Concurrent Engineering and based Applications for 3D Big Data

European companies’ competitiveness depends on obtaining innovative products. In the last years, clients demand started to be higher and more complex. Because of that, managing products development processes have become a necessity. Product development processes need to be proficient and flexible: less complex and more competence-focused. 3DSpace brings more solutions in this matter. EXALEAD transforms large volumes of heterogeneous, multi-source data into real-time information intelligence to help users improve business processes and gain competitive advantage. EXALEAD enables organizations to gather and enrich Big Data to deliver that information in the process of integrated product development and allows customers to fully manage product programs, from 3D design to traceability of changes, cost, quality and issue analytics. Concurrent or Simultaneous Engineering is one of the fundamental approaches that meet the challenges mentioned above. EXALEAD uses CloudView to process big data flows. Concurrent Engineering represents a standardized approach to integrated product improvement which accentuates and gives priority to the customer expectations level. In this matter, 3DSpace’s ENOVIA is used together with graphic software for manufacturing. It is about teamwork and confidence in which the decision-making process is consensual, even from the beginning of the product life cycle.

Set-Based Concurrent Engineering Process Model and Systematic Application on an Electronic Card Reader

Set-based concurrent engineering (SBCE), also known as set-based design, is a state-of-the-art approach to the new product development process. SBCE, simply, provides an environment where designers explore a wide range of alternative solutions in the early stages of product development. After gaining knowledge, solutions are narrowed down until the optimal solution is ensured. Such an environment saves considerable amount of cost and time while reaching innovation and high quality in the products. However, industrial practitioners seek a clear and systematic application throughout an SBCE process. This paper demonstrates a well-structured SBCE process model and its step-by-step application on a product called “electronic card reader”. Real data is used in the industrial case study. Results showed the benefits of applying SBCE in both the product, and the process of new product development.

Lean 6S in Food Production: HACCP as a Benchmark for the Sixth S “Safety”

This article presents the integration of lean 6S methodologies and hazard analysis and critical control points (HACCP) in the food production sector. Through the study, it is seen that non-food industrial production is not very different from that of food, and in many cases, it assimilates protocols and ideas that are already working in the food industry. Such is the case of risk analysis, critical control points or hygiene, which are part of the food production protocol and of the industry in general. After the integrative analysis, the article proposes a common lean 6S–HACCP model, which can be used both in food production and in non-food industrial production. Food quality management systems, a fundamental element of HACCP which the project must necessarily include, is analyzed in-depth. The peculiarities prior to the integration of the mandatory HACCP and the voluntary lean are analyzed, as well. Throughout the manuscript, an important series of considerations regarding lean is collected, giving practical examples of its use in the food environment. The study makes special reference to concurrent engineering, which, as is known, constitutes the link between 5S and lean. This analysis aims to present a lean 6S HACCP implementation project.

The role of concurrent engineering in resilient critical infrastructures during disasters

The world has complex mega-cities and interdependent infrastructures. This complication in infrastructure relations makes it sensitive to disasters and failures. Cascading failure causes blackouts for the whole system of infrastructures during disasters and the lack of performance of the emergency management stakeholders is clear during a disaster due to the complexity of the system. This research aimed to develop a new concurrent engineering model following the total recovery effort. The objectives of this research were to identify the clustered intervention utilized in the field of resilience and developing a cross-functional intervention network to enhance the resilience of societies during a disaster. Content analysis was employed to classify and categorize the intervention in the main divisions and sub-divisions and the grouping of stakeholders. The transposing system was employed to develop an integrated model. The result of this research showed that the operations division achieved the highest weight of information interchange during the response to improve the resilience of the system. The committee of logistics and the committee of rescue and relief needed the widest bandwidth of information flow in the concurrent engineering (CE) model. The contributed CE model helped the stakeholders provide a resilient response system. The final model and the relative share value of exchanging information for each workgroup can speed up recovery actions. This research found that concurrent engineering (CE) is a viable concept to be implemented as a strategy for emergency management. The result of this research can help policymakers achieve a collaborative teamwork environment and to improve resilience factors during emergency circumstances for critical infrastructures.

Physics-based trade-off curves to develop a control access product in set-based concurrent engineering environment

Purpose This paper aims to present a process to generate physics-based trade-off curves (ToCs) to facilitate lean product development processes by enabling two key activities of set-based concurrent engineering (SBCE) process model that are comparing alternative design solutions and narrowing down the design set. The developed process of generating physics-based ToCs has been demonstrated via an industrial case study which is a research project. Design/methodology/approach The adapted research approach for this paper consists of three phases: a review of the related literature, developing the process of generating physics-based ToCs in the concept of lean product development, implementing the developed process in an industrial case study for validation through the SBCE process model. Findings Findings of this application showed that physics-based ToC is an effective tool to enable SBCE activities, as well as to save time and provide the required knowledge environment for the designers to support their decision-making. Practical implications Authors expect that this paper will guide companies, which are implementing SBCE processes throughout their lean product development journey. Physics-based ToCs will facilitate accurate decision-making in comparing and narrowing down the design-set through the provision of the right knowledge environment. Originality/value SBCE is a useful approach to develop a new product. It is essential to provide the right knowledge environment in a quick and visual manner which has been addressed by demonstrating physics knowledge in ToCs. Therefore, a systematic process has been developed and presented in this paper. The research found that physics-based ToCs could help to identify different physics characteristics of the product in the form of design parameters and visualise in a single graph for all stakeholders to understand without a need for an extensive engineering background and for designers to make a decision faster.

An applied methodology for tolerance design based on concurrent engineering

Tolerance design is an important part of the product development and manufacturing process. Studies show that using a reliable and efficient tolerance design method can effectively improve product quality and reduce manufacturing costs. Although numerous studies have been carried out in the area of tolerance analysis, combining the tolerance analysis with the concurrent engineering theory has been rarely studied so far. In order to resolve this shortcoming, a comprehensive tolerance design methodology based on concurrent engineering was proposed in the present study to shorten the product development cycle, improve product quality, and reduce manufacturing costs. To this end, experts from different engineering fields were employed to form a concurrent engineering team that works together. The tolerance design activities were divided into seven stages, including design requirements definition, dimension chain identification, initial geometric dimensioning and tolerancing, variation analysis, release technical specification, validation, and continuous improvement. Then the detailed work process of each stage is presented. Based on the Monte Carlo theory and 3D computer-aided tolerance software, a variation analysis framework was proposed. Finally, the gap between taillight and bodyside was considered a test case, and a specific operation method of tolerance design using this framework is expounded. In the studied cases, the calculated and measured mean value of the gap was 1.5 and 1.5368 mm, respectively, indicating the simulation error of 2.5 %. The obtained results show that the gap tolerance by the proposed method is consistent with the tolerance fluctuation in actual production.

Agile methodologies applied to Integrated Concurrent Engineering for spacecraft design

In recent years, space projects have evolved to faster and more variable projects. To adjust the design processes in accordance, new work methodologies arise, as the Concurrent Engineering (CE). This working discipline is characterized by collaborative design and the flux of information being improved by working in a dedicated environment. CE has been recently adopted by space industry for the preliminary design phase of spacecrafts and other space systems. However, this methodology does not envisage tasks prioritization, which is a fundamental aspect to achieve an optimal design solution with an efficient allocation of resources. In this work a variation of CE discipline by applying Agile methodologies (in which the aspect of task prioritization is essential), is proposed. Agile methodologies allow the proper distribution of the design effort depending on the project priorities, the state of the design and the requirements, in a continuous process to improve the design solution. The general aspects of the proposed method are presented and applied to the design of a space mission, the results being analysed and compared with to the classical CE process in order to outline its differences and similarities with CE and Agile methodologies and show its potential for a new environment for space project design.
