Lean and agile manufacturing for work-in-process (WIP) control

Can a shipyard work towards lean shipbuilding or agile manufacturing?

Lean production is regarded by many as simply an enhancement of mass production methods, whereas agility implies breaking out of the mass-production mould and producing much more highly customized products—where the customer wants them in any quantity. In a product line context, it amounts to striving for economies of scope, rather than economies of scale ideally serving ever-smaller niche mark...

Lean Maintenance model to reduce scraps and WIP in manufacturing system:case study in power cables factory

The aim of this paper is to develop an innovative Lean Maintenance model in order to optimize the process flow and reduce or eliminate scraps and work-in-progress (WIP) in a manufacturing context. To achieve these objectives has been formulated a new method, called Lean Root Cause & Defect Analysis (LRCDA), which merges the process steps of the existing Root Cause & Failure Analysis (RCFA) tech...

On the Evolutionary-Fuzzy Control of WIP in Manufacturing Systems

The effectiveness of optimized fuzzy controllers in the production scheduling has been demonstrated in the past through the extensive use of Evolutionary Algorithms (EA) for the Work-In-Process (WIP) reduction. The EA strategy tunes a set of distributed fuzzy control modules whose objective is to control the production rate in a way that satisfies the demand for final products, while reducing W...

Fuzzy work-in-process inventory control of unreliable manufacturing systems

We consider single and multiple part type production lines and networks with ®nite bu€ers and unreliable machines. Three fuzzy control modules, namely, line, assembly, and disassembly controller, are developed. The objective is to keep the work-in-process (WIP) inventory and cycle time at low levels, along with high machine utilization and throughput. This is achieved by adjusting the processin...
