In our research in this area, with data from open source projects as well as an industrial partner, we noticed several shortcomings of conventional data mining approaches for classification problems: (1) Domain experts’ acceptance is of critical importance, and domain experts can provide valuable input, but it is hard to use this feedback. (2) Evaluating the quality of the model is not a matter of calculating AUC or accuracy. Instead, there are multiple objectives of varying importance with hard to quantify trade-offs. Furthermore, the performance of the model cannot be evaluated on a per-instance level in our case, because it shares aspects with the set cover problem. To overcome these problems, we take a holistic approach and develop a rule mining system that simplifies iterative feedback from domain experts and can incorporate the domain-specific evaluation needs. A central part of the system is a novel multi-objective anytime rule mining algorithm. The algorithm is based on the GRASP-PR meta-heuristic but extends it with ideas from several other approaches. We successfully applied the system in the industrial context. In the current article, we focus on the description of the algorithm and the concepts of the system. We make an implementation of the system available.</p></div>","PeriodicalId":36838,"journal":{"name":"Expert Systems with Applications: X","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.eswax.2020.100040","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74365395","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To improve the performance of the text classifier, we develop a novel neural network-based feature extraction method.

Processing times and setups depend on machine and job. The necessary resources could be: specific resources for processing, needed for processing a job on a machine; specific resources for setups, needed to do the previous setup before a job is processed on a machine; shared resources, understanding these as unspecific resources that could also be needed in both processing or setup. The number of scarce resources depends on machine and job. As an industrial example, in a plastic processing plant molds are the specific resource for processing machines, cleaning equipment is the specific resource for setups and workers are the unspecific shared resource to operate processing machines and setup cleaning equipment. A mixed integer linear program is presented to model this problem. Also a three phase algorithm based on mathematical exact method is introduced. Model and algorithm are tested in a comprehensive and extensive computational campaign. Tests show good results for different combinations of useE of resources and in most cases come to less than 2.7% of gap against lower bound for instances of 400 jobs.</p></div>","PeriodicalId":36838,"journal":{"name":"Expert Systems with Applications: X","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.eswax.2020.100022","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126549785","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Research builds several Data Envelopment Analysis (DEA) models (staged), and tests their connections with each other. Research concerns publicly traded manufacturing and trade companies of Finland and three Baltic States (Estonia, Latvia and Lithuania) during the years 2010–2018. Logical and in two stages proceeding DEA efficiency model gets statistical significance, and there is support that inventory and asset related measures will lead to revenue, profits and cash flow, which together will eventually result in higher shareholder value (like stated in operations and supply chain management theories such as theory of constraints). However, this finding has weakness as explanation power is low, and there is a lot of noise. It could also be so that inventories and assets are part of bunch of other inputs, which together directly create shareholder value. Therefore, it remains as an open question whether inventory and assets should be managed through classical and logical stages in companies through organization hierarchy, or if inventory and assets should be just a part of group of factors, which together aim to increase shareholder value.</p></div>","PeriodicalId":36838,"journal":{"name":"Expert Systems with Applications: X","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.eswax.2020.100027","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91974144","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Facing shortened innovation cycles, problem solving efficiency simultaneously constitutes a competitive factor. The purpose of this theoretical review is therefore the analysis of relevant approaches contributing to knowledge-based problem solving in physical product development, to synthesize a comprehensive construct as well as to derive novel conceptualizations. The latter demonstrably emerges from natural language processing, case ontologies and machine-/deep learning support, embedded in a distributed case-based reasoning architecture.
