Abstract: The purpose of this communication is to give an overview and an analysis of the research about 'production systems design' and in particular production lines. The production system design is complex since it involves several difficult and hard subproblems. These issues might include: the equipment selection; the sizing and allocation of buffer; the workstations workload balancing; the selection and dimensioning of transport resources and also the workshop layout.
This presentation aims to give an overview of some recent and well known results on some issues above. A particular focus will be made on analytical models and resolution algorithms to firstly assess the performance and then to optimize the design of production lines.
Quite clearly, the execution of a task requires material resources and human skills and respect of technological and organizational conditions and precedence constraints, for instance. The various problems, cited above, are generally common to any approach to the optimization of the design of a production system. However, there are several types of production lines. According to Boysen et al., a classification of the different production lines is possible as: the model type (single, joint, multiple), the goods transfer mode between stations (synchronous, asynchronous, and continuous), line processing (manual or automated) and finally design or re-design (first installation or reconfiguration). The presentation will focus on the:
- Models and techniques of analytical simulation modeling of production lines with work on aggregation methods and simulation:
- - The EMM (Equivalent Machines methods) method, which is to propose a new analytical approach to the assessment of the performance of a production line in series. This line is composed of unreliable machines separated by intermediate stocks to finite capacity.
- - Line system representation by simulation techniques
- Optimization of the spaces of storages
- Optimization of robotic lines
- Multi-objective methods for the design of lines
