This paper presents a simulation study on production and inventory control at the supply chain (SC) level and examines through a series of experiments the potential impact of the Hybrid Kanban-CONWIP production control strategy on the trade-off between the conflicting objectives of maximising customer service level and minimising Work-In-Process (WIP).(More)
Lean Manufacturing often simply referred to as Lean is a process management philosophy that aims to improve the way in which products are manufactured. It does this through identifying and removing waste and creating a smooth transition between stages in the production process. To a large extent, it relies on visual and simple mechanical aids to assist in(More)
This paper presents a new batch scheduling heuristic - the Time-Limited Next Arrival heuristic for batch processing and setup reduction (TLNA). This heuristic has been defined for a batch processing machine group in a re-entrant manufacturing environment where setups are sequence-dependent. When making the scheduling decision, TLNA takes into account future(More)
The consideration of demand variability in Multi-Product Lean Manufacturing Environment (MPLME) is an innovation in production system engineering. Manufacturing systems that fail to recognise demand variability generate high Work-In-Process (WIP) and low throughput in MPLME. In response to demand variability, organisations allocate large quantities of(More)
Managing demand variability is a challenging task in manufacturing environments. Organizations that implemented Kanban-Like Production Control Strategies (PCS) especially in a multi-product manufacturing environment (MPME) plan a large volume of production authorization cards (PAC) to respond to demand variability. The issue associated with high PAC for(More)
When inspection economies are implemented in multi-product, multi-stage, parallel processing manufacturing systems, there exists a significant risk of losing control of the monitoring efficacy of the sampling strategy adopted. For a product-based sampling decision limited to a particular station in a production segment, the randomness of the departure(More)
