Process Improvement Programs (PIPs) such as Total Quality Management, Six Sigma, JIT, and Lean have been the subject of much research over the last two decades. Most research on PIPs examines one specific type of PIP and attempts to evaluate the impact of specific PIP practices on performance. While most scholars agree that PIP research is extremely important, they also agree that it is difficu...

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...

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...

Virtual machines (VM) are promising as system software in networks of embedded systems and pervasive computing spaces. VMs facilitate the development of platformindependent applications with small footprints to enable low cost application distribution and evolution. A major impediment to their more widespread acceptance is the performance overhead of interpretation. Compiling VM bytecode to nat...

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...

This paper reviews the Operational Improvement approaches of the last 30 years in Australia. They have included Group Technology, ERP, JIT, WCM, BP-R, TQM and Now Lean Manufacturing. It identifies what each approach consists of, the initial launch, implementation efforts and results. The paper finds that only the WCM program has had any real success. The reasons for the high failure rate for th...

Interactive search of complex data poses significant challenges for traditional indexing methods because of the infeasibility of determining an effective set of indices a priori. This paper proposes just-in-time indexing, a new strategy that mitigates these challenges by exploiting a key characteristic of interactive data exploration: iterative query refinement. During the refinement process, j...
