Design Flowchart for Operational System Safety

Introduction

In the life cycle of any process, a design phase is essential. That said, as in the case of production systems, the design study, or feasibility study of the latter, has taken on greater importance in intelligent industry. There are two aspects to it: the first is the material part of the company that produces goods, it’s all about products and materials; the second is the system as a whole; the hardware system, human resources and organizational structure.

With the multitude of design methods to be found in the literature (Hampson, 2015; Choulier, n.d.; Herrou & Elghorba, 2005; Beauvallet & Houy, 2009), the choice of one among them is more difficult than it appears. The aim of this section is to propose a design aid method which will give priority to operational safety in the production process, and in particular to the security of goods and people in the production system to be designed.

The aim of this study is to find a model that we would like to develop further, by introducing algorithms with iterations that will enable us to continuously improve the system under study.

In the first part of this chapter, we attempt to define design according to the literature, focusing on maintenance and innovation. This is followed by a non-exhaustive presentation of design support methods, with a comparative table of the methods presented.

The second part is devoted to defining safety and security by reference. We then refer to the model proposed by Robin (Cressent et al., 2009) called MéDISIS; a method for integrating safety analysis into systems engineering; (in French: Méthode D’Intégration des analyses de Sdf à l’Ingénierie Système) based on the SysML method. Then we presented the tools used for the design model presented by Nabdi and Herrou (2017). The result of this analysis was to propose a model integrating the two previous approaches, in an attempt to improve the design of production systems. Finally, we have outlined the problems that our model may encounter, and the prospects for this work.
