Manajemen dapat mempengaruhi tinggi rendahnya laba perusahaan karena megontrol kegiatan in dan out dana yang mengalir atas aktivitas apapun. Pentingnya pengendalian pengadaan memberikan efek besar terhadap jalannya proses produksi tidak akan berjalan bila tanpa adanya persediaan bahan baku memadai, tetapi disisi lain kelebihan juga dampak buruk bagi mengakibatkan pemborosan biaya pengadaan. Pen...

In today's highly competitive business environment, companies strive to satisfy customers by delivering high-quality products and services. This holds true for a cargo inspection services company, which relies on procuring raw materials equipment ensure optimal service delivery. One crucial aspect of efficient operations is monitoring controlling the inventory cans used sampling. Effective cont...

In this paper we address a hybrid flow shop scheduling problem considering the minimization of the sum of the total earliness and tardiness penalties. This problem is proven to be NP-hard, and consequently the development of heuristic and meta-heuristic approaches to solve it is well justified. So, we propose an ant colony optimization method to deal with this problem. Our proposed method has s...

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...
