Operations policy for a supply chain system with fixed-interval delivery and linear demand

Operations policy for a supply chain system with fixed-interval delivery and linear demand http://repository.uhamka.ac.id/1624/ This research addresses a production-supply problem for a supply-chain system with fixed-interval delivery. A strategy that determines the optimal batch sizes, cycle times, numbers of orders of raw materials, and production start times is prescribed to minimize the total costs for […]

Machine assignment in a nonlinear multi-product flowline

Machine assignment in a nonlinear multi-product flowline http://repository.uhamka.ac.id/1627/ A group of machines for processing a set of jobs in a manufacturing system is often located in a serial line. An efficient strategy for locating these machines such that the total travel distance or the cost of transporting the jobs is minimized is desired. In this […]

Finite horizon planning with fixed-interval deliveries and no shortage

Finite horizon planning with fixed-interval deliveries and no shortage http://repository.uhamka.ac.id/1629/ The ordering policy of raw materials and the manufacturing batch size for frequent deliveries of finished goods over a finite horizon play a significant role in managing the supply chain logistics economically. This research develops an ordering policy for raw materials and determines an economic […]
