The design of façades insulating-envelopes based on rectangular configurable panels is addressed via guillotine cuts. This design is treated as a two-dimensional orthogonal packing problem which considers the specific geometry and structure of each facade. Among the various packing algorithms dedicated to this particular design problem, the cutting approach is the most appropriated to design aesthetic...
This paper proposes first integrated models dealing with the management of the coupling between system design environment and project planning one. A benchmark done with fifteen companies belonging to the world competitiveness cluster Aerospace Valley has highlighted a lack of models, processes and tools for aiding the interactions between the two environments. An integrated model taking into account...
We present the coupling of two constraint-based environments into an on-line support system for facade-layout configuration in the context of building renovation. The configuration consists on the definition and allocation of a set of rectangular parameterization panels over a facade surface. The coupling allows solving two configuration tasks: To configure a set of questions relating the renovation...
In order to reduce energetic consumption, buildings may be retrofitted by covering them with an insulation envelope composed of rectangular parameterizable panels. In such scenario different envelopes configurations are possible to cover the same building. Thus, a crucial aspect of the retrofit is to select, among potential solutions, those ones providing good thermal performance at reasonable cost...
This paper looks at the possibility of configuring high performance renovation of apartment buildings by the use of a constraint satisfaction problem (CSP). A new thermal envelope wraps the whole building and allows it to achieve a really low energy performance of 25 kWh/m2/year. This new thermal envelope is composed of rectangular panels, always comprising insulation and cladding, and sometimes including,...
This communication deals with mass customization and the association of the product configuration task with the planning of its production process while trying to optimize cost and cycle time. In some previous works, we have proposed an optimization algorithm, called CFB-EA. This communication concerns a way to improve CFB-EA for large problems. Previous experiments have highlighted that CFB-EA is...
The problematic addressed in this article is dealing with the improvement of retrieval in Case-Based Reasoning for system design. The retrieval activity is based on the evaluation of similarities between requirements (target) and the solutions (sources). However, similarities between features is often a subjective kind of knowledge difficult to formalize within companies. Based on an ontology of domain,...
Facilitating product customization, configuration has attracted much attention from both academia and industry alike. However, the available studies and the reported systems focus on sales or product configuration while leaving other important issues in developing customized products unaddressed. In this study, we propose a new configuration concept: integrated SAles, Product and Production configuration...
This article proposes a model dealing with the synchronisation of system design process and project planning process. This synchronisation is named synchronous coupling and is based on the assumption which states that a mapping exists between system Bill Of Materials and projects Work Breakdown Structure. Synchronous coupling ensures a consistency in the monitoring and the control of the system design...
This communication aims to associate the product configuration task with the planning of its production process in order to make consistent decisions while trying to minimize cost and cycle time. A two step approach is described with relevant aiding tools. During the first one, configuration and planning are considered as two constraint satisfaction problems and are interactively assisted by constraint...
This communication deals with the possibility of coupling together interactive product configuration tools with process planning tools in order to communicate and make consistent decisions made from one side to the other side. The first section introduces the problem and the general ideas of the proposed solution. Then, two constraints based models, respectively relevant to product configuration and...
