This paper addresses the combined JIT scheduling and tool replacement problem on a machining centre. The objective is to determine job sequence, tool spare requirement and corresponding replacement intervals so that the total expected processing cost is minimized. Due to the combinatorial nature of the problem, a tabu search approach is proposed to find good and quick solutions. An example prob...

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...

Virtual machines (VM) are promising as system software in sensor networks. A major impediment to their widespread acceptance is the performance overhead. Compiling VM bytecode to native code addresses this, but increases footprint and cost of distributing the code. We describe a remote Just-In-Time (JIT) framework that is effective in combining interpretation with native execution to achieve an...

This paper investigates the reduction of variance associated with a simulation output performance measure, using the Sequential Sampling method while applying minimum simulation replications, for a class of JIT (Just in Time) warehousing system called crossdocking. We initially used the Sequential Sampling method to attain a desired 95% confidence interval half width of ± 0.5 for our chosen per...

Exclusion of the head from total-body dual-energy X-ray absorptiometry (DXA) scans is recommended when measuring pediatric bone mass (1,2).We write to suggest that a similar approach, that is, total body less head (TBLH) measurement, should be considered when measuring total-body lean mass in adults. DXA-measured total-body lean mass is often used as a surrogate for muscle mass in athletic perf...

Background: As health care struggles to meet increasing demands with limited resources, Lean Management is becoming a popular management approach. More is known about operational aspects of Lean application than about the socio-technical aspects such as how Lean interacts with teamwork and the psychosocial work environment. It is also unclear why and how organizations adopt Lean. Aim: This proj...

value stream mapping because of being able to understand process bottlenecks, as one of the most common tools for analyzing, identifying and eliminating various losses in operational and support processes are used. on the other hand, inventory management, precise control entry and exit of goods, accurate and timely information about the inventories status and planning, reduce product maintenanc...

Through literature review and drawing from a combined professional experience of over 20 years of lean construction implementation, this paper investigates the key success factor for the automotive industry’s uptake of lean production to see what the construction industry can derive from it. The paper concludes that there exist a variety of definitions of lean, but no existing definition is yet...
