In modern times, far-reaching changes especially in production have taken place. Lean manufacturing systems require delivery strategies such as just-in-time or just-in-sequence that are synchronized with production demand to make sure the optimal amount of inventory is on hand at any time. This development comes along with both increasing dependence and cross-linking of inhouse-logistics system...

One of the most important tasks of automatic tool monitoring systems for CNC-lathes is the supervision of a tool's wear. Considering the state of wear and the actual working process (e.g. rough or nish turning) it is possible to exchange a tool (or only the insert) just in time, which o ers signi cant economic advantages. This paper presents a new method to estimate two wear parameters by means...

We study the approximability of minimum total weighted tardiness with a modified objective which includes an additive constant. This ensures the existence of a positive lower bound for the minimum value. Moreover the new objective has a natural interpretation in Just-In-Time production systems.

The focus of this chapter is the provision of teacher professional development as needed – just in time. The specific context is the application of peer mentoring in teaching and learning with interactive whiteboards. Data was gathered from two research projects that investigated aspects of teachers mentoring colleagues in Australia. In both projects lessons were video recorded and the teachers...

Lean manufacturing impacts several operational performances. The usefulness of JIT links with suppliers is also well known. However, literature lacks strong empirical evidences to exhibit the relationship between lean manufacturing, operational performances and JIT linkages with suppliers. This paper aims to investigate this relationship. A questionnaire-based international survey was used to o...
