The extended kanban control system for production coordination of assembly manufacturing systems

Abstract

In assembly manufacturing systems there are points in the production process where several component parts are put together in areas called assembly cells so as to form more complex parts called subassemblies. In this paper, we present and compare two variants of the Extended Kanban Control System (EKCS) ± a recently developed pull production control mechanism that combines base stock and kanban control ± for the production coordination of assembly manufacturing systems. In both variants, the production of a new subassembly is authorized only when an assembly kanban is available. Assembly kanbans become available when ®nished subassemblies are consumed. If an assembly kanban is available, in the ®rst variant, each component part of a subassembly is released into the assembly cell as soon as it is available (independent release). In the second variant, however, it is released only when all other component parts also become available (simultaneous release). In both variants, when a component part is released into the assembly cell, it releases its kanban, thus authorizing the production of a new component part.

To Pull or Not to Pull: What Is the Question?

“…More recently, Liberopoulos and Dallery (2002) (building on Chaouiya et al 2000) developed another generalized pull system in the form of a make-to-stock system with separate limits on finished goods (S) and WIP (K) that we will refer to as a (K S) system. This model incorporates classical base stock (K = , S < ), CONWIP K = S , singlestage, reserved-stock kanban as in Buzacott (1989) (K < S), single-stage backordered kanban policy as in Buzacott (1989) and Dallery and Liberopoulos (2002) (K > S), and several other formulations.…”

Lean Construction Techniques and Individual Performance

“…According to Koskela(1992) and Thomas et al(2002), the core concepts of LC is just-in-time (JIT) , which use pull-driven scheduling to reduce the variability in process and waste, units should be available only when required. Three methods are associated with JIT: kanban system, production level, and decrease the number of setup activities (Chaoiya et al 2000;Miltenburg, 2002;Salem et al, 2006). The concept of last planner proposed by Ballard is a technique based on lean think to minimize the waste in a system through assignment-level planning or detailed look-ahead scheduling.…”

The lean manufacturing enterprise: An emerging sociotechnological system integration

“…The kanban system is the realization of backward or pull requests across all processes and suppliers. In fact, the kanban concept has already been extended as a production control system (Chaouiya, Liberopoulos, & Dallery, 2000). Production smoothening comprises standard operations, machine layout, and setup time reduction.…”
