Just-in-time (JIT) has been a popular operation strategy partly because of its success in the japanese automobile industry. Various benefits such as inventory reduction, improved operations efficiency, and faster response, have been studied widely in previous studies. Therefore, successful implementation of JIT is vital to many companies. This research makes use of a case study to explore five ...

This paper presents a model for an unreliable production line, which is operated according to demand with constant work-in-process (CONWIP). A simulation model is developed based on the discrete model and several case problems are analyzed using the model. The model is utilized to optimize storage space capacities at intermediate stages and the number of kanbans at the last stage, which is used...

The project aimed to create a circuit simulator that produces JIT compiled native code through LLVM’s APIs. A JIT based simulation approach provides native simulation speed, while still allowing native code to be recompiled to provide circuit debugging features unavailable in statically compiled simulators. The result of the project is a simulator that performs competitively against existing si...

This research studies the single-stage supply chain system operated under JIT technique. A kanban mechanism is employed to assist in linking the production processes in a supply chain system. The number of kanbans, batch size, and the number of batches are determined optimally. Based on this information, kanban operation between two adjacent plants can be worked out for controlling the supply c...

A practical method of JIT modelling for a blast furnace process data whose characteristics are very complicated physical phenomena and stiff nonlinear process are studied. The proposed method is composed of severely selecting process data variables by stepwise method and searching the past similar data in quantized topological space constructed by the selected variables. The effectiveness of th...

A combined MRP(material requirement planning) and JIT(just in time) system can be more effective manufacturing system which utilizes the best attributes of each manufacturing system need to accommodate the best planning features of MRP and the best execution features of JIT to address the changing needs of industry. When MRP and JIT involve in any production system than its balance the all enti...

Purpose – The purpose of this paper is to explore if six sigma and lean are new methods, or if they are repackaged versions of previously popular methods – total quality management (TQM) and just-in-time (JIT). Design/methodology/approach – The study is based on a critical comparison of lean with JIT and six sigma with TQM, a study of the measure of the publication frequency – the number of aca...

Dynamic superinstructions and replication can provide large speedups over plain interpretation. In a JVM implementation we have to overcome two problems to realize the full potential of these optimizations: the conflict between superinstructions and the quickening optimization; and the non-relocatability of JVM instructions that can throw exceptions. In this paper, we present solutions for thes...

A medium sized UK based academic publishers own a subsidiary printing business. Presently the Academic Printers (AP) is experiencing productions line flow problems reducing the efficiency of the operation. Most of the problems are generated by the imbalanced workflow through the system. By implementing a JIT production planning system it is hoped that some of the production problems can be reso...

For reasons well known, change has always been uncomfortable to business systems. There is some resistance and resentment whenever changes are made in the existing set-up more so in the case of technological change. New technologies have often brought structural changes to the business systems, which affect their cultural complexion as well. In recent years, there has been a stream of new innov...
