CLSC design with simultaneous consideration of product design for manufacturing and remanufacturing

L.J. Zeballos, C.A. Méndez, A.P. Barbosa-Póvoa

Computer Aided Chemical Engineering (Published)
Nov, 2017

This paper studies the network design for a multi-product, multi-echelon and multi-period closed-loop supply chain (CLSC) accounting for decisions on the manufacture of new products and remanufactured versions of the new products. It is important to note that the design for…

Risk measures in a multi-stage stochastic supply chain approach

L.J. Zeballos, C.A. Méndez, A.P. Barbosa-Póvoa

Proceedings of 2015 International Conference on Industrial Engineering and Systems Management, IEEE IESM 2015 (Published)
Jan, 2016

This paper considers the optimal design and planning problem of a closed-loop supply chain (CLSC) where profit maximization is pursued while considering: adjustments in the network structure during the planning horizon providing flexibility to the network as well as uncertainty in supply and customer…

Integrating financial risk measures into the design and planning of closed-loop supply chains

S.R. Cardoso, A.P. Barbosa-Póvoa, S. Relvas

Computers and Chemical Engineering (Published)
Jan, 2016

In this paper, a mixed integer linear programming (MILP) formulation is proposed that integrates financial risk measures into the design and planning of closed-loop supply chains, considering demand uncertainty of final products. The goal is to maximize the supply chain expected net present value…

On the complexity of production planning and scheduling in the pharmaceutical industry: the Delivery Trade-offs Matrix

S. Moniz, A.P. Barbosa-Póvoa, J.P. de Sousa

Computer Aided Chemical Engineering (Published)
Jun, 2015

The manufacturing of pharmaceutical products is preceded by complex development phases where process design, planning, and scheduling problems must be considered as deeply linked, fact that has not yet been adequately handled by the existing literature. In this perspective, this work discusses the…

Resilience metrics in the assessment of complex supply-chains performance operating under demand uncertainty

S.R. Cardoso, A.P. Barbosa-Povóa, S. Relvas, A.Q. Novais

Omega (Published)
