A comparative study of cell formation techniques: experimental findings on data-dependency and solution quality
Article Abstract:
A comparative study of cell formation techniques is conducted. Four problems areas related to comparative studies are identified. These are asymmetry among methodologies in relation to input data, sensitivity to input data, ability of cell formation methodologies to produce different solutions, and criteria for acceptable cell performance. It is demonstrated that choices within the four aforementioned areas can be dealt with within the context of a comparative study. The study reveals basic relations between cell formation techniques, the type of input data used, the characteristics of the data, and the resulting performance.

Analysis of local decision rules in a dual-kanban flow shop
Article Abstract:
An extension of Berkley and Kiran's 1991 study on the effects of four kanban policies, which include number of kanbans and status of waiting withdrawal kanbans, showed the impact of those policies in four performance criteria such as average customer wait-time and total inventory. The result is a good tool for managers in evaluating system performance in an improvement process where these kanban variables are present. The data regarding withdrawal kanbans in sequencing decisions leads to the simultaneous improvement in customer wait time and total inventory.

Simulation tests of FCFS and SPT sequencing in kanban systems
Article Abstract:
The performance of first come first serve (FCFS) and shortest processing time (SPT) in single-card kanban systems with varying queue capacities and material-handling frequencies is evaluated. Results show that on single-card kanban-controlled lines FCFS has greater average production rates than SPT, and SPT performs better with small queues and frequent material handling. Lastly, in two-card systems with periodic material handling, material-handling mechanism may affect results.
