TL;DR: In this paper, a generic procedure model and a specification technique for the integrative development of mechatronic products and their production systems are presented, which can be used to deal with the stated problem.
Abstract: The increasing penetration of mechanical engineering by information technology enables considerable benefits. The arising new discipline is referred to by the term mechatronics, which expresses the close integration of mechanics, electrics/electronics, control engineering and software engineering. Hence, the design and production of such systems is an interdisciplinary and complex task. An effective and continuous cooperation and communication between developers from different domains during the whole development process is required. Moreover, the multidisciplinary and synergetic effectiveness of mechatronic systems as well as new production technologies cause strong interdependencies between system parts, which are to be produced. As a consequence, the production system determines the product concept. Restrictions by manufacturing technologies have to be considered already during the early stages of the product development. This contribution deals with the stated problem by providing both, a generic procedure model and a specification technique for the integrative development of mechatronic products and their production systems.

TL;DR: In this article, system dynamics models have been developed to study the complex interrelationships among various members in a collaborative supply chain to achieve effective and efficient engineering change management processes, and several standard templates have been used to address the complexity of the models.
Abstract: Engineering changes to products aim to correct design faults, exploit new market opportunities, improve overall product performance, or reduce production costs. These changes are thus considered as opportunities to stay competitive in the market place and companies strive to implement them in their products at the lowest possible costs. Such engineering changes in a collaborative environment require the original equipment manufacturer to work together with suppliers for designing, manufacturing, and marketing a product profitably. Simulation of an engineering change management process provides an understanding of important factors affecting the engineering change management process and helps in identifying any critical components of the entire process. In this research, system dynamics models have been developed to study the complex interrelationships among various members in a collaborative supply chain to achieve effective and efficient engineering change management processes. To address the complexity of the models, several standard templates have been developed and used.

TL;DR: The Engineering Cockpit is presented, a social-network-style collaboration platform for automation system engineering project managers and engineers, which provides a role-specific single entry point for project monitoring, collaboration, and management.
Abstract: Automation Systems Engineering projects typically depend on contributions from several engineering disciplines. While available software tools are strong in supporting each individual engineering discipline, there is very little work on engineering process management and monitoring across multi-discipline engineering projects. In this paper, we present the Engineering Cockpit, a social-network-style collaboration platform for automation system engineering project managers and engineers, which provides a role-specific single entry point for project monitoring, collaboration, and management. We present a prototype implementation of the Engineering Cockpit and discuss its benefits and limitations based on the feedback of our industry partners. Major results are that the Engineering Cockpit increases the team-awareness of engineers and provides project-specific information across engineering discipline boundaries.

TL;DR: An advanced production management principle, the New Japan Production Model to further advance TPS (Toyota Production System) called the Advanced TPS is proposed, which involves the systematization of Japanese production management methodology for strategic production as discussed by the authors.
Abstract: An advanced production management principle, the New Japan Production Model to further advance TPS (Toyota Production System) called the Advanced TPS is proposed, which involves the systematization of Japanese production management methodology for strategic production. The New Japan Production Model—a new management technology principle, proposed and verified in previous studies—was developed through establishing a Global Production Technology and Management Model based on New JIT utilizing three core technologies (TMS, TDS, and TPS), which relates to hardware systems, and Science TQM, which relates to software systems. Formation of the model through utilization of these core technologies signifies the high linkage of business processes that enables a speedy production cycle by using “Intelligent Quality Control System, TPS-QAS”, “Highly Reliable Production System, V-MICS”, “Renovating Work Environment, TPS-IWQM” and “Bringing up Intelligent Operators, V-IOS”. Effectiveness of the proposed New Japan Production Model was verified at Toyota Motor Corporation.

TL;DR: Important challenges for the development of distributed automation systems are identified and a holistic engineering approach is developed based on non-functional requirements derived from an information science point of view adapted to the specifics of automation technology.
Abstract: Industrial production plants are highly complex mechatronic systems. In today's automation systems a trend for distribution of control functions can be observed. The hereby emerging challenges lead to delays and interruptions in automation projects. Especially non-functional requirements are hard to specify for later engineering phases. Therefore, a holistic engineering approach will be developed. As a first step, important challenges for the development of distributed automation systems are identified in this paper. Based on this, non-functional requirements derived from an information science point of view are adapted to the specifics of automation technology.

TL;DR: A method is described which can be used to analyze the dependency of product properties and, thereby, product quality from engineering activities and it is described how this dependency can be controlled within the engineering process.
Abstract: Product quality is one key performance indicator for manufacturing systems with growing importance. Among others it depends strongly on manufacturing properties and parameters defined within the engineering process of the manufacturing system creating these products. Thus, manufacturing systems engineering quality directly influences product quality. To control the reachable product quality within the engineering process, the dependencies between engineering process, manufacturing system, and product have to be known and used within the engineering process as guidance. Within this paper a method is described which can be used to analyze the dependency of product properties and, thereby, product quality from engineering activities.

TL;DR: This chapter summarizes authors research in Mechanical Design Automation (MDA) domain during the last two decades up until the more recent issues related to storing, sharing and reusing of engineering knowledge, the role in PLM approach and the support to decision-making.
Abstract: Design activity consists, strictly speaking, in synthesizing something new (or arranging existing things in a new way) to satisfy a recognized need. This activity is accomplished through an iterative, knowledge-based, decision-making process. One of the goals pursued by IT applied to product development has been Design Automation that is the execution of all tasks of the design process of a product by a software application. In this context, engineering knowledge elicitation, representation and management are key issues to achieve the so-called “right the first time” design. This chapter summarizes authors research in Mechanical Design Automation (MDA) domain during the last two decades; it focuses the evolution from CAD centered applications to Object-Oriented (O-O) ones up until the more recent issues related to storing, sharing and reusing of engineering knowledge, the role in PLM approach and the support to decision-making. Finally, the fundamental aspects related to development of real-MDA applications are discussed, on the basis of personal experiences of the authors.

TL;DR: In this article, the authors proposed a new methodology of computer aided machine tools selection for focused flexibility manufacturing systems based on multi-criterion approach and allowed to select suboptimal sets of machine tools with the right level of flexibility required by the specific production problem.
Abstract: This paper proposes a new methodology of computer aided machine tools selection for focused flexibility manufacturing systems. The methodology is based on multi-criterion approach and allows to select suboptimal sets of machine tools with the right level of flexibility required by the specific production problem. In the selection process, we first consider critical decision criteria which directly decide if a given machine tool is suitable to realize a defined production task and complies with conditions specified by the designer. Furthermore, economic considerations are taken into account in order to find the best solution from the viewpoint of minimization of both investment costs and time of machining. An illustrative example of machine tool selection using the proposed methodology and the software implementation is also provided.
TL;DR: In this article, a balance of mixed management and engineering concepts that fuse classical engineering methodologies into a systems engineering framework to assess and compare systematically and comprehensively services rendered by engineering systems is presented.
Abstract: Purpose – This paper aims to be a balance of mixed management and engineering concepts that aims to fuse classical engineering methodologies into a systems engineering framework to assess and compare systematically and comprehensively services rendered by engineering systems.Design/methodology/approach – An auditing framework is developed to assess the performance of engineering services in the context of engineering services found within a facility. As a result of a system heterogeneity factor, an approach to remove this confounding issue is developed to provide a different insight into the performance of engineering services.Findings – The output of the audit exercise serves as an input to the second methodology, direct age‐adjusted failure, which overcomes systems attributes confounding issues when comparison is made between different systems populations of the same class type. This method allows management to identify areas in which extra resources are needed to improve maintenance performance.Practic...
TL;DR: The problem of Earth environmental destruction by human activities is becoming dangerous as discussed by the authors, which is why the understanding of ecological problems is essential for people responsible for production and industrial design, and that is why they should be well aware of the negative influence of their activities on the state of the planet.
Abstract: The problem of Earth environmental destruction by human activities is becoming dangerous. Engineers responsible for the production of any goods should be well aware of the negative influence of their activities on the state of the planet. This is why the understanding of ecological problems is essential for people responsible for production and industrial design. The energy, which they consume, is increasing the greenhouse effect and the waste poisons the environment. So far, most courses on ecology are offered to specialists in environmental engineering. These courses are filled with many details. The Warsaw Academy of Computer Science, Management and Administration teaches students in the direction of management and production engineering. Upon completion, the students receive the degree of ‘engineer’. Their future work will mainly concern management of different types of industrial enterprises and they will be responsible for organising it in such a way as to avoid a dangerous contribution to environme...
TL;DR: The findings indicate that there is a significant positive relationship between CAD use and knowledge management and concurrent engineering project performance and CAD use for cross-functional information sharing together with the three knowledge management processes — internalisation, combination and externalisation can explain 55.3% of the variance in concurrentengineering project performance.
Abstract: As a complex method for manufacturing and development, concurrent engineering has been studied and implemented extensively in the manufacturing industry to speed up production schedules and to reduce costs. One of the tools used in concurrent engineering is computer-aided design or CAD in short. CAD applications in multifunctional knowledge distribution refer to the use of CAD to provide information to different groups of employees in their organisation to sustain new product development activities. Similarly, the move towards knowledge-based competition amplifies the importance of bridging actions in addition to tactical coalitions where key role of institutional knowledge, system improvement and knowledge sharing are focussed on. However, very few studies have been conducted on the use of CAD and knowledge management in influencing concurrent engineering project performance in Malaysian manufacturing firms. Hence, this study focusses on determining the nature of the relationship between CAD use and knowledge management with concurrent engineering project performance in a Malaysian manufacturing firm. A survey was conducted within the firm, yielding a total of 226 usable responses that were then analysed using SPSS. The findings indicate that there is a significant positive relationship between CAD use and knowledge management and concurrent engineering project performance. In addition, CAD use for cross-functional information sharing together with the three knowledge management processes — internalisation, combination and externalisation can explain 55.3% of the variance in concurrent engineering project performance. An interesting finding of this study based on the multiple regression analysis conducted is that the use of CAD for engineering design and socialisation are not significant in influencing concurrent engineering project performance. In practice, this finding is relevant because when coupled with CAD use, knowledge management approaches that are more externalisation, combination and internalisation-orientated are often practiced if compared to socialisation-orientated activities.
TL;DR: In this article, the authors developed a new approach called advanced overlapping production planning (AOPP) model which considers multi-site process selection, sequential constraints, and capacity constraints in a manufacturing supply chain environment (MSCE).
Abstract: Purpose – The purpose of this paper is to develop a new approach called advanced overlapping production planning (AOPP) model which considers multi‐site process selection, sequential constraints, and capacity constraints in a manufacturing supply chain environment (MSCE). AOPP model may determine the capacity plan and order margin allocation for each site and machines in an MSCE and provide the capacity information for a production planner to effectively adjust the production strategies (e.g. outsourcing, overtime, or adding a work shift) of overloading resources.Design/methodology/approach – First, an AOPP model is presented to model the production scheduling problem in a supply chain with the objective of minimizing the fulfilling cycle time of each order and the overloads of each machine group. Second, a genetic algorithm (GA)‐based approach for solving the AOPP model is developed. Finally, a heuristic adjustment approach is proposed for planners to adjust the production plan whenever there is an excep...
