Specific customer demands and technical requirements lead to high engineering efforts for the control software of CPPSs, especially when following a clone-and-own approach to reuse, as is still common in industry. Utilizing systematic variability management to derive and configure control software variants from a product line could help to reduce the cost of developing and/or maintaining CPPSs. However, modeling CPPS variability is challenging as knowledge from multiple disciplines (e.g., mechanics, electrics, software) is needed, which is either implicit in practice or expressed in multiple heterogeneous engineering artifacts with diverse semantics. Furthermore, techniques commonly used to implement CPPS control software (e.g., graphical programming or modeling languages) do not have any formal mechanism to express variability. In this paper, we report on our ongoing efforts to create a multidisciplinary variability management approach for CPPSs, particularly CPPS control software. We designed our approach as an integrated approach providing configuration options based on related heterogeneous variability models from multiple disciplines. Our integrated approach can generate control software based on related domain-specific implementation artifacts.","PeriodicalId":193319,"journal":{"name":"Proceedings of the 26th ACM International Systems and Software Product Line Conference - Volume B","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115513246","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The number of dependencies in software systems is becoming a source of countless bugs and vulnerabilities. In the past, the product line community has proposed several techniques and mechanisms to cope with the problems that arise when dealing with variability and dependency management in such systems. In this paper, we present Advisory, a solution that allows automated dependency analysis for vulnerabilities within software projects based on techniques from the product line community. Advisory first inspects software dependencies, then generates a dependency graph, to which security information about vulnerabilities is attributed and translated into a formal model, in this case, based on SMT. Finally, Advisory provides a set of analysis and reasoning operations on these models that allow extracting helpful information about the location of vulnerabilities of the project configuration space, as well as details for advising on the security risk of these projects and their possible configurations.","PeriodicalId":193319,"journal":{"name":"Proceedings of the 26th ACM International Systems and Software Product Line Conference - Volume B","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126732059","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In product lines, managing the common and variable characteristics of these development artifacts typically involves feature models. Yet for high-tech systems, management is complicated by the large number of features and constraints. Using multiple feature models, each with a reduced number of features relevant only for specific artifacts, has been identified as a possible solution to deal with this complexity. However, to use multiple feature models effectively, the relationships among feature models need to be known. While several approaches that support multiple feature models exist, they do not explicitly provide concepts for representing structural relationships between features in different feature models. Explicitly documenting these relationships improves understanding of the complete variability model and supports maintainability of the variability model under evolution. In this study, we present two domain specific languages---one for relationship modeling, one for change analysis which enables users to express change impact analysis queries using the relationship modeling language terminology---, which we implemented in TReMAFeM, a tool for relationship modeling among feature models. Moreover, we demonstrate the use of the tool on the industry-related case of the Extended Twilight System product line and explain how it can be used to support typical change impact analysis scenarios.","PeriodicalId":193319,"journal":{"name":"Proceedings of the 26th ACM International Systems and Software Product Line Conference - Volume B","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124202564","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

During development, engineers often need to focus on a particular subset of features that is relevant for them. In such cases, it would be beneficial to hide other features and their implementation. During product configuration, requirements of potentially multiple stakeholders need to be considered. Therefore, configuration often happens in stages, in which different people contribute configuration decisions for different features. Moreover, in some cases, stakeholders want to share a set of products rather than a specific one. In all these cases, the necessary operation is the same: some features from the product line are assigned a value (e.g., via a partial configuration) while other features remain configurable. In this work, we propose a subset operation that takes a product line and a partial configuration to derive a subset product line comprising only the desired subset of features and implementation artifacts. Furthermore, we present, evaluate, and publish our implementation of the proposed subset operation within the FeatureIDE framework.","PeriodicalId":193319,"journal":{"name":"Proceedings of the 26th ACM International Systems and Software Product Line Conference - Volume B","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125744084","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While this kind of variability implementation can now be detected, visualization support such as VariCity helps architects and developers understand the implemented variability using a city metaphor. In this paper, we demonstrate VariMetrics-IDE, an extension of VariCity that allows to visualize multiple quality metrics (e.g., code complexity, test coverage) together with the variability implementations, while supporting navigation between the source code and the visualization in an IDE. This extension thus facilitates the identification of zones of variability implementations with variability debt.","PeriodicalId":193319,"journal":{"name":"Proceedings of the 26th ACM International Systems and Software Product Line Conference - Volume B","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132036279","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, we make use of the Quality Variability Model (QVM), based on Category Theory (CT), to redefine reasoning operations. We start defining and composing the six most common operations in SPL, but now as quality-based queries, which tend to be unavailable in other approaches. Consequently, QVM supports interactions between variant-wise and feature-wise quality attributes.
