ÐThe Java Virtual Machine (JVM) is the cornerstone of Java technology and its efficiency in executing the portable Java bytecodes is crucial for the success of this technology. Interpretation, Just-In-Time (JIT) compilation, and hardware realization are wellknown solutions for a JVM and previous research has proposed optimizations for each of these techniques. However, each technique has its pr...

OpenJIT is an open-ended, reflective JIT compiler framework for Java being researched and developed in a joint project by Tokyo Inst. Tech. and Fujitsu Ltd. Although in general self-descriptive systems have been studied in various contexts such as reflection and interpreter/compiler bootstrapping, OpenJIT is a first system we know to date that offers a stable, full-fledged Java JIT compiler tha...

This paper implements the inventory model developed in the first part of this paper in a simplified problem to simultaneously reduce costs and risks in JIT systems. This model is developed to ascertain an optimal ordering strategy for procuring raw materials by using regular multi-external and local backup suppliers to reduce the total cost of the products, and at the same time to reduce the ri...

Given the increased competitive pressures on manufacturing, many companies are interested in implementing Just-In-Time (JIT) manufacturing philosophies. At the shop floor level, one application of JIT is the introduction of kanbans in order to control in-process inventory. Traditionally, it has been argued that kanban systems work well when the shop floor environment is fairly stable. In this p...

Manta is a highly optimizing compiler that translates Java source code to binary executables. In this paper, we discuss four Java-specific code optimizations and their impact on application performance. We assess the execution time of three application kernels, comparing Manta with the IBM JIT 1.3.0, and with C-versions of the codes, compiled with GCC. With all three kernels, Manta generates fa...

Estimation of the optimal size order is one key tasks in determining parameters urban freight restocking system. The existing analytical models and methods are considering each technology separately they do not compare Economic Order Quantity (EOQ) Just-in-tme (JIT) technologies. purpose this research was to evaluate efficiency JIT EOQ would help selecting delivery model, analyzing functioning ...

One of the important elements that have been playing a significant role in today’s global business operations is culture. An important dimension of cultural analysis has been added to its discussion of transferability of JIT/TQM to other countries ever since the Japanese management techniques, JIT and TQM, became popular throughout the world. This paper reviews the transferability of these popu...

In today’s competitive global markets, Just-in-Time (JIT) is one of the main lean manufacturing approaches. It is used in organizations to improve performance and reduce costs and as a strategic core capability to ensure their market position. However, using JIT tightly couples various functions of the Supply Chain and increases the risk of propagating disruptions through the entire system. Thi...
