The crucial step in the design of a Cellular Manufacturing (CM) system is the Cell Formation (CF) problem. This problem consists of identifying the part families and the machine groups and, consequently, forming manufacturing cells. The aim of this paper is to formulate a new multivariate approach based on a correlation analysis for solving CF problem. The(More)
Digital Factory (DF) can be defined as a set of software tools and methodologies allowing the design, simulation, initiation and optimization of production systems, with regards to the Product Development Process (PDP). However, it remains not widespread in the industries, essentially due to the insufficient capability to communicate between the different(More)
Cellular manufacturing (CM) is an important application of group technology (GT) that can be used to enhance both flexibility and efficiency in today’s small-to-medium lot production environment. The crucial step in the design of a CM system is the cell formation (CF) problem that involves grouping parts into families and machines into cells. The CF problem(More)
In this paper, the authors present a hybrid genetic approach for the two-dimensional rectangular guillotine oriented cutting-stock problem. In this method, the genetic algorithm is used to select a set of cutting patterns while the linear programming model permits one to create the lengths to produce with each cutting pattern to fulfil the customer orders(More)
Digital Factory (DF) aims at proposing simulation tools to design a product and its production system in parallel. Nevertheless, DF is marked by the multiplicity and heterogeneity of simulation models that are used, that slows down its usage in industry. We propose in this paper a conceptual model to manage the different simulation information created and(More)
Optimization of integrated mechatronic design is a complex process characterized by an important number of requirements, design variables, constraints and objectives. Therefore, it is very important to efficiently decompose the system design problem into a set of quasi-separable sub-problems to reduce the design complexity and minimize the computational(More)
Cell Formation (CF) problem involves grouping the parts into part families and machines into manufacturing cells, so that parts with similar processing requirements are manufactured within the same cell. Many researches have suggested methods for CF. Few of these methods; have addressed the possible existence of exceptional elements (EE) in the solution and(More)
Cellular Manufacturing is one such strategy, which has emerge as an important technique to cope up with fast changing industrial demands and for the application of newer manufacturing systems. This research work has been carried out as a case study in an automotive parts manufacturing company with the objective of designing the cells, evaluating it and(More)
