Two-level uncapacitated lot-sizing problem considering the financing cost of working capital requirement

Yuan BIAN, David LEMOINE, Thomas G. YEUNG, Nathalie BOSTEL

Frontiers of Engineering Management 2020, Volume 7, Issue 2,   Pages 248-258 doi: 10.1007/s42524-019-0069-5

Abstract: However, in literatures related to lot-sizing problem, WCR has only been studied in the single-levelIn this paper, we initially adopt WCR model for a multi-level case.A two-level (supplier–customer) model is established on the basis of the classic multi-level lot-sizingTo tackle this problem, we propose sequential and centralized approaches to solve the two-level caseThis property allows us to establish a dynamic programming-based algorithm, which solves the problem

Transient analysis of thermoelastic contact problem of disk brakes

Ali BELHOCINE, Mostefa BOUCHETARA

Frontiers of Mechanical Engineering 2013, Volume 8, Issue 2,   Pages 150-159 doi: 10.1007/s11465-013-0266-6

Abstract:

The main purpose of this study is to analyze the thermomechanical behavior of the dry contact between the brake disk and pads during the braking phase. The simulation strategy is based on computer code ANSYS11. The modeling of transient temperature in the disk is actually used to identify the factor of geometric design of the disk to install the ventilation system in vehicles. The thermal-structural analysis is then used with coupling to determine the deformation established and the Von Mises stresses in the disk, the contact pressure distribution in pads. The results are satisfactory compared to those found in the literature.
