The feedback on the implementation of Lean confirms a gap between the “real work” and “prescribed work” and a negative impact of Lean on employees in terms of stress. These results allow considering in practice, ergonomic interventions to ensure the effective functioning of Lean while preserving the mental health and safety of operators.
This paper describes the evolution of e-business in B-to-B manufacturing small and medium enterprises. Based on the e-business initiatives that were resulted in previous work, this paper explains the empirical evidence through three separate studies that are complementary. First, this paper presents the initial allegations of e-business evolution. Second, a quantitative study is conducted to see whether...
The design and development of product service systems (PSS) is a complex process that brings together product, software and service engineering. A fully integrated PSS calls for significant collaboration among the different engineering disciplines along the entire design and development process which can pose several challenges to the development team. Therefore, when developing a PSS, companies should...
In this regular session the operations and lean problems are discussed with regards to many projects on the following topics: Some topics developed in this session: • Lean, Cognitive Ergonomics; • Operation Management System; • Flexibility, Scheduling problem; • Performance, Production strategy.
If companies want to tackle increasing complexity, they often take use of modular system architectures which are seen as important enabler for sharing standardized modules across different development projects. Although numerous examples in systems business can be found where companies established modular architectures, they still face difficulties to reuse standardized architectural elements in a...
In this paper, we will give a short overview about the complexity and the challenges of basic steps when building a Data Mining System. Such a work cannot be realized without empirical experience. For this reason the essence of many projects has found its way into this paper. After the introduction that explains premises of Data Mining that are often underrated or ignored, it is said, that one of...
In previous work, code smells have been adapted to be applicable on spreadsheet formulas. The smell detection algorithm used in this earlier study was validated on a small dataset of industrial spreadsheets by interviewing the users of these spreadsheets and asking them about their opinion about the found smells. In this paper a more in depth validation of the algorithm is done by analyzing a set...
This paper presents a prototype for a risk project management game template (PrimaGate). The template was developed in order to offer instructors and learners a flexible tool to build or adapt project risk management games that could be included as part of the curriculum to teach project management. The core focus of the design was to create a learning environment that facilitates the involvement...
Refactoring is often treated as the main remedy against the unavoidable code erosion happening during software evolution. Studies show that refactoring is indeed an elemental part of the developers' arsenal. However, empirical studies about the impact of refactorings on software maintainability still did not reach a consensus. Moreover, most of these empirical investigations are carried out on open-source...
Software Development for Automotive Systems is becoming more and more complex. Cars are turned into software intensive and to some extent software defined products by the increasing functionality of the various electronic control units (ECUs). Major driving factors for this development are complex human-machine-interfaces (HMI), eMobility and autonomous driving. Consequently, developing the software...
Companies formalize software processes as a way of organizing development projects. Since there are differences in project contexts, a one-size-fits-all approach does not work well in practice. Some companies use a family of a predefined processes, but this approach has a high process maintenance cost. Instead, we define Software Process Lines (SPrL), where a general process with variability is tailored...
Megamodels are often used in MDE to describe collections of models and relationships between them. Typical collection-based operations - map, reduce, filter - cannot be applied directly to megamodels since these operators need to take relationships between models into consideration. In this paper, we propose adapted versions of these operators, demonstrating them on four megamodeling scenarios. We...
Process mining is a technique that aims to gain knowledge of the event log. The amount of data in the event log is very influential in the Process mining, because it contains millions of activities that shape the behavior of a company. The three main capabilities possessed by mining process is a discovery, conformance, and enhancement. This paper, we present an approach to decompose business processes...
Studies conducted in recent years have indicated that the innovation behaviors of a company is determined by its knowledge attributes. Research conducted on these topics has mainly focused on the manufacturing industry, and limited emphasis is placed on service-oriented industries such as the information service industry. Most of the companies in the information service industry are small and medium-sized...
Flexibility and adaptability of production systems are still some of the most discussed characteristics of production systems within the traditional manufacturing industry. Because of increasing complexity and dynamics within the corporate environment, some approaches to optimize these traditional characteristics are no longer sufficient to achieve competitive advantages. The ongoing paradigm shift...
Increasing product variety and high cost pressure are significant challenges for manufacturing companies. One approach to face the dilemma between economies of scale and scope is the development of product architectures. This implicates new challenges for both development process and organization. Defined processes and roles are necessary to support product architecture development. A recent survey...
The Engineer-To-Order business encompasses companies producing a broad range of industrial products. Projects in this business are becoming increasingly complex, both from a technical and a management perspective. In this context, standardization programs have become a common approach to improve competitiveness and profitability of ETO companies. Standardization programs have their origin in the product...
Commercial advertisement dissemination is one of the most promising applications in self-organizing mobile social networks (SMSN). Lightweight incentives are essential to encourage the participation of mobile users, given that only a few users are voluntary due to limited resources in mobiles. However, existing incentives overlook dishonest behaviors of relays in overstating their costs for higher...
Service Oriented Architecture (SOA) is seen as a powerful ICT (Information and Communication Technology) paradigms nowadays. Empirical studies and literature review have revealed that the decision about adopting the SOA approach for a given business demand relies essentially on the ICT manager's experience and knowledge, which increases even more the risks that can affect the SOA implementation life...
The LogisticsHub is an event tracking solution to manage information of cargo carrying units (CCUs) and their content along the upstream oil and gas supply chain. The main objective is to facilitate the best possible flow of information between the companies in the oil and gas sector related to offshore upstream oil exploration and production activities. The LogisticsHub uses the EPCIS (Electronic...
