An approach to solve the facility layout problem based on the worst-case scenario

A New Trend in Designing Plant Layouts for the Process Industry

“…Solving the layout with the deterministic approach tends to produce more conservative layouts (Diaz-Ovalle et al, 2008). However, when the toxic material is too toxic this approach may produce layouts occupying a large area.…”

“…Since the wind in calm can occur at any direction, then the risk becomes symmetric and contours having the same risk level have circular shape. A deterministic model based on the worst scenario is given in (Diaz-Ovalle et al, 2008). A threshold limit value (TLV) can be used to avoid exposures that may produce adverse effects to pupil.…”

Assessment of domino effect: State of the art and research Needs

“…Therefore, adequate measures implemented in the design phase may result in safer plants from the point of view of escalation. Design optimization tools mainly focus on economic aspects, even if safety issues have been considered in some recent works (Díaz-Ovalle et al, 2010;Jung et al, 2010;Jung et al, 2011;Nolan and Bradley, 1987;Penteado and Ciric, 1996;Patsiatzis et al, 2004). Several tools can be applied in order to anticipate safety issues related to the prevention of escalation in layout design.…”

A grid-based facilities allocation approach with safety and optimal heat exchanger networks synthesis

“…Dealing with these effects can be carried out using a stochastic approach as suggested in Vázquez-Román et al (2010), or a deterministic approach based on the worst-case scenario (Díaz-Ovalle et al, 2010). While the stochastic approach indicates different risk profiles, the deterministic approach predicts symmetric profiles which are easier to model.…”
