The so-called `Open Compilers' is a technique to incorporate various self-descriptive modules for language customization and optimization based on computational re ection. We apply the open compiler technique to a Java Just-In-Time compiler to develop the OpenJIT compiler, which allows class-speci c customization and optimization, fostering research of new compilation techniques such as applica...

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...

Designing and constructing a technically complex yet efficient, fully integrated fill-finish facility is no small task. The timeframe can be long, the costs can be high, and the stakes with numerous stakeholders involved, can be even higher. But this case study of one biotherapeutic company’s new fill-finish facility in Hillsboro, Oregon, provides practical insights and steps for success for “j...
