Until now quality assessment of requirements has focused on traditional up-front requirements. Contrasting these traditional requirements are just-in-time (JIT) requirements, which are by definition incomplete, not specific and might be ambiguous when initially specified, indicating a different notion of ‘correctness’. We analyze how the assessment of JIT requirements quality should be performe...

Tracing just-in-time (JIT) compilers record and optimize the instruction sequences they observe at runtime. With some modifications, a tracing JIT can perform well even when the executed program is itself an interpreter, an approach called meta-tracing. The advantage of meta-tracing is that it separates the concern of JIT compilation from language implementation, enabling the same JIT compiler ...

A model for comparing the inventory costs of purchasing under the economic order quantity (EOQ) system and the just-intime (JIT) order purchasing system in existing literature concluded that JIT purchasing was virtually always the preferable inventory ordering system especially at high level of annual demand. By expanding the classical EOQ model, this paper shows that it is possible for the EOQ...

JIT compilation is a model of execution which translates at run time critical parts of the program to a low level representation. Typically a JIT compiler produces machine code from an intermediate bytecode representation. This paper considers a hardware JIT compiler targeting FPGAs, which are digital circuits configurable as needed to implement application specific circuits. Recent FPGAs in th...

I explore the role of the Just-in-Time (JIT) inventory system in the increase of cash holdings among U.S. manufacturing firms. I first demonstrate the empirical importance of JIT in shaping cash policy. I then develop a model to analyze the mechanism through which JIT affects cash and quantify its impact. In the model, both cash and inventory can serve as working capital. As firms switch from t...

The purpose of this paper is to aid just-in-time (JIT) manufacturers in selecting the most appropriate suppliers and in evaluating supplier performance. Many manufacturers employ the JIT philosophy in order to be more competitive in today’s global market. The success of JIT on the production floor has led many firms to expand the JIT philosophy to the entire supply chain. The procurement of par...

Recently Just-In-Time (JIT) production has attracted increasing interest throughout the Chinese manufacturing industries and its programs have been widely implemented. Currently, there are few studies conducted about JIT manufacturing implemented by small manufacturing firms in China, even though small firms are still dominant in many areas of manufacturing industries in China. This study analy...

Just-In-Time (JIT) compiler is an e cient and preferred style of implementing the Java Virtual Machine (JVM) on resource-rich machines. Using a JIT compiler, the bytecodes are translated to native code at runtime. In this paper, we investigate where the time is spent in such dynamic compilers and how well a smart JIT compiler can do. Next, we propose architectural mechanisms that can be used to...

JIT spraying allows an attacker to subvert a JustIn-Time compiler, introducing instruction sequences useful to the attacker into executable regions of the victim program’s address space as a side effect of compiling seemingly innocuous code in a safe language like JavaScript. We present new JIT spraying attacks against Google’s V8 and Mozilla’s SpiderMonkey JavaScript engines on ARM. The V8 att...
