Evaluation of Manufacturing Process Performance by CONWIP Hybridization of Pull Controlled Production Systems

The main objective of this paper is pioneering an innovative tactic for the synchronization of multi-stage, multi-line, production system. This tactic is mainly depends on the optimization policy, by means of distinct event simulation process for modeling, analysis and distinction of the execution of two alternatives of Kanban control mechanism namely SEKCS (Simultaneous Extended Kanban Control System) and IEKCS (Independent Extended Kanban Control System). At this juncture the authors putting forward the two variants of Extended Kanban control system with the hybridization of CONWIP control policy to incite HSEKCS (Hybrid Simultaneous Extended Kanban Control System) and HIEKCS (Hybrid Independent Extended Kanban Control System) to make use of pooled benefits of a representative production situation in addition to improve the outcome. Therefore in this study the comparison in between different systems of proposed HEKCS specifically are HSEKCS and HIEKCS compared with the Extended Kanban Control Systems variants SEKCS and IEKCS. Simulation studies were conducted for all the five control policies considered and modeled on a multi-line, multi-stage assembly production control system. The relative performance parameters like Throughput or Production rate, Average Waiting Time and Average Work-in-Process, were assessed by means of exponentially varying demands.

Experimental Investigation & Evaluation of Incorporated Material to Set their Optimum Re-Order Point in Kanban Control

In a manufacturing company inventory cost is a significant part of expense. So, the Re-order Point (R.O.P.) of the items must be optimum to reduce its carrying cost. We have study about the inventory and R.O.P. in Nevatia Steel & Alloys Pvt. Ltd. Mumbai and tried to find the optimum R.O.P. by applying VED and XYZ Analysis. Finally, for mathematical modeling we also take help of MatLab.
