In modern industry, the development of complex products involves engineering changes that frequently require redesigning or altering the products or their components. In an engineering change process, engineering change requests (ECRs) are documents (forms) with parts written in natural language describing a suggested enhancement or a problem with a product or a component. ECRs initiate the change process and promote discussions within an organization to help to determine the impact of a change and the best possible solution. Although ECRs can contain important details, that is, recurring problems or examples of good practice repeated across a number of projects, they are often stored but not consulted, missing important opportunities to learn from previous projects. This paper explores the use of Self-Organizing Map (SOM) to the problem of unsupervised clustering of ECR texts. A case study is presented in which ECRs collected during the engineering change process of a railways industry are analyzed. The results show that SOM text clustering has a good potential to improve overall knowledge reuse and exploitation.

The Impact

This paper analyzes the impact of 3D model annotations on CAD user productivity in the context of the New Product Development Process. These annotations can provide valuable information to support an improved design intent communication. Comparably, they can play the same role as source code comments to support code maintainability in software engineering. A 3D CAD model is a geometry representation and it also stores the modeling strategy used to build it. Alteration of a complex CAD model usually represents a time consuming task due to the lack of an explicit explanation of the design rationale followed to build that 3D model. An experimental study conducted with Spanish and Mexican CAD students indicates that it is possible to reduce the time needed to perform engineering changes in existing models by between 13–26% by using annotations. Also some factors that affect the impact of annotations on the engineering change process such as part and alteration complexity were identified.

Resilience Assessment

The paper evaluates an application of the resilience measuring tool Resilience Assessment Grid (RAG) in the aircraft components production. For the purpose of the evaluation a specific RAG model for a change process is created. The paper contains a description of change process and the approval process of the engineering change proposal. Paper describes BPMN and FRAM models created to support model RAG and which both clarify relations among the functions inside the management of change process. The paper presents a possible approach for the Resilience Assessment Grid model creation. The outcome is a creation of a change process profile in a company producing aircraft components in which change process and approval of the engineering proposed change is managed, and a recording of a current state of four  process potentials that can be used by the company management to develop wider safety awareness among employees.

The authors of the article carried out the analysis of the teaching need for the subject of engineering change at Vilnius Gediminas Technical University. The conducted investigation was based on evaluating the situation of the engineering change process and on innovative knowledge in the field. The examination of literature sources and the results of expert evaluation pointed out a number of activities to support the engineering change process. The activities must be provided with relevant innovative knowledge. Recent engineering changes are related to product and process innovations when the new functions and purposes of product development can be, in many cases, achieved through designing mechatronic systems and introducing new materials to improve the product. Engineering change management is important for designing and producing products. For this reason, the modules of study programmes in this particular field give more knowledge and abilities for the students.
