Analysis Of A Just-In-Time Production System With Supplier Kanbans, Surendra Gupta, Kenichi Nakashima
Analysis Of A Just-In-Time Production System With Supplier Kanbans, Surendra Gupta, Kenichi Nakashima
Surendra M. Gupta
In this paper, we introduce a generalized stochastic Petri net (GSPN) to model a single-process, single-product, Just- In-Time (JIT) manufacturing facility with a supplier kanban system for multiple vendors. Its properties are investigated and the effects of the vendors' activities on the system are discussed using ANOVA.

Uncertainty And Back-Ordering In Multi-Level Product Structures, Surendra Gupta, Louis Brennan
Surendra M. Gupta
The influence of uncertainty on the performance of Material Requirements Planning (MRP) systems has been the focus of several studies. All of these studies have incorporated non back-order lot sizing rules. However, attention has been recently directed to back-order lot sizing rules. This paper considers the impact of the presence of both supply and demand uncertainties on the performance of MRP systems in an environment where back-orders are planned. The word reported here is based on a simulation study involving a variety of supply and demand conditions. The study establishes the significance of product structure shape and variant, lot sizing …
