In this study, a mixed model flow line sequencing problem with two objectives is considered. Mixed model flow line (MML) is known to be a special case of production lines where products are transported on a conveyor belt, and different models of the same product are inter-mixed to be assembled on the same line. We have focused on product-fixed, rate-synchronous lines with variable launching. Ou...

This paper considers a dairy industry problem on integrated planning and scheduling of set yoghurt production. A mixed integer linear programming formulation is introduced to integrate tactical and operational decisions and a heuristic approach is proposed to decompose time buckets of the decisions. The decomposition heuristic improves computational efficiency by solving big bucket planning and...

Mixed Capacitated Arc Routing Problems (MCARP) aim to identify a set of vehicle trips that, starting and ending at a depot node, serve a given number of links, regarding the vehicles capacity, and minimizing a cost function. If both profits and costs on arcs are considered, the Profitable Mixed Capacitated Arc Routing Problem (PMCARP) may be defined. We present compact flow based models for the...
