Virtual Ecosystems for Smart Sustainable City-districts – an architecture perspective – Jesper Andersson

This talk will discuss architectural issues concerning establishing and operating a digital ecosystem. Digital ecosystems are becoming a foundation for value streams in multiple businesses and domains. The case we study is a smart-district platform, which shares challenges with the Smart-city.

This talk focuses on two concerns, the ecosystem’s platform architecture and architecture barriers to establishing and operating an ecosystem. We characterize sustainable product and service ecosystems in a smart-district ecosystem and discuss specific design alternatives. In a design process, certain architectural barriers impede ecosystem establishment and operation. We describe some categories with concrete examples from the case. In connection to the barriers, we describe specific architectural governance challenges and discuss some possible solutions. We discuss several avenues for future platform architecture and governance research.

Self-adaptation: basic principles and industrial usage – Danny Weyns
 
Self-adaptation enables a software system to reason about itself at runtime and adapt itself to realise a set of quality goals. Self-adaptation has been widely used in the software industry, but not necessarily known under the term self-adaptation. In this talk, I motivate the use of self-adaptation, outline the basic principles of self-adaptation, and report the results of a large-scale survey with practitioners on the use of self-adaptation in industry.

Title: Technology integration is about trust

Abstract:

We started our research project with a baggage of expectations about what we could do with data in compulsory education. Even greater expectation was reflected by the school principals we were working with. “Can we see this? And can we see that?”: asked the principals.

Two years after we started the project, we are standing on the finish line but have not crossed it yet. This means that we have not been able to “really” analyze (any which way) the data to create useful visualization dashboards. But we have learned a hack of a lot!
1. No data standards on site!
2. Digital inheritance is enormous!
3. Everyone develops as they please!
4. Competences are not at the top!
5. GDPR scares the “#€% out of everyone!
6. Local IT infrastructure is not in place!
7. OMG how many hours of dialog it took to get where we are today!
8. It is not about technology. It is about trust!

I will show you what we can do with the data, at this point in time only theoretically. I will also show you the technical infrastructure that Artemis, my doctoral student working with the data, has setup for integrating multiple datasets coming from different companies and schools. If you have experience of working with educational data from the primary school sector, I would also like to hear from you about ideas for future direction.

When? Friday October 6th 14-16

Bridging the Gap: A Hybrid Recommendation System for E-Commerce Cold Start Challenges – Kailash Chowdary Bodduluri, Industry PhD-student HL Design

Abstract: In the dynamic landscape of e-commerce, effective recommendation systems play a pivotal role in enhancing user experiences and boosting sales. However, the ubiquitous cold start problem has long been a challenge in implementing recommendation systems, particularly for businesses like HL Design that provide smart webshops to e-commerce customers. To address this challenge, extensive research was conducted through a systematic literature review on hybrid recommendation systems in the e-commerce domain. This review aimed to identify existing algorithms in the literature and uncover potential areas for adaptation. The literature review revealed some existing research gaps in the context of dealing with cold start issues. To bridge these gaps, a novel hybrid recommendation system was developed. This system leverages product images and descriptions, identifies similar products based on user sessions, and incorporates historical sales data. By combining these diverse data sources, the developed system offers innovative solutions to tackle the persistent cold start challenges in recommendation systems. This seminar will delve into the journey of identifying these research gaps, developing the hybrid recommendation system, and exploring its effectiveness in addressing cold start issues. It promises to be an enlightening discussion for those navigating the complex realm of recommendation systems in e-commerce.”

Continuous Performance Management of Business Processes via Digital Twin and Model-Driven Architecture – Samuele Giussani, PhD student at LNU

Business Process Management (BPM) deals with administrating the chains of events, activities, and decisions that add value to an organization. It is of particular interest to assess the business process performance in a continuous way, in order to gather as much information as possible to allow informed decisions in the value chain.

However, organizations are often complex and driven by several business-critical processes, that should be continuously monitored, evaluated, and managed to deliver value-added products and services to customers. To this end, we employ a Digital Twin of the Organization (DTO), which is a virtual representation of the organization that includes all the actors and activities implementing the business processes, to estimate and analyze the relevant Key Performance Indicators (KPIs).

The notation commonly adopted in BPM is distant from what a DTO can use to produce its results, so we introduce Biz2Sim, a model transformer tool that leverages the Model-Driven Architecture (MDA) approach to obtain simulation models from the Business Process Model and Notation (BPMN). By incorporating both Biz2Sim and the DTO in the traditional BPM lifecycle, performance assessment can be performed with real-time data and with an increased degree of automation.

Professor Mauro Caporuscio will give a seminar on September 22nd 14-15 about Green Software by Design. It is possible to attend the seminar either onsite or online. If you are interested in joining please send an email to diana.unander@lnu.se.

Abstract
Despite the media interest in sustainability, the public is still unaware that software, including digital assistants, cryptocurrencies, audio/video streaming services, finances, and games, are predicted to account for as much as 14% of the total worldwide carbon footprint in the next decade. Indeed, all software consumes electricity. In general, people think electricity is clean. Still, since most electricity is produced through burning fossil fuels (e.g., coal, oil, and natural gas), in practice, electricity is the single most significant cause of carbon emissions worldwide. Further, all the devices we use for running software (from our smartphones/computers to network appliances, and to cloud infrastructures) produce carbon when manufactured and disposed of (once they reach the end of life). The two most effective ways to reduce the carbon emissions of software are through Energy efficiency, and Hardware longevity. Unfortunately, current software development projects usually treat these concerns as an afterthought: a desirable quality to be considered if and only if other stakeholder- and economy-centered requirements (e.g., performance, business needs) have been successfully addressed. To face this unsustainable trend, we need a paradigm shift in the way we engineer and operate software systems. Indeed, the software shall be designed from the foundation to be green.

The aim of this talk is to bring these aspects to your attention and to hint at future research directions toward the reconciliation of three different and typically conflicting aspects: (1) efficiency: the ability to limit energy consumption, (2) longevity: the ability to live long and prevent hardware obsolescence, and (3) efficacy: the ability to meet the users’ expectations.
