Coordinating Production And Recycling Decisions With Stochastic Demand And Return, Jianmai Shi, Guoqing Zhang, Jichang Sha, Saman Hassanzadeh Amin

Mechanical, Automotive & Materials Engineering Publications

In this paper, the joint production and recycling problem is investigated for a hybrid manufacturing and remanufacturing system where brand-new products are produced in the manufacturing plant and recycled products are remanufactured into as-new products in the remanufacturing facility. Both the brand-new products and remanufactured products are used to satisfy customer demands. Returns of used products that are recycled from customers are assumed to be stochastic and nonlinearly price-dependent. A mathematical model is proposed to maximize the overall profit of the system through simultaneously optimizing the production and recycling decisions, subject to two capacity constraints — the manufacturing capacity and …

Analysis, Modeling And Imporvement Of Stamped Parts Quality Using Generalized Linear Models, Foad Hassanmirzaei, Zbigniew Pasek

Industrial and Manufacturing Systems Engineering Publications

This paper presents an approach used for improving the visual quality of body panels produced in an automated press shop of a car manufacturer. To solve the complexproblem of panels’ visual defects,the optimal values of process parameters based on Generalized Linear Models (GLZ) were identified and deployed. The project focused on parts exhibiting excessive rejection rates. To deal effectively with the case in which the distribution function representing the number of defects in the panels was found to be binomial with presence of some covariates in the model, the research approach focused on development of Log it Models.
