A Scheduling based Backlog Reduction Method in CONWIP Production Systems

Evaluation of multi-product lean manufacturing systems with setup and erratic demand

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 Production Authorisation Cards (PAC). A lar...

Making a High-Mix Make-to-Order Production

A high-mix, make-to-order production system can become inefficient when non-value added operations consume too much time, space or labour. To address these issues, cell re-layout is conducted and a CONWIP system is proposed. The cell re-layout started with data collection on current layout, product mix and routings, then the current layout was modified to develop several alternatives, and final...

Simultaneous production planning and scheduling in a hybrid flow shop with time periods and work shifts

Simultaneous production planning and scheduling has been identified as one of the most important factors that affect the efficient implementation of planning and scheduling operations for the production systems. In this paper, simultaneous production planning and scheduling is applied in a hybrid flow shop environment, which has numerous applications in real industrial settings. In this problem...

Controlling shop ̄oor operations in a multi-family, multi-cell manufacturing environment through constant work-in-process

This paper discusses pertinent issues in applying CONstant Work-In-Process (CONWIP) principles to control shop ̄oor operations in a manufacturing environment characterized by several product families processed along di€erent routes in several production cells. The approach we take is to simultaneously answer two major questions: (1) what is the best WIP level? and (2) how to arrange the backlog ...
