-monitors PC client that separates the private and public dashboard, real-time network socket infrastructure to allow multiple users from different clients to interact with each other under one discussion ecosystem and multi-touch capabilities to create a natural, deep and structured collaborative discussion for multiple-users.

dads system distributed approach to digital Affinity Diagram collaboration
Proceedings of the 18th ACM Conference Companion on Computer Supported Cooperative Work & Social Computing, 2015Co-Authors: William Widjaja, Masayuki SawamuraAbstract:Affinity Diagrams are a popular method for creating and organizing ideas. While there are many digital solutions for collaborative Affinity Diagram, they have not been widely adopted due to usability challenges, so may teams still revert back to traditional method of sticky notes for their Affinity Diagramming activities. We proposed Distributed Affinity Diagram System (DADS) to solve the existing usability problems and present a more usable solution compared with the traditional method. DADS proposes a dual-screen terminal that divides private input screen from common interactive screen in each user's setup. While private input encourages users to create and nurture ideas, common interactive spaces are designed to sync all users' actions across all terminals, allowing users to collaborate interactively through a distributed multi-touch system. The separation of input space and the distributed synchronized interactive space can improve usability, efficiency, and user satisfaction.

efficient group discussion with digital Affinity Diagram system dads
Cooperative Design Visualization and Engineering, 2014Co-Authors: William Widjaja, Keito Yoshii, Makoto TakahashiAbstract:Collaborative discussion is an integral part of exchanging ideas and solving important problems. However, traditional approaches to group discussion have used analog tools that create problems for collaborative contributions. Many researchers have tried to use technology to overcome these limitations, but current digital collaboration systems isolate users from each other and do not promote efficient idea creation or allow users space to support ideas with evidence. The Digital Affinity Diagram System (DADS) presents a solution that encourages better group discussion by implementing three features: 1) Separation of private and common areas during initial phase to allow ideas to mature without initial critique 2) Intuitive input and navigational design to help users create, edit, view and manipulate generated ideas, and 3) Multi-platform synchronization technology to create real-time visual feedback on the discussion accessible to all users. DADS’ dual-monitor setup uses real-time network socket infrastructure so that multiple users can interact with each other under one discussion environment. We capitalize on multi-touch hardware to create a natural, deep and structured collaborative environment.

bring your own device ubiquitous approach to digital Affinity Diagram collaboration
Ubiquitous Computing, 2014Co-Authors: William Widjaja, Masayuki SawamuraAbstract:The rise of ubiquitous computing has simplified our lives by providing relevant information and tools wherever we are. However, technologies that allow collaboration between different form-factor devices are rare. While ubiquitous devices might serve individuals well, they don't support high levels of collaboration. We propose a system where groups can participate in onsite brainstorming using various form-factor devices: tablet, laptop, or desktop for collaboration. We utilize socket server technology to achieve a high level of synchronization for all individual actions during brainstorming. High rates of synchronization for real time collaboration is the key for usability and adaptability. Our system uses a method called Affinity Diagramming in which users illustrate, group and link their ideas to create an easily understood structure. Using ubiquitous devices - both mobile and stationary - in brainstorming can help teams work together to share resources, exchange and organize ideas to build solutions that enhance our lives.

Supply Chain Management Under Fuzziness - Investigating Organizational Characteristics for Sustainable Supply Chain Planning Under Fuzziness
Supply Chain Management Under Fuzziness, 2014Co-Authors: Anjali Awasthi, Katarzyna Grzybowska, Mohammad Hussain, Satyaveer Singh Chauhan, Suresh Kumar GoyalAbstract:Sustainable supply chains are essential to sustain modern business growth and ensure healthy market environment. In this chapter, we address the important characteristics that constituent organizations of supply chains should possess in order to achieve the social, economic and environmental objectives of sustainability. These characteristics (criteria) are obtained using Affinity Diagram. Then, a committee of decision makers is formed to provide linguistic ratings to the candidate organizations (alternatives) against the selected criteria. The linguistic ratings are then transformed into fuzzy numbers and subject to multicriteria decision making technique called VIKOR for sustainability assessment of organizations. A numerical illustration is provided to demonstrate the applicability of the proposed approach.

a hybrid approach integrating Affinity Diagram ahp and fuzzy topsis for sustainable city logistics planning
Applied Mathematical Modelling, 2012Co-Authors: Anjali Awasthi, Satyaveer S ChauhanAbstract:Abstract City logistics initiatives are steps taken by municipal administrations to ameliorate the condition of goods transport in cities and reduce their negative impacts on city residents and their environment. Examples of city logistics initiatives are urban distribution centers, congestion pricing, delivery timing and access restrictions. In this paper, we present a hybrid approach based on Affinity Diagram, AHP and fuzzy TOPSIS for evaluating city logistics initiatives. Four initiatives namely vehicle sizing restrictions, congestion charging schemes, urban distribution center and access timing restrictions are considered. The proposed approach consists of four steps. The first step involves identification of criteria for assessing performance of city logistics initiatives using Affinity Diagram. The results are four categories of criteria namely technical, social, economical and environmental. In step 2, a decision making committee comprising of representatives of city logistics stakeholders is formed. These stakeholders are shippers, receivers, transport operators, end consumers and public administrators. The committee members weight the selected criteria using AHP. In step 3, the decision makers provide linguistic ratings to the alternatives (city logistics initiatives) to assess their performance against the selected criteria. These linguistic ratings are then aggregated using fuzzy TOPSIS to generate an overall performance score for each alternative. The alternative with the highest score is finally chosen as most suitable city logistics initiative for improving city sustainability. In the fourth step, we perform sensitivity analysis to evaluate the influence of criteria weights on the selection of the best alternative. The proposed approach is novel and can be practically applied for selecting sustainable city logistics initiatives for cities. Another advantage is its ability to generate solutions under limited quantitative information. An empirical application of the proposed approach is provided.
