Modern Java Compilers, such as Sun’s HotSpot compilers, implement a number of optimizations, ranging from high-level program transformations to low-level architecure dependent operations such as instruction scheduling. In a Just-in-Time (JIT) environment, the impact of each optimization must be weighed against its cost in terms of total runtime. Towards better understanding the usefulness of in...

This paper presents a mathematical model, based on the just-in-time (JIT) idea, for solving machine con ̄icts in steelmaking-continuous casting (SCC) production scheduling in the computer integrated manufacturing system (CIMS) environment. The model is developed as a non-linear model based on actual production situations, considering both punctual delivery and production operation continuity. It...

Flow shop scheduling problem has a wide application in the manufacturing and has attracted much attention in academic fields. From other point, on time delivery of products and services is a major necessity of companies’ todays; early and tardy delivery times will result additional cost such as holding or penalty costs.  In this paper, just-in-time (JIT) flow shop scheduling problem with preemp...

Managers seeking to improve lead-time performance are challenged by how to balance resources and investments between process improvement achieved through lean/justin-time (JIT) practices and information technology (IT) deployment. However, extant literature provides little guidance on this question. Motivated by both practical importance and lack of academic research, this article examines empi...

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 ...

The feasibility and efficacy of virtual reality job interview training (VR-JIT) was assessed in a single-blinded randomized controlled trial. Adults with autism spectrum disorder were randomized to VR-JIT (n = 16) or treatment-as-usual (TAU) (n = 10) groups. VR-JIT consisted of simulated job interviews with a virtual character and didactic training. Participants attended 90 % of laboratory-base...

Just‐In‐Time (JIT) production has received a great deal of attention, worldwide, since its introduction in Japan a few decades ago. It has been well documented that some of the main benefits of JIT implementation are reduction of inventories, lead‐time reduction, and cost savings. Most of the previous research on the impact of JIT on firm performance has either been anecdotal (one‐firm studies)...

Interpreted languages are widely used due to ease to use, portability, and safety. On the other hand, interpretation imposes a significance overhead. Just-inTime (JIT) compilation is a popular approach to improving the runtime performance of languages such as Java. We compare the performance of a JIT compiler with a traditional compiler and with an emulator. We show that the compilation overhea...

Tracing JIT compilation generates units of compilation that are easy to analyse and are known to execute frequently. The AJITPar project investigates whether the information in JIT traces can be used to dynamically transform programs for a specific parallel architecture. Hence a lightweight cost model is required for JIT traces. This paper presents the design and implementation of a system for ...
